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. Background Technology

[0002] With economic and industrial development and the increase in the number of cars, the demand for brake pads is also increasing. In the process of processing and producing automotive brake pads, it is necessary to grind the outer arc of the brake pads, which requires the use of a grinding machine for grinding and polishing.

[0003] Chinese Utility Model Announcement No. CN219403691U includes a base, a limiting shell fixedly connected to the top of the base, a feeding box fixedly connected to one side of the limiting shell, an automatic brake pad feeding assembly mounted on the feeding box, two support plates fixedly connected to the other side of the limiting shell, a drive motor fixedly connected to the top of the base, a grinding wheel fixedly connected to the output shaft of the drive motor, a brake pad driving assembly disposed between the base and the limiting shell, and a conveying assembly disposed between the two support plates. This utility model has a reasonable structural design, achieving automatic feeding and discharging of brake pads, resulting in a higher degree of automation and significantly improved grinding efficiency. Furthermore, the rotation of the grinding wheel and the rotary table allows for grinding of the entire outer arc of the brake pad.

[0004] The applicant discovered some shortcomings in the use of the patent: the patent uses an electromagnet to attract brake pads, but some brake pads are made of materials such as asbestos and ceramics, which the electromagnet cannot attract, which is a limitation. In addition, the method of pushing the material with an arc-shaped pusher plate causes the brake pads to slide in the feed box, resulting in some wear on the bottom of the brake pads.

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

[0006] The purpose of this invention is to provide an automatic discharge brake pad external arc grinding machine 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 discharge brake pad external arc grinding machine, comprising: a worktable, an inclined plate mounted on one top end of the worktable, an electric cylinder mounted on the inclined plate, the output end of the electric cylinder connected to a grinding machine, a hollow shaft rotatably mounted at the top center of the worktable via a bearing, an air box connected to the top of the hollow shaft, and an arc-shaped box connected to the top of the air box via bent pipes around its perimeter, the arc-shaped box having several negative pressure holes, a U-shaped frame mounted at the bottom of the worktable, and a negative pressure machine mounted on the inner wall of the bottom of the U-shaped frame. The negative pressure machine and the bottom of the hollow shaft are connected by a rotary joint. Vertical frames are installed on both sides of one end of the top of the workbench. A lead screw is rotatably installed inside the vertical frame. A sliding plate is slidably installed on the outer wall of the lead screw through a thread. A rotating shaft is rotatably installed at one end of the sliding plate. A rotating plate is installed at one end of the rotating shaft. An electric push rod is installed at the bottom end of the rotating plate. An arc-shaped air box is connected to the output end of the electric push rod. Several suction holes are provided at the bottom of the arc-shaped air box. An air pump connected to the arc-shaped air box is installed on the top of the rotating plate. The sliding plate is slidably connected to the inner wall of the vertical frame.

[0008] Preferably, a worm gear is installed below the outer side wall of the hollow shaft, and a worm gear meshing with the worm gear is rotatably installed between the two sides of the U-shaped frame. The worm gear drives the worm gear to rotate, and the worm gear can make the hollow shaft rotate.

[0009] Preferably, connecting rods are installed around the bottom of the air box, and rollers that are tactilely connected to the worktable are installed at the bottom of the connecting rods. When the air box rotates, the rollers roll on the worktable, reducing the friction of the air box rotation.

[0010] Preferably, the bend is equipped with a solenoid valve, and the bottom of the air box is equipped with a battery linearly connected to the solenoid valve. The opening and closing of the bend can be controlled independently through the solenoid valve, and the battery supplies power to the solenoid valve.

[0011] Preferably, the air pump and the arc-shaped air box are connected by a corrugated pipe, which is telescopic, facilitating the movement of the arc-shaped air box by the electric push rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses an air box to supply air, which creates negative pressure in the negative pressure holes on the arc-shaped box to adsorb and fix the brake pads. The negative pressure machine uses high power and has better adsorption capacity. It can adsorb and fix the brake pads regardless of whether they are made of metal or non-metal, making it more practical. 2. This utility model uses an arc-shaped air box to descend and adsorb the brake pads through the adsorption holes. Then, the rotating shaft drives the rotating plate to rotate 80 degrees, and the electric push rod pushes the brake pads to contact the arc-shaped box, so that the negative pressure holes can adsorb the brake pads. Compared with the sliding method of the brake pads, this feeding method reduces the wear of the brake pads. Attached Figure Description

A lead screw 16 has a sliding plate 17 threadedly mounted on its outer wall. A rotating shaft 18 is rotatably mounted on one end of the sliding plate 17. A rotating plate 19 is mounted on one end of the rotating shaft 18. An electric push rod 20 is mounted on the bottom end of the rotating plate 19. An arc-shaped air box 21 is connected to the output end of the electric push rod 20. Several suction holes 22 are provided at the bottom of the arc-shaped air box 21. An air pump 23 connected to the arc-shaped air box 21 is mounted on the top of the rotating plate 19. The grinding machine includes a U-shaped plate. A grinding roller is rotatably mounted between the upper and lower ends of the U-shaped plate. The top of the grinding roller is connected to the output end of the grinding motor. The top of the lead screw is connected to the output end of the drive motor. A groove is provided on the sliding plate. A flipping motor is installed in the groove. The output end of the flipping motor is connected to one end of the rotating shaft.

[0017] Please see Figure 2 In this embodiment: a worm gear 13 is installed below the outer side wall of the hollow shaft 5, and a worm 14 that meshes with the worm gear 13 is rotatably installed between the two sides of the U-shaped frame 10, with one side of the worm connected to the output end of the servo motor.

[0018] Please see Figure 1 In this embodiment: connecting rods are installed around the bottom of the air box 6, and rollers that are rotatably connected to the worktable 1 are installed at the bottom of the connecting rods.

[0019] Please see Figure 1 In this embodiment: a solenoid valve is provided on the bend 7, and a storage battery that is linearly connected to the solenoid valve is provided at the bottom of the air box 6.

[0020] Please see Figure 3 In this embodiment: the air pump 23 and the arc-shaped air box 21 are connected by a corrugated pipe.

[0021] Working principle: The brake pads to be ground are neatly stacked in the placement area. The lead screw 16 on one side of the placement area rotates, causing the slide plate 17 to descend, which in turn lowers the arc-shaped air box 21. The vacuum pump 23 is activated, causing the suction hole 22 to adhere to the top of the brake pad. Then, the rotating shaft 18 drives the rotating plate 19 to rotate 90 degrees, so that the brake pad faces the arc-shaped box 8. Then, the electric push rod 20 drives the arc-shaped air box 21 to extend, so that the brake pad contacts the arc-shaped box 8. The negative pressure hole 9 adheres to the brake pad, and the suction hole 22 releases the brake pad. The feeding process is complete. The air box 6 rotates counterclockwise. During the rotation, the brake pads come into contact with the grinder 4, which grinds the outer arc of the arc box 8. When the ground brake pads are rotated to the arc air box 21 on the side away from the placement area, the arc air box 21 comes into contact with the brake pads. The suction hole 22 adsorbs the brake pads, and the negative pressure hole 9 cancels the adsorption of the brake pads. The ground brake pads can then be removed and automatically discharged. The contents not described in detail in this instruction are existing technologies known to those skilled in the art.
