Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts detection, in particular to a three-axis detection mechanism for the appearance of automobile parts. Background Art

[0002] With the development of the times, three-coordinate detection has gone through more than half a century. Its emergence is a historical necessity for the development of industrialization. Three-coordinate detection is a relatively accurate and easy-to-operate detection instrument. Three-coordinate detection is also relatively widely used in automotive parts. During the production and assembly process of automobiles, each assembled component needs to be tested to ensure the product's qualification. This requires more precise detection of automobile parts.

[0003] However, there are some problems with the prior art: when inspecting the appearance of automobile parts, the parts are generally fixed and then inspected for appearance, or directly placed for appearance inspection, but this inspection can only perform appearance inspection on one side. If you want to inspect the bottom of the part, you need to disassemble the part, turn it over and re-fix it. The whole process is relatively cumbersome, which affects the efficiency of automobile parts inspection. At the same time, the fixed clamping style is single, and only one part can be clamped and inspected. When replacing different parts, the corresponding fixture needs to be replaced for clamping and fixing, which is easy to increase the company's production cost. Therefore, we propose a three-axis appearance inspection mechanism for automobile parts. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a three-axis detection mechanism for the appearance of automobile parts. By sliding two sets of fixing frames, the distance between the two sets of fixing frames is changed, which is convenient for clamping and fixing parts of different sizes. Then, the clamping claws are driven to rotate by the rotating assembly, so that the parts for appearance inspection can be rotated at an angle, which is convenient for all-round appearance inspection of the parts, thereby solving the problem that the appearance of parts can only be inspected on one side.
