Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to a clamping device for anti-deformation processing of thin-walled metal parts. Background Art

[0002] The clamping device for processing thin-walled metal parts is a special tool used to fix and support thin-walled metal parts to ensure that the parts will not move or deform during the processing.

[0003] Thin-walled metal parts have low deformation resistance due to their special structure. However, existing clamping devices often cannot accurately control the clamping force when clamping these parts, resulting in excessive pressure on certain key parts, making the parts easy to deform when subjected to external forces. Once thin-walled metal parts are deformed, their dimensional accuracy and shape stability will be seriously affected, which will not only reduce the overall performance of the parts, but also make the parts unable to meet the design requirements, resulting in a decrease in the overall quality of the product. Deformed parts also require additional repair and adjustment work, which undoubtedly increases processing costs and time costs and reduces production efficiency. Therefore, we propose a clamping device for anti-deformation processing of thin-walled metal parts. Utility Model Content

[0004] The purpose of the utility model is to provide a clamping device for anti-deformation processing of thin-walled metal parts, so as to solve the problem proposed in the above background technology that the existing clamping devices are often unable to accurately control the size of the clamping force when clamping these parts, resulting in excessive pressure being applied to certain key parts, making the parts easily deformed when subjected to external forces. Once the thin-walled metal parts are deformed, their dimensional accuracy and shape stability will be seriously affected, which will not only reduce the overall performance of the parts, but may also make the parts unable to meet the design requirements, resulting in a decrease in the overall quality of the product. The deformed parts also require additional repair and adjustment work, which undoubtedly increases the processing cost and time cost and reduces the production efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping device for anti-deformation processing of thin-walled metal parts, comprising a base, a bidirectional threaded rod is arranged at the center of the base, a crank is arranged on one side of the base, threaded plates are threadedly connected to both sides of the surface of the bidirectional threaded rod, a spacer is sleeved at the center of the surface of the bidirectional threaded rod, a first spring is sleeved on both sides of the surface of the bidirectional threaded rod, mounting brackets are fixedly connected to both sides of the base, clamping plates are arranged at both sides of the upper end of the base, anti-slip contacts are fixedly installed on the opposite sides of the two clamping plates, vertical plates are arranged on the opposite sides of the two clamping plates, fixed cylinders are fixedly installed on the tops of the opposite sides of the two vertical plates, opposite sides of the two fixed cylinders respectively penetrate to the outside of the two vertical plates, a second spring is fixedly connected to one side of the fixed cylinder, one end of the second spring is fixedly connected to the sliding plate, a connecting rod is fixedly connected to the center of one side of the sliding plate, and sliding grooves are provided on one side of the top and inner bottom of the fixed cylinder.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The clamping device for anti-deformation processing of thin-walled metal parts is designed with a two-way threaded rod, a threaded plate, a vertical plate, a clamping plate, an anti-slip contact, a first spring and a crank. When the crank is turned, the two-way threaded rod will drive the threaded plates on both sides to move toward or away from each other, thereby driving the clamping plates to clamp or release. Due to the design of the two-way threaded rod, the clamping plates on both sides can move synchronously and evenly, ensuring the uniform distribution of the clamping force on the parts. The setting of the first spring plays a buffering role and can provide a certain elasticity during the clamping process to avoid excessive clamping force and excessive pressure on the parts. At the same time, the design of the anti-slip contact increases the friction between the clamping plate and the parts, improves the stability of the clamping, and further reduces the risk of deformation of the parts. The design of the fixed cylinder, the connecting rod, the sliding plate, the sliding groove and the second spring is designed so that when the clamping plate performs a clamping action, the sliding plate will compress or stretch the second spring, thereby generating a reverse buffering force. This buffering force can reduce the direct impact of the clamping plate on the parts and avoid deformation of the parts caused by excessive clamping force. The clamping device can achieve uniform and stable clamping of thin-walled metal parts during the clamping process, while avoiding deformation of the parts caused by excessive clamping force. It not only improves processing accuracy and product quality, but also reduces production costs and time costs. BRIEF DESCRIPTION OF THE DRAWINGS

The opposite side of the holding plate 5 is fixedly installed with an anti-slip contact 6, the opposite side of the two clamping plates 5 is provided with a vertical plate 4, the top of the opposite side of the two vertical plates 4 is fixedly installed with a fixed cylinder 12, the opposite sides of the two fixed cylinders 12 respectively penetrate to the outside of the two vertical plates 4, one side inside the fixed cylinder 12 is fixedly connected with a second spring 16, one end of the second spring 16 is fixedly connected with a sliding plate 14, the center of one side of the sliding plate 14 is fixedly connected with a connecting rod 13, and one side of the top and the inner bottom of the fixed cylinder 12 is provided with a sliding groove 15.

[0015] One end of the bidirectional threaded rod 2 is movably connected to a bearing fixedly installed in the center of one side of the inner wall of the base 1, ensuring that the bidirectional threaded rod 2 can rotate freely in the base 1 while maintaining stable support. The other end of the bidirectional threaded rod 2 passes through the outside of the base 1 and the right-side mounting bracket 17 and is fixedly connected to one side of the crank 9, allowing the user to drive the rotation of the bidirectional threaded rod 2 by rotating the crank 9, thereby controlling the movement of the threaded plate 3.

