Description
Technical field
A kind of gang tool is the utility model is related to, has step cylindrical for turning or the workpiece of inner circle.
Background technology
Processing efficiency can be improved using gang tool on lathe, such as processing has step cylindrical or the workpiece of inner circle
When, different-diameter position can be processed simultaneously；But the radial distance adjustment between gang tool is relatively time-consuming, especially
When being that processed workpiece accuracy is higher, technical requirements can just be met by repeatedly adjusting repeatedly.It is necessary to design a kind of group for this
Close the adjustment structure of cutter.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of combination lathe tool, to facilitate between adjustment lathe tool
Radial distance.
The technical solution of the utility model is that one kind combination lathe tool, it includes cutter hub 3, on cutter hub laterally spacedly
First knife bar 1, the second knife bar 2 are installed, the first knife bar and the second knife bar stretch out along longitudinal direction from cutter hub, what the second knife bar stretched out
Length is more than the length that the first knife bar stretches out, it is characterized in that, the first knife bar and the second knife bar are ordinatedly inserted in cutter hub, on cutter hub
Provided with the trip bolt 8 for compressing the first knife bar, the second knife bar, cutter hub, which is provided with, withstands the adjusting screw 4 at the first knife bar rear portion, and one
The front end of micrometer adjusting screw 9 is spun in the rear portion of the second knife bar, and the rear end of micrometer adjusting screw 9 is spun in cutter hub, the front end of micrometer adjusting screw 9
Provided with the first screw thread 6, the second screw thread of rear end 7 of micrometer adjusting screw 9, the pitch of the second screw thread is slightly larger than the pitch of the first screw thread, the
The rotation direction of one screw thread and the second screw thread is identical.
The characteristics of the utility model is that adjusting screw and micrometer adjusting screw are provided with cutter hub, and adjusting screw is used for the first knife
The coarse adjustment of relative length between bar and the second knife bar, micrometer adjusting screw are used for fine tuning, and micrometer adjusting screw rotates one week, the shifting of the second knife bar
Dynamic size is the pitch difference of the first screw thread and the second screw thread, and the regulation of the smaller second knife bar movement of pitch difference is finer.With it is existing
Technology compares the combination lathe tool with fine tuning structure, greatly facilitates the regulation of relative size between knife bar.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 A-A to sectional view.
Accompanying drawing mark represents respectively：The knife bars of 1- first, the knife bars of 2- second, 3- cutter hubs, 4- adjusting screws, 5- guide grooves, 6-
First screw thread, the screw threads of 7- second, 8- trip bolts, 9- micrometer adjusting screws.
Embodiment
In conjunction with brief description of the drawings specific embodiment of the present utility model.
One kind combination lathe tool, it includes cutter hub 3, is provided with the first knife bar 1, the second knife bar laterally spacedly on cutter hub
2, the first knife bar occupies the cutter head of the front end provided with turning on left, the second knife bar residence right side, the first knife bar and the second knife bar, the first knife bar
Stretched out with the second knife bar along longitudinal direction from cutter hub, the length that the second knife bar stretches out is more than the length that the first knife bar stretches out, its feature
It is that the first knife bar and the second knife bar are ordinatedly inserted in cutter hub, cutter hub, which is provided with, compresses the first knife bar, the fastening spiral shell of the second knife bar
Nail 8, cutter hub are provided with the adjusting screw 4 for withstanding the first knife bar rear portion, and the front end of a micrometer adjusting screw 9 is spun on the rear portion of the second knife bar
In, the rear end of micrometer adjusting screw 9 is spun in cutter hub, and the front end of micrometer adjusting screw 9 is the first screw thread 6, and the rear end of micrometer adjusting screw 9 is second
Screw thread 7, the pitch of the second screw thread are slightly larger than the pitch of the first screw thread；The rotation direction of first screw thread and the second screw thread is identical.
Adjusting screw is used for the coarse adjustment of relative length between the first knife bar and the second knife bar, and coarse adjustment, which finishes, tightens corresponding first
The trip bolt of knife bar.
Micrometer adjusting screw is used for fine tuning, and micrometer adjusting screw rotates one week, and the amount of movement of the second knife bar is the second screw thread and the first spiral shell
The pitch difference of line, the regulation of the smaller second knife bar movement of pitch difference are finer.The pitch for selecting the second screw thread is 1.5mm, the first spiral shell
The pitch of line is 1.25mm, and the amount of movement that micrometer adjusting screw rotates one week the second knife bar is 0.25mm；Fine setting, which finishes, tightens corresponding the
The trip bolt of two knife bars.
The first described knife bar and the section of the second knife bar for it is circular when, to prevent knife bar from rotating, in the first knife bar and the
Guide groove 5 is respectively equipped with two knife bars, the front end of trip bolt 8 is located in guide groove.When the first knife bar and section of the second knife bar
When face is rectangle, guide groove is not set.
