[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-5 A piston polishing machine that is easy to fix includes a base 1, a fixed seat 2 fixedly connected to the top of the base 1, multiple sets of slide rods 3 equidistantly slidably connected inside the fixed seat 2, a clamping plate 4 fixedly connected to one end of each set of slide rods 3 extending into the interior of the base 1, a support frame 5 fixedly connected to the top of the base 1 near the fixed seat 2, slide plates 6 slidably connected to both sides of the bottom of the support frame 5, arc plates 7 fixedly connected to the inner sides of the two slide plates 6, and polishing blocks 8 provided on the inner sides of the two arc plates 7, and a transmission assembly is provided inside the fixed seat 2.

[0022] Specifically, the transmission assembly includes a first motor 9 and a linkage unit. The first motor 9 is fixedly connected to the top side of the base 1 via a mounting block. The output end of the first motor 9 extends into the interior of the base 1 and is fixedly connected to a first helical gear 10. A second helical gear 11 is rotatably connected inside the fixed seat 2. The first helical gear 10 and the second helical gear 11 are meshed together. A rotating sleeve 12 is rotatably connected at equal intervals inside the fixed seat 2. A third helical gear 13 is fixedly connected to the outside of the rotating sleeve 12. A transmission screw 14 is threadedly connected inside the rotating sleeve 12. Multiple transmission screws 14 are connected to the fixed seat. The inner wall of plate 2 is slidably connected, and multiple transmission screws 14 are rotatably connected to the corresponding clamping plates 4. The arc plate 7 can be moved through the linkage unit. The linkage unit includes a first pulley 15, which is fixedly connected to the outside of the output end of the first motor 9. A bidirectional screw 16 is rotatably connected to the upper part of the inside of the support frame 5. One end of the bidirectional screw 16 extends to the outside of the support frame 5 and is fixedly connected to a second pulley 17. The first pulley 15 and the second pulley 17 are connected by a transmission belt 18. Two sliding plates 6 are threadedly connected to the outer sides of the bidirectional screw 16.

[0023] With the above technical solution, when the piston needs to be polished, firstly, the bottom of the piston is placed inside the fixed seat 2, and the top of the piston is placed between the two polishing blocks 8. The piston can be lifted by the second spring at the bottom of the support plate 26, so that the top of the piston is in contact with the bottom of the polishing block 8. Then, the first motor 9 is started by the external controller. The output end of the first motor 9 drives the first helical gear 10 and the first pulley 15 to rotate, so that the first helical gear 10 drives the second helical gear 11 to rotate through the meshing relationship. The second helical gear 11 then drives multiple third helical gears 13 and the rotating sleeve 12 to rotate through the meshing relationship. So that the rotating sleeve 12 drives the transmission screw 14 and the corresponding clamping plate 4 to move towards the inside of the fixed seat 2 under the limit of the slide rod 3, until the multiple clamping plates 4 clamp the piston. During the rotation of the first pulley 15, the second pulley 17 and the double screw 16 can be driven to rotate through the transmission belt 18, so that the double screw 16 is driven by the threaded connection. The sliding plates 6 on both sides move inward, thereby pushing the corresponding grinding blocks 8 towards the piston until the inner walls of the grinding blocks 8 on both sides are in contact with the outer wall of the piston. At this time, the second motor 19 is started by the external controller, so that the output end of the second motor 19 drives the limiting plate 20 to rotate. The limiting plate 20 drives the grinding blocks 8 on both sides of the bottom to rotate under the limitation of the sliding protrusion 24 and the sliding groove 25, thereby achieving the purpose of grinding the outer wall and top surface of the piston at the same time. This avoids the problem of difficulty in grinding the top surface and outer wall of the piston at the same time in traditional technology, effectively improving the grinding efficiency. After the piston is placed inside the fixed seat 2, the top of the piston is lifted upward by the support plate 26 until the top of the piston is in contact with the bottom of the grinding block 8. Then, during the process of clamping the piston by the clamping plate 4, the corresponding grinding blocks 8 can be pushed to be in contact with the outer wall of the piston by the two arc plates 7, thereby achieving the purpose of grinding the outer wall and top surface of the piston at the same time, effectively improving the grinding efficiency.

