Specific embodiment
It is below in conjunction with the accompanying drawings and specific real in order to which those skilled in the art is made to more fully understand technical scheme
Applying example, the present invention is described in further detail.
As shown in Fig. 3 and Fig. 4, Fig. 7 and Fig. 8, a kind of hobboing cutter for processing screw rotor, including with endoporus 5 and axis platform 4
Cutter hub.It is evenly distributed on cutter hub to have cutter tooth.Chip pocket 6 between cutter tooth is parallel with the axis of cutter hub.Cutter tooth be multiple rows of multiple row, knife
Tooth is the circumferential helical arrangement along cutter hub.There is 10-18 row's cutters tooth and chip pocket 6 on cutter hub.Due to the chip pocket 6 of rotor hob
For the straight trough parallel with axis, so its contrate tooth profile is straight line, axial tooth profile is identical with normal tooth profile.
As shown in Fig. 5 and Fig. 6, Fig. 9 and Figure 10, since present invention screw rotor to be processed is divided into female rotor and sun turn
Son, so cutter hub has two pairs, a secondary cutter hubs for female rotor hobboing cutter 3, another width is the cutter hub of male rotor hobboing cutter 8.According to space
The theory of engagement goes out the tooth form of respective rotor hobboing cutter cutter tooth by the tooth form inverse of screw rotor.The tooth form of female rotor hobboing cutter cutter tooth 7
It is engaged with the tooth socket of female rotor.In the tooth form of female rotor hobboing cutter cutter tooth 7, tooth top and tooth root are smoothly connected.Male rotor hobboing cutter knife
The tooth form of tooth 9 is engaged with the tooth socket of male rotor.In the tooth form of male rotor hobboing cutter cutter tooth 9, tooth top and tooth root are smoothly connected.
A kind of production method for processing screw rotor hob, it is specific as follows：
Step 1：Two secondary identical bars are carried out with spudding in for endoporus 5, vehicle shaft platform 4, to determine the cutter hub of rotor hob
Length.
Step 2：Go out thread tooth along the circumferential vehicle of cutter hub on the basis of step 1, and appearance bits are milled out along the axial direction of cutter hub
Slot 6 obtains the cutter blank of two secondary rotor hobs.
Step 3：Teeth is carried out using female rotor hobboing cutter perching knife 10 to the secondary cutter blank in step 2, obtains rough machined the moon
Rotor hob 3；Teeth is carried out using male rotor hobboing cutter perching knife 13 to another secondary cutter blank in step 2, rough machined sun is obtained and turns
Sub- hobboing cutter 8.The teeth processing carried out in this step needs to leave staying for 0.3~0.5mm for the Relieving manufacturing in subsequent step
Amount., it is necessary to be heat-treated to rotor hob after teeth machines, 65~67HRC of heat treatment hardness.Heat treatment is completed
Afterwards, the endoporus 5 to rotor hob, axis platform 4 are ground, and then carry out grinding of putting the first edge on a knife or a pair of scissors to the preceding cutting edge of hobboing cutter.
Step 4：Relief grinding is carried out using female rotor hobboing cutter emery wheel 15 to rough machined female rotor hobboing cutter 3 in step 3, obtains essence
The female rotor hobboing cutter 3 of processing；Relief grinding is carried out using male rotor hobboing cutter emery wheel 17 to rough machined male rotor hobboing cutter 8 in step 3, is obtained
The male rotor hobboing cutter 8 that must be finished.
It should be noted that as shown in Figure 11 and Figure 12, Figure 15 and Figure 16,11 shape of blade of female rotor hobboing cutter perching knife and
16 shape of grinding sword of female rotor hobboing cutter emery wheel is consistent, is determined by the tooth form of female rotor hobboing cutter cutter tooth 7.And female rotor hobboing cutter knife
The tooth form of tooth 7 is obtained by the tooth form inverse of female rotor in screw rotor.As shown in Figure 13 and Figure 14, Figure 17 and Figure 18, sun turns
14 shape of blade of sub- hobboing cutter perching knife is consistent with 18 shape of grinding sword of male rotor hobboing cutter emery wheel, by male rotor hobboing cutter cutter tooth 9
Tooth form determine.And the tooth form of male rotor hobboing cutter cutter tooth 9 is obtained by the tooth form inverse of male rotor in screw rotor.
