Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, and in particular to a clamping mechanism for processing brake parts. Background Technology

[0002] As a crucial component of vehicles and industrial equipment such as automobiles, motorcycles, and construction machinery, the quality of brake components directly impacts the braking performance and safety of the entire vehicle or equipment. The machining of brake components typically involves multiple processes, including drilling, milling, grinding, and turning. These processes require high precision, necessitating specialized clamping mechanisms to stably secure the brake components and ensure machining accuracy and efficiency.

[0003] A Chinese patent has been published: a clamping mechanism for machining mechanical parts, patent announcement number: CN221047853U. The patent "includes an operating table, four support columns are symmetrically arranged at the lower end of the operating table, a lifting frame is provided at the lower end of the operating table, a lifting plate is movably arranged in the lifting frame, support arms are fixedly connected to both ends of the lifting plate through the lifting frame, a rotating seat is rotatably connected to each support arm through a bearing, a drive chamber is provided in the lifting plate, and a dual-axis motor is provided in the drive chamber."

[0004] Although the equipment can clamp and fix mechanical parts of different widths and automatically flip them, the clamping mechanism cannot effectively clamp round machine parts. Because the clamping plate adopts a square structure, its clamping surface is flat and cannot fit tightly with the curved surface of the round part. The force-bearing area is limited and cannot provide sufficient friction, resulting in uneven distribution of clamping force. Under the action of strong cutting force, the part is prone to slippage, which reduces the machining accuracy. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a clamping mechanism for processing brake parts, so as to solve the problems that the clamping mechanism cannot effectively clamp circular machine parts, cannot fit tightly with the curved surface of circular parts, has a limited force area, and cannot provide sufficient friction, resulting in uneven distribution of clamping force.

[0006] To achieve the above objectives, this utility model provides a clamping mechanism for processing brake parts, including a grinding box. Both sides of the inner wall of the grinding box are fixedly connected to baffles. A perforated plate is fixedly connected inside the grinding box. A fixing plate is fixedly connected to the top of the perforated plate. A clamping mechanism for clamping brake parts is provided on the top of the perforated plate.

[0007] Preferably, the clamping mechanism includes three slide rods, which are fixedly connected to the top of a fixed plate. A fixed disk is fixedly connected between the top ends of the three slide rods. A threaded rod is rotatably connected between the opposite surfaces of the fixed disk and the fixed plate. A servo motor is fixedly connected to the bottom of the fixed plate, and the output end of the servo motor is fixedly connected to the bottom end of the threaded rod. A threaded disk is slidably connected between the outer walls of the three slide rods, and the threaded disk is threaded onto the outer wall of the threaded rod. Three evenly distributed fixed blocks are fixedly connected to the outer edge of the threaded disk. Two rotating plates are rotatably connected to the top of each fixed block. A limiting plate is rotatably connected inside one of the rotating plates, and one end of the limiting plate is rotatably connected to the outer edge of the fixed disk. A clamping block is rotatably connected between the top ends of the two rotating plates. A placement plate is fixedly connected to the top of the fixed disk.

[0008] Preferably, the outer wall of the fixed disk is fixedly connected with a shielding ring for shielding grinding debris via a support frame.

[0009] Preferably, the outer wall of the shielding ring is fixedly connected to an installation component, the side wall of the installation component is fixedly connected to a corrugated pipe, the bottom of the inner wall of the grinding box is slidably connected to a pull-out box, the inside of the pull-out box is fixedly connected to a water pump, and one end of the corrugated pipe is connected to the output end of the water pump.

[0010] Preferably, a filter screen is fixedly connected to the top of the inside of the pull-out box, and the filter screen is arc-shaped.

[0011] Preferably, the clamping block has an anti-slip groove at one end near the placement plate, and the groove is arc-shaped.

[0012] Preferably, the angle of the corrugated pipe near the shielding ring is inclined towards the top of the placement plate.

[0013] The beneficial effects of this utility model are:

[0014] 1. A clamping mechanism for machining brake parts. This clamping mechanism uses the rotation of a threaded rod to drive a threaded disc upward, which in turn drives the linkage of a fixed block, a rotating plate, and a clamping block, achieving uniform clamping force on the circular brake parts. The limiting plate provides a limiting function during the movement of the rotating plate, causing the rotating plate to rotate while rising, thereby driving the clamping block to rotate synchronously, enabling it to firmly clamp the three sides of the part. This clamping mechanism adopts a three-point clamping method, which effectively improves the stability of the part and avoids the problem of part slippage caused by uneven force in traditional clamping methods, thus improving the reliability of clamping and machining accuracy.

[0015] 2. This clamping mechanism for brake part processing utilizes a water pump and bellows to evenly spray water onto the parts being ground. This effectively reduces the surface temperature of the parts and suppresses dust generated during grinding, helping to maintain a clean working environment and reduce the risk of pollution. Simultaneously, the design of the shielding ring and filter effectively prevents water splashing and filters grinding debris, allowing water resources to be recycled and avoiding waste. This efficient water recycling and reuse not only reduces external water consumption and lowers operating costs, but also improves grinding efficiency and contributes to environmental protection and resource conservation.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0025] like Figures 1 to 4 As shown, a clamping mechanism for processing brake parts includes a grinding box 1. Baffles 2 are fixedly connected to both sides of the inner wall of the grinding box 1. A perforated plate 3 is fixedly connected inside the grinding box 1. A fixing plate 5 is fixedly connected to the top of the perforated plate 3. A clamping mechanism for clamping brake parts is provided on the top of the perforated plate 3.

