Compared with prior art, the beneficial effects of the invention are as follows：Using electromechanical integration technology, by controlling the upper of cylinder
Lower motion, specific clamping switch control cylinder move downward, and trip switch control cylinder moves upwards, it is achieved thereby that cylinder
Drive and compress the purpose that cavity is compressed and unclamped with frock installation body realization；It is and accurate by magnetic valve and cylinder current limiter
The dynamics compressed is controlled, manual operation thrust is avoided and spends big or too small, cause sealing gasket and test tool rotation displacement
The problem of, at the same avoid cause for these reasons gas leak and the problem of influence test data.
Further, when clamping switch realizes that cylinder compresses downwards, guard grating is used to prevent staff from non-security
Position is placed or taken out test tool, improves the safety and reliability of operation.
Further, filter is used to purify air, prevents the impurity in air from causing to damage to test tool；Decompression
The further control pressure size of valve, speed is uniform when making compression, impact will not be produced to test tool, test tool will not move
It is dynamic, it is constant to compress dynamics.
Further, rubber blanket can make the sealing of test tool relatively reliable；The passage at sealing gasket center can
Ensure the requirement for compressing area and ventilating.
Further, the steam vent on frock installation body further increases the performance of exhaust.
Its is compact-sized for the device of the present invention, and control is tight, simple to operate, and speed is uniform during compression, and part is not produced
Impact, part will not move, and it is constant to compress dynamics, sealed reliable, and it is rapid to unclamp part, place, take out convenient part, safety,
Reliably, be loaded efficiency high, greatly alleviates the labor intensity of testing crew.Safeguard that simply manufacturing cost is low.
