Abstract
The utility model is related to a kind of combination knife bar for slender axles accessory turning, including centre frame, cutter hub, knife rest, feed leading screw and adjusting bolt.It is mainly characterized by being fixed on the centre frame on cutter hub and supports slender axles in the flank of tool equipped with adjusting bolt, so as to substantially reduce the distance of workpiece support point, the local stiffness that workpiece is processed area is added, so as to improve machining accuracy and processing efficiency.
Description
Technical field
The utility model is related to a kind of field of machining, and in particular to a kind of combination knife bar for turning slender axles.
Background technology
In the prior art, the turning of slender axles uses centre frame or follow-rest method always.Technology development in recent years
In, the technology of follower rest is employed, such as " ultra-fine long bolt turning special purpose device ".But in ultra-fine axle（L/d is more than 80-
150）Processing in, because cutter and centre frame have certain distance, the rigidity of workpiece is still not enough, thus influence processing efficiency and
Machining accuracy.
The content of the invention
The purpose of this utility model is a kind of Novel shaft combination knife bar of design, to improve the processing rigidity of superfine shaft,
Improve machining accuracy and efficiency.
The utility model adopts the technical scheme that to solve above-mentioned technical problem：The utility model is to be directed to superfine shaft
Processing characteristic be designed, by centre frame, cutter hub 5, knife rest 3, feed leading screw 6, the grade of adjusting bolt 1 part composition, this dress
Put can clamping is on lathe squaring head as regular turning tool, centre frame 2 is fixed on cutter hub 5 with screw 8, and pass through adjustment
Screw 1 supports slender axles in the flank of tool simultaneously respectively, so as to substantially reduce the distance of workpiece support point, adds ultra-fine length
Shaft-like work is processed the local stiffness in area.Feed leading screw 6 combined and fixed with sliding block 10 by screw 7, feed by knife bar in itself
Feed screw 6 is with movable slider 10, so as to be realized with movable knife rack 3, there is four cutter holders on knife rest 3, can install four simultaneously on demand
Lathe tool, cutter holder screw 9 is fixed.
The utility model has the advantages that：Using this combination knife bar processing thin and long shafts part, it can carry significantly
High processing efficiency, processing efficiency can improve 10 times, particularly to superfine shaft class part or superfine axle（Draw ratio L/d>
80-150）Processing, improve processing efficiency and machining accuracy effect become apparent.
Brief description of the drawings
Fig. 1 is the longitudinal section of centre frame part of the present utility model；Fig. 2 is follow-rest part-structure of the present utility model
Figure；Fig. 3 is body portion partial sectional view of the present utility model.In figure：1. mounting screw, 2. follow-rest bodies, 3. handwheels, 4. bullets
Spring, 5. spring abutments, 6. push rods, 7. with cutter claw, 8. adjusting screws, 9. mounting screws, 10. feed leading screws, 11. cutter hubs, 12. adjustment spiral shells

Embodiment
Embodiment：Illustrate present embodiment, centre frame as shown in Figure 1, with cutter claw 7 with reference to Fig. 1, Fig. 2 and Fig. 3
On push rod 6, push rod on the follow-rest body with cutter claw slide opening, with the push rod of cutter claw behind equipped with push rod spring 5,
Two of its middle and upper part and sidepiece behind the push rod spring of cutter claw with having leaned adjusting screw 8.One of bottom with cutter claw
Push rod spring behind leaned regulating bolt 12, regulating bolt is connected on follow-rest body, this with cutter claw push rod side
Connecting pin on be connected with handwheel 3, hand wheel shaft is connected on follow-rest body 2.The outer end of adjusting screw 8 is connected with handwheel 3, with cutter claw
Push rod spring 4 pass behind spring abutment 5 and be threadedly coupled with adjusting screw 8.There is mounting screw 1 below follow-rest body.This practicality
Novel turning slender axles are by centre frame, with 10 groups of cutter claw 7, spring 4, spring abutment 5, adjusting screw 8 and feed leading screw with follow-rest
Into.
90 are used with cutter clawoArrangement, cutter is just to cutter claw, being conducive to the balance of cutting force.With cutter claw push rod 6
Spring 4 is housed below, and drives leading screw 8 to rotate by the rotation of handwheel 3 provided with adjustable handwheel 3 outside follow-rest so that
Spring abutment 5（Mother lead screw）Axial movement, reaches the pressure adjustment to spring.Following is to lean on regulating bolt 12 to control this with cutter claw
The pressure of spring.
