Description
Technical field
The utility model is related to lathe spare and accessory parts technical field, and in particular to a kind of top.
Background technology
Top is the commonly used aid of mechanical field, during machine tool processing workpiece, to ensure the precision of workpiece and coaxial
Degree, all can be installed in lathe tail end one it is top withstand workpiece, widely, it is indispensable in Vehicle Processing for top application
Few aid.In use, can be inserted top on lathe in corresponding taper hole so that top to be fixed on lathe, when not
Need again with when directly will in the top taper hole from lathe extract.
There is problems with prior art：1st, need to shake top when top extraction taper hole so that after top loosening
Row is extracted again, is very easy to damage top, is influenceed top service life；2nd, during machine tooling, due to the rotating speed of main shaft
Larger, rub sassafras for workpiece afterbody and top contact position, produces substantial amounts of heat, long-term in this way, can accelerate top abrasion,
The top service life of influence.
The content of the invention
The purpose of this utility model is to provide a kind of top, is not only convenient for it and is removed from lathe, additionally it is possible to slow down top
The heat that tip is produced with the friction of workpiece afterbody contact position.
To reach above-mentioned purpose, base case of the present utility model is as follows：
It is top, including top body, it is threaded with top body on rotation section, rotation section and is rotatably connected to footstock,
Top body passes through rotation section and footstock；Top body is the positioning end that can be inserted into lathe close to one end of footstock；Top body
One end away from footstock is center point；Provided with the blowning installation that can be blown to center point in top body；Footstock is provided with spacing
Mouthful, provided with that can limit the spacing fast of rotation section displacement at limited mouth, blowning installation is by limited block control.
During using above-mentioned technical proposal, positioning end is inserted in the corresponding taper hole of lathe so that top body is fixed, so
Back centre end withstands workpiece and workpiece is processed, and after a period of time is processed, promotes limited block so that blowning installation pair
Center point is blown, and slows down workpiece afterbody and top contact position because of the amount of heat for the sassafras generation that rubs.When needs take from lathe
Under top body when, footstock and then rotary motion portion are held, because footstock props up lathe, so when the rotation of rotation section
Top body can gradually remove the bellmouth of lathe, now take out top body.
This programme produce beneficial effect be：
1st, after rotation section and footstock are set, when removing top body, footstock rotary motion portion again need to only be held, it is to avoid
Need to shake top situation when by top extraction taper hole and occur, extend top service life.In addition, footstock
Set, primarily to preventing rotation section from directly being contacted with lathe, it is to avoid lathe is worn and torn when rotary motion portion.
2nd, blowning installation can blow to center point, slow down workpiece afterbody and top contact position because of the big of sassafras generation of rubbing
Calorimetric amount, extends top service life.
Preferred scheme one：As the further optimization to base case, blowning installation is inflator, inflator be located at center point and
It is provided between rotation section, in inflator on piston, piston and is connected with inflating rod, one end of inflating rod through inflator is fixed with limited block
Connection；The other end of inflator is connected with and the air intake duct of ft connection and the gas blow pipe that can be blown to center point；Air intake duct and blow
Check valve is equipped with tracheae.
When needing to cool to center point, limited block is moved towards the direction of positioning end, inflator is evacuated,
Then limited block is moved towards the direction of center point again, air blowing cooling is carried out to center point.In addition, limited block can also be prevented
Rotation section at top body screw thread with departing from, when footstock and then rotary motion portion is held, and limited block all the time can only be in limit
The intraoral activity in position, so rotation section will not depart from top body all the time.
Preferred scheme two：As the further optimization to preferred scheme one, piston is connected with the end face of air intake duct with inflator
Between be provided with compression spring.
Be easy to inflator to carry out air-breathing automatically, by limited block towards center point direction movement after, compression spring can automatically by
Piston moves the air-breathing for realizing inflator towards positioning end, realizes and only promotes limited block once to can be realized as once blowing, reduces
Manually-operated step.
Preferred scheme three：As the further optimization to base case, footstock and rotation section are hollow cylindrical.
Very easy realizes the threaded connection of rotation section and top body, and top body can pound sliding in footstock
It is dynamic.
Preferred scheme four：As the further optimization to base case, ball is provided with center point.
So that ball is contacted with workpiece, the abrasion of center point is reduced.
Preferred scheme five：As the further optimization to base case or preferred scheme two, positioning end is No. 3 cones of Mohs
Spend, and the diameter of positioning end is gradually reduced away from the direction of footstock.
It is easy to the positioning of top body and lathe.
Brief description of the drawings
Fig. 1 is the top structural representation of the utility model.
Embodiment
The utility model is described in further detail below by embodiment：
Reference in Figure of description includes：It is top body 1, positioning end 11, center point 12, limited mouth 13, spacing
