Description

Technical Field

[0001] This utility model relates to a piston surface treatment device, belonging to the field of piston surface treatment technology. Background Technology

[0002] In modern industry, dampers, as key devices that effectively absorb and dissipate vibration energy, are widely used in many important fields such as construction, bridges, machinery, and transportation. Their performance directly affects the stability, safety, and service life of the entire system. The piston, as the core moving component inside the damper, plays a decisive role in the overall performance of the damper. During damper operation, the piston undergoes high-frequency, high-load reciprocating motion within the cylinder, resulting in the piston surface continuously enduring severe friction, wear, and complex fluid impact forces. Simultaneously, the working environment of dampers is often harsh, potentially facing drastic temperature changes, high humidity, and corrosive media, placing extremely high demands on the wear resistance, corrosion resistance, fatigue resistance, and lubrication performance of the piston surface. Therefore, specialized processing equipment is necessary to polish the piston surface to ensure it meets the operating requirements of the damper.

[0003] Although the existing processing device can complete the grinding operation of the damper piston surface, there are two obvious shortcomings in actual operation: First, the fixing of the damper piston requires manual operation by the staff. This process not only consumes a lot of time, but also directly increases the overall processing time of the device, which seriously restricts the improvement of work efficiency and thus makes the working efficiency of the processing device low.

[0004] On the other hand, the debris generated during grinding needs to be manually cleaned by staff, which increases the operational burden and causes inconvenience in actual use, greatly reducing the ease of use of the device and thus making the processing device less convenient to use. Utility Model Content

The vertical cross-section of each sliding frame is T-shaped. The limiting groove passes through the middle of the frame groove. The cross-section of the limiting groove is cross-shaped. The outer surfaces of the two clamping frames on opposite sides are in contact with the inner walls of the two sliding frames.

[0023] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0024] Example 1

[0025] This utility model provides a piston surface treatment device.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The system includes a frame 1, with a frame groove 2 in the middle of the frame 1, providing space for the placement of the collection box 17. Several through grooves 3 are provided at the upper end of the frame groove 2, and limiting grooves 4 are provided in the middle of the several frame grooves 2. A support frame 5 is fixed to the rear side of the upper end of the frame 1. A cylinder 6 is fixed to the upper end of the support frame 5. A fixed frame 7 is fixed to the driving end of the cylinder 6. A drive motor 8 is fixed to the lower end of the fixed frame 7. A flexible grinding disc 9 is fixed to the driving end of the drive motor 8. The flexible grinding disc 9 is usually made of elastic materials such as polyurethane, rubber, and nylon. These materials give the grinding disc good flexibility and elasticity, allowing it to adaptively adjust according to the shape and contour of the workpiece surface to achieve a better fit. A connecting structure is provided in the middle of the fixed frame 7. The connecting structure includes a fixed block 10. Both ends of the fixed block 10 are rotatably connected to a connecting frame 11. The other ends of the two connecting frames 11 are rotatably connected to a sliding frame 12. A clamping frame 13 is detachably installed in the middle of the two sliding frames 12 by bolts.

[0027] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that the middle of the fixing block 10 is fixed to the middle of the fixing frame 7. The cross section of the fixing block 10 is set in an I-shape. The two connecting frames 11 are rotatably connected to the two ends of the fixing block 10 at opposite ends and rotatably connected to the upper ends of the two sliding frames 12 at near ends. The outer surfaces of the two sliding frames 12 are slidably connected to the inner walls on both sides of the limiting groove 4. The vertical cross section of each sliding frame 12 is set in a T-shape. The limiting groove 4 passes through the middle of the frame groove 2 and has a cross-shaped cross section. The outer surfaces of the two clamping frames 13 at opposite ends are in contact with the inner walls of the two sliding frames 12. The outer surfaces of the two clamping frames 13 are slidably connected to the inner walls on both sides of the frame 1. The middle of the fixing frame 7 is fixed to the driving end of the cylinder 6. The lower end of the fixing frame 7 is fixed to the housing of the drive motor 8. The middle of the flexible grinding disc 9 is fixed to the driving end of the drive motor 8. The outer surface of the flexible grinding disc 9 is in contact with the outer surfaces of the two connecting frames 11.

[0028] In use, this invention works as follows: A cylinder 6 drives a fixed frame 7 to move, which in turn moves a drive motor 8 fixed at the lower end of the fixed frame 7 and a fixed block 10 in the middle. The moving fixed block 10, through a connecting frame 11 rotatably connected at both ends, drives two sliding frames 12 to slide in opposite directions under the constraint of a limiting groove 4 in the middle of the frame 1. The two sliding frames 12 then move in opposite directions through a clamping frame 13 detachably connected by bolts, causing several rubber pads 14 fixed on adjacent sides of the clamping frame 13 to move in opposite directions synchronously. When the flexible grinding disc 9 contacts the damper piston, the two clamping frames 13 move the rubber pads 14 closer together, completing the automatic clamping of the damper piston. At this time, the drive motor 8 is activated, and the flexible grinding disc 9 fixed at its drive end rotates accordingly, thus grinding the surface of the damper piston. This process achieves automatic clamping, eliminating the need for manual operation and improving the working efficiency of the processing device.

[0029] Example 2

[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 An automatic cleaning and collection function has been added based on Embodiment 1;

[0031] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that connecting blocks 15 are fixed on both sides of the two clamping frames 13, and brush holders 16 are fixed at the lower ends of the two connecting blocks 15. A collection box 17 is provided on the inner wall of the frame groove 2. The near ends of each pair of adjacent connecting blocks 15 are fixed on both sides of one of the clamping frames 13. The lower end of each connecting block 15 is fixed to the upper end of each brush holder 16. The bristles of each brush holder 16 are attached to the upper surface of the frame body 1. The outer surface of the collection box 17 is in contact with the inner wall of the frame groove 2.

[0032] In use, this invention works as follows: A cylinder 6 drives the fixed frame 7 to move, causing the fixed block 10 connected to the fixed frame 7 to drive two sliding frames 12 via two connecting frames 11, which in turn causes the two clamping frames 13 to move in opposite directions. The reverse-moving clamping frames 13 drive the connecting blocks 15 fixed on both sides to move synchronously, and the connecting blocks 15 push the brush frame 16 fixed in the middle to move. During the movement, the brush frame 16 sweeps away the grinding debris on the surface of the frame 1. The swept debris falls into the collection box 17 in the frame groove 2 through the through slot 3. This process achieves automatic cleaning and collection, eliminating the need for manual operation and providing convenience for workers, thus improving the ease of use of the processing device.
