Description

Technical Field

[0001] This utility model relates to the field of automotive parts surface treatment technology, and in particular to a rotating device for coating tooling. Background Technology

[0002] In the automotive lighting industry, the headlight covers need to be aluminum-plated during production to form a reflective or decorative surface. The main function of the coating fixture is to load the parts to be coated and fix them at a good coating angle to prevent them from shaking inside the coating machine.

[0003] Automobiles come in a wide variety of specifications, and therefore, headlight covers also come in various forms. When coating headlight covers of different specifications, different coating fixtures need to be switched to fit and fix them to meet production needs. However, existing coating fixtures are either welded and fixed, which is not conducive to storage and replacement, or the installation and connection between parts are cumbersome, which is not conducive to quick assembly and disassembly, thus affecting production efficiency. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies where different coating fixtures are required to be switched and fixed when coating different specifications of car headlight covers to meet production needs. However, existing coating fixtures are either welded and fixed, which is inconvenient for storage and replacement, or the installation and connection between components are cumbersome, hindering quick assembly and disassembly and affecting production efficiency. This invention provides a rotating frame device for coating fixtures.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a rotating frame device for coating tooling, including two supporting discs arranged opposite each other, a rotating central shaft fixedly connected to each of the two supporting discs, a connecting frame between the two supporting discs, the connecting frame including two supporting plates arranged opposite each other, each supporting plate consisting of three wing plates, with adjacent wing plates forming a V-shaped structure, a connecting hole in the center of the supporting plate that mates with the rotating central shaft, a bolt threaded into the connecting hole and connected to the rotating central shaft, a through hole at the end of the wing plate away from the connecting hole, multiple supporting columns snapped between the two supporting plates, and a tooling piece inserted between the two wing plates in the same vertical direction.

[0006] The rotating central shaft is used to connect to the coating machine; the connecting frame is connected to the rotating central shaft by bolts passing through the connecting holes; both support plates consist of three wing plates, allowing the upper and lower ends of the fixture to connect to the corresponding three sets of wing plates, facilitating the disassembly and installation of the fixture and the parts mounted on it, ensuring the required coating thickness on both sides of the parts. The through holes on the wing plates primarily facilitate wastewater drainage during vacuuming and maintenance of the coating machine. The support columns mainly strengthen the structural strength of the connecting frame. Multiple automotive lamp components are fixed within the fixture.

[0007] Furthermore, the included angle between two adjacent winglets is 120°.

[0008] Furthermore, two opposing fixing plates are provided on both sides of the wing plate, and the support column is inserted between the two opposing fixing plates. Fixing screws are installed on the two fixing plates, and locking nuts are fitted onto the fixing screws. The support column is inserted between the two fixing plates, and the fixing screws on the two fixing plates can be tightened to clamp the support column between the two fixing plates, thereby achieving quick installation and disassembly of the support column. This allows for quick replacement of support columns of different lengths when dealing with aluminum plating machines of different heights, improving the adaptability of the device.

[0009] Furthermore, the tooling piece has a first insertion piece at the top and a second insertion piece at the bottom. Both the first and second insertion pieces have insertion holes for engaging with fixing screws. These insertion holes are formed by joining two round holes, one smaller at the top and one larger at the bottom. On the other hand, the fixing screw can be inserted into the insertion holes on the first and second insertion pieces to achieve quick assembly and disassembly of the tooling piece. The fixing screw is inserted into the larger insertion hole, then slides downwards and engages in the smaller insertion hole, and then, with the help of a locking nut, achieves quick assembly and disassembly of the tooling piece.

[0010] Furthermore, the tooling piece has a first insertion piece on the top and a second insertion piece on the bottom. The first insertion piece has an insertion hole that mates with a fixing screw. The insertion hole is formed by two round holes that are smaller at the top and larger at the bottom. The second insertion piece has a U-shaped groove on the bottom that mates with a fixing screw.

[0011] The second connector has a U-shaped groove instead of a connector hole, making it easier to assemble and disassemble the tooling piece.

[0012] The beneficial effects of this utility model are as follows: The utility model provides a coating fixture rotating frame device, which uses a fixture piece to be inserted into the coating fixture through a plug hole that is smaller at the top and larger at the bottom, so as to realize the quick assembly and disassembly of the fixture piece, thereby realizing the coating of car headlight covers of different specifications; when the fixture pieces are set on the coating fixture, the included angle between them is 120°, the operating space is large, it is easy to store and retrieve coating parts, and the production efficiency is high.

[0020] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] Example 1:

[0022] like Figure 1-4 As shown, this utility model discloses a rotating frame device for coating tooling, comprising two opposing support discs 2, each with a central rotating shaft 1 fixedly connected to it. A connecting frame is provided between the two support discs 2, and the connecting frame includes two opposing support plates 3. Each support plate 3 is composed of three wing plates 31, with adjacent wing plates 31 forming a V-shape and the included angle between adjacent wing plates 31 being 120°. A connecting hole 32, which mates with the central rotating shaft 1, is provided at the center of each support plate 3. A bolt 4, threadedly connected to the central rotating shaft 1, passes through the connecting hole 32. A through hole 33 is provided at the end of each wing plate 31 away from the connecting hole 32. Multiple support columns 5 are engaged between the two support plates 3, and a tooling piece 6 is inserted between the two wing plates 31 located in the same vertical direction.

[0023] The wing plate 31 has two oppositely arranged fixing plates 34 on both sides. The support column 5 is inserted between the two oppositely arranged fixing plates 34. Fixing screws 7 are passed through the two fixing plates 34, and locking nuts 8 are fitted on the fixing screws 7.

[0024] The tooling piece 6 has a first insertion piece 61 at the top and a second insertion piece 62 at the bottom. Both the first insertion piece 61 and the second insertion piece 62 have insertion holes 63 that cooperate with the fixing screw 7. The insertion hole 63 is formed by splicing two round holes that are smaller at the top and larger at the bottom.

[0025] Working principle:

[0026] The support plate 3 consists of three wing plates 31, which make the included angle between the tooling pieces 6 mounted on the support plate 3 via the fixing plate 34 120°. The tooling pieces 6 are far apart from each other, providing a large operating space, which facilitates the storage and retrieval of parts from the tooling pieces 6. When replacing the tooling pieces 6, loosen the locking nut 8, lift the tooling piece 6 upward, and make the locking screw disengage from the small round hole of the insertion hole 63, which makes it easy to remove the tooling piece 6 from the connecting frame, and then replace it with a new batch of tooling pieces 6 to carry the parts for coating.

[0027] Example 2:

[0028] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the tooling piece 6 has a first insertion piece 61 at the top and a second insertion piece 62 at the bottom. The first insertion piece 61 has an insertion hole 63 that mates with the fixing screw 7. The insertion hole 63 is formed by splicing two round holes that are smaller at the top and larger at the bottom. The second insertion piece 62 has a U-shaped groove 64 at the bottom that mates with the fixing screw 7.