[0024] Specifically, a second motor 19 is fixedly connected to the upper interior of the support frame 5 via a mounting bracket. A limit plate 20 is fixedly connected to the output end of the second motor 19. Limit rods 21 are fixedly connected to both sides of the bottom of the limit plate 20. Two arc-shaped plates 7 are slidably connected to the outside of the corresponding limit rods 21 via two sliders 22. A first spring 23 is provided outside the limit rods 21 and between the sliders 22 and the inner wall of the limit plate 20. A sliding protrusion 24 is fixedly connected to one side of the arc-shaped plate 7. A groove 25 is provided on the inner side of the arc-shaped plate 7. The sliding protrusion 24 is slidably connected to the inside of the groove 25. A support plate 26 is provided at the lower interior of the fixed seat 2. A second spring is provided between the support plate 26 and the fixed seat 2. Both the first motor 9 and the second motor 19 are electrically connected to an external controller.

[0025] With the above technical solution, after the piston is polished, the clamping plate 4 and the arc plate 7 can be moved away from the piston by the reverse process operation, and the two polishing blocks 8 move away from the piston under the rebound force of the first spring 23. Then, the piston can be manually pressed down to drive the support plate 26 to descend, and the piston can be taken out. The first motor 9 and the second motor 19 can be quickly controlled by the staff through the external controller.

[0026] When polishing the piston during use, first place the bottom of the piston inside the fixed base 2, and place the top of the piston between the two polishing blocks 8. The second spring at the bottom of the support plate 26 can lift the piston, so that the top of the piston fits against the bottom of the polishing block 8. Then, the first motor 9 is started by the external controller. The output end of the first motor 9 drives the first helical gear 10 and the first pulley 15 to rotate, so that the first helical gear 10 drives the second helical gear 11 to rotate through meshing. The second helical gear 11 then drives multiple third helical gears 13 to rotate through meshing. As sleeve 12 rotates, it drives the transmission screw 14 and the corresponding clamping plate 4 to move inward toward the fixed seat 2 under the limit of slide rod 3, until multiple clamping plates 4 clamp the piston. During the rotation of the first pulley 15, the transmission belt 18 drives the second pulley 17 and the double-acting screw 16 to rotate, causing the double-acting screw 16 to drive the sliding plates 6 on both sides to move inward through the threaded connection. This, in turn, pushes the corresponding grinding blocks 8 toward the piston until the inner walls of the grinding blocks 8 on both sides are in contact with the outer wall of the piston. At this point, the transmission... The second motor 19 is started by an external controller, causing its output to drive the limiting plate 20 to rotate. This, in turn, causes the grinding blocks 8 on both sides of the bottom to rotate under the constraint of the sliding protrusion 24 and the sliding groove 25. This achieves simultaneous grinding of the piston's outer wall and top surface, avoiding the problem of simultaneously grinding the piston's top surface and outer wall in traditional technologies, effectively improving grinding efficiency. After the piston is placed inside the fixed seat 2, the support plate 26 can lift the top of the piston upwards until the top of the piston is in contact with the bottom of the grinding block 8. During the process of clamping the piston by the clamping plate 4, the two arc plates 7 can push the corresponding grinding blocks 8 to stick to the outer wall of the piston, thereby achieving the purpose of grinding the outer wall and top surface of the piston at the same time, effectively improving the grinding efficiency. After the piston is ground, the clamping plate 4 and the arc plates 7 can be moved away from the piston by the reverse process, and the two grinding blocks 8 move away from the piston under the rebound force of the first spring 23. Then, the piston can be manually pressed down to drive the support plate 26 to descend, and the piston can be taken out. The first motor 9 and the second motor 19 can be quickly controlled by the operator through the external controller.
