Description

Technical Field

[0001] This utility model belongs to the field of automotive disc brake disc manufacturing technology, specifically relating to an adjustable positioning device for automotive disc brake disc manufacturing. Background Technology

[0002] In the automotive manufacturing industry, the braking system is a core component related to driving safety, with disc brake discs playing a crucial role. Disc brake discs need to provide stable and reliable braking torque and heat dissipation performance under extreme conditions (high speed, high temperature, high load, frequent braking). Their manufacturing quality, especially key geometric dimensions (such as mounting surface flatness, parallelism, thickness tolerance, friction surface runout, and center hole / bolt hole position accuracy) and surface quality (such as friction surface roughness and absence of stress concentration defects), directly determines the vehicle's braking performance, NVH (noise, vibration, and harshness) performance, and service life. Disc brake discs are typically made of gray cast iron, ductile iron, or composite materials (such as carbon ceramic). The manufacturing process mainly involves casting, rough machining, heat treatment (such as quenching and tempering), finish machining (turning, grinding, drilling / tapping), dynamic balancing, cleaning, and inspection. Among these machining processes, especially the finish machining stage (such as turning friction surfaces, grinding end faces, and drilling), precise positioning is the prerequisite and key to ensuring that the final product meets stringent tolerance requirements.

[0003] Traditional positioning devices cannot flexibly adapt to disc brake discs of different diameters or thicknesses, resulting in frequent fixture changes. Furthermore, disc brake discs often have irregular structures such as ventilation holes and grooves around their periphery, which can easily cause positioning misalignment or damage to the workpiece with traditional rigid fixtures. In addition, existing multi-point fixtures require individual adjustments, which is time-consuming and makes it difficult to ensure symmetry. This phenomenon has become a problem that urgently needs to be solved by those in the field. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable positioning device for manufacturing automotive disc brake discs, including a positioning disc. The upper end face of the positioning disc has four sets of arc-shaped slots evenly distributed in a ring around the center of the positioning disc. Adjusting blocks are provided at the positions corresponding to the arc-shaped slots on the upper end face of the positioning disc.

Two sets of rollers are provided on the side of the calibration plates near the center of the positioning disc. Sliding blocks are provided at the positions corresponding to each set of adjusting blocks on the lower end face of the positioning disc. A circular plate is bolted to the middle of the lower end of the positioning disc. An annular plate is fixed to the lower end face of the circular plate. An arc cylinder communicating with the inside of the annular plate is fixed to the outer wall of the annular plate at the position corresponding to each set of arc-shaped slots. An I-shaped block is provided at the position between the four sets of sliding blocks and located inside the annular plate. Four pull ropes are fixed to the periphery of the I-shaped block, passing through the arc cylinder and fixedly connected to the corresponding sliding block.

[0006] This utility model further explains that a retaining ring is fixed on the side of the calibration plate opposite to the roller and is sleeved on the adjusting block. The retaining ring is connected to the adjusting block by bolts. The shaft fixed on the lower end face of the adjusting block passes through the arc-shaped slot and is connected to the corresponding sliding block by bolts. Locking feet are bolted to the four opposite corners of the lower end of the positioning plate.

[0007] The present invention further explains that positioning holes are provided on the side walls of the calibration plates located on both sides of the adjustment block, and positioning rods that slide through the inside of the positioning holes are fixed on the housings of the rollers, and a baffle is bolted to the end face of each positioning rod that passes through the positioning hole.

[0008] The present invention further explains that a spring is sleeved on the positioning rod located between the calibration plate and the roller, and the two ends of each spring abut against the side wall of the calibration plate and the roller, respectively.

[0009] The present invention further describes that a linkage rotating plate is provided at the position directly below the circular plate. Multiple sets of teeth are evenly distributed in a ring along the periphery of the linkage rotating plate on the outer wall of the upper surface of the linkage rotating plate. Four sets of blocks are fixed on the lower end surface of the positioning plate, and each block has a toothed block fixed on its lower end surface for meshing with the teeth.

[0010] This utility model further explains that an assembly ring is bolted to the lower end face of the ring plate, and a movable column passing through the inner side of the assembly ring is fixed to the lower end face of the I-shaped block. A convex groove is opened inside the movable column, passing through the lower end face of the movable column.

Detailed Implementation

[0026] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-8This utility model provides a technical solution: an adjustable positioning device for manufacturing automotive disc brake discs, including a positioning disc 1. The upper surface of the positioning disc 1 has four sets of arc-shaped slots 103 evenly distributed in a ring around the center of the positioning disc 1. Adjusting blocks 3 are provided at positions corresponding to the arc-shaped slots 103 on the upper surface of the positioning disc 1. Calibration plates 2 are provided on the outer side of each adjusting block 3 near the center of the positioning disc 1. Two sets of rollers 203 are provided on the side of each calibration plate 2 near the center of the positioning disc 1. Sliding blocks 4 are provided at positions corresponding to each set of adjusting blocks 3 on the lower surface of the positioning disc 1. A circular plate 5 is bolted to the center of the lower end of the positioning disc 1. A ring plate 502 is fixed to the lower surface of the circular plate 5. An arc cylinder 503 communicating with the interior of the ring plate 502 is fixed at positions corresponding to each set of arc-shaped slots 103 on the outer wall of the ring plate 502. A position is provided between the four sets of sliding blocks 4. An I-shaped block 402 is placed inside the ring plate 502. Four pull ropes 403 are fixed around the periphery of the I-shaped block 402, passing through the arc cylinder 503 and fixedly connected to the corresponding sliding block 4. A retaining ring 202 is fixed on the side of the calibration plate 2 opposite to the roller 203 and is sleeved on the adjusting block 3. The retaining ring 202 is connected to the adjusting block 3 by bolts. The shaft fixed on the lower end face of the adjusting block 3 passes through the arc-shaped slot 103 and is connected to the corresponding sliding block 4 by bolts. Locking feet 101 are bolted to the four opposite corners of the lower end of the positioning plate 1. An arc hole 401 is opened through the surface of the sliding block 4 located below the pull rope 403. An arc rod 504 is fixed on the lower end face of the outer side of the arc cylinder 503 and slides through the corresponding arc hole 401. A second spring 406 is sleeved on each arc rod 504, and the two ends of the second spring 406 abut against the side wall of the sliding block 4 and the end face of the arc cylinder 503, respectively.

