Description

Technical Field

[0001] This utility model relates to the field of piston rod precision grinding technology, specifically a piston rod surface precision grinding machine. Background Technology

[0002] Motorcycle shock absorbers are an important component of motorcycles, and the piston rod, as the core component of the shock absorber, directly affects the performance and service life of the shock absorber due to its surface quality. The piston rod surface needs to have high smoothness and precision to ensure the sealing performance and smooth operation of the shock absorber.

[0003] Patent publication number "CN220561096U" discloses a "piston rod surface fine grinding machine," comprising a base, a storage tray, and a rod. The storage tray is positioned above the base to support the rod, which is placed on top of the tray. A centering clamp is positioned above the storage tray, with the clamp angled evenly around the center of the tray to provide centering positioning for the rod. A first spring is located inside the centering clamp to provide an outward pushing and restoring force, and a position synchronization control mechanism is located inside the centering clamp. This piston rod surface fine grinding machine, through the centering clamp, can fix the rod in the center of the storage tray, allowing it to maintain stable rotation. This, combined with the grinding block, achieves the grinding effect. The centering clamp is controlled by a second telescopic controller, which is unaffected by the rotation of the storage tray, resulting in more stable operation and improved fine grinding quality.

[0004] The aforementioned patent does not include an effective dust removal device. Metal shavings generated during the grinding process will scatter throughout the equipment and the working environment, which not only affects the normal operation of the equipment but may also pose safety hazards to operators. In addition, it increases the workload of subsequent cleaning and maintenance. Therefore, there is a problem that it is not convenient to clean the shavings generated during the grinding process.

[0005] To address these issues, this invention provides a piston rod surface grinding machine. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a piston rod surface fine grinding machine, which solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a piston rod surface polishing machine, comprising a base, a polishing mechanism fixedly connected to the upper surface of the base, a clamping mechanism fixedly connected to the upper surface of the polishing mechanism, the polishing mechanism including a fixed frame fixedly connected to the upper surface of the base, a lifting frame slidably connected to the outer surface of the fixed frame, a second electric telescopic rod fixedly connected to the outer surface of the lifting frame, a moving plate fixedly connected to the output end of the second electric telescopic rod, a dust collection frame and a polishing block fixedly connected to the outer surface of the moving plate, and a dust collection box and a vacuum pump fixedly connected to the upper surface of the lifting frame, a sealing plate detachably connected to the outer surface of the dust collection box by bolts, the clamping mechanism including a first electric telescopic rod fixedly connected to the upper surface of the fixed frame, a lifting plate fixedly connected to the output end of the first electric telescopic rod, a turntable rotatably connected to the lower surface of the lifting plate, a piston rod attached to the lower surface of the turntable, and a rotating frame attached to the lower surface of the piston rod, the rotating frame rotatably connected to the upper surface of the base.

[0008] Furthermore, the polishing mechanism also includes a second limiting rod fixedly connected to the outer surface of the moving plate, the outer surface of the second limiting rod being slidably connected to the outer surface of the lifting frame, and the dust collection frame adopting an arc-shaped structure.

[0009] By adopting the above technical solution, the second limiting rod plays a limiting and guiding role in the movement of the moving plate, preventing the moving plate from deviating during the movement and ensuring the accurate grinding position of the grinding block; the arc-shaped dust collection frame can better fit the outer surface of the piston rod, improve the adsorption effect of grinding debris, and reduce debris overflow.

[0010] Furthermore, the air intake of the vacuum pump is fixedly connected to the inner wall of the dust collection box, and a filter screen is fixedly connected to the air intake of the vacuum pump. A dust collection pipe is fixedly connected to the inner wall of the dust collection box, and the other end of the dust collection pipe is connected to the inner wall of the dust collection frame. Multiple sets of air intake holes are opened on the outer surface of the dust collection frame.

[0011] By adopting the above technical solution, the filter screen can filter out the sucked-in debris, preventing debris from entering the vacuum pump and causing damage, thus extending the service life of the vacuum pump; the suction pipe connects the suction frame and the suction box to form a complete suction path, ensuring that debris can smoothly enter the suction box; multiple sets of suction holes increase the suction area, improve suction efficiency, and further ensure the debris collection effect.

[0012] Furthermore, the grinding mechanism also includes a second servo motor fixedly connected to the inner wall of the base. The output shaft of the second servo motor is fixedly connected to a one-way threaded rod. The one-way threaded rod is rotatably connected to the outer surface of the fixed frame, and the outer surface of the one-way threaded rod is threadedly connected to the outer surface of the lifting frame.

