Description

Technical Field

[0001] This utility model relates to the technical field of brake pad production and processing equipment, and in particular to a brake pad edge grinding device. Background Technology

[0002] In the automotive brake pad manufacturing industry, the edge grinding process is a critical step that directly affects the braking performance and safety of the product. Existing technologies, such as traditional brake pad edge grinding equipment, have significant technical defects: First, the equipment lacks compatibility. Most devices use fixed-specification clamping structures, and when faced with brake pad width differences (50-200mm) between different vehicle models (such as sedans, SUVs, and heavy trucks), the machine must be stopped to change the mechanical clamps, with each adjustment taking more than 30 minutes, severely impacting production line efficiency. Second, the positioning system has technical bottlenecks; the rigid limiting structure cannot adapt to the curved chamfer design of the brake pad edges (such as R150-R200mm curvature), making grinding difficult. During the process, the workpiece offset often exceeds 0.5mm, resulting in an edge roughness Ra value greater than 3.2μm, which cannot meet the precision requirements of high-end ceramic brake pads (Ra≤1.6μm); thirdly, the automated conveying system has design flaws, requiring manual pushing of workpieces in the horizontal feed chute, and the discharge port often jams due to dust accumulation, resulting in an average of 2-3 shutdowns per hour for cleaning, with manual intervention costs accounting for 18% of the total production cost; fourthly, the dust treatment technology is outdated, and the open grinding environment leads to excessive metal dust concentration (measured at 35mg / m³). 3 (Exceeding the GBZ 2.1-2019 standard by 3.5 times), which not only endangers the health of operators, but also increases the failure rate of equipment transmission components by 40% due to dust accumulation.

[0003] The aforementioned technical problems result in an overall yield rate of only 82%-88% for existing devices, which is insufficient to meet the high-precision processing requirements of automotive brake pads (with an annual demand growth of 25%). Therefore, this utility model proposes a brake pad edge grinding device to solve the above problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a brake pad grinding device that can adapt well to brake pads of different sizes, stably feed, dynamically position, precisely grind and stably discharge, while reducing workload and minimizing manual intervention, thereby effectively improving the efficiency of brake pad grinding.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a brake pad grinding device, comprising a cylindrical box, a support frame, a support roller, a drive motor, a limiting component, two sliding frames, multiple limiting baffles, an adjustment component one, two mounting plates, two motors three, and an adjustment component two;

[0007] The bottom inner wall of the cylindrical box is provided with a ash discharge port, a feed port and an discharge port.

[0039] Reference Figure 1-7 A brake pad edge grinding device includes a cylindrical box 1, a support frame 11, a support roller 2, a drive motor 21, two sliding frames 32, multiple limit baffles 3, two mounting plates 41, and two motors 5.

[0040] The bottom inner wall of the cylindrical box 1 is provided with a ash discharge port 101, a feed port, and a discharge port. The feed port and discharge port are located on the front and rear sides of the cylindrical box 1, respectively, and the ash discharge port 101 is located at the bottom of the cylindrical shell. A feed trough 102 and a discharge trough 103 are fixedly installed in the feed port and discharge port, respectively. In order to allow the brake pads to slide towards the support roller 2 after being placed in the feed trough 102, and to allow the brake pads to be discharged from the discharge trough 103 after grinding as the support roller 2 rotates, the feed trough 102 and the discharge trough 103 are inclined to allow the brake pads to be discharged from the discharge trough 103 after grinding. The discharge troughs 103 are all inclined, and the feed troughs 102 and discharge troughs 103 are parallel to each other. In addition, in order to reduce the resistance when the brake pads slide, and to stably deliver the brake pads to the support rollers 2, and to ensure that the polished brake pads are stably discharged from the discharge troughs 103 into the cylindrical box 1, the inner walls of the feed troughs 102 and the inner walls of the discharge troughs 103 are both smooth.

