Description

Five-axis motion platform

Technical Field

The present application relates to the field of multi-axis motion platforms, and in particular to a five-axis motion platform.

Background technique

During the machining process, it is often necessary to process different positions of the workpiece. Therefore, the machining head (cutter, grinding head, welding gun, dispensing head and other devices) and the workpiece should be able to form free relative movement. The direction of movement usually includes linear motion along the X-axis, Y-axis, and Z-axis, and rotational motion around the X-axis, Y-axis, and Z-axis. The five-axis motion platform can move the workpiece along the X-axis, Y-axis, and Z-axis, and rotate it around the X-axis and Y-axis.

In the related technology, the five-axis motion platform includes an X-axis slide, a Y-axis slide, a Z-axis slide, an X-axis turntable and a Y-axis turntable. The X-axis slide is usually fixed on a frame, the Y-axis slide is connected to the slide seat of the X-axis slide, the Z-axis slide is connected to the slide seat of the Y-axis slide, the X-axis turntable is connected to the slide seat of the Z-axis slide, and the Y-axis turntable is connected to the rotating seat of the X-axis turntable. The X-axis slide, the Y-axis slide and the Z-axis slide are all motor screw structures, so the motor axis of the Z-axis slide is perpendicular to the motor axis of the X-axis slide and the Y-axis slide.

Regarding the above-mentioned related technologies, there are two problems: first, the height in the direction of the motor axis will be used as part of the platform height; second, the gravity of the workpiece will produce bending moment on the screw and track of the Z-axis slide, and the bending moment will also produce a flipping force around the horizontal axis on the X-axis slide and the Y-axis slide, resulting in the defects of the platform's structure being not compact and the platform's adjustment accuracy being low after long-term use.

Summary of the invention

In order to make the structure of the motion platform more compact and maintain high-precision adjustment of the motion platform after long-term use, the present application provides a five-axis motion platform.

The five-axis motion platform provided in this application adopts the following technical solutions:

Five-axis motion platform, including:

X-axis slide;

A Y-axis slide, connected to the slide seat of the X-axis slide;

A Z-axis base connected to the slide of the Y-axis slide;

A Z-axis slide, slidably connected to the Z-axis base;

A Z-axis motor, arranged on the Z-axis base, wherein the output shaft of the Z-axis motor is parallel to the X direction or the Y direction;

A Z-axis guide seat, movably arranged on the Z-axis base, the Z-axis guide seat is connected to the output shaft of the Z-axis motor, the Z-axis guide seat is movably connected to the Z-axis slide, the Z-axis guide seat has a displacement guide surface abutting against the Z-axis slide, and different positions of the displacement guide surface have different distances from the output shaft of the Z-axis motor;

An X-axis turntable connected to the Z-axis slide;

The Y-axis turntable is connected to the rotating seat of the X-axis turntable.

By adopting the above technical solution, firstly, the axis of the Z-axis motor is parallel to the X-direction or the Y-direction, and the Z-axis motor can be set near the Z-axis slide in the horizontal direction, so the height of the platform will not be increased additionally by the Z-axis motor; secondly, the position of the Z-axis slide is achieved by changing the abutment position between the Z-axis slide and the Z-axis guide seat, and a part of the gravity transmitted to the Z-axis slide by the workpiece will be shared by the Z-axis guide seat, and the bending moment of the connecting track between the Z-axis slide and the Z-axis base will be smaller, and further the turning force of the X-axis slide and the Y-axis slide around the horizontal direction will also be smaller. In summary, the structure of the motion platform can be made more compact, and the high-precision adjustment of the platform can be maintained after long-term use.

Preferably, the Z-axis guide seat is threadedly connected to the output shaft of the Z-axis motor, the Z-axis guide seat is slidably connected to the Z-axis base, the Z-axis guide seat is slidably connected to the Z-axis slide, and the side of the Z-axis guide seat connected to the Z-axis slide is an inclined extending structure for forming the displacement guide surface.