[0013] By adopting the above technical solution, the rotation of the one-way threaded rod is powered by the second servo motor. The rotation of the one-way threaded rod drives the lifting frame to move up and down along the fixed frame, thereby realizing the precise adjustment of the height of the grinding mechanism, meeting the grinding needs of piston rods of different lengths, and the adjustment process is stable and reliable.

[0014] Furthermore, the clamping mechanism includes a first servo motor fixedly connected to the inner wall of the base, the output shaft of the first servo motor fixedly connected to the lower surface of the rotating frame, and a control panel fixedly connected to the outer surface of the base, and a heat dissipation grille fixedly connected to the outer surface of the base.

[0015] Using the above technical solution, the first electric telescopic rod can drive the lifting plate to move up and down, which makes it easy to press the piston rod onto the rotating frame and achieve a stable clamping of the piston rod; the turntable is rotatably connected to the lifting plate, so that when the piston rod rotates with the rotating frame, the turntable can rotate with it, avoiding obstruction to the rotation of the piston rod and ensuring uniform grinding.

[0016] Furthermore, a bidirectional threaded rod is rotatably connected to the inner wall of the rotating frame. One end of the bidirectional threaded rod passes through the outer surface of the rotating frame and is fixedly connected to a knob. The outer surface of the bidirectional threaded rod is threadedly connected to the outer surface of the clamping block. A first limiting rod is fixedly connected to the upper surface of the lifting plate. The first limiting rod is slidably connected to the outer surface of the fixed frame.

[0017] With the above technical solution, the control panel allows operators to easily set and adjust various parameters of the equipment, making operation convenient; the heat dissipation grille helps dissipate heat from components such as the motor inside the base, preventing excessive temperature from affecting the normal operation and service life of the equipment; the bidirectional threaded rod rotates under the drive of the knob, which can move the clamping blocks closer or further apart, thereby adapting to piston rods of different diameters and achieving stable clamping of the piston rods; the first limit rod plays a limiting and guiding role in the up and down movement of the lifting plate, preventing the lifting plate from shifting during movement and ensuring clamping stability.

[0033] Reference Figures 1 to 4 In one aspect of this embodiment, the grinding mechanism 3 further includes a second servo motor 309 fixedly connected to the inner wall of the base 1. The output shaft of the second servo motor 309 is fixedly connected to a one-way threaded rod 308.

[0035] Reference Figures 1 to 4 In one aspect of this embodiment, a bidirectional threaded rod 206 is rotatably connected to the inner wall of the rotating frame 209. One end of the bidirectional threaded rod 206 passes through the outer surface of the rotating frame 209 and is fixedly connected to a knob 207.

When no external force is applied, self-locking can be achieved by relying on friction.

[0036] Working principle: First, the operator places the motorcycle shock absorber piston rod body 4 on the rotating frame 209. Turning the knob 207 drives the bidirectional threaded rod 206 to rotate, causing the clamping blocks 205 to move closer together, clamping and fixing the lower end of the piston rod body 4. Then, the operator starts the first electric telescopic rod 201 via the control panel 5. The first electric telescopic rod 201 drives the lifting plate 203 downwards, causing the turntable 204 to fit against the upper end of the piston rod body 4, further fixing the piston rod body 4. At this time, the first limit rod 202 slides along the fixed frame 311, ensuring the stable movement of the lifting plate 203. Next, according to the length of the piston rod body 4, the operator starts the second servo motor 309 via the control panel 5. The second servo motor 309 drives the unidirectional threaded rod 308 to rotate, causing the lifting frame 305 to move up and down along the fixed frame 311, adjusting the grinding block 313 to a suitable height. After that, the operator starts the second... Two electric telescopic rods 312 drive the moving plate 307 to move, so that the grinding block 313 contacts the surface of the piston rod body 4. At the same time, the vacuum pump 301 is started. The vacuum pump 301 sucks the grinding debris into the dust collection box 302 through the suction pipe 304 and the suction holes on the dust collection frame 306. The filter screen prevents debris from entering the vacuum pump 301. Then, the first servo motor 208 is started, which drives the rotating frame 209 to rotate, thereby rotating the piston rod body 4. The grinding block 313 performs all-round fine grinding on the surface of the piston rod body 4. The turntable 204 rotates synchronously with the piston rod body 4 to ensure smooth grinding. After grinding is completed, each motor and vacuum pump 301 are turned off in sequence. The control panel 5 controls the reset of each component. The knob 207 is turned in the opposite direction to release the clamping block 205 and remove the processed piston rod body 4. Finally, the removable sealing plate 303 is used to clean the debris in the dust collection box 302.
