Description

Technical Field

[0001] This utility model belongs to the field of piston surface polishing technology, and in particular relates to a piston surface polishing device. Background Technology

[0002] The damper piston is the core moving component of the damper. Its function is to convert the vibrational kinetic energy of the system into heat energy or other forms of energy consumption through interaction with the damping medium (such as hydraulic oil, gas or viscous fluid), thereby suppressing vibration and buffering impact. The damper piston is usually composed of four parts: body, seal, guide ring and connection interface. It is mostly cylindrical (to fit the hydraulic cylinder). In some special scenarios (such as rotary dampers), annular or asymmetrical structures are used. The diameter is usually clearance-fitted with the inner diameter of the damper cylinder, and the length depends on the damping stroke.

[0003] When polishing the damper piston, the most common method is mechanical polishing. This involves using a polishing wheel, such as a wool wheel, cloth wheel, or sandpaper, to rotate at high speed, combined with the cutting action of polishing paste, such as cerium oxide or diamond powder, to remove microscopic protrusions on the surface and reduce roughness. However, manual polishing cannot control the piston to be polished evenly, and some areas may be over-polished. In addition, manual polishing is physically demanding and troublesome. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a piston surface polishing device to more accurately resolve the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a piston surface polishing device, including a base plate, a clamping assembly on the upper surface of the base plate, a first mounting plate fixedly connected to one side of the upper surface of the base plate located on the clamping assembly, a first screw threadedly connected to the first mounting plate, a polishing plate provided at one end of the first screw, and a second mounting plate fixedly connected to the upper surface of the base plate located on the other side of the clamping assembly, with two polishing rods provided on the second mounting plate.

[0007] In one example, the clamping assembly includes a vertical plate fixedly connected to a base plate. The upper surface of the base plate is provided with a square through groove, in which a sliding plate is slidably connected. Both the sliding plate and the vertical plate are provided with circular through grooves, in which rotating rings are rotatably connected. The inner side of the rotating rings is conical.

[0008] In one example, a support frame is fixedly connected to the lower surface of the base plate, and a support plate is fixedly connected to the lower surface of the base plate. A servo motor is installed on one side of the support plate, and the main shaft of the servo motor is fixedly connected to a second screw. The second screw passes through the sliding plate and is threadedly connected to the sliding plate.

[0009] In one example, a fixing plate is fixedly connected to the upper surface of the base plate, a drive motor is installed on one side of the fixing plate, the main shaft of the drive motor is fixedly connected to a first pulley, the fixing plate is located on one side of the vertical plate, a second pulley is fixedly connected to the outer side of the rotating ring on the vertical plate, and a belt is connected between the first pulley and the second pulley.

[0010] In one example, two guide rods are slidably connected to the first mounting plate, the guide rods pass through the first mounting plate, one end of the guide rod is fixedly connected to a support plate, the polishing plate is fixed to one side of the support plate, and the first screw is rotatably connected to the support plate.

[0011] In one example, the second mounting plate has a square through groove on one side, and two sliding seats are slidably connected in the square through groove. A crossbar is fixedly connected to each of the two sliding seats, and a polishing rod is fixed to the crossbar. A fixing block is fixedly connected to one side of each sliding seat, and a fastening screw is threaded onto the fixing block.

[0012] The piston surface polishing device proposed in this utility model can bring the following beneficial effects:

[0013] Firstly, by setting up a polishing rod and a polishing plate, which are located on both sides of the piston, the polishing plate is relatively long and covers a large area. The first screw can be directly rotated to make the polishing plate contact the outer side of the piston. The piston is cylindrical and consists of an outer arc surface and two circular surfaces on both sides. Then, the polishing rod is moved to contact the circular surfaces on both sides of the piston. After that, the piston rod and the piston are rotated, and polishing is performed through contact between the polishing rod and the polishing plate. This allows the device to adapt to polishing pistons of different sizes and models, increasing the range of applications of the device and making it more flexible.

[0014] Secondly, by setting up rotating rings, the piston rod and piston are placed together between two rotating rings. Then, the servo motor is started, and the second screw rotates to drive the sliding plate to move closer to the piston rod, so that the two ends of the piston rod are inserted into the rotating rings on both sides and abut against the conical surface on the inner side of the rotating ring. The conical surface can squeeze and fix piston rods of different diameters, further increasing the application range of the device. Attached Figure Description

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0021] like Figures 1-4 As shown, an embodiment of this utility model proposes a piston surface polishing device, including a base plate 1. A clamping assembly 2 is provided on the upper surface of the base plate 1. A first mounting plate 3 is fixedly connected to one side of the upper surface of the base plate 1, located on the clamping assembly 2. A first screw 4 is threadedly connected to the first mounting plate 3. A polishing plate 5 is provided at one end of the first screw 4. A second mounting plate 6 is fixedly connected to the other side of the upper surface of the base plate 1, located on the clamping assembly 2. Two polishing rods 7 are provided on the second mounting plate 6. In use, the piston rod is clamped and fixed by the clamping assembly 2, and the piston is fixed on the piston rod. Different pistons have different installation positions. In order for the device to be able to polish the surface of the piston rod, the device is designed to polish the piston rod. The piston at different positions on the piston rod is polished using a polishing plate 5 and a polishing rod 7, located on opposite sides of the piston. The polishing plate 5 is longer and covers a larger area, allowing direct rotation of the first screw 4 to bring the polishing plate 5 into contact with the outer side of the piston. The piston is cylindrical, consisting of an outer arc surface and two circular surfaces on either side. The polishing rod 7 is then moved to contact the circular surfaces on both sides of the piston. After rotating the piston rod and piston, polishing is performed through contact between the polishing rod 7 and the polishing plate 5. This allows the device to be adapted to polishing pistons of different sizes and models, increasing its applicability and flexibility.

