[0002] Coating equipment is used with some coating fixtures to assist the parts in rotating and other movements during the coating process, so that the parts can be coated evenly.

[0003] In related technologies, when gear-like parts need to be coated, they need to be placed on a rotating fixture, and the coating is made uniform by the rotation of the fixture. When a large number of gears need to be coated, multiple racks are usually distributed around the circumference of the turntable, and the gears are placed on each rack.

[0004] However, during the rotation of the turntable, the sidewall of the workpiece facing the turntable axis is difficult to be coated, which affects the coating effect.

[0005] Therefore, how to solve the above problems is a problem that urgently needs to be solved by those skilled in the art.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0007] This disclosure provides at least one multi-column coating fixture and coating system.

[0008] In a first aspect, embodiments of this disclosure provide a multi-column coating fixture, comprising: a base; a plurality of star wheel mechanisms, all disposed on the base and arranged circumferentially, each star wheel mechanism comprising: a driven shaft, a mounting plate, and at least two driven teeth; wherein the driven shaft passes through the base, its lower end is provided with an input tooth, its upper end is provided with an output tooth, the mounting plate is sleeved on the upper part of the driven shaft, and the driven teeth are rotatably disposed on the mounting plate and mesh with the output teeth; a clamping tool holder, comprising: a plurality of clamping rods, each clamping rod being connected to a corresponding driven tooth; wherein each of the input teeth meshes with a fixed internal gear ring, and the base is adapted to rotate by rotating itself to cause the clamping rods to revolve around the sun while simultaneously rotating itself.

[0009] In one optional embodiment, the base is provided with a plurality of limiting posts; wherein the mounting plate has limiting holes; the limiting posts are adapted to be inserted into the corresponding limiting holes.

[0010] In one alternative embodiment, the tool holder further includes: a tool holder rod and several connecting assemblies; wherein the tool holder rod is vertically mounted on the base; and the connecting assemblies are adapted to connect the upper end of a corresponding clamping rod to the upper end of the tool holder rod.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.

[0026] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figure 1 As shown, at least one embodiment provides a multi-column coating fixture, including: a base 1, a tool holder 3, and a plurality of star wheel mechanisms 2.

[0028] Specifically, such as Figure 2 As shown, each star wheel mechanism 2 is mounted on the base 1 and is distributed in a circular pattern. The star wheel mechanism 2 includes a driven shaft 21, a mounting plate 22, and at least two driven teeth 23. The driven shaft 21 passes through the base 1 and can rotate but is axially limited. An input tooth 211 is fixedly provided at the lower end of the driven shaft 21, and an output tooth 212 is fixedly provided at the upper end of the driven shaft 21. The mounting plate 22 is sleeved on the upper part of the driven shaft 21, and at least two driven teeth 23 that mesh with the output teeth 212 are rotatably provided on it. That is, when the driven shaft 21 rotates, it drives each driven tooth 23 to rotate synchronously through the output teeth 212.

[0029] Specifically, the tool holder 3 is mounted on the base 1. The tool holder 3 includes several clamping rods 31, each clamping rod 31 being vertically mounted on the corresponding driven tooth 23 to follow the rotation of the driven tooth 23; wherein the clamping rod 31 is used to mount the parts that need to be coated.

[0030] In this embodiment, the input teeth 211 on each driven shaft 21 mesh with a fixed internal gear ring 4. That is, when the base 1 is subjected to force and rotates, the base 1 can drive the clamping rod 31 to revolve. At the same time, the clamping rod 31 rotates along with the input teeth 211, thereby making the coating of the parts on the clamping rod 31 more uniform.

[0031] like Figure 1 As shown, in some embodiments, a plurality of limiting posts 11 are provided on the base 1; wherein the mounting plate 22 is provided with limiting holes 221; the limiting posts 11 are adapted to be inserted into the corresponding limiting holes 221.

[0032] In this embodiment, since the mounting plate 22 needs to support two clamping rods 31, and the driven shaft 21 is located between the two clamping rods 31, the two clamping rods 31 are prone to shaking when loading parts. Therefore, this embodiment sets a limiting post 11 on the base 1, so that the limiting post 11 is inserted into the limiting hole 221 of the mounting plate 22, thereby preventing the mounting plate 22 from tilting and shaking when the force is uneven. The limiting post 11 is not fixedly connected to the mounting plate 22 in order to facilitate the disassembly of the tooling.

[0033] like Figure 1As shown, in some embodiments, the tool holder 3 further includes: a tool holder rod 32 and a plurality of connecting components 33; wherein the tool holder rod 32 is vertically disposed on the base 1; and the connecting components 33 are adapted to connect the upper end of the corresponding clamping rod 31 to the upper end of the tool holder rod 32.

