Description

Technical Field

[0001] The utility model relates to the field of fixtures, in particular to a multi-hole vacuum fixture structure. Background Art

[0002] A fixture is a large category of tools for carpentry, ironwork, fitter, machinery, electronic control and some other handicrafts. It is mainly used as a tool to assist in controlling position or movement. Fixtures can be divided into three categories: process assembly fixtures, project test fixtures and circuit board test fixtures.

[0003] During the processing of the jig, an auxiliary device used to fix the processing object (workpiece) also plays an auxiliary function of guiding the processing, and is also called an auxiliary tool. For example, when a workpiece with a local protrusion on the back is placed on a flat machine tool and fixed with screws, it is difficult to fully press the workpiece. If you are not careful during processing, the screws may pierce obliquely. In this case, if a base jig that matches the shape of the back of the workpiece is used, the workpiece can be stably fixed, making it easier to operate. This is the basic concept of the jig.

[0004] In the existing technology, vacuum positioning jigs are usually used to achieve the effect of vacuum adsorption and fixation of special processing devices. When facing different devices, different positioning jigs need to be replaced. During the replacement process, the staff needs to clean the platform used to place the jig after processing, and clean the dirt attached to the platform due to processing, which affects the production efficiency. The purpose of the utility model is to solve the above defects and provide a multi-porous vacuum jig structure. Utility Model Content
