During the conical surface hole of centre frame is inserted to work piece axle housing one end among this technical scheme, retraining the location to axle housing shaft hole tip through the holding ring, guaranteeing that the shaft hole remains stable in boring machine processing in -process axiality, its machining precision can reach the technical requirement of regulation, has profitable technological effect and the practical value that is showing.
Description
Technical field
This utility model relates to a kind of boring machine for axle housing axis hole polish, belongs to machining apparatus technical field.
Background technology
Boring machine is the lathe carrying out boring with boring cutter pre-manufactured hole existing to workpiece.Generally, boring cutter rotates to be main motion, boring
The movement of cutter or workpiece is feed motion.It is mainly used in machining high-precision hole or one-time positioning completes the polish in multiple hole,
Additionally can be engaged in the processing of other machined surfaces relevant with hole polish.Boring machine also may be used at the different cutter of use and adnexa
Carrying out the operations such as drilling, milling, cutting, its machining accuracy and surface quality are all higher than drilling machine.But during actually used,
When processing axle housing axis hole, owing to axis hole is longer, and workpiece self is conical surface transition shape, and common boring machine is in the course of processing
In owing to being difficult to positioning shaft hole, cause axis hole axiality poor, the machining accuracy of workpiece does not reaches technology requirement all the time.
Summary of the invention
For solving problems of the prior art, this utility model provides a kind of boring for axle housing axis hole polish
Bed, concrete technical scheme is as follows:
A kind of boring machine for axle housing axis hole polish, including base, described base is symmetrically arranged with support, described
It is provided with boring bar between frame, described boring bar is provided with boring cutter, described base is fixedly installed centre frame, in described centre frame
Be symmetrically arranged with conical hole, bottom described conical hole, be provided with workpiece positioning ring, described boring bar run through centre frame conical hole and
Workpiece positioning ring.
As the improvement of technique scheme, between described centre frame and base, it is provided with cushion block, described centre frame and the end
Between Zuo, by running through, the clamping screw of cushion block is fixing to be connected.
As the improvement of technique scheme, on described support, the side near centre frame is provided with locating dowel.
As the improvement of technique scheme, described centre frame is provided above pressing plate.
In technique scheme, workpiece axle housing one end is inserted in the conical hole of centre frame, by locating ring to axle housing axis hole
End carries out constraint location, it is ensured that axis hole axiality during Boring machine processing keeps stable, and its machining accuracy can reach rule
Fixed technology requirement, has useful technique effect and significant practical value.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of boring machine for axle housing axis hole polish of this utility model；
Fig. 2 is the top view of a kind of boring machine for axle housing axis hole polish of this utility model.
Detailed description of the invention
As it is shown in figure 1, this utility model provides a kind of boring machine for axle housing axis hole polish, including base 10, institute
State and on base 10, be symmetrically arranged with support 11, be provided with boring bar 12 between described support 11, described boring bar 12 is provided with boring cutter
14, described base 10 is fixedly installed centre frame 20, in described centre frame 20, is symmetrically arranged with conical hole 21, described conical hole
Being provided with workpiece positioning ring 22 bottom 21, described boring bar 12 runs through conical hole 21 and the workpiece positioning ring 22 of centre frame 20.This skill
In art scheme, workpiece axle housing one end is inserted in the conical hole 21 of centre frame 20, is carried out axle housing axis hole end by locating ring 22
Constraint location, it is ensured that axis hole axiality during Boring machine processing keeps stable, and its machining accuracy can reach the technology of regulation
Requirement.
Further, between described centre frame 20 and base 10, be provided with cushion block 40, described centre frame 20 and base 10 it
Between by running through, the clamping screw 41 of cushion block 40 is fixing to be connected, this preferred version provides consolidating of a kind of centre frame 20 and base 10
Determining method, wherein cushion block 40 uses vulcanie to make, it is possible to play the effect of damping, buffering.
Further, on described support 11, the side near centre frame 20 is provided with locating dowel 13, and this locating dowel 13 is right
Centre frame 20 carries out cross spacing, it is to avoid during Boring machine processing, centre frame 20 rocks, and affects machining accuracy.
Further, as in figure 2 it is shown, described centre frame 20 is provided above pressing plate 30, this pressing plate 30 can be further
Back rest 20, prevents it from rocking during Boring machine processing.
Above embodiment of the present utility model has been described in detail, but described content be only of the present utility model preferably
Embodiment, it is impossible to be considered for limiting practical range of the present utility model, all impartial changes made according to this utility model scope
Change and improvement etc., within all should still belonging to this utility model covering scope.
