Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a grinding device for processing special-shaped brake pads. Background Technique

[0002] Brake pads are divided into drum brake pads and disc brake pads. Special-shaped brake pads mostly refer to disc brake pads. The working principle of braking mainly comes from friction. By using the friction between the brake pads and the brake disc and between the tires and the ground, the kinetic energy of the vehicle moving forward is converted into heat energy after friction to stop the vehicle. Brake pads are generally composed of a steel plate, an adhesive heat insulation layer and a friction block. Deviations will occur in the overall manufacturing, resulting in different specifications of brake pads. Therefore, further grinding treatment is required to make the specifications of brake pads unified.

[0003] When grinding brake pads, the brake pads will be clamped to the workbench and the position limit of the brake pads will be done well. Then, the grinding disc of the grinding machine will be contacted with the part of the brake pad that needs to be ground, and the grinding disc will be controlled to rotate and grind. Then, the ground brake pads will be taken out to complete the treatment. However, the rotation and grinding of the grinding disc and the brake pads flatten the uneven parts on the surface of the brake pads, but a large amount of heat will accumulate in this process. This heat accumulation reduces the grinding quality. Therefore, when using the grinding device, coolant needs to be sprayed on the grinding disc. If a large amount of coolant is not treated after use, it will cause waste of resources. Secondly, for the rotation and grinding of the grinding disc and the brake pads, some workers usually use a hand-held grinding machine and hold the brake pads with the other hand for grinding, which is not only dangerous, but also the brake pads cannot meet the requirements. Based on this, we designed a grinding device for processing special-shaped brake pads. Content of the Utility Model

[0004] The utility model provides a grinding device for processing special-shaped brake pads, which solves the above background problems.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A grinding device for processing special-shaped brake pads, including a grinding table, a first motor for controlling the movement of the grinding device, and a first cylinder located on top of the first motor. The top of the first cylinder is fixed with a connecting piece through a movable rod. A second cylinder is installed on the left side of the connecting piece. The left side of the second cylinder is fixed with a second motor through a movable rod. The output shaft of the second motor is connected with a grinding disc. A protection plate is fixed on the outer periphery of the second motor, and a splash-proof cover is connected to the outer periphery of the protection plate;

[0006] A recovery tank is fixed at the bottom of the grinding table. One side of the recovery tank is connected to a centrifugal pump. The input end of the centrifugal pump communicates with the inside of the recovery tank. The input end of the centrifugal pump is connected to a recovery pipe. One end of the recovery pipe is connected to a filter screen. The end of the pipeline of the recovery pipe is connected to a coolant storage tank. The top of the coolant storage tank is connected to an infusion pipe. The infusion pipe is connected to the coolant storage tank. Under the pumping of the centrifugal pump, the liquid inside the coolant storage tank can be pumped into the protection plate and then contact the grinding disc.

[0007] Optionally, a blower is installed at the center of the bottom of the grinding table. The blower consists of a support frame, a control motor and a fan blade. The control motor is installed in the middle of the support frame. The control motor is fixed by three support members, and the output shaft of the control motor is connected to the fan blade.

[0008] Optionally, a screening plate is arranged inside the recovery tank, and sliders slidably connected to the inner wall of the recovery tank are respectively fixed on both sides of the screening plate. At the same time, one side of the screening plate extends to the outside of the recovery tank and is fixed with a pull plate.

[0009] Optionally, a processing plate is connected to the middle of the grinding table. A guiding groove is formed in the middle of the processing plate. Clamping cylinders are fixed on both sides of the processing plate. One end of the clamping cylinder is fixedly connected to a clamping arm, and a rubber pad is inserted in the middle of the clamping arm.

[0010] Optionally, a plurality of sewage outlets are clamped on the surface of the grinding table, and a cleaning plate is installed inside the grinding table. The cleaning plate can slide in the gap between the grinding table and the processing plate. An auxiliary handle is installed on the top of the cleaning plate.

[0011] The utility model has the following beneficial effects:

[0012] 1. For the grinding device for processing special-shaped brake pads, the splash guard gathers the debris generated during the grinding of the grinding disc, and the groove of the grinding table recovers the debris into the recovery tank. Moreover, the coolant also plays a role in gathering the debris. In addition, the rotation of the blower causes a suction phenomenon on the surface of the grinding table, which can suck the debris into the recovery tank. After the processing is completed, the cleaning plate is used to clean the debris remaining on the surface of the grinding table. These treatments can better recycle the debris and do not affect the use of the grinding machine. At the same time, the clamping arm cooperates with the rubber pad to clamp and fix the adapted special-shaped brake pads, ensuring their stability during grinding and improving the grinding effect.

[0013] 2. The grinding device for processing the special-shaped brake pads conveys the coolant stored inside the coolant storage tank to the contact between the protection plate and the grinding disc inside the protection plate through the infusion pipe to cool it. And the coolant filters the debris contained through the screening plate inside the recovery tank to complete the preliminary treatment. Then, the centrifugal pump conveys the preliminarily treated coolant into the coolant storage tank. During this process, the filter screen will filter the fine debris inside the preliminarily treated coolant to ensure the recyclability of the coolant and reduce the waste of the coolant during the use of the grinding machine.
