Description
Technical field
The utility model relates to a kind of roller gear end face Vehicle Processing positioning fixture that is used for, and specifically, the utility model relates to a kind of cylinder external gear end face Vehicle Processing pitch circle positioning fixture.
Background technology
Cylinder external gear facing processing belongs to conventional Vehicle Processing, the cylinder external gear facing that is lower than 7 grades for accuracy class is processed, prior art generally with accurately machined other end as the axial location benchmark, be aided with soft pawl again and radially clamp the external gear teeth cylindrical.This kind vehicle clamper location structure is simple, and workpiece loading and unloading is easy, and turning is easy to process, and crudy can reach the design accuracy requirement fully.But, for precision be higher than the end face Vehicle Processing, particularly external toothing of 7 grades of vehicle transmission gears, in conjunction with the external gear end face Vehicle Processing of tooth and so on, do not reach the design accuracy requirement with the vehicle clamper processing of prior art.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, proposes a kind of rational in infrastructurely, and workpiece loading and unloading is easy, and cylinder external gear end face Vehicle Processing pitch circle positioning fixture is convenient in accurate positioning.
The utility model is achieved through the following technical solutions technical goal.
Cylinder external gear end face Vehicle Processing pitch circle positioning fixture, it comprise flange, in connect, limited block, clamp body, centring ring, Connection Block, gland, pillar, draw-bar seat and bolt.Described flange location also is connected the lathe spindle end, the draw-bar seat that through hole axial assemblage gap in flange middle part cooperates, and draw-bar seat connects the power pull bar that is built in the lathe spindle by bolt.Connect to disc element and end face of flange seam location in described and be connected, in connect the pillars of uniform 3～5 location, middle part, left side and connection.Described clamp body connects on the seam of left side in locating and being connected, and pillar axially passes from clamp body end face preformed hole.Described gland location and cylinder lever connecting rod seat left side, the linkage structure of formation locking fixture body.Described Connection Block location also is connected the conjuncted structure of formation on the pillar, and the centring ring of workpiece is located and be connected and installed in center, Connection Block left side.Its improvements are: described clamp body is axial pawl structure, its integrated disc portions is a thin walled elastic structure, uniform 3～5 rest shoes in left side, every rest shoe radially is provided with the location structure of being made up of taper pin and screw in the face of the excircle of workpiece position, and corresponding every the rest shoe of clamp body inwall is set up the limited block of restrained deformation amount.
In the said structure, the limited block right side and in connect between the left side preset clearance H value and allow the maximum flexibility deflection less than the clamp body thinner wall section.
The utility model compared with prior art has following good effect:
1, produce strain after the clamp body tension, make taper pin radially insert workpiece tooth portion thereupon and form engagement type location, this location benchmark is consistent with design basis, does not locate fiducial error;
2, taper pin radially clamps tooth portion, clamps not only fast but also reliable, and does not hinder facing processing;
3, motor-driven control clamp body strain is done workpiece locking or is loosened, and work-handling is easy to operate, the work efficiency height.
Description of drawings
Fig. 1 is the utility model cross-sectional view.
Fig. 2 is Fig. 1 left view.
The specific embodiment
The utility model is described in further detail with reference to the accompanying drawings below.
Cylinder external gear end face Vehicle Processing pitch circle positioning fixture shown in Figure 1, it comprise flange 1, in connect 2, limited block 3, clamp body 4, centring ring 5, Connection Block 6, gland 7, pillar 8, draw-bar seat 9 and bolt 10.Described flange 1 is the location standard, and flange 1 is with end face seam location and be connected the lathe spindle end, the draw-bar seat 9 that the axial assemblage gap of flange 1 middle part through hole cooperates, and draw-bar seat 9 connects the power pull bar that is built in the lathe spindle by bolt 10.In connect 2 for disc element and flange 1 end face seam location and is connected, connect uniform 3 of middle part, 2 left sides in the present embodiment and locate and the pillars 8 of connection.Clamp body 4 connects on the 2 left side seams in locating and being connected, and pillar 8 axially passes from clamp body 4 preformed holes.Gland 7 location and cylinder lever connecting rod seat 9 left sides, the linkage structure of formation locking fixture body 4.The centring ring 5 of workpiece is located and be connected and installed in center, Connection Block 6 left side.Clamp body 4 is the main components in the utility model, is axial pawl structure, and its integrated disc portions is a thin walled elastic structure.Uniform 3 rest shoes in clamp body 4 left sides in the present embodiment, every rest shoe radially is provided with the location structure of being made up of taper pin 4.2 and screw 4.1 in the face of the excircle of workpiece position.Corresponding every the rest shoe of clamp body 4 inwalls is set up the limited block 3 of restrained deformation amount.Limited block 3 right sides and in connect preset clearance between 2 left sides, this gap H value allows the maximum flexibility deflection less than clamp body 4 thinner wall section.
