Description

Technical Field

[0001] This utility model relates to the field of machining tooling technology, specifically to a machining tooling for preventing distortion of materials with large deformation. Background Technology

[0002] Anti-distortion machining fixtures for materials with large deformation are specialized clamping systems designed for highly elastic, low-stiffness, or superplastic materials (such as rubber, silicone, and thin-walled composite materials) that are prone to twisting, springback, or elongation deformation during processing. These fixtures are particularly suitable for applications such as precision cutting of flexible electronic substrates, micromachining of medical polymer components, and shape memory alloy molding.

[0003] Existing large deformation material processing fixtures, when machining thin-walled tubes and large deformation materials, often result in excessive clamping force applied to the workpiece during processing due to the thinness of the tubes and materials, leading to workpiece deformation and reduced processing quality. Furthermore, existing large deformation material processing fixtures do not facilitate the quick replacement of clamping plates in the clamping mechanism according to different workpiece specifications, resulting in reduced processing efficiency. Therefore, a new technical solution needs to be designed to address these issues. Utility Model Content

Detailed Implementation

[0021] 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.

[0022] Example 1: Please refer to again Figure 1-5This utility model provides a deformation-resistant processing fixture for materials subject to large deformation, including a mounting frame 100. Two bidirectional screws 110 are rotatably connected to the inner wall of the mounting frame 100. A motor 120 is fixedly connected to one side of the mounting frame 100. One end of the power output shaft of the motor 120 passes through the mounting frame 100 and extends into the inner cavity of the mounting frame 100. The power output shaft of the motor 120 is fixedly connected to one of the bidirectional screws 110. A connecting plate 130 is screwed to the outer side of the bidirectional screw 110. A mounting plate 140 is fixedly connected to one side of the connecting plate 130. Two outer cylinders 150 are fixedly connected to one side of the mounting plate 140. The inner side of the outer cylinders 150 is fixedly connected to... The device includes an inner cylinder 160, with a sealing ring 161 bonded to one end. The inner cavity of the inner cylinder 160 is filled with damping oil 162. A pressing rod 170 is inserted into one end of the inner cylinder 160. One end of the pressing rod 170 passes through the inner cylinder 160 and extends into the inner cavity of the inner cylinder 160. A pressure plate 171 is fixedly connected to one end of the pressing rod 170. A through hole 172 is opened on one side of the pressure plate 171 and the through holes 172 are evenly distributed. The other end of the pressing rod 170 is fixedly connected to the mounting base 200. A buffer spring 180 is fixedly connected to one end of the outer cylinder 150 and the buffer springs 180 are evenly distributed. One end of the buffer spring 180 is fixedly connected to the mounting base 200.

[0023] Specifically, the starting motor 120 drives the bidirectional screw 110 to rotate, causing the connecting plate 130 mounted on the bidirectional screw 110 to move the mounting plate 140, thus bringing the clamping mechanism closer to clamp the workpiece. After the clamping plate 210 clamps the workpiece, the mounting seat 200 applies pressure to the extrusion rod 170, causing the pressure plate 171 on the extrusion rod 170 to extrude the damping oil 162 in the inner cylinder 160. This causes the damping oil 162 to flow through the through hole 172 on the pressure plate 171 to the other side of the pressure plate 171, generating a damping force. At the same time, the movement of the oil extrusion rod 170 causes the mounting seat 200 to move closer to the outer cylinder 150, causing the buffer spring 180 installed between the outer cylinder 150 and the mounting seat 200 to deform. This, in conjunction with the pressure plate 171 generating the damping force, gradually buffers the clamping force applied to the workpiece, allowing the clamping mechanism to securely fix the workpiece.

[0024] Example 2: Please refer to again Figure 1-5Two mounting bases 200 are provided on one side of the mounting bracket 100. A clamping plate 210 is inserted into one side of the mounting base 200. A rubber pad 211 is adhered to one side of the clamping plate 210. A fixing plate 220 is fixedly connected to one side of the clamping plate 210. Two mounting cylinders 230 are fixedly connected to one side of the fixing plate 220. A tenon 231 is slidably connected to the inner cavity of the mounting cylinder 230. The bottom end of the tenon 231 passes through the mounting cylinder 230 and the fixing plate 220 and extends into the interior of the mounting base 200. A connecting rod 240 is fixedly connected to the other end of the tenon 231. A compression spring 24 is sleeved on the outer side of the connecting rod 240. 1. One end of the connecting rod 240 passes through the mounting cylinder 230 and extends to the outside of the mounting cylinder 230. A pull plate 250 is fixedly connected to one end of the connecting rod 240. The mounting base 200 has a mounting groove 260 inside. A latch 261 is slidably connected to the inner cavity of the mounting groove 260. One end of the latch 261 passes through the mounting groove 260 and a tenon 231 and extends to the inside of the mounting base 200. A lever 270 is fixedly connected to the other end of the latch 261. One side of the lever 270 passes through the mounting groove 260 and extends to the outside of the mounting base 200. A compression spring 280 is embedded in the inner cavity of the mounting groove 260.

[0025] Specifically, by moving the lever 270 to compress the compression spring 280, the latch 261 on the lever 270 is released from fixing the tenon 231 and moves into the mounting groove 260. Then, pulling the pull plate 250 causes the connecting rod 240 to move, causing the tenon 231 to compress the compression spring 241 and move into the mounting cylinder 230. This releases the clamping plate 210 from the mounting base 200, after which the clamp can be... The holding plate 210 is removed from the mounting base 200. When installing the clamp to be used, the clamping plate 210 is inserted into the mounting base 200. Then, the pull plate 250 is released, which resets the compressed spring 241 and pushes the tenon 231 to move and insert it into the mounting base 200. Then, the pull plate 270 is released, which resets the compression spring 280 and pushes the latch 261 to insert into the tenon 231 to fix the tenon 231. The clamping plate 210 is installed on the outside.

[0026] Working principle: The starting motor 120 drives the bidirectional screw 110 to rotate, causing the connecting plate 130 mounted on the bidirectional screw 110 to move the mounting plate 140, so that the clamping mechanism moves closer to clamp the workpiece. After the clamping plate 210 clamps the workpiece, the mounting seat 200 applies pressure to the extrusion rod 170, causing the pressure plate 171 on the extrusion rod 170 to extrude the damping oil 162 in the inner cylinder 160. The damping oil 162 flows through the through hole 172 on the pressure plate 171 to the other side of the pressure plate 171, generating a damping force. At the same time, the movement of the oil extrusion rod 170 causes the mounting seat 200 to move closer to the outer cylinder 150, causing the buffer spring 180 installed between the outer cylinder 150 and the mounting seat 200 to deform. This, together with the pressure plate 171 that generates the damping force, gradually buffers the clamping force applied to the workpiece, so that the clamping mechanism can stably fix the workpiece.

[0027] By moving the lever 270 to compress the compression spring 280, the latch 261 on the lever 270 is released from fixing the tenon 231 and moves into the mounting slot 260. Then, pulling the pull plate 250 causes the connecting rod 240 to move, causing the tenon 231 to compress the spring 241 and move into the mounting cylinder 230. This releases the clamping plate 210 from the mounting base 200, allowing the clamping plate to be removed. 210 is removed from the mounting base 200. When installing the required clamp, the clamping plate 210 is inserted into the mounting base 200. Then, the pull plate 250 is released, which resets the compressed spring 241 and pushes the tenon 231 to move and insert it into the mounting base 200. Then, the pull plate 270 is released, which resets the compression spring 280 and pushes the latch 261 into the tenon 231 to fix the tenon 231. The clamping plate 210 is installed on the outside.
