Abstract
The invention discloses an adjustable spiral drill jig. The adjustable spiral drill jig comprises a base, a side supporting board, a rotary base and a drill jig assembly, wherein the rotary base is arranged on the side supporting board, the drill jig assembly is rotationally connected to the rotary base, a rotary shaft of the rotary base is in screw-thread fit with a joint of a locking handle, and a pressing board is arranged between the joint and the rotary base. The drill jig assembly comprises a rotating shaft, a rotary plate and a detachable drill jig body, wherein the rotating shaft is movably connected with the rotary base, and the rotary plate is fixedly connected with the rotating shaft. The drill jig body comprises a hemispherical die and a connection plate which is connected with the rotary plate, wherein the hemispherical die is provided with a plurality of guide holes which play a role in guiding when a workpiece is drilled, and the position, corresponding to the hemispherical die, of the rotary plate is provided with a boss used for pre-tightening the workpiece. The adjustable spiral drill jig is convenient to use, when the acetabulum file workpiece is drilled, the angle of the workpiece can be regulated only by rotating the rotary base so that the workpiece can keep perpendicular to a drill bit, and drilling accuracy is improved.
Description
Technical field
The present invention relates to mechanical clamp field, particularly a kind of adjustable spiral drill jig of use while carrying out high-precision borehole for double spherical work-piece.
Background technology
The manufacture of many equipment all can be used sphere boring, in prior art, sphere boring is manual mostly, the reamer for hip arthroplasty,acetabulum of medical instruments field for example, a kind of hemispheric stainless steel metal goods, on the sphere of reamer for hip arthroplasty,acetabulum, be provided with a plurality of holes, during boring, drill bit must just can be guaranteed the positional precision in each hole along hemispherical diametric(al), in use, these holes are as cutting edge, the downright bad part of patient's hipbone is cut, so the required precision for boring is very high, if drill bit and hemisphere face out of plumb during boring, just cannot guarantee that the hole getting out is along hemispherical diametric(al), during use, can cause damage to patient's hipbone, have a strong impact on quality and the efficiency of operation.And in boring procedure, prevent that workpiece from deforming, so the difficulty of processing is larger, at present, remains and complete by manual operations, manual efficiency is lower, the precision in each hole is also relatively difficult to guarantee, therefore, need to design and a kind ofly can improve drilling efficiency, can guarantee borehole accuracy again, the instrument that workpiece can not be out of shape simultaneously.
Summary of the invention
The object of the invention is to problem low for Manual drilling efficiency in the prior art described in background technology, low precision, a kind of adjustable spiral drill jig that can solve foregoing problems is provided.
The technical scheme that can realize goal of the invention of the present invention is as follows:
A kind of adjustable spiral drill jig, it comprises base, side support plate and be arranged on the swivel base on side support plate, be rotatably connected on the drill jig assembly on swivel base, the rotating shaft of swivel base coordinates with the joint screw thread of set lever, between joint and swivel base, be provided with pressing plate, described drill jig assembly comprises turning cylinder, rotating disk and dismountable drill jig, turning cylinder is flexibly connected with swivel base, rotating disk is fixedly connected with turning cylinder, drill jig comprises hemispherical mould and terminal pad, terminal pad is connected with rotating disk, the guide hole leading while being provided with a plurality of Workpiece boring on hemispherical mould, position corresponding with hemispherical mould on rotating disk is provided with the boss for top tight workpiece.
Described rotating disk and turning cylinder are bolted.
In order to facilitate the handling of workpiece, on described terminal pad, be provided with curved groove, curved groove dwindles gradually along dial rotation direction aperture, and on rotating disk, correspondence position is provided with tie down screw.
For the ease of the adjusting of swivel base, on described swivel base, be provided with the adjusting screw(rod) of restriction swivel base rotating speed, this adjusting screw(rod) is vertical with rotating shaft to be arranged.By adjusting screw(rod), can regulate the flexibility of swivel base when rotating, facilitate user that swivel base is adjusted to required angle, when adjusting screw(rod) is tightened, can to swivel base, play the effect of locking position, adjusting screw(rod) is more loose, and flexibility when swivel base rotates is better.
Adjustable spiral drill jig of the present invention is the particular manufacturing craft for the production of reamer for hip arthroplasty,acetabulum, and its creation has changed the full manual operations of existing mould.During use, first drill jig and rotating disk are opened, workpiece is placed on the boss of rotating disk, then drill jig is fixedly connected with rotating disk, now, boss is by workpiece pre-tightening, then, unclamp set lever, swivel base can freely be rotated, forward swivel base to suitable position, make to need on drill jig the guide hole at position of boring in vertical position, then by set lever, swivel base is positioned, then drill bit passes the guide hole on drill jig along vertical direction, workpiece is holed, because rotating disk can freely rotate, so when boring, guide hole can automatic calibration drill jig and the position of workpiece, guarantee the precision of boring, after having bored a hole, rotate rotating disk to next hole and arrive vertical position, after hole drill on same circumference is complete, again rotational lock handle, regulate swivel base, repeat above-mentioned process, until need porose whole completion of processing of processing, drill jig and rotating disk are opened, take out workpiece, complete the processing of workpiece.Known by above-mentioned hemispherical Workpiece boring process, adjustable spiral drill jig of the present invention has been realized mechanized operation, liberated most of labour, greatly improved operating efficiency, improved the precision of processing simultaneously, be easy to the handling of workpiece in mould, avoid workpiece to scratch in cargo handling process, guaranteed the crudy of workpiece.
