Technical field

This utility model is related to clamping tool for machine work, and in particular to a kind of cydariform housing bearing seat hole group boring exclusive clamps Tool.

Background technology

The multiplex boring mode of bearing saddle bore for installing power transmission shaft on casing is processed, and bore is in most cases occur in groups , and be distributed according to certain mode.During bore hole, if the distribution of the shape of casing, bore is irregular, such as cydariform casing zero Part, then positioning, clamping, adjustment, processing of casing etc. are all relatively difficult, bore group working (machining) efficiency is low.

The content of the invention

The purpose of this utility model is：Design a kind of cydariform housing bearing seat hole group boring special fixture, simple structure, peace Dress is convenient, accurate positioning, clamps firmly, and adjustment is easy.

Technical solution of the present utility model is：The boring special fixture includes clamping fixture seat, clamp body and clamping body；Folder Set on the left side of tool seat in location hole, location hole and No. two straight pins and a spring are installed；Clamp body is in the form of annular discs, its right-hand member There are several dome-type location holes and several holes corresponding with the bearing saddle bore of cydariform casing being distributed on circumference on face The bigger through hole of size, is distributed a straight pin and rhombus pin on the left side of clamp body；Clamping body is by clamping seats and loose piece structure Into, two through holes and a screwed hole are opened on clamping seats, two through holes are used for connecting loose piece lifting bolt, and screwed hole is used for connecting Loose piece clamping screw, loose piece bottom is provided with the shaping contact face matched with cydariform casing, and two holes are opened on loose piece, hole top The aperture of aperture ratio bottom is little but bigger than the loose piece lifting bolt diameter of axle, and No. two spring housings penetrate together work on loose piece lifting bolt In the hole of block and through through hole on clamping seats and screw on nut；Clamping fixture seat is connected firmly by T-bolt with the workbench of boring machine, fixture Body right side is leaned against by stretching screw and clamping fixture seat to be close to, and stretching screw and clamp body, stretching screw and clamping fixture seat are all little Gap coordinates, and stretching screw had not only played rotation but also the effect of lifting pin, and clamp body rotates around stretching screw, when on clamp body When dome-type location hole is corresponding with No. two straight pins, a spring elongation allows No. two straight pins to be bound to dome-type location hole It is interior, make clamp body complete positioning by an end face, two pins, the locking nut clamp body screwed on stretching screw is clamped, Clamping seats are connected firmly by bolt with clamp body, are monolithically fabricated cydariform housing bearing seat hole group boring special fixture.

Wherein, two symmetrical pin-and-holes are provided with cydariform casing right side to be processed, its with clamp body on a cylinder Pin is corresponding with rhombus pin, it is ensured that the centre of gyration line of cydariform casing and the centrage of stretching screw overlap.

This utility model has advantages below：

（1）Stretching screw and clamp body, stretching screw and clamping fixture seat are all that small―gap suture coordinates, and have both played a part of rotation, Play a part of pin again.

（2）Loose piece can in a segment limit up and down, move left and right without dropping, carried out according to the size of cydariform casing A certain degree of regulation, absorbs grips error, makes clamping compacter.

（3）In the range of the clamping of clamp body, box sizes allow to change, with certain versatility.

（4）Whole clamp structure is simple, easy to operate, only needs clamped one time, can just process all bearing saddle bores, efficiency It is high.
