Abstract
The invention discloses an electrode structure for forming symmetric holes once. The electrode structure comprises a box of a drilling machine, a driving device in the box and a feed shaft, the feed shaft is movably connected between an upper end plate and a lower end plate of the box, one extending end of the feed shaft is connected with the driving device to realize transmission, the other extending end of the feed shaft is fixedly connected with a shaft head, the upper end of a connecting sleeve concentric with the feed shaft is fixedly connected onto the lower end plate, and a spring electrode body is fixed onto an opening at the lower end of the connecting sleeve and positioned below the shaft head. Two symmetric holes or grooves are formed on the inner circumferential surface of a part, machining time is shortened, and production efficiency is greatly improved. The shape and the specification of the end of the feed shaft head are consistent with those of a push groove comprising two electrode guides, so that the tracks of two electrode tips sliding towards two sides are positioned on the same straight line, sliding distances are the same, and absolute symmetry of the positions of the holes formed on the inner circumferential surface of the part is ensured.
Description
Technical field
The present invention relates to Drilling operation equipment, be specifically related to a kind of electrode tip and feed mechanism thereof of one-shot forming symmetrical holes.
Background technology
In order to meet the symmetric relation of structure on part inner peripheral surface when general machining apparatus processes the structure such as symmetrical holes, groove on the inner peripheral surface of component of machine, the fixture toward wanting design specialized is gone in processing, if the size of hole to be processed or groove is also less or irregularly-shaped hole or groove, general machining apparatus then cannot process these structures due to the restriction of precision and cutter.
Along with spark technology is in the application in machined field, guarantee that the shape of hole or groove and precision have become comparatively easy, when by the symmetric relation also guaranteeing hole and groove when special fixture.But existing electric-spark drilling machine successively processes two symmetrical holes or groove, processes separately not only time-consuming at twice, and be difficult to ensure fixture, to add the relative position in man-hour at twice between electrode tip and workpiece three completely the same.Especially for the workpiece of some specific uses, it needs to complete drilling operation under water, workpiece needs to pull it the water surface after processing first hole, rotate special angle and put into fixing processing under water again, so not only complex operation causes working (machining) efficiency low repeatedly, also can increase mismachining tolerance, crudy be can not be guaranteed.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of electrode tip and feed mechanism thereof of one-shot forming symmetrical holes, can the symmetrical holes of one-shot forming surface of the work, guarantee the symmetric position of holes while ensureing holes dimensional accuracy, shorten process time and improve working (machining) efficiency.
The present invention is achieved through the following technical solutions:
The electrode structure of one-shot forming symmetrical holes, comprise the drive unit in the casing of drilling machine, casing, be movably connected in the feed shaft between the upper and lower end plate of described casing, one external part of described feed shaft and described drive unit connection for transmission, another external part of described feed shaft is fixedly connected with spindle nose; Be fixedly connected on bottom plate with the upper end of the concentric adapter sleeve arranged of described feed shaft, the opening of lower end is fixed with elastic press type electrode body, described elastic press type electrode body is positioned at the below of described spindle nose.
The further improvement project of the present invention is, the opening of described adapter sleeve is provided with the axis of guide, the two ends of the described axis of guide are fixed on the side plate that described adapter sleeve end face is provided with, described elastic press type electrode body is made up of two that are symmetrically distributed in described axis of guide both sides independent electrode body, fixed part and the described axis of guide of described electrode body main body are slidably connected, and the electrode tip of described electrode body is opposing is arranged on described electrode body lower end.
Further improvement of the present invention scheme is, is provided with spring between the fixed part of described electrode body main body and the side plate of respective side.
Further improvement of the present invention scheme is, to be the tapering extending to forward any be in the end of the described spindle nose taper shape of 45 °, described two electrode body lower surfaces are all fixed with electrode guide way, described two electrode guide waies are respectively equipped with arc notch with the correspondence position of described spindle nose end, and described two arc notch form one and push away groove with the taper of described spindle nose routing motion.
The present invention compared with prior art has the following advantages:
Spindle nose of the present invention does reciprocal stretching motion under drive unit drives, the each feeding of spindle nose just can give corresponding electrode guide way thrust of moving laterally, the electrode guide way being subject to this thrust drives connected electrode body to slide to the end of the axis of guide, now electrode tip energising is electric discharge punching on workpiece inner peripheral surface, then feed shaft slowly gets back to initial position under the drive of drive unit, and electrode body also gets back to initial position under the action of the spring gradually; So repeating to process can simultaneously two holes of shaping symmetry or groove on the inner peripheral surface of part, saves and substantially increases production efficiency process time.It is consistent that what spindle nose end and the two electrode guide waies of feeding in the present invention formed push away groove shape specification, therefore track from two electrode tips to two Slideslips on the same line, and the distance of sliding is identical, ensure that the absolute symmetry on workpiece inner peripheral surface forming hole position.
