Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of a hydraulic cylinder barrel surface grinding device, comprising a base 1, a worktable 2 fixedly connected to the top of the base 1, a motor 3 fixedly connected to the top of the worktable 2 via a bracket, the motor 3 being a device that converts electrical energy into mechanical energy, a rotating rod 7 fixedly connected to the output end of the motor 3, a gear 4 fixedly connected to the outer wall of the rotating rod 7, a transmission gear 5 meshing with the outer wall of the gear 4, the power of the motor 3 being transmitted to the transmission gear 5 via the gear 4, a rotating ring 10 meshing with the outer wall of the transmission gear 5, the rotating ring 10 having teeth matching the transmission gear 5, allowing the rotating ring 10 to rotate with the transmission gear 5, a central column 11 fixedly connected to the upper surface of the base 1, a slider 12 slidably connected to the outer wall of the central column 11, the slider 12 having openings corresponding to the... The slot corresponding to the central column 11 facilitates the vertical movement of the slider 12. The outer wall of the slider 12 is hinged to the positioning rod 14 via the hinge rod 13. The bottom end of the slider 12 is slidably connected to the inclined block 15. A long rod is provided on the slider 12. When the inclined block 15 presses the long rod, the slider 12 moves vertically. The inner wall of the inclined block 15 is provided with a limiting mechanism. A saw-shaped groove 18 is provided on the upper surface of the base 1. Multiple sets of protrusions are provided at the opening of the saw-shaped groove 18. The protrusions initially block the locking block 16. A dust removal component is provided at the top of the worktable 2. The limiting mechanism includes the locking block 16. The bottom end of the locking block 16 is elastically connected to the inclined block 15 via a movable spring 17. The locking block 16 passes through and is slidably connected to the inner wall of the inclined block 15. The inclined block 15 is provided with a slot corresponding to the locking block 16, allowing the locking block 16 to move vertically.

[0034] Reference Figure 1 and Figure 2 The dust removal assembly includes an air blowing pipe 9, with an air bag 8 fixedly connected to the left end of the air blowing pipe 9. A cam 6 contacts the outer wall of the air bag 8. When the cam 6 contacts and squeezes the air bag 8, it will cause the air bag 8 to contract and expel the air inside. The air blowing pipe 9 is fixedly connected to the top of the workbench 2. Multiple sets of holes are opened on the air blowing pipe 9 to facilitate gas discharge. The cam 6 is fixedly connected to the outer wall of the rotating rod 7. The air bag 8 is fixedly connected to the top of the workbench 2. The air bag 8 is made of rubber polymer properties and high-strength fiber cloth vulcanized and can expand and contract. When it expands and contracts, it will absorb or expel air respectively.

[0035] Reference Figures 3-5The bottom end of the locking block 16 is fixedly connected to one end of the movable spring 17, and the other end of the movable spring 17 is fixedly connected to the inner wall of the top of the inclined block 15. When the locking block 16 moves downward, the movable spring 17 is compressed. When resetting, the elastic force of the movable spring 17 carries the locking block 16 back to its original position. The transmission gear 5 is rotatably connected to the top of the worktable 2. A cylinder is provided on the transmission gear 5, and a slot corresponding to the cylinder is opened on the worktable 2 to facilitate the rotation of the transmission gear 5. The rotating ring 10 is rotatably connected to the top of the worktable 2, and a slot corresponding to the rotating ring 10 is opened on the worktable 2 to facilitate the rotation of the rotating ring 10. The central column 11 is fixedly connected to the inner wall of the worktable 2. Rod 7 is rotatably connected to the top of workbench 2. The outer wall of slider 12 is hinged to one end of hinge rod 13, and the other end of hinge rod 13 is hinged to the outer wall of positioning rod 14. Since the length of hinge rod 13 is fixed, when slider 12 moves downward with one end of hinge rod 13, the other end of hinge rod 13 will bring the two sets of positioning rods 14 closer together. When slider 12 moves upward with one end of hinge rod 13, the other end of hinge rod 13 will separate the two sets of positioning rods 14. Inclined block 15 is slidably connected to the upper surface of base 1. The base 1 has a slot corresponding to inclined block 15, allowing inclined block 15 to move back and forth. Locking block 16 is inserted into the inner wall of saw groove 18.

[0036] Working principle: When positioning the hydraulic cylinder, the hand aligns the hydraulic cylinder and inserts it into the direction of the central column 11. The foot moves the locking block 16 downward, which compresses the movable spring 17. When the protrusion at the opening of the saw groove 18 no longer obstructs the locking block 16, the foot moves the locking block 16 and the inclined block 15 forward. The inclined block 15 compresses the slider 12 upward, which in turn moves the hinge rod 13 upward. The other end of the hinge rod 13 separates the two sets of positioning rods 14, which then fit against the inner surface of the hydraulic cylinder, thus completing the positioning of the hydraulic cylinder. At this point, the locking block 16 coincides with the opening of the saw groove 18. The foot releases the locking block 16, and the elastic force of the movable spring 17 causes the locking block 16 to insert into the groove of the saw groove 18. In the mouth, the protrusion blocks the locking block 16 and limit its movement. When the limit needs to be released, the foot moves the locking block 16 downward. When the protrusion blocks no longer block the locking block 16, the foot moves the locking block 16 backward. The locking block 16 will move backward with the inclined block 15. The inclined block 15 will squeeze the slider 12, causing the slider 12 to move downward with the hinge rod 13. The other end of the hinge rod 13 will bring the two sets of positioning rods 14 together. When the positioning rods 14 separate from the inner surface of the hydraulic cylinder, the limit on the hydraulic cylinder is released. At this time, the locking block 16 coincides with the slot on the saw groove 18. The foot releases the locking block 16, allowing the locking block 16 to be inserted into the slot of the saw groove 18. The protrusion blocks the locking block 16 and limit its movement. If the hydraulic cylinder needs to be positioned again, simply repeat the above operation steps.

[0037] When the hydraulic cylinder needs to be polished, the motor 3 is turned on by hand. The motor 3 will rotate the rotating rod 7, the cam 6 and the gear 4. The gear 4 will transmit power to the transmission gear 5 and the rotating ring 10, so that the rotating ring 10 will carry the polishing mechanism to polish the surface of the hydraulic cylinder. At the same time, when the cam 6 squeezes the air bag 8, the air bag 8 will be compressed and contract, expelling the air inside. The air will be blown towards the hydraulic cylinder through the air pipe 9, blowing away the dust and debris generated during the polishing of the hydraulic cylinder. When the cam 6 is no longer in contact with the air bag 8, the air bag 8 will draw in air and re-inflate. When the cam 6 comes into contact with the air bag 8 again, the air bag 8 will continue to repeat the above operation.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
