Slide unit test simulation real world needs a large amount of energy to come the accelerated test parts, system stores this energy as potential energy before the emulation collision, potential energy is stored with a large amount of pressurized air, and system is charged in the pneumatic linear actuator according to the gas that arranges storing before the test, pneumatic linear actuator emission slide unit.The pneumatic linear actuator of this testing laboratory design has three chambeies, is respectively emission cavity, air cushion chamber and cushion chamber.By system's setting and control pressurized air is filled with emission cavity during on-test, the air push lance of emission cavity then, lance promotes slide unit and produces motion.Therefore the lance of pneumatic linear actuator is subject to very large power in each test, exists the risk of damage.
Summary of the invention
The slide unit pneumatic linear actuator lance that the object of the present invention is to provide a kind of end for convenience detachly to keep in repair.
The solution of the present invention is as follows:
A kind of slide unit pneumatic linear actuator lance, comprise the guiding wheel hub, lance is terminal, described lance end links to each other with described guiding wheel hub, described guiding wheel hub top is provided with lance guide tip, elastomeric pad and rigid gasket successively, and described guiding wheel hub top also is provided with jump ring, and corresponding described jump ring is provided with groove on the chamber wall on described guiding wheel hub top, described jump ring cooperates described groove, described lance guide tip, rubber sheet gasket, rigid gasket is limited in the chamber on guiding wheel hub top.
Described lance guides the front opening of wheel hub, and the front end at described lance guiding end is identical with the front opening size of lance guiding wheel hub, and described lance guides the measure-alike of last rear end and described elastomeric pad.
The front end of described lance end protrudes, and the top of described bossing is provided with at least two threaded holes, and described guiding wheel hub rear portion correspondence is provided with at least two threaded holes, and described guiding wheel hub is connected via at least two bolts with described lance end.
Further, described lance end is provided with three threaded holes, and described three threaded holes evenly distribute along axis, and the aperture of described screwed hole of centre is greater than two threaded holes on both sides.
The fixed orifice of described bolt is counter sink.
Described lance guide tip is aluminum material.
Described elastomeric pad is rubber sheet gasket.
Beneficial effect of the present invention is as follows: the invention provides the lance that a kind of end can be for convenience detach, after guiding wheel hub top is put into rigid gasket, rubber sheet gasket and lance guide tip thereof successively, jump ring is clamped in the groove that is encased in lance guiding wheel hub by nose pliers (specific purpose tool), take out nose pliers and get final product unclamping, this moment jump ring locking rigid gasket, rubber sheet gasket and lance guide tip thereof, total installs.Damage if in test, find lance guide wheel hub area, can disassemble according to reverse order, change, can reduce the impact failure to slide unit simultaneously.
