Background technique
Worm screw is that one kind has one or more helical tooths and engages with worm gear, and staggeredly between centers moves the tooth with power for transmitting
Wheel.Since Worm Wheel System has many advantages, such as large transmission ratio, strong bearing capacity, steady transmission, the tooth accuracy of worm screw
It is more demanding.Compared to other kinds of worm screw, involute helicoid worm can be processed accurately, and tooth accuracy can be guaranteed, with snail
It is good to take turns meshing performance, is suitable for big load, high revolving speed, long-term continuous transmission occasion.
Currently, the processing method of worm screw mainly has machining and rolling forming processing two major classes.Because rolling forming is processed
Have the advantages that few waste of material, Gear Surface Strength and high production efficiency, is widely applied in low-modulus worm processing.But
The worm tooth-surface precision of rolling forming is not high, and is difficult to shape large modulus, big screw pitch worm screw, and therefore, machining is still current
Large modulus, big screw pitch, the main method of high-precision worm screw production.
Compared to Milling Process, worm screw turnery processing is low for equipment requirements, and cutter is simple, manufacture and installation are square
Just, therefore, turning is still the most wide method of worm screw processed and applied.Currently, the cutter base of turnery processing is carried out to involute helicoid worm
This is all white steel cutter, and the involute of cutter is formed by spark cutting.It is rotten to form pit shape for the cutter flank of tooth after cutting
Layer, is also easy to produce micro-crack, and the only partially soft worm screw of Material Processing, such as copper worm screw.
It is general or using cutter made of being ground in the worm screw of the harder material of turning, but due to Material Processing compared with
Firmly, the blade of cutter is prone to wear when in use, once edge wear is excessive, cutter will be removed and be ground again, again
When installation, cutter is also needed to knife, so repeatedly installing and dismounting, causes process very complicated.

Hole, the nut be screwed together in the fixed column and by the tungsten steel blade be located in the nut and the cutter head upper surface it
Between；
The tungsten steel blade is successively arranged bottom of the tooth blade, involute knife from the tip of the tungsten steel blade towards the knife bar
Sword and tooth top blade.
Preferably, the radius of the nut is less than the radius of the waist hole and the edge of the waist hole to the involute knife
The sum of the distance of sword.
Preferably, the edge of the radius of waist hole described in the radius ratio of the nut and the waist hole is to the involute blade
The small 1-2mm of sum of the distance.
Preferably, washer is equipped between the nut and the tungsten steel blade.
Preferably, the cutter head and knife bar are made of Bai Gang.
Preferably, the cutter head and knife bar are integrally formed.
Preferably, the fixed column is cylinder.
The positive effect of the utility model is: the tungsten carbide tipped tool uses dismountable tungsten steel blade, thus
When blade needs repairing type, can removal of inserts, during installation can by adjust the distance between blade and workpiece it is accurate
Installation, avoids repetition to knife, saves labour.

Specific embodiment
With reference to the accompanying drawing, the utility model is further illustrated by way of embodiment, but therefore will be originally unpractical
It is novel to be limited among following scope of embodiments.
As shown in Figure 1-3, tungsten carbide tipped tool is for cutting involute helicoid worm, tungsten carbide tipped tool include: cutter head 100, knife bar 400,
Tungsten steel blade 300, fixed column 110, nut 200.
Cutter head 100 is set to one end of knife bar 400, and fixed column 110 is fixedly arranged on the upper surface of cutter head 100, on tungsten steel blade 300
Equipped with a waist hole 340, tungsten steel blade 300 is set to the upper surface of cutter head 100 and fixed column 110 is arranged in waist hole 340, nut
200 are screwed together in fixed column 110 and tungsten steel blade 300 are located between nut 200 and the upper surface of cutter head 100.
Tungsten steel blade 300 is successively arranged bottom of the tooth blade 310, involute knife from the tip of tungsten steel blade 300 towards knife bar 400
Sword 320 and tooth top blade 330.
Bottom of the tooth blade 310, involute blade 320, tooth top blade 330 size determined by processed worm screw flank profil.
Waist hole 340 has certain length, with allow the blade to slide in waist hole 340 so as to adjust blade to workpiece away from
From.
The radius of nut 200 be less than waist hole 340 radius at a distance from the edge of waist hole 340 to involute blade 320 it
With.
Fixed column 110 is located at the lateral intermediate position of cutter head 100, and diameter is determined by nut 200, and axial (knife bar 400
Extending direction) position determines by following formula:
S=R+h.
Wherein, S is minimum range of 110 center of fixed column to knife edge, unit mm；
R is the outer diameter of nut 200, unit mm；
H is anti-interference gap, h=1-2mm.
The sum of the distance of the radius of the radius ratio waist hole 340 of nut 200 and the edge of waist hole 340 to involute blade 320
