[0001] This utility model relates to the field of mechanical manufacturing, and in particular to a punching fixture for gasket processing. Background Technology

[0002] A gasket is a thin sheet-like part, usually placed between two objects, used to fill gaps, adjust height, seal, dampen vibrations, insulate, or distribute pressure. It is widely used in machinery, construction, electronics, automobiles, pipelines, and other fields. A punching fixture for gasket processing is a device or tool specifically designed to process holes in gaskets. Its working principle is to drive the punch in the punching mechanism through a power source (such as an electric, pneumatic, or hydraulic device) to punch the gasket placed in a specific position, thereby forming the required hole in the gasket.

[0003] During the gasket processing, the workers place the gasket under the punch head, and then use external aids to hold the gasket in place to prevent it from moving during the stamping process and affecting product quality. Finally, the stamping operation is completed on the gasket by the punch head.

[0004] The existing technology has the following drawbacks: In existing equipment, the feeding and unloading of gaskets are usually done manually by workers. When the worker's hand is placed under the punching head to feed the material, the equipment may malfunction and cause injury to the worker's hand. The device has low safety. In addition, the existing gasket punching process lacks a positioning mechanism. When the gasket is moved by external force, it is easy to cause the punching position to deviate, which affects the product quality. Therefore, a punching fixture for gasket processing is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a punching fixture for gasket processing, which aims to improve the problems of insufficient safety of the existing device and the lack of a positioning mechanism during punching, which easily leads to positional deviation.

[0007] The movable mechanism includes an inclined block that is slidably connected to the top of the workbench. A protrusion is provided at the bottom of the inclined block, and the outer wall of the protrusion is elastically connected to the workbench by a moving spring. The bottom of the pressing rod is in contact with the upper surface of the inclined block.

[0008] As a further description of the above technical solution:

[0009] The collection assembly includes a baffle, the bottom end of which is elastically connected to a movable block via a movable spring. The inner wall of the workbench is provided with an extrusion groove, and a collection box is detachably installed on the inner wall of the workbench.

[0010] As a further description of the above technical solution:

[0011] The movable rod is slidably connected to the inner wall of the workbench.

[0012] As a further description of the above technical solution:

[0013] The extrusion rod is inserted into the inner wall of the worktable.

[0014] As a further description of the above technical solution:

[0015] A V-shaped opening is formed inside the movable block, and the lower part of the guide groove is formed in a vertical direction.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Referring to Figures 1-3, one embodiment of this utility model provides a punching fixture for gasket processing, including a worktable 1. A bracket 2 is fixedly connected to the top of the worktable 1, and the bracket 2 supports a telescopic rod 3. The telescopic rod 3 is provided on the inner wall of the bracket 2. The electric telescopic rod 3 is a mechanical device that achieves telescopic movement by being driven by a motor. A pressing rod 5 is fixedly connected to the outer wall of the movable end of the telescopic rod 3. The pressing rod 5 is U-shaped. A moving block 7 is slidably connected to the inner wall of the worktable 1. A slot corresponding to the moving block 7 is opened on the worktable 1, allowing the moving block 7 to move left and right. A guide groove 8 is opened on the inner wall of the moving block 7. A movable rod 6 is slidably connected to the inner wall of the guide groove 8. The upper part of the guide groove 8 is inclined. When the movable rod 6 presses the inclined section, the moving block 7 moves to the left. A movable mechanism is provided at the top of the worktable 1. The device is equipped with a collecting component and an active mechanism including a wedge block 12. The wedge block 12 is slidably connected to the top of the workbench 1. The workbench 1 has a slot corresponding to the wedge block 12, allowing the wedge block 12 to move back and forth. The bottom end of the telescopic rod 3 is fixedly connected to a punch head 4. The punch head 4 is a tool or component used to process holes in various materials and is widely used in manufacturing, processing, and handicraft industries. The bottom end of the wedge block 12 is provided with a protrusion. The outer wall of the protrusion is elastically connected to the workbench 1 through a moving spring 13. When the two sets of wedge blocks 12 approach each other, the moving spring 13 is compressed. When resetting, the elastic force of the moving spring 13 causes the two sets of moving springs 13 to separate from each other. The bottom end of the pressing rod 5 contacts the upper surface of the wedge block 12. The wedge block 12 is provided with an inclined surface. When the pressing rod 5 presses the inclined surface, it causes the two sets of wedge blocks 12 to approach each other.

