Description

Technical Field

[0001] The utility model relates to a positioning device, in particular to a positioning and leakage-proof assembly mechanism for manually assembled metal clips. Background Art

[0002] In the secondary processing and assembly of parts, we often encounter some clips (made of spring steel) that need to be installed on injection molded parts. Because the specifications of the clips are different, some are small in size, some are small in volume, some have different load capacities, and some need to be installed in multiple positions on an injection molded part. Correspondingly, the hole sizes and heights of the installation positions are also different.

[0003] The assembly process is mostly manual operation. Due to the various differences and multiple points of parts, it is difficult to control the stiffness when pinching the buckle with fingers during manual assembly. Some parts are small and the installation holes are blocked when picked up by fingers. The force cannot be consistent. Long-term pressing and stressing cause the operator's fingers to swell and ache, which prolongs the assembly cycle and reduces the efficiency. Even if the assembly is barely assembled and inserted, change points are likely to occur, which may easily cause incorrect verticality and offset when pressing into the injection molded part hole, resulting in poor assembly and the risk of missing assembly, which affects the reliability after installation. In addition, the assembly is time-consuming and laborious for workers and there is rework, etc., which makes it difficult to ensure processing efficiency and product quality. A positioning and anti-missing assembly mechanism for manually assembled metal clips is proposed. Utility Model Content

[0004] The main purpose of the utility model is to provide a positioning and leakage prevention mechanism for manually assembling a metal clip, so as to solve the problems in the related art that the rigidity is difficult to control when the fingers pinch the clip during manual assembly.

[0006] Furthermore, a lever cylinder is fixedly mounted on the surface of the product positioning portion, a pressing block is hinged on the surface of the lever cylinder, and the pressing block is located above the workpiece.

[0007] Furthermore, a mounting hole is provided inside the mounting portion, and the clip is movably inserted inside the mounting hole.

When the product positioning part matches the product, the technology to improve processing quality and accuracy can be realized. BRIEF DESCRIPTION OF THE DRAWINGS
