Description
Technical field
The present invention relates to machining equipment more particularly to a kind of turning cutting tools suitable for processing large-lead screw.
Background technique
Large-lead screw is the common part of machinery field passing movement and power.The processing method of large-lead screw is very
It is more, such as turning, milling, grinding, milling with whirling cutter and cold rolling etc., but in small lot, the big screw pitch of single-piece production general precision
When screw rod, most efficient method is that turnery processing is carried out on lathe, since cutting depth total in process is bigger, penetration of a cutting tool
Deep, feed is fast, and chipping allowance is big, and resistance to cutting is bigger, and the turning difficulty for resulting in large-lead screw is larger.Be mainly manifested in
Under several aspects: 1) radial cutting force is big, and screw rod is caused to easily deform；2) since Cutting Force is excessive, so that knife in turning
The vibration of tool and workpiece is larger, causes surface quality not easy to control；3) large-lead screw screw thread modulus and lead are all big, lead angle
Increase, lathe tool rigidly reduces, and sharpening difficulty increases；So that machining accuracy and surface quality are not easy to control in turning, working strength
Greatly, low efficiency.
When vehicle steep-pitch thread, due to the influence of lead angle, the change in location of cutting plane and basal plane is caused, to make
The anterior angle and relief angle of anterior angle and relief angle and lathe tool when static when lathe tool works is unequal.Lead angle is bigger, when to work
Anterior angle and relief angle influence are more obvious.When the anterior angle of lathe tool stationary state is zero degree, lead angle can make one side tool of direction of feed
The anterior angle of sword becomes positive value, and another side rake is made to become negative value, make cutting not smoothly, chip removal it is also difficult.Item is cut to improve
Part needs to take vertical dress knife method, that is, the plane and hand of helix for allowing two side edge of lathe tool to form are vertical, make the work of two side edges
It is zero degree as anterior angle；Or the chip curling groove of larger anterior angle, screw thread liter are ground along two sides cutting edge direction on the rake face of lathe tool
Angle can make lathe tool become smaller along the working orthogonal clearance of one side of feeding, and increase the working orthogonal clearance of another side, to cut smoothly, guarantee vehicle
The relief angle of threading tool direction of feed one side when lathe tool sharpens, is often worn into working orthogonal clearance and adds lead angle by knife intensity,
That is (3 °~5 °)+Ψ；The relief angle of another side wears into working orthogonal clearance and subtracts a lead angle, i.e. (3 °~5 °)-Ψ, though in this way
Machining steep-pitch thread so can be smoothly carried out, but since the relief angle of feed side increases, tool strength is caused to reduce,
Meeting is so that processing efficiency is greatly lowered.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, provide a kind of simple and reliable for structure, cutter
The turning cutting tool for being suitable for processing large-lead screw that back angle is flexibly adjustable, cutter self-strength is high, high in machining efficiency.
In order to solve the above technical problems, the invention adopts the following technical scheme:
A kind of turning cutting tool suitable for processing large-lead screw, including threading tool, knife bar and tool apron, the lathe tool are installed on
The head of the knife bar, the tool apron are equipped with mounting hole, and the shank of the knife bar is inserted in the mounting hole of the tool apron simultaneously
It can be rotated relative to the tool apron, the tool apron is equipped with the fastener for locking the knife bar.
As a further improvement of the above technical scheme: the tool apron is fixedly installed with close to one end of the threading tool
Rotation scale, the shank of the knife bar pass through the center of the rotation scale.
As a further improvement of the above technical scheme: the tool apron is elastic tool apron, offers and is used on the tool apron
Eliminate the weakening groove of the vibration in process, axial direction arrangement of the weakening groove along the knife bar shank.
As a further improvement of the above technical scheme: the shank of the knife bar and the mounting hole clearance fit.
As a further improvement of the above technical scheme: the head of the knife bar includes substrate and a pair of of C-shaped clamp plate, described
Substrate include semicircular part and with the square department that is connected at semicircular part diameter, the axis of the knife bar shank and the substrate
Normal is vertical, and the clamping plate arranges that the substrate is arranged in the clamping plate along the normal direction of the substrate, the threading tool folder
It is fixed between a pair of clamping plate and through fastener.
As a further improvement of the above technical scheme: the substrate is casting integrated molding structure with the clamping plate.
As a further improvement of the above technical scheme: the clamping plate both ends are equipped with fastener receptacles.
Compared with the prior art, the advantages of the present invention are as follows: the vehicle disclosed by the invention for being suitable for processing large-lead screw
Threading tool is installed on the head of knife bar by cutting knife tool, and the shank of knife bar is inserted in the mounting hole of tool apron, and shank and tool apron
Can relative rotation, the shank of knife bar is locked by the fastener on tool apron, it can be achieved that threading tool phase after dismantling the fastener
Rotation to tool apron can arbitrarily adjust the back angle of threading tool when processing large-lead screw according to lead, not only can be with
Processing dextrorotation, it is left-handed can also process the steep-pitch threads such as end face, when sharpening, need to only be carried out by normal tool clearance, and
Direction of feed need not be increased to a helix angle, subtracted a helix angle by direction of feed, ensure that the strong of cutter itself
Degree, reduces the cost of charp tool, is conducive to improve processing efficiency.