[0016] The top and bottom of the spacer block 7 are fixedly connected to the top and bottom of the base 1 respectively, one end of the first spring 8 is fixedly connected to one side of the spacer block 7, and the other end of the first spring 8 is fixedly connected to one side of the threaded plate 3, providing a fixing point for the first spring 8.

[0017] Bottom transverse grooves are provided on both sides of the bottom of the base 1, and a guide rod 10 is fixedly connected between the two mounting brackets 17. Guide blocks 11 are slidably connected to the two sides of the surface of the guide rod 10. The tops of the two guide blocks 11 respectively penetrate the outside of the two bottom transverse grooves and are fixedly connected to the lower ends of the two threaded plates 3, providing guidance for the movement of the threaded plates 3 to ensure that they can move smoothly along the guide rods 10.

[0018] Top transverse grooves are provided on both sides of the top of the base 1, and the lower ends of the two vertical plates 4 respectively penetrate the outside of the two top transverse grooves and are fixedly connected to the tops of the two threaded plates 3, allowing the vertical plates 4 and the clamping plates 5 to move with the movement of the threaded plates 3 while maintaining their relative positions with the base 1.

[0019] The top and bottom of the sliding plate 14 extend to the interior of the two sliding grooves 15 respectively and are slidably connected to the inner walls of the sliding grooves 15. One end of the connecting rod 13 passes through the outside of the fixed cylinder 12 and is fixedly connected to the center of one side of the clamping plate 5, ensuring that the sliding plate 14 can slide smoothly in the fixed cylinder 12 while maintaining a stable connection with the connecting rod 13.

[0020] The two mounting brackets 17 are symmetrical L-shaped structures, and mounting holes are provided on the upper end surfaces of the mounting brackets 17 to facilitate mounting the entire clamping device on a workbench or other fixed locations.

[0021] When the user needs to clamp thin-walled metal parts, first rotate the crank 9. The crank 9 is fixedly connected to one end of the two-way threaded rod 2. Therefore, rotating the crank 9 will drive the two-way threaded rod 2 to rotate in the base 1. Since the threads on both sides of the surface of the two-way threaded rod 2 are in opposite directions, the two threaded plates 3 will move inward or outward at the same time. The specific movement direction depends on the rotation direction of the crank 9. When the threaded plates 3 move, they will drive the vertical plates 4 and the clamping plates 5 to move together, thereby clamping or releasing the thin-walled metal parts. Anti-slip contacts 6 are fixedly installed on the opposite side of the clamping plate 5. These contacts can increase the friction with the surface of the parts to prevent the parts from sliding during processing. In order to ensure uniform distribution of the clamping force and prevent deformation caused by excessive clamping force, a first spring 8 is provided in the device. One end of the first spring 8 is fixedly connected to the spacer 7, and the other end is fixedly connected to the threaded plate 3. When the threaded plate 3 moves, the first spring 8 will provide a reverse buffering force to prevent the clamping force from being too large. In addition, a buffering mechanism consisting of a second spring 16 and a sliding plate 14 is also provided in the device. The sliding plate 14 is fixedly connected to the connecting rod 13, and the connecting rod 13 is fixedly connected to the clamping plate 5. Therefore, when the clamping plate 5 clamps the part, the sliding plate 14 will slide in the fixed cylinder 12 and compress the second spring 16 at the same time. The reverse buffering force generated by the second spring 16 can further reduce the impact of the clamping force on the part and prevent the part from being deformed. The entire clamping device also ensures that the threaded plate 3 can move smoothly along the guide rod 10 through the guiding mechanism provided by the guide rod 10 and the guide block 11, thereby maintaining the stability and accuracy of the clamping. The mounting bracket 17 adopts a symmetrical L-shaped structure and has a mounting hole to facilitate the installation of the entire clamping device on a workbench or other fixed position.

[0022] To sum up: the clamping device for anti-deformation processing of thin-walled metal parts is designed through the design of the bidirectional threaded rod 2, the threaded plate 3, the vertical plate 4, the clamping plate 5, the anti-slip contact 6, the first spring 8 and the crank 9. When the crank 9 is turned, the bidirectional threaded rod 2 will drive the threaded plates 3 on both sides to move toward or away from each other, thereby driving the clamping plate 5 to clamp or release. Due to the design of the bidirectional threaded rod 2, the clamping plates 5 on both sides can move synchronously and evenly, ensuring the uniform distribution of the clamping force on the parts. The setting of the first spring 8 plays a buffering role and can provide a certain elasticity during the clamping process to avoid excessive clamping force and excessive pressure on the parts. At the same time, the design of the anti-slip contact 6 increases the friction between the clamping plate 5 and the parts, improves the stability of clamping, and further reduces the risk of deformation of the parts. The design of the fixed cylinder 12, the connecting rod 13, the sliding plate 14, the sliding groove 15 and the second spring 16, when the clamping plate 5 performs a clamping action, the sliding plate 14 will compress or stretch the second spring 16, thereby generating a reverse buffering force. This buffering force can reduce the direct impact of the clamping plate 5 on the parts and avoid deformation of the parts caused by excessive clamping force. The clamping device can achieve uniform and stable clamping of thin-walled metal parts during the clamping process and avoid deformation of the parts caused by excessive clamping force. It not only improves the processing accuracy and product quality, but also reduces production costs and time costs.
