Description

Technical Field

[0001] The utility model relates to the technical field of brake pads, in particular to a tightening mechanism for grinding brake pads. Background Art

[0002] Automobile brake pads, also known as automobile brake leathers, refer to the friction materials fixed on the brake drum or brake disc that rotates with the wheel. The friction lining and friction lining block bear external pressure and generate friction to achieve the purpose of vehicle deceleration. Automobile brake pads are the main components of automobile wheel braking. In the processing and production of brake pads, the quality requirements are very strict.

[0003] The utility model with the existing authorization announcement number CN202321070724.4 discloses a clamping mechanism for grinding brake pads. By adopting the above technical solution, the fixed base facilitates the installation and fixation of the entire clamping mechanism. The vertical rod provides a stable installation position for the clamping block and the elastic power member. The entire clamping mechanism has a compact and simple structure, and is relatively easy to manufacture and install. In addition, the elastic power member can continuously output the force that drives the clamping block to rotate. Therefore, when the brake pad is driven to rotate by the rotating cylinder, the clamping block can press the brake pad against the outer peripheral side of the rotating cylinder, effectively preventing The brake pad falls under the combined effect of gravity and equipment vibration. The brake pad is not easy to fall off the outer peripheral side of the rotating cylinder and is not easy to get stuck. However, the above technical solution cannot tighten the brake pad according to the size of the brake pad during the process of tightening the brake pad on the rotating cylinder by the clamping block, resulting in certain limitations. In addition, the rotational force of the brake pad causes the clamping block to rotate on the elastic power part to tighten the brake pad to a certain extent, while the torsional force between the clamping block and the elastic power part is relatively small, resulting in certain limitations in the tightening effect.

[0004] Therefore, those skilled in the art have provided a tightening mechanism for grinding brake pads to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

In addition, the arrangement of the second curved connecting plate greatly increases the clamping time of the clamping structure on the brake pad, thereby increasing the clamping effect. By using the first curved connecting plate, the curved rubber plate, and the second curved connecting plate, the clamping time of the clamping structure and the brake pad can be increased, thereby increasing the clamping effect. The adjusting groove, the supporting plate, the positioning plate, the threaded groove, and the positioning bolt are then conveniently used for brake pads of various sizes and models, thereby effectively increasing the applicable scope of the clamping, thereby avoiding the problem that the brake pad cannot be clamped according to the size of the brake pad. Furthermore, the rotational force of the brake pad causes the clamping block to rotate on the elastic power part to clamp the brake pad to a certain extent, thereby resulting in a relatively short clamping time of the brake pad, thereby reducing the problem of reduced clamping effect.

DETAILED DESCRIPTION

[0021] See also Figure 1-4The clamping mechanism for grinding brake pads includes a rotating cylinder 1, the outer surface of which is clamped with two groups of brake pads 3, a clamping mechanism 2 is arranged on the outer side of the rotating cylinder 1, and the clamping mechanism 2 includes a mounting plate 203, the inner wall of the mounting plate 203 is in contact with the outer surface of the rotating cylinder 1, and the outer surface of the mounting plate 203 is fixedly connected with two fixing plates 6, and the inner wall of each fixing plate 6 is threadedly connected with the inner wall of the rotating cylinder 1 with a fixing bolt 8, and the mounting plate 203 can be conveniently fixed on the rotating cylinder 1 through the fixing plate 6 and the fixing bolt 8, so as to facilitate its installation.

[0022] Two adjustment grooves 204 and a number of identical thread grooves 205 are respectively provided on the upper surface of the mounting plate 203, and a support plate 202 is slidably connected inside each adjustment groove 204, and a positioning plate 206 is fixedly connected to the side of the two support plates 202 that are away from each other, and an inner wall of each positioning plate 206 is threadedly connected to the inner wall of one of the thread grooves 205 with a positioning bolt 207, and a stabilizing plate 5 is fixedly connected to the side of the two support plates 202 that are close to each other, and two adjustment handles 4 are fixedly connected to the outer surface of the stabilizing plate 5, and the position of the support plate 202 can be conveniently adjusted through the stabilizing plate 5 and the adjustment handle 4, thereby facilitating the adjustment of the position of the entire clamping structure.

