[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Specific examples are given below.

[0027] See also Figure 1 - Figure 6 The utility model provides a bicycle piston grinding device, comprising a workbench 1 and a bracket 2. A slide groove 3 is provided on the top of the workbench 1. Two slide rods 7 are fixedly connected inside the slide groove 3, and a slider 4 is slidably connected to the middle of the two slide rods 7. A driving motor 5 is fixedly connected to one end of the workbench 1, and a threaded rod 6 is fixedly connected to one end of the output shaft of the driving motor 5. Both ends of the threaded rod 6 are rotatably connected to the inner wall of the workbench 1, and the middle outer wall of the threaded rod 6 is threadedly connected to the inner wall of the slider 4. Two rotating grooves 41 are provided on the top of the slider 4, and a rotating disk 8 is rotatably connected to the top of each rotating groove 41, and a plurality of positioning blocks 9 are fixedly connected to the top of each rotating disk 8, and the plurality of positioning blocks 9 are arranged in a ring array. An electric push rod 10 is fixedly connected to the middle of each positioning block 9, and a positioning plate 11 is fixedly connected to one end of each electric push rod 10, and a clamping block 12 is fitted and connected to one side of each positioning plate 11. The bracket 2 is fixedly mounted on the top of the workbench 1. An open slot 21 is provided on the top of the bracket 2. A connection box 23 is slidably connected inside the open slot 21. A second push rod 15 is fixedly connected inside the open slot 21. One end of the second push rod 15 is fixedly connected to a push plate 16. A servo motor 17 is fixedly connected to one side of the push plate 16. A grinding head 18 is fixedly connected to one end of the output shaft of the servo motor 17.

[0028] During operation, the piston to be processed is placed on the top of the turntable 8, and then multiple electric push rods 10 are used to push the positioning plate 11 to drive the clamping block 12 to move, so that the multiple clamping blocks 12 are attached to the outside of the piston to clamp and fix the piston. The tooth groove on one side of the clamping block 12 can reduce the rotation of the piston during grinding, thereby improving the grinding effect of the piston. The positioning block 9 is then used to ensure the stability of the turntable 8, prevent the structure from being misaligned when clamping the piston, and improve the use efficiency of the structure. Then the drive motor 5 is started, and the output shaft of the drive motor 5 is used to drive the threaded rod 6 to rotate, so that the slider 4 can slide inside the slide groove 3, and then a turntable 8 is moved to the bottom of the grinding head 18. Two slide rods 7 can be used to prevent the slider 4 from being misaligned when moving, thereby improving the stability of the structure. Then the servo motor 17 is started, and the output shaft of the servo motor 17 is used to drive the grinding head 18 to rotate, and the second push rod 15 is used to push the push plate 16 to slide inside the connection box 23, driving the servo motor 17 to fall so that the grinding head 18 contacts the piston, and the piston can be polished. When the polished piston needs to be replaced, the polishing head 18 is lifted off the piston by the contraction of the second push rod 15, and then the drive motor 5 is started to drive the slider 4 to slide inside the slide groove 3 again, and the other turntable 8 is moved to the bottom of the polishing head 18, so that the worker can replace the piston. Then repeating the above steps can not only prevent injuries to workers when replacing the piston, but also will not affect the normal use of the equipment, and can improve the grinding efficiency of the piston, and improve the practicality and service life of the equipment.

[0029] Further, such as Figure 3 As shown, a hydraulic push rod 22 is fixedly connected to one side of the connection box 23, and the middle part of the hydraulic push rod 22 is fixedly connected to the inner wall of the bracket 2, and the connection box 23 slides inside the opening slot 21 through the hydraulic push rod 22. Rectangular blocks 24 are fixedly connected to both ends of the connection box 23, and a positioning rod 25 is slidably connected inside each rectangular block 24, and both ends of each positioning rod 25 are fixedly connected to the inner walls of both sides of the opening slot 21, and each rectangular block 24 is slidably connected to the inner walls of both sides of the opening slot 21 through the positioning rod 25.

[0030] During operation, the hydraulic push rod 22 can be extended and retracted to drive the connection box 23 to slide inside the opening groove 21. The connection between the rectangular block 24 and the positioning rod 25 can prevent the connection box 23 from being misplaced during movement, thereby improving the stability of the structure. It can also prevent the grinding head 18 from shaking during grinding the piston, thereby improving the grinding effect of the piston. As the hydraulic push rod 22 drives the connection box 23 to move, the position of the grinding head 18 grinding the piston can be adjusted to a certain extent, thereby improving the practicality of the equipment.

