Description

Technical Field

[0001] This utility model relates to the field of brake pad cutting technology, and in particular to a positioning structure for cutting disc brake pads. Background Technology

[0002] Brake pads need to be cut to the size required by the braking system of a specific vehicle model during the production process. Different vehicle models have different brake disc sizes, shapes, and brake caliper installation spaces. Cutting allows for precise adjustment of the brake pad size to ensure that it can be perfectly installed in the corresponding braking system.

[0003] Currently, during the brake pad cutting process, after one brake pad is cut, the operator needs to release its limiting mechanism, remove the brake pad, place the next set of brake pads to be cut, and then limit it before cutting. However, this process involves a long interval, resulting in prolonged equipment downtime and reduced cutting efficiency. Furthermore, when cutting brake pads, only lateral limiting is usually applied, and longitudinal displacement of the brake pad occurs during the cutting process, which reduces cutting accuracy. After searching, it was found that the technical solution provided by the utility model application with application number CN202020130799.7 also has the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a positioning structure for cutting disc brake pads. During the cutting of the first set of disc brake pads, another set of limiting components unloads and feeds the disc brake pads. The operator does not need to stop the machine to unload and load the disc brake pads after the first set of disc brake pads is cut, which reduces the downtime of the equipment, improves the continuity of production cutting, and thus improves the cutting efficiency of disc brake pads.

[0005] To achieve the above objectives, this utility model also provides a positioning structure for cutting disc brake pads, comprising: an operating table and a limiting component; a fixed box is fixedly connected to the lower surface of the operating table; a first cylinder is fixedly connected to the left surface of the fixed box; a moving plate is fixedly connected to the output end of the first cylinder; a rack is fixedly connected to the front surface of the moving plate; a bearing is fixedly connected to the bottom inner wall of the fixed box; a first rotating shaft is fixedly connected to the inner surface of the bearing; a gear is fixedly connected to the side surface of the first rotating shaft; a rotating disk is fixedly connected to the upper surface of the first rotating shaft; the limiting component includes a fixed seat, a second cylinder, a limiting plate, a fixed plate, a top plate, an electric telescopic rod, and a lower pressure plate; the upper surface of the rotating disk is fixedly connected to the fixed seat; a placement groove is provided inside the fixed seat; the rear surface of the fixed seat is fixedly connected to the second cylinder; and the output end of the second cylinder is fixedly connected to the limiting plate.

[0006] According to the positioning structure for cutting disc brake pads, the side surface of the gear is meshed with the rack, and the side surface of the gear is rotatably connected to the operating table.

After cutting, the first cylinder is started to move the moving plate back to its initial position, and the positions of the two sets of fixed seats on the rotating disk are switched. This process saves the time for operators to stop and pick up and place disc brake pads, reduces equipment downtime, and thus improves the processing efficiency of disc brake pads.

[0014] 1. By setting up a fixed box, a first cylinder, a moving plate, a rack, a bearing, a first rotating shaft, a gear, a rotating disk, and a limiting assembly, during the cutting of the first set of disc brake pads, another set of limiting assemblies unloads and feeds the disc brake pads. Operators do not need to stop the machine to unload and load the disc brake pads after the first set of disc brake pads is cut, which reduces the downtime of the equipment, improves the continuity of production cutting, and thus improves the cutting efficiency of disc brake pads.

[0015] 2. By setting a fixed seat, placement slot, second cylinder, limit plate, fixed plate, top plate, electric telescopic rod and lower pressure plate, the brake pad can be limited laterally and longitudinally at the same time, reducing the positional displacement of the disc brake pad during the cutting process, thereby improving the cutting accuracy.

[0026] Reference Figure 1-5 This utility model discloses a positioning structure for cutting disc brake pads, comprising: an operating table 1 and a limiting component 25. A fixed box 2 is fixedly connected to the lower surface of the operating table 1. A first cylinder 3 is fixedly connected to the left surface of the fixed box 2. A moving plate 4 is fixedly connected to the output end of the first cylinder 3. A rack 5 is fixedly connected to the front surface of the moving plate 4. A bearing 6 is fixedly connected to the bottom inner wall of the fixed box 2. A first rotating shaft 7 is fixedly connected to the inner surface of the bearing 6. A gear 8 is fixedly connected to the side surface of the first rotating shaft 7. The side surface of the gear 8 meshes with the rack 5 and is rotatably connected to the operating table 1. A rotating disk 9 is fixedly connected to the upper surface of the first rotating shaft 7. By activating the first cylinder 3, the moving plate 4 and the rack 5 are moved... The rack 5 moves, driving the first rotating shaft 7, gear 8, and rotating disk 9 to rotate. This allows the fixed seat 10 on one side of the rotating disk 9 to move the cutting head 23 to the other side for cutting. After cutting, the first cylinder 3 is activated, driving the moving plate 4 to move back to the initial position. The positions of the fixed seat 10 on the rotating disk 9 are interchanged. The operator can feed and unload another set of disc brake pads while one set of disc brake pads is being cut, making the cutting of disc brake pads more continuous and thus improving the cutting efficiency of disc brake pads. A baffle 24 is fixedly connected to the upper surface of the rotating disk 9. The baffle 24 is designed to prevent the waste generated by the disc brake pads being cut from affecting the operator during the feeding and unloading of a set of disc brake pads.