By adopting the above technical solution, compared with the cam structure of the Z-axis guide seat, this design method, firstly, the contact force of the Z-axis guide seat on the Z-axis slide can pass through the center of gravity of the Z-axis slide, so the Z-axis guide seat can move the Z-axis slide more stably, thereby improving the adjustment stability; secondly, the inclined structure is easier to form, and it is also easier to calculate the proportional relationship between the moving stroke of the Z-axis guide seat and the moving stroke of the Z-axis slide, thereby reducing the manufacturing cost of the platform.

Preferably, the Z-axis guide seat is located below the Z-axis slide seat.

By adopting the above technical solution, compared with the method in which the Z-axis guide seat is located above the Z-axis slide, this design method does not require the addition of auxiliary supporting components to maintain stable contact between the displacement guide surface and the Z-axis slide, thereby making the structural form of the motion platform simpler.

Preferably, the inclination angle of the displacement guiding surface ranges from 15° to 75°.

By adopting the above technical scheme, if the inclination angle of the displacement guide surface is too small, the component force perpendicular to the displacement guide surface applied by the Z-axis slide to the Z-axis guide seat will be too large, thereby causing the friction between the Z-axis slide and the Z-axis guide seat to be too large; if the inclination angle of the displacement guide surface is too large, the pressure applied by the Z-axis slide to the Z-axis base will be too large, thereby causing the friction between the Z-axis slide and the Z-axis base to be too large. In summary, the angle range limitation of the displacement guide surface can make the movement of the Z-axis slide adjusted smoother.

Preferably, when performing heavy load and high-precision adjustment, the tilt angle of the displacement guide surface ranges from 15° to 45°.

By adopting the above technical solution, the travel ratio between the Z-axis guide seat and the Z-axis slide seat is less than 1, so it can be suitable for high-precision and heavy-load adjustment.

Preferably, when performing light load and low precision adjustment, the tilt angle of the displacement guide surface ranges from 45° to 75°.

By adopting the above technical solution, the travel ratio between the Z-axis guide seat and the Z-axis slide seat is greater than 1, so it can be suitable for low-precision and light-load adjustment.

Preferably, the X-axis turntable and the Y-axis turntable have the same structure, and both turntables include a fixed base, a rotating base, a driving seat, a conversion connector and a swing motor, the fixed base is connected to the Z-axis slide or the rotating seat of another turntable; the rotating seat is slidably connected to the fixed base, and the sliding track is an arc-shaped extension structure; the driving seat is slidably connected to the fixed base, and the movement direction of the driving seat is parallel to the X direction or the Y direction; the conversion connector connects the driving seat and the rotating seat, and is used to convert the linear motion of the driving seat into the rotation of the rotating seat; the swing motor is arranged on the fixed base, and the output shaft of the swing motor is threadedly connected to the driving seat.

By adopting the above technical solution, when the output shaft of the swing motor rotates, the driving seat will move along the axis of the output shaft of the swing motor. In this process, the driving seat can move the rotating seat through the conversion connecting piece, and the track between the rotating seat and the fixed base is extended in an arc shape, so as to realize the rotation of the rotating seat. Compared with the method of directly rotating the turntable by the motor, in this design method, the swing motor can be located near the horizontal plane of the fixed base, so the height of the platform will not be increased by the swing motor, thereby maintaining the compactness of the structure of the motion platform.

Preferably, the conversion connecting member includes an active push plate and a driven connecting shaft, the active push plate is connected to the driving seat, and two active push plates are arranged at intervals; the driven connecting shaft is connected to the rotating seat, and the driven connecting shaft is arranged in the gap between the two active push plates, the driven connecting shaft is cylindrical, and there is sliding and rolling abutment between the driven connecting shaft and the active push plate.

By adopting the above technical solution, compared with the method of connecting the driving seat and the rotating seat through a telescopic rod with two hinged joints connected at the ends, in this design method, the connection between the driven connecting shaft and the active push plate is a contact connection, rather than a through-type connection that requires the use of bolts. Therefore, the structure of the X-axis turntable and the Y-axis turntable can be simpler, and the swing of the rotating seat can be smoother.

Preferably, the driven connecting shaft is sleeved with a plurality of connecting bearings along the axis line, and the plurality of connecting bearings are divided into two groups, wherein one group of connecting bearings abuts against one of the active thrust plates, and the other group of connecting bearings abuts against the other active thrust plate.

