Being connected by threaded engagement, the other end of pull bar 6 offers screwed hole b7, and protruding post a4, screwed hole b7 are arranged at pull bar 6
On central axis.
Clamping block 8 includes cylindrical block a8-2, and the end, one end of block a8-2 is provided with (cylindrical) protruding post b8-1, convex
The outer wall playing post b8-1 is provided with external screw thread, and protruding post b8-1 stretches into screwed hole b7 inside and is threaded connection with screwed hole b7,
The other end of block a8-2 is provided with round table-like block b8-3, and protruding post b8-1, block a8-2 and block b8-3 are all coaxially disposed (convex
Play post b8-1, block a8-2 and block b8-3 is three part-structures that composition clamps block 8, i.e. along latch segment 8 on latch segment 8
Protruding post b8-1, block a8-2 and block b8-3, owing to block b8-3 is round table-like, therefore block it is machined with successively on central axis
The diameter of body b8-3 one end end face is less than the diameter of block b8-3 other end end face, the end face of block b8-3 small diameter and block
A8-2 connects, the end face radius that block b8-3 and block a8-2 the connects radius more than block a8-2, the radius of protruding post b8-1
Radius less than block a8-2).
Chuck body 9 center offers one end of porose a10, transitional pore 11 and hole b13, hole a10 and chuck body 9 successively
End face is through, and hole b13 is through with the other end end face of chuck body 9, and hole a10 and transitional pore 11 are circular hole, and hole b13 is to be cut
Go to the vertex of a cone and the round table-like hole adapted with round table-like block b8-3 shape, the aperture of b13 one end, hole end face less than hole b13 another
The aperture of end end face, the end face of hole b13 smaller aperture due connects with transitional pore 11, the end face aperture that hole b13 connects with transitional pore 11
Aperture less than transitional pore 11 and the aperture more than hole a10, i.e. the aperture of hole a10 is less than the aperture of transitional pore 11, block a8-2
Being co-axially located at hole a10 internal (i.e. block a8-2 is coaxial with hole a10), block b8-3 is co-axially located at inside the b13 of hole, and fixture is originally
The opposite sides of body 9 further respectively has block 17, and block 17 is positioned at the end, one end and with one end of main shaft 5 even of chuck body 9
Connect.
The central angle of its mesopore b13 is 15 °～25 °, and best angle is 20 °, (owing to hole b13 is round table-like hole, therefore hole
The central angle of b13 represents 2 times of the bus of hole b13 and the centrage angle of hole b13, even hole b13 completion is become one
Coniform hole, the central angle of hole b13 or circular cone drift angle are 15 °～25 °), the central angle of the block b8-3 central angle than hole b13
Little 20 '～40 ' (owing to block b8-3 is round table-like, therefore the central angle of block b8-3 represents the bus of block b8-3 and block b8-
2 times of the centrage angle of 3, even become a cone-shaped structure block b8-3 completion, the central angle of block b8-3 or
Circular cone drift angle i.e. central angle little 20 '～40 ' than hole b13).
Wherein hole, location uniformly offers 4 or 8 along the circumference of chuck body 9, and hole, each location is centrally located at folder
On the same circumference of tool body 9 outer wall.
As shown in figs. 2 to 4, latch segment 15 is T-shaped structure, and the upper surface of latch segment 15 is convex structure, needs clamping
Time, the upper end arc surface of latch segment 15 with by weldering part 14 contact internal walls and will by weldering part 14 inwall hold out against, latch segment
The upper surface of 15 offers locating slot 16 (locating slot 16 is parallel and isometric with the camber line of latch segment 15 upper end arcwall face), respectively locks
Locating slot 16 on block 15 head and the tail successively are spliced to form cannelure, and the latch segment 15 being i.e. distributed in chuck body 9 is along same
Circle distribution, the head end of the locating slot 16 on the then next latch segment 15 of locating slot 16 end on a upper latch segment 15；
Locating slot 16 is provided with at least two, is parallel to each other and is spaced equal between each locating slot 16, each on each latch segment 15
Locating slot 16 is that a part for a cannelure, i.e. latch segment 15 are provided with several locating slot 16 and finally will form several annular
Groove, owing to the vertical block of only latch segment 15 stretches into inside hole, location, therefore, the vertical block knot of hole, location and latch segment 15
Structure adapts, and the arc surface on the lateral mass of latch segment 15 is positioned at above hole, location, during clamping weldment, and the horizontal stroke of latch segment 15
It is close on by the inwall welding part 14 to block.
Being socketed with elastic steel wire check ring 12 on cannelure, elastic steel wire check ring 12 is provided with opening and (is so easy to Elastic Steel
The installation and removal of silk back-up ring), the bottom of latch segment 15 is machined with inclined-plane, owing to block b8-3 is round table-like structure, therefore block
The outer wall of body b8-3 is arcwall face, and the inclined-plane bottom latch segment 15 and block b8-3 are linear contact lay, i.e. on block b8-3 wherein
Article one, the contact of incline plane bottom bus and latch segment 15, the inclined-plane bottom latch segment 15 is parallel with this bus makes latch segment 15 and block
The outer wall of body b8-3 can fit tightly.
The operation principle of the present invention a kind of large-scale part friction welding fixture is, when part is welded by needs,
Chuck body 9 coaxial sleeve is connected on by weldering part 14 internal (fixture that the present invention provides is directed to hollow sleeve pipe part),
Two blocks 17 are stuck in by the end of weldering part 14, when pressure oil enters the rod chamber of oil cylinder 1, and the piston rod 2 of oil cylinder 1 is to moving to left
Dynamic thus pull pull bar 6 and clamping block 8 to be moved to the left, block b8-3 is made by the interior fit on taper seat formed with latch segment 15
Latch segment 15 radially moves and is flared out, contact with by the endoporus of weldering part 14, along with the continuation of pressure increases by weldering zero
The be locked upper surface of block 15 of part 14 holds out against, complete before welding to the clamping by weldering part 14；Otherwise, after having welded
When needing fixture to withdraw from by weldering part 14, when pressure oil enters the rodless cavity of oil cylinder 1, and the piston rod 2 of oil cylinder 1 is to the right
Mobile thus pushing drawing rod 6 and clamping block 8 move right, and latch segment 15 is at deadweight and the bullet of the elastic steel traveler 12 with opening
Property power effect under to contract so that latch segment 15 with by weldering part 14 endoporus disengage so that by weldering part 14 be in
Releasing orientation, it is simple to dismantle by weldering part；The internal hole b13 offering taper of chuck body 9, is to ensure that in clamping by weldering zero
During part 14, oil cylinder 1 oil that is stressed is when increasing suddenly, and the displacement to the right of clamping block 8 is not too large, and latch segment 15 is radially
Displacement is the most little, from without being clamped by weldering part 14.
