Individual screwed hole；Ring flange 12 is consistent with the profile of support block 11, and three through holes, position and 11 3 spiral shells of support block are uniformly made in end face
Pit is identical.
The bottom surface type face is consistent with product type face.
The head of screw rod 13 is T-shaped, and middle part is polished rod, and afterbody is screw thread, and afterbody top is handle.
The spreading component 2 is made up of circle wedge 21, jacking block 22, flexure strip 23, retainer ring 24, reset ring 25, screw 26；Circle
Wedge 21 assembles with screw rod 13T types head；Three jacking blocks 22 are uniformly fixed on the circumference of retainer ring 24 with flexure strip 23 by screw 26,
Retainer ring 24 is enclosed on the smooth bar part of screw rod 13, resets ring 25 and is enclosed on the flexure strip 23 fixed.
Circle wedge 21 is the Three-frustum-shaped with arc surface, and inside is stepped hole.
Jacking block 22 is L-type secter pat.
Beneficial effect：The present invention is made up of drawing assembly 1, the two parts of spreading component 2；For dismantling slight interference amount from inside
Axle sleeve coordinate.The present apparatus solves the problems, such as unbalance stress, quick-wear part during the dismounting of thin-walled interference fit shaft sleeve, substantially reduces
The loss percentages of detaching products.Axle sleeve is dismantled using the present apparatus, can be installed at inner hole of shaft sleeve, energy automatic capturing center, and
It is small volume, in light weight, be easy to use, can people's operation, reduce labor intensity, improve production efficiency.

Embodiment
The present invention is further described below in conjunction with the accompanying drawings：
Internal expansion type drawbench is made up of drawing assembly 1, the two parts of spreading component 2；Spreading component 2 is enclosed in drawing assembly 1
On screw rod 13, the circle internal stepped bore of wedge 21 assembles with screw rod 13T types head on spreading component 2, combines two components.Drawing
Component 1 is made up of support block 11, ring flange 12, screw rod 13, connecting rod 14, locking nut 15；Support block 11, the center of ring flange 12
Swivel nut is connected after being screwed with the tailing screw flight of screw rod 13 by connecting rod 14, and is locked with locking nut 15.Support block 11 be with
The tri-prismoid of arc surface, bottom surface is type face, consistent with product type face, and three screwed holes are uniformly made in the upper surface of support block 11；Method
Blue disk 12 is consistent with the profile of support block 11, and three through holes are uniformly made in end face, and 11 3 screwed holes in position and support block are identical.Spiral shell
The head of bar 13 is T-shaped, and middle part is polished rod, and afterbody is screw thread, and afterbody top is handle.Spreading component 2 by circle wedge 21, jacking block 22,
Flexure strip 23, retainer ring 24, reset ring 25, screw 26 form；Circle wedge 21 is the Three-frustum-shaped with arc surface, and inside is step
Hole, assembled with screw rod 13T types head；Jacking block is L-type secter pat, is connected with flexure strip, and three jacking blocks pass through screw 26 with flexure strip
Uniformly it is fixed on the circumference of retainer ring 24, retainer ring 24 is enclosed on the smooth bar part of screw rod 13, resets ring 25 and is enclosed on the elasticity fixed
On piece.
Device is slowly put into inner hole of shaft sleeve, by drawing assembly before use, spreading component is contraction state by the present apparatus
Support block be placed on the type face of interior axle and be bonded, check that the jacking block in spreading component should be at below axle sleeve overcoat end face.Then
Screw handle is rotated, screw rod drives circle wedge to rise, while makes jacking block radially spreading, reaches immediately below axle sleeve overcoat end face, by
In jacking block be radial motion, therefore can automatic capturing center.When jacking block is adjacent to overcoat lower surface, the upper surface of circle wedge disk
Jacking block lower surface is adjacent to simultaneously, drawbench starts stress.Screw handle is now firmly rotated, circle wedge and jacking block drive the outer of axle sleeve
Set motion upwards, until departing from interior axle, completes work.