By adopting the above technical solution, firstly, when relative sliding occurs between the driven connecting shaft and the active push plate, the sliding friction can be reduced by means of the rotation of the inner ring and the outer ring of the connecting bearing; secondly, only one side of each set of connecting bearings will abut against the active push plate, so the friction on the driven connecting shaft can also be reduced. In summary, the relative movement between the driving seat and the rotating seat can be smoother.

Preferably, the Z-axis motor and the motor of one of the X-axis slide or the Y-axis slide and one of the swing motors are on the same side of the motion platform, and the motors of the remaining turntables and slides are on the other side of the motion platform.

By adopting the above technical solution, the arrangement of the various components in the motion platform in space will be more compact, so that the volume occupied by the motion platform can be smaller.

In summary, the present application includes at least one of the following beneficial technical effects:

First, if the axis of the Z-axis motor is parallel to the X-direction or the Y-direction, the Z-axis motor can be set near the Z-axis slide in the horizontal direction, so the height of the platform will not be increased by the Z-axis motor; second, the position of the Z-axis slide is achieved by changing the position of the Z-axis slide in contact with the Z-axis guide seat, so the gravity transmitted to the Z-axis slide by the workpiece will be partially shared by the Z-axis guide seat, and the bending moment of the connecting track between the Z-axis slide and the Z-axis base will be smaller, and further the turning force of the X-axis slide and the Y-axis slide around the horizontal direction will be smaller. In summary, the structure of the motion platform can be more compact, and the high-precision adjustment of the platform can be maintained after long-term use;

Compared with the cam structure of the Z-axis guide seat, this design method has the following advantages: firstly, the contact force of the Z-axis guide seat on the Z-axis slide can pass through the center of gravity of the Z-axis slide, so the Z-axis guide seat can move the Z-axis slide more stably, thereby improving the adjustment stability; secondly, the inclined structure is easier to form, and it is also easier to calculate the proportional relationship between the moving stroke of the Z-axis guide seat and the moving stroke of the Z-axis slide, thereby reducing the manufacturing cost of the platform.

Detailed ways

The present application is further described in detail below in conjunction with Figures 1-3.

The embodiment of the present application discloses a five-axis motion platform. Referring to Figure 1, the five-axis motion platform includes an X-axis slide 1, a Y-axis slide 2, a Z-axis base 3, a Z-axis slide 31, a Z-axis motor 32, a Z-axis guide seat 33, an X-axis slide 1 and a Y-axis slide 2. The X-axis slide 1 is usually fixed to an external frame when in use, and the X-axis slide 1 is a motor screw structure; the Y-axis slide 2 is connected to the slide of the X-axis slide 1, and the Y-axis slide 2 is also a motor screw structure; the Z-axis base 3 is fixedly connected to the slide of the Y-axis slide 2; the Z-axis motor 32 is fixedly connected to the Z-axis base 3, and the output shaft of the Z-axis motor 32 is parallel to the X direction and the Y direction, where the X direction and the Y direction can be considered to be the X axis and the Y axis in the reference system.

Referring to Figure 1, the Z-axis guide seat 33 is movably connected to the Z-axis base 3, the Z-axis guide seat 33 is connected to the output shaft of the Z-axis motor 32, and the Z-axis guide seat 33 is movably connected to the Z-axis slide 31. At the movable connection, the Z-axis guide seat 33 will have a displacement guide surface 331 abutting against the Z-axis slide 31, wherein the distances between different positions of the displacement guide surface 331 and the output shaft of the Z-axis motor 32 are different, so the lifting and lowering of the Z-axis slide 31 can be achieved by changing the abutting position of the Z-axis slide 31 on the displacement guide surface 331; the X-axis is rotatably connected to the Z-axis slide 31; the Y-axis turntable 5 is connected to the rotating seat 61 of the X-axis turntable 4.

