The limiting column 37 is symmetrically fixed It is fixedly installed on the side end surface of the second support seat 33 facing the first support seat 29, and the limit column 37 is slidably installed inside the first support seat 29, the return spring 36 is installed outside the limit column 37, and the two ends of the return spring 36 are in extrusion contact with the outer walls of the first support seat 29 and the second support seat 33, the extrusion push frame 32 is fixedly installed on the upper part of the side end of the second sliding adjustment plate 28 away from the second support seat 33, two extrusion limit rings 27 are provided, and the extrusion limit rings 27 are fixedly connected to the upper end of the support connecting plate 35.

[0031] The bottom end of the sliding movable plate 25 is slidably clamped on the limiting conveying plate 12, the extrusion limiting ring 27 is located inside the metal ring 4, and the metal ring 4 is clamped between the extrusion limiting ring 27 and the limiting outer frame 23, one end of the pulling control rope 7 is fixedly connected to the bottom end of the movable pull plate 13, and the other end of the pulling control rope 7 is fixedly connected to the bottom end of the sliding push rod 19, the electric hydraulic push rod 2 is fixedly installed on the support fixing frame 1, and the front end of the electric hydraulic push rod 2 is fixedly connected to the auxiliary support mounting plate 26 located on the outside.

The extrusion control wheel 18 is adapted to the extrusion groove set in the middle of the extrusion push frame 32, which facilitates the extrusion control wheel 18 to stably connect the extrusion push frame 32 during the movement.

[0033] The bottoms of both ends of the sliding movable plate 25 are arranged in an inclined shape, and pressure sensors 38 are fixedly installed on the bottom ends of the inclined parts of the two ends of the sliding movable plate 25. The inclined parts can be squeezed with the inclined upper end surface of the positioning extrusion sliding block 17 to make the positioning extrusion sliding block 17 slide. The size and value of the extrusion force between the sliding movable plate 25 and the positioning extrusion sliding block 17 can be detected in real time through the pressure sensor 38. A rubber sleeve is fixedly installed on the outside of the extrusion limit ring 27 by bolts, so that the metal ring 4 is squeezed and fixed firmly, and a regulating electric hydraulic push rod 39 is fixedly installed in the middle of the inner end of the limiting cross plate 20.

