Description
Technical field
The utility model belongs to field of machining, relates to a kind of gas inspection positioner, relates in particular to a kind of inspection of the gas for jig positioner.
background technology:
At present; in Machine Tool Fixture Design at home; in order to improve the automaticity of fixture and the reliability of clamping workpiece location; improve workpiece crudy; conventionally can design a kind of gas check at fixture locating surface; whether locate reliably automatically to detect workpiece, and automatically send signal and pass to electrical system.Although gas inspection positioner structure of the prior art is also uncomplicated, in test, accuracy is often difficult to reach requirement, and reliability is lower.In order better to solve jig gas inspection orientation problem, it is completely necessary developing a kind of Novel air inspection positioner.
Utility model content
The purpose of this utility model is to provide a kind of accuracy high, easy to use, can meet the gas inspection positioner of jig location, utilizes this device to become gas inspection navigation system by tandem compound, and can keep high reliability.
The technical solution of the utility model is: for the gas inspection positioner of jig, comprise valve body, spool, sealing ring, adjusting pad, detection contact, spring, screw plug; Spool is arranged in the valve opening of valve body, matched in clearance, and sealing ring is arranged in the groove on spool, spool can reciprocatingly slide in valve body hole, the conical surface of spool and the shoulder hole of valve body form conical surface seal by spring 6, and spool top is provided with adjusting pad, and adjusting pad top is provided with detection contact; Valve body lower portion is provided with screw plug.
On valve body, be provided with air inlet and gas outlet.
The utility model can reach following good effect after adopting technique scheme: one, and detecting reliability is high; Its two, detection range is wide, even larger from 0.015mm～1mm() flatness all can detect; Its three, standardization level is high, can make standard component, arbitrarily arrange.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model for the gas inspection positioner of jig.
Fig. 2 is the contour structures schematic diagram of the utility model for the gas inspection positioner of jig.
Fig. 3 is the system principle schematic diagram of the utility model for the gas inspection positioner of jig.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further: for the gas inspection positioner of jig, comprise valve body 1, spool 2, sealing ring 3, adjusting pad 4, detection contact 5, spring 6, screw plug 7; Spool 2 is arranged in the valve opening of valve body 1, and it is little matched in clearance, and sealing ring 3 is arranged in the groove on spool 2, ensures that it is air tight; Spool 2 can reciprocatingly slide in valve body 1 hole, and the shoulder hole of the conical surface of spool 2 and valve body 1 forms conical surface seal by spring 6, is provided with air inlet P and gas outlet T on valve body 1.Forming conical surface seal disconnects air inlet P and gas outlet T.Spool 2 tops are provided with adjusting pad 4, and adjusting pad 4 tops are provided with detection contact 5, are provided with air inlet P and gas outlet T on valve body 1, and valve body 1 bottom is provided with screw plug 7.
In the time that detection contact 5 is subject to the pressure of workpiece bottom, spool 2 moves, and conical surface seal is opened, and air inlet P and gas outlet T connect; During without External Force Acting, spool 2 cuts off inlet, outlet under spring-force driven dual.
While use, multiple (being generally three) gas check can be fixed on to positioning block of clamp A side by the screw via hole on valve body 1 on jig, adjusting pad 4 thickness are adjusted, make more than detection contact 5 exceeds positioning block of clamp A apparent height H.And gas check air inlet P is gone out with gas port T and be together in series, and the gas outlet T of last gas check meets pressure switch B.Form a complete jig gas check system, its system principle is shown in Fig. 3.
When workpiece is put on fixture locating surface and when clamped, workpiece bottom and positioning block of clamp A surface are adjacent to, and depress the detection contact 5 on gas calibrating bit location, and air inlet P, the gas outlet T of gas inspection positioner are opened; In the time that the inlet, outlet of connected all gas checks is all opened, compressed air-driven pressure switch B action, sends the reliable electric signal in location, thereby completes detection and localization.
On the contrary, do not open when the inlet, outlet that wherein has a gas inspection positioner, explanation has an anchor point not locate reliably, and at this moment pressure switch B can not move, and no signal is sent, and proves that workpiece location does not complete, and lathe can not start processing work.
