Description
Technical field
The invention belongs to Technology for Turning Machining fields, more particularly to a kind of pendulum that can reduce the turning insert rate of wear
Dynamic formula knife rest.
Background technique
Currently, turning insert is scrapped because of excessive wear to be inevitable, often when processing part by turning mode
Part can consume a large amount of turning insert after completing turnery processing, and the material cost of turning insert will also be included in part
Processing cost in, this virtually improves the manufacturing cost of part.
Many processing enterprises are all in the turning insert consumption reduced in part processing by every means, in the system of part
Present aspect is caused to obtain advantage, but actual effect is unsatisfactory, the consumption of turning insert is still high.
It before turnery processing, needs for turning insert to be installed on knife handle, then knife handle is installed to the fixed knife rest of lathe
On, after completing to knife, formal turnery processing can be started.Since the blade of turning insert is mostly arc-shaped, Tutrning Process
In, a part of cutting edge of arc-shaped blade can only be utilized for cutting, and other positions of cutting edge can not be utilized, especially
Cutting force and cutting heat meeting long duration of action cause tipping phenomenon to happen occasionally on the part cutting edge, once turning insert is sent out
Raw tipping, then declare that the turning insert is scrapped, the turning insert that can only more renew continues to process.Even if it is existing that there is no tippings
As for this part of cutting edge for cutting under prolonged cutting force and cutting heat effect, edge wear speed is very fast
, when edge wear reaches to a certain degree, even if remaining to continue on for cutting, operator will not continue to use the turning
Blade can bring the machining accuracy of piece surface and seriously affect, in order to guarantee parts list because the abrasion with blade aggravates
The machining accuracy in face, over worn turning insert will also scrap processing to blade.
Therefore, it is desirable to reduce turning insert consumption, can only start with from the turning insert rate of wear is reduced, if it is possible to fill
Divide whole cutting edges using arc-shaped blade, while avoiding cutting force and cutting heat long duration of action on the cutting edge of part, just has
It may be decreased the turning insert rate of wear.But the function restriction by conventional fixed-type knife rest, it is desirable to make full use of arc-shaped
Whole cutting edges of blade are difficult to realize.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of swing type that can reduce the turning insert rate of wear
Knife rest can utilize the arc-shaped blade whole cutting edge of turning insert for cutting, make the effect of cutting force and cutting heat equalization
On whole cutting edges, the occurrence probability of tipping phenomenon is effectively reduced, realizes the uniform wear of arc-shaped blade, grinds turning insert
Damage speed is greatly lowered, and then reduces the consumption of turning insert.
To achieve the goals above, the present invention adopts the following technical scheme: one kind can reduce the turning insert rate of wear
Swing type knife rest, including pedestal body, lifting driving motor, screw rod, screw, lifting table plate, pinboard and swing handle mechanism；
The screw rod is vertically installed on pedestal body, and the lifting driving motor is mounted on pedestal body top, and goes up and down driving motor
Motor shaft is fixedly connected with screw rod；The nut sleeve is on screw rod, and the lifting table plate is connected on screw, the swing knife handle
Mechanism is fixedly connected with by pinboard and lifting table plate, and turning insert, which is mounted on, to be swung on handle mechanism.
Riser guide is installed on the pedestal body, riser guide is parallel with screw rod, is provided on riser guide
Sliding block, sliding block are fixedly connected with lifting table plate.
The swing handle mechanism includes quiet plate, movable plate, toolholder body and rotation driving motor；The quiet plate is connected in switching
On plate, quiet plate is connected with movable plate by arc track, and the toolholder body is connected on movable plate, and turning insert is mounted on toolholder body
On；Arc-shaped rack is provided on the movable plate；The rotation driving motor is fixedly mounted on pinboard, rotation driving motor
A worm screw is fixed on motor shaft, worm screw is meshed with arc-shaped rack；The centre of gyration of the arc track and arc-shaped rack
Line coincides, and the center of circle of the arc-shaped blade of turning insert is located on the centre of gyration line of arc track and arc-shaped rack.
The arc track uses dovetail type track structure.
Beneficial effects of the present invention:
Compared with prior art, the present invention the arc-shaped blade whole cutting edge of turning insert can be utilized for cutting, make
Cutting force and cutting heat are impartial to be acted on whole cutting edges, and the occurrence probability of tipping phenomenon is effectively reduced, realizes arc-shaped knife
The turning insert rate of wear is greatly lowered in the uniform wear of sword, and then reduces the consumption of turning insert.

Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figures 1 to 3, a kind of swing type knife rest can reduce the turning insert rate of wear, including pedestal body 1, liter
It drops driving motor 2, screw rod 3, screw, lifting table plate 4, pinboard 5 and swings handle mechanism；The screw rod 3 is vertically installed at base
On frame body 1, the lifting driving motor 2 is mounted on 1 top of pedestal body, and the motor shaft of lifting driving motor 2 and 3 phase of screw rod are solid
Even；The nut sleeve is on screw rod 3, and the lifting table plate 4 is connected on screw, and the swing handle mechanism passes through pinboard
5 are fixedly connected with lifting table plate 4, and turning insert 6, which is mounted on, to be swung on handle mechanism.
Riser guide 7 is installed on the pedestal body 1, riser guide 7 is parallel with screw rod 3, sets on riser guide 7
It is equipped with sliding block 8, sliding block 8 is fixedly connected with lifting table plate 4.
The swing handle mechanism includes quiet plate 9, movable plate 10, toolholder body 11 and rotation driving motor 12；The quiet plate 9 is solid
It is connected on pinboard 5, quiet plate 9 is connected with movable plate 10 by arc track 13, and the toolholder body 11 is connected on movable plate 10, turning
Blade 6 is mounted on toolholder body 11；Arc-shaped rack 14 is provided on the movable plate 10；The fixed peace of the rotation driving motor 12
It fills on pinboard 5, a worm screw 15 is fixed on the motor shaft of rotation driving motor 12, worm screw 15 nibbles with 14 phase of arc-shaped rack
It closes；The centre of gyration line of the arc track 13 and arc-shaped rack 14 coincides, and the center of circle of the arc-shaped blade of turning insert 6
On the centre of gyration line of arc track 13 and arc-shaped rack 14.
The arc track 13 uses dovetail type track structure.
Illustrate first use process of the invention with reference to the accompanying drawing:
After lathe is mounted with swing type knife rest of the invention, starting goes up and down driving motor 2 first, to lifting table plate 4
Height and position is adjusted, until turning insert 6 is adjusted to Working position.
It completes to start machining, while starting rotation driving motor 12 to knife by lathe, worm screw 15 is driven to rotate,
It drives arc-shaped rack 14 to move by worm screw 15, and then movable plate 10 is promoted to make swinging motion along arc track 13, due to turning
The center of circle of the arc-shaped blade of blade 6 is located on the centre of gyration line of arc track 13 and arc-shaped rack 14, passes through movable plate 10
Swinging motion makes the arc-shaped blade whole cutting edge of turning insert 6 for cutting, and so, cutting force and cutting heat can
Impartial acts on whole cutting edges, effectively reduces the occurrence probability of tipping phenomenon, realizes the uniform mill of arc-shaped blade
Damage, is greatly lowered the rate of wear of turning insert 6, and then reduces the consumption of turning insert 6.
The scope of patent protection that scheme in embodiment is not intended to limit the invention, it is all without departing from carried out by the present invention etc.
Effect implements or change, is both contained in the scope of the patents of this case.
