[0018] 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: an automatic chuck alignment device, including a ring body 1, a connecting plate 2 installed on the inner surface of the ring body 1, a braking mechanism 3 provided on the inner surface of the ring body 1, a support mechanism 4 provided on the inner surface of the ring body 1, and a cylinder 5 fixedly connected to the outer surface of the ring body 1.

[0020] The braking mechanism 3 includes a movable column 301, an air chamber 302, an air supply channel 303, a fixing groove 304, a clamping block 305, a movable rod 306, and a fixing column 307. The movable column 301 is slidably connected to the inner surface of the ring body 1. The air chamber 302 is formed on the inner surface of the ring body 1. The air supply channel 303 is formed on one side surface of the ring body 1. A fixing groove 304 is formed on one side surface of the connecting plate 2. A clamping block 305 is slidably connected to one side surface of the connecting plate 2. A movable rod 306 is fixedly connected to one side surface of the clamping block 305. A fixing column 307 is fixedly connected to one side surface of the movable rod 306. The mechanism is connected via the movable column 301, air chamber 302, air supply channel 303, fixing groove 304, clamping block 305, and movable rod 307. The arrangement of 06 and the fixed column 307 allows for clamping operations via the clamping block 305. First, the cylinder 5 delivers gas through the air supply channel 303 inside the annular body 1 to the air chamber 302. Then, the moving column 301 moves up and down under the action of the gas. The moving rod 306 then moves the clamping block 305 under the push of the moving column 301. The clamping block 305 can then move on the connecting plate 2. When the fixed column 307 is pushed outward, the clamping block 305 moves outward away from the center of the connecting plate 2. Conversely, when the fixed column 307 moves inward through the action of the moving column 301, the clamping block 305 moves inward toward the center of the connecting plate 2 under the action of the fixed groove 304.

[0021] Furthermore, the movable column 301 and the ring 1 form a sliding structure, which allows for better clamping by setting the movable column 301.

[0022] Furthermore, the clamping blocks 305 are evenly distributed on the outer surface of the connecting plate 2, and the clamping blocks 305 can be better fixed.

[0023] Furthermore, the support mechanism 4 includes a ring 401, a support column 402, a connecting ring 403, a connecting key 404, a sliding column 405, a fixed ring 406, and a sliding groove 407. The ring 401 is mounted on the inner surface of the ring body 1, and the support column 402 is mounted on the inner surface of the ring 401. The connecting ring 403 is slidably connected to one side surface of the support column 402, and the connecting key 404 is fixedly connected to one side surface of the connecting ring 403. The sliding column 405 is rotatably connected to the inner surface of the connecting key 404, and the fixed ring 406 is slidably connected to the outer surface of the sliding column 405. The ring 401... The arrangement of 401, support column 402, connecting ring 403, connecting key 404, sliding column 405, fixed ring 406, and sliding groove 407 is such that when it is necessary to support the inside of the ring body 1, by rotating the fixed ring 406, the sliding column 405 in the sliding groove 407 opened in the fixed ring 406 moves. Then the sliding column 405 will move in the sliding groove 407, thereby causing the connecting key 404 to drive the connecting ring 403 to move away from the center of the fixed ring 406. Then the support column 402 on the outside of the connecting ring 403 will apply an upward force, thereby supporting the ring 401.

[0024] Furthermore, the support columns 402 are evenly distributed on one side surface of the ring 401, and the connecting ring 403 and the fixed ring 406 form a rotating structure through the sliding column 405. The support columns 402 provide better support.

[0025] Furthermore, a sliding groove 407 is provided on one side surface of the fixing ring 406, which allows for better rotation.

[0026] Working principle: When clamping is required by the clamping block 305, the cylinder 5 first delivers gas through the air supply channel 303 inside the annulus 1 to the air chamber 302. Then, the moving column 301 moves up and down under the action of the gas. The moving rod 306 then moves the clamping block 305 under the push of the moving column 301. The clamping block 305 can then move on the connecting plate 2. When the fixed column 307 pushes outward, the clamping block 305 moves outward away from the center of the connecting plate 2. Conversely, when the fixed column 307 moves inward under the action of the moving column 301, the clamping block 305 moves inward toward the center of the connecting plate 2 under the action of the fixed groove 304. When clamping is required via clamping block 305, the cylinder 5 first delivers gas through the gas supply channel 303 inside the annulus 1 to the air chamber 302. Then, the moving column 301 moves up and down under the action of the gas. The moving rod 306 then moves the clamping block 305 under the push of the moving column 301. The clamping block 305 can then move on the connecting plate 2. When the fixed column 307 pushes outward, the clamping block 305 moves outward away from the center of the connecting plate 2. Conversely, when the fixed column 307 moves inward through the action of the moving column 301, the clamping block 305 moves inward toward the center of the connecting plate 2 under the action of the fixed groove 304.

[0027] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
