AI Technical Summary
The existing lifting fixtures have poor versatility, requiring frequent replacement of fixtures according to different shapes and sizes of workpieces, which affects efficiency. Furthermore, manual loading and unloading is difficult and poses safety hazards. Insufficient hanging stability leads to uneven spraying, resulting in defects such as drips and orange peel, making it difficult to adapt to the needs of flexible production.
The design incorporates a support rod, a first hook, and a second hook. The first hook and the second hook are in surface contact, while the bottom of the second hook has an arc-shaped hook that forms a two-point contact with the workpiece. An opening is reserved for the lifting mechanism to facilitate quick loading and unloading. The support rod and the first hook are connected by adjustable bolts to accommodate different height requirements.
It enhances stability during the spraying process, reduces the frequency of fixture replacement, improves spraying uniformity and efficiency, reduces safety hazards of manual operation, and provides a foundation for the automation upgrade of spraying.

[0015] The embodiments of the application provide a workpiece hanging tool for a spraying assembly line, and solve the technical problems in the prior art that the hanger has poor universality, the hanger needs to be frequently replaced according to workpieces of different shapes and different sizes, the efficiency is affected, manual loading and unloading are difficult, safety hidden dangers exist, the workpiece is prone to uneven spraying, coating quality defects, the workpiece is prone to shaking due to insufficient hanging stability, flow hanging, orange peel and other defects are caused, and flexible production requirements are difficult to meet.
[0016] The technical solutions in the embodiments of the application are to solve the above problems, and the general idea is as follows:
[0017] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the drawings and specific embodiments of the specification.
[0018] A workpiece hanging tool for a spraying assembly line, as shown in Figure 1 and Figure 2 , comprising a carrier rod 1, a first hook 2 and a second hook 3; the carrier rod 1 is connected to the first hook 2 at the bottom end by a bolt; the second hook 3 is hung on the first hook 2, and the contact between the first hook 2 and the second hook 3 is a surface contact; the bottom end of the second hook 3 is provided with a hanging part; the hanging part at the bottom end of the second hook 3 is used to hang the workpiece; a reserved port 31 is opened on one side of the top end of the second hook 3; the reserved port 31 is used to cooperate with the lifting mechanism to perform loading and unloading operations.
[0019] The contact surface of the first hook 2 is an arc surface structure, and the contact surface of the second hook 3 is a groove structure matched with the plane of the first hook 2.
[0020] The hanging part of the second hook 3 is an arc hook, which is used to form two-point contact with the single lifting hole of the workpiece.
[0021] The carrier rod 1 and the first hook 2 are connected by an adjustable bolt to adapt to different hanging height requirements.
[0022] The bottom end of the carrier rod 1 is connected to the first hook 2 by a bolt, and the bolt connection can adjust the hanging height. The second hook 3 is hung on the first hook 2, and the contact surfaces of the two are a matching structure of an arc surface and a groove, forming a surface contact to enhance stability. The bottom end of the second hook 3 is provided with a symmetrical arc hook, which fixes the single lifting hole workpiece through two-point contact when hanging the workpiece. A reserved port 31 is opened on one side of the top end of the second hook 3, and the lifting mechanism can lift or lower the workpiece through the reserved port 31 to realize automatic loading and unloading.
[0023] Operation process:
[0024] Installation and height adjustment: connect the bottom end of the carrier rod 1 to the first hook 2 by a bolt, adjust the relative height between the carrier rod 1 and the first hook 2 by adjusting the fastening position of the bolt, and adapt to the assembly line hanging requirements.
[0025] Hook assembly: align the groove structure of the second hook 3 with the arc surface contact area of the first hook 2, hang it on the first hook 2, form a surface contact, and ensure the stability of the connection.
[0026] Workpiece hanging: align the single lifting hole of the workpiece with the symmetrical arc hook at the bottom end of the second hook 3, so that the two sides of the hook form two-point contact with the edge of the lifting hole, fix the workpiece and prevent it from rotating circumferentially.
[0027] Automatic loading and unloading: when the workpiece needs to be loaded and unloaded, the mechanical arm of the lifting mechanism is inserted through the reserved port 31 at the top end of the second lifting hook 3 to lift or lower the second lifting hook 3, thereby achieving rapid loading and unloading of the workpiece and avoiding safety risks of manual operation.
[0028] Spraying operation: after the workpiece is fixed, it is moved to the spraying area along the assembly line, and the face contact structure and the two-point hanging design ensure that the posture of the workpiece is stable, thereby avoiding coating defects caused by shaking during the spraying process.
[0029] Adaptive adjustment: if the workpiece type needs to be replaced or the assembly line height needs to be adjusted, the bolts of the bearing rod 1 and the first lifting hook 2 are loosened, and then they are adjusted and fastened again to adapt to different working conditions.
[0030] Due to the adoption of the bearing rod 1, the first lifting hook 2 and the second lifting hook 3, the contact area between the first lifting hook 2 and the second lifting hook 3 is a face contact, which increases the friction force, effectively avoids shaking or circumferential rotation caused by the movement of the wire body during the spraying process, ensures the uniformity of spraying, and reduces defects such as sagging and orange peel. The arc-shaped hook design of the second lifting hook 3 can adapt to workpieces of different sizes with a single lifting hole, reduce the frequency of replacing the hanger, and adapt to the flexible production requirements. The reserved port 31 cooperates with the lifting mechanism to realize rapid loading and unloading of the workpiece, improve the efficiency and reduce the safety hazards of manual operation, and provide a basis for the upgrading of spraying automation. The bolt connection structure of the bearing rod 1 and the first lifting hook 2 supports height adjustment, meets the diversified assembly line requirements.
