Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, the present invention includes 9, two vice bodies 6 of fuselage, shaft 12, axle sleeve 15 and clutch 7；The fuselage
Hydraulic motor 1 is installed, the front end of the rear end of the output axis connection shaft 12 of hydraulic motor 1, shaft 12 is equipped with coniform spiral on 9
Cutting head 4.As shown in figure 4, the coniform spiral cutting head 4 is a cone, it is machined with spirally in the side of cone
Cutting edge 41 is equipped with from the top-to-bottom of cone and helically cuts with chip-breaker 42, and spiral angle chip removal is more smooth.Spiral shell
Revolve the interconnecting piece 43 for being equipped with that section is hexagon at 4 rear end of cutting head；The front end of shaft 12 is equipped with the blind hole that section is hexagon；
The interconnecting piece 43 of spiral cutting head 4 and the blind hole of 12 front end of shaft cooperate.The shaft 12 is equipped with driven wheel of differential 13, from
Dynamic bevel gear 13 is engaged with drive bevel gear 14, and the shaft of drive bevel gear 14 stretches out fuselage, the shaft of drive bevel gear 14
End is equipped with handle 11.Torque input can carry out stepless speed regulation by hydraulic motor, can also the drive active conical tooth of crank handle 11
14 rotation of wheel, and then drive shaft 12 to rotate together by driven wheel of differential 13, in the case where manpower axially pushes, spiral cutting head 4
Carry out rotary expansion operation.
The rear portion of shaft 12 is equipped with screw thread；Two vice bodies 6 and fuselage are hinged, and two vice bodies 6 are symmetrical arranged about thread spindle.
The vice body 6 includes long-armed the II 3 of plier 5, long-armed the I 2 of triangle and triangle, and the upper and lower end face of plier 5 is fixed respectively
Long-armed the I 2 of a triangle are equipped with, the side of plier 5 is fixedly installed with long-armed the II 3 of triangle；Described long-armed I 2 pass through
Pull rod I 3 and axle sleeve are hinged, and long-armed II 2 is hinged by pull rod II 3 and axle sleeve, and pull rod I 2, pull rod II 3 and axle sleeve constitute one and put down
Row quadrangle.The width when cone bottom diameter of coniform spiral cutting head 4 is closed than two pliers 5 is big, and is located at 5 front of plier.Institute
5 side of plier stated is equipped with anti-slop serrations, preferably to contact fricton-tight expansion with by expansion, reduces and sliding generation occurs
A possibility that secondary injury.
The axle sleeve is sleeved on threaded portion in shaft 12, the clutch 7 include movable block 71, passage block 72 and
Isolating Switch 73, movable block 71 are spirally connected with threaded portion in shaft 12, and passage block 72 is sleeved in shaft 12, movable block 71 and push away
It moves the opposite end face of block 72 and is equipped with mutually matched groove and convex block, the Isolating Switch 73 is a column structure, fixed
It is mounted on the side of passage block 72, Isolating Switch 73 is inlaid in the L shape sliding slot 91 among fuselage 9.
When the invention works, firstly, the Isolating Switch 73 of clutch 7 is located at the bottom transverse groove of the L shape sliding slot 8 of fuselage 9
Interior, therefore, the movable block 71 of the clutch 7 in shaft 12 and passage block 72 are the states disengaged, and input torque links shaft 12,
Shaft 12 drive coniform spiral cutting head 4 outside plus input torque and axial force and under the action of self tapping power gradually (or impact)
It squeezes into narrow gap, as the narrow gap of the increase of hobbing depth is gradually biggish gap by cone expansion.It connects
, the Isolating Switch 73 of movable clutch 7 is pulled into the axial slot part into L shape sliding slot 8, input torque directly links shaft 12,
The movable block 71 for the clutch 7 being socketed in shaft 12 is combined with passage block 72, due to the Isolating Switch 7 of castellated movable clutch
It is stuck into the axial slot part in sliding slot 8, prevent the movable block 71 of clutch 7 is with shaft from rotating, and can only turn
Turning moment, i.e., be converted to axial displacement, drawn by pull rod I 2, pull rod II 3 by the lower axial movement of the threaded portion effect of axis 12
Dynamic vice body 6 moves, so that the plier 5 being fixed as one with vice body 6 is opened, the expansion of plier 5 is second of expansion.
When without input torque is added outside, drive bevel gear 14 can be driven to rotate by crank handle 11, and then by driven
Bevel gear 13 drives shaft 12 to rotate together, and in the case where manpower axially pushes, coniform spiral cutting head 4 carries out rotary expansion operation.
Working principle summary:
When needing to expand small gap, hydraulic motor 1 or crank handle 11 drive shaft 12 to rotate, under the promotion of manpower axial direction
4 Spiral cone head of spiral cutting head carries out rotary expansion operation.4 Spiral cone head of spiral cutting head screw into certain position, stretching pliers
It follows in taper hole, expander is next needed to carry out continuing to expand, 12 long axis of shaft continues to rotate, and covers on 12 long axis of shaft
Clutch 7 push axle sleeve movement, axle sleeve sliding block pulls two vice bodies 6 to move by pull rod I 2, pull rod II 3, of the invention at this time
Carry out expansion operation.Present invention support breaks obstructing objects, during vice body 6 opens, vice body 6 of the invention with by expansion
Angle vertical it is constant, vice body 6 of the invention can be vertical static with by expansion holding always, reduce expander slip can
Energy property, improves the security and stability of expander.
