Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary clamping platform technology, and in particular to a turntable device for clamping brake discs. Background Technology
[0002] With industrialization and the popularization of new energy vehicles, the automobile manufacturing industry has also developed rapidly. Brake discs are an important component of automobile braking systems.
[0003] Currently, during the production process of brake discs, a spray coating is applied to the surface of the brake discs to improve their performance and service life, thereby enhancing their corrosion resistance, improving heat dissipation, and reducing braking noise.
[0004] The conventional brake disc spraying process involves clamping the brake disc horizontally, feeding it into the spraying chamber, and rotating it along its central axis to spray the disc surface. However, this method still has the following drawbacks: because the brake disc is placed horizontally and the spraying material falls due to its own weight, the spraying effect on the lower surface of the brake disc is deteriorated.

The extension rod extends downward through the gear ring seat and is fixedly connected to the base plate. An upper bearing seat is fixedly mounted on the upper end of the extension rod, and an upper bearing is mounted inside the upper bearing seat.
[0017] The gear ring seat has a lower bearing installed in the lower bearing housing.
[0018] Furthermore, the star wheel assembly includes:
[0019] A star wheel meshes with a planetary wheel. A drive shaft is coaxially mounted on the star wheel. The drive shaft is inserted into an upper bearing and a lower bearing. The lower end of the drive shaft is connected to a drive motor. A fixed disk is fixedly mounted on the upper part of the drive shaft. A hinge seat is provided at the edge of the fixed disk.

[0024] 2. Through the mutual sliding cooperation of the limit rod and slide rail, the workpiece undulates along the axis of the hinge seat during rotation, allowing the brake disc to be sprayed to a greater extent. Attached Figure Description

[0040] To more clearly and explicitly illustrate the specific implementation objectives and methods of this utility model, the technical solution of this utility model will be fully described below. The described embodiments are only some embodiments of this utility model, not all embodiments. Without creative effort, all other embodiments based on the described embodiments of this utility model are within the protection scope of this utility model.
[0041] This utility model discloses a turntable device for clamping a brake disc, such as... Figure 1As shown, it includes: a support frame 10, a base plate 11 fixedly disposed on the upper end of the support frame 10, a drive motor 12 fixedly disposed at the center of the lower end of the base plate 11, and a planetary gear mechanism 2 disposed on the base plate 11.
[0042] The planetary gear mechanism 2 is used to rotate the clamped workpiece and swing along the central axis, and includes: a gear ring assembly 21, a planetary gear assembly 22, and a star gear assembly 23.
[0043] The gear ring assembly 21, as Figure 2 As shown, it includes:
[0044] A gear ring seat 210 is fixedly mounted on the base plate 11. A lower bearing seat is provided in the center of the inner bottom of the gear ring seat 210. A gear ring 211 is rotatably mounted inside the gear ring seat 210. An extension cylinder 212 is coaxially and fixedly mounted on the upper end of the gear ring 211. A slide 213 is provided on the outer wall of the upper part of the extension cylinder 212. The slide 213 is designed to be undulating and wave-shaped. An observation groove 214 is provided through the extension cylinder 212. Multiple observation grooves 214 are arranged in a circular array along the central axis of the extension cylinder 212.
[0045] The planetary gear assembly 22 is set to rotate, such as Figure 3 As shown, it includes:
[0046] A planetary gear 220 meshes with a gear ring 211, and an extension rod 221 is coaxially rotatably mounted on the planetary gear 220.
[0047] Two retaining rings are snapped onto the extension rod 221, and they respectively abut against the upper and lower ends of the planetary gear 220. The retaining rings are used to limit the position of the planetary gear 220 on the extension rod 221, and prevent the planetary gear 220 from losing its teeth due to vertical displacement when rotating on the extension rod 221. The extension rod 221 extends downward through the gear ring seat 210 and is fixedly connected to the base plate 11. An upper bearing seat 222 is fixedly provided at the upper end of the extension rod 221, and an upper bearing 224 is provided inside the upper bearing seat 222. A lower bearing 223 is provided inside the lower bearing seat of the gear ring seat 210.
[0048] The star wheel assembly 23, such as Figure 4 As shown, it includes:
[0049] A star gear 230 meshes with the planetary gear 220. A drive shaft 231 is coaxially mounted on the star gear 230. The drive shaft 231 is inserted into the upper bearing 224 and the lower bearing 223. The lower end of the drive shaft 231 is connected to the drive motor 12. A fixed disk 232 is fixedly mounted on the upper part of the drive shaft 231. A hinge seat 233 is provided at the edge of the fixed disk 232. A protective rod 236 extends upward from the center of the fixed disk 232. A protrusion is provided at the upper end of the protective rod 236.
[0050] like Figure 4 As shown, a chuck 3 is coaxially driven and hinged on the star wheel assembly 23. The chuck 3 is mounted on the hinge seat 233. A clamping arm 30 is provided on the jaw of the chuck 3. A mounting seat 31 is fixedly provided on the side wall of the chuck 3. A limit rod 32 is fixedly provided on the mounting seat 31. The limit rod 32 is inclined and the end of the limit rod 32 is horizontal and is movably inserted into the slide rail 213.
[0051] The hinge seat 233 and the mounting seat 31 are respectively located on both sides of the central axis of the chuck 3.
[0052] Based on the specific structure of the turntable device for clamping a brake disc in the above embodiments, its working process will be further explained below:
[0053] The workpiece is placed into the chuck 3 through the protective rod 236 and reliably fixed by the clamping arm 30. The drive motor 12 rotates, driving the transmission shaft 231 to rotate, thereby causing the chuck 3 and the workpiece fixed on it to rotate in the forward direction. At the same time, through the transmission of the planetary gear mechanism, the extension cylinder 212 rotates in the reverse direction. At this time, the slide 213 and the limit rod 32 rotate in opposite directions, causing the chuck 3 to move up and down along the hinge seat 233. Finally, the workpiece fixed on the chuck 3 swings and rotates. The upward-extending protective rod 236 prevents the workpiece swinging and rotating on the chuck 3 from being thrown out and causing a safety accident.
[0054] Based on the above, and inspired by an embodiment of the turntable device for clamping a brake disc of this utility model, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
