Description
Technical field
The present invention relates to a kind of metal processing sectors, specifically a kind of fermentation tank fastening screw chasing processing technique.
Background technology
The application of screw thread widely, especially connection between machine components and grappling in transmission.In machining, make
Processing on a shaft with rotation and the cutter of movement or emery wheel, the vestige cut out just has become screw thread.Screw thread be divided into female thread and
External screw thread, the screw thread cut out at endoporus is called female thread, and the screw thread cut out at outer surface is external screw thread.Section according to screw thread is not
With, screw thread also can be divided into angular thread, trapezoidal thread, saw-tooth thread, square thread, circular thread etc..Machining screw thread
Machining is realized by gang tool, can carry out the production of large batch of thread part, screw thread in prior art
Processing mode is as follows: (1) thread turning, and screw thread car pin refers to cutted thread on lathe, two kinds of cutters of general employing: shape car
Cutter and chaser.Former structure is simple, it is adaptable to single-piece and small lot screw thread produce；Latter configuration is complicated, and production efficiency is high,
It is applicable to big-and-middle batch closely-pitched short thread produce.Along with the development of numerical control machine tool technique, most machine shop all uses
Lathe in machining, numerically controlled lathe can uninterruptedly be processed, it is adaptable in high volume, complex-shaped part.(2) thread milling,
Screw-thread miller typically uses disc milling cutter and Comb milling cutter, and the former is for processing the trapezoidal thread on the workpiece such as screw mandrel, worm screw；After
The working portion length of person is the longest, only need to rotate 1.4 and turn left and right just can process screw thread, and production efficiency is the highest, mainly uses
Surfaces externally and internally and tapered thread in regular screw threads.Pitch precision is produced in thread milling and surface roughness is the highest, this method
It is applied to mass production but the highest screw thread of required precision or semi-finished product.Along with the development of science and technology, provide spy for manufacturing enterprise
The machining center of different service produces.In view of the high efficiency of milling thread, machining center many employings Milling Process.(3) thread grinding,
Thread grinding is to carry out hardening the Precision Machining of workpiece on screw grinder, can be divided into single line wheel grinding and multi-thread wheel grinding
Two classes.The precision of single line wheel grinding is the highest, and maximum pitch precision can reach 5 to 6 grades, and surface roughness can reach R1.25-
0.08μm.Single line wheel grinding production efficiency is the highest, it is adaptable to the production of small lot, is applied to precision lead screw, worm screw, spiral shell
Screw ga, accurate hobboing cutter etc..Multi-thread wheel grinding can be divided into again incision mill and longitudinal grinding.The feature of incision mill is grinding workpiece screw thread
Length is less than the width of emery wheel, and workpiece only need to turn 5/4 turn of just energy milled, and machining accuracy is the highest, is unfavorable for that emery wheel is rested and reorganized, it is adaptable to
Large batch of screw tap is used for the screw thread of fastening with some；The feature of longitudinal grinding is the grinding workpiece reach width more than emery wheel,
Longitudinal grinding emery wheel just directly can become the final size needed screw thread process by stroke several times.(4) screw thread grinds, and screw thread grinds
It it is the reworking carried out to improve the precision of screw thread.The instrument that it uses is made by soft material (cast iron etc.), presses
Shape is divided into nut type and screw type, and nut type is used for grinding external screw thread, and screw type is used for grinding female thread.Pass through positive and negative rotation
Grinding, screw thread grinds the pitch that can revise screw thread, improves the precision of pitch, it is also possible to eliminate the female thread deformation after hardening.
(5) tapping and mantle fiber, tapping is used for machining internal thread, is to be rotatably inserted into screw tap on workpiece in reserved hole to process screw thread,
Being applicable to the internal thread machining of minor diameter, accuracy of thread depends on the precision of screw tap, can process by hand, it is possible to use car
Bed, drilling machine, tapping machine etc..Mantle fiber be used for threading, be to cut out screw thread with screw die at outer surface of workpiece, the precision of screw thread by
The precision controlling of screw die, can be processed by modes such as craft, lathe, drilling machine, die head threading machines.
