Description

Simple detection clamp for trial production of sample car

Technical Field

The utility model relates to a detection clamp, in particular to a simple detection clamp for trial production of a sample car.

Background

With the development of times, the period of new vehicle models of each whole factory to be listed is shorter and shorter. Similarly, the development cycle of the prototype vehicle is compressed once. The whole vehicle development is shortened to two months at present from one quarter two years ago, and the stamping development is also shortened to 40 days at present or less than 40 days from two months at two years ago. Therefore, in the sample vehicle trial production development process, the shortening of the development cycle of each link is of great significance. Therefore, the prototype industry prioritizes development cycle time, as well as development cost.

In the prototype manufacturing industry, the trial manufacturing is itself to verify the feasibility of the process or solution in mass production, and thus the requirements for the body dimensions are consistent with those of mass production. After some processes of the component are completed, the dimensions of the component need to be checked using a checking jig to confirm whether the design requirements are met.

The life validity period of the conventional detection clamp is generally 10 years, and the conventional detection clamp generally comprises a bottom plate and a detection clamp body arranged on the bottom plate, considering the mobility of the detection clamp, the convenience in operation and the reduction of the deformation of the detection clamp which can be generated in the subsequent use. The bottom plate is formed by welding a steel plate and channel steel or square steel. After the welding of the bottom plate is finished, welding stress exists, the stress release generally needs one week, and after the stress release is finished, the bottom plate is subjected to finish machining. The detection clamp body is generally processed by a machining center instead of wood. In order to ensure the processing precision, for a detection clamp with a relatively simple structure, a substitute wood is generally glued on a base plate after finish machining, and then the substitute wood is subjected to finish machining.

In the sample car trial-manufacturing industry, the general life cycle of the detection clamp is half a year, which is far shorter than the 10-year life cycle of the traditional detection clamp. Therefore, the structure of the detection clamp can be not as firm as the traditional detection clamp. Also, the one week period required for stress relief of the base plate requires time to compress or cancel the stress relief for development cycle reasons. However, the base plate which is not subjected to stress relief has an unacceptable large deformation amount in subsequent use. Accordingly, the prior art is yet to be improved and developed.
