Description
Technical field
The present invention relates to a kind of secondary process frock of NC turret punch machine die shoe, particularly the processing tool of machining lower mold seat positioning keyway of numerically controlled capstan punch.
Background technology
On the NC turret punch machine one cover die shoe is one of vital part in the punch press, and the height of the keyway crudy of different directions, precision directly influences the serviceability and the service life of NC turret punch machine in its die shoe.It is the line patterning method that present domestic manufacturing firm generally adopts the processing method of die shoe keyway, and the crudy of keyway can not reach the performance requirement of punch press, is mainly that roughness is undesirable, the positioning accuracy of keyway is poor, with a kind of die shoe non-interchangeability of model.
Summary of the invention
The processing tool that the purpose of this invention is to provide a kind of machining lower mold seat positioning keyway of numerically controlled capstan punch makes the keyway positioning accuracy height of its processing.
The object of the present invention is achieved like this: the processing tool of machining lower mold seat positioning keyway of numerically controlled capstan punch, comprise the installation Connection Block that can be fixed on the broaching machine, Connection Block is installed is provided with discoidal positioning disk, the positioning disk center is provided with main locating hole, locating shaft perpendicular to positioning disk is installed in the main locating hole, be axially arranged with vertical on the locating shaft and run through the straight trough of locating shaft with positioning disk, positioning disk is provided with some workpiece locating holes, is provided with the position fixing handle that matches with the workpiece locating hole in the workpiece locating hole.
When the present invention works, utilize bolt will install on the workbench that Connection Block is connected broaching machine; Determine the locating shaft of different-diameter according to the size of circular hole on the die shoe to be processed, locating shaft is installed in the main locating hole on the positioning disk; Positioning disk is installed in company with locating shaft and installs on the Connection Block; The afterbody of broaching tool and the slide block of broaching machine are linked, and the blade of broaching tool is upward through straight trough, is placed in the straight trough of locating shaft; Die shoe to be processed is placed on the locating shaft, and give die shoe location to be processed through position fixing handle and workpiece locating hole, position fixing handle is passed the hole that sets in advance on the die shoe to be processed, again the workpiece locating hole on position fixing handle and the positioning disk is connected to a fixed, finish the preceding installation of broaching, at this moment, the direction of die shoe keyway is determined accurately; During broaching, broaching tool is under the driving of the oil cylinder of broaching machine, slide block, and the straight trough direction on the locating shaft is rectilinear motion up and down; Master cylinder moves downward, and drives broaching tool and broaches downwards, and broaching tool stops at extreme lower position, finishes the keyway of once broaching.Reorientate after die shoe turned an angle, the keyway of second direction of can broaching, the angle between two keyways of front and back determined by corresponding workpiece locating hole, repeats above-mentioned action and finishes keyway broaching on the different model die shoe same apertures.The size in the hole on die shoe changes, when broaching is in keyway on this hole site, because the position of broaching tool on broaching machine fixed.Therefore, should change the locating shaft that adapts this moment, repeats above-mentioned broaching method, can process the keyway on the different die shoes.The frock that adopts the present invention to describe is processed the positioning spline of NC turret punch machine die shoe, the keyway accurate positioning, and quality is good; Die shoe interchangeability with a kind of model is good; Process efficient and convenient efficient height, cost is low.
