[0001] This utility model relates to the field of machining equipment technology, and in particular to a tooling for machining brake discs. Background Technology
[0002] In the brake disc manufacturing process, precise machining of the disc surface, such as disc polishing and machining of ventilation holes in ventilated brake discs, is a crucial step in ensuring brake disc performance and quality. However, existing brake disc machining tooling has many shortcomings, affecting machining efficiency and quality.
[0003] Traditional brake disc machining fixtures can only clamp the brake disc in a simple way, and cannot achieve rotation or precise positioning of the brake disc. When multi-angle machining of the brake disc surface is required, operators usually need to manually adjust the position of the brake disc, which not only increases the difficulty and labor intensity of operation, but also easily leads to a decrease in machining accuracy due to human error, affecting product quality.
[0004] Therefore, it is necessary to propose a brake disc machining fixture to overcome the above-mentioned defects. Utility Model Content

The base plate and the top plate are fixedly connected by a support column. A lifting and rotating mechanism is provided between the base plate and the top plate. A limit stop is provided on the top plate. After the lifting and rotating mechanism rotates the brake disc by a set angle, it lifts the disc and abuts against the limit stop. The lifting and rotating mechanism includes a guide column and a lifting cylinder disposed on the base plate. A lifting plate is slidably disposed on the guide column. The lifting plate is connected to the piston rod of the lifting cylinder. A lifting shaft is disposed on the lifting plate. The lower end of the lifting shaft is rotatably connected to the lifting plate, and the upper end passes through the top plate and is provided with a tray. A steering cylinder is disposed on the top plate. A rack is disposed on the piston rod of the steering cylinder. A gear ring that cooperates with the rack is disposed on the lifting shaft.
[0007] Furthermore, the lower end of the lifting shaft is fixedly connected to the lifting plate, and a steering sleeve is provided on it. The top plate is provided with an arc-shaped guide groove coaxial with the lifting shaft. A steering support rod passing through the arc-shaped guide groove is provided on the steering sleeve. A support platform is provided at one end of the steering support rod passing through the top plate. The steering sleeve is held on the top plate by the steering support rod and the support platform. The rack meshes with the outer cylindrical surface of the steering sleeve.
[0008] Furthermore, a limiting mechanism is provided within the guide groove. The limiting mechanism includes a sliding plate, on which a telescopic tube passes through the arc-shaped guide groove. An unlocking push rod and a locking spring are provided within the telescopic tube. The upper end of the unlocking push rod passes through the sliding plate, and the lower end is provided with a locking plate. The upper end of the locking spring is connected to the sliding plate, and the lower end is connected to the locking plate. The side of the top plate adjacent to the locking plate is a mating friction surface. The rack is slidably mounted on the piston rod of the steering cylinder, and a buffer spring is provided between the rack and the piston rod of the steering cylinder.
[0009] Furthermore, a torsion spring is provided inside the steering sleeve, with one end of the torsion spring connected to the inner wall of the steering sleeve and the other end connected to the top plate, and the steering cylinder is mounted on the lifting plate.
[0010] Furthermore, a copper sleeve is provided inside the lifting plate, the guide column is slidably disposed inside the copper sleeve, and a limiting buffer block made of elastic material is provided on the lifting plate.

[0019] 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 the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0020] Example 1
[0021] Reference Figure 1 This utility model provides a tooling for processing brake discs, including a base plate 1 and a top plate 2. The base plate 1 and the top plate 2 are fixedly connected by a support column 101. A guide column 102 and a lifting cylinder are located on the base plate 1. The guide column 102 is positioned between the base plate 1 and the top plate 2, and a lifting plate 103 is slidably mounted on it. A copper sleeve 105 is disposed inside the lifting plate 103, and the guide column 102 is slidably positioned within the copper sleeve 105. The copper sleeve 105 has good lubrication and wear resistance. The lifting plate 103 is equipped with a lifting shaft 106 and a limit buffer block 104 made of elastic material, which are used to buffer when the lifting plate 103 rises to the limit position. The lower end of the lifting shaft 106 is rotatably connected to the lifting plate 103, and the upper end passes through the top plate 2 and is equipped with a tray 4, which is used to place the brake disc. A steering cylinder 3 is installed on the top plate 2, and a rack 301 is installed on the piston rod of the steering cylinder 3. A gear ring 107 that cooperates with the rack 301 is installed on the lifting shaft 106.
