[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] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a double-cylinder opening and closing caliper fixing mechanism, including a mounting plate 1, a caliper body 102 and a slide rail 2. A support block 101 is connected to one side of the mounting plate 1, and a set of caliper bodies 102 are provided on the upper side of the mounting plate 1.

[0023] The mounting plate 1 is symmetrically connected to the upper side of the slide rails 2. The mounting plate 1 is symmetrically provided with sliding grooves 202 inside. The outer sides of the two slide rails 2 are inserted into the sliding plate 201. The outer side of the sliding plate 201 is connected to the connecting frame 203. The outer side of the connecting frame 203 is inserted through the sliding groove 202. The bottom of the connecting frame 203 is symmetrically connected to the connecting block 204. The two connecting blocks 204 are provided with a mounting block 205 on one side. The side of the two mounting blocks 205 away from the connecting block 204 is connected to the pushing cylinder 206. The top of the two pushing cylinders 206 is connected to the mounting plate 1. The two pushing cylinders 206, the connecting frame 203, the connecting block 204 and the mounting block 205 are all mirrored on the bottom of the mounting plate 1.

[0024] In specific implementation, to improve the stability of the two caliper bodies 102 when they are engaged, a set of push cylinders 206 installed at the bottom of the mounting plate 1 is activated. The push cylinders 206 retract and drive the connecting block 204, the connecting frame 203 connected to the inner side of the connecting block 204, and the sliding plate 201 connected to the upper side of the connecting frame 203 to move along the sliding groove 202 and the slide rail 2, respectively. This causes the caliper body 102 connected to the sliding plate 201 to move towards the caliper body 102 on the upper side of the support block 101 for clamping. This double-cylinder opening and closing caliper fixing mechanism uses two sets of cylinders to drive the caliper body 102 to move, so that the pulling force on the caliper body 102 is more evenly distributed. This, in turn, cooperates with the slide rail 2 and the sliding groove 202 to improve the stability of the caliper body 102 on the upper side of the sliding plate 201 when it moves, thereby effectively reducing the failure rate of the caliper body 102.

[0025] See Figures 3-4 It can be seen that both mounting plates 1 are rotatably connected to limit brackets 3, and both connecting blocks 204 have mounting grooves 303 and guide grooves 302 inside. The outer sides of both limit brackets 3 are inserted into the mounting grooves 303. The guide grooves 302 are symmetrically arranged on both sides of the mounting grooves 303. Limit blocks 301 are symmetrically connected to the outer sides of the limit brackets 3, and the insertion dimensions of the limit blocks 301 match the insertion dimensions of the guide grooves 302. A screwing block 304 is connected to the side of the limit bracket 3 away from the mounting block 205. The bottom of the limiting block 301 is inserted into the clamping bracket 305. The outer side of the clamping bracket 305 is elastically connected to the connecting block 204 through the return spring 306. The two caliper bodies 102 are symmetrically provided with guide grooves 4 inside. The upper side of the support block 101 and the sliding plate 201 are symmetrically connected with guide posts 401. The outer side of multiple guide posts 401 is inserted into the guide grooves 4 inside the caliper body 102. The bottom of the two caliper bodies 102 is connected to the support block 101 and the sliding plate 201 respectively through the limiting screws 402.

[0026] In practice, to facilitate the subsequent maintenance of the cylinder 206, the maintenance personnel loosen the connection between the cylinder 206 and the mounting plate 1, then pull down the snap-fit ​​bracket 305 on the lower side of the connecting block 204. The snap-fit ​​bracket 305 moves down until it is disengaged from the bottom limit block 301 of the limit frame 3. The maintenance personnel then rotate the screwing block 304 on one side of the limit frame 3. The screwing block 304 drives the limit frame 3 to rotate along the mounting groove 303, rotating the limit block 301 connected to the limit frame 3 to the guide groove 302. At this time, the cylinder 206 can be moved to easily remove it from the connecting block 204.

[0027] After the maintenance is completed, pull the clamping bracket 305 again, and insert the limiting bracket 3 and the limiting block 301 into the mounting groove 303 and the guide groove 302 respectively. Then, adjust the limiting block 301 to a vertical position by turning the block 304. At this time, release the clamping bracket 305, and the clamping bracket 305 can pop up under the action of the return spring 306 and insert into the limiting block 301 to limit the limiting bracket 3, thus completing the connection between the connecting block 204 and the mounting block 205. At the same time, the two caliper bodies 102 are connected by the guide groove 4 and the guide post 401, and a single limiting screw 402 is connected to the support block 101 and the sliding plate 201 respectively, which makes it easy to replace the caliper body 102. The installation method of the mounting block 205 and the connecting block 204 on the side of the pushing cylinder 206 is simple and convenient, which facilitates the maintenance of the pushing cylinder 206.

[0028] In summary, when using this dual-cylinder opening and closing caliper fixing mechanism, first place the object to be clamped on the upper side of the mounting plate 1, then start the push cylinder 206. The push cylinder 206 drives the connecting block 204, connecting frame 203 and sliding plate 201 to move along the sliding groove 202 and slide rail 2 respectively through the mounting block 205 on one side. This causes the caliper body 102 connected to the sliding plate 201 to move towards the upper side of the support block 101 for clamping. The contents not described in detail in this description are existing technologies known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