[0035] Referring to Figures 1, 4, and 5, the collecting assembly includes a baffle 10. The bottom end of the baffle 10 is elastically connected to the moving block 7 via a movable spring 11. When the baffle 10 moves downward, the movable spring 11 is compressed. When resetting, the elastic force of the movable spring 11 carries the baffle 10 back to its original position. The inner wall of the worktable 1 is provided with a squeezing groove 14. A collecting box 9 is detachably installed on the inner wall of the worktable 1. The baffle 10 is inserted into the inner wall of the squeezing groove 14. When the squeezing groove 14 squeezes the baffle 10, it causes the baffle 10 to move downward.

[0036] Referring to Figures 1, 4, and 6, the movable rod 6 is slidably connected to the inner wall of the worktable 1. The worktable 1 has a slot corresponding to the movable rod 6, allowing the movable rod 6 to move vertically. The extrusion rod 5 is inserted into the inner wall of the worktable 1. The worktable 1 has a slot corresponding to the extrusion rod 5. A V-shaped opening is opened in the moving block 7, and the stamped waste material will fall into the collection box 9 from the opening. The lower part of the guide groove 8 is opened vertically. When the movable rod 6 continues to move downward and enters the vertical groove, it will no longer extrude into the guide groove 8. The movable rod 6 is fixedly connected to the left side wall of the extrusion rod 5. A rectangular groove with the same shape as the collection box 9 is opened in the worktable 1.

[0037] Working principle: When the gasket needs to be stamped, the operator can manually place the gasket on the moving block 7. Then, through the externally controlled telescopic rod 3, the telescopic rod 3 will move the movable rod 6 and the pressing rod 5 downward. The movable rod 6 will press the inclined guide groove of the guide groove 8, causing the moving block 7 to move the gasket to the left. When the gasket moves directly below the punch head 4, the movable rod 6 enters the vertical groove of the guide groove 8. The movable rod 6 no longer presses the guide groove 8, and the moving block 7 no longer moves. At the same time, the lower end of the pressing rod 5 will press the two sets of inclined blocks 12 to move closer together. The inclined blocks 12 will press the moving spring 13. When the two sets of inclined blocks 12 complete the positioning of the gasket, the outer wall of the inclined block 12 will contact the pressing rod 5 and remain stationary. At the same time, the pressing rod 5 will be inserted into the groove of the worktable 1 as the punch head 4 descends. When the punch head 4 contacts the gasket, the punch head 4 will perform punching operations on the gasket.

[0038] When punching is complete, the electrically controlled telescopic rod 3 moves upward, which in turn moves the pressing rod 5 and the movable rod 6 upward. As the pressing rod 5 no longer contacts the inclined block 12, it separates from the inclined block 12 under the elastic force of the moving spring 13, releasing the positioning of the gasket. At the same time, when the movable rod 6 moves upward and enters the inclined guide groove of the guide groove 8, the movable rod 6 will press the guide groove 8, allowing the guide groove 8 to move the movable block 7 to the initial position. If the gasket needs to be punched again, simply repeat the above operation steps.

[0039] When the moving block 7 moves below the punch head 4, the baffle 10 separates from the groove of the extrusion groove 14. Under the elastic force of the movable spring 11, the baffle 10 moves upward. The baffle 10 will block the V-shaped groove on the moving block 7. During stamping, the stamped waste will fall into the V-shaped groove. As the moving block 7 moves the baffle 10 to the initial position, when the baffle 10 contacts the extrusion groove 14, the extrusion groove 14 will squeeze the baffle 10 downward. The baffle 10 will squeeze the movable spring 11. When the baffle 10 is inserted into the extrusion groove 14, the baffle 10 will not block the V-shaped groove, and the waste will slide downward into the collection box 9. When the waste needs to be cleaned, simply remove the collection box 9.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