1 , the motion platform has the following advantages. First, the axis of the Z-axis motor 32 is parallel to the X-direction or the Y-direction, so the Z-axis motor 32 can be set near the Z-axis slide 31 in the horizontal direction, so the height of the platform will not be increased by the Z-axis motor 32. Second, the position of the Z-axis slide 31 is achieved by changing the abutment position between itself and the Z-axis guide seat 33, so the gravity transmitted by the workpiece to the Z-axis slide 31 will be partially shared by the Z-axis guide seat 33, and the bending moment of the connecting track between the Z-axis slide 31 and the Z-axis base 3 will be smaller, and further, the flipping force on the X-axis slide 1 and the Y-axis slide 2 around the horizontal direction will also be smaller. The flipping force here can be understood as the force that makes the slides of the X-axis slide 1 and the Y-axis slide 2 tilt upward, thereby making the structure of the motion platform more compact and maintaining high-precision adjustment of the platform after long-term use.

Referring to Figure 1, in order to allow the Z-axis guide seat 33 to adjust the Z-axis slide 31 more stably while keeping the structural form of the motion platform simple, the following settings are correspondingly made: the Z-axis guide seat 33 is located below the Z-axis slide 31, and the Z-axis guide seat 33 and the output shaft of the Z-axis motor 32 are connected by a screw structure to achieve a threaded transmission connection. The Z-axis guide seat 33 is slidably connected to the Z-axis base 3, and the movement direction of the Z-axis guide seat 33 is parallel to the X direction or the Y direction. The Z-axis guide seat 33 and the Z-axis slide 31 are also slidably connected, and the Z-axis guide seat 33 has an inclined surface at the connection point. This Z-axis slide 31 is slidably connected to this inclined surface, so this inclined surface is the displacement guide surface 331 used to change the position of the Z-axis slide 31. In summary, first, the contact force of the Z-axis guide seat 33 on the Z-axis slide 31 can pass through the center of gravity of the Z-axis slide 31, so the movement of the Z-axis slide 31 is more stable, so the adjustment stability can be improved; second, the inclined surface on the Z-axis guide seat 33 is easy to manufacture, and the stroke ratio relationship between the Z-axis guide seat 33 and the Z-axis slide 31 can also be calculated, so as to facilitate the control system to operate the motion platform, so the manufacturing cost of the motion platform can also be reduced.

In other embodiments, the following settings may also be provided: first, if the volume of the Z-axis slide 31 is small and the load-bearing parameters of the Z-axis slide 31 are small, the Z-axis guide seat 33 may also be a cam structure, so as to realize the lifting and lowering of the Z-axis slide 31 by taking advantage of the different distances between different positions on the circumference of the cam and the cam rotation center; second, if the installation space below the Z-axis slide 31 is insufficient, the Z-axis guide seat 33 may be located above the Z-axis slide 31, but an additional support member is required to maintain the abutment between the Z-axis slide 31 and the displacement guide surface 331.

Referring to Figure 1, in order to consider both the smoothness of the relative movement between the Z-axis slide 31 and the Z-axis guide seat 33 and the smoothness of the relative movement between the Z-axis slide 31 and the Z-axis base 3, the angle range of the tilt angle of the displacement guide surface 331 will be limited to between 15° and 75°. Specifically, if heavy-load adjustment and high-precision adjustment are to be achieved, the angle range of the tilt angle of the displacement guide surface 331 is between 15° and 45°, at which time the stroke ratio between the Z-axis guide seat 33 and the Z-axis slide 31 is less than 1. If light-load adjustment and low-precision adjustment are to be achieved, the angle range of the tilt angle of the displacement guide surface 331 is between 45° and 75 degrees, at which time the stroke ratio between the Z-axis guide seat 33 and the Z-axis slide 31 is greater than 1. From the perspective of a wide range of applications, the tilt angle of the displacement guide surface 331 is recommended to be 45°.

1 , in the present embodiment, the structures of the X-axis turntable 4 and the Y-axis turntable 5 are consistent, and each turntable includes a fixed base 6, a rotating base 61, a driving base 62, a conversion connector 63 and a swing motor 64, wherein the fixed base 6 is a basic reference system of the turntable, wherein the fixed base 6 of the X-axis turntable 4 is connected to the Z-axis slide 31, and the fixed base 6 of the Y-axis turntable 5 is connected to the rotating base 61 of the X-axis slide 1; the rotating base 61 is slidably connected to the fixed base 6, and the sliding track is an arc-shaped extension structure, and the center of the circle where the sliding track is located is located above the fixed base 6; the driving base 62 is slidably connected to the fixed base 6, and the movement direction of the driving base 62 is also parallel to the X direction or the Y direction.

