Description

Technical Field

[0001] The utility model relates to the technical field of positioning and punching of plastic gaskets, in particular to a punching device for processing plastic gaskets which is convenient for positioning. Background Art

[0002] Plastic is a synonym for synthetic resin. It is a solid made of high-molecular substances as the main raw material, which is artificially processed into a useful shape. It does not include fibers, rubber, coatings and adhesives. It can be said that plastics meet the following three conditions: the material is a high-molecular substance, its shape is formed into a useful shape after artificial processing, and it is solid under normal conditions.

[0003] In the current plastic gasket punching equipment, the position of the punching head is mainly determined by infrared rays, such as the technical solution proposed in the Chinese utility model patent with publication number CN215698113U. When punching the plastic gasket, since the plastic gasket is thin and the punching head will vibrate during punching, it is easy to cause the surface of the plastic gasket to vibrate, which will cause the position of the plastic gasket to shift and reduce the quality of the punching. Therefore, it is particularly important to provide a device that can fix the position of the plastic gasket. In view of this, we propose a punching device for plastic gasket processing that is easy to position. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a punching device for processing plastic gaskets that is easy to position, so as to solve the technical problem that the current plastic gaskets are prone to displacement during punching, thereby reducing the punching quality.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a punching device for plastic gasket processing that is convenient for positioning, comprising a workbench with an opening on the upper surface, a placement groove on the upper end surface of the workbench, at least one group of springs fixedly connected to the bottom surface of the placement groove, a base fixedly connected to the top of the spring, a cavity opened inside the workbench, and a positioning component arranged in the cavity;

[0006] The positioning assembly includes a double-rod hydraulic cylinder fixedly placed on the inner wall of the workbench, the upper telescopic end A of the double-rod hydraulic cylinder is rotatably connected to two connecting rods, one end of the two connecting rods is rotatably connected to a positioning plate, the lower telescopic end B of the double-rod hydraulic cylinder is fixedly connected to a fixed block, both sides of the fixed block are fixedly connected to electric telescopic rods, and the two electric telescopic rods are fixedly connected to the two positioning plates.

[0007] Preferably, both sides of the upper surfaces of the workbench and the base are provided with sliding grooves, and the surface of the positioning plate is slidably connected in the sliding grooves.

[0008] Preferably, a support frame is fixedly connected to the upper surface of the workbench, and a rotating unit is arranged in the support frame;

[0009] The rotating unit comprises a servo motor fixedly arranged on the upper surface of the supporting frame, and an output end of the servo motor penetrates through the side wall of the supporting frame and is fixedly connected with a double-headed rotating rod.

[0010] Preferably, the surface of the double-headed rotating rod is fixedly connected to a limit rod A, and the lower surface of the support frame is symmetrically fixedly connected to limit rods B on both sides, and the surface of the limit rod A and the surface of the limit rod B are against each other.

[0011] Preferably, a punching assembly and a grinding assembly are fixedly arranged on both ends of the double-headed rotating rod respectively.

[0012] Preferably, a plastic gasket is provided on the upper surface of the base, and the lower surface of the positioning plate abuts against the upper surface of the plastic gasket.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. This device uses a double-rod hydraulic cylinder, which can drive the two limit plates to move left and right and up and down relative to each other through the telescopic ends at both ends, so that the limit plates can adjust the position according to plastic gaskets of different sizes and clamp their surfaces. During the clamping process, the base moves downward at the same time and squeezes the spring, so that the position of the base and the plastic gasket is fixed. After the processing of the plastic gasket is completed, the limit plate cancels the clamping of the base and the plastic gasket, so that the spring can be reset, and then the base and the plastic gasket are driven to pop up, so that the plastic gasket is on the upper surface of the workbench, which is convenient for the staff to take it.

