When lathe and grinding machine are equipped with and rise by core fixture and use top working shaft-like workpiece, produce iron filings sometimes application jig centre bore and top on, the method of general removing is manually blown with air gun and hydraulic giant and pour cutting fluid, ensure clamp central hole and top clean, clamp central hole and top iron filings and other foul first will be removed before axle class positioning and clamping, shaft-like workpiece could be realized correctly locate, otherwise affect shaft-like workpiece endoporus and outer circles, the beating of end face.But increase manual steps with air gun and hydraulic giant, waste time and energy, and clamp central hole with top generally in tailstock tool direction, bad operation, does not clean up sometimes.
Summary of the invention
The object of this invention is to provide a kind of method of rise core fixture and clear bits of automatically clear bits, the automatic removing of realize rising core clamp central hole and top stickup iron filings.
Technical scheme of the present invention:
A kind of core fixture that rises of clear bits automatically, it comprises: pull bar, fixture connect dish, positioning core axle and tension mandrel, positioning core axle and fixture connect to coil and are connected, pull bar and fixture connect disk center's guide hole and are connected, the connectivity port of pull bar is connected with the link of tension mandrel, positioning core axle is connected with positioning sleeve and ringfeder, pull bar and tension mandrel are provided with air flue and communicate, pull bar venthole is connected with tension mandrel air admission hole, pull bar air admission hole is connected with air-blast device, and tension mandrel venthole is positioned on the position of tension mandrel and the top location of tailstock tool.
Preferred:
The central shaft of pull bar and tension mandrel is upwards provided with air flue, and tension mandrel venthole is positioned on tension mandrel central shaft.
The described dish that connects is provided with positioning sleeve the air flue be connected with pull bar, and the location of positioning sleeve is provided with venthole, and venthole is parallel with the central shaft of tension mandrel.
The core fixture that rises of the automatically clear bits described in utilization removes the method for iron filings automatically,
(1) shaft-like workpiece is put into and is risen by core fixture after positioning sleeve and ringfeder location, cylinder lever connecting rod tension tension mandrel, ringfeder tensioner shaft-like workpiece, tailstock tool is top when tension mandrel venthole position, start air-blast device, tension mandrel centre bore is blown, blowing-out tailstock tool top and tension mandrel centre bore surface iron filings, and then tailstock tool is top holds out against tension mandrel;
(2) after shaft-like workpiece processes, unclamp tailstock tool top, blow and again remove the surperficial iron filings of the top and tension mandrel centre bore of tailstock tool.
Pull bar of the present invention and mandrel design passage, communicate after assembling fixture.Connecing dish and positioning sleeve also can design some pores simultaneously, for propelling the price of some iron filings of cover grade fixture outer surface, achieving the automatic removing of rise core clamp central hole and top stickup iron filings.
