The interconnecting piece of disassembly main body, the rotation of motor driven driving gear are connect, driving gear drives driven gear rotation, and driven gear drives
Transmission shaft rotation, transmission shaft drive elastic collet rotation, and disassembly main body is rotated together with elastic collet, dismantle the cone portion of main body
It is screwed in the blind hole being drilled with threaded shank, since disassembly main body is tapered, therefore the more can revolve the more tight, the rotation until being greater than broken bolt
Torque out, just can screw out the bolt that fractures and not defective work piece.
More preferably, the diameter of the driving gear is greater than the diameter of driven gear, increases revolving speed, it is ensured that can quickly smoothly
Back-out broken bolt.
More preferably, if the upper side of the crossbeam is provided with a spaced storage tube, storage tube is for placing difference
The disassembly main body of size, it is ensured that take convenient and efficient.
More preferably, the tubular structure that the storage tube is made of cylinder and cover, cylinder are made of using plastic material
Cylinder, the cylinder of plastic material is not only light-weight, but also avoid and collide with disassembly main body, causes to grind, scratch
Problem；Cover is hingedly connected on the side wall of cylinder upper end, is prevented in carrying process, disassembly main body fall, influence using.
More preferably, described sliding rail one end is fixedly connected with crossbeam, and the other end of sliding rail is provided with dismountable clamping bracket, really
Protecting the provision for disengagement can easily be fixed at the workpiece of broken-off screw to be removed, improve working efficiency, reduce hand labor
Intensity and can according to the demand of workpiece, replace clamping bracket.
Broken bolt of the invention is had the advantage that compared with prior art with provision for disengagement
(1), the present invention guarantee workpiece it is intact in the case where, can rapidly and efficiently completion broken bolt disassembly, drop simultaneously
Low labor intensity improves working efficiency；
(2), the present invention utilizes the different rotation directions of screw thread, screws in broken bolt by the threaded shank and cone portion of dismantling main body
It in blind hole, since disassembly main body is tapered, therefore the more can revolve the more tight, the back-out torque until being greater than broken bolt just can be fractureing
Bolt screw out and not defective work piece；
(3), the diameter that the diameter of driving gear is greater than driven gear increases revolving speed by gear drive, it is ensured that can be fast
Speed smoothly screws out broken bolt；
(4), elastic collet is used for connection disassembling main body and transmission shaft, it is ensured that installation and replacement disassembly main body is convenient and efficient, improves
Working efficiency；
(5), the present invention is moved down using the entirety that sliding rail realizes motor driver and dismantles main body, realizes that disassembly main body is suitable
Benefit screws in the blind hole of broken bolt, and then realizes the disassembly of broken bolt.
Therefore the present invention has the spies such as reasonable, simple, easy to process, small in size, the easy to use, multi-purpose content of structure of design
Point, thus, it has good value for applications.