[0034] In this embodiment, the tool holder rod 32 is the main rod with a relatively thick diameter. After the tool holder rod 32 is fixedly connected to the base 1, it is not easy to tilt or sway. The clamping rod 31 has a relatively thin diameter. After it is fully loaded with parts, it is easy to tilt or sway during revolution and rotation due to the heavy weight. Therefore, in this embodiment, the upper end of the clamping rod 31 is connected to the tool holder rod 32 to prevent the clamping rod 31 from tilting or swaying.

[0035] like Figure 1 As shown, in some embodiments, a connecting plate 34 is provided at the upper end of the tool holder 32; wherein the connecting assembly 33 is adapted to connect the upper end of the corresponding clamping rod 31 to the connecting plate 34 on the tool holder 32.

[0036] In this embodiment, the connecting plate 34 serves to increase the connecting area of ​​the tool holder rod 32.

[0037] like Figure 1 As shown, in some embodiments, the connecting assembly 33 includes a positioning plate 331 and a retaining plate 332; wherein the retaining plate 332 is connected to each clamping rod 31 in the corresponding star wheel mechanism 2; the positioning plate 331 is adapted to connect the retaining plate 332 to the connecting disk 34.

[0038] In this embodiment, a retaining plate 332 connects all the clamping rods 31 in a star wheel mechanism 2 together, and then the retaining plate 332 is connected to the connecting plate 34 by the positioning plate 331, thereby playing a fixing role.

[0039] like Figure 3 As shown, in some embodiments, a positioning cap 311 is fitted onto the upper end of the clamping rod 31; a retaining plate 332 is fitted onto the positioning cap 311.

[0040] In this embodiment, the clamping rod 31 needs to rotate during coating. Therefore, the retaining plate 332 is not fixedly connected to the clamping rod 31. Instead, a limiting hole is used to limit each clamping rod 31 to a retaining plate 332. The upper end of the clamping rod 31 is fitted with a positioning cap 311, which not only facilitates the installation of the retaining plate 332, but also reduces the rotational resistance between the clamping rod 31 and the retaining plate 332.

[0041] In some embodiments, the positioning cap 311 has a brim, so that the retaining plate 332 can be mounted on the positioning cap 311; in order to prevent the retaining plate 332 from coming loose, a limiting shaft clip can be used for limiting.

[0042] like Figure 4 As shown, in some embodiments, a first protective cover 222 is provided on the mounting plate 22; a second protective cover 12 is provided around the base 1.

[0043] In this embodiment, the tooling is also coated with material during the coating process. Therefore, this embodiment protects the gears of the tooling by setting a first protective cover 222 and a second protective cover 12 to prevent the gears from being affected by the coating material and thus prevent them from meshing and rotating.

[0044] In some embodiments, each driven tooth 23 is circumferentially evenly distributed, which allows the parts on each clamping rod 31 to be uniformly coated.

[0045] In some embodiments, the clamping rods 31 are evenly distributed around the circumference.

[0046] like Figure 5 As shown, at least one embodiment also provides a coating system, including: a coating chamber 5, in which a fixed internal gear ring 4 is disposed; a multi-column coating fixture, disposed in the coating chamber 5, such that each input tooth 211 meshes with the fixed internal gear ring 4; and a driver 6, connected to the outer surface of the coating chamber 5; wherein the driver 6 is adapted to extend into the coating chamber 5 and connect to a base 1 to drive the base 1 to rotate.

[0047] For the specific structure and implementation process of the multi-column coating fixture, please refer to the relevant discussion in the above embodiments, which will not be repeated here.

[0048] In this embodiment, after the multi-column coating fixture is installed into the coating chamber 5, its base 1 needs to be connected to the drive end of the driver 6 so that it can rotate by the drive of the driver 6; at the same time, each input tooth 211 on it meshes with the fixed internal gear ring 4, so that the input tooth 211 rotates when it revolves.

[0049] In some embodiments, optionally, the driver 6 is a servo motor.

[0050] In summary, this multi-column coating fixture and coating system, by having the input teeth 211 on each driven shaft 21 mesh with a fixed internal gear ring 4, allows the base 1 to rotate while simultaneously driving the clamping rods 31 to revolve around the central axis. Furthermore, to prevent the two clamping rods 31 on the mounting plate 22 from tilting or wobbling during parts loading and unloading, a limiting post 11 is provided on the base 1, which is inserted into the limiting hole 221 of the mounting plate 22, thereby preventing the mounting plate 22 from tilting or wobbling due to uneven force.

[0051] In this document, when it is said that the first component is located on the second component, this can mean that the first component can be directly formed on the second component, or that the third component can be inserted between the first component and the second component.

[0052] In this document, when an element or layer is referred to as being “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be an intermediate element or layer.

[0053] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0054] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the apparatus in use or operation.

[0055] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
