[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figures 1 to 9As shown, a surface processing device for shock absorber parts of the present invention includes a frame 10, a clamping assembly, a lower support 30, an upper support 31, a grinding block 1 32, a grinding block 2 33, a driving assembly and a clamping assembly. The clamping assembly is arranged on the top of the frame 10, and the clamping assembly can clamp the two ends of the shock absorber. The lower support 30 is arranged on the top of the frame 10, and the upper support 31 is arranged on the clamping assembly. After the clamping assembly clamps the two ends of the shock absorber, the upper support 31 is located directly above the lower support 30, and the upper support 31 and the lower support 30 can be aligned. The piston rod is wrapped with a smooth surface, and the grinding block 1 32 and the grinding block 2 33 are respectively arranged on the outer wall of one side of the lower support 30 and the upper support 31, the driving component is arranged on the top of the frame 10, and the driving component can drive the grinding block 1 32 to reciprocate along the length direction of the frame 10, and the clamping component is arranged on the side wall of the grinding block 2 33, and the clamping component has a first connection state and a second connection state. When in the first connection state, the grinding block 2 33 is connected to the upper support 31, and when in the second connection state, the grinding block 2 33 is connected to the grinding block 1 32.

[0039] When grinding the shock absorber, first place the shock absorber on the lower support 30, and the clamping assembly clamps and fixes the two ends of the shock absorber. Then the upper support 31 drives the second grinding block 33 to move downward, so that the upper support 31 and the lower support 30 wrap the outer peripheral surface of the piston rod, thereby protecting the smooth surface of the piston rod to avoid scratches caused by burrs or rust splashing during grinding. At the same time, the grinding block 1 32 and the grinding block 2 33 are attached to the outer peripheral surface of the piston cylinder, and the clamping assembly is changed from the first connection state to the second connection state. The driving assembly can then drive the grinding block 1 32 to move along the length direction of the frame 10, so that the grinding blocks 1 32 and 33 can reciprocate. Since grinding sandpaper is provided at the contact positions between the grinding blocks 1 32 and 33 and the outer peripheral surface of the piston cylinder, the outer peripheral surface of the piston cylinder can be polished by reciprocating the grinding blocks 1 32 and 33, thereby avoiding scratching the outer peripheral surface of the piston rod, thereby ensuring the service life of the shock absorber and improving the production efficiency.

[0040] like Figure 1 to Figure 2 As shown, the clamping assembly includes: a fixed plate 20, a telescopic rod 21, a clamping plate 22 and an L-shaped clamping plate 23. The two fixed plates 20 are arranged at intervals on the top of the frame 10, and the telescopic rods 21 are arranged on the opposite side walls of the two fixed plates 20. The clamping plate 22 and the L-shaped clamping plate 23 are arranged between the two fixed plates 20, and the clamping plate 22 is close to one of the fixed plates 20, and the end of the telescopic rod 21 on the fixed plate 20 is fixedly connected to the side wall of the clamping plate 22, and the L-shaped clamping plate 23 is close to the other fixed plate 20, and the end of the telescopic rod 21 on the fixed plate 20 is fixedly connected to the side wall of the L-shaped clamping plate 23, so that the telescopic rod 21 can push the L-shaped clamping plate 23 and the clamping plate 22 to move relative to each other, thereby clamping and fixing the two ends of the shock absorber.

[0041] A cylinder 24 is provided on the top of the L-shaped clamping plate 23, and a top extension piece 25 is provided on the output end of the cylinder 24. The bottom end of the top extension piece 25 is connected to the upper support 31, so that when the L-shaped clamping plate 23 moves, the upper support 31 can be driven to move, and semicircular grooves are provided on the opposite sides of the upper support 31 and the lower support 30. The semicircular grooves are used to wrap the outer peripheral surface of the piston rod. When the shock absorber is polished and fixed, the telescopic rod 21 pushes the L-shaped clamping plate 23 and the clamping plate 22 to move relative to each other, and the L The movement of the L-shaped clamping plate 23 drives the cylinder 24, the extension piece 25 and the upper support 31 to move synchronously. When the opposite side walls of the L-shaped clamping plate 23 and the clamping plate 22 are abutted against the two ends of the shock absorber, the upper support 31 is located directly above the lower support 30. Then the cylinder 24 controls the extension of the extension piece 25, and the extension of the extension piece 25 drives the upper support 31 to descend, so that the upper support 31 and the lower support 30 wrap the outer peripheral surface of the piston rod to avoid scratches during grinding and ensure the service life of the piston rod.

[0042] like Figures 5 to 9 As shown, the clamping assembly includes: a gear 60, an insert plate 1 61, an insert plate 2 50, a limit box 1 62 and a limit box 2 51. The gear 60 is arranged on the outer walls on both sides of the grinding block 2 33. A motor is arranged inside the grinding block 2 33, and the motor is connected to the gear 60 in a transmission manner. The insert plate 1 61 is slidably arranged on the outer walls on both sides of the grinding block 2 33. The limit box 1 62 is arranged on the outer walls on both sides of the upper support 31. The inner wall of the limit box 1 62 is provided with a rubber sheet. The insert plate 1 61 is also provided with a rubber sheet. The rubber sheet can increase the friction between the two, so that the insert plate 1 61 can be limited and matched with the limit box 1 62 to realize the connection or disconnection of the grinding block 2 33 and the upper support 31. The bottom wall of the insert plate 1 61 is provided with teeth, and the teeth are meshed with the gear 60.

