At present, plastic clips are widely used to fix body plastic parts in the design of inspection tools for body plastic parts, and the design of clips is related to the recycling and cost saving of plastic clips. The snap of the original spring can only be opened to one side during disassembly, which limits the improvement of production efficiency. So, what are the specifications of car inspection fixture buckle? What plan is there to optimize the buckle design and make its function * * * trial?

Classification of automobile buckle

1. Classification by function

It can be divided into: fast wire seat buckle, threading nail buckle and general buckle. 

2. Classification by action site

Door panel buckle, roof buckle, bumper buckle, floor buckle, trunk buckle, sealing strip buckle, gutter buckle, interior trim panel buckle, exterior trim panel buckle, side beam buckle, chassis buckle, thermal insulation cotton buckle, seat buckle, handle buckle, strut buckle, protective plate buckle, etc.

With the improvement of people’s aesthetics, most enterprises will pay attention to the embedded connection or overall locking of parts in manufacturing, so as to make the products visually integrated. In order to achieve the above effects, the snap structure is also used more and more.

The buckle structure will be put into the inspection tool before using the product to check whether the fastener meets the standard. In the previous inspection mechanism, each part of the inspection tool is processed separately and then assembled together. In this method, there will be dislocation or inconsistent size of two matching parts, which requires re processing of parts, which not only seriously wastes the production time of the enterprise, but also the processed parts can not be repaired, resulting in a high scrap rate of parts.

Clip design scheme of automobile inspection tool:

1. Through the integrated processing of the snap cap assembly and the swivel arm assembly, after the processing is completed, the snap cap assembly and the swivel arm assembly are divided into two parts by wire cutting, that is, the snap cap assembly is divided into left snap cap and right snap cap, and the swivel arm assembly is divided into left swivel arm and right swivel arm. The mating parts processed in this way are fully matched, There will be no dislocation or inconsistent size. When the snap hole is changed, only the snap cap needs to be changed, and the swivel arm does not need to be changed again;

2. The purpose of reducing processing time, reducing production cost, reducing product scrap rate and improving processing efficiency and accuracy is achieved. In order to achieve the above purpose, the technical scheme of the utility model is as follows: a buckle mechanism for inspection tools, which is composed of a buckle cap assembly, a rotating arm assembly, a rotating shaft and a buckle seat;

3. The snap cap assembly is composed of a left snap cap and a right snap cap cut from the middle by a wire cutting machine;

4. The rotating arm assembly is composed of a left rotating arm and a right rotating arm cut from the middle by a wire cutting machine;

5. The left snap cap is fixedly connected to the top of the left rotating arm, the right snap cap is fixedly connected to the top of the right rotating arm, the left rotating arm and the right rotating arm are respectively located on both sides of the rotating shaft and movably connected with the rotating shaft, and the rotating shaft is fixed on the snap seat in an inverted T shape.

Due to the different requirements of different specifications of automobile inspection tools, the design of inspection tools should be optimized to improve the eating efficiency and detection accuracy of inspection tools, improve the use efficiency and detection accuracy of inspection tools, and reduce the development cost.
