In the testing fields such as 3C electronics, automotive electronics, and industrial electronics, for a single testing machine, if multiple fully automatic tests are to be realized, its mechanism is often bulky and large, wasting too much space and cost for small test PCBA motherboards; PCBA boards (printed circuit boards) are widely used at present. It is the core of computers and embedded systems. Almost all electronic devices require the support of printed circuit boards. Therefore, printed circuit boards are products with the highest market share in the global electronic component products. In order to control and improve the production qualification rate. The detection work for controlling the quality stability is particularly important.

[0003] When 2 or more cylinders do synchronous movement, due to many reasons such as cylinder friction, pressure difference in multiple cylinders, unequal pipeline flow rates, and friction of mechanical components, it will cause phenomena such as unequal movement speed and uneven force, resulting in damage to the movement mechanism, damage to the test products, and seriously, the machine cannot work normally or even be scrapped. For each product change, corresponding equipment needs to be customized separately, increasing costs and occupying the warehouse. The air circuit connection between the fixture and the platform generally adopts a manual mode, which is time-consuming and laborious. In view of this technical problem, the present application proposes a synchronous mechanism clamping tooling for testing a small PCBA motherboard. Summary of the Utility Model
