Description
Technical field
The utility model relates to machine tool fixture fields more particularly to a kind of machine for the positioning of semiaxis Double Tops point with top.
Background technique
Currently, the machine of semiaxis, which adds size (by taking pan portion as an example) general, carries out positioning clamping by the way of " one top of a folder ",
I.e. one end clamps Formation of Axle Shaft Spline using hydraulic three-jaw, and the other end holds out against centre bore using top positioning.And it is being installed and is being added
When the detection of work precision, generally detected using deflection instrument, benchmark be using the centre bore at semiaxis both ends as benchmaring,
Therefore add in machine with detection process, benchmark is not able to achieve unification, causes pan portion bounce universal bigger than normal.
Utility model content
To overcome existing machine to add the deficiencies of bigger than normal with semiaxis pan portion bounce caused by detection benchmark disunity, the utility model
The technical problem to be solved is that: a kind of machine top tip structure can be realized the positioning of semiaxis Double Tops point is provided.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
Machine for the positioning of semiaxis Double Tops point is with top, including positioning sleeve, support sleeve, top and pusher dog, the positioning sleeve
For the tubular structure of open rearward end, the support sleeve is slidably mounted in positioning sleeve, it is described it is top be mounted on positioning sleeve before
End middle part, pusher dog are slidably mounted on positioning sleeve front end, and the tail end of pusher dog contacts after passing through positioning sleeve with support sleeve.
Further, the pusher dog includes three and is centrosymmetrically arranged around top.
Further, location at spherical surface block is additionally provided between the support sleeve and positioning sleeve front end, the support sleeve and ball
Face locating piece passes through the cambered surface being mutually matched and sphere-contact, the pusher dog tail end are against location at spherical surface block front end.
Further, being equipped at least three springs between the location at spherical surface block and positioning sleeve.
Further, being equipped with card slot on the support sleeve and pusher dog, the positioning sleeve is equipped with anti-turn screw and inserts
In the card slot for entering support sleeve and pusher dog.
The beneficial effects of the utility model are: by one dedicated machine of design with top, double in the way of Double Tops point
Axis is positioned, and holds out against semiaxis pan portion with the pusher dog on top by machine to realize that the positioning of semiaxis clamps, so that semiaxis
Machine adduction detection benchmark realizes unification, to reduce pan portion bounce, improves the machining accuracy of semiaxis.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Label is 1- positioning sleeve in figure, and 2- support sleeve, 3- is top, 4- pusher dog, 5- location at spherical surface block, 6- spring, 7- half
Axis, 11- anti-turn screw, 12- anti-turn screw, 21- card slot, 41- card slot.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
As shown in Figure 1, the utility model includes positioning sleeve 1, support sleeve 2, top 3 and pusher dog 4, after the positioning sleeve 1 is
The tubular structure of end opening, the support sleeve 2 are slidably mounted in positioning sleeve 1, before described top 3 are mounted on positioning sleeve 1
End middle part, pusher dog 4 are slidably mounted on 1 front end of positioning sleeve, and the tail end of pusher dog 4 is contacted with support sleeve 2.The utility model makes
It is with process: is first mounted on the machine on machine tool chief axis with top, covers 2 tail portions using the hydraulic three-jaw clamping brace of lathe,
Then semiaxis 7 is put, the centre bore of 7 splined end of semiaxis is withstood using the locating centre on tailstock tool, using machine with top
Top 3 withstand the centre bore of 7 pan portion of semiaxis, finally move tailstock or machine tool chief axis, and pusher dog 4 is made to withstand on the end face of 7 pan portion of semiaxis
On, avoid the semiaxis 7 during machine adds from rotating, to realize that the Double Tops point positioning of semiaxis 7 clamps.
In order to guarantee that pusher dog 4 uniformly holds out against effect to 7 pan portion of semiaxis, the pusher dog 4 should be including three and in top 3
The heart is arranged symmetrically.The mountable non-slipping block in 4 front end of pusher dog improves the frictional force of pusher dog 4 and 7 pan portion of semiaxis.
Location at spherical surface block 5, the support sleeve 2 and location at spherical surface block are additionally provided between 1 front end of the support sleeve 2 and positioning sleeve
5 cambered surface and sphere-contact, 4 tail end of pusher dog by being mutually matched is against 5 front end of location at spherical surface block.Location at spherical surface is set
The purpose of block 5 be in order to further increase the precision that pusher dog 4 holds out against semiaxis pan portion, location at spherical surface block 5 can future self-supporting set
2 active force is evenly spread on three pusher dogs 4, to avoid causing semiaxis 7 to be oriented since 4 active force of pusher dog is different
The case where existing deviation.
Further, there is rigid collision during pusher dog 4 is held out against in order to prevent, in the location at spherical surface block 5 and determine
At least three springs 6 are equipped between position set 1.Three springs 6 are also centrosymmetric, and are arranged with three intervals of pusher dog 4.There is bullet
The buffer function of spring 6 can make pusher dog 4 achieve the effect that slowly to compress during holding out against semiaxis pan portion, avoid the occurrence of rigidity
It impacts and damages semiaxis or machine with top.
For convenient processing and manufacture, positioning sleeve 1, support sleeve 2, top 3 and pusher dog 4 generally can all be designed to cylinder, and
It needs to guarantee that positioning sleeve 1 and pusher dog 4 are not able to rotate after holding out against semiaxis pan portion, it is therefore desirable to design the similar structure type with sliding slot
It carries out circumferentially positioned.The utility model is the setting card slot 21,41 on support sleeve 2 and pusher dog 4 by the way of, in positioning sleeve 1
Upper setting anti-turn screw 11,12 is simultaneously inserted into the card slot 21,41 of support sleeve 2 and pusher dog 4.The length of card slot 21,41 should ensure that branch
Support set 2 and pusher dog 4 hold out against stroke, and width should be identical as the outer diameter of anti-turn screw 11,12.
The utility model with top, positions semiaxis in the way of Double Tops point by one dedicated machine of design, and
Semiaxis pan portion is held out against to realize that the positioning of semiaxis clamps with the pusher dog on top by machine, so that the machine adduction detection benchmark of semiaxis
It realizes unification, to reduce pan portion bounce, improves the machining accuracy of semiaxis.
