Abstract

PURPOSE:To permit removal of burrs having intricate shapes by mounting a grinding device to a mechanism which is actuated by command signals to make controlled lifting movement and controlled horizontal rotation and disposing a mechanism which is actuated by command signals to make horizontal reciprocation and controlled rotation to the lower side thereof. CONSTITUTION:The grinding device 16 is actuated by a servo motor to make the combined motion of the controlled lifting in a Z direction and the controlled horizontal rotation in an alpha direction. On the other hand, a work W clamped on a table 30 is actuated by a servo motor to make the combined motion of the controlled horizontal reciprocation in an X direction and the controlled horizontal rotation in a theta direction. Optional three-dimensional contact of the circumferential face of a grinding wheel 19 and the arbitrary position of the work W is, therefore, permitted by executing the controlled motions in the Z, alpha, X, theta directions simultaneously. In addition, the angle between the grinding wheel 19 and the machining surface of the work W can be taken as desired.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a deburring device that presses a grinder against the surface of a casting to thereby remove burrs from the casting.

(Prior art) In recent years, a deburring device has been proposed in which the grinder is NC-controlled so that it can handle a wide variety of shapes. However, the grinder has the disadvantage of being a large device with a large movable range. Furthermore, conventional deburring devices have been limited in their scope of application, mainly by removing burrs formed on the outer periphery of a cast product, and cannot be applied to deburring complex shapes on the inside.

(Object of the Invention) The present invention was made with the aim of solving the above-mentioned problem, and it is possible to remove complicated-shaped scales even though the movement of the grinder and cast product is small. The purpose is to provide equipment.

(Structure of the Invention) Below, the structure of the present invention will be explained in detail based on illustrated examples. (1) is a base, and on the upper half of the base (1),
A gate-shaped frame (4) consisting of four pillars (2) (2) and a ceiling frame (3) is erected.
The guide rods (5) (5) are attached to the brackets (6) (6) on the inside of the upper part of the book support (2) (2), respectively.
It is erected through the

Each guide rod (5) (5) is attached to the first mounting frame (
The four corner portions of 7) are fitted to be able to move up and down via guide tubes (8) (8), and the mounting frame (7) is attached to the ceiling frame (3) and is driven by a ball screw by a servo motor (9). (not shown) to the lifting rod (11) of the drive unit (10).

Further, a first engagement shaft (12) is vertically installed at the lower part of the first mounting frame (7), and the first engagement shaft (12) is connected to the first engagement shaft (12) by a servo motor (not shown). Joint shaft (12)
The first rotating member (13
) are fitted and suspended.

A U-shaped support member (
14) is fixed, and a grinder device (16) is cantilevered from the lower part of the support member (14) via a mounting member (15).

In the grinder device (16), a grindstone (19) is rotated via a belt (18) by a motor (F) installed in the support member (14).

Two guide bars (21) (21) are installed horizontally on the top of the base (1) at appropriate intervals via support brackets (20) at both left and right ends of the base (1). The guide tubes (22) (22) are slidably fitted to both guide bars (21) (21), respectively, and both guide tubes (22) (22) are fitted to the second mounting frame (21). 23).

At the bottom of the second mounting frame (23), the base (1
) and is connected via a bracket (26) to a rod of a drive unit (25) which is operated by a servo motor (24) via a ball screw (not shown).

Further, a second engagement shaft (27) is erected on the upper part of the second mounting frame (23), and a servo motor (not shown) is connected to the second engagement shaft (27). A second rotating member (28) that performs horizontal rotation control movement around 27).
are mated and connected.

Further, a table (30) having a recess (29) in the center of the upper surface is fixed to the upper part of the second rotating member (28), and the table (30) is opened and closed by a cylinder (not shown). 30) A clamp claw (31) for attaching and detaching the upper workpiece (W) is attached.

With the above-described configuration, the grinder device (16) can perform lifting control movements in the arrow (Z) direction and in the arrow (-) direction by the operation of the servo motor (9) and the operation of a servo motor (not shown). The workpiece (W) clamped on the table (30) is moved in the direction of the arrow (X) by the operation of the servo motor (24) and the servo motor (not shown). It is designed to perform a combined movement of horizontal reciprocating control movement in the direction of arrow (θ) and horizontal rotation control movement in the direction of the arrow (θ).

Therefore, these arrows (Z) (-) (X) (θ)
By simultaneously controlling the direction of the grinding wheel (19
) can be brought into contact with any location on the workpiece (5) in a three-dimensional manner, and the angle formed by the grinding wheel (19) and the cutting surface of the workpiece can be arbitrarily set. The result is that the number of people is increasing.

(Operation of the Invention) In the state shown in the figure, the servo motor (9) and the first rotating member (13) are connected to the servo motor (24) and the second rotating member (28).
) by operating the servo motors (not shown),
The circumferential surface of the grindstone (19) is brought into contact with any part of the workpiece (W) where there is a climb.

After that, while operating the motor (17) and rotating the grindstone (19), the arrow (Z) (-) (X) (θ)
The grindstone (19) is moved relatively along the workpiece (W) by simultaneously applying control movements in the directions.

The state in which the grindstone (19) is in contact with the workpiece (G) at this time is shown in FIGS. 3 and 4. That is, the arrow (X) (
θ) By simultaneously performing control movements in the (a) direction, the circumferential surface of the grinding wheel (19) is always in contact with the outer circumferential surface of the workpiece (5) at right angles, resulting in a complex shape as shown in the figure. The burrs are removed by following the same pattern.

In addition, when cutting off the inner surface of the workpiece (W), insert the grindstone (19) inside the workpiece (W) and bring it into contact with the inner surface of the workpiece (W) as shown in Figure 5. (θ
) (a) By simultaneously performing each control movement in the direction, the rise on the inner circumferential surface is removed.

Note that it is also possible to move three-dimensionally and remove burrs by further compounding control movements in the arrow (Z) direction. Furthermore, in the above embodiment, the grindstone (19) is used as the workpiece (W).
Although an example has been described in which burrs are removed by bringing the tool into contact with the grinding surface at right angles, it is also possible to remove burrs by holding the tool at an arbitrary angle.

(Effects of the Invention) The present invention provides a mechanism in which a grinder device is attached to a mechanism that performs elevation control and horizontal rotation control by a drive device driven based on a command signal, and a grinder device is attached below the grinder device to be driven based on a command signal. The device has a mechanism that performs horizontal reciprocating control movement and horizontal rotation control movement using a drive device, and a table is attached to this mechanism, so even though the movement of each mechanism that makes up the device is small, it is complicated. This makes it possible to remove the shape distortion, which greatly helps in downsizing the device.
