Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 - 5 , the present utility model provides a technical solution:

[0028] Embodiment 1:

[0029] A pneumatic chuck that can be opened and closed at multiple angles includes an adjustment base 1. A horizontal adjustment structure is installed on the top of the adjustment base 1, a longitudinal adjustment structure is installed on the bottom of the adjustment base 1, and a clamping structure is installed at the bottom of the longitudinal adjustment structure.

[0030] The longitudinal adjustment structure includes an adjustment unit and an installation and connection unit. The adjustment unit includes a first movable part 203. A movable plate 204 is installed at the bottom of the first movable part 203. Second movable parts 205 are installed at the left and right ends of the top surface of the movable plate 204. A cylinder 206 is connected to the top of the second movable part 205. A third movable part 207 is installed at the top of the cylinder 206. The installation and connection unit includes a rotating disk 201. A connecting rod 202 is installed in the middle of the bottom surface of the rotating disk 201.

[0031] The bottom end of the connecting rod 202 is connected to the middle of the top surface of the first movable part 203. The top surface of the third movable part 207 is connected to the bottom surface of the rotating disk 201. The first movable part 203, the second movable part 205, and the third movable part 207 are movable hinge parts.

[0032] The horizontal adjustment structure includes an electric push rod 101. The output end of the electric push rod 101 is connected to a push plate 102. A rack 103 is connected to the front of the push plate 102. A limit block 104 is installed on the bottom surface of the rack 103. A transmission part 105 is connected to the front of the rack 103. The bottom surface of the electric push rod 101 is detachably connected to the top surface of the adjustment base 1. The bottom surface of the push plate 102 is slidably connected to the top surface of the adjustment base 1. The outer surface of the limit block 104 is slidably connected to the inner wall of the convex chute opened on the top surface of the adjustment base 1. The bottom end of the transmission part 105 is fixedly connected to the middle of the top surface of the rotating disk 201.

[0033] Through the settings of the longitudinal adjustment structure and the horizontal adjustment structure, by controlling the two cylinders 206, the longitudinal angle of the movable plate 204 can be controlled by using the first movable part 203, the second movable part 205, and the third movable part 207. By driving the transmission of the rack 103 and the transmission part 105 with the electric push rod 101, the rotating disk 201 can be driven to rotate for horizontal angle adjustment.

[0034] When it is necessary to adjust the horizontal angle of the pneumatic clamp, start the electric push rod 101 to drive the push plate 102 to displace, thereby driving the rack 103 to displace. At the same time, use the sliding of the limit block 104 inside the convex groove opened on the top surface of the adjusting seat 1 to maintain the stability of the displacement of the rack 103. Utilize the meshing connection between the rack 103 and the transmission member 105 to make the rack 103 drive the gear to rotate. When the gear rotates, it drives the rotating disk 201 to rotate through the rotating shaft, thereby realizing the adjustment of the horizontal angle. When it is necessary to adjust the longitudinal angle, start the cylinder 206 to push the second movable member 205 and one end of the movable plate 204 to displace, so that the movable plate 204 rotates around the bottom end of the connecting rod 202 by using the first movable member 203, and at the same time, make the cylinder 206 generate an angle inclination by using the third movable member 207 and the second movable member 205, thereby realizing the adjustment of the angle of the pneumatic clamp 301 driven by the inclination of the movable plate 204.

[0035] Embodiment 2:

[0036] On the basis of Embodiment 1, the clamping structure includes a pneumatic clamp 301. A clamping plate 302 is installed at the bottom of the pneumatic clamp 301.

The top of the pneumatic clamp 301 is connected to the middle part of the bottom surface of the movable plate 204. An anti-slip layer is installed on one side where the two anti-slip plates 304 approach each other.

[0037] Through the setting of the clamping structure, when using the pneumatic clamp 301 to drive the two clamping plates 302 to clamp, due to the installation of the damping rod 303, it can effectively prevent excessive clamping force from damaging the product. By using the anti-slip layer on the surface of the anti-slip plate 304, the stability during the clamping process can be ensured.

[0038] During the clamping process, through the connection of an air pump, an air pipe, etc. to the pneumatic clamp 301, the pneumatic clamp 301 drives the clamping plate 302 to open and close for clamping or loosening. During the clamping process, the anti-slip plate 304 abuts against the product. By using the anti-slip layer on the surface of the anti-slip plate 304, the stability during the clamping process can be effectively ensured. When the two clamping plates 302 approach each other to complete the clamping operation, the anti-slip plate 304 and the clamping plate 302 squeeze the damping rod 303, thereby using the damping rod 303 to buffer the squeezing force during clamping and prevent excessive clamping force from damaging the product.
