Description

Support device for measuring automobile body}

The present invention relates to a support device for measuring an automobile body, and to a support device for measuring an automobile body that can stably support an automobile body for measuring the automobile body.

CMM (Co-ordinate Measurement Machine, 3-D Measuring Machine) refers to a device that measures the dimensions of various types of objects or parts such as automobile parts (hereinafter collectively referred to as objects) in three dimensions. Recently, CMM measurement has been widely used for precise measurement of objects.

For CMM measurement, the object must first be fixed on the measurement base according to its position and considering its inclination.

At this time, when performing CMM measurement on a simple object, for example, an object with a simple appearance such as a box shape, the object can be fixed without a special jig.

However, in the case of an object with a complex shape, it is difficult to fix the object on the measurement base without a suitable jig. Therefore, manufacturers producing automobile parts are using various types of jigs.

However, it is quite inconvenient and cumbersome to individually manufacture and prepare jigs suitable for each type of object.

In particular, the existing jig used by the company is not universal and is a jig that corresponds to each object one by one, so it is reported that the setting time takes several hours or more due to its structure.

As a result, in the case of the prior art, due to structural limitations, a corresponding jig must be individually manufactured for each object, which inevitably causes a large loss due to the production of the jig, and also raises the problem of requiring a lot of setting time. Therefore, there is a need to develop technology to solve this problem.
