Description

Rolling guide automatic cutting production line

technical field

The utility model belongs to the technical field of mechanical cutting equipment, and in particular relates to a rolling guide rail automatic cutting production line.

Background technique

Rolling guides are widely used in modern CNC machine tools and automation equipment. At present, most of the rolling guides used in China are imported. Considering the precision, economy, and convenience of transportation, rolling guide rails are generally made to be about 4 meters long and have a variety of widths, and the commonly used ones are generally between 15 mm and 65 mm. However, different users have different requirements for the specification and length of the guide rail, which requires corresponding cutting of the guide rail. Therefore, most of the rolling guide rail agents need to cut the guide rails in large quantities and in multiple varieties before distribution.

There are two traditional ways of cutting rolling guide rails. One is manual feeding, hydraulic clamping, and cutting with a special cutting machine. Since the material of the rolling guide rails is alloy steel and has been quenched, the hardness is very high, and traditional cutting methods cannot be used. Cutting with a special tool can only be cut by grinding with a grinding wheel. The distance between the cutting end surface of the rolling guide rail and the installation positioning hole has precision requirements, and manual feeding is difficult to control the precision, and the efficiency is very low. The second way is to manually insert a taper pin in the installation and positioning hole of the rolling guide as a positioning reference, and automatically feed and cut. The pin also serves as a transmission mechanism, so the position is fixed. The installation hole is aligned with the pin, which is very inefficient, and the pin and the hole are in line contact, and the lateral position cannot be limited (the width specification is different), so it is easy to shake left and right during transmission. On the fixture, the reference plane on the same side is positioned, and the other side is clamped, and the guide rail will be deformed to a certain extent, thereby affecting the accuracy of the guide rail.

Both the automatic feeding device 1 and the blanking device 3 are equipped with an initial positioning mechanism 4, and the automatic feeding device 1 is equipped with a three-axis control mechanism: Z-axis transmission mechanism 5, Y-axis transmission mechanism 6 and X-axis transmission mechanism 7.

The initial positioning mechanism 4 is mainly to limit the bottom surface and the side of the rolling guide rail 13 in transportation, so as to ensure that the surface of the rolling guide rail 13 will not be damaged due to relatively large rigid friction with the device during transportation. Mechanism 4 includes a bottom limit assembly and a side limit assembly.

When manual feeding is carried out on the automatic feeding device 1, the The position plate 43 moves upwards along the slide rail 48 under the action of the cylinder one 45 so as to withstand the right side of the rolling guide rail 13 to limit the position. The following three-axis control pin and visual recognition and other steps.

The rolling guide rail is conveyed from left to right on the automatic feeding device, so in general, the positioning hole at the leftmost end of the rolling guide rail is used as the reference hole, and the pin is used for positioning. Generally, pin positioning adopts the method of centering, but since the diameters of the positioning holes of various specifications of rolling guides are different, in order to use one pin to locate all specifications of rolling guides, this design creatively uses the tangent point as the Positioning reference, that is, the diameter of the pin is determined based on the smallest size of the rolling guide rail installation hole (less than the positioning hole). Since the diameter of the pin is smaller than the positioning hole, the center of the hole cannot be determined. Therefore, this design uses a three-axis control mechanism to make the pin and the guide rail The positioning holes are tangent, and the position in the length direction of the guide rail is positioned based on the tangent point, so as to achieve accurate cutting.

Since the side of the rolling guide 13 is the same positioning reference, and the right end face is also the same reference, so for the rolling guide 13 of different specifications, the position of the first hole at the left end is different, so there must be X-axis and Y-axis movement Only then can the positioning holes of rolling guide rails 13 of different specifications be aligned.

The Y-axis transmission mechanism 6 is connected to the rear of the support plate 2 51, the left and right ends of the base plate 61 are provided with longitudinal slide rails 2 62, the rear of the base plate 61 is provided with a motor support 63, and the linear stepper motor 2 64 is connected At the rear of the motor support 63, the sliding plate 66 is connected with the linear stepping motor 2 64 through the telescopic push rod 65, and the sliding plate 66 can slide along the sliding track 2 62, and the Z-axis support 67 is fixedly connected on the front side of the sliding plate 66, The Z-axis support 67 is fixedly connected with the support plate 2 51, a guide plate is provided at the bottom of the base plate 61, and a guide through hole is provided on the guide plate.

Servo motor 171 drives ball screw 172 to rotate, so that the lead screw nut 77 connected to it moves linearly in the horizontal direction, so that the base plate 61 fixedly connected to the lead screw nut 77 can drive in the X-axis direction, and finally Drive the transmission of the Y-axis transmission mechanism 6 and the Z-axis transmission mechanism 5 in the horizontal direction, and after the pin 56 on the auxiliary Z-axis transmission mechanism 5 is successfully inserted into the positioning hole, it is tangent to the positioning hole, and the reference point is found. After the positioning is completed, the rolling guide rail 13 Under the horizontal transmission of the X-axis transmission mechanism 7, it is smoothly transported to the cutting device for cutting.

Since the diameters of the installation holes of the rolling guide rails 13 of different specifications and the distances from the left end face are different, in order to realize the automatic latch, on the basis of using the three-axis transmission mechanism, the utility model also adopts a visual recognition mechanism, mainly using the industrial The camera 8 is used for position recognition.

After the control system obtains the relevant coordinate data, the bolt moves to the accurate position through the three-axis control mechanism to complete the bolt action.

The reason why the utility model is provided with a clamping mechanism 10 in the material cutting device is mainly to relatively fix the position of the rolling guide rail 13 during cutting, so as to avoid its random movement or flying out during the cutting process, which not only affects the cutting process.
