Description
Technical field
The present invention relates to a kind of internal clamping device, more particularly to a kind of inside clamping device of sleeve pipe.
Background technology
Some set tubing workpiece, such as the inner ring outer ring of bearing can be all run into many auto parts machineries, is also had extensive
The bushing of application, bushing is a kind of wearing piece, in moving component, causes the abrasion of part because of long-term friction, works as axle
Have to renewal part when with the gap wear in hole to a certain extent, therefore from hardness is relatively low, the preferable material of wearability
Expect for axle sleeve or bushing, can so reduce the abrasion of axle and seat, when axle sleeve or liner wear are changed to a certain extent, this
Sample can save the cost because changing axle or seat.In order that bushing reduces abrasion as far as possible to axle and hole, it is necessary to bushing
Inside and outside carry out grinding so that the roughness of sleeve surface is smaller；When being ground in the outer surface to bushing, because folder
Tool is the periphery for clamping bushing, so being typically to be ground respectively from the both ends of bushing, hence in so that the grinding of bushing periphery
Efficiency is not high, and middle joint has the vestige of docking.
The content of the invention
The invention is intended to provide a kind of inside clamping device of sleeve pipe, to be clamped from the inside of sleeve pipe to sleeve pipe.
The inside clamping device of the base case sleeve pipe of the present invention, including pedestal, clamping jaw, top pressure screw rod；Also include top pressure
Steel ball；The pedestal is cylindric, and the lower end of pedestal has limit convex edge, and at least three cunnings are distributed with the radially uniform of pedestal
Groove, base central are provided with a screwed hole；The clamping jaw is slidably mounted in chute, and clamping jaw is provided with partially towards screw thread nose end
To in the cammed surface of top；A stopper slot is additionally provided with the upper plane of the clamping jaw, and limit is inserted into stop screw
In the groove of position, the stop screw is screwed on the pedestal；The top pressure screw rod is multi-diameter shaft, and the upper end of top pressure screw rod is big
End, lower end are small end, and the big end of top pressure screw rod is provided with the external screw thread closed with the corresponding threaded holes of the base central, top pressure spiral shell
Bar is screwed in the screwed hole of pedestal；Top pressure steel ball is arranged between the big end of the top pressure screw rod and the clamping jaw.
In this base case, top pressure screw rod can be rotated by welding handle in top pressure screw rod, or by spanner, turned
Dynamic top pressure screw rod, top pressure screw rod can move up and down relative to pedestal, and when top pressure screw rod moves down, top pressure screw rod can extrude top pressure steel
Ball, while extruding force is delivered in the cammed surface of clamping jaw by the meeting of top pressure steel ball, so that clamping jaw slides in and out, with this
From the inside of workpiece by Workpiece clamping.Rotating top pressure screw rod makes top pressure screw rod be moved up relative to pedestal, and top pressure steel ball is to folder
The extruding of pawl will be reduced gradually, finally unclamp workpiece.
In the present invention, the limit convex edge of pedestal lower end has the function that to workpiece, while limit convex edge also can use
In fixing this fixture.And clamping jaw is at least three, can make to the clamping force of workpiece evenly, so that the clamping to workpiece
It is more stable.The cooperation of limit sliding chutes and stop screw on clamping jaw can make this fixture when not clamping workpiece, and clamping jaw will not be from
Deviate from chute.The small end of top pressure screw rod has the function that to top pressure steel-ball limiting, if the end diameter of top pressure screw rod changes, just
Need to change the diameter of top pressure steel ball, so as to by the matching of the end diameter of top pressure screw rod and the diameter of top pressure steel ball come
The size of this fixture is controlled, so that the size of this fixture is not too large.When top pressure screw rod rotates, top pressure steel ball can also turn
It is dynamic, so that the abrasion between top pressure screw rod and top pressure steel ball, between top pressure steel ball and clamping jaw greatly reduces.
By this base case, workpiece can be clamped from the inside of workpiece, so that being ground to sleeve pipe
When can once carry out, and grinding efficiency can be improved.
Preferred scheme one, as the further optimization to base case, the top pressure screw rod upper end is provided with interior hexagonal；By
It is larger in the size of top pressure screw rod, so hexagonal is more suitable in setting.
Preferred scheme two, as the further optimization to base case, the section of the bare terminal end of the clamping jaw is to concave
Sunken V-shaped；The section of bare terminal end is the V-shaped to cave inward so that the bare terminal end of clamping jaw forms two edges of a knife, so that
The contact area of clamping jaw and workpiece is smaller, then the deformation of jaw surfaces is bigger, contacted with this clamping jaw with workpiece it is even closer, so as to
So that the frictional force increase between clamping jaw and workpiece, therefore more favorably prevent workpiece from rotating.
Preferred scheme three, as the further optimization to base case, extension spring is provided with the stopper slot of the clamping jaw, is drawn
The both ends of spring are hung on the stop screw and the spacing groove sidewall, set this extension spring that clamping jaw can be made to be pressed from both sides after unclamping workpiece
Pawl can be fully retracted in chute, so that it is more convenient to load workpiece next time.
Brief description of the drawings
Fig. 1 is the structural representation of the inside clamping device embodiment of sleeve pipe；
Fig. 2 is the part sectioned view of the inside clamping device embodiment of sleeve pipe.
Embodiment
Below by embodiment, the present invention is further detailed explanation：
Reference in Figure of description includes：Pedestal 1, clamping jaw 2, top pressure screw rod 3, stop screw 4, workpiece 5, top pressure
