Description

Technical Field

[0001] This utility model relates to the technical field of brake pad processing equipment, specifically to a high-efficiency brake grinding device. Background Technology

[0002] Brake pads, also known as brake discs, are the most critical safety component in a car's braking system. The effectiveness of braking depends entirely on the brake pads; therefore, good brake pads are considered the guardians of both people and vehicles. When brake pads wear out, they need to be replaced. During replacement, the edges and corners often need to be ground to achieve noise matching between the new brake pad and the brake disc, reducing friction noise. However, currently, grinding the edges and corners of brake pads is generally done manually, which is inefficient and prone to accidents. While patent number CN209453297U, entitled "A High-Efficiency Grinding Device for Brake Pad Processing," utilizes two processing components to grind brake pads, significantly improving efficiency, it still requires manual feeding and cannot grind the edges and corners of the brake pads. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a high-efficiency brake polishing device.

[0004] According to the technical solution provided in the embodiments of this application, a high-efficiency brake grinding device includes a bracket, a support plate fixedly mounted on the bracket, a brake pad placement plate on the upper end surface of the support plate, and the brake pad placement plate rotating relative to the support plate on a horizontal plane by a rotary motor fixed on the support plate; a feeding frame, an inner arc grinding device, and an outer arc grinding device are fixedly mounted on the bracket above the brake pad placement plate, the feeding frame, the inner arc grinding device, and the outer arc grinding device are respectively located on the side end of the brake pad placement plate, the brake pad placement plate is provided with a plurality of brake pad placement holes, the brake pads in the feeding frame fall into the brake pad placement holes due to their own weight, are supported by the support plate, and as the brake pad placement plate continues to rotate, the brake pads in the brake pad placement holes are successively ground by the inner arc grinding device and the outer arc grinding device to grind the inner and outer corners of the brake pads.

[0005] Furthermore, the support plate is provided with brake pad exit holes, which can be located on the same vertical plane as one of the brake pad placement holes, so that the brake pad can fall from the brake pad placement hole to the brake pad exit hole.

[0006] Furthermore, the feeding frame is a vertically placed cuboid shape with brake pad feeding holes, and multiple brake pads are placed there.

[0007] Furthermore, the inner arc grinding device includes a U-shaped bracket, an angle adjustment cylinder, and a grinding device. The middle part of the grinding device is hinged to the U-shaped bracket via a pin. One end of the grinding device is hinged to the piston rod of the angle adjustment cylinder, and the other end of the angle adjustment cylinder is hinged to the U-shaped bracket. The U-shaped bracket is fixedly connected to the bracket via a micro-adjustment device, which consists of several adjustment devices. The compression spring on the adjustment device is movably sleeved on the telescopic rod to realize the adjustment of the tilt angle and distance of the inner arc grinding device.

[0008] Furthermore, the grinding device includes a grinding wheel and a transmission block. The motor shaft of the transmission motor inside the transmission block is fixedly connected to the grinding wheel, and U-shaped brackets are hinged to both ends of the transmission block to achieve grinding using the grinding wheel.

[0009] Furthermore, the outer arc grinding device has the same structure as the inner arc grinding device. The distance between the outer arc grinding device and the support on the outer arc grinding device is smaller than the distance between the grinding device and the support on the inner arc grinding device, thereby enabling multi-part grinding of the brake pads and improving work efficiency.

[0010] In summary, the beneficial effects of this application are as follows: The device of this application achieves automatic feeding and unloading by the self-weight of the brake pads, which can greatly improve work efficiency; The device of this application uses a micro-adjustment device to finely adjust the contact between the inner and outer arc end faces of the brake pads placed in the brake pad placement holes and the grinding wheel, thereby achieving edge grinding of the inner and outer arc end faces of the brake pads, realizing automatic grinding of the brake pads, which greatly improves work efficiency and reduces the risk of manual operation.

Detailed Implementation

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A high-efficiency brake grinding device, such as Figure 1 As shown, the bracket 1 includes a vertically arranged support rod and an arc-shaped connector for fixing the support plate 2. The three brackets 1 suspend the support plate 2 in the air. A brake pad placement plate 3 is set above the support plate 2. The brake pad placement plate 3 has several brake pad placement holes 31 arranged in a circle. A feeding frame 4, an inner arc grinding device 5 and an outer arc grinding device 6 are respectively fixed on the three brackets 1. The feeding frame 4, the inner arc grinding device 5 and the outer arc grinding device 6 are respectively located at the side ends above the brake pad placement plate 3.

