[0027] The first linear motor 41 , the second linear motor 43 and the stepper motor 45 are all connected to a controller (not shown).
[0028] Six claws 2 are evenly arranged on the workbench 11 along the circumferential direction outside the opening of the through hole 10, and placement grooves 111 are provided at the positions of the claws 2 on the workbench 11, and a first cylinder 12 connected to the controller is provided in each of the placement grooves 111, and the output end of the first cylinder 12 at the corresponding position is fixedly connected to the claw 2; a pneumatic pressure block 21 is provided on each of the claws 2; and a step surface structure with a wider bottom and a narrower top is provided on the inner side wall of each of the claws 2.
[0029] The operating principle of the utility model is as follows:
[0030] like Figures 1 to 5 As shown, the controller in this embodiment is preferably a PLC controller. When in use, the workpiece is first placed on the support plate 3, and the limiting boss 31 extends into the middle inner hole of the workpiece to achieve fixed limiting of the workpiece. Then, the limiting block 62 is pulled out from the positioning hole 65, and the boss 64 is rotated. Since the upper end surface of the boss 64 is fixedly connected to the first linear motor 41, that is, the first linear motor 41 also rotates synchronously and drives the support plate 3 to rotate horizontally to the top of the workbench 11. After the boss 64 is rotated into place, the limiting block 62 connected to the tension spring 66 is released. Under the action of elastic force, the limiting block 62 extends into the positioning hole 65 at the corresponding position to achieve rotation limiting of the boss 64; the boss 64 set by the bearing sleeve on the support rod 63 has a small rotation resistance, which is convenient for the boss 64 to rotate into place quickly.
[0031] 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 the connecting plate 44, the output end of the stepper motor 45 is connected to the support plate 3 by a connecting rod 46, that is, the first linear motor 41 also synchronously drives the support plate 3 to move downward.
[0032] When the workpiece moves down to the step structure position on the inner wall of the clamping claw 2, the controller starts the six cylinders 12 provided in this embodiment at the same time. 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 position 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.
[0033] Then, the six cylinders 12 continue to push the claws 2 at the corresponding positions 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 limit of the workpiece in the horizontal and vertical directions; after the support plate 3 moves down to a certain position, the first linear motor 41 is turned off, and the controller turns on the stepper motor 45 at the same time to drive 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 make way groove 141. At this time, the tooth turning (referred to as tooth turning) processing can be started.
[0034] After the processing is completed, the controller starts the second linear motor 43 to drive the connecting plate 44 to move, and makes the support plate 3 move into the through hole 10 of the workbench 11 through the make way slot 141, and then the second linear motor 43 is closed, 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 closed, and the first linear motor 41 is started again to drive the support plate 3 to move upward. During the upward movement, the controller simultaneously starts the six cylinders 12 and the pneumatic pressure block 21 to drive the six claws 2 to move slowly outward. The pneumatic pressure block 21 rotates horizontally away from the upper position of the workpiece until the edge of the upper end face of the support plate 3 abuts against the lower end face of the workpiece. At this time, the limiting boss 31 extends into the inner hole of the workpiece, and the 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.
[0035] Finally, pull out the limit block 62 from the positioning hole 65, rotate the boss 64, and the support plate 3 will rotate synchronously and leave the position of the workbench 11. After the boss 64 is rotated into place, release the limit block 62 connected to the tension spring 66. Under the action of elastic force, the limit block 62 extends into the positioning hole 65 at the corresponding position to realize the rotation limit of the boss 64. Then start the first linear motor 41 to move the support plate 3 down to a height position suitable for manually moving the workpiece (the height position is preset on the controller), remove the workpiece, and then put the next workpiece to be processed on it. According to the corresponding steps mentioned above, the purpose of fast material taking and placing can be achieved.
[0036] The outer wall of the limiting boss 31 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.
[0037] It should be noted that if Figure 3 and Figure 4 As shown, for ease of use, two positioning holes 65 are symmetrically provided on the boss 64, that is, each time the boss 64 rotates 180°, it is the position for placing or taking out materials, and the limit block 62 can extend into the positioning hole 65 at the corresponding position to realize the rotation limit of the boss 64 to ensure the accuracy of the movement of the workpiece.
[0038] The controller in this embodiment is only set to application control and does not involve program improvement of the controller. Therefore, the connection between the controller and various device components will not be repeated here.
