They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Given that in the current technology, when processing the piston rod of the shock absorber, it is necessary to rough grind the piston rod, but the existing piston rod rough grinding device requires stopping the machine to replace the next set of piston rods after rough grinding is completed, which is inconvenient and affects the efficiency of rough grinding.

[0026] like Figure 1-3As shown, this utility model embodiment provides a piston rod coarse grinding device, including a coarse grinding assembly 1: the coarse grinding assembly 1 includes: a coarse grinding mechanism 12 disposed on the top of a base 11, the coarse grinding mechanism 12 being a grinding roller; a mounting plate 13 disposed on the base 11; a first motor 14 disposed on the mounting plate 13; a turntable 15 disposed on the output end of the first motor 14; a connecting plate 151 symmetrically disposed on the turntable 15; a hydraulic rod 16 disposed on the connecting plate 151 and passing through the connecting plate 151; a concave frame 161 disposed on the output end of the hydraulic rod 16, and the concave frame 161 is concave to the side opposite to the hydraulic rod 16; a second motor 17 disposed on the concave frame 161; a screw 18 located on the side of the concave frame 161 away from the second motor 17 and threadedly connected to the concave frame 161; limiting rings 181 rotatably disposed on the output ends of the second motor 17 and the screw 18 respectively; and a piston rod 19 disposed inside the two sets of limiting rings 181.

[0027] When rough grinding of the piston rod 19 is required, first place the piston rod 19 inside the limiting ring 181 inside the concave frame 161 at the top. Then rotate the screw 18 threadedly connected to the concave frame 161 to push the limiting ring 181, which is rotatably connected to it, to compress and fix the piston rod 19. After fixing, start the first motor 14 through an external power source to drive the turntable 15 to rotate, rotating the concave frame 161 at the top to the bottom. Then, start the lower hydraulic rod 16 of the two hydraulic rods 16 through an external power source to press down the concave frame 161 connected to the hydraulic rod 16, and cause the piston rod to... Piston rod 19 contacts the coarse grinding mechanism 12. Then, the second motor 17 connected to the piston rod 19 is started by an external power source, which drives the limiting ring 181 to rotate, thereby causing the piston rod 19 to rotate slowly. At the same time, the coarse grinding mechanism 12 is started to drive the grinding roller to coarsely grind the outer wall of the rotating piston rod 19. Following the above steps, the next set of piston rods 19 that need to be coarsely ground can be installed inside the concave frame 161 at the top. The device has a simple structure and can disassemble or install the piston rods 19 that have been coarsely ground without stopping the machine, making it more convenient to use and improving work efficiency.

[0028] Furthermore, an auxiliary component 2 is provided on the base 11, the auxiliary component 2 including: a limiting rod 21 disposed on the top of the base 11 and threadedly connected to the base 11.

[0029] A limiting rod 21 is threaded on the top of the base 11 to limit the connecting plate 151 and keep it in a vertical position. This prevents the connecting plate 151 from rotating too much and affecting the rough grinding of the piston rod 19. When rotating the connecting plate 151, it can be removed by screwing on the limiting rod 21.

[0030] Furthermore, the auxiliary component 2 also includes a counterweight rod 22 symmetrically arranged on the limiting ring 181.

[0031] A counterweight rod 22 is symmetrically arranged on one side of the limiting ring 181. This ensures that the notches of the two sets of limiting rings 181 are always in the same direction when not in use, so that the piston rod 19 can be installed later.

[0032] Furthermore, the auxiliary component 2 also includes: an arc-shaped groove 23 formed on the mounting plate 13; and a ring 24 disposed on the turntable 15.

[0033] A ring 24 is provided on one side of the turntable 15, and an arc groove 23 is opened on one side of the mounting plate 13. This allows the ring 24 to slide inside the arc groove 23 when the turntable 15 rotates, increasing the structural strength of the turntable 15.

[0034] Furthermore, the auxiliary component 2 also includes a connecting block 25 disposed on the opposite sides of the two sets of connecting plates 151.

[0035] Connecting blocks 25 are provided on the opposite sides of the two sets of connecting plates 151, which can increase the structural strength of the two sets of connecting plates 151.

[0036] Furthermore, the connecting plate 151 is connected to the turntable 15 by bolts.

[0037] The connecting plate 151 and the turntable 15 are bolted together, so that if the parts on the connecting plate 151 are damaged later, they can be easily disassembled and replaced.

[0038] Furthermore, the auxiliary component 2 also includes slots 26 symmetrically arranged on the turntable 15.

[0039] Slots 26 are symmetrically opened on one side of the turntable 15. This allows the connecting plate 151 to be inserted into the slot 26 during subsequent installation, thus limiting the position of the connecting plate 151 for subsequent fixing with bolts.

[0040] Furthermore, the auxiliary component 2 also includes a rubber plate 27 disposed on the side of the limiting ring 181 that contacts the piston rod 19.

[0041] A rubber plate 27 is provided on one side of the inner side of the limiting ring 181, which can increase the fixing effect on the piston rod 19 by increasing the friction.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