[0031] Further, such as Figure 4As shown, a small motor 45 is fixedly connected inside each rotating groove 41, and a gear 44 is fixedly connected to one end of the output shaft of each small motor 45, and a gear ring 43 is meshed and connected to one side of each gear 44. A rotating rod 42 is fixedly connected inside each gear ring 43, and one end of each rotating rod 42 is fixedly connected to the rotating disk 8, and the other end of each rotating disk 8 is rotatably connected to the inner wall of one side of the rotating groove 41, and each rotating rod 42 rotates inside the rotating groove 41 through the gear ring 43.

[0032] During operation, by starting the small motor 45 inside the rotating groove 41, the output shaft of the small motor 45 is used to drive the gear 44 to rotate, which can drive the gear ring 43 meshing with the gear 44 to rotate, and can drive the rotating rod 42 to rotate inside the rotating groove 41. Then, by using the fixed connection between one end of the rotating rod 42 and the rotating disk 8, the rotating disk 8 can be rotated on the top of the slider 4, and the grinding position of the piston can be rotated and adjusted to reduce the intervention of workers. Then, by using the engagement between one side of the rotating disk 8 and the top of the rotating groove 41, the rotating disk 8 can be prevented from being misaligned during the rotation process, thereby improving the use efficiency of the device.

[0033] Further, such as Figure 6 As shown, one side of each clamping block 12 is fixedly connected to a trapezoidal block 14, one side of each trapezoidal block 14 is provided with a trapezoidal groove 13, each trapezoidal groove 13 is opened on the inner wall of one side of the positioning plate 11, the interior of each trapezoidal groove 13 is fitted and connected to the outer wall of the trapezoidal block 14, and each clamping block 12 is fitted to one side of the positioning plate 11 through the trapezoidal block 14.

[0034] During operation, when the clamp block 12 is damaged after long-term use, the clamp block 12 can be easily removed by pulling the top of the clamp block 12 so that the two trapezoidal blocks 14 are pushed away from the inside of the trapezoidal groove 13, and then the two trapezoidal blocks 14 on one side of the new clamp block 12 are inserted into the inside of the trapezoidal groove 13. Then, the clamp block 12 is pressed so that the trapezoidal blocks 14 are completely fitted with the inner wall of the trapezoidal groove 13, so that the clamp block 12 is fixed on one side of the positioning plate 11, and the replacement of the clamp block 12 is completed, which is convenient for the staff to operate and improves the clamping effect on the piston.

[0035] Working principle: The piston to be processed is placed on the top of the turntable 8, and then a plurality of electric push rods 10 are used to push the positioning plate 11 to drive the clamping block 12 to move and clamp the piston. Then the drive motor 5 is started, and the output shaft of the drive motor 5 is used to drive the threaded rod 6 to rotate, so that the slider 4 can slide inside the slide groove 3, and then a turntable 8 is moved to the bottom of the grinding head 18. The hydraulic push rod 22 is used to extend and retract to drive the connection box 23 to slide inside the opening groove 21. The connection between the rectangular block 24 and the positioning rod 25 can prevent the connection box 23 from being misaligned during movement, and the grinding head 18 can be moved directly above the piston. Then the servo motor 17 is started, and the output shaft of the servo motor 17 is used to drive the grinding head 18 to rotate, and the second push rod 15 is used to push the push plate 16 to slide inside the connection box 23, driving the servo motor 17 to fall so that the grinding head 18 contacts the piston. Then start the small motor 45 inside the rotating groove 41, and use the output shaft of the small motor 45 to drive the gear 44 to rotate, which can drive the gear ring 43 meshing with the gear 44 to rotate, and can drive the rotating rod 42 to rotate inside the rotating groove 41. Then, by using the fixed connection between one end of the rotating rod 42 and the rotating disk 8, the rotating disk 8 can rotate on the top of the slider 4, and the grinding position of the piston can be adjusted by rotation to complete the grinding of the piston. When the polished piston needs to be replaced, the grinding head 18 is lifted off the piston by the contraction of the second push rod 15. Then start the driving motor 5, and drive the slider 4 to slide inside the slide groove 3 again, and move another rotating disk 8 to the bottom of the grinding head 18. Repeat the above steps to grind another piston. Then, by using the contraction of multiple electric push rods 10 on the top of the first rotating disk 8, the piston can be removed, and then the piston to be polished is placed on the top of the rotating disk 8, and the clamping block 12 is used to clamp and fix it again to complete the replacement of the piston.
