Description

Technical Field

[0001] This utility model relates to the field of automotive brakes, specifically to an automotive brake end face grinding device. Background Technology

[0002] The car brake is an important component used to control the speed and stop of a car. It typically includes components such as brake discs, brake pads, brake fluid, and brake cylinders. When the driver presses the brake pedal, the brake fluid transmits pressure to the brake cylinder, causing the brake pads to rub against the brake disc and generate resistance, thereby slowing down or stopping the car.

[0003] Today, automotive brakes are broadly classified into disc brakes and drum brakes. Disc brakes consist of a brake disc, a brake caliper, and brake pads. The brake disc is typically mounted on the wheel. When the brake pedal is depressed, the brake caliper clamps the brake disc, causing the wheel to slow down or stop rotating. The brake pads are the friction material inside the brake caliper. They generate friction with the brake disc to slow the vehicle. Therefore, to ensure good braking friction and safety, the end faces of the brakes need to be ground and polished after production to make the surface smooth and flat. However, during the brake grinding process, different levels of pitting and burrs on the brake surface require different grinding feed rates. Often, the grinding surface is insufficient, resulting in burrs that cannot be removed, or the grinding feed rate is too high, causing the brake to be thinned. This makes the end face grinding of the brake difficult to control, increasing the defect rate. Summary of the Invention

[0004] (1) Technical problems solved

[0005] The technical problem to be solved by this utility model is that in the brake grinding process, different grinding feed forces are required for different degrees of pitting and burrs on the brake surface. Often, the grinding degree of the grinding surface is insufficient, resulting in the inability to remove burrs, or the grinding feed is too high, that is, the grinding degree is too high, resulting in the brake being thinned. This makes it difficult to control the grinding of the brake end face, resulting in an increase in the defect rate.

[0006] (II) Technical Solution

[0007] To solve the above problems, this utility model provides the following technical solution:

[0008] A grinding device for the end face of an automotive brake includes a base, a grinding machine body at one end of the base, a drive shaft at one end of the grinding machine body, a grinding wheel at one end of the drive shaft, a sliding groove at the other end of the base, a clamping assembly on the sliding groove, the clamping assembly including a slider, a fixed base and a gripper, a back plate on one side of the fixed base, a hydraulic cylinder assembly on one side of the back plate, a hydraulic rod of the hydraulic cylinder assembly being fixedly connected to the back plate, and the slider being located at the bottom of the back plate.

[0009] Furthermore, the base is hollow inside, and debris holes are opened on the base.

[0010] Furthermore, the grinding wheel is positioned above the chip hole.

[0011] Furthermore, the slider is engaged in the slide groove, and the clamping assembly is connected to the slide groove via the slider.

[0012] Furthermore, a support platform is provided below the hydraulic cylinder assembly.

[0013] (III) Beneficial Effects

[0014] The beneficial effects of this utility model are:

[0015] The clamping assembly is driven by a hydraulic cylinder assembly. When the end face of the brake needs to be polished, it is fixed by the jaws and then the hydraulic cylinder is manually controlled to slowly advance for polishing. The pushing process is from shallow to deep to prevent over-polishing, which could damage the end face of the brake and make it too thin. The cooperation of the slide and the slider allows for multiple stops to observe during the polishing process. When there are many or deep burrs and concave surfaces, the pushing amount can be increased to match the polishing amount, resulting in a better polishing effect, increased yield, and reduced rework.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Please see Figure 1-2 The invention relates to a grinding device for the end face of an automotive brake, comprising a base 1, a grinding machine body 2 at one end of the base 1, a drive shaft 2a at one end of the grinding machine body 2, a grinding wheel 3 at one end of the drive shaft 2a, a slide groove 4 at the other end of the base 1, a clamping assembly 5 on the slide groove 4, the clamping assembly 5 comprising a slider 5a, a fixed base 5b and a gripper 5c, a back plate 5d on one side of the fixed base 5b, a hydraulic cylinder assembly 6 on one side of the back plate 5d, the hydraulic rod of the hydraulic cylinder assembly 6 being fixedly connected to the back plate 5d, and the slider 5a being located at the bottom of the back plate 5d.

[0022] The base 1 is hollow inside and has a chip hole 1a. The chips generated during end face grinding will fall into the base 1 through the chip hole 1a. The hollow inside the base 1 is a chip collection point. The chips are collected and then recycled. The grinding wheel 3 is located above the chip hole 1a so that the chips generated during grinding can fall into the chip hole 1a and be collected in the base 1.

[0023] The slider 5a is mounted on the slide groove 4. The clamping assembly 5 is connected to the slide groove 4 via the slider 5a. The slider 5a is limited by the slide groove 4 and can reciprocate on the slide groove 4. It is driven by the hydraulic cylinder assembly 6 to advance and retract on the slide groove 4. During grinding, the brakes are classified and ground in groups according to the observation of the brake end face by the on-site workers. The hydraulic cylinder assembly 6 is controlled to advance to different degrees, so that the clamping assembly 5 clamps the brake and moves it closer to the grinding wheel 3 and makes contact. During the grinding process, the hydraulic cylinder assembly 6 slowly presses forward. To increase the propulsion volume, whether to use the hydraulic cylinder assembly 6 for forward pressing during the grinding process depends on the degree of burrs and pits on the brake end face, including the distance of the forward pressing feed. If there are few and short burrs on the surface, grinding can be completed by pushing the brake to contact the grinding wheel 3. If there are many burrs and pits on the surface, the hydraulic cylinder assembly 6 needs to be driven forward again after burr grinding for further grinding. The grinding process requires manual observation by on-site personnel. The condition of the brake end face can be observed in real time by retracting the hydraulic cylinder assembly 6 to bring back the clamping assembly 5.

[0024] A support platform is provided below the hydraulic cylinder assembly 6 to support the hydraulic cylinder assembly 6.

[0025] The specific working principle is as follows: the brakes to be polished are classified, and then the brakes are placed on the clamping assembly 5 and clamped by the jaws 5c. Then, the hydraulic cylinder assembly 6 is activated to push the clamping assembly 5 forward along the slide groove 4 until the brake contacts the polishing wheel 3 and stops. Then, the polishing machine body 2 drives the polishing wheel 3 to polish the end face of the brake. The debris generated during the process falls into the base 1 for collection. The condition of the brake end face is observed in real time during the polishing process. If burrs or pits still exist on the surface, the hydraulic cylinder assembly 6 is further driven forward to apply additional polishing force.
