Description

Technical Field

[0001] This utility model relates to the field of shock absorber component processing technology, specifically a polishing device for shock absorbers in new energy vehicles. Background Technology

[0002] Shock absorbers play a crucial role in automotive suspension systems, buffering vibrations to ensure smooth vehicle operation and enhance passenger comfort. When a car travels on uneven roads, the impact from the ground first reaches the springs, and then the shock absorbers further absorb these impacts, preventing the springs from rebounding. This process ensures vehicle stability and reduces bumps and swaying. After production, the piston rods and cylinders of the shock absorbers may have burrs on their surfaces, requiring polishing before assembly.

[0003] A polishing device for shock absorbers of new energy vehicles, disclosed in publication CN 222711755 U, includes a base and a mounting seat on top of it. A motor base is located on the side wall of the base, and a slide block is slidably mounted on the motor base. A drive mechanism is mounted on the slide block. This invention uses the drive mechanism to drive a fixed roller to rotate via belt transmission. The fixed roller drives the polishing belt to rotate, bringing the workpiece close to the polishing belt. The polishing belt adheres tightly to the backing plate, ensuring a flat and uniform polishing surface. Furthermore, the heat generated by friction between the polishing belt and the backing plate can be quickly dissipated through a bent heat dissipation plate, thereby reducing the temperature of the polishing belt and extending its service life. During this process, the tension of the transmission belt is controlled by adjusting the nut b and the pull rod a, improving its transmission efficiency. The tension of the polishing belt is controlled by adjusting the pull rod b and the nut a, and the elastic element can automatically adjust if the tension of the polishing belt is too high or too low.

[0004] However, the above-mentioned device still has some shortcomings in use. It requires manual hand-grinding of the shock absorber components. When manually grinding the components, the operator is easily injured due to tool slippage or component rotation. Furthermore, it is difficult to ensure the consistency of grinding force and direction, which can easily lead to uneven surface grinding, excessive local wear, or grinding blind spots. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a polishing device for shock absorbers in new energy vehicles. It solves the problems of manually holding shock absorber components for polishing, which can easily lead to operator injury due to tool slippage or component rotation. Furthermore, it is difficult to ensure the consistency of polishing force and direction, which can easily result in uneven surface polishing, excessive local wear, or polishing blind spots.

[0006] This utility model provides the following technical solution: a polishing device for shock absorbers of new energy vehicles, including a base plate, a set of electric push rods fixedly installed on the upper surface of the base plate, a support plate fixedly connected between the output ends of the two electric push rods, a screw rod rotatably connected to the upper surface of the support plate, a screw sleeve threaded onto the surface of the screw rod, an installation box fixedly connected to the side of the screw sleeve, the interior of the installation box is hollow and two movable grooves are opened on the surface, a bidirectional lead screw rotatably connected between the top and bottom walls of the installation box, two lead screw sleeves threaded onto the surface of the bidirectional lead screw, one end of each of the two lead screw sleeves extends to the outside of the installation box and is fixedly connected to a connecting plate, and clamps are rotatably connected to the opposite sides of the two connecting plates;

[0007] Two vertical rods are fixedly connected to the upper surface of the base plate. Each of the two vertical rods has a set of through holes on its surface. A connecting rod is slidably fitted inside each of the through holes. A fixing plate is fixedly connected to one end of the four connecting rods. A grinding block is installed on the fixing plate. A spring is fitted on the surface of each connecting rod.

[0008] Preferred technical solution 1: A sliding rod is fixedly connected to the upper surface of the support plate, and a sliding sleeve is slidably sleeved on the surface of the sliding rod, and the sliding sleeve is fixedly connected to the threaded sleeve.

[0009] Preferred technical solution 2: A top plate is fixedly connected to the top of the slide rod, the screw is rotatably connected to the top plate, a first motor is fixedly connected to the upper surface of the top plate, and the output end of the first motor passes through the top plate and is fixedly connected to the screw.

[0010] Preferred technical solution 3: A limiting rod is fixedly connected between the top and bottom walls of the mounting box, and two limiting sleeves are slidably sleeved on the surface of the limiting rod, with the two limiting sleeves respectively fixedly connected to the two connecting plates.

[0011] Preferred technical solution four: A second motor is fixedly connected to the upper surface of the connecting plate located above, and the output end of the second motor passes through the connected connecting plate and is fixedly connected to the corresponding clamping plate.

[0012] Preferred technical solution five: Two sliding grooves are formed on the upper surface of the base plate, and a slider is slidably fitted inside each of the two sliding grooves. Both sliders are fixedly connected to the support plate.

[0013] Compared with existing technologies, this utility model provides a polishing device for shock absorbers of new energy vehicles, which has the following beneficial effects: In use, the shock absorber cylinder or piston rod is placed between two clamping plates. Then, by rotating the bidirectional lead screw, two lead screw sleeves and two clamping plates are driven to clamp and fix the cylinder. Then, the extension of the electric push rod drives the support plate, mounting box, and cylinder to move, bringing the cylinder close to and tightly against the polishing block. Then, the rotation of the second motor drives the clamping plates and cylinder to rotate, and the polishing block polishes the surface of the cylinder. Simultaneously, the rotation of the first motor drives the screw to rotate, thereby moving the screw sleeve, mounting box, and cylinder up and down, thus polishing different parts of the cylinder, making the polishing more comprehensive. Furthermore, the connecting rod and spring ensure that the polishing block is always in close contact with the cylinder, resulting in better polishing. This device can clamp and fix the shock absorber components and automatically polish them, eliminating the need for manual handling and avoiding potential dangers. It can also polish different parts of the components, resulting in more comprehensive and better polishing. Attached Figure Description

[0021] Example 2: The difference between this example and Example 1 is that a sliding rod 16 is fixedly connected to the upper surface of the support plate 3, a sliding sleeve 17 is slidably sleeved on the surface of the sliding rod 16, and the sliding sleeve 17 is fixedly connected to the screw sleeve 5.
