Description

Technical Field

[0001] This utility model relates to the field of hanging fixture technology, specifically to a powder coating hanging fixture for tubular workpieces. Background Technology

[0002] Powder coating is a common decorative technique for metal surface treatment. Its working principle involves charging plastic powder using a high-voltage electrostatic device. Under the influence of the electric field, the coating is sprayed onto the surface of the workpiece, where the powder is evenly adsorbed, forming a powdery coating. After being baked at high temperature, the powdery coating flows and solidifies, melting the plastic particles into a dense final protective coating with varying effects, firmly adhering to the workpiece surface.

[0003] Existing curved workpieces (such as curved handles) require the use of hangers to suspend them during powder coating. However, existing workpieces are generally fixed to the hangers by clamping, and the coating cannot cover the clamping position during the powder coating process. Furthermore, the hanging beam only has a hanging position on one side, resulting in a small number of workpieces that can be hung, which reduces the efficiency of powder coating. Utility Model Content

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

[0005] To achieve the above objectives, the present invention provides the following technical solution: a powder coating fixture for tubular workpieces, comprising a hanging frame, wherein the hanging frame is provided with several hanging beams, the hanging beams are provided with two sets of hanging plates, a support base is provided between the two sets of hanging plates, the support base is provided with several hook components, a drive motor is provided on the side end of one set of hanging plates, and a rotating shaft is provided at the output end of the drive motor.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the hook assembly includes a gear rotatably connected to the rotating shaft, and a first rack and a second rack are meshed at the upper and lower positions of the gear. A first connecting arm and a second connecting arm are respectively provided at one end of the first rack and the second rack, and a first fixing rod is provided on both the first connecting arm and the second connecting arm.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the first fixed rod is provided with a sliding sleeve, and the bottom of the sliding sleeve is provided with a fixed seat.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the support base is provided with a number of second fixing rods.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the hanging bracket is provided with several hanging holes, and the hanging beam is inserted into the hanging holes.

[0010] The beneficial effects of this utility model are as follows: The hanger in this utility model is provided with multiple hanging beams. The number and position of the hanging beams can be flexibly adjusted according to actual needs. When spraying different numbers of curved tube-shaped workpieces, the hanging beams can be easily added or removed to change the layout of the hanger. At the same time, the hanging beams are provided with hook components. The output end of the hook components is inserted into the curved tube to fix the curved tube, so that the workpiece surface can be fully covered during spraying. Attached Figure Description

[0013] Figure 3 This is the utility model Figure 1 Enlarged diagram of point A in the middle. Detailed Implementation

[0014] 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.

[0015] See attached diagram. Figures 1 to 3 In this embodiment, a tubular workpiece powder coating fixture includes a hanger 1, a plurality of hanging beams 2 on the hanger 1, two sets of hanging plates 3 on the hanging beams 2, a support base 4 between the two sets of hanging plates 3, a plurality of hook components on the support base 4, a drive motor 30 on the side end of one set of hanging plates 3, and a rotating shaft 31 on the output end of the drive motor 30.

[0016] Furthermore, the hook assembly includes a gear 5 rotatably connected to the rotating shaft 31. A first rack 6 and a second rack 7 are meshed at the upper and lower positions of the gear 5. A first connecting arm 60 and a second connecting arm 70 are respectively provided at one end of the first rack 6 and the second rack 7. A first fixing rod 8 is provided on both the first connecting arm 60 and the second connecting arm 70.

[0017] Furthermore, a sliding sleeve 80 is provided on the first fixed rod 8, and a fixed seat 9 is provided at the bottom of the sliding sleeve 80.

[0018] Furthermore, the support base 4 is provided with several second fixing rods 40.

[0019] Furthermore, the bracket 1 is provided with several hanging holes 10, and the hanging beam 2 is inserted into the hanging holes 10.

[0020] It should be noted that in this embodiment, the support base 4 is provided with a side plate and a top plate to seal the hook assembly; the side plate is provided with several through holes to facilitate the extension and retraction of the first fixing rod 8.

[0021] Working principle: In use, the drive motor 30 drives the rotating shaft 31 to rotate, causing the gear 5 to rotate. The rotation of the gear 5 drives the first rack 6 and the second rack 7 to move. The movement of the first rack 6 and the second rack 7 drives the first connecting arm 60 and the second connecting arm 70 to move. This causes the first fixing rod 8 to move back and forth within the sliding sleeve 80 and extend out of the through hole. Then, the first fixing rod 8 and the second fixing rod 40 are inserted into the holes at the upper and lower ends of the bent tube-shaped workpiece, respectively, to fix the bent tube-shaped workpiece. Since workpieces can be hung on both sides of the support base 4, the number of workpieces that can be hung is increased, thereby improving the powder coating efficiency.

[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.
