The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

As shown in fig. 1-2, the present invention provides a universal profiling fixture comprising a base plate 1, a pneumatic slide 2, a mounting plate 3 and a plurality of profiling screws 4.

Pneumatic slip table 2 includes base, linear guide, slider, cylinder and cylinder buffer circuit. The base is arranged on the substrate. The linear guide rails are arranged on two sides of the base. The slide block is arranged on the linear guide rail and is connected with the mounting plate 3. The cylinder is arranged on the base and used for driving the sliding block to do linear reciprocating motion along the linear guide rail. And the air cylinder buffer air passage is connected with the air cylinder and is used for controlling the movement speed of the sliding table body.

The pneumatic sliding table 2 is a linear driving mechanism widely applied to the field of automation industry, and the accuracy of the pneumatic sliding table is effectively guaranteed and the stability of the mounting plate 3 in the moving process is guaranteed. The setting of cylinder buffering gas circuit has controlled the rate of motion of slip table body on linear guide for the motion of slider on the guide rail is more steady, accurate.

The mounting plate 3 is provided with a groove matched with the sliding block, the mounting plate is connected with the sliding block through the groove, and the mounting plate 3 is driven to move through the movement of the sliding block on the linear guide rail. The mounting plate 3 has a plurality ofly, connects through the mounting groove that sets up on the mounting panel between the different mounting panels 3.
