Description

Technical Field

[0001] This utility model relates to the field of brake pad processing technology, specifically to an automatic brake pad outer arc grinding machine for detecting incoming materials. Background Technology

[0002] Automotive brake pads, also called brake linings, are friction materials fixed to the brake drum or brake disc that rotates with the wheel. The friction linings and friction blocks withstand external pressure, generating friction to slow the vehicle down. Based on brake type, they can be divided into brake pads for disc brakes, brake pads for drum brakes, and brake linings for large trucks. Drum brake pads, in particular, require grinding their outer arc during the manufacturing process.

[0003] Chinese Utility Model Announcement No. CN211193291U includes a device frame. The upper part of the device frame has a support plate, and the upper part of the support plate has a connecting frame. Inside the connecting frame is a mounting frame. One side of the mounting frame has a sliding mechanism, and the other side has a support rod. Inside the mounting frame is a servo motor, and below the servo motor is a connecting rod. Below the connecting rod is a grinding head. The grinding head and the connecting rod are fixed by bolts and nuts. Below the grinding head is a limiting plate, and inside the limiting plate is a clamp. Inside the device frame is a fixing frame, and inside the fixing frame is a cylinder. The upper part of the cylinder has a top column, which is embedded inside the support plate. By controlling the up-and-down movement of the brake pads within the clamp to perform grinding with the grinding head, grinding efficiency and product quality of the brake pads are improved.

[0004] The applicant discovered some shortcomings in the use of the patent: when the brake pads are placed in the fixture, the grinding head is located directly above the fixture, and the worker's fingers are directly below the grinding head. If the grinding head accidentally falls, it may come into contact with the fingers, posing a certain safety hazard.

[0005] Therefore, this utility model designs an automatic brake pad outer arc grinding machine for detecting incoming materials to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide an automatic brake pad outer arc grinding machine for detecting incoming materials, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic brake pad outer arc grinding machine for detecting incoming materials, comprising: a base, an L-shaped plate mounted on one side of the top of the base, an electric cylinder mounted on the top of the L-shaped plate, a mounting block connected to the output end of the electric cylinder, a grinding motor mounted on one side of the mounting block, a grinding rod connected to the output end of the grinding motor, a PLC controller provided on the L-shaped plate, an electric push rod mounted on the other side of the top of the base, a U-shaped plate connected to the output end of the electric push rod, a rotating shaft rotatably mounted between the two sides of the U-shaped plate, one side of the rotating shaft connected to the output end of a servo motor, a rotating block mounted on the outer wall of the rotating shaft, a support platform mounted on the top of the rotating block via a weighing module, a brake pad placed on the top of the support platform, and a clamping assembly provided on the support platform.

[0008] Preferably, the clamping assembly includes two mounting slots, in which an electric telescopic rod is installed. The output end of the electric telescopic rod is connected to a clamping block via a connecting block. The electric telescopic rod drives the connecting block to retract, bringing the two clamping blocks closer together, thereby clamping both sides of the brake pad. The height of the clamping blocks is slightly lower than the height of the brake pad.

[0009] Preferably, the clamping block is provided with a rubber anti-slip pad on the side near the brake pad, which can improve the friction between the clamping block and the brake pad.

[0010] Preferably, a dust collection hood is installed below the mounting block on the side near the grinding rod, and a dust collection pipe is connected to the other side of the dust collection hood. The dust collection pipe is connected to a vacuum cleaner so that debris can be collected during grinding.

[0011] Preferably, rollers are provided on both sides of the bottom of the U-shaped plate. The rollers are rotatably connected to the base. The movement of the U-shaped plate drives the rollers to roll, which can reduce the friction of the U-shaped plate.

