Abstract
The utility model is related to a kind of concentric special-shaped shaft member grinding frock, feature is：Frock is the cylindrical structural that outer surface is cylindrical surface, endoporus is location hole, the cross-sectional shape of location hole is consistent with the shape of the cross section of the special-shaped shaft part of concentric special-shaped shaft member, the center on cylindrical surface is overlapped with the geometric center of location hole, and radially at least there are one unicom cylindrical surfaces and the jackscrew mounting hole of location hole for system in frock.When this tool structure is for the cylindrical section periphery grinding of special-shaped shaft member with one heart, the special-shaped shaft part of abnormity shaft member is inserted into the location hole of frock with one heart, using the cylindrical surface concentric with location hole as positioning datum, so as to ensure that the concentricity of the cylindrical section of special-shaped shaft member and special-shaped shaft part with one heart, in addition, compared to existing processing, the section that is loaded need not be reserved again, so as to also improve workpiece grinding efficiency.
Description
Technical field
The utility model belongs to workpiece grinding frock, more particularly to a kind of concentric special-shaped shaft member grinding recruitment
Dress.
Background technology
It can be related to some special-shaped shaft member in automobile die accessory, such special-shaped shaft member is by circular shaft section and special-shaped shaft part structure
Into.The cross section of wherein special-shaped shaft member is regular symmetric shape, for example, the combining structure of single rectangular shape, two cuboids,
Combined shaped of cylinder and cuboid etc..The geometric center of the center of the circular shaft section of such special-shaped shaft member and special-shaped shaft part is in same
The heart is set, and concentricity requirement is higher.
Above-mentioned abnormity shaft member is after special-shaped shaft part machines, it usually needs grinding is carried out to circular shaft section, on the one hand
The dimensional accuracy of circular shaft section and surface smoothness is made to reach design requirement, on the other hand also to ensure special-shaped shaft part and cylindrical shaft
The concentricity requirement of section.For such special-shaped shaft member in grinding circular shaft section, best positioning method is with machined molding
Special-shaped shaft part is positioned, but is limited to special-shaped shaft part and is loaded on grinding machine difficulty, and the mode of generally use is：In special-shaped shaft part
The other end away from circular shaft section reserves one section of cylindrical section that is loaded, and after the completion of grinding, is cut off by the section that is loaded.
Using above-mentioned processing method, on the one hand to ensure the concentricity requirement of circular shaft section and special-shaped shaft part, difficulty of processing is high,
On the other hand there is also the low deficiencies of processing efficiency.
The content of the invention
The utility model provides a kind of raising workpiece grinding effect to solve technical problem present in known technology
Rate, and ensure the concentric special-shaped shaft member grinding frock of concentricity of workpiece.
The utility model is adopted the technical scheme that solve technical problem present in known technology：
A kind of concentric special-shaped shaft member grinding frock, it is characterised in that：Frock be outer surface be cylindrical surface, endoporus is
The cylindrical structural of location hole, the cross-sectional shape of location hole and the shape one of the cross section of the special-shaped shaft part of concentric special-shaped shaft member
It causes, the center on cylindrical surface is overlapped with the geometric center of location hole, and radially at least there are one unicom cylinders for system in frock
Face and the jackscrew mounting hole of location hole.
Further：The jackscrew mounting hole is arranged on the wide face of location hole.
Further：The location hole is in prolate cube shape.
Further：The first cuboid and the second cuboid that the location hole is overlapped by geometric center, which intersect, to be formed, the
The cross-section lengths of one cuboid are more than the cross-section lengths of the second cuboid, and the cross-sectional width of the first cuboid is less than second
The cross-sectional width of cuboid.
The utility model has the advantages and positive effects of：
Using this frock, when the circular shaft section to concentric special-shaped shaft member carries out grinding, by the different of concentric special-shaped shaft member
Shape shaft part is inserted into the location hole in frock, and the jackscrew by being tightened in jackscrew mounting hole carries out axial restraint, in this way,
Can frock positioning datum of the external cylindrical surface as grinding, due to the center on cylindrical surface and the geometric center of location hole
It overlaps, so as to ensure that the concentricity of the cylindrical section of special-shaped shaft member and special-shaped shaft part with one heart, in addition, abnormity shaft member need not with one heart
The section that is loaded is reserved again, in this way, compared with the prior art, the manufacturing procedure of the reserved section that is loaded and subsequent excision process are eliminated,
So as to also improve workpiece grinding efficiency.

Specific embodiment
For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates
Detailed description are as follows for attached drawing：
A kind of concentric special-shaped shaft member grinding frock, innovative point are：Frock is that outer surface is cylindrical surface 1, endoporus
For the cylindrical structural of location hole 2, the cross-sectional shape of location hole and the shape of the cross section of the special-shaped shaft part of concentric special-shaped shaft member
Shape is consistent, and the center on cylindrical surface is overlapped with the geometric center of location hole, and radially at least there are one unicom for system in frock
Cylindrical surface and the jackscrew mounting hole 3 of location hole.
In above-mentioned tool structure, the jackscrew mounting hole is further preferably arranged on the wide face of location hole.It in this way, can be square
Just process, and larger diameter can be selected in jackscrew mounting hole.
Below by taking two kinds of common concentric special-shaped shaft member as an example, the location hole of frock is described further：
The first tool structure：
The first tool structure is suitable for the first special-shaped shaft member 1 ' with one heart, the first concentric special-shaped shaft member is by cylindrical shaft
Section and prolate cube shaft part are formed, and corresponding to the concentric special-shaped shaft member, then the location hole in frock is prolate cube location hole, flat
The cross section of cuboid location hole is consistent with the cross section of the prolate cube shaft end of concentric special-shaped shaft member.
Second of tool structure：
Second of tool structure is suitable for second of special-shaped shaft member 2 ' with one heart, and second of concentric special-shaped shaft member is by cylindrical shaft
Section and intersected the special-shaped cuboid shaft part formed in a manner that geometric center overlaps by two cuboids and formed, corresponding to this with one heart
Special-shaped shaft member, then the first cuboid and the second cuboid that the location hole in frock is overlapped by geometric center, which intersect, to be formed, and first
The cross-section lengths of cuboid are more than the cross-section lengths of the second cuboid, and the cross-sectional width of the first cuboid is less than the second length
The cross-sectional width of cube.
Example preferably is applied the foregoing is merely the utility model, is not used for limiting the scope of the utility model.I.e.
The equivalent changes and modifications that all contents according to present utility model application the scope of the claims are done each falls within the technology model of the utility model
It encloses.