[0021] like Figure 2 As shown, the lower end face of the brake pad placement disc 3 is slidably connected to the support disc 2 via an annular slide rail, and a rotary motor is provided inside the support disc 2. The motor shaft of the rotary motor passes through the support disc 2 and is fixedly connected to the middle part of the brake pad placement disc 3, so that the brake pad placement disc 3 can rotate relative to the support disc 2 on the horizontal plane. The support disc 2 is provided with a brake pad through-hole 21, so that when the brake pad placement disc 3 rotates, it can be located on the same vertical plane as the brake pad placement hole 31.

[0022] like Figure 3 As shown, the outer arc grinding device 6 is fixed on the bracket 1 by the micro-adjustment device 7;

[0023] like Figure 4As shown, the inner arc grinding device 5 is fixed on the bracket 1 by the micro-adjustment device 7, and the grinding device 53, which consists of the grinding wheel 531 and the transmission block 532, is hinged to the U-shaped bracket 51 by the pin. The pin on the transmission block 532 is hinged to the U-shaped bracket 51. The rear end face of the transmission block 532 is hinged to the piston rod of the tilt angle adjustment cylinder 52. The rear end face of the tilt angle adjustment cylinder 52 is hinged to the U-shaped bracket 51. The rear end face of the U-shaped bracket 51 is fixedly connected to the bracket 1 by the micro-adjustment device 7.

[0024] like Figure 5 As shown, the micro-adjustment device 7 consists of multiple adjustment devices, and the compression spring 71 on the adjustment device is movably sleeved on the telescopic rod 72, so that the distance between the inner arc grinding device 5 and the bracket 1 can be adjusted.

[0025] Before use, first stack the brake pads (mainly disc brake pads) in the brake pad feeding hole 41 of the feeding frame 4, and then start the rotating motor in the support plate 2 to make the brake pad placement plate 3 rotate. At this time, the brake pads in the feeding frame 4 will fall into the brake pad placement hole 31 due to their own weight. The bottom of the brake pads is supported by the upper surface of the support plate 2, so that the upper surface of the brake pads is exposed above the upper surface of the brake pad placement hole 31.

[0026] When the brake pad placed in the brake pad placement hole 31 is rotated to the inner arc grinding device 5, the tilt adjustment cylinder 52 is activated, so that the grinding device 53 is tilted relative to the U-shaped bracket 51. At this time, the grinding wheel 531 on the grinding device 53 has a certain tilt angle. Since the inner arc of the brake pad is not a circular arc, when the grinding wheel 531 contacts the inner arc of the brake pad, it will shorten and lengthen due to the micro-adjustment device 7 to ensure that the grinding wheel 531 contacts the inner arc corner of the brake pad. Under the transmission of the transmission motor in the transmission block 532, the grinding wheel 531 can grind the inner arc corner of the brake pad. Similarly, when the brake pad is rotated to the outer arc grinding device 6, the outer arc corner of the brake pad is ground.

[0027] The adjustment principle of the tilt adjustment cylinder 52 is as follows: when the piston rod of the tilt adjustment cylinder 52 extends, the distance between the grinding device 53 and the cylinder body of the tilt adjustment cylinder 52 extends. Since the position of the grinding device 53 remains unchanged, the extension of the piston rod of the tilt adjustment cylinder 52 can only be achieved when the tilt angle of the grinding device 53 changes. For example, if the initial position is: the tilt adjustment cylinder 52 is placed horizontally and the grinding device 53 is placed horizontally, when the piston rod extends, the tilt angle of the grinding device 53 changes, then the connection point between the piston rod and the grinding device 53 will move up or down, and the angle of the tilt adjustment cylinder 52 will also change. Although the displacement of the tilt adjustment cylinder 52 does not change, the distance between its cylinder body and the connection point between the piston rod and the grinding device 53 will extend.

[0028] The grinding principle of the inner arc grinding device 5 and the outer arc grinding device 6 on the edge and corner of the brake pad is as follows: When the grinding device 53 and the outer arc grinding device 63 are tilted, they are in contact with the edge and corner of the brake pad. Because the inner arc end face and the outer arc end face are not strictly circular arc structures, there will be a certain distance difference. This distance difference can be adjusted by the compression spring 71 on the micro-adjustment device 7, and the telescopic rod 72 can ensure the stability of the connection between the inner arc grinding device 5 and the outer arc grinding device 6.

[0029] After the brake pads are polished, the brake pad placement hole 31 on the brake pad placement disc 3 continues to rotate with the brake pads until it rotates to the point directly above the brake pads exiting the hole 21. At that point, the polished brake pads will fall out of the brake pads exiting the hole 21 due to their own weight.

[0030] Each time the brake pad placement hole 31 on the brake pad placement disc 3 rotates to the bottom of the feeding frame 4, the new brake pad can be transported to the inner arc grinding device 5 and the outer arc grinding device 6 for grinding.

[0031] In this design, the thickness of the brake pad mounting disc 3 should be less than the thickness of the brake pad.

[0032] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and other solutions employed. Furthermore, the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
