Description

A kind of positioner for pitching ear axial workpiece
Technical field
The utility model is related to a kind of fixture, more particularly to a kind of positioner for pitching ear axial workpiece.
Background technology
At hole position on processing fork ear, frequently with lathe process, but since the fork ear of fork ear axial workpiece is distributed in axis Both sides, when turning fork earhole position, can not use three-jaw or other universal fixture Set and Positionings, cause processing difficulties, machining accuracy compared with Difference and time-consuming, therefore it is necessary to design it is a kind of pitch ear axial workpiece positioner come solve fork ear orientation problem.
Utility model content
The technical issues of the utility model solves is to provide a kind of positioner for pitching ear axial workpiece, in solution The shortcomings that stating in background technology.
The technical issues of the utility model solves is realized using following technical scheme:
A kind of positioner for pitching ear axial workpiece, including taper main shaft and pedestal, the big end of taper main shaft is equipped with pedestal, The outer side center of pedestal is equipped with fork ear locating piece, and the outer upper of pedestal is equipped with height block, and lower part is equipped with clump weight, height block Outside is equipped with the fork trunnion locating piece with V-shaped groove, and the V-shaped groove for pitching trunnion locating piece positions fork trunnion by pressing plate, and fork ear is determined The centre of position block is equipped with location hole, and fork ear locating piece positions unilateral side fork ear through location hole attaching nut by bolt.
Further, the fork ear locating piece carries bolt and is connected with pedestal.
The utility model/advantageous effect of the invention is:
1. batch fork ear axial workpiece quick-clamping positioning turning can be realized, and ensure to pitch hole position concentricity on ear and hang down The design requirement directly spent.
2. the utility model is simple in structure, easy to assembly, it is easy to the operation and maintenance of worker, avoids subscription specific frock band Come the problem of taking considerable time, while reduce processing cost.

Specific embodiment
In order to which the technical means, creative features, achievable purpose and effectiveness for realizing the utility model are easy to understand, under Face combines and is specifically illustrating, and the utility model is expanded on further.
Embodiment 1, referring to Fig. 1 --- Fig. 9, a kind of positioner for pitching ear axial workpiece, including taper main shaft 1 and pedestal 3, pedestal, taper main shaft make of 30CrMnSiA materials, and are handled by heat treatment process, and the big end of taper main shaft 1 is equipped with base Seat 3, the outer side center of pedestal 3 are equipped with fork ear locating piece 5, and the outer upper of pedestal 3 is equipped with height block 7, and lower part is equipped with clump weight 4, the outside of height block 7 is equipped with the fork trunnion locating piece 8 with V-shaped groove, and the V-shaped groove of fork trunnion locating piece 8 is by pressing plate 9 to pitching ear Axis positions, and the centre of fork ear locating piece 5 is equipped with location hole, and fork ear locating piece 5 is right through location hole attaching nut 6 by bolt 2 Unilateral side fork ear positioning.
The fork ear locating piece 5 carries bolt and is connected with pedestal 3.
The fork ear axial workpiece for having opened first hole is mounted on fork ear locating piece 5 by the utility model, and fork ear locating piece 5 is located at 3 center of pedestal, fork ear axial workpiece upper end axis body are mounted on the height block 7 with V-shaped groove, which is located at pedestal 3 and pushes up End, clump weight 4 are located at 3 bottom of pedestal, and pedestal 3 is connected by taper main shaft 1 with machine tool chief axis set.
Hole position on the utility model processing fork ear is divided into two steps:
The hole position on the fork ear of one side is processed first, the unilateral fork ear of parts to be processed is leaned against on fork ear locating piece 5, alignment The main-shaft core of taper main shaft 1 positions unilateral side fork ear through location hole attaching nut 6 with bolt 2, then is positioned by pitching trunnion For the V-shaped groove and pressing plate 9 of block 8 to fork trunnion positioning, adjusting 4 weight of clump weight makes the uniform rotation under machine tool chief axis drive of pedestal 3, Vehicle goes out the whole hole on the lug of outside.Afterwards by fitting turnover, the hole position on vehicle opposite side fork ear, by the good lug hole of vehicle before It is placed on fork ear locating piece 5, is directed at main-shaft core, be equally to use 9 workpiece pressing of bolt 2 and pressing plate, it will be another by the rotation of pedestal 3 It makes hole position on the fork ear of one side.
The basic principle of the utility model and main feature and the advantages of the utility model has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description Simply illustrate the principle of the utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model is also Various changes and modifications are had, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed scope is defined by the appending claims and its equivalent thereof.
