Background technology
Three-jaw round nut belongs to a kind of large-diameter and high-strength connector, and such a abnormity blank generally use alloy steel forging is broken into
Shape.Since there is position accuracy demand at three-jaw round nut center and radially overhanging three-jaw surface, along with bottom face forging have it is recessed
Convex alternate product identification so that bottom surface evenness is relatively poor, if blank three-jaw fluid-pressure clamping chuck, is difficult to
It is accurately positioned, it is necessary to realize positioning and clamping by alignment tool.Although such a operate letter to clamp the clamping pattern for substituting and positioning
Just, production is easily realized, but processing quality is extremely unstable, and also work efficiency is low.In short, three-jaw round nut uses prior art clamping only
It is adapted to single-piece or a small amount of production, it is impossible to meet requirements of mass production.
Utility model content
The utility model is mainly for the prior art using the end face positioning of commercially available three-jaw fluid-pressure chuck clamping three-jaw round nut
The problem of difficult, propose a kind of simple in structure, install convenient, accurate positioning, the three-jaw circle spiral shell that processing quality is stable, production efficiency is high
Female self-positioning vehicle clamper.
The utility model is achieved through the following technical solutions technical goal.
The self-positioning vehicle clamper of three-jaw round nut, it includes three-jaw fluid-pressure chuck, outer course mold insert, quarter butt, interior road position limiting pile, outer
Road position limiting pile, stock, interior road mold insert and stanchion.It is theed improvement is that：The three-jaw fluid-pressure chuck is between adjacent claw
On end face, interior road mold insert, outer course mold insert are sequentially connected from inside to outside, to back of work on the three-jaw fluid-pressure chuck end face of end face
Place is pre- to plant at least three axially extended stanchions.The stanchion is a kind of highly fine-tuning rigid bar, contour stanchion structure
Paired back of work axial positioning structure.The outer course mold insert and Nei Dao mold inserts are arc-shaped flat part, its center of circle and three-jaw
The oild chuck center of circle is consistent, and uniformly distributed at least three screw holes, any selection are first-class respectively in the plate face of outer course mold insert and Nei Dao mold inserts
Divide interior road mold insert, the outer course mold insert of installation, road position limiting pile, outer course position limiting pile in connection are matched on preset screw hole, it is rod-shaped
Interior road position limiting pile overhanging end is equipped with radial hole, and the quarter butt through radial hole is locked by the screw axial configured, and outer course is spacing
The default radial hole insertion stock of stake overhanging end, stock are locked by the screw axial configured.The quarter butt and stock are thin
Long straight-bar, quarter butt the inner abut against the overhanging pawl side of workpiece one, and stock the inner abuts against the same overhanging pawl radial end face of workpiece, thus
Form the unified mounting structure with selected pawl positioning of workpiece.
In said structure, the diameter of quarter butt and stock is equal, is the steel rod piece of 4~8mm.
The utility model compared with prior art, has the positive effect that：
1st, interior outer course mold insert and its supporting position limiting pile are added on the end face of three-jaw fluid-pressure chuck, it is simple in structure, make
Easily, the function of three-jaw fluid-pressure chuck and is not changed；
2nd, during clamping, the back side of workpiece directly avoids the male and fomale(M＆F) of preset identifications in back of work by stanchion axially position,
Easy to accomplish the workpiece of installation by real just energy axially position；
3rd, quarter butt and outer course position limiting pile configuration stock are configured on interior road position limiting pile, sets quarter butt respectively, stock stretches out length
Degree, is stablized easy to unified with a certain overhanging pawl location and installation of workpiece, this structure install convenient, alignment quality.

Embodiment
Below according to attached drawing and in conjunction with the embodiments, the utility model is described in further detail.
The self-positioning vehicle clamper of three-jaw round nut shown in Fig. 1, it include three-jaw fluid-pressure chuck 1, outer course mold insert 2, quarter butt 3,
Interior road position limiting pile 4, outer course position limiting pile 5, stock 6, interior road mold insert 7 and stanchion 8.The three-jaw fluid-pressure chuck 1 is commodity purchased, it
Structure carrier component as the utility model.The utility model is on the end face between 1 adjacent claw of three-jaw fluid-pressure chuck, by
Interior road mold insert 7, outer course mold insert 2 are sequentially connected from inside to outside.In addition, above 1 end face of three-jaw fluid-pressure chuck to 9 back side of workpiece at,
Pre- to plant three and arranged by decile and axially extended stanchion 8, which is a kind of highly fine-tuning rigid bar, this implementation
Example realizes liter or falling tone section using helical structure.The three stanchions height planted in advance on 1 end face of three-jaw fluid-pressure chuck is once set up, just
As axially position benchmark of 9 back side of workpiece before clamping, which directly avoids the male and fomale(M＆F) of preset identifications in back of work,
Easy to accomplish the workpiece of installation by real just energy axially position.The outer course mold insert 2 and Nei Dao mold inserts 7 are arc-shaped flat part,
Its center of circle is consistent with 1 center of circle of three-jaw fluid-pressure chuck.Three screw holes are evenly distributed with the plate face of outer course mold insert 2 and interior mold insert 7 respectively, arbitrarily
Interior road mold insert 7, the outer course mold insert 2 that a decile is installed are selected, road position limiting pile 4, outer course limit in pairing connection on preset screw hole
Position stake 5.Rod-shaped interior 4 overhanging end of road position limiting pile is equipped with φ 4mm radial hole.The quarter butt 3 of diameter 4mm runs through radial hole, position
Put and locked after setting up by the screw axial configured.5 overhanging end of outer course position limiting pile also is provided with φ 4mm radial hole, the length of diameter 4mm
Bar 6 runs through radial hole, is locked after position is set up by the screw axial configured.The quarter butt 3 and stock 6 are elongated straight
Bar, the present embodiment are manufactured with steel alloy material.Quarter butt 3 is inner in structure is used to abut against the overhanging pawl side of selected workpiece 9 one,
Stock 6 is inner to be used to abut against the selected overhanging pawl radial end face of workpiece 9 one, thus forms the unification of workpiece 9 to select pawl positioning
Mounting structure.
The utility model is directed to the architectural feature of workpiece 9, and location structure is added on commodity three-jaw fluid-pressure chuck 1 so that
The workpiece 9 of installation obtains reliable axially position before clamping and uniformly with the location and installation of selected pawl.Determine in this set
Clamped under the conditions of position, easy to operate, quick for installation, processing quality is stablized so that production efficiency improves more than three times.Therefore, originally
