Description

Technical Field

[0001] This utility model relates to the field of stamping technology, and in particular to a clamping and positioning fixture for stamping gasket production. Background Technology

[0002] Washers are small components commonly used in mechanical connections. They are usually formed by punching holes in a metal disc to create a metal ring. Their main function is to buffer, isolate, and seal between two fasteners. Washer stamping is mainly for standardized production centered on molds, to achieve a balance between high precision, high efficiency, and low cost.

[0003] In daily life, there is often a lack of a device to fix the gasket during stamping. When vibration occurs during stamping or when the punch comes into contact with the gasket, the gasket may shift or move, which will affect the quality and efficiency of gasket stamping. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the prior art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a clamping and positioning fixture for stamping gasket production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A clamping and positioning fixture for stamping in washer production includes a worktable. The upper surface of the worktable is provided with a stamping assembly for punching. A cylinder is fixedly connected to the upper surface of the worktable. A movable plate is fixedly connected to one end of the cylinder's telescopic part.

[0007] As a further embodiment of this utility model, the power assembly includes an electric telescopic rod, which is fixedly connected to the bottom inner wall of the housing. One end of the telescopic part of the electric telescopic rod is fixedly connected to a connecting plate. Two L-shaped rods are rotatably connected to both sides of the guide rail via bearings. The top of the housing has multiple through slots, through which the multiple L-shaped rods pass. A first guide slot is formed on one side of the multiple L-shaped rods inside the housing. Two connecting rods that move along the groove direction of the first guide slot are fixedly connected to both sides of the connecting plate. A second guide slot is formed on one side of the multiple L-shaped rods outside the housing. Connecting shafts that move along the groove direction of the second guide slot are fixedly connected to both sides of the two clamps.

[0008] As a further embodiment of this utility model, the stamping assembly includes a hydraulic cylinder, which is fixedly connected to the top of the L-shaped plate. One end of the telescopic part of the hydraulic cylinder is fixedly connected to a mounting block, and the bottom of the mounting block is provided with a mounting groove.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0021] Reference Figures 1-3A clamping and positioning fixture for stamping in washer production includes a worktable 1. A cylinder 8 is bolted to the upper surface of the worktable 1. A movable plate 7 is bolted to one end of the telescopic part of the cylinder 8. A housing 9 is bolted to one side of the movable plate 7. A placement rack 6 for placing metal round plates is welded to the upper surface of the housing 9. A through hole 20 is formed at the center of the upper surface of the placement rack 6. A guide rail 26 is bolted to the upper surface of the housing 9 below the placement rack 6. Clamps 19 are slidably connected to the top of the guide rail 26 on both sides of the placement rack 6. The side opening has a V-shaped groove. When it is necessary to fix the metal round plate, the metal round plate is placed on the placement rack 6, and then the two clamps 19 move towards each other along the guide rail 26. The two clamps 19 clamp and fix the metal round plate on the placement rack 6 through the V-shaped groove. During the clamping process, since the two clamps 19 move synchronously, the V-shaped groove will correct the metal round plate, so that the metal round plate is located at the center of the placement rack 6, thereby aligning the center point of the metal round plate with the center point of the through hole 20, thereby positioning and clamping the metal round plate and preventing the metal round plate from moving during the stamping process.

[0022] In this utility model, the housing 9 is provided with a power assembly that enables the two clamps 19 to move towards or away from each other. The power assembly includes an electric telescopic rod 17, which is fixed to the bottom inner wall of the housing 9 by bolts. One end of the telescopic part of the electric telescopic rod 17 is fixed to a connecting plate 23 by bolts. Two L-shaped rods 24 are rotatably connected to both sides of the guide rail 26 by bearings. The top of the housing 9 has multiple through slots 21, through which the multiple L-shaped rods 24 pass. A first guide groove 25 is provided on one side of the multiple L-shaped rods 24 inside the housing 9. Two connecting rods 22 that move along the groove direction of the first guide groove 25 are welded to both sides of the connecting plate 23. Each of the L-shaped rods 24 has a second guide groove 28 on one side outside the housing 9. Both sides of the two clamps 19 are welded with connecting shafts 18 that move along the groove direction of the second guide groove 28. When the electric telescopic rod 17 is activated to retract, the electric telescopic rod 17 drives the connecting plate 23 to move downward. The downward movement of the connecting plate 23 causes the connecting rod 22 to move downward in the first guide groove 25. At this time, the L-shaped rod 24 will rotate. During the rotation, the L-shaped rod 24 will push the two clamps 19 to move towards each other along the guide rail 26 through the connecting shaft 18. At the same time, the connecting shaft 18 will be displaced in the second guide groove 28, so that the two clamps 19 clamp and fix the metal round plate through the V-groove.

[0023] The electric telescopic rod 17 has a self-locking function, model KD56, which enables the clamp 19 to stably clamp the metal round plate through the self-locking function.