[0027] The limiting assembly 25 includes a fixed base 10, a second cylinder 12, a limiting plate 13, a fixed plate 14, a top plate 15, an electric telescopic rod 16, and a lower pressure plate 17. The upper surface of the rotating disk 9 is fixedly connected to the fixed base 10. There are two fixed bases 10, which are distributed front and back. The fixed base 10 has a placement groove 11 inside. The rear surface of the fixed base 10 is fixedly connected to the second cylinder 12. The output end of the second cylinder 12 is fixedly connected to the limiting plate 13. The lower surface of the limiting plate 13 is slidably connected to the placement groove 11. By starting the second cylinder 12 to drive the limiting plate 13 to move, the disc brake pad can be laterally limited. The lower surface of the fixed plate 14 is fixedly connected to the fixed base 10. The upper surface of the fixed plate 14 is fixedly connected to the top plate 15. The lower surface of the top plate 15 is fixedly connected to the electric telescopic rod 16. The lower surface of the electric telescopic rod 16 is fixedly connected to the lower pressure plate 17. By starting the electric telescopic rod 16 to drive the lower pressure plate 17 to move, the disc brake pad can be longitudinally limited.

[0028] A support plate 18 is fixedly connected to the upper surface of the operating table 1. A third cylinder 19 is fixedly connected to the rear surface of the support plate 18. The second cylinder 12, the electric telescopic rod 16, and the third cylinder 19 are all electrically connected to an external power source. A placement box 20 is fixedly connected to the output end of the third cylinder 19. By starting the third cylinder 19, the placement box 20 can be moved to adjust its position, which in turn can adjust the position of the cutting head 23. A motor 21 is fixedly connected to the left inner wall of the placement box 20. The motor 21 is electrically connected to an external power source. A second rotating shaft 22 is fixedly connected to the output end of the motor 21. The side surface of the second rotating shaft 22 is rotatably connected to the placement box 20. The cutting head 23 is fixedly connected to the left surface of the second rotating shaft 22. By starting the motor 21, the second rotating shaft 22 and the cutting head 23 can be rotated to cut the disc brake pads.

[0029] Working principle: During use, two sets of disc brake pads to be cut are placed in the placement slot 11. The second cylinder 12 moves the limiting plate 13 to laterally limit the disc brake pads. The electric telescopic rod 16 moves the lower pressure plate 17 to longitudinally limit the disc brake pads. After the disc brake pads are limited, the third cylinder 19 moves the placement box 20 and the cutting head 23 to adjust the position of the cutting head 23. The motor 21 rotates the second shaft 22 and the cutting head 23 to cut the disc brake pads on the fixed seat 10 near the cutting head 23. After one set of disc brake pads is cut, the third cylinder 19 moves the placement box 20 and the cutting head 23 to the initial position. The first cylinder 3 moves the moving plate 4 and the rack 5. The rack 5 drives the first shaft 7, gear 8, and rotating plate 4. Rotating the rotating disc 9 allows the fixed seat 10 on another set of rotating discs 9 to move the cutting head 23 to one side for cutting. This process is repeated to cut the disc brake pads on the other set of fixed seats 10. Simultaneously, the disc brake pads from the previous set are unloaded, and the next set of disc brake pads is placed on the fixed seat 10 and positioned. In this structure, during the cutting of the first set of disc brake pads, the other set of positioning components 25 unloads and reloads the disc brake pads. Operators do not need to stop the machine to unload and load disc brake pads after each set of disc brake pads is cut, reducing downtime and improving the continuity of cutting production. This increases the cutting efficiency of disc brake pads. Furthermore, it allows for both lateral and longitudinal positioning of the brake pads, reducing positional shifts during cutting and improving cutting accuracy.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
