[0026] See also Figure 2 The grinding assembly 3 includes an assembly support 32, the bottom end of which is fixedly connected to the top of the rotating base 5, and the polished piston rod can be removed from it after polishing. When the rotating base 5 rotates, the assembly support 32 rotates accordingly. Three polishing rods 31 are arranged on the upper side of the inner end of the assembly support 32. The rotation of the assembly support 32 causes the polishing rods 31 to polish around the middle piston rod. A polishing port is opened in the middle of the assembly support 32 from top to bottom for the polished part of the piston rod to pass through.

[0027] See also Figure 3The component support 32 includes a component chassis 321, the bottom end of the component chassis 321 is fixedly connected to the top of the rotating base 5, and the component chassis 321 drives the entire component support 32 to rotate. Three guide blocks 322 are evenly fixedly connected to the outer side of the top of the component chassis 321. A guide groove is provided on the top of the guide block 322. The guide block 322 can limit the movement trajectory of the guide plate 311 therein. The middle part of the top of the component chassis 321 is rotatably connected to a rotating chassis 323. The rotating chassis 323 can rotate further on the basis of the rotation of the component chassis 321. Three support plates 327 are evenly fixedly connected to the top of the rotating chassis 323. The tops of the three support plates 327 are A fixed wheel 328 is connected to the same, and three rotating handles 329 are evenly fixedly connected to the top of the fixed wheel 328. The rotating handles 329 can more conveniently rotate the rotating chassis 323 when the piston rod enters and is pushed out for grinding. A contraction plate 326 is fixedly connected to the outer side of the support plate 327, and a contraction spring 325 is fixedly connected to the right end of the contraction plate 326. A contraction column 324 is fixedly connected to the end of the contraction spring 325 away from the contraction plate 326. The bottom end of the contraction column 324 is fixedly connected to the top of the component chassis 321. The contraction plate 326 and the contraction column 324 are mutually restricted by the contraction spring 325, so that the rotating chassis 323 can be kept at a certain rotation angle at all times.

[0028] See also Figure 3 The fixing wheel 328 and the rotating chassis 323 are evenly provided with three fixing holes, and the fixing holes of the fixing wheel 328 and the rotating chassis 323 are parallel to each other, and the fixing holes can limit the position of the fixed grinding rod 31.

[0029] See also Figure 4 The polishing rod 31 includes a guide plate 311, which slides in the guide groove and is restricted to a single-line sliding trajectory. A fixed column 312 is fixedly connected to the top of the guide plate 311, and a connecting column 313 is rotatably connected to the top of the fixing column 312. A control column 314 is fixedly connected to the top of the connecting column 313, and the control column 314 rotates in the fixing hole. The connecting column 313 will shrink inward due to the limitation of the fixing hole during the rotation of the rotating chassis 323, and the excess position will be consumed by the guide groove. A placement groove is provided at one end of the connecting column 313 away from the fixing column 312, and a friction wheel 315 is rotatably connected in the placement groove. When the friction wheel 315 shrinks inward with the connecting column 313, it will cling to the surface of the piston rod to polish it.

[0030] By turning the rotating handle 329 to rotate the rotating chassis 323 counterclockwise, the gap between the retracting plate 326 and the retracting column 324 becomes larger, and the connecting column 313 is offset outward under the restriction of the fixing hole. In order to keep the movement of the connecting column 313, the guide plate 311 will slide in the guide groove and follow the movement of the connecting column 313, so that a gap is opened between the three grinding rods 31 to pass the piston rod, and after the rotating handle 329 is released and the retracting spring 325 is pulled, each component produces a series of directional movements, causing the three friction wheels 315 to retract inward until they are close to the surface of the piston rod.

[0031] See also Figure 5 The fixing component 1 comprises a component handle 11, and the left and right sides of the component handle 11 are provided with fixed teeth to ensure that the clamping degree can be fixed. The bottom end of the component handle 11 is fixedly connected to a fixed connecting rod 13, and both ends of the fixed connecting rod 13 are rotatably connected to connecting connecting rods 14. The end of the connecting connecting rod 14 away from the fixed connecting rod 13 is rotatably connected to a contraction gear 15. Through a series of connecting rods, the rotation of the contraction gear 15 can be controlled. The outer surface of the contraction gear 15 is rotatably connected to a component body 18, and a concave shifting mechanism is provided on the bottom side of the component body 18. The bottom end of the contraction gear 15 is meshed with a contraction rack 16, and the front and rear ends of the contraction rack 16 slide in the movable groove. The rotation of the contraction gear 15 is controlled to control the sliding direction of the contraction rack 16 to achieve the effect of clamping and relaxing. The bottom ends of the two contraction racks 16 are close to each other and are fixedly connected with an arc-shaped fixed edge 17 at one end. The top of the component body 18 is rotatably connected to the two positioning teeth 12. The two positioning teeth 12 are located on the left and right sides of the component handle 11. The positioning teeth 12 can clamp the main fixed teeth to achieve the clamping of the fixed component 1.

[0032] By pressing down the assembly handle 11, the connecting rod can be driven to move, and the retraction gear 15 can be controlled to rotate inward, so as to control the retraction rack 16 meshing with the two retraction gears 15 to be relatively separated, thereby achieving a relaxation effect. On the contrary, by lifting the assembly handle 11, the retraction rack 16 can be relatively close to each other under the rotation of the two retraction gears 15, and the piston rod therein can be clamped by the arc-shaped fixed edge 17.

[0033] See also Figure 6 The support component 2 includes a rotating wheel 21, a driving motor is provided at the bottom end of the rotating wheel 21, the top end of the rotating wheel 21 is fixedly connected to the bottom end of the rotating base 5, a synchronous belt 22 is sleeved on the outer surface of the rotating wheel 21, and the end of the synchronous belt 22 away from the rotating wheel 21 is rotatably connected to a rotating movable column 23, and the end of the rotating movable column 23 away from the synchronous belt 22 is threadedly connected to a moving beam 24, and the end of the moving beam 24 away from the rotating movable column 23 is slidably connected to a limiting column 25, and the end of the limiting column 25 away from the moving beam 24 is fixedly connected to a limiting block 26, the bottom end of the limiting block 26 is fixedly connected to the top of the machine base 4, and the middle part of the moving beam 24 is fixedly connected to the outer surface of the fixed component 1.

[0034] The rotating wheel 21 is driven by a driving motor to rotate, and the rotating wheel 21 drives the rotating base 5 and the grinding component 3 to rotate. At the same time, the rotating movable column 23 can be rotated together through the synchronous belt 22. When the rotating movable column 23 rotates, the movable beam 24 cannot rotate due to the restriction of the restriction column 25, and can only move up and down through the thread, driving the fixed component 1 in the middle of the movable beam 24 to move, and stop after reaching a predetermined position.

[0035] Working principle:

[0036] First, press the assembly handle 11 to separate the retractable racks 16 from each other, put the piston rod to be polished between the arc-shaped fixed edges 17, and then lift the assembly handle 11 to close the retractable racks 16 to fix the piston rod, and then turn the positioning tooth 12 to fix the assembly handle 11, so that the retractable rack 16 remains fixed and will not be displaced, and then turn the rotating handle 329 to open the gap between the polishing rods 31, and put in the piston rod at the other end so that the retractable spring 325 can be tightly polished to the piston rod, and then start the machine. The piston rod therein will be polished under the rotation of the rotating base 5 and the polishing assembly 3, and at the same time, the moving beam 24 will move downward due to the rotation of the rotating moving column 23 to transport the piston rod downward for polishing. After the polishing is completed, the piston rod can be taken out from the lower picking space in reverse order.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
