[0020] The present invention will now be described in detail with reference to specific embodiments:

[0021] like Figures 1 to 7 The diagram shows an automatic upper and lower plate fixed shaft mounting structure for a large copper puller, including a housing 1 and a fixed shaft assembly 2;

[0022] The fixed shaft assembly 2 consists of a bushing 21, a pulley 22, a turntable 23, a rotating shaft 24, an end 25, ball bearings, telescopic cylinders, a bird beak clamping mechanism 3, a push plate 4, and a stop pin 5. The bushing 21 is fixedly installed on the housing 1. The cages of the two ball bearings are fixedly installed inside the bushing 21 at both ends. The rotating shaft 24 is fixedly installed in the rotating body of the ball bearings. The pulley 22 and the turntable 23 are fixedly sleeved on both ends of the rotating shaft 24. The cylinder bodies of the two telescopic cylinders are fixedly installed on the housing 1. The push plate 4 and the stop pin 5 are respectively fixedly installed on the piston rods of the two telescopic cylinders. The turntable 23 is provided with a stop groove 231 that cooperates with the stop pin 5. The end 25 is fixedly installed on the outer end of the rotating shaft 24.

[0023] The bird beak clamping mechanism 3 consists of a first clamping block 31, a second clamping block 32, a movable clamping block 33, a connecting rod 34, a flange 35, a control rod 36, a bolt 37, a T-shaped rod 38, and a stacked spring 39. The first clamping block 31 and the second clamping block 32 are fixedly connected. The first clamping block 31 is fixedly installed on the outer surface of the turntable 23. The flange 35 is fixedly installed on the inner surface of the turntable 23. A U-shaped groove is provided on the flange 35. The control rod 36 is hinged in the middle of the U-shaped groove. The movable clamping block 33 is slidably installed in the through hole 311 of the first clamping block 31. The movable clamping block 33 cooperates with the second clamping block 32 to clamp the bird beak. The copper wire is clamped and fixed. The connecting rod 34 is slidably installed on the turntable 23. The inner end of the connecting rod 34 is fixedly connected to the movable clamp 33. The outer end of the bolt 37 is fixedly connected to the upper end of the control rod 36. The inner end of the bolt 37 is hinged to the connecting rod 34. The T-shaped rod 38 is slidably installed on the turntable 23. The outer end of the T-shaped rod 38 is fixedly provided with an anti-disengagement sleeve. The stacked spring 39 is sleeved and installed on the T-shaped rod 38. The two ends of the stacked spring 39 act on the inner surface of the turntable 23 and the end of the T-shaped rod 38, respectively. The lower end of the control rod 36 always presses against the end of the T-shaped rod 38. The push plate 4 can press against the end of the T-shaped rod 38 to compress the stacked spring 39. The outer ends of the first clamping block 31 and the second clamping block 32 form a beak-shaped inlet. When fixing the copper wire, the turntable 23 rotates until the T-shaped rod 38 and the push plate 4 are coaxial. The telescopic cylinder pushes the push plate 4 to contact the control rod 36, squeezing the T-shaped rod 38 and causing the control rod 36 to rotate. The upper end of the control rod 36 pulls the combination of the connecting rod 34 and the movable clamping block 33, exposing a clamping gap between the movable clamping block 33 and the second clamping block 32. The copper wire is placed in the clamping gap. The piston rod of the telescopic cylinder drives the push plate 4 to retract, releasing the pressure on the control rod 36. Under the action of the spring 39, the T-shaped rod 38 is pushed outward. The T-shaped rod 38 pushes the control rod 36 to rotate. The upper end of the control rod 36 then pushes the combination of the connecting rod 34 and the movable clamping block 33 closer to the second clamping block 32. The copper wire is clamped and fixed by the cooperation of the movable clamping block 33 and the second clamping block 32.

[0024] The pressure contact surface between the lower end of the control rod 36 and the end of the T-shaped rod 38 is a raised structure. The outer end face of the raised structure is set as an arc surface structure. The arc surface structure is in line contact with the end of the T-shaped rod 38 so that the arc surface structure and the T-shaped rod 38 can rotate relatively flexibly.

[0025] The upper part of the outer end of the connecting rod 34 is provided with a T-shaped groove 341 with a top opening. The end of the bolt 37 is embedded in the T-shaped groove 341. The end of the bolt 37 can move within the T-shaped groove 341 to achieve the purpose of hinged installation. Compared with the pin hinged installation method, this structure has the advantage of high structural strength.

[0026] Several positioning pins 232 are arranged in a ring array on the outer end face of the turntable 23. The positioning pins 232 cooperate with the positioning holes on the end face of the coil to form a guiding and positioning function.

[0027] A positioning groove 241 is provided on the outer end face of the end 25. The positioning groove 241 cooperates with the end protrusion of the movable shaft to play a guiding and radial limiting role.

[0028] The movable shaft assembly supports the spool and pushes it closer to the turntable 23. The telescopic cylinder pushes the stop pin 5 into the stop groove 231 to restrict the free rotation of the turntable 23. The copper wire structure is clamped and fixed by the bird beak clamping mechanism 3. The positioning hole of the spool is installed in conjunction with the positioning pin 232 of the turntable. The movable shaft assembly and the fixed shaft assembly 2 are pressed, fixed and supported. The telescopic cylinder drives the stop pin 5 to disengage from the stop groove 231. The pulley 22 is connected to the drive mechanism through belt drive. The rotating shaft 24 and the turntable 23 rotate synchronously with the pulley 22 to perform the winding operation.
