A polishing device for shock absorber piston production

Abstract

This utility model discloses a grinding device for shock absorber piston production, belonging to the field of piston production and processing. It includes a worktable with a slot on its top. A rotary drive mechanism is horizontally arranged on the top of the worktable, and a grinding mechanism is located on the top of the worktable and behind the rotary drive mechanism. A moving drive mechanism is located inside the slot, and the rotary drive mechanism is positioned above the moving drive mechanism. The rotary drive mechanism includes two rotating cylinders. A piston rod is placed between the two rotating cylinders. The piston rod rotates due to friction caused by the rotation of the cylinders, replacing the rotation function of the existing fixed mechanism. Simultaneously, a stop block pushes the piston rod towards the fixed grinding mechanism. This eliminates the need for left-right translation of the grinding mechanism, enabling simultaneous grinding of the piston rod's rotation and movement. This allows for continuous grinding of the piston rod without stopping the machine, effectively improving overall grinding efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of piston manufacturing and processing technology, specifically relating to a grinding device for shock absorber piston manufacturing. Background Technology

[0002] As the core moving component for damping adjustment and vibration buffering, the shock absorber piston is initially processed using long steel pipes as raw materials. First, professional CNC grinding equipment removes the surface oxide layer, burrs, and unevenness (ensuring a surface roughness Ra≤0.8μm). Then, according to the size requirements of different shock absorber models, it is cut to length in sections using laser or high-precision sawing equipment (controlling the length error within ±0.05mm). Finally, CNC milling equipment processes sealing grooves, guide grooves, and other grooves to accommodate subsequent sealing components and auxiliary structure assembly. In actual use, the outer surface of the piston is fitted with an elastic sleeve made of oil-resistant, wear-resistant, and aging-resistant nitrile rubber or polyurethane. This elastic sleeve reduces direct friction loss between the piston and the cavity wall during high-frequency reciprocating motion.

[0003] The piston rod is a dedicated basic component for the initial processing of shock absorber pistons. It is made of long solid steel pipe and serves as the core raw material for subsequent initial processing steps such as grinding, cutting, and grooving. Existing grinding devices used in shock absorber piston production fix both sides of the piston rod with a fixing device. The fixing mechanism has a rotation function, and the grinding mechanism moves left and right during grinding. This method makes it impossible to quickly connect the processing of the next piston rod after grinding a single piston rod, resulting in low overall grinding efficiency. Therefore, a grinding device for shock absorber piston production is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for the production of shock absorber pistons, so as to solve the problem that the existing processing cannot quickly connect to the next piston rod and the overall grinding efficiency is low.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for producing shock absorber pistons, comprising a workbench, wherein a groove is formed on the top of the workbench;

[0006] A rotary drive mechanism is horizontally arranged on the top of the worktable, and a grinding mechanism is arranged on the top of the worktable and behind the rotary drive mechanism. A moving drive mechanism is arranged inside the first slot, and the rotary drive mechanism is located above the moving drive mechanism.

[0007] The rotary drive mechanism includes two self-rotating first rotating cylinders, which are respectively mounted on two first rotating shafts. The distance between the two first rotating cylinders is less than the diameter of the piston rod. Both ends of the two first rotating shafts are rotatably mounted on the mounting base.

[0008] The moving drive mechanism includes a stop block that can move within a movable slot number one. The stop block is mounted on a transmission component number two, which can drive the stop block to circulate through slot number one.

[0009] Furthermore, the top of the workbench is provided with four mounting seats, which are located on the front and rear sides of the first slot, respectively.

[0010] Furthermore, the rotary drive mechanism also includes two first transmission wheels, one first transmission component, and one first motor. The first motor is mounted on the top of the workbench, one of the first rotating shafts is mounted on the output shaft of the first motor, and the two first transmission wheels are respectively mounted on the two first rotating shafts. The two first transmission wheels are driven by the first transmission component.

[0011] Furthermore, a connecting seat is connected to the top of the workbench, the grinding mechanism is mounted on the connecting seat, and a connecting block is connected to one side of the top of the connecting seat.

[0012] Furthermore, the grinding mechanism includes a No. 3 motor, a No. 3 transmission wheel, a No. 3 transmission component, a No. 3 rotating shaft, and a grinding wheel. The No. 3 motor is mounted on a connecting seat, and the output shaft of the No. 3 motor passes through the connecting seat. There are two No. 3 transmission wheels, which are driven by the No. 3 transmission component. The two No. 3 transmission wheels are respectively mounted on the output shaft of the No. 3 motor and the No. 3 rotating shaft. One end of the No. 3 rotating shaft passes through a connecting block to mount the grinding wheel.

[0013] Furthermore, the mobile drive mechanism includes two second transmission wheels, one second transmission component, one second motor, and two second rotating shafts. Both ends of the two second rotating shafts can be rotatably mounted on the mounting base. One of the second rotating shafts is mounted on the output shaft of the second motor, and the two second transmission wheels are respectively mounted on the two second rotating shafts. The two second transmission wheels are driven by the second transmission component.

[0014] Furthermore, the second transmission component is located in the first slot, and multiple stops are provided on the second transmission component. The length of the second transmission component between every two stops is greater than the length of the piston rod. The stops are located between the two rotating cylinders.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This grinding device for shock absorber piston production places the piston rod directly between two rotating cylinders. The rotating cylinders rotate and friction causes the piston rod to rotate, replacing the rotation function of the existing fixed mechanism. At the same time, the stop block pushes the piston rod to move towards the fixed grinding mechanism. The grinding operation can be carried out simultaneously with the rotation and movement of the piston rod without the need for the left and right translation grinding mechanism. It can continuously grind the piston rod without stopping the machine, effectively improving the overall grinding efficiency.