[0012] Preferably, a rotating disk is installed at the bottom of the rotating block, and an arc-shaped groove is opened on the bottom inner wall of the rotating shaft to slide with the rotating disk. When the rotating block rotates, it drives the rotating disk to rotate in the arc-shaped groove, which can improve the stability of the rotating block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this invention, when placing the brake pads, the support platform is located below the grinding rod, which avoids the grinding rod accidentally falling and coming into contact with fingers, thus improving safety. After the brake pads are placed on the support platform, the weighing module senses the weight and confirms the arrival of the material. It then automatically transmits signals one by one at one-second intervals to the electric telescopic rod, electric push rod, electric cylinder, and servo motor. This first automatically fixes the brake pads, then automatically sends the brake pads directly below the grinding rod. The grinding rod then automatically falls down to contact the brake pads. Finally, the servo motor drives the brake pads to swing back and forth, and the grinding rod grinds the outer arc of the brake pads. This automatic process is more convenient.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3An embodiment of this utility model provides an automatic brake pad outer arc grinding machine for detecting incoming materials, comprising: a base 1, an L-shaped plate 2 mounted on one side of the top of the base 1, an electric cylinder 3 mounted on the top of the L-shaped plate 2, an output end of the electric cylinder 3 connected to a mounting block 4, a grinding motor 5 mounted on one side of the mounting block 4, a grinding rod 6 connected to the output end of the grinding motor 5, a PLC controller 7 mounted on the L-shaped plate 2, an electric push rod 8 mounted on the other side of the top of the base 1, a U-shaped plate 9 connected to the output end of the electric push rod 8, a rotating shaft 10 rotatably mounted between the two sides of the U-shaped plate 9, one side of the rotating shaft 10 connected to the output end of a servo motor 11, a rotating block 12 mounted on the outer wall of the rotating shaft 10, a support platform 14 mounted on the top of the rotating block 12 via a weighing module 13, a brake pad 15 placed on the top of the support platform 14, and a clamping assembly 16 mounted on the support platform 14.

[0018] Please see Figure 1-3 In this embodiment: the clamping assembly 16 includes two mounting slots 161, an electric telescopic rod 162 is installed in the mounting slot 161, and a clamping block 164 is installed at the output end of the electric telescopic rod 162 through a connecting block 163.

[0019] Please see Figure 1-3 In this embodiment: the clamping block 164 is provided with a rubber anti-slip pad on the side near the brake pad 15.

[0020] Please see Figure 1-3 In this embodiment: a dust suction hood 17 is installed on the lower side of the mounting block 4 near the grinding rod 6, and a dust suction pipe 18 is connected to the other side of the dust suction hood 17.

[0021] Please see Figure 1-3 In this embodiment: Rollers 19 are provided on both sides of the bottom of the U-shaped plate 9, and the rollers 19 are tactilely connected to the base 1.

[0022] Please see Figure 1-3 In this embodiment: a rotating disk 20 is installed at the bottom of the rotating block 12, and an arc-shaped groove 21 is provided on the bottom inner wall of the rotating shaft 10 to slide with the rotating disk 20.

[0023] Working principle: The brake pad 15 is placed on top of the support platform 14, the top of which is arc-shaped and fits against the inner arc of the brake pad 15. After the weighing module 13 senses the gravity, it transmits a signal to the electric telescopic rod 162. The electric telescopic rod 162 drives the connecting block 163 to retract, so that the clamping block 164 clamps and fixes the brake pad 15 on both sides. The weighing module 13 continues to transmit a signal to the U-shaped plate 9, which drives the rotating shaft 10 to move, moving the brake pad 15 directly below the grinding rod 6. Then, the weighing module 13 transmits a signal to the electric cylinder. 3. The electric cylinder 3 drives the grinding rod 6 to descend, and the grinding rod 6 contacts the outer arc of the brake pad 15. Finally, the weighing module 13 transmits the signal to the servo motor 11. The servo motor 11 drives the rotating shaft 10 to rotate forward and backward at a certain angle, so that the brake pad 15 rotates forward and backward. The grinding rod 6 can then grind the outer arc of the brake pad 15. By feeding material on one side of the grinding rod 6 and then automatically detecting the incoming material and automatically sending the brake pad 15 directly below the grinding rod 6, it is safer. The contents not described in detail in this description belong to the prior art known to those skilled in the art.
