Abstract
The utility model is related to a kind of mandrel positioning fixtures of processing wheel hub, including axial clamping jaw, axially position supporting block, pedestal, adjust core, floating disc, mandrel ring, dust cover, the adjusting core is fixed on pedestal, floating disc is sleeved on the upper end for adjusting core, the mandrel ring set is mounted in the upper end of floating disc, and mutually fixed by mandrel ring fastening bolt, the dust cover is fixed on the top of floating disc by cover board fastening bolt.The utility model blank wheel hub carries out axial floating in a manner of centre bore is contacted with orientational cone-shaped surface on the outside of mandrel ring using line in clamping during axial grip as radial positioning basis, blank wheel hub with floating disc, and completes radial self-centering action.Since blank wheel hub contacts positioning with the positioning method that locating core collar uses for line, blank wheel hub the problem of centre bore becomes interference fit with mandrel from clearance fit will not occurring after completing to process because of processing stress deformation.
Description
Technical field
The utility model is related to wheel hub processing equipment technical field more particularly to a kind of mandrel positioning of processing wheel hub
Fixture.
Background technology
In wheel hub process, the retrofit that outer surface is carried out to blank wheel hub is needed, it is therefore desirable to blank wheel
Hub is fixed, however since stress will produce slight deformation in Tutrning Process, so that the diameter of centre bore is become smaller.It is existing
Blank Hub fixture include pedestal and cylindrical type fixed central spindle, therefore blank wheel hub Set and Positioning is carried out using existing fixture
When, since in process, centre bore can become smaller, because can cause between fixed central spindle and centre bore, Interference contact is formed,
It is difficult to cause wheel hub to be detached from, it can also influence product and continue to position in the processing of next process.To solve the above-mentioned problems,
Mainly using reducing grip size or increase the product method of processing pre- allowance in industry, although this way can solve it is above-mentioned
Problem, but it is be easy to cause product orientation deviation or dimension deviation, influence product quality.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of processing wheel hub proposed is used
Mandrel positioning fixture.
To achieve the goals above, the utility model uses following technical solution：A kind of mandrel of processing wheel hub is fixed
Position fixture, including axial clamping jaw, axially position supporting block, pedestal, adjusting core, floating disc, mandrel ring, dust cover, it is described
It adjusts core to be fixed on pedestal by fastening bolt and holding bolt, during the floating disc is in cross, and upper/lower terminal is
Hollow structure, floating disc are sleeved on the upper end for adjusting core, and the caging bolt passes through floating disc to be fixed on the top for adjusting core, right
Restriction effect is played in the axial floating displacement of floating disc, and the mandrel ring set is mounted in the upper end of floating disc, and passes through mandrel ring
Fastening bolt is mutually fixed, and the dust cover is fixed on the top of floating disc by cover board fastening bolt.
Preferably, the top of the adjusting core is in " mountain " font, and spring is set on column therebetween.
Preferably, the mandrel ring, in cone, conical inclined-plane cone angle is 6 degree.
The utility model has the beneficial effects that：
Positioning core axle ring-shaped is designed as cone, blank wheel hub centre bore and mandrel ring in clamping by the utility model
Outside orientational cone-shaped surface is basic as radial positioning in a manner of being contacted using line, and blank wheel hub is during axial grip with floating disc
Axial floating is carried out, and completes radial self-centering action.The positioning method used with locating core collar due to blank wheel hub for
Line contact positioning, therefore blank wheel hub will not be matched with mandrel by gap after completing to process because centre bore occurs in processing stress deformation
Conjunction becomes the problem of interference fit.
Description of the drawings
Fig. 1 is the cross-sectional view of the utility model；
In figure：1-2-fastening bolt of pedestal, 3-adjusting core 4-floating disc, 5-spring, 6-mandrel ring 7-mandrel ring is tight
It is axial that 11-workpiece blank of fixing bolt 8-dust cover, 9-caging bolt, 10-cover board fastening bolt 12-holds bolt 13-tightly
Clamping jaw 14-axially position supporting block.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1, it is a kind of processing wheel hub mandrel positioning fixture, including axial clamping jaw 13, axially position supporting block 14,
Pedestal 1 adjusts core 3, floating disc 4, mandrel ring 6, dust cover 8, and the adjusting core 3 is by fastening bolt 2 and holds bolt tightly
12 are fixed on pedestal 1, and the top of the adjusting core 3 is in " mountain " font, and is set with spring 5 on column therebetween, institute
The floating disc 4 stated is in cross, and upper/lower terminal is hollow structure, and floating disc 4 is sleeved on the upper end for adjusting core 3, floating disc 4
Axial floating can be carried out on adjusting core 3, the caging bolt 9 passes through floating disc 4 to be fixed on the top for adjusting core 3, right
Restriction effect is played in the axial floating displacement of floating disc 4, and the mandrel ring 6 is sleeved on the upper end of floating disc 4, and passes through mandrel
7 phase of ring fastening bolt is fixed, and the mandrel ring 6 is 6 degree in cone, conical inclined-plane cone angle, may insure hair in this way
Linear contact between base wheel hub and mandrel ring 6, the dust cover 8 are fixed on floating disc 4 by cover board fastening bolt 10
Top, impurity and cutting fluid etc. can be prevented during use, which to enter in the utility model internal structure, influences the utility model
Service precision.
In use, by the installation to mandrel ring 6 of blank wheel hub 11, the outside of the centre bore and mandrel ring 6 of blank wheel hub 11
Taper positions contact of incline plane, and when axial clamping jaw 13 clamps blank wheel hub 11, blank wheel hub 11 is carried out at the same time axial floating with mandrel ring 6
Radial self-centering positioning is moved and completes, until blank wheel hub 11, which contacts axially position supporting block 14, completes clamping pinching action.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