Referring to Figure 1, the conversion connector 63 connects the driving seat 62 and the rotating seat 61. The function of the conversion connector 63 is to allow the linear motion of the driving seat 62 to be converted into the rotation of the rotating seat 61, so the conversion connector 63 needs to be compatible with linear motion and circular motion. Specifically, a structure combining a telescopic rod and a hinge joint can be selected; the swing motor 64 is fixedly connected to the fixed base 6, and the output shaft of the swing motor 64 is threadedly connected to the driving seat 62 through a screw structure. Therefore, while realizing the rotation of the rotating seat 61, the swing motor 64 can be located near the fixed base 6 along the horizontal plane, and the height of the platform will not be additionally increased by the swing motor 64, thereby further maintaining the compactness of the structure of the motion platform.

Referring to Figure 1, in order to further simplify the structure of the X-axis turntable 4 and the Y-axis turntable 5 and at the same time improve the swinging smoothness of the rotating seat 61, the conversion connecting member 63 includes an active push plate 631 and a driven connecting shaft 632. The active push plate 631 is fixedly connected to the upper surface of the driving seat 62. Two active push plates 631 are provided. The two active push plates 631 are spaced apart, and the length of the spacing is perpendicular to the movement direction of the driving seat 62; the driven connecting shaft 632 is fixedly connected to the rotating seat 61, and the driven connecting shaft 632 is in the spacing between the two active push plates 631. The driven connecting shaft 632 is cylindrical in shape, and there is sliding and rolling contact between the driven connecting shaft 632 and the active push plate 631, so that the rotating seat 61 can be rotated by the linear motion of the driving seat 62. At the same time, the above structure does not involve components such as bolts, so the internal friction of the conversion connecting member 63 itself will be smaller, thereby making the rotation of the rotating seat 61 smoother.

1 , in order to further reduce the friction at the connection between the rotating seat 61 and the driving seat 62 , the driven connecting shaft 632 will be provided with a plurality of connecting bearings 633 along the axis, and the plurality of connecting bearings 633 will be divided into two groups, one group of connecting bearings 633 will abut against one of the active thrust plates 631 , and the other group of connecting bearings 633 will abut against the other active thrust plate 631 . Then, firstly, when relative sliding occurs between the driven connecting shaft 632 and the active thrust plate 631 , the sliding friction can be reduced by means of the rotation of the inner and outer rings of the connecting bearings 633 ; secondly, only one side of each group of connecting bearings 633 will abut against the active thrust plate 631 , so the friction on the driven connecting shaft 632 can also be reduced, thereby making the relative movement between the driving seat 62 and the rotating seat 61 smoother.

Referring to Figure 1, in order to make the space occupied by the platform smaller, the Z-axis motor 32 and the motor of one of the X-axis slide 1 or the Y-axis slide 2, and one of the swing motors 64 are on the same side of the motion platform, and the motors of the remaining turntable and slide are on the other side of the motion platform. The arrangement of the various components in the motion platform in space will be more compact, thereby making the volume occupied by the motion platform smaller.

The implementation principle of a five-axis motion platform in the embodiment of the present application is as follows: first, if the axis of the Z-axis motor 32 is parallel to the X-direction or the Y-direction, the Z-axis motor 32 can be set near the Z-axis slide 31 in the horizontal direction, so the height of the platform will not be increased additionally by the Z-axis motor 32; second, the position of the Z-axis slide 31 is achieved by changing the abutment position between itself and the Z-axis guide seat 33, then a part of the gravity transmitted by the workpiece to the Z-axis slide 31 will be shared by the Z-axis guide seat 33, and the bending moment of the connecting track between the Z-axis slide 31 and the Z-axis base 3 will be smaller, and further, the flipping force on the X-axis slide 1 and the Y-axis slide 2 around the horizontal direction will also be smaller. The flipping force here can be understood as the force that makes the slides of the X-axis slide 1 and the Y-axis slide 2 tilt upward, thereby making the structure of the motion platform more compact and maintaining high-precision adjustment of the platform after long-term use.

The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