[0024] In this invention, the upper surface of the workbench 1 is provided with a punching assembly for punching. The punching assembly includes a hydraulic cylinder 3, which is fixed to the top of the L-shaped plate 2 by bolts. One end of the telescopic part of the hydraulic cylinder 3 is fixed to a mounting block 4 by bolts. The bottom of the mounting block 4 is provided with a mounting groove 11, and a punch 27 is connected to the mounting groove 11 through a quick-release assembly. The center point of the through hole 20 is perpendicular to the center point of the punch 27. When punching is required, the cylinder 8 is activated to extend, and the cylinder 8 will push the moving plate 7 to move. The moving plate 7 will carry... The moving housing 9 moves, which in turn moves the placement rack 6, causing the clamped metal disc to move downwards towards the punch 27. Since the center point of the through hole 20 is perpendicular to the center point of the punch 27, the center point of the punch 27 and the center point of the metal disc are aligned on the same vertical line. Then, the hydraulic cylinder 3 is activated to extend, pushing the mounting block 4 downwards. The mounting block 4 then moves the punch 27 downwards, causing the punch 27 to punch a hole in the metal disc. At the same time, the through hole 20 will avoid the punch 27.

[0025] In this invention, the quick-release assembly includes a bidirectional lead screw 10, which is rotatably connected to the mounting block 4 via bearings. The mounting block 4 has two sliding grooves 14 communicating with the mounting slot 11. Connecting blocks 15 are slidably connected within the sliding grooves 14, and the bidirectional lead screw 10 passes through and is threadedly connected to the connecting block 15. Two insertion rods 12 are welded to one side of the connecting block 15. Two insertion holes 13 are provided on both sides of the punch 27, and the insertion rods 12 are inserted into the insertion holes 13. When the punch 27 needs to be replaced, rotating the bidirectional lead screw 10 causes the two connecting blocks 15 to move in opposite directions along the sliding grooves 14 through threaded engagement with the connecting block 15, thereby disengaging the insertion rods 12 from the insertion holes 13. At this point, the punch 27 can be disassembled. When the punch 27 needs to be installed, place the punch 27 into the mounting slot 11, and then reverse the bidirectional lead screw 10 so that the insertion rod 12 is inserted into the insertion hole 13, which facilitates the disassembly and replacement of the punch 27. A knob is welded through the mounting block 4 on one side of the bidirectional lead screw 10. A locking nut is threaded on the outer side of the bidirectional lead screw 10 outside the mounting block 4. The locking nut locks and fixes the bidirectional lead screw 10, so that the bidirectional lead screw 10 will not easily rotate. Multiple vertical plates are welded on the upper surface of the worktable 1. A guide rod 5 is welded between two opposing vertical plates, and the guide rod 5 passes through the moving plate 7. The guide rod 5 guides the movement of the moving plate 7.

[0026] Working principle: When needed, place the metal round plate on the placement rack 6, then activate the electric telescopic rod 17 to retract. The electric telescopic rod 17 drives the connecting plate 23 to move downward. The downward movement of the connecting plate 23 causes the connecting rod 22 to move downward within the first guide groove 25. At this time, the L-shaped rod 24 rotates. During the rotation, the L-shaped rod 24 pushes the two clamps 19 to move towards each other along the guide rail 26 through the connecting shaft 18. At the same time, the connecting shaft 18 will be displaced within the second guide groove 28, so that the two clamps 19 clamp and fix the metal round plate on the placement rack 6 through the V-shaped groove. During the clamping process, since the two clamps 19 move synchronously, the V-shaped groove will correct the metal round plate, so that the metal round plate is located at the center of the placement rack 6, thereby aligning the center point of the metal round plate with the center point of the through hole 20, thus positioning and clamping the metal round plate and preventing the metal round plate from moving during the stamping process.

[0027] When stamping is required, the cylinder 8 extends, which pushes the moving plate 7 to move along the guide rod 5. The moving plate 7 moves the housing 9, which in turn moves the placement rack 6, causing the clamped metal disc to move downwards towards the punch 27. Since the center point of the through hole 20 is perpendicular to the center point of the punch 27, the center point of the punch 27 and the center point of the metal disc are aligned on the same vertical line. Then, the hydraulic cylinder 3 extends, pushing the mounting block 4 downwards. The mounting block 4 moves the punch 27 downwards, causing the punch 27 to punch the metal disc. At the same time, the through hole 20 avoids obstructing the punch 27.

[0028] When the punch 27 needs to be replaced, rotate the double-acting screw 10. The double-acting screw 10 engages with the connecting block 15 through the thread, causing the two connecting blocks 15 to move in opposite directions along the slide groove 14, thereby disengaging the insert rod 12 from the insertion hole 13. At this time, the punch 27 can be disassembled. When the punch 27 needs to be installed, place the punch 27 into the mounting groove 11, and then reverse the double-acting screw 10 to insert the insert rod 12 into the insertion hole 13, thus facilitating the disassembly and replacement of the punch 27.

[0029] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