[0022] Reference Figure 5 During operation, the brake disc 7 is placed on the tray 4. In practical applications, in order to improve the stability of the brake disc 7, the tray 4 is provided with a positioning post that matches the threaded hole of the brake disc 7. The lifting cylinder drives the lifting plate 103 to slide on the guide post 102, thereby realizing the lifting of the lifting shaft 106. The top plate 2 is provided with a limit card 201. When the lifting cylinder rises, it lifts the brake disc and presses it against the limit card 201 to fix the brake disc.
[0023] When the brake disc 7 needs to be rotated, the lifting plate 103 descends to engage the gear ring 107 with the rack 301, and the extension and retraction of the steering cylinder 3 drives the lifting shaft 106 to rotate, thereby realizing the rotation of the tray 4 and the brake disc 7 on it; after the steering is completed, the lifting plate 103 rises to disengage the gear ring 107 from the rack 301, and the steering cylinder 3 resets so that it will not drive the lifting shaft 106 to rotate.
[0024] Example 2
[0025] Reference Figure 2 , Figure 3 Based on Embodiment 1, to improve the stability of the brake disc 7 during steering, the lower end of the lifting shaft 106 is fixedly connected to the lifting plate 103, and a steering sleeve 6 is installed on it; the top plate 2 is provided with an arc-shaped guide groove 202 coaxial with the lifting shaft 106, and a steering support rod 601 passing through the arc-shaped guide groove 202 is provided on the steering sleeve 6. A support platform 602 is provided at one end of the steering support rod 601 passing through the top plate 2 for supporting and fixing the brake disc. The steering sleeve 6 is held on the top plate 2 by the steering support rod 601 and the support platform 602, and the steering cylinder 3 is provided on the top plate 2, with the rack 301 meshing with the outer cylindrical surface of the steering sleeve 6.
[0026] When it is necessary to rotate the brake disc 7, the lifting plate 103 lowers and places the brake disc 7 on the support platform 602. The tray 4 disengages from the brake disc 7, and the steering cylinder 3 drives the steering sleeve 6 to rotate, which in turn drives the brake disc to rotate through the steering support rod 601 and the support platform 602. After the rotation is completed, the lifting cylinder rises and lifts the brake disc to abut against the limit card 201, thereby fixing the brake disc. At this time, the steering cylinder 3 drives the steering sleeve 6 to reset.
[0027] Example 3
[0028] Reference Figure 2 , Figure 4 Based on Embodiment 2, in order to achieve adjustable rotation angle of brake disc 7, a limiting mechanism 5 is installed in the arc-shaped guide groove 202 to limit the rotation range of steering sleeve 6. Specifically, the limiting mechanism 5 includes a slide plate 501, on which a telescopic tube 502 passing through the arc-shaped guide groove 202 is provided. An unlocking push rod 504 and a locking spring 505 are provided in the telescopic tube 502. The upper end of the unlocking push rod 504 passes through the slide plate 501, and the lower end is provided with a locking disc 503. The upper end of the locking spring 505 is connected to the slide plate 501, and the lower end is connected to the locking disc 503. The side of the top plate 2 adjacent to the locking disc 503 is a friction surface that cooperates with each other. Under the tension of the locking spring 505, the top plate 2 and the locking disc 503 are pressed together, thereby fixing the limiting mechanism 5 in the arc-shaped guide groove 202.
[0029] When the steering sleeve 6 rotates to the set angle, the steering support rod 601 abuts against the slide plate 501 and the locking plate 503, thereby restricting the steering sleeve 6 from continuing to rotate; in cooperation with this, the rack 301 is slidably mounted on the piston rod of the steering cylinder 3, and a buffer spring is provided between the rack 301 and the piston rod of the steering cylinder 3; when it is necessary to adjust the rotation angle, the unlocking push rod 504 is pressed down to disengage the locking plate 503 from the top plate 2, which can push the limiting mechanism 5 to slide in the arc-shaped guide groove 202.
[0030] To improve efficiency, a torsion spring 603 is installed inside the steering sleeve 6. One end of the torsion spring 603 is connected to the inner wall of the steering sleeve 6, and the other end is connected to the top plate 2. At the same time, the steering cylinder 3 is installed on the lifting plate 103. When the lifting plate 103 descends, the steering sleeve 6 engages with the rack 301, which can drive the brake disc 7 to rotate and rotate the torsion spring 603. When the lifting plate 103 rises, the steering sleeve 6 disengages from the rack 301, and the steering sleeve 6 automatically resets under the action of the torsion spring 603.
[0031] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