[0043] The second plug plate 50 is fixedly set on the outer walls of both sides of the grinding block 33. A vertical groove 53 is opened on the second plug plate 50 along the length direction. A rack plate 54 is slidably set inside the vertical groove 53. The rack plate 54 can move along the length direction of the second plug plate 50. The rack plate 54 is meshed with the gear 60. A spring 55 is set on the bottom wall of the rack plate 54. The spring 55 can elastically support the rack plate 54. Two connecting plates 56 are set on the outer wall of one side of the rack plate 54. A connecting rod 57 is hinged between the two connecting plates 56. An insert block 59 is hinged at the end position of the connecting rod 57. A guide groove 58 is set in the vertical groove 53, and the insert block 59 is slidably set in the guide groove 58. The outer walls of both sides of the grinding block 32 are provided with a limit box 2 51, and a limit hole 52 is opened on the outer wall of one side of the limit box 2 51.

[0044] When the shock absorber is being polished, the cylinder 24 can drive the plug plate 2 50 to be inserted into the interior of the limit box 2 51. In order to connect the polishing block 2 33 with the polishing block 1 32, the motor will then drive the gear 60 to rotate. The gear 60 rotates clockwise to drive the rack plate 54 to move downward. At the same time, the gear 60 rotates clockwise to drive the plug plate 1 61 to move, so that the plug plate 1 61 in the limit box 1 62 is pulled outward, so that the polishing block 2 33 can be separated from the upper support 31, and the rack plate 54 moves downward to compress the spring 55. At the same time, the rack plate 54 drives the connecting rod 57 to tilt, so that the connecting rod 57 drives the plug block 59 to move along the length direction of the guide groove 58, thereby The plug block 59 can be inserted into the interior of the limiting hole 52, and the plug plate 2 50 can be inserted into the interior of the limiting box 2 51 and limited, so that the connection between the grinding block 2 33 and the grinding block 1 32 is achieved, and the clamping assembly is changed from the first connection state to the second connection state, so that the connection is more stable when the piston cylinder is polished, and the vibration of the machine table causes the grinding piece and the piston cylinder to not fit tightly enough to reduce the polishing effect, so that the outer surface of the piston cylinder can be efficiently polished and the polishing effect can be improved. After the polishing is completed, the motor drives the gear 60 to rotate counterclockwise, and the clamping assembly is changed from the second connection state to the first connection state, which is basically the same as the above principle and will not be elaborated here.

[0045] like Figures 2 to 4 As shown, the driving assembly includes: a screw 34, a driving box 35, a motor 41, a rotating rod 40, a bevel gear 1 42 and a bevel gear 2 43. Multiple screws 34 are arranged on one side outer wall of the lower support 30, and the screws 34 are threadedly connected to the grinding block 1 32, and one end of the screw 34 passes through the right side fixed plate 20, and the screw 34 is rotatably connected to the fixed plate 20. The driving box 35 is arranged on the outer side wall of the right side fixed plate 20, and the end of the screw 34 extends into the interior of the driving box 35. Cover plates 36 are arranged on both sides of the driving box 35. The rotating rod 40 is rotatably arranged on two opposite sides of the cover plate 36. The motor 41 is arranged on the side wall of one of the cover plates 36, and the output end of the motor 41 is connected to the rotating rod 40. The bevel gear 1 42 is arranged on the outer peripheral surface of the rotating rod 40, and the bevel gear 2 43 is arranged on the outer peripheral surface of the screw 34, and the bevel gear 1 42 is meshed with the bevel gear 2 43.

[0046] When the driving assembly drives the grinding block 1 32 and the grinding block 2 33 to move back and forth to grind the piston cylinder, the motor 41 drives the rotating rod 40 to rotate, and the rotation of the rotating rod 40 drives the bevel gear 1 42 to rotate. Since the bevel gear 1 42 is meshed with the bevel gear 2 43, the rotation of the bevel gear 1 42 drives the bevel gear 2 43 to rotate, and the rotation of the bevel gear 2 43 drives the lead screw 34 to rotate. The rotation of the lead screw 34 drives the grinding block 1 32 and the grinding block 2 33 to reciprocate along the length direction of the frame 10, thereby grinding the outer peripheral surface of the piston cylinder, improving the grinding efficiency, and avoiding scratches on the outer peripheral surface of the piston rod.

[0047] like Fig. 9 As shown, grinding pieces are also provided at the two side ends of the upper support 31 and the lower support 30. In this embodiment, the grinding piece is a self-rotating roller 90, and a grinding sheet is provided at the end of the self-rotating roller 90, so that after the upper support 31 and the lower support 30 wrap the piston rod, the self-rotating roller 90 will rotate to grind the end of the shock absorber, thereby improving the grinding efficiency.

[0048] like Figures 1 to 3 As shown, a vertical hole is provided on the top of the frame 10, and a push rod 12 is arranged in the vertical hole. A support plate 13 is arranged on the top of the push rod 12, and an arc-shaped groove is provided on the top surface of the support plate 13, and the arc-shaped groove can better fit with the outer circumferential surface of the piston cylinder, thereby improving the stability of the support plate 13 supporting the shock absorber. When the clamping assembly fixes and grinds the shock absorber, the push rod 12 drives the support plate 13 to move downward, so that the support plate 13 moves into the vertical hole, avoiding interference caused by the support plate 13 when the grinding block 1 32 and the grinding block 2 33 are grinding. A plurality of support legs 11 are provided on the bottom surface of the frame 10, and the support legs 11 are used to support the frame 10.

[0052] S3. The driving assembly can drive the grinding block 1 32 to move along the length direction of the frame 10, so that the grinding block 1 32 and the grinding block 2 33 can move back and forth, and the rotating roller 90 can grind the end of the shock absorber to improve the grinding efficiency.