[0017] This grinding device for shock absorber piston production pushes the piston rod towards the grinding mechanism and into contact with the grinding wheel for grinding. It can also pause the No. 2 motor to intensify grinding at specific locations, achieving the dual advantages of "continuity" and "precision" in the overall grinding of the piston rod. It can rely on overall automatic continuous grinding to ensure batch processing efficiency, and can flexibly control the grinding position and duration according to actual needs, greatly improving the targeting of operations and operational flexibility.

Detailed Implementation

[0024] The present invention will be further described below with reference to the embodiments.

[0025] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0026] Please see Figure 1-5 This utility model provides a grinding device for the production of shock absorber pistons, including a worktable 10.

[0027] The top of the worktable 10 has a slot 101. Four mounting seats 110 are provided on the top of the worktable 10. The four mounting seats 110 are located on the front and rear sides of both ends of the slot 101. A rotary drive mechanism is arranged horizontally on the top of the worktable 10. The rotary drive mechanism is located symmetrically in the slot 101. A grinding mechanism is provided on the top of the worktable 10 and behind the rotary drive mechanism. A moving drive mechanism is provided inside the slot 101. The rotary drive mechanism is located above the moving drive mechanism.

[0028] The rotary drive mechanism includes two rotating cylinders 210, two primary rotating shafts 220, two primary transmission wheels 230, a primary transmission component 240, and a primary motor 250. The primary motor 250 is mounted on the right side of the top of the worktable 10. One of the primary rotating shafts 220 is mounted on the output shaft of the primary motor 250. The two primary transmission wheels 230 are respectively mounted on the two primary rotating shafts 220. The two primary transmission wheels 230 are driven by the primary transmission component 240. Both ends of the two primary rotating shafts 220 are rotatably mounted on the mounting base 1. 10. Two rotating cylinders 210 are respectively mounted on two rotating shafts 220. The distance between the two rotating cylinders 210 is less than the diameter of the piston rod 50. The piston rod 50 is placed between the two rotating cylinders 210. The motor 250 is started. The output shaft of the motor 250 drives one of the rotating shafts 220 to rotate. The other rotating shaft 220 rotates under the action of the transmission component 240 and the transmission wheel 230, thereby causing the two rotating cylinders 210 to rotate. The rotating cylinders 210 drive the piston rod 50 to rotate by friction.

[0029] The moving drive mechanism includes two secondary transmission wheels 410, a secondary transmission component 420, a secondary motor 430, and two secondary rotating shafts 440. Both ends of the two secondary rotating shafts 440 are rotatably mounted on the mounting base 110. One secondary rotating shaft 440 is mounted on the output shaft of the secondary motor 430. The two secondary transmission wheels 410 are respectively mounted on the two secondary rotating shafts 440. The two secondary transmission wheels 410 are driven by the secondary transmission component 420, which is located within the primary slot 101. The secondary transmission component 420 is equipped with multiple stops 421, with a secondary drive shaft 440 positioned between every two stops 421. The length of the transmission component 420 is greater than the length of the piston rod 50, and the stop block 421 is set between the two rotating cylinders 210. The output shaft of the second motor 430 rotates, driving one of the second rotating shafts 440 to rotate. The second rotating shaft 440 drives the second transmission wheel 410 and the second transmission component 420 to rotate. The second transmission component 421 drives multiple stops 421 to pass between the two rotating cylinders 210 one by one. The stop block 421 moves to the right, pushing the piston rod 50 to the right, and the piston rod 50 gradually grinds the mechanism. At the same time, the moving drive mechanism controls the piston rod 50 to stop at a suitable position, which allows the grinding mechanism to increase the grinding time of a certain position.

[0030] The top of the workbench 10 is provided with a connecting seat 120 and a connecting block 121. The grinding mechanism includes a third motor 310, a third transmission wheel 320, a third transmission component 330, a third rotating shaft 340, and a grinding wheel 350. The third motor 310 is mounted on the connecting seat 120, and the output shaft of the third motor 310 passes through the connecting seat 120. There are two third transmission wheels 320, which are driven by the third transmission component 330. The two third transmission wheels 320 are respectively mounted on the output shaft of the third motor 310 and the third rotating shaft 340. One end of the third rotating shaft 340 passes through the connecting block 121 to mount the grinding wheel 350. When the third motor 310 is started, the output shaft of the third motor 310 drives the third transmission wheel 320 and the third transmission component 330, causing the third rotating shaft 340 to rotate with the third transmission wheel 320, thereby causing the grinding wheel 350 to rotate.

[0031] The movement speed of the piston rod 50 can be controlled by the moving drive mechanism, or the thickness of the grinding wheel 350 can be increased to ensure that every position of the piston rod 50 is ground by the grinding wheel 350.

[0032] The working principle and usage process of this utility model are as follows: The piston rod 50 is placed stably between two rotating cylinders 210; then the first motor 250 is turned on, which drives the two first rotating shafts 220 and the rotating cylinders 210 to rotate through the first transmission wheel 230 and the first transmission component 240, so that the piston rod 50 rotates stably; the third motor 310 is turned on, which drives the third rotating shaft 340 and the grinding wheel 350 to rotate at high speed through the third transmission wheel 320 and the third transmission component 330; then the second motor 430 is turned on, which drives the stop block 421 to move with the help of the second transmission wheel 410 and the second transmission component 420, pushing the piston rod 50 to move towards the grinding mechanism and to contact the grinding wheel 350 for grinding. The second motor 430 can be paused to strengthen the grinding of specific positions.