[0015] 2. This device can rotate the double-headed rotating rod through the servo motor, and at the same time can limit the rotation angle of the double-headed rotating rod through the limit rod A and the limit rod B, ensuring that the punching assembly and the grinding assembly are respectively moved to the upper end center of the plastic gasket, which can make the punching and grinding of the plastic gasket more precise and improve the processing quality of the plastic gasket.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] Example: A punching device for plastic gasket processing that is easy to position, see Figures 1 to 4 , including a workbench 1 with an opening on the upper surface, a placement groove is provided on the upper end surface of the workbench 1, a group of springs 2 are fixedly connected to the bottom surface of the placement groove, the top of the spring 2 is fixedly connected to the base 3, a cavity is provided inside the workbench 1, and a positioning component 4 is arranged in the cavity; the positioning component 4 includes a double-rod hydraulic cylinder 401 fixedly placed on the inner wall of the workbench 1, the upper telescopic end A of the double-rod hydraulic cylinder 401 is respectively rotatably connected to two connecting rods 402, one end of the two connecting rods 402 is respectively rotatably connected to the positioning plate 403, the lower telescopic end B of the double-rod hydraulic cylinder 401 is fixedly connected to a fixed block, and electric telescopic rods 404 are respectively fixedly connected on both sides of the fixed block, and the two electric telescopic rods 404 are respectively fixedly connected to the two positioning plates 403, and the workbench 1 and the base 3 are provided with sliding grooves on both sides of the upper surface, and the surface of the positioning plate 403 is slidably connected in the sliding groove. By arranging the electric telescopic rod 404, when the positioning plate 403 moves in the horizontal direction, the connection between the double-rod hydraulic cylinder 401 and the positioning plate 403 can be ensured to be stable.

[0023] For details, see Figure 1 and Figure 2 The upper surface of the workbench 1 is fixedly connected to a support frame, and a rotating unit 5 is arranged in the support frame. The rotating unit 5 includes a servo motor 501 fixedly arranged on the upper surface of the support frame, and the output end of the servo motor 501 passes through the side wall of the support frame and is fixedly connected to a double-headed rotating rod 502. The surface of the double-headed rotating rod 502 is fixedly connected to a limiting rod A503, and the lower surface of the support frame is symmetrically fixedly connected to limiting rods B504 on both sides, and the surface of the limiting rod A503 is abutted against the surface of the limiting rod B504. By arranging the double-headed rotating rod 502, the punching assembly 6 and the grinding assembly 7 can be placed separately, so that the plastic gaskets can be processed separately.

[0024] For further information, see Figure 1 and Figure 2The two ends of the double-headed rotating rod 502 are respectively fixed with a punching assembly 6 and a grinding assembly 7, a plastic gasket 8 is provided on the upper surface of the base 3, and the lower surface of the positioning plate 403 is against the upper surface of the plastic gasket 8.

[0025] Working principle: This device can place the plastic gasket 8 that needs to be punched through the base 3, and then drive the connecting rod 402 to rotate inward in the clockwise direction through the contraction movement of the telescopic end A of the double-rod hydraulic cylinder 401, and at the same time drive the positioning plate 403 to move to the relative position, so that the positioning plate 403 is on both sides of the plastic gasket 8 and abuts against it, and then the telescopic end B of the double-rod hydraulic cylinder 401 follows the movement of the telescopic end A and stretches downward synchronously, so that the positioning plate 403 can clamp the upper surface of the plastic gasket 8 downward, and at the same time drive the base 3 to squeeze the spring 2 downward. When it is necessary to clamp a smaller plastic gasket 8, the electric telescopic rod 404 can be stretched to drive the positioning plate 403 to rotate clockwise around the connecting rod 402 and the connection with it, so that the top of the positioning plate 403 can contact the smaller plastic gasket 8 and It is clamped downward. After the position of the plastic gasket 8 is fixed, the double-headed rotating rod 502 can be controlled to rotate by the servo motor 501, so that the punching assembly 6 and the grinding assembly 7 can respectively operate on the plastic gasket 8. When the double-headed rotating rod 502 rotates, the limit rod A503 and the limit rod B504 can be used to limit the rotation angle of the double-headed rotating rod 502 to ensure that the punching assembly 6 and the grinding assembly 7 can be directly above the plastic gasket 8 when they need to operate. After the operation is completed, when the plastic gasket 8 needs to be taken away, the telescopic ends at both ends of the double-rod hydraulic cylinder 401 can be telescopically telescopically moved in the opposite direction to make the positioning plate 403 cancel the downward clamping force on the plastic gasket 8 and the base 3. At the same time, the spring 2 is reset to drive the base 3 to move upward, so that the plastic gasket 8 can be ejected in cooperation with the reset of the spring 2.
