A motor 104 is fixedly mounted on the mounting frame 100. A drive gear 105 is fixedly installed at the output end of the motor 104, and a driven gear 106 is fixedly installed on the other side of the slewing support bearing 102. The drive gear 105 and the driven gear 106 mesh with each other. The first cylinder 200 and the second cylinder 301 are used as the source of clamping force, which can avoid damage to the workpiece due to excessive clamping force. At the same time, the second synchronous rotating shaft 305, the second synchronous rotating rod 306, and the second synchronous fixed rotating shaft 307 form a synchronization mechanism to ensure that the clamping distance on both sides is consistent and to avoid the midpoint offset of the device. Meanwhile, the device can be adjusted in angle under the drive of the motor 104, which makes it convenient for the equipment to clamp the workpiece at different angles and change the orientation of the workpiece after clamping.

[0026] Two pairs of first mounting brackets 202 are fixedly mounted on the rotating work plate 103. A first slide rod 203 is fixedly mounted between the two first mounting brackets 202. Two first synchronizing rods 204 are slidably mounted on the first slide rod 203. The first synchronizing rods 204 are fixedly mounted on the first clamping roller 201. The first clamping roller 201 at the output end of the first cylinder 200 drives the first synchronizing rods 204 to slide on the first slide rods 203. The first synchronizing rods 204 are restricted by the first slide rods 203 and can only move in a fixed direction.

[0027] Each of the two first synchronizing rods 204 is rotatably mounted with a first synchronizing shaft 205.

A first fixed rotating shaft 207 is rotatably mounted on the first synchronizing rotating rod 206, and the first fixed rotating shaft 207 is fixedly mounted on the second mounting bracket 300. The movable first synchronizing rod 204 drives the first synchronizing shaft 205 and the first synchronizing rotating rod 206 to rotate, and the first synchronizing rotating rod 206 rotates at the midpoint of the first fixed rotating shaft 207.

[0028] A second slide rod 303 is fixedly installed between the second mounting brackets 300. A second synchronizing rod 304 is slidably installed on the second slide rod 303. The second synchronizing rod 304 is fixedly installed on the second clamping roller 302. The second clamping roller 302 drives the second synchronizing rod 304 to slide on the second slide rod 303. The movable second synchronizing rod 304 is restricted by the second slide rod 303 and can only be used within a fixed range.

[0029] Each of the two second synchronizing rods 304 is rotatably mounted with a second synchronizing shaft 305.

The movable second synchronizing rods 304 drive the second synchronizing rotating shafts 305 and 306 to rotate. The second synchronizing rotating rod 306 rotates at the midpoint of the second synchronizing fixed rotating shaft 307. The second synchronizing shafts 305, 306, and 307 form a synchronizing mechanism to ensure that the clamping distance on both sides remains consistent, preventing the midpoint of the device from shifting.

[0030] An air inlet annular flange 400 is fixedly installed on the side of the rotating working disk 103. The air inlet annular flange 400 has an air inlet hole 401 and an air outlet 402.

[0032] Working principle:

[0033] When using this device, the motor 104 needs to be started first. The output end of the motor 104 drives the drive gear 105 to rotate. The rotating drive gear 105 drives the slewing support bearing 102 to rotate within the bushing 101 through the driven gear 106. The rotating slewing support bearing 102 drives the rotating working disk 103 on the other side to rotate, so that the device can be adjusted in angle under the drive of the motor 104. This facilitates the device to clamp workpieces at different angles and change the orientation of the workpiece after clamping. In the clamping part, the first cylinder 200 and the second cylinder 301 are started. The first clamping roller 201 at the output end of the first cylinder 200 drives the first synchronous rod 204 to slide on the first slide rod 203. The first synchronous rod 204 is restricted by the first slide rod 203 and can only move in a fixed direction. The moving first synchronous rod 204 drives the first synchronous rotating shaft 205 and the first synchronous rotating rod 206 to rotate. The first synchronous rotating rod 206 rotates at the midpoint of the first fixed rotating shaft 207. As for the second cylinder 301, the second clamping roller... Shaft 302 drives the second synchronizing rod 304 to slide on the second slide rod 303. The movable second synchronizing rod 304 is restricted by the second slide rod 303 and can only be used within a fixed range. The movable second synchronizing rod 304 drives the second synchronizing rotating shaft 305 and the second synchronizing rotating rod 306 to rotate. The second synchronizing rotating rod 306 rotates at the midpoint of the second synchronizing fixed rotating shaft 307. The second synchronizing rotating shaft 305, the second synchronizing rotating rod 306, and the second synchronizing fixed rotating shaft 307 form a synchronizing mechanism to ensure... To ensure that the clamping distances on both sides remain consistent and to avoid any deviation of the midpoint of the device, the first cylinder 200 and the second cylinder 301 are reinforced by the first reinforcing rod 208 and the second reinforcing rod 308, respectively, to ensure connection with the rotating working plate 103. Gas is supplied to the first cylinder 200 and the second cylinder 301 through the air inlet 401 and the air outlet 402. The gas is supplied to the first cylinder 200 and the second cylinder 301 through the gas supply connector 1 405 and the gas supply connector 2 406.