[0026] Further, see attached document. Figure 2 and Figure 3 As shown, the clamping mechanism includes three slide rods 6, which are fixedly connected to the top of the fixed plate 5. A fixed plate 7 is fixedly connected between the top ends of the three slide rods 6. A threaded rod 8 is rotatably connected between the opposite surfaces of the fixed plate 7 and the fixed plate 5. A servo motor 9 is fixedly connected to the bottom of the fixed plate 5. The output end of the servo motor 9 is fixedly connected to the bottom end of the threaded rod 8. A threaded disc 10 is slidably connected between the outer walls of the three slide rods 6. The threaded disc 10 is threaded onto the outer wall of the threaded rod 8. Three evenly distributed fixed blocks 11 are fixedly connected to the outer edge of the threaded disc 10. Two rotating plates 12 are rotatably connected to the top of each fixed block 11. A limiting plate 13 is rotatably connected inside one of the rotating plates 12. One end of the limiting plate 13 is rotatably connected to the outer edge of the fixed plate 7. A clamping block 14 is rotatably connected between the top ends of the two rotating plates 12. A placement plate 15 is fixedly connected to the top of the fixed plate 7.

[0027] When using this clamping mechanism, first place the brake part to be ground on top of the placement plate 15. Then, start the servo motor 9 to drive the threaded rod 8 to rotate. The rotation of the threaded rod 8 causes the threaded disc 10 to move upward. At the same time, the rise of the threaded disc 10 further drives the three fixed blocks 11 on its outer edge to move upward synchronously. The movement of the fixed blocks 11 then pushes the rotating plate 12 to move upward. When the rotating plate 12 rises, it is limited by the limiting plate 13, so it not only continues to move upward but also rotates. As the rotating plate 12 rotates, the clamping block 14 rotates and gradually fits against the surface of the part, finally clamping the three sides of the part securely.

[0028] This clamping mechanism uses the rotation of the threaded rod 8 to drive the threaded disc 10 to move upward, and sequentially drives the fixed block 11, the rotating plate 12, and the clamping block 14 to achieve uniform clamping force on the circular brake part. The limiting plate 13 provides a limiting function during the movement of the rotating plate 12, so that the rotating plate 12 rotates while rising, thereby driving the clamping block 14 to rotate synchronously, so that it can firmly clamp the three sides of the part. This clamping mechanism adopts a three-point clamping method, which effectively improves the stability of the part and avoids the problem of part slippage caused by uneven force in traditional clamping methods, thereby improving the reliability of clamping and machining accuracy.

[0029] Further, see attached document. Figure 2 and Figure 4 As shown, the outer wall of the fixed plate 7 is fixedly connected to a shielding ring 16 for shielding grinding debris via a support frame. The outer wall of the shielding ring 16 is fixedly connected to a mounting piece 17. The side wall of the mounting piece 17 is fixedly connected to a corrugated pipe 18. The angle of the corrugated pipe 18 near the shielding ring 16 is inclined towards the top of the placement plate 15. The bottom of the inner wall of the grinding box 1 is slidably connected to a pull-out box 4. The inside of the pull-out box 4 is fixedly connected to a water pump 19. One end of the corrugated pipe 18 is connected to the output end of the water pump 19. The top of the inside of the pull-out box 4 is fixedly connected to a filter screen 20. The filter screen 20 is arc-shaped.

[0030] After the clamping mechanism securely holds the parts, the external grinding device can be activated or the fixed parts can be ground manually. During the grinding process, the water pump 19 is activated to draw water from the pull-out box 4 and deliver it to the corrugated pipe 18. Subsequently, the water is evenly sprayed onto the surface of the parts being ground through the corrugated pipe 18 to achieve cooling and dust suppression effects. At the same time, the debris generated during the grinding process falls down with the water flow and is blocked by the baffle ring 16, causing it to fall orderly onto the top of the filter screen 20. The filter screen 20 effectively intercepts the debris in the water and gathers it together by its own shape, ensuring that the clean water can flow back into the pull-out box 4 for recycling. This design not only effectively saves water resources and reduces unnecessary waste, but also keeps the grinding environment clean and improves processing efficiency and the surface quality of the parts.

[0031] Through the coordinated operation of the water pump 19 and the bellows 18, water can be evenly sprayed onto the parts being polished. This not only effectively reduces the surface temperature of the parts but also suppresses dust generated during polishing, helping to maintain a clean working environment and reduce the risk of pollution. At the same time, the design of the shielding ring 16 and the filter screen 20 effectively prevents water splashing and filters the debris generated during polishing, allowing water resources to be recycled and avoiding waste. This efficient recycling and reuse of water resources not only reduces the consumption of external water sources but also lowers operating costs. It not only improves polishing efficiency but also contributes to environmental protection and resource conservation.

[0032] Further, see attached document. Figure 2 and Figure 3 As shown, the clamping block 14 has an anti-slip groove at one end near the placement plate 15 and is arc-shaped. The anti-slip groove at one end of the clamping block 14 increases the friction with the part, and the shape increases the clamping area of ​​the round part, making it more stable.
