In combination with the above embodiment, the working process of the present application is as follows:
in the initial state, the four positioning rods 180 are abutted against each other under the action of the first spring 170, and the abutment points of the four positioning rods 180 are located at the axis of the fixed ring 110. In operation, a workpiece is placed in the fixed ring 110, and is positioned by the four positioning rods 180, so that the axis of the workpiece is in the same straight line with the axis of the fixed ring 110. The two sides of each positioning rod 180 are provided with a first adjusting rod 220 and a second adjusting rod 230 in parallel, the lengths of the first adjusting rod 220 and the second adjusting rod 230 are equal to the lengths of the positioning rods 180, the sizes of a first friction wheel 260 arranged on the first adjusting rod 220 and a second friction wheel 270 arranged on the second adjusting rod 230 are consistent with the sizes of rotating wheels 280 arranged at the inner ends of the positioning rods 180, one ends of the first adjusting rod 220 and the second adjusting rod 230 are in sliding connection with the guide plate 140, and when the inner ends of the positioning rods 180 are in butt joint with the side walls of workpieces, the first adjusting rod 220 and the second adjusting rod 230 are simultaneously in butt joint with the side walls of the workpieces.
By simultaneously starting the four motors 250 mounted on the mounting shell 130, the power output shafts of the motors 250 simultaneously drive the four screws 240 to rotate, and the rotation of the four screws 240 simultaneously pushes the driving rod 210 to move inwards along the radial direction of the fixed ring 110, since the inner end of the driving rod 210 is connected with the end of the first adjusting rod 220 far away from the guide plate 140 through the first pushing rod 310, the inner end of the driving rod 210 is connected with the end of the second adjusting rod 230 far away from the guide plate 140 through the second pushing rod 320, the first pushing rod 310 is fixedly connected with the first gear 330, the second pushing rod 320 is fixedly connected with the second gear 340, and the first gear 330 is in meshed connection with the second gear 340. In the process that the driving rod 210 is driven by the screw 240 to slide inward along the radial direction of the fixing ring 110, the angle between the first and second pushing rods 310 and 320 increases, the first and second adjusting rods 220 and 230 are far away from each other along the length direction of the guide plate 140, and the first and second adjusting rods 220 and 230 slide along the length direction of the guide plate 140 by the same distance under the action of the first and second gears 330 and 340.

If the distance between the first adjusting rod 220 and one end of the workpiece reaches the first preset value, but the distance between the second adjusting rod 230 and the other end of the workpiece does not reach the first preset value, the output signal of the first ultrasonic range finder 410 controls the first cylinder 510 to start, the first cylinder 510 drives the first telescopic rod 540 to extend, the first locking block 520 fixedly arranged at the other end of the first telescopic rod 540 gradually approaches the first friction wheel 260, and the first friction wheel 260 is fixedly provided with the first locking wheel 530, so that the first friction wheel 260 stops rotating when the first locking block 520 abuts against the first locking wheel 530. Along with the driving rod 210 continuing to approach the axis of the fixed ring 110, the first adjusting rod 220 and the second driving rod 210 continue to be far away, the first friction wheel 260 drives the workpiece to slide towards the first adjusting rod 220 until the second ultrasonic range finder 420 detects that the distance between the second adjusting rod 230 and the other end of the workpiece reaches a first preset value, the output signal of the second ultrasonic range finder 420 controls the second cylinder to start, the second cylinder drives the second telescopic rod to extend, the second locking block fixedly arranged at the other end of the second telescopic rod gradually approaches the second friction wheel 270, and the second friction wheel 270 stops rotating when the second locking block abuts against the second locking wheel due to the fact that the second locking wheel 270 is fixedly arranged on the second friction wheel 270. At this time, the output signals of the first ultrasonic range finder 410 and the second ultrasonic range finder 420 together control the start of the third cylinder 610, the third cylinder 610 drives the third telescopic rod to extend, the other end of the third telescopic rod is fixedly provided with a third locking block 620, and the third locking block 620 gradually approaches the driving rod 210 under the driving of the third telescopic rod. Since the sidewall of the driving rod 210 is provided with a plurality of slots 630, the plurality of slots 630 are uniformly distributed along the length direction of the driving rod 210. When the third locking block 620 abuts the driving rod 210, the third driving block blocks the driving rod 210 from sliding inward in the radial direction of the fixing ring 110.
If the distance between the second adjusting rod 230 and one end of the workpiece reaches the first preset value, but the distance between the first adjusting rod 220 and the other end of the workpiece does not reach the first preset value, the output signal of the second ultrasonic range finder 420 controls the second cylinder to start, the second cylinder drives the second telescopic rod to extend, and the second locking block fixedly arranged on the second telescopic rod gradually blocks the second friction wheel 270 from rotating. Along with the fact that the driving rod 210 continues to approach the axis of the fixed ring 110, the first adjusting rod 220 and the second driving rod 210 continue to be far away, the second friction wheel 270 drives the workpiece to slide towards the second adjusting rod 230 until the first ultrasonic range finder 410 detects that the distance between the first adjusting rod 220 and the other end of the workpiece reaches a first preset value, the output signal of the first ultrasonic range finder 410 controls the first air cylinder 510 to start, the first air cylinder 510 drives the first telescopic rod 540 to extend, and the first locking block 520 fixedly arranged on the first telescopic rod 540 gradually blocks the first friction wheel 260 from rotating. At this time, the output signals of the first ultrasonic range finder 410 and the second ultrasonic range finder 420 together control the activation of the third cylinder 610, the third cylinder 610 drives the third telescopic rod to extend, and the third locking block 620 fixedly arranged on the third telescopic rod gradually blocks the driving rod 210 from sliding.
If the distance between the first adjusting rod 220 and one end of the workpiece reaches the first preset value, and the distance between the second adjusting rod 230 and the other end of the workpiece reaches the first preset value, the output signals of the first ultrasonic range finder 410 and the second ultrasonic range finder 420 together control the start of the third cylinder 610, the third cylinder 610 drives the third telescopic rod to extend, and the third locking block 620 fixedly arranged on the third telescopic rod gradually blocks the driving rod 210 from sliding. Ensuring that the distance between the first adjusting lever 220 and the second adjusting lever 230 and the two ends of the workpiece is the same each time the workpiece is fixed increases the stability of clamping the workpiece.
