Description

Technical Field

[0001] This utility model relates to the field of disc brake disc positioning technology, and more specifically, to a positioning fixture for manufacturing motorcycle disc brake discs. Background Technology

[0002] In modern motorcycle manufacturing, disc brake discs are a key safety component, and their manufacturing precision and quality directly affect the braking performance and driving safety of motorcycles. During the manufacturing process, disc brake discs require precise positioning and fixation for subsequent processing.

[0003] A search revealed that patent application CN202420419087.5 discloses a quick-clamping fixture for disc brake disc processing, comprising a support platform, a support ring fixed to the surface of the support platform, a positioning rod inserted inside the support ring, a trapezoidal positioning block fixed to the inner end of the positioning rod, a cylinder fixed to the bottom of the support platform, a conical column fixed to the end of the cylinder's push rod, and a brake disc tightly fixed to the outer surface of the trapezoidal positioning block. After the brake disc is fitted onto the surface of the trapezoidal positioning block, the conical column is lifted by the cylinder, which in turn causes the trapezoidal positioning block to expand and fix the brake disc. However, this method still has the following drawbacks:

[0004] (1) The clamping fixtures in the prior art can only position and fix the disc brake disc. In the prior art, most of the brake discs are manufactured by drilling with a single drilling device. After a single drilling is completed, the disc brake disc needs to be removed from the fixture manually, and the drilling position is changed by manually rotating the brake disc before it is fixed, resulting in low manufacturing efficiency.

[0005] The height of the tooling in the existing technology is constant, making it difficult to flexibly adjust the height of the positioning tooling according to actual manufacturing needs, resulting in poor applicability.

[0006] Therefore, we have made improvements to this and proposed a positioning fixture for manufacturing motorcycle disc brake discs. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figures 1 to 6 As shown, the positioning fixture for manufacturing motorcycle disc brake discs proposed in this embodiment includes a support plate 1. A first bracket 2 is fixedly connected to the lower end face of the support plate 1. A first bearing 3 is fixedly connected to the center of the first bracket 2.

A second bracket 11 is provided on the lower side of the first bracket 2. A base plate 12 is fixedly connected to the bottom end of the second bracket 11. A second bearing 13 is fixedly connected to the center of the second bracket 11. A rotating tube 14 is fixedly connected to the inner wall of the inner ring of the second bearing 13. The bottom end of the rotating tube 14 passes through the second bracket 11. A splined shaft 15 is slidably connected in the rotating tube 14. The top end of the spline shaft 15 is fixedly connected to the lower end face of the first bracket 2. The bottom of the spline shaft 15 is provided with a height adjustment mechanism 16. A first worm gear 17 is fixedly connected to the rotating tube 14. A first connecting frame 18 is fixedly connected to the second bracket 11. A first motor 19 is fixedly connected to the first connecting frame 18. A first worm 20 that meshes with the first worm gear 17 is fixedly connected to the drive end of the first motor 19. The turntable 5 is driven to rotate by the power mechanism 6. The arc-shaped opening 8 on the turntable 5 cooperates with the straight opening 7 on the bearing plate 1, so that the slider 9 slides in the opening, driving the clamping column 10 to move, thereby achieving the clamping and positioning of the disc brake disc. The first motor 19 drives the first worm 20 to rotate. The first worm 20 drives the first worm gear 17 to rotate, which in turn drives the rotating tube 14 to rotate. The rotation of the rotating tube 14 drives the spline shaft 15 to rotate. The rotation of the spline shaft 15 drives the first bracket 2 and the bearing plate 1 to rotate, which can realize the overall rotation of the disc brake disc, making it convenient to process different positions of the disc brake disc without manual adjustment.

