In novel, the fixture it is simple and reasonable, clamp operation process is simple and practical, time saving and energy saving, Workpiece clamping excellent result,
To improve the quality of work pieces process and reduce the abrasion of process equipment.
Invention content
For processing part existing in the prior art and location hole and the big defect of holder axis coaxiality error, this reality
A kind of vertical wire pulling method fixture of inner sleeve spline is disclosed with novel, the utility model has installation simply, positioning accuracy height etc.
Advantage.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of vertical wire pulling method fixture of inner sleeve spline, including clamp body, the first radial positioning block and the second radial positioning
Block, it is characterised in that：Assembly flange seam allowance and locating flange seam allowance are provided on the clamp body；The first radial positioning block

It is both provided with part locating slot on face, the first radial positioning block and the second radial positioning block.
The first radial positioning block and the second radial positioning block are formed by the symmetrical cutting of Same Part.
The depth of parallelism of the part locating slot axis and fixture body axis is not more than 0.03, the part locating slot axis with
The verticality of part positioning surface axis is not more than 0.03.
Concentricity between the assembly flange seam allowance axis and locating flange seam allowance axis is not more than 0.02.
Compared with prior art, the utility model has the advantages that：
1, assembly flange seam allowance and locating flange seam allowance are provided on the clamp body of the utility model, the locating flange stops
Mouth has been bolted the first radial positioning block and the second radial positioning block by connection, and it is fixed that part is also vertically arranged on clamp body
It is both provided with part locating slot on plane, the first radial positioning block and the second radial positioning block；The utility model only needs to control
On clamp body on the concentricity of two flange seam allowances and radial positioning block part locating slot and fixture body axis concentricity
Control positioning accuracy of the radial positioning block to part；The utility model can either be reduced by using the mode that flange seam allowance connects
On the one hand connecting component between radial positioning block and clamp body simplifies the structure of fixture, improve mechanical stability, another
Aspect also achieves the assembly of the quick positioning between radial positioning block and clamp body, and then improves the positioning accurate of radial positioning block
Degree.
2, the first radial positioning block of the utility model is formed with the second radial positioning block by the symmetrical cutting of Same Part, and one
Aspect ensures size and the position degree requirement for meeting the first radial positioning block and the part locating slot on the second radial positioning block, carries
High assembly precision；On the other hand the difficulty of processing for reducing parts, saves production cost.
3, the part locating slot axis of the utility model and the depth of parallelism of fixture body axis are not more than 0.03, part locating slot
The verticality of axis and part positioning surface axis is not more than 0.03；Between assembly flange seam allowance axis and locating flange seam allowance axis
Concentricity be not more than 0.02, improve the positioning accuracy of part.