[0034] Working principle: when the metal ring 4 needs to be transported to a specified distance and position during processing, first, the extrusion and pushing frame 32 is squeezed by starting and regulating the electric hydraulic push rod 39 to make the second sliding adjustment plate 28 slide along the sliding movable plate 25. At this time, the second sliding adjustment plate 28 can make the rotating adjustment plate 30 rotate through the connecting control arm 31. The rotating rotating adjustment plate 30 can pull the first sliding adjustment plate 24 to slide along the sliding movable plate 25 through the return spring 36. At this time, the first sliding adjustment plate 24 and the second sliding adjustment plate 28 can achieve synchronous sliding toward the middle of the sliding movable plate 25, and the return spring 36 can be compressed by the second support seat 33 and the first support seat 29. At this time, The second support seat 33 and the first support seat 29 that move by using the supporting connecting plate 35 can drive the two extrusion limit rings 27 to move a specified distance toward the middle of the sliding adjustment block 15. At this time, the gap between the extrusion limit ring 27 and the inner part of the limit outer frame 23 increases, so that it is convenient to put the metal ring 4 between the limit outer frame 23 and the extrusion limit ring 27, and then remove the extrusion force of the regulating electric hydraulic push rod 39 on the extrusion push frame 32. At this time, the reset spring 36 is reset. Under the supporting elastic force of the reset spring 36, the second support seat 33 and the second sliding adjustment plate 28 as well as the first support seat 29 and the first sliding adjustment plate 24 are synchronously slid and reset along the sliding moving plate 25, and at this time, the extrusion limit ring 27 is driven toward the limit outer frame 2 3 is moved, so that the metal ring 4 is firmly fixed between the limiting outer frame 23 and the extrusion limiting ring 27, and then the metal ring 4 is conveyed along the limiting conveying plate 12 in the direction and distance as required, and the positioning extrusion sliding block 17 at the specified position and distance is automatically supported and raised by adjusting the electric hydraulic push rod 16, so that the inclined part of the positioning extrusion sliding block 17 slides out from the inside of the limiting sliding slot 11 set on the limiting conveying plate 12, and then the electric hydraulic push rod 2 is started to push and pull the auxiliary support mounting plate 26 through the electric hydraulic push rod 2 to control the sliding moving plate 25 to slide along the limiting conveying plate 12 to the specified direction. When the fixing conveying mechanism 3 as a whole slides and moves together with the metal ring 4 during the sliding conveying process The front end of the plate 25 will be squeezed and contacted with the upper end of the positioning and squeezing sliding block 17 which is set at an angle, and because the upper end of the positioning and squeezing sliding block 17 is smoothly set at a 45° angle, and the bottoms of both ends of the sliding movable plate 25 are set at an angle, the sliding movable plate 25 will squeeze the positioning and squeezing sliding block 17 so that the positioning and squeezing sliding block 17 slides downward along the limiting sliding slot 11 provided on the limiting conveying plate 12, and when the squeezing force is greater than the supporting force of the first supporting spring 14, the positioning and squeezing sliding block 17, the adjusting electric hydraulic push rod 16 and the sliding adjusting block 15 all slide downward, and at this time, the sliding adjusting block 15 sliding downward can control the moving pull plate 13 to slide downward, and the moving pull plate 13 sliding downward will pull the pulling control rope 7,Since the other end of the pull control rope 7 is fixedly connected to the bottom of the end of the sliding push rod 19 through the limit plate 8 and the limit barrier of the rotating shaft 9, the pull control rope 7 can pull the sliding push rod 19 to slide forward along the limit horizontal plate 20. At this time, the sliding push rod 19 drives the extrusion control wheel 18 to slide forward, and when the extrusion control wheel 18 slides to a specified distance, the extrusion control wheel 18 is in contact with the extrusion push frame 32. Therefore, the extrusion control wheel 18 can push the extrusion push frame 32 and the second sliding adjustment plate 28 to slide along the sliding moving plate 25. At this time, the sliding second sliding adjustment plate 28 is pushed and pushed by the extrusion control wheel 18. The node plate 28 can drive the first sliding adjustment plate 24 to slide synchronously along the sliding movable plate 25 toward the middle of the sliding movable plate 25, so as to control the sliding of the extrusion limit ring 27 and continuously compress the reset spring 36. At this time, the distance between the extrusion limit ring 27 and the limit outer frame 23 increases, so that the metal ring 4 is locked and fixed between the limit outer frame 23 and the extrusion limit ring 27 and then movably placed between the limit outer frame 23 and the extrusion limit ring 27. At this time, the pressure sensor 38 installed at the front end of the sliding movable plate 25 detects that the sliding movable plate 25 is in contact with the positioning extrusion sliding plate 25. The size of the extrusion force between the blocks 17, when the extrusion force meets the specified value when the metal ring 4 changes from a fixed state to an active state, the detected information is transmitted to the inside of the external control device through a wire or wireless transmission, and the electric hydraulic push rod 2 is controlled by the external control device to stop running, so the metal ring 4 stops conveying and moving, so that the metal ring 4 can be conveyed to a specified distance and position in a specified direction along the limiting conveying plate 12 through the clamping conveying mechanism 3, and during the conveying process, the metal ring 4 is in an extruded locked fixed state, and automatically becomes an active state after being conveyed to the specified position, which is convenient for the external clamping device to clamp the metal ring 4 for processing, and the metal ring 4 can be conveyed to the specified position by controlling the positioning extrusion sliding block 17 at the specified position to rise. When the metal ring 4 is conveyed to the specified position during the use of the device, it is only necessary to raise the positioning extrusion sliding block 17 at the specified position by adjusting the electric hydraulic push rod 16 to expose it from the inside of the limiting sliding card slot 11 set on the limiting conveying plate 12, and when the metal ring 4 is conveyed to the specified position by the clamping conveying mechanism 3, it can automatically change from a locked fixed state to an active state. ,