[0028] With the above structure in place, the disc brake disc is positioned at the center of the upper part of the positioning disc 1, and multiple calibration plates 2 are located around the disc brake disc. Therefore, after the I-shaped block 402 is rotated, the I-shaped block 402 will synchronously wind up multiple pull ropes 403. As a result, the pull ropes 403 will pull and move the sliding block 4, which will then slide along the arc-shaped opening 103. The sliding block 4 will also drive the adjusting block 3 to move along the arc-shaped opening 103 and control the calibration plates 2 to move towards the disc brake disc. This will control multiple rollers 203 to clamp the disc brake disc from multiple directions, thereby ensuring the stability of the disc brake disc at the upper part of the positioning disc 1. Furthermore, by adjusting the position of the calibration plates, the position of disc brake discs of different sizes can be adjusted.

[0029] When the sliding block 4 moves toward the ring plate 502, the sliding block 4 will compress the second spring 406. Therefore, the second spring 406 will slide along the arc path of the arc rod 504. At the same time, the arc rod 504 limits the second spring 406 to ensure that the second spring 406 will not bend excessively. When the I-shaped block 402 is released, the second spring 406 will push the sliding block 4 to return to its original position, thereby controlling the calibration plate 2 to move away from the peripheral position of the disc brake disc, thereby releasing the disc brake disc.

[0030] At the same time, each calibration plate 2 is used in conjunction with two sets of rollers 203. Therefore, when the rollers 203 first come into contact with the periphery of the disc brake disc, the calibration plate 2 will continue to move a distance towards the disc brake disc. Thus, the distance between the rollers 203 and the calibration plate 2 is adjusted. Since the adjustment distances between the two sets of rollers 203 and the calibration plate 2 are different, it is possible to connect with the irregular shapes of the disc brake disc periphery, so as to adapt to disc brake discs of different shapes.

[0031] Positioning holes 201 are provided on the side walls of the calibration plate 2 located on both sides of the adjusting block 3. Positioning rods 204 that slide through the inside of the positioning holes 201 are fixed on the housing of the rollers 203. Each positioning rod 204 is bolted to the end face of the positioning rod 204 that passes through the positioning hole 201. A spring 205 is sleeved on the positioning rod 204 located between the calibration plate 2 and the rollers 203. The two ends of each spring 205 abut against the side walls of the calibration plate 2 and the rollers 203, respectively.

[0032] With the above structure in use, when the distance between the roller 203 and the calibration plate 2 is adjusted, the positioning rod 204 will slide along the inner side of the positioning hole 201, and the roller 203 will compress the spring 205. Therefore, when the calibration plate 2 moves away from the disc brake disc, the spring 205 will push the roller 203 to reset, thereby controlling the distance between the roller 203 and the calibration plate 2 to reset to the initial position.

[0033] A linkage rotating plate 6 is located directly below the circular plate 5. The outer wall of the upper end face of the linkage rotating plate 6 has multiple sets of teeth 601 evenly distributed in a ring around the periphery of the linkage rotating plate 6. Four sets of square blocks 102 are fixed to the lower end face of the positioning plate 1, and each square block 102 has a toothed block 104 fixed to its lower end face to mesh with the teeth 601. An assembly ring 501 is bolted to the lower end face of the ring plate 502. A movable column 404 passing through the inner side of the assembly ring 501 is fixed to the lower end face of the I-shaped block 402. A convex groove 405 penetrating the lower end face of the movable column 404 is opened inside the movable column 404. A T-shaped rod 602 located inside the convex groove 405 is fixed to the upper end face of the linkage rotating plate 6. A spring 603 located inside the convex groove 405 is sleeved on the surface of the T-shaped rod 602. The convex strip on the inner wall of the convex groove 405 cooperates with the groove on the surface of the T-shaped rod 602.

[0034] With the above-described structure, when it is necessary to control the rotation of the I-shaped block 402 within the ring plate 502, the linkage rotating plate 6 can be controlled to move downwards. This causes the linkage rotating plate 6 to drive the T-shaped rod 602 downwards within the convex groove 405. Consequently, the T-shaped rod 602 compresses the spring 603, and simultaneously, the toothed edge 601 on the linkage rotating plate 6 disengages from the toothed block 104. At this point, when controlling the rotation of the linkage rotating plate 6, it passes through the groove on the periphery of the T-shaped rod 602. The convex strip inside the convex groove 405 rotates, and the movable column 404 controls the rotation of the I-shaped block 402. When the I-shaped block 402 controls the adjusting block 3 to move to the corresponding position, the linkage rotating plate 6 is released. As a result, the spring 3 603 pushes the T-shaped rod 602 to reset upwards and controls the linkage rotating plate 6 to reset upwards. Thus, the linkage rotating plate 6 drives the toothed mouth 601 to re-mesh with the toothed block 104, ensuring that the linkage rotating plate 6 will not rotate easily, thereby ensuring that the position of the I-shaped block 402 remains unchanged.
