Abstract
The present invention relates to the manufacturing fields of civil engine special construction stud, belong to a kind of processing method.Specifically related to a kind of full thread processing method with keyway, including conventional processes, secondary turning process is increased in the turning of the conventional processes, passes through following steps；Go out a clamping head in any one end turnery processing of stud, be machined with cutting groove among clamping head and stud, the shape of clamping head can homalocephalus, cylinder, triangle, tetragonal body, polygon, annular knurl, as long as can guarantee that clamping is stablized；The size of clamping head can be consistent with product size, and size does not do Compulsory Feature.It is 10MM that the length of the clamping head is most short.
Description
Technical field
This patent is related to the manufacturing field of civil engine special construction stud, belongs to a kind of processing technology side
Case.
Background technology
Stud with keyway on a kind of screw thread, the part have the particularity that keyway is processed on the screw thread of stud, do not allow
Secondary rolled screw thread.Therefore conventional stud processing method turning → grinding → rolled thread → milling → mistake screw thread → deburring
→ turning → cleaning → timeliness → sandblasting → cleaning → fluorescent penetrating inspection → cleaning → middle inspection → metal lographic examination → mechanical test
→ final inspection in conventional machining, when crossing screw thread, since retaining part is on screw thread, often crushes screw thread, product is caused not conform to
Lattice.
It needs to design a set of new processing method for the stud feature, suitable for the processing of the part, ensures to close
Lattice rate and the requirement of the technology of part.
Invention content
The characteristics of for the part, design improve following main process flow：
Turning (1) → turning (2) → grinding → rolled thread → milling → mistake screw thread → deburring → turning (3) → cleaning
→ timeliness → sandblasting → cleaning (1) → fluorescent penetrating inspection → cleaning (2) → middle inspection → metal lographic examination → mechanical test → final inspection
Technical solution
Product is the stud of a full thread, has keyway on screw thread, innovative point is：Increase turning process, process
Content be：Go out a clamping head in any one end turnery processing of stud, cutting groove is machined among clamping head and stud, press from both sides
Hold head shape can homalocephalus, can cylinder, can triangle, can tetragonal body, can polygon, can annular knurl, as long as can guarantee the stabilization of clamping.
The size of clamping head can be consistent with product size, and size does not do Compulsory Feature, and the most short length of clamping head is 10MM.
Special construction stud does not carry out turning (2) process in conventional machining, lacks auxiliary clamping part, crosses screw thread
Process can only clamp the threaded portion of stud, and a large amount of burrs being adhered in thread groove generated in milling, remove flash removed
Need larger chucking power, it is easy to crush screw thread, cause special construction stud unqualified.
By improving processing process and processing method, special construction stud processing efficiency and qualification rate is made to carry significantly
Height in processing process other than the processing process comprising conventional stud, improves and processes the special construction stud
Processing scheme, is the emphasis and bright spot of the innovation of this process program, and concrete analysis is as follows：
Turning (2)
As shown in Figure 2, groove left end (long end) is part portion to turning shape, and groove right end (short end) is processing part
Required auxiliary clamping part.The conventional no auxiliary clamping part of processing, part are subsequently ground, and part portion reaches
Required roughness, fenestra has good roughness outside auxiliary clamping part, clamps auxiliary clamping part in clamping, made
Clamping precision is very high during screw thread, threaded portion can not be crushed and effectively remove be adhered to during milling it is a large amount of on screw thread
Burr.
Cross screw thread
As shown in Figure 3, crossing screw thread will be after rolled thread, in order to avoid crushing threaded portion, 3 left end of clamping attached drawing
Auxiliary clamping part carried out screw thread, realized the protection to part.It has crossed after screw thread from groove cut-out, and has ensured part ruler
Very little requirement.In addition, design screw die carried out screw thread, it is intact not only to have protected impulse- free robustness partial threads, but also effectively removes because of milling key
The a large amount of burrs generated on screw thread during slot so as to reach processing request, ensure product quality, improve production efficiency.
The processing process have been subjected to practice processing, examine technological process flow correctness and product quality it is complete
U.S.'s property.This, which is improved, solves the problems, such as clamping in process and a large amount of Burr Problem is generated on screw thread because processing keyway,
It is the process program designed for the particularity of the structural series stud, ensure that the qualification rate of part and technology requirement, improve
Processing efficiency.
Description of the drawings：
Fig. 1 is the stud figure of full thread
Fig. 2 is turning shape graph
Fig. 3 was screw thread clamping attached drawing
Specific embodiment：1st, processing length 10mm, the stud of screw thread M8, the diameter Φ 4mm- Φ of cutting groove
5mm, cut-out well width 3-5mm.Clamping head length 10mm, the size of clamping head are consistent with product grinding process size.
2nd, processing length 20mm, the stud of screw thread M8, diameter Φ 5mm- Φ 5.5mm, the cutting groove of cutting groove
Width 3-5mm.Clamping head length 12mm, the size of clamping head are consistent with product grinding process size.
3rd, processing length 10mm, the stud of screw thread M16, diameter Φ 10mm- Φ 12mm, the cutting groove of cutting groove
Width 5-7mm.Clamping head length 16mm, the size of clamping head are consistent with product grinding process size.
4th, processing length 20mm, the stud of screw thread M16, diameter Φ 10mm- Φ 12mm, the cutting groove of cutting groove
Width 5-7mm.Clamping head length 18mm, the size of clamping head are consistent with product grinding process size.
Claims (2)
1. a kind of full thread processing method with keyway, including conventional processes, it is characterised in that：In the turning of the conventional processes
