Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a clamping device for removing surface defects of a coil spring of an automobile suspension. Background Art

[0002] Automobile suspension springs are elastic elements in automobile suspension, which make elastic connection between the axle and the frame or body, bear and transmit vertical loads, and alleviate and suppress the impact caused by uneven roads.

[0003] In the final stage of production and processing of automobile suspension springs, defects generated on the spring surface during the processing need to be polished and removed. At present, the defects are usually polished with a handheld grinder. At the same time, the suspension spring needs to be rotated during the polishing process to polish different surfaces. However, due to the heavy weight of the suspension spring, the current method of rotating the suspension spring by hand increases the labor intensity of the operator, and the spring needs to be fixed during the polishing process, which makes the operator easily fatigued. Therefore, we propose a clamping device for removing surface defects of automobile suspension coil springs to solve the above problems. Utility Model Content

[0004] The utility model addresses the defects of the prior art method of rotating the suspension spring by hand, which increases the labor intensity of the operator and requires the spring to be fixed during the grinding process, causing the operator to easily become fatigued. A clamping device for removing surface defects of the automobile suspension coil spring is provided.

[0005] The utility model is achieved through the following technical solutions:

[0006] A clamping device for removing surface defects of a coil spring of an automobile suspension comprises a base, a support column is fixed to the base, a support seat is fixed to the top end of the support column, and clamping plates are hinged on both sides of the support seat;

[0007] A support plate is sleeved on the support column, and the support plate and the support column are slidably matched, and a hydraulic cylinder is provided at the bottom end of the support plate for pushing the support plate to slide up and down, and both ends of the support plate are hinged with connecting rods, and the top ends of the two connecting rods are hingedly connected to the outer walls of the two clamping plates respectively;

[0008] The inner walls of the two splints and the upper surface of the support seat are both rotatably installed with multiple first rotating rollers, and the upper surface of the support seat is also provided with a second rotating roller, and a second pulley is fixed to one end of the second rotating roller. A servo motor is installed at the bottom end of the support seat, and a first pulley is fixed to the outer end of the servo motor. The first pulley and the second pulley are connected by a V-belt.

[0009] In a preferred embodiment of the present invention, the upper surface of the support seat and the two clamping plates are both arc-shaped, and mounting shafts are fixed at both ends of the support seat. One side of the clamping plate is rotatably mounted on the mounting shaft, which facilitates clamping of the suspension spring and improves stability after clamping.

[0010] In a preferred embodiment of the present invention, the number of the first rotating rollers on the upper surface of the support seat is even, and the second rotating roller is located in the middle of the upper surface of the support seat, and a rubber layer is provided on the surface of the second rotating roller. The setting of the rubber layer increases the friction between the second rotating roller and the suspension spring, making it easier for the second rotating roller to drive the suspension spring to rotate. At the same time, when the second rotating roller stops, the suspension spring can be stopped in time.

[0011] In a preferred embodiment of the present invention, a reducer is provided on the output shaft of the servo motor, and the first pulley is fixed on the output shaft of the reducer. The speed at which the servo motor drives the suspension spring to rotate is slowed down by the setting of the reducer.

[0012] In a preferred embodiment of the present invention, the heights of the first rotating roller and the second rotating roller exposed from the clamping plate and the support seat are the same, which increases the contact area with the suspension spring, thereby improving the stability of the suspension spring during rotation when the first rotating roller and the second rotating roller rotate.

[0013] The beneficial effects of the utility model are:

[0014] This device drives the clamping plate to rotate through the hydraulic cylinder to clamp and fix the suspension spring, and can grind the defects on the spring surface from above. At the same time, the rotation of the servo motor can drive the spring to rotate, which is convenient for grinding different surfaces of the spring, avoiding manual support and rotation of the spring, and thus reducing the labor intensity of the operator.

The upper surface of the support seat 3 and the two clamping plates 4 are both arc-shaped, and mounting shafts 7 are fixed to both ends of the support seat 3. One side of the clamping plate 4 is rotatably mounted on the mounting shaft 7, facilitating clamping of the suspension spring and improving stability after clamping.

[0021] Among them, a support plate 8 is sleeved on the support column 2, and the support plate 8 is slidably matched with the support column 2, and a hydraulic cylinder 10 is provided at the bottom end of the support plate 8 for pushing the support plate 8 to slide up and down. There are two hydraulic cylinders 10, and the hydraulic cylinders 10 are fixedly installed on the base 1, and both ends of the support plate 8 are hinged with connecting rods 9, and the top ends of the two connecting rods 9 are respectively hingedly connected to the outer walls of the two splints 4. The operation of the hydraulic cylinder 10 drives the support plate 8 to move up and down, and then drives the two splints 4 to open or close;

[0022] Specifically, a plurality of first rotating rollers 5 are rotatably mounted on the inner walls of the two clamping plates 4 and the upper surface of the support seat 3, and a second rotating roller 6 is also provided on the upper surface of the support seat 3. The first rotating rollers 5 and the second rotating rollers 6 are exposed at the same height from the clamping plates 4 and the support seat 3, thereby increasing the contact area with the suspension spring, thereby improving the stability of the suspension spring during rotation when the first rotating rollers 5 and the second rotating rollers 6 rotate;

[0023] At the same time, a second pulley 13 is fixed to one end of the second rotating roller 6, a servo motor 11 is installed at the bottom end of the support seat 3, a first pulley 12 is fixed to the outer end of the servo motor 11, the first pulley 12 and the second pulley 13 are connected by a V-belt, a reducer is provided on the output shaft of the servo motor 11, the first pulley 12 is fixed on the output shaft of the reducer, and the speed of the servo motor 11 driving the suspension spring to rotate is slowed down by the setting of the reducer.

[0024] It should be noted that the number of the first rotating rollers 5 on the upper surface of the support seat 3 is an even number, and the second rotating roller 6 is located in the middle of the upper surface of the support seat 3, and a rubber layer is provided on the surface of the second rotating roller 6. The setting of the rubber layer increases the friction between the second rotating roller 6 and the suspension spring, making it easier for the second rotating roller 6 to drive the suspension spring to rotate. At the same time, when the second rotating roller 6 stops, the suspension spring can be stopped in time.

[0025] In this embodiment, when grinding the suspension spring, the spring is placed on the support seat 3, the hydraulic cylinder 10 is turned on, and the support plate 8 is driven upward by the hydraulic cylinder 10. The support plate 8 pushes the two clamping plates 4 to rotate toward the spring through the connecting rod 9 to clamp the spring;
