Embodiment
Below in conjunction with the accompanying drawings and eccentric boring device described in the utility model is described in detail embodiment.
A kind of eccentric boring device described in the utility model, as shown in figure 1, including handle of a knife 1 and boring cutter 5；The handle of a knife 1
Lower end is provided with connecting hole；The side of the connecting hole sets fixing screws 7；Also include eccentric disc 3；The eccentric disc 3 is
One is cylindric；The core of the eccentric disc 3 is vertically installed with connecting shaft 6；A boring cutter is vertically arranged in the card of the eccentric disc 3
Hole；The boring cutter hole is a through hole, through the card of eccentric disc 3；The inwall in the side wall of the eccentric disc 3 and foregoing boring cutter hole it
Between be provided with two screwed holes, present lower vertical arrangement；Vertical arrangement can be such that two side-strengthened lock-screws 4 act on up and down
On boring cutter 5 in boring cutter hole, the fixation for boring cutter 5 is more firm；Side-strengthened lock-screw 4 is provided with the screwed hole；
The connecting shaft 6 of the eccentric disc 3 inserts connecting hole, and the connection of eccentric disc 3 and handle of a knife 1 is realized by fixing screws 7；The boring cutter
5 insertion boring cutter holes are connected by side-strengthened lock-screw 4 with eccentric disc 3.In the connecting shaft 6, boring cutter hole and screwed hole
Axis is in the same plane；By being positioned on same plane so that the side-strengthened locking screw being arranged in screwed hole
The screw rod of nail 4 can be in contact with beeline with the boring cutter 5 in boring cutter hole, and boring cutter 5 is realized and fixed.Set on the handle of a knife 1
Vernier is equipped with, fine setting lock-screw 2 is provided with the dial.After fine setting lock-screw 2 is unclamped, pass through regulation
Vernier can reach the effect of micrometer adjustement boring tool 5, can more be accurately controlled the diameter cutting-in change of boring cutter 5.Such as Fig. 3 institutes
Show, the front end face of the side-strengthened lock-screw 4 is arranged to sphere type, and coupling mechanism force is acted directly on the bar locating surface of boring cutter 5, circle
Coupling mechanism force is implemented in the contact of ball point so that boring cutter 5 is more firm, is not easy to loosen.
The present embodiment uses a diameter of φ 16mm of the connecting shaft 6 of eccentric disc 3；Boring cutter aperture on eccentric disc 3 is φ
16mm；During processing, the φ 16mm connecting shafts 6 of eccentric disc 3 are arranged on handle of a knife 1, eccentric disc 3 consolidated by fixing screws 7
It is fixed, then boring cutter 5 is arranged in the φ 16mm boring cutters hole on eccentric disc 3, the bar of boring cutter 5 is carried out by side-strengthened lock-screw 4
Locking.Start processing when, the main shaft of the universal numerical control lathe of handle of a knife 1 drives rotation, the work of the cutting edge of boring cutter 5 in eccentric disc 3
Certain offset is produced with lower, into prebored hole, then realizes the function of boring cutting.
As shown in Fig. 2 the boring of different pore size is met by the adjustment to H values, such as the bore hole scope 8- of former boring cutter 5
50mm, bore hole scope increases to 70 mm when H values are worked into 10 mm, compensate for former boring cutter 550-70 mm blank, enhances
The use range of original boring cutter 5, hence in so that the job area of boring cutter 5 is extended, the boring of larger aperture can be processed
Work.Before processing by unclamping the fine setting lock-screw 2 on handle of a knife 1, rotary fine adjustment dial（Dial often rotates a small lattice
Represent 0.01mm diameter cutting-in change）, make amount of movement to the exact numerical calculated, it is achieved thereby that the fine setting work(of boring cutter 5
Can, meet the boring processing of different pore size.
