Two support plates 25 are provided and are respectively slidably connected in the sliding grooves 24. The driving motor 27 is fixedly connected to the side wall of the extending plate 22. The output rotating shaft of the driving motor 27 penetrates the side wall of the extending plate 22 and extends into the rotating groove 23. The gear 28 is fixedly connected to one end of the output rotating shaft of the driving motor 27 extending into the rotating groove 23. Two racks 26 are provided and are respectively fixedly connected to the side walls of the support plates 25. The two racks 26 are arranged in a staggered manner. The gear 28 is located between the two racks 26 and meshes with the racks 26 respectively.
[0059] In order to drive the auxiliary seat 14 to move up and down, a lifting member is further provided. The lifting member includes: a bottom plate 29, a lifting cylinder 13, a lifting plate 30, a guide block 31, and a sliding rod 32.
[0060] A through groove 12 is provided on the top wall of the pedestal 11, and the through groove 12 penetrates the top wall of the pedestal 11. The bottom plate 29 is fixedly connected to the bottom wall of the pedestal 11. The lifting cylinder 13 is fixedly connected to the bottom wall of the bottom plate 29. The lifting plate 30 is fixedly connected to the piston rod of the lifting cylinder 13. Two sliding rods 32 are provided and are symmetrically fixedly connected to the top wall of the lifting plate 30. The upper ends of the sliding rods 32 are fixedly connected to the bottom wall of the auxiliary seat 14. Two guide blocks 31 are provided and are symmetrically fixedly connected to the side walls of the through groove 12. The sliding rods 32 respectively penetrate the corresponding guide blocks 31, and the sliding rods 32 slide relative to the guide blocks 31. The auxiliary seat 14 is located directly above the through groove 12, and the side wall of the auxiliary seat 14 is in smooth contact with the groove wall of the through groove 12.
[0061] In order to clamp and fix the compressor piston, a clamping member is further provided. The clamping member includes: a guide rod 17, a clamping plate 19, and a clamping cylinder 18.
[0062] A plurality of guide rods 17 are provided and are symmetrically fixedly connected to the top wall of the main seat 15. The guide rods 17 respectively penetrate the clamping plate 19 and the clamping plate 19 slides relative to the guide rods 17. The clamping plate 19 is slidably connected to the guide rods 17. The clamping cylinder 18 is fixedly connected to the top wall of the first bracket 16. The piston rod of the clamping cylinder 18 is fixedly connected to the top wall of the clamping plate 19. Arc-shaped grooves are provided on the auxiliary seat 14, the main seat 15, and the clamping plate 19.
[0063] Working or installation process:
[0064] Place one end of the compressor piston on the arc-shaped groove of the main seat 15. Start the clamping cylinder 18. The piston rod of the clamping cylinder 18 extends and drives the clamping plate 19 to move downward. The clamping plate 19 moves downward along the guide rod 17. The arc-shaped groove of the clamping plate 19 contacts the arc surface of the compressor piston. At this time, the clamping cylinder 18 is always in a pressurized state, so that the clamping plate 19 and the main seat 15 clamp and fix the compressor piston.
[0065] Since the entire diameter of the compressor piston may be different, start the lifting cylinder 13. The piston rod of the lifting cylinder 13 extends and drives the lifting plate 30 to move upward. The lifting plate 30 drives the slide rod 32 to move upward. The slide rod 32 drives the auxiliary seat 14 to move upward and makes the arc-shaped groove of the auxiliary seat 14 contact a part of the outer wall of the compressor piston and support the compressor piston.
[0066] When milling the compressor piston, it may be necessary to rotate the compressor piston to improve the milling efficiency. Reverse-start the clamping cylinder 18 and make the clamping cylinder 18 release pressure. The clamping cylinder 18 drives the clamping plate 19 to move upward, and the clamping plate 19 releases the clamping of the compressor piston. (Since the compressor piston is cylindrical and die-cast from high-silicon aluminum alloy material) Move the compressor piston and make the compressor piston sleeve the insertion plate 22. The insertion plate 22 extends into the pipeline of the compressor piston. Start the drive motor 27. The output rotating shaft of the drive motor 27 drives the gear 28 to rotate. The gear 28 drives the two racks 26 to move in opposite directions by meshing with the two racks 26. The two racks 26 drive the support plates 25 on both sides to move in opposite directions respectively, and make the support plates 25 extend out of the chute 24. The arc-shaped ends of the support plates 25 are in pressing contact with the inner wall of the pipeline of the compressor piston. The drive motor 27 is a stepping motor and has a self-locking function. The drive motor 27 activates the self-locking function, and the drive motor 27 controls the gear 28 to stop rotating and start self-locking.
[0067] Start the flipping motor 21. The output rotating shaft of the flipping motor 21 drives the insertion plate 22 to rotate. The insertion plate 22 drives the support plate 25 to rotate. Since the arc-shaped ends of the support plates 25 are in pressing contact with the inner wall of the pipeline of the compressor piston, the support plates 25 drive the compressor piston to rotate synchronously.
[0068] When the flipping motor 21 drives the compressor piston to rotate, the clamping cylinder 18 is started again and pressurized. The clamping cylinder 18 drives the clamping plate 19 to move downward and performs a certain degree of clamping and limiting on the compressor piston, but the clamping of the clamping plate 19 and the main seat 15 does not prevent the compressor piston from rotating around the axis of the output rotating shaft of the flipping motor 21.
[0069] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) disclosed in the embodiments of the present disclosure that have similar functions.
