Description

Technical Field

[0001] This utility model relates to the field of powder coating equipment technology, and specifically to a powder coating fixture for metal parts. Background Technology

[0002] Powder coating refers to the process of using an electrostatic generator to charge plastic powder, which can be applied to the powder coating of metal parts. It is a surface treatment method in which coating powder is sprayed onto parts. The coating powder on the surface of the workpiece is heated to a specified temperature and held at that temperature for a corresponding time to melt, flow, and solidify. During the process, the metal workpiece needs to be clamped and fixed before being heated and cured.

[0003] Currently, metal pipe powder coating uses external clamping, and most fixing devices can only fix one metal pipe, resulting in low powder coating efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a metal powder coating fixture to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a metal part powder coating fixture, including a bracket, a plurality of connecting rods on the bracket, a fixed column at one end of the connecting rods, a gear ring rotatably mounted on the fixed column, four gears arranged in a circumferential array on the outer periphery of the gear ring, a drive motor on one side of one gear, and a limiting mechanism on the gear.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the limiting mechanism includes a connecting shaft that is rotatably connected to the gear, and a turntable is fixedly provided on the top of the connecting shaft. The turntable has several arc-shaped grooves. The connecting shaft is also provided with a fixing sleeve, and the fixing sleeve and the connecting shaft can rotate relative to each other.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the outer periphery of the fixed sleeve is provided with a cross-shaped slide rail, the slide rail is provided with a slider, the top of the slider is provided with a limiting rod, the top of the limiting rod extends through an arc-shaped slide groove, and the limiting rod is slidably connected to the arc-shaped slide groove.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the top of the limiting rod is provided with a limiting block, which is a square plate structure or a semi-arc plate structure.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the bottom of the bracket is provided with casters.

[0010] The beneficial effects of this utility model are as follows: The clamp in this utility model includes a bracket, and the bracket is provided with several connecting rods. Each group of connecting rods has a limiting mechanism at its front end. The limiting mechanism has four limiting positions, which can clamp four metal parts at the same time, thus improving the efficiency of powder coating. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0016] See attached diagram. Figures 1 to 4 In this embodiment, a metal part powder coating fixture includes a bracket 1, a plurality of connecting rods 2 are provided on the bracket 1, a fixed post 3 is provided at one end of the connecting rod 2, a gear ring 4 is rotatably mounted on the fixed post 3, four gears 5 are arranged in a circumferential array on the outer periphery of the gear ring 4, a drive motor 6 is provided on one side of one gear 5, and a limiting mechanism is provided on the gear 5.

[0017] Furthermore, the limiting mechanism includes a connecting shaft 50 that is rotatably connected to the gear 5. A turntable 7 is fixedly mounted on the top of the connecting shaft 50, and a plurality of arc-shaped grooves 70 are provided on the turntable 7. A fixing sleeve 51 is also provided on the connecting shaft 50, and the fixing sleeve 51 and the connecting shaft 50 can rotate relative to each other.

[0018] Furthermore, the outer periphery of the fixed sleeve 51 is provided with a cross-shaped slide rail 52, the slide rail 52 is provided with a slider 53, the top of the slider 53 is provided with a limiting rod 54, the top of the limiting rod 54 extends through the arc-shaped slide groove 70, and the limiting rod 54 is slidably connected with the arc-shaped slide groove 70.

[0019] Furthermore, the top of the limiting rod 54 is provided with a limiting block 55, which is a square plate structure or a semi-arc plate structure.

[0020] Furthermore, casters are provided at the bottom of bracket 1.

[0021] Working principle: The drive motor 6 drives one of the gears 5 to rotate. The rotation of gear 5 drives the gear ring 4 to rotate. The rotation of gear ring 4 drives the other three gears to rotate. In turn, the gears drive the connecting shaft 50 to rotate, which in turn drives the turntable 7 to rotate. Since the turntable 7 is provided with an arc-shaped slide groove 70, as the turntable 7 rotates, the limiting rod 54 slides along the trajectory of the arc-shaped slide groove 70, so that the slider 53 at the bottom of the limiting rod 54 slides on the slide rail 52, thereby allowing the limiting block 55 to open or close, thus limiting the metal parts.

[0022] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