It is processed for the teeth in step 3, the rotating speed of rotor hob is according to its outer diameter size between 10~15r/min.
The depth of cut of perching knife is divided into slightly shovel and essence is shoveled, and is slightly 0.05~0.15mm during shovel, is 0.01~0.03mm when essence is shoveled.Such as Figure 21 institutes
Show, during teeth, perching knife movement locus 21 is to carry out teeth processing along 12 curve of tooth top relief angle of rotor hob, to be protected
It is logical to demonstrate,prove the tooth form whole shovel of rotor hob, and the latter row's cutter tooth of wound cannot be shoveled.When being detected to teeth precision, perching knife is put
It is qualification when perching knife flank profil and hobboing cutter flank profil are seamless in the cutting edge of rotor hob.
For the Relieving manufacturing in step 4, the rotating speed of rotor hob is controlled in 2500~3500r/min, linear velocity 25
~35m/min.The relief grinding amount of feeding is divided into corase grinding and fine grinding, is 0.02~0.05mm during corase grinding, during fine grinding for 0.005~
0.01mm.As shown in figure 22, during relief grinding, relief grinding movement locus is 12 curve of the tooth top relief angle progress along rotor hob
Relieving manufacturing, it is ensured that cannot damage latter row's cutter tooth during relief grinding, and cutter tooth afterbody does not allow to protrude.To relief grinding precision into
It during row detection, is detected using amplification projecting apparatus, projection multiple is 10~20 times.Rotor hob need to rotate detection during detection,
The tooth form of rotor hob is qualification when in the enlarged drawing tolerance with tolerance under rotational case.Profile error generally exists
Within 0.005mm.
It can be seen from the above, production rotor hob is related to two kinds of important process tools for perching knife and emery wheel.Both add
The specific method of work cutter is as follows：
The processing method of female rotor hobboing cutter perching knife 10 and male rotor hobboing cutter perching knife 13 is：Forging is passed sequentially through using high-speed tool steel
It beats, finish-milling cutter blank, technique one cuboid cutter blank of acquisition by hardness heat treatment for 65~67HRC.As shown in figure 19, this is rectangular
Body cutter blank obtains one end with the female rotor hobboing cutter perching knife 10 of cutting edge shape and male rotor hobboing cutter perching knife by 19 wire cutting of molybdenum filament
13.Female rotor hobboing cutter perching knife 10 and male rotor hobboing cutter perching knife 13 be respectively provided with 30~35 ° tooth top relief angle 12 and 3 ± 0.2 ° of side edge
Relief angle, therefore, perching knife need to be installed at an angle during wire cutting, in order to form relief angle after the completion of wire cutting.Wire cutting
Shi Caiyong slow wire feedings, 0.1~0.3m/s of feeding speed.
The processing method of female rotor hobboing cutter emery wheel 15 and male rotor hobboing cutter emery wheel 17 is：Using the emergy of 80~100
Wheel, emery wheel outer diameter is according to the emery wheel of a diameter of 50~150mm of structure choice of rotor hob.Cylindrical emery wheel blank is at the uniform velocity
In the state of rotation, modified by diamond roller 20 and obtain female rotor hobboing cutter emery wheel 15 and male rotor of the outer diameter with grinding sword
Hobboing cutter emery wheel 17, as shown in figure 20.In finishing, using 2500~3000r/min, the rotating speed of idler wheel 20 uses the rotating speed of rotating speed
4000~6000r/min.The amount of feeding uses 0.01~0.05mm.
The rotor hob obtained by above-mentioned production and processing has tooth form that can be at a fully engaged with screw rotor, becomes
A kind of full cut type screw rotor hob, that is to say, that the root position of rotor hob profile can also participate in cutting in the present invention.
This means that once transforms into the screw rotor that gear hobbing is obtained using the present invention, and the use that precision can reach workpiece will
It asks.Not only high precision machining, but also without carrying out the grinding in original processing method again, therefore reduce production cost.