[0023] The outer surfaces of the two support plates 202 are commonly fixedly connected with an arc plate 201, the inner wall of the arc plate 201 is fixedly connected with four buffer springs 208, a first arc connecting plate 211 is arranged on the outer side of the arc plate 201, a buffer pad 7 is arranged on the outer side of each support plate 202, the outer surface of each buffer pad 7 is fixedly connected to the outer surface of the support plate 202, and the buffer pad 7 can be used to conveniently increase the buffering of the support plate 202 to prevent vibration that makes it inconvenient to use.

[0024] One end of each buffer spring 208 away from the arc plate 201 is fixedly connected to the outer surface of the first arc connecting plate 211, and the outer surface of each buffer spring 208 is fixedly connected to two connecting plates 9. The side faces of each group of connecting plates 9 away from each other are respectively fixedly connected to the inner wall of the arc plate 201 and the outer surface of the first arc connecting plate 211. Through the connecting plates 9, the connection of the buffer spring 208 can be increased to prevent the buffer spring 208 from falling off.

[0025] The inner wall of the first arc-shaped connecting plate 211 is fixedly connected with an arc-shaped rubber plate 210, the inner wall of the arc-shaped rubber plate 210 is fixedly connected with a second arc-shaped connecting plate 209, the inner wall of the second arc-shaped connecting plate 209 is fixedly connected with a slide plate 10, and the outer surface of one group of brake pads 3 is in contact with the outer surface of the slide plate 10. The slide plate 10 can reduce the friction between the second arc-shaped connecting plate 209 and the brake pads 3, so that they can be better tightened.

[0026] The working principle of the utility model is as follows: when in use, the mounting plate 203 is directly mounted on one side of the rotating cylinder 1, and is conveniently connected by the fixing plate 6 and the fixing bolt 8. After the installation is completed, the tightening mechanism 2 is located on the outer side of the brake pad 3, which is convenient for tightening the brake pad 3. When the brake pad 3 rotates through the rotating cylinder 1, it directly enters the tightening mechanism 2 and directly contacts the slide plate 10. The slide plate 10 moves backward under the pressure of the brake pad 3, and applies the force to the curved rubber plate 210 through the second curved connecting plate 209. The curved rubber plate 210 performs preliminary buffering on the brake pad 3. Then the curved rubber plate 210 applies the force to the buffer spring 208 through the first curved connecting plate 211, and the buffer spring 208 buffers its force. As the rotating cylinder 1 drives the brake pad 3 to rotate, it can continue to rotate on the slide plate 10. Since the length of the slide plate 10 is consistent with the second curved connecting plate 209, During the sliding process of the brake pad 3, the brake pad 3 can be directly tightened by the reaction force through the overall fixed position of the clamping mechanism 2 and the buffering of the arc rubber plate 210 and the buffering force of the buffer spring 208, which effectively increases the clamping time and the clamping effect, and avoids the problem that the clamping block is rotated on the elastic power part by the rotational force of the brake pad 3 to tighten the brake pad 3 to a certain extent, resulting in a relatively low clamping time for the brake pad 3 and reduced clamping effect. When the model of the brake pad 3 is relatively large, the overall position of the clamping mechanism 2 can be adjusted, and the positioning bolt 207 can be directly opened. The stabilizing plate 5 is pulled outward by adjusting the handle 4. The stabilizing plate 5 drives the support plate 202 to move inside the adjusting groove 204. It can be adjusted to a suitable position according to the model size of the brake pad 3, and then the positioning bolt 207 is used to lower and fix it on the mounting plate 203 for use, avoiding the problem that the brake pad 3 cannot be tightened according to the model size of the brake pad 3.
