[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1.

[0015] 2. By setting a swing auxiliary unit, when the output end of the first hydraulic cylinder drives the U-shaped slide to drive the swing block to move horizontally, the connecting block contacts the roller, and the connecting block drives the swing block to rotate through the rotating shaft under the push of the roller, so that the swing block can rotate to a vertical position. When the chain becomes loose during use, the chain will be slightly concave downward. During the rotation of the swing block, the power wheel will push the slightly offset fixed rod upward, so that the slightly loose chain can be pushed to reset, so that the U-shaped hanging ring can always maintain its initial state, thereby improving the accuracy of the U-shaped hanging ring loading, so that the subsequent opening of the U-shaped hanging ring is more accurate;

[0016] 3. By setting a clamping auxiliary part, when the swing block rotates to the vertical position, the output end of the first hydraulic cylinder continues to pull the U-shaped slide seat to drive the swing block to move horizontally. When the slide bar is against the resistance of the third fixed seat in the groove, the slide bar will slide relative to the outer wall of the swing block, so that the clamping blocks are always located on both sides of the fixed rod, and then the swing block contacts the cylinder through the inclined groove on the inner side of the power rod during the process of continuing to move horizontally, pushing the cylinder to drive the clamping blocks to approach the fixed rod. When the cylinder separates from the inclined groove and contacts with the straight groove, the two clamping blocks are clamped on the outer wall of the fixed rod, thereby clamping the fixed rod, thereby improving the stability of the U-shaped hanging ring when opening a hole, avoiding the chain shaking caused by the vibration force of the U-shaped hanging ring during the hole opening process, thereby further improving the accuracy of the U-shaped hanging ring opening.

[0032] First, the U-shaped hanging ring 4 can be grasped and placed inside the placing seat 311 by manual or robotic arm. The controller controls the first driving motor 302 to start and stop intermittently. The output end of the first driving motor 302 drives the rotating roller 304 to drive the spur gear 303 to rotate, thereby driving the chain 305 to drive multiple U-shaped hanging rings 4 to be intermittently fed to one side of the first support 2. When the U-shaped hanging ring 4 stops on one side of the first support 2, the controller controls the first hydraulic cylinder 504 to start intermittently. The output end of the first hydraulic cylinder 504 drives the U-shaped sliding seat 502 to drive the swinging block 505 to move horizontally. When the driving wheel 512 contacts the convex block 506, it pushes the convex block 506 to drive the U-shaped hanging ring 4 to move towards the first support 2 through the first slider 309 and the placing seat 311. When the first hydraulic cylinder 504 stops operating, the U-shaped hanging ring 4 moves to both sides of the first support 2.

[0035] Embodiment 2

[0036] The clamping connection assembly 11 includes an arc-shaped baffle 1106 fixedly connected to the top of the placement seat 311. The top of the arc-shaped baffle 1106 is matched with the U-shaped surface inside the U-shaped hanging ring 4. An arc-shaped clamping seat 1104 is fixedly connected to the top of the arc-shaped baffle 1106. A third slider 1107 is slidably connected to the inside of the arc-shaped baffle 1106. An arc-shaped clamping block 1105 is fixedly connected to the top of the third slider 1107. A pulling rod 1103 is fixedly connected to the inside of the third slider 1107.

[0037] The traction rope 1102 is initially in a relaxed state. When the first slider 309 drives the U-shaped hanging ring 4 to move a certain distance in the direction of the first support 2, the traction rope 1102 will be straightened. When the first slider 309 continues to move, it will pull the pulling rod 1103 through the traction rope 1102 to drive the arc-shaped clamping block 1105 to move in the direction of the U-shaped hanging ring 4. When the first slider 309 moves to the maximum position, the arc-shaped clamping block 1105 can push the U-shaped hanging ring 4 to fit against the outer wall of the arc-shaped clamping seat 1104 and form a fixation for the U-shaped hanging ring 4 with the arc-shaped clamping seat 1104. In this way, the device can automatically calibrate and clamp the U-shaped hanging ring 4 without manual operation by the staff, thereby improving the processing efficiency of the U-shaped hanging ring 4.

[0038] Embodiment 3

[0040] The bottom of the fixed rod 307 is flush with the bottom of the supporting block 308. When the output end of the first hydraulic cylinder 504 drives the U-shaped slide 502 to drive the swing block 505 to move horizontally, the connecting block 509 contacts the roller 508. Under the push of the roller 508, the connecting block 509 drives the swing block 505 to rotate through the rotating shaft 510, so that the swing block 505 can rotate to a vertical position. When the chain 305 becomes loose during use, the chain 305 will be slightly concave downward. During the rotation of the swing block 505, the power wheel 512 will push the slightly offset fixed rod 307 to move upward, thereby pushing the slightly loosened chain 305 to reset, so that the U-shaped hanging ring 4 can always maintain its initial state, thereby improving the accuracy of feeding the U-shaped hanging ring 4, so that the subsequent hole opening of the U-shaped hanging ring 4 can be more accurate.

[0041] Example 4

A second connecting spring 611 is installed between the two second sliders 610. One end of the second slider 610 extends to the outer wall of the connecting seat 603 and is fixedly connected to the clamping block 602.

[0043] When the swing block 505 rotates to the vertical position, when the output end of the first hydraulic cylinder 504 continues to pull the U-shaped slide seat 502 to drive the swing block 505 to move laterally, when the slide rod 604 abuts against the groove 605 and is resisted by the third fixed seat 503, the slide rod 604 will slide relative to the outer wall of the swing block 505, so that the clamping block 602 is always located on both sides of the fixed rod 307. Furthermore, when the swing block 505 continues to move laterally, under the action of the second inclined groove 609 inside the power rod 601, it contacts the cylinder 608, and pushes the cylinder 608 to drive the clamping block 602 to approach the fixed rod 307. When the cylinder 608 separates from the second inclined groove 609 and contacts the straight groove 607, the two clamping blocks 602 clamp on the outer wall of the fixed rod 307, thereby clamping the fixed rod 307, so as to improve the stability of the U-shaped hanging ring 4 during the hole opening process, avoid the chain 305 from shaking due to the vibration force during the hole opening process of the U-shaped hanging ring 4, and further improve the accuracy of the hole opening of the U-shaped hanging ring 4.
