[0026] A sleeve 32 is provided on the support plate 3 at a position corresponding to the support rod 31 . When in use, the second cylinder 13 drives the support rod 31 to extend out and extend into the sleeve 32 . An annular limiting boss 33 is provided on the support plate 3 .
[0027] A support plate 47 is provided at the lower end of the connecting plate 44 . One side of the support plate 47 is connected to the connecting plate 44 , and the other side of the support plate 47 is connected to the fixing rod 15 .
[0028] The first linear motor 41 , the second linear motor 43 , the stepper motor 45 and the second cylinder 13 are all connected to a controller.
[0029] The operating principle of the utility model is as follows:
[0030] like Figures 1 to 4 As shown, when in use, the workpiece is first placed on the support plate 3, and the limiting boss 33 extends into the middle inner hole of the workpiece to achieve fixed limiting of the workpiece. At this time, the support rod 31 extends into the sleeve 32 to assist in supporting the support plate 3; then, the controller turns on the first linear motor 41 to synchronously drive the base plate 42 and the connecting plate 44 to move downward. Since a connecting plate 44 connected to the second linear motor 43 is fixedly provided on the base plate 42, and a stepper motor 45 is provided on one side of the connecting plate 44, and a second cylinder 13 is provided on the other side, and the output end of the stepper motor 45 is connected to the support plate 3 by a connecting rod 46, and the output end of the second cylinder 13 is provided with a horizontally extended support rod 31, that is, the first linear motor 41 also synchronously drives the support plate 3 and the support rod 31 to move downward.
[0031] When the workpiece moves down to the step structure position on the inner wall of the clamping claw 2, the controller simultaneously starts the six first cylinders 12 provided in this embodiment, and the six clamping claws 2 are retracted but do not affect the downward movement of the workpiece. Finally, the step surface of the step structure is abutted against the outer edge of the lower end surface of the workpiece. At this time, the support plate 3 continues to move downward with the first linear motor 41, and the workpiece remains on the six clamping claws 2.
[0032] Then, on the one hand, the six first cylinders 12 continue to push the corresponding claws 2 to move and clamp the outer wall of the workpiece at the same time. At the same time, the controller simultaneously turns on the six pneumatic pressure blocks 21, and the six pneumatic pressure blocks 21 are pressed on the upper end surface of the workpiece to achieve fixed positioning of the workpiece in the horizontal and vertical directions. On the other hand, during the downward movement of the support plate 3, the controller starts the second cylinder 13 to move the support rod 31 out of the workbench 11 along the second clearance groove 142. After the support plate 3 moves down to a certain position, the first cylinder 13 is closed. The linear motor 41, and the controller turns on the stepper motor 45 at the same time, driving the connecting rod 46 and the support plate 3 to rotate synchronously. It should be noted that the flipping of the support plate 3 will not interfere with the workpiece in the upper position. After the support plate 3 is flipped 90°, the stepper motor 45 is turned off, and the controller simultaneously starts the second linear motor 43 to drive the connecting plate 44 to move outward, and the flipped support plate 3 to the vertical state is moved out of the workbench 11 through the first make way groove 141. At this time, the tooth turning process (referred to as tooth turning) can be started.
[0033] After the processing is completed, the controller starts the second linear motor 43 to drive the connecting plate 44 to move, and moves the support plate 3 into the through hole 10 of the workbench 11 through the first clearance groove 141. Then, the second linear motor 43 is turned off, and the stepper motor 45 is started to drive the connecting rod 46 and the support plate 3 to rotate synchronously. When the support plate 3 rotates to a horizontal position, the stepper motor 45 is turned off, and the second cylinder 13 is started at the same time to drive the support rod 31 to extend into the sleeve 32 along the second clearance groove 142. Then, the second cylinder 13 is turned off, and the first linear motor 41 is started. Drive the support plate 3 and the support rod 31 to move upward synchronously. During the upward movement, the controller simultaneously starts the six first cylinders 12 and the pneumatic pressure block 21, driving the six claws 2 to move slowly outward, and the pneumatic pressure block 21 rotates horizontally away from the upper position of the workpiece until the edge of the upper end surface of the support plate 3 abuts against the lower end surface of the workpiece. At this time, the limiting boss 33 extends into the inner hole of the workpiece, and the first cylinder 12 is closed. The workpiece continues to move upward with the abutting support plate 3 until the workpiece is completely moved above the pneumatic pressure block 21, and the first linear motor 41 is closed to remove the workpiece.
[0034] The outer wall of the limiting boss 33 should fit with the hole wall of the inner hole of the workpiece to facilitate movement and limit, thereby preventing the workpiece from moving and causing clamping interference, and ensuring the safety of processing and the stability of processing quality.
[0035] The controller in this embodiment is preferably a PLC controller, which is only set to application control and does not involve program improvement of the controller. Therefore, the connection between the controller and various equipment components will not be repeated here.