[0022] like Figure 1 and Figure 2As shown, the clamping assembly 2 includes a vertical plate 21, which is fixedly connected to the base plate 1. The upper surface of the base plate 1 has a square through groove, within which a sliding plate 22 is slidably connected. Both the sliding plate 22 and the vertical plate 21 have circular through grooves, within which a rotating ring 23 is rotatably connected. The inner side of the rotating ring 23 is conical. A support frame 8 is fixedly connected to the lower surface of the base plate 1, and a support plate 9 is fixedly connected to the lower surface of the base plate 1. A servo motor 10 is mounted on one side of the support plate 9. The spindle of the servo motor 10 is fixedly connected to a second screw 11, which passes through the sliding plate 22 and is threadedly connected to it. When the piston rod and piston are in contact, place them together between the two rotating rings 23. Then, the servo motor 10 starts, and the second screw 11 rotates to drive the sliding plate 22 to move closer to the piston rod, so that both ends of the piston rod are inserted into the rotating rings 23 on both sides and abut against the conical surface on the inner side of the rotating rings 23. The conical surface can squeeze and fix piston rods of different diameters, further increasing the range of applications of the device. At the same time, a rubber pad is fixed on the conical surface to increase friction. After the two rotating rings 23 squeeze and fix the piston rod, adjust the position of the polishing plate 5 and the polishing rod 7, and then rotate the piston rod and piston to polish, which is more convenient and labor-saving.

[0023] like Figure 2 and Figure 3 As shown, a fixing plate 12 is fixedly connected to the upper surface of the base plate 1. A drive motor 13 is installed on one side of the fixing plate 12. The main shaft of the drive motor 13 is fixedly connected to the first pulley 14. The fixing plate 12 is located on one side of the vertical plate 21. A second pulley 15 is fixedly connected to the outer side of the rotating ring 23 on the vertical plate 21. A belt is connected between the first pulley 14 and the second pulley 15. During polishing, the drive motor 13 is started, which drives a rotating ring 23 to rotate, thereby causing the piston rod and piston to rotate for polishing.

[0024] like Figure 3 and Figure 4 As shown, two guide rods 16 are slidably connected to the first mounting plate 3. The guide rods 16 pass through the first mounting plate 3, and one end of the guide rod 16 is fixedly connected to the support plate 17. The polishing plate 5 is fixed to one side of the support plate 17. The first screw 4 is rotatably connected to the support plate 17. The polishing plate 5 is relatively long and has a long coverage area. Even if the piston is installed at different positions on the piston rod, when the first screw 4 rotates, it pushes the support plate 17 and the polishing plate 5 to move, and they will contact the piston, thus facilitating the contact polishing of the outer arc surface of the piston.

[0025] like Figure 3 and Figure 4As shown, a square through groove is provided on one side of the second mounting plate 6. Two sliding seats 18 are slidably connected in the square through groove. A crossbar 19 is fixedly connected to each of the two sliding seats 18. The polishing rod 7 is fixed to the crossbar 19. A fixing block 20 is fixedly connected to one side of each sliding seat 18. A fastening screw is threaded onto the fixing block 20. Pushing the sliding seat 18 to move it closer to the piston from both sides of the piston, the polishing rod 7 is L-shaped and wraps around the two sides of the crossbar 19. After the two polishing rods 7 contact the two sides of the piston, the fastening screw is rotated to fix the position of the two sliding seats 18. By setting the sliding seats 18, the polishing rod 7 can be moved to use the piston in different positions.

[0026] Working principle: The piston rod and piston are placed together between two rotating rings 23. Then, the servo motor 10 is started, and the second screw 11 rotates to drive the sliding plate 22 to move closer to the piston rod, so that the two ends of the piston rod are inserted into the rotating rings 23 on both sides and abut against the conical surface on the inner side of the rotating rings 23. The two rotating rings 23 press and fix the piston rod. When the first screw 4 rotates, it pushes the support plate 17 and the polishing plate 5 to move, and they will both come into contact with the piston, thus facilitating the contact polishing of the outer arc surface of the piston. It pushes the sliding seat 18 to move and approach the piston from both sides. The polishing rod 7 is L-shaped and wraps around the two sides of the crossbar 19. After the two polishing rods 7 contact the two sides of the piston, the fastening screw is rotated to fix the position of the two sliding seats 18. The drive motor 13 is started, driving one rotating ring 23 to rotate, thus causing the piston rod and piston to rotate for polishing.
