Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0024] See also Figure 1-5 , the utility model provides a technical solution:

[0025] The left and right clamping assemblies 2 are fixed to one side of the top of the workbench 1, and an auxiliary slide rail 3 is fixed to the other side of the top of the workbench 1. The linear slide rail 20 and the auxiliary slide rail 3 are arranged at the same horizontal height. This arrangement improves the stability of the linear slide rail 20 during movement. The connecting arm 22 is located between the linear slide rail 20 and the auxiliary slide rail 3. The left and right clamping assemblies 2 include the linear slide rail 20. The internal rotation of the linear slide rail 20 is connected to the bidirectional screw rod 21. This arrangement does not directly affect the bidirectional screw rod 21 during processing. The two sides of the bidirectional screw rod 21 are threadedly connected to the connecting arm 22. The connecting arm 22 and the auxiliary slide rail 3 are slidably matched. The top of the connecting arm 22 is fixedly connected to the support column 23. The top of the support column 23 is fixedly connected to the clamp seat 24. The inner side of the clamp seat 24 is fixedly connected to the mounting seat 25. The surface of the mounting seat 25 is fixedly connected to the air bag 26. The outer side of the air bag 26 is provided with a protective assembly 27. The protective assembly 27 includes Two connecting seats 271 are fixedly arranged on both sides of the front end surface of the clamping seat 24. The inner side of the connecting seat 271 is rotatably matched with a connecting shaft 272. The surface of the connecting shaft 272 is fixedly connected with an elastic belt 273. There are two elastic belts 273. A protective cloth 274 is elastically connected between each two elastic belts 273. The protective cloth 274 can protect the air bag 26. The surface of the protective cloth 274 is fixedly connected with a rubber anti-slip strip 275. The rubber anti-slip strip 275 is provided with several In particular, several rubber anti-slip strips 275 are arranged in a horizontal direction, which improves the anti-slip performance. The cross-section of the rubber anti-slip strip 275 is elliptical. A pin 276 is inserted into the top of the connecting seat 271. The pin 276 is located above the connecting shaft 272. The bottom end of the connecting seat 271 rotates with the inner wall of the connecting shaft 272. The connecting shaft 272 and the pin 276 are located on the same central axis, which makes it convenient for staff to maintain or replace the protective cloth 274 and ensure the service life of the air bag 26.

[0026] As a further implementation of this solution, one end of the linear slide 20 is fixedly connected to a motor 29, the transmission shaft of the motor 29 passes through the interior of the linear slide 20, and the transmission shaft of the motor 29 is fixedly connected to one end of the bidirectional screw 21, so that the bidirectional screw 21 is provided with power for rotation;

[0027] As a further implementation of this solution, a mounting groove 28 is opened in the middle of the clamping seat 24, and a connecting rod 281 is fixedly connected to the bottom of the mounting groove 28. The connecting rod 281 is set in an "L" shape. The protective cloth 274 is located on the inner side of the connecting rod 281. The protective cloth 274 and the connecting rod 281 are slidably matched. In this way, the middle part of the protective cloth 274 is limited by the connecting rod 281, so that the protective cloth 274 and the air bag 26 are better fitted.

[0028] As a further implementation scheme of this scheme, the top of the support column 23 is fixedly connected to an air pump 261, the air outlet end of the air pump 261 is fixedly connected to a first sealing tube 262, and a second sealing tube 263 is connected through every two adjacent mounting seats 25. The shape of the second sealing tube 263 is a "U" shape, one end of the second sealing tube 263 is fixedly connected to the air inlet end of the air bag 26, and the middle part of the second sealing tube 263 is fixedly connected to one end of the first sealing tube 262. This arrangement facilitates the air pump 261 to inflate the air bag 26.

[0029] Working process: by turning on the motor 29 and controlling the transmission shaft of the motor 29 to rotate forward, the transmission shaft of the motor 29 drives the bidirectional screw 21 to rotate synchronously, so that the two connecting arms 22 move relative to each other. When the connecting arms 22 move, they drive the support column 23 and the clamping seat 24 to rotate synchronously, and control the distance between the two clamping seats 24. By turning on the two air pumps 261, the air pump 261 delivers air to the first sealing tube 262 through the air outlet, and then transmits it to the air bag 26 through the second sealing tube 263. The air bags 26 on both sides expand under the action of air and contact the piston surface through the protective cloth 274 to achieve clamping and limiting of the piston. This design avoids damage to the piston caused by placement angle deviation. When the air pump 261 is turned off, the air bag 26 is exhausted through the air outlet under the action of air pressure.

[0030] The protective cloth 274 set by the elastic band 273 has good elasticity and can fit better with the piston. The protective cloth 274 can protect the surface of the air bag 26, and also reduce the damage of the sharp edge of the piston to the surface of the air bag 26, prevent air leakage caused by cuts, and increase the service life of the air bag 26. The rubber anti-slip strip 275 set in the horizontal direction improves the anti-slip property of the contact with the piston, avoiding the accidental drop of the piston. By removing the pin shaft 276, the pin shaft 276 no longer limits the top end of the connecting shaft 272, and the connecting shaft 272 can be disengaged from the connecting seat 271. The protective cloth 274 can be removed from the inner side of the connecting rod 281 by moving upward, which can facilitate the staff to maintain or replace the protective cloth 274.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
