Description

Technical Field

[0001] The utility model relates to the technical field of chemical electroplating treatment of workpieces, in particular to a square tube workpiece treatment hanger. Background Art

[0002] Due to their specialized nature, aviation parts manufacturing typically involves machining and surface anodizing processes. During anodizing, these parts are hung in batches on a bracket, where an applied current forms an oxide layer. However, batch processing of square tubes requires a long axial length, and due to electroplating requirements, the hanging or fixing position cannot be within the processing area. Therefore, it is difficult to stably hang square tubes on the bracket, creating difficulties in batch electroplating.

[0003] Therefore, the structure of the hanger needs to be further improved to meet the hanging requirements of square pipes. Utility Model Content

[0004] The purpose of the utility model is to provide a square tube workpiece processing hanger, which can realize the suspension of square tube fittings and facilitates quick disassembly and assembly.

[0005] In order to achieve the above-mentioned purpose of the utility model, the utility model provides a square tube workpiece processing hanger, including a rack, an upper rod, a lower rod, and a hook;

[0006] The hook is located at the top of the rack, and the upper rod and the lower rod are both connected to the rack;

[0007] The upper rod is provided with a plurality of upper clamping parts, which include an upper connecting rod, an upper triangular clamping block, and an elastic part. The upper triangular clamping block and the elastic part are respectively located at both ends of the upper connecting rod, and the end of the elastic part is connected to the upper rod;

[0008] The lower rod is provided with a plurality of lower clamping parts, the lower clamping parts including a lower connecting rod and a lower triangular clamping block, the lower triangular clamping block is located at the end of the lower connecting rod; the upper clamping parts are adapted to the arrangement positions of the lower clamping parts;

[0025] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, the square tube workpiece processing hanger of the present invention includes a frame 1, an upper rod 2, a lower rod 4, and a hook 6;

[0027] The hook 6 is located at the top of the rack 1, and the upper rod 2 and the lower rod 4 are both connected to the rack 1;

[0028] The upper rod 2 is arranged with several upper clamping parts 3, such as Figure 2 As shown, the upper clamping member 3 includes an upper connecting rod 31, an upper triangular clamping block 31, and an elastic member 33. The upper triangular clamping block 31 and the elastic member 33 are respectively located at both ends of the upper connecting rod 31, and the end of the elastic member 33 is connected to the upper rod 2;

[0029] The lower rod 4 is arranged with several lower clamping parts 5, such as Figure 3 As shown, the lower clamping member 5 includes a lower connecting rod 51 and a lower triangular clamping block 52, and the lower triangular clamping block 52 is located at the end of the lower connecting rod 51; the upper clamping member 3 is adapted to the setting position of the lower clamping member 5;

[0030] An adjustment slot 13 is provided on the side of the rack 1 , the end of the upper rod 2 is connected to the adjustment slot 13 via a first fastener 21 , and the end of the lower rod 4 is connected to the adjustment slot 13 via a second fastener 41 .

[0031] The height of the upper rod 2 can be adjusted using the first fastener 21, and the height of the lower rod 4 can be adjusted using the second fastener 41. The spacing between the upper and lower clamps 3 and 5 can be adjusted to accommodate different lengths of square tubes, thereby meeting different clamping requirements. The heights of the upper and lower clamps 3 and 5 can also be adjusted to adjust the fixed position of the square tubes according to the actual process requirements of the treatment tank.

[0032] like Figure 4 As shown, the two ends of the square tube 6 are buckled between the upper clamping piece 3 and the lower clamping piece 5, the upper triangular clamping block 31 is inserted into the top opening of the square tube 6, and the lower triangular clamping block 52 is inserted into the bottom opening of the square tube 6. Compared with conventional square clamping blocks, the upper triangular clamping block 31 and the lower triangular clamping block 52 are both triangular structures, which can be applied to square tubes of different diameters.

[0033] The surfaces of the upper triangular clamping block 31 and the lower triangular clamping block 52 are both provided with threads. When the upper triangular clamping block 31 and the lower triangular clamping block 52 are inserted into the pipe mouth, the thread structure can increase the friction force on the surfaces of the upper triangular clamping block 31 and the lower triangular clamping block 52, thereby improving the clamping effect.

[0034] The projections of the upper triangular block 31 and the lower triangular block 52 are perpendicular to each other. Figure 5-6As shown, the upper triangular clamping block 31 and the lower triangular clamping block 52 are both clamped at the diagonal position of the pipe mouth of the square tube 6, and the upper triangular clamping block 31 and the lower triangular clamping block 52 are perpendicular to each other in the cross-sectional projection position of the square tube 6. This upper and lower staggered clamping structure can more stably clamp the square tube 6 on the shelf 1 to prevent the square tube 6 from slipping out.

[0035] Several upper clamping members 3 are alternately arranged on both sides of the upper rod 2, and several lower clamping members 5 are alternately arranged on both sides of the lower rod 4. The upper clamping members 3 and the lower clamping members 5 correspond to each other in pairs, achieving simultaneous clamping on both sides of the rack 1. This can increase the number of square tubes 6 clamped, allowing more square tubes 6 to be processed in the same batch, improving production line efficiency. Moreover, compared to clamping on one side, the square tubes 6 on both sides can balance the rack 1, preventing uneven force and instability.

[0036] A reinforcing rib 12 is provided between the shelf 1 and the hook 6 to strengthen the connection strength of the shelf 1 to prevent the top of the shelf 1 from bending due to the heavy square tube after the material is stuck under the shelf 1.

[0037] Balance feet 11 are provided on both sides of the bottom of the rack 1 to facilitate the fixing of the rack 1 during the loading and unloading process.

[0038] The square tube workpiece processing hanger of the present utility model is suitable for batch fixing of square tubes to be processed. When clamping the material, the bottom of the square tube 6 is first clamped on the lower triangular clamping block 52, and then the top of the square tube 6 is clamped on the upper triangular clamping block 31. The elastic member 33 is elastic. After being squeezed by the square tube 6 below, the elastic member 33 is slightly lifted upward to provide space for the upper triangular clamping block 31 to clamp the material. After the material is clamped, the elastic member 33 is reset and the square tube 6 is clamped between the upper triangular clamping block 31 and the lower triangular clamping block 52. When it is necessary to remove the material, it is only necessary to lift the elastic member 33 to quickly remove the pipe fittings. The rack 1 with the square tubes 6 installed is connected to the copper busbar via the hook 6, and each square tube 6 is placed in the processing tank for processing.

[0039] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all within the scope defined by the claims of this application.
