Abstract
A quick cutter-setting mechanism is disclosed, which structure's feature as follows: the middle of the cutter bar is fixed on the cutter rest via column pin, there is a press spring on the cutter bar nearby blade, the other end of the spring is fixed on the cutter rest, and the other end of cutter bar contacts with the movable aligning pin. Advantages: simple structure, convenient use, easy for changing, capable of repeatedly setting cutting, no broken pin and largely saving cost.
Description
Affiliated technical field
The present invention relates to turned part, specifically, is a kind of lathe fast roll setting device.
Background technology
Fast roll setting device is a kind of special lathe saddle, its effect is to allow cutter break away from workpiece with very fast speed in certain moment of metal cutting process, thereby obtain a smear metal root sample under certain condition, in order to instruct production reality and scientific research, as observe built-up edge, volume chip breaking and vibration for people, research metal cutting deformation process is analyzed cutting scheme.The fast roll setting device that uses in research and production at present mainly contains two kinds: a kind of is the impact type fast roll setting device, cylinder iron make for one in its two steady pins, when needs, beat knife bar in the cutter holder with hand hammer or alternate manner, the cast iron pin is cut off, thereby made cutter hightail workpiece.This apparatus structure is fairly simple, use also very convenient, be at present the most widely used a kind of, but because hand hammer speed is slower, when higher cutting speed, can not satisfy the effect of instantaneous " freezing " cutting, simultaneously the hand hammer drop point differ and strength inhomogeneous, might cause the cast iron pin not cut off or rupture irregular and lost efficacy, more disadvantageously, whenever the cutter that falls just needs to consume a cast iron pin, causes use cost very high.Another kind is the explosion type fast roll setting device, and it is to utilize the explosive force of gunpowder in the piston that cutter is withdrawed from rapidly, and this device can be 10
-3Make cutter break away from workpiece in second time, but big because of its explosive sound, use dangerously, be not used widely.
Summary of the invention
For overcoming the technological deficiency of existing lathe fast roll setting device, the invention provides a kind of easy and simple to handle, not consumptive material, lathe fast roll setting device that result of use is good.
The technical solution adopted for the present invention to solve the technical problems is:
1, a kind of lathe fast roll setting device, it comprises knife rest, knife bar and blade, it is characterized in that, the middle part of knife bar is located on the knife rest by straight pin, the nearly blade place of knife bar is provided with a compression spring, and the other end of compression spring is fixed on the knife rest, the other end of knife bar and activity orientation pin contacts.
According to above-mentioned 1 described lathe fast roll setting device, it is characterized in that 2, described loose pin is the chamfered edge pin, the alignment pin middle part is provided with-the chamfered edge groove, and the chamfered edge groove of alignment pin contacts with the other end of knife bar, and the alignment pin two ends are rotatable to be located on the knife rest.
The obtained beneficial effect of the present invention is:
1, owing to adopts spring and chamfered edge pin to compress the lathe tool bar jointly, make lathe tool can bear cutting force, the lathe tool bar can straight pin be that axle rotates simultaneously, when the chamfered edge pin rotates, the lathe tool bar can be stablized under the thrust of spring and breaks away from workpiece apace, and handling safety is reliable;
But repeated multiple times roll setting when 2, using, and disconnected pin produces, consumptive material not, thus can save cost greatly;
3, apparatus structure is simple, can be directly installed on the tool rest of lathe, and it is convenient to use, change.
Description of drawings
Fig. 1 is a structural representation of the present invention,
Fig. 2 is the roll setting state diagram.
Among Fig. 1,1. lathe tool bar, 2. straight pin, 3. chamfered edge pin, 4. spring, 5. blade.
The specific embodiment
Below in conjunction with embodiment the present invention is further described.
Embodiment 1:
The present embodiment device comprises knife rest, lathe tool bar 1, blade 5, straight pin 2, chamfered edge pin 3 and compression spring 4, sees Fig. 1.Compression spring is fixedly mounted on the nearly blade of lathe tool bar 1 front end 5 places, and compression spring 4 other ends are fixedly mounted on the knife rest; Lathe tool bar 1 middle part is installed on the knife rest by straight pin 2, and knife bar 1 can rotate around straight pin 2; There is a chamfered edge groove at chamfered edge pin 3 middle parts, and the column part of chamfered edge pin 3 contacts with the other end of knife bar, and chamfered edge pin 3 two ends are rotatable to be installed on the knife rest.When chamfered edge pin 3 turns to the chamfered edge groove, knife bar 1 hightails cutting under the effect of compression spring 4.
When cutting test, knife bar 1 is supported on the straight pin 2 and is compressed by chamfered edge pin 3, bears cutting force, fast during roll setting, rotates chamfered edge pin 3 slightly, and knife bar 1 hightails under the effect of compression spring 4, sees Fig. 2.
Below be to use this device to carry out the roll setting result of the test:
When cutting data is: V
c=8.5-21m/min, a
p=1.2-3.2mm during f=0.05mm/r, shows the roll setting fast stably of this device.
Adopt the present invention to carry out roll setting, gained smear metal root can be observed excellent chip by microscope and form certain instantaneous state of plastic deformation after grinding.