[0031] like Figure 1 and Figure 4As shown, in a preferred embodiment, based on the above method, the power mechanism 6 further includes a second worm gear 601 fixed on the rotating shaft 4, a second connecting frame 602 fixedly connected to the first bracket 2, a second motor 603 fixedly connected to the second connecting frame 602, and a second worm 604 meshing with the second worm gear 601 fixedly connected to the drive end of the second motor 603; the second motor 603 drives the second worm 604 to rotate, the second worm 604 drives the second worm gear 601 to rotate, the second worm gear 601 drives the rotating shaft 4 to rotate, and thus drives the turntable 5 to rotate.

[0032] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, the height adjustment mechanism 16 further includes a power motor 1601 fixed on the chassis 12. The drive end of the power motor 1601 is fixedly connected to a threaded rod 1602. The top end of the threaded rod 1602 is rotatably connected to the second bracket 11 through a bearing. A height adjustment plate 1603 is threadedly connected to the threaded rod 1602. A third bearing 1604 is fixedly connected to the upper end face of the height adjustment plate 1603. The inner sidewall of the inner ring of the third bearing 1604 is fixedly connected to the bottom end of the spline shaft 15. The power motor 1601 drives the threaded rod 1602 to rotate, and the threaded rod 1602 drives the height adjustment plate 1603 to move up and down. The height adjustment plate 1603 drives the spline shaft 15 to move up and down through the third bearing 1604, thereby adjusting the height of the first bracket 2 and the clamping column 10. The height adjustment can be precisely controlled to meet the processing requirements of disc brake discs of different specifications.

[0033] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, a guide rod 1605 is slidably connected to the end of the height adjustment plate 1603 away from the threaded rod 1602. The upper and lower ends of the guide rod 1605 are fixedly connected to the second bracket 11 and the chassis 12, respectively. A limit ring 1606 is fixedly connected to the guide rod 1605. The guide rod 1605 plays a guiding role to ensure the stability of the movement of the height adjustment plate 1603, and the limit ring 1606 can prevent the height adjustment plate 1603 from moving excessively.

[0034] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, four mounting holes 21 are evenly provided on the chassis 12, and the cross-sectional shape of the chassis 12 is circular; the circular chassis 12 has a simple structure and is easy to install, and the four mounting holes 21 can provide stable fixing points.

[0035] like Figure 1 and Figure 6As shown, in a preferred embodiment, based on the above method, the number of clamping posts 10 is further four, and each of the four clamping posts 10 has a clamping groove at its top. The four clamping posts 10 can evenly distribute the clamping force to ensure the accuracy of the disc brake disc positioning. The clamping groove can increase the contact area with the disc brake disc and improve the stability of clamping.

[0036] Specifically, the positioning fixture used in the manufacturing of this motorcycle disc brake disc works as follows: First, adjust the spacing between the four clamping posts 10 according to the size of the disc brake disc, making the spacing slightly larger than the size of the disc brake disc. Then, place the disc brake disc in the clamping groove of the clamping post 10. Next, the second motor 603 drives the second worm gear 604 to rotate, which in turn drives the second worm wheel 601 to rotate. The second worm wheel 601 drives the rotating shaft 4 to rotate, which in turn drives the turntable 5 to rotate. The arc-shaped opening 8 on the turntable 5 matches the straight opening 7 on the bearing plate 1, allowing the slide head 9 to slide within the opening, thus moving the clamping posts 10 and achieving the clamping and positioning of the disc brake disc. When the height needs to be adjusted, the power motor... 1601 drives the threaded rod 1602 to rotate, which in turn drives the height adjustment plate 1603 to move up and down. The height adjustment plate 1603 drives the spline shaft 15 to move up and down via the third bearing 1604, thereby adjusting the height of the first bracket 2 and the bearing plate 1. This allows for the adjustment of the disc brake disc's height. When the disc brake disc needs to be rotated for position adjustment, the first motor 19 drives the first worm gear 20 to rotate, which in turn drives the first worm wheel 17 to rotate, which in turn drives the rotating tube 14 to rotate. The rotation of the rotating tube 14 drives the spline shaft 15 to rotate, which in turn drives the first bracket 2 and the bearing plate 1 to rotate, thus achieving overall rotation of the disc brake disc and realizing automated rotation position adjustment.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