[0041] The drive motor 21 is fixedly installed on one side of the cylindrical box 1. The support roller 2 is set inside the cylindrical box 1 and is axially fixedly connected to the output shaft of the drive motor 21. In order to accurately control the rotation angle of the support roller 2 as needed and to keep it in a relatively stable state after adjustment, so as to facilitate the grinding wheel 51 to perform grinding operation, the drive motor 21 is a servo motor. Multiple limit strips 201 arranged in parallel to each other are fixedly installed on the outside of the support roller 2, which can control a single brake pad to follow the movement of the support roller 2 as the support roller 2 rotates.

[0042] The support frame 11 is fixedly installed on the cylindrical box 1. Multiple limiting baffles 3 are set inside the cylindrical box 1. Two sliding frames 32 are slidably installed on the inner walls of both sides of the cylindrical box 1. Each of the two sliding frames 32 is fixedly installed with a sliding rod 31 that is slidably connected to the cylindrical box 1. Multiple sliding rods 31 are fixedly connected to the corresponding limiting baffles 3. In order to cooperate with the support roller 2 and the limiting strip 201 to stably limit the brake pads and thus ensure the stability of the brake pads during the grinding process, the limiting baffles 3 are L-shaped and the inner sidewalls of the limiting baffles 3 are curved. A motor 34 is fixedly installed on the support frame 11. A bidirectional screw rod that is threadedly connected to the two sliding frames 32 is rotatably installed on the support frame 11. One end of the bidirectional screw rod is axially fixedly connected to the output shaft of the motor 34. The distance between the two limiting baffles 3 on both sides can be controlled by the two sliding frames 32, so as to adapt well to the limiting of brake pads of different widths.

[0043] Two fixed brackets 4 are fixedly installed on both sides of the cylindrical box 1, and two mounting plates 41 are slidably installed on the corresponding fixed brackets 4. Two motors 5 are fixedly installed on the side of the two mounting plates 41 that are close to each other.

One of the fixed brackets 4 is fixedly installed with a motor 42. The output shaft of the motor 42 is axially fixedly connected to one end of the two-way lead screw 43. The distance between the two grinding wheels 51 can be controlled as needed, so as to adapt well to the grinding of brake pads of different widths.

[0044] Specifically, in order to ensure that the mounting plate 41 maintains stable sliding, a rectangular opening is provided on the fixing frame 4, and two guide rods 411 arranged in parallel to each other are fixedly installed in the rectangular opening. The mounting plate 41 is slidably connected to the two corresponding guide rods 411.

[0045] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0046] Working principle:

[0047] First, turn on the power and place the brake pads to be polished into the feed trough 102. Since the feed trough 102 is inclined, the brake pads slide to the position of the support roller 2. At the same time, the controller controls the drive motor 21 to drive the support roller 2 to rotate. Under the action of the limit bar 201, the brake pads are guided to the designated position. At this time, the motor 34 drives the double-acting screw 33 to rotate, so that the two sliding frames 32 move along the cylindrical box 1. In this way, with the cooperation of the sliding rod 31, the distance between the limit baffles 3 on both sides is adjusted to ensure that the brake pads are firmly clamped and in the center position. At the same time, the motor 42 drives the double-acting screw 43 to rotate, controlling the polishing wheels 51 on the two mounting plates 41 to move closer or further apart to adapt to the specific width requirements of the brake pads.

[0048] During the grinding process, the servo motor precisely controls the rotation angle of the support roller 2 to ensure that each brake pad can be stably adjusted to the grinding position and that the brake pad can make uniform contact with the grinding wheel 51. The curved surface design of the limit baffle 3 works together with the support roller 2 and the limit strip 201 to effectively prevent the brake pad from shifting during the processing. After the grinding is completed, the support roller 2 continues to rotate and automatically discharges the brake pad when it moves to the discharge chute 103 position by using its tilt setting.

[0049] Throughout the entire operation, the dust discharge port 101 continuously plays a role in timely discharging the dust generated during the edge grinding process. The smooth surface treatment of the feed trough 102 and the discharge trough 103 significantly reduces the friction when the brake pads slide, enabling them to smoothly complete the feeding and discharging process. This series of designs not only improves the edge grinding efficiency but also greatly reduces manual intervention, reflecting the intelligent and automated characteristics of the device.

[0050] The above provides a detailed description of the brake pad grinding device provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
