Description

Technical Field

[0001] This utility model belongs to the field of pin manufacturing technology, and in particular relates to a pin spray painting hook. Background Technology

[0002] Currently, to improve efficiency and process quality, workpiece painting is carried out using assembly line operations. However, some long and narrow workpieces require hanging on rotatable hooks to ensure that both ends are painted evenly. While long and narrow workpieces typically have positioning holes that allow them to be hung on the painting hooks, pins are simply straight shafts without positioning holes. Therefore, they cannot be hung using this method and cannot be painted while suspended. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned technical problems by providing a pin-type paint spraying hook that offers convenient positioning, minimizes obstruction to ensure effective spraying, and improves space and production line utilization.

[0004] In view of this, the present invention provides a pin-type paint spray hook, comprising:

[0005] A fixed shaft component is used to position the pin in the outer circumferential direction. At least two fixed shaft components are arranged at intervals above and below each other. The two fixed shaft components are the same in shape but different in size. The two fixed shaft components are used to position two pins of different sizes respectively.

[0006] A connecting component for connecting two vertically positioned fixed shaft members.

[0007] In this technical solution, the absence of positioning holes on the pin shaft can be compensated by positioning the pin shaft in the outer circumferential direction, which makes positioning convenient. At the same time, the setting of two positioning parts with the same shape but different sizes can meet the positioning of pin shafts of different specifications. Furthermore, the two different specifications at the top and bottom have less obstruction, which ensures the coating effect and also improves space utilization and production line utilization.

[0008] Furthermore, the fixed shaft component includes a suspension part and a V-shaped clamping part, the V-shaped clamping part being used to hold the pin.

[0009] Furthermore, the fixed shaft component is formed by bending a round tube, and the fixed shaft component includes two V-shaped clamping parts located at both ends of the round tube, and the suspension part is located above the two V-shaped clamping parts.

[0010] In this technical solution, the fixed shaft part is divided into two specifications: large and small. The V-shaped clamping part has a larger opening, which is suitable for medium and large-sized pins, while the V-shaped clamping part has a smaller opening, which is suitable for medium and small-sized pins.

[0011] Furthermore, the V-shaped clamping portion is elastic.

[0012] In this technical solution, the V-shaped clamping part is made of elastic round tube steel, and the V-shaped opening can naturally hold the pin, without the need for manual adjustment.

[0013] Furthermore, the upper fixed shaft component is larger than the lower fixed shaft component.

[0014] Furthermore, the connection component includes:

[0015] A horizontal tube, the two ends of which are bent into hooks for hanging at the lowest point of the two V-shaped clamping parts of the fixed shaft component;

[0016] A circular ring, which is suspended on a horizontal tube, is used for the suspension part of the fixed shaft below to pass through and suspend.

[0017] In this technical solution, the suspension part of the ring and the fixed shaft component below can be connected by leaving a notch on the ring for the suspension part of the fixed shaft component to pass through, and then sealing the notch by welding after it is inserted.

[0018] Furthermore, the middle of the horizontal tube bends downwards, and the aforementioned ring is suspended at the lowest point of the bend.

[0019] Furthermore, the hook-shaped tops at both ends of the horizontal tube are provided with retaining blocks, which are used to increase frictional resistance at the lower end of the pin.

[0020] Furthermore, it also includes a hanging rod, which is set vertically with hooks at both ends. The hook at the upper end of the hanging rod is connected to the paint spray line, and the hook at the lower end of the hanging rod is connected to the suspension part of the uppermost fixed shaft component.

[0021] The beneficial effects of this utility model are:

[0022] 1. By positioning the pin on the outer periphery, the defect of no positioning hole on the pin can be made up, which is convenient for positioning. At the same time, the setting of two positioning parts with the same shape but different sizes can meet the positioning of pins of different specifications. Furthermore, the two different specifications at the top and bottom have less obstruction, which ensures the spraying effect and also improves space utilization and production line utilization. The whole has no bolts, clips or other connecting parts, and the suspension and clamping functions are achieved only by bending the round tube.

[0023] 2. Large and small fixed shaft components can be matched with pins of different diameters and lengths, eliminating the need for customized special tooling and reducing tooling costs by more than 60%. Attached Figure Description

[0043] The ring 7 is suspended on the horizontal tube 6 and is used for the suspension part 4 of the fixed shaft member 1 below to pass through and suspend.

[0044] The method of connecting the ring 7 and the suspension part 4 of the fixed shaft 1 below can be that a notch is left on the ring 7 for the suspension part 4 of the fixed shaft 1 to pass through, and then the notch is closed by welding after it is passed through.
