Specific embodiment
The utility model is further described with reference to Figure of description, so that those skilled in the art can be more
Understand the technical solution of the utility model well.
A kind of boring gang tool, as shown in Figure 1, including boring cutter body 3, screw rod 1, dress knife sliding block 5, leaning to mould 4, screw end
Lid 6 and boring cutter 8.Left section of the boring cutter body 3 is equipped with part endoporus along its axle center, sets that there are one through hole, institutes on the inner wall of endoporus
It states dress knife sliding block 5 to be mounted in through hole, boring cutter 8 is installed on dress knife sliding block 5, a retraction pin is additionally provided on dress knife sliding block 5
7, the mould 4 that leans to is located in the endoporus of boring cutter body, and the lower end for leaning to mould 4 is resisted against on dress knife sliding block 5, and retraction pin 7 is fastened on
In the sliding slot for leaning to 4 bottom of mould, the screw end cap 6 is mounted on the end of 3 left end of boring cutter body, the screw rod 1 one by bolt
End is extend into through screw end cap 6 in the endoporus of boring cutter body 3, is set in 1 end of screw rod for stretching into 3 endoporus of boring cutter body there are one being used for
Connection leans to the bulb of mould 4, and mould 4 is leaned in the endoporus of boring cutter body 3 in the axial direction by the control that rotates and reverse of screw rod 1
It to the right or is moved to the left, and then controls the stretching or retraction of boring cutter.When screw rod 1 rotates forward, it is right in the axial direction that promotion leans to mould 4
It moves, leans to mould 4 and promote dress knife sliding block 5 that can promote boring cutter 8 is protruding to achieve the purpose that boring cutter stretches out.Lean to the cunning of mould 4
Slot is variation compared with the outer diameter of boring cutter body 3 when axis direction is moved.When screw rod inverts, pulling leans to 4 edge of mould
When axis direction moves to left, the sliding slot for leaning to mould 4 is gradually distance from 3 outer diameter of boring cutter body of dress cutter, has just reached pulling dress knife sliding block 5
The purpose of retraction, boring cutter 8 and dress knife sliding block 5 are combined in one, and boring cutter 8 is also with regard in retraction boring cutter body body.The spiral shell of screw rod 1
There is distance of the enough length in order to left and right adjustment in line part.For nut there are two being set on screw rod 1 outside screw end cap 6
2, the nut 2 screws different positions on screw rod 1, the size that boring cutter 8 can be controlled to stretch out or retract, boring cutter body 3
Right section of outer circle is equipped with keyway, is easily installed and stablizes support key, the rigidity of increase long range boring, right section of the boring cutter body
End is equipped with the square thread being connected for the boring bar with horizontal boring machine.
The course of work
The big gradient deep hole workpiece 14 of overlength as shown in Figure 2, Workpiece length are 9.5 meters, and both ends aperture is small, median pore radius
Greatly, the aperture of left segment body 10 and right segment body 12 is 80mm, and the aperture of interlude 11 is 110mm.During boring, by the motor band of boring machine
Dynamic screw rod 1 rotates forward, and the promotion of screw rod 1 leans to mould 4 and moved to right in the axial direction in the endoporus of boring cutter body 3, leans to mould 4 and dress knife is promoted to slide
Block 5 makes to move outside boring cutter 8, and when moving on to the size for wanting 11 aperture of boring interlude outside boring cutters 8, two nuts 2 on screw rod 1 are revolved
Conjunction is adjacent in the end face of screw end cap 6, and two nuts 2 form an anchor point, that is, work of getting ready at this time.Invert screw rod
1 returns to initial position to initial position, boring cutter 8, which is connected on 14 meters of boring bars of horizontal boring machine, with
A diameter of guide support hole of the left segment body 10 of the big gradient deep hole workpiece 14 of overlength and the aperture of right segment body 12, apart from end face phase
Corresponding position is rotated forward by electric motor driven screw 1, you can boring cutter 8 is stretched out the size set and is carried out drawing boring processing.Draw boring processing
To after given size, 14 meters of boring bars of moving horizontal boring machine make boring gang tool return to initial position, then invert screw rod 1, make
Screw rod 1 moves to left, and pulling leans to mould 4 and moves to left, and skewed slot is under the action of retraction pin 7, filling knife sliding block 5 and bouncing back on mould 4 is leaned to, boring cutter
8 also just retract to initial position, and boring gang tool can be smoothly moved out the aperture of workpiece end, complete processing.
Above-described embodiment is only used for those skilled in the art understand that the technical solution of the utility model, and be not to its into
Row limitation, all any modification, improvement or equivalent substitutions made within the scope of protection of the utility model should be included in this
