Abstract
The invention relates to a grooving technology, in particular to a grooving technology for a flange half shaft. According to the grooving technology, firstly, a spline is milled on the flange half shaft, then induction hardening heat treatment is performed, and finally a clamping ring groove is obtained through grooving. After the induction hardening heat treatment is performed, the surface hardness of the spline on the flange half shaft reaches HRC52 or higher than HRC52. A CBN grooving tool is adopted for grooving the spline of the flange half shaft. By the adoption of the method, according to the grooving technology for the flange half shaft, firstly, the spline is milled, then the induction hardening heat treatment is performed, and finally the clamping ring groove is obtained through grooving; the machining sequence can avoid that the clamping ring groove is affected by heat treatment deforming, and the influences of the heat treatment deforming are the critical defects of a traditional machining method. The machining precision of the clamping ring groove in spline of the flange half shaft can be greatly improved.
Description
Technical field
The present invention relates to a kind of technics of slot, particularly a kind of flange semiaxis technics of slot.
Background technology
On flange semiaxis truck back axle, bear the vital part of heavy load, require to withstand shocks alternate load, condition of work is very severe, so require flange semiaxis to have good mechanical performance.On some heavy-load automobile and tractor, can use planetary gear type hub reduction gear, this decelerator has different organization plans, wherein a kind of structure be flange semiaxis and planet carrier by spline joint, and realize axial location by the annular groove on spline.The present invention be directed to the processing method of annular groove in this flange Formation of Axle Shaft Spline, traditional method is first to process annular groove, milling spline again, then carry out impewdance matching, the topmost advantage of this method is that the cost of grooving operation is low, but topmost shortcoming is, flange semiaxis impewdance matching case depth is deep, after impewdance matching, thermal deformation is large, be finally difficult to guarantee shape and the dimensional accuracy of final annular groove, and this shortcoming is fatal.
Prior art is a kind of has the output shaft processing technology main technique route of specific cards annular groove as follows: rolling spline and screw thread, then rough lumber annular groove, follows carburizing and quenching, last fine finishining.Same last carburizing and quenching, thermal deformation is large like this, is difficult to guarantee shape and the dimensional accuracy of final annular groove.
Summary of the invention
The technical issues that need to address of the present invention are to provide the flange semiaxis technics of slot that a kind of annular groove form and dimensional precision is high.
For solving above-mentioned technical problem, a kind of flange semiaxis technics of slot of the present invention first mills out spline on flange semiaxis, then carries out impewdance matching heat treatment, finally cuts annular groove; Described flange semiaxis upper spline part is after impewdance matching heat treatment, more than case hardness reaches HRC52; For grooving in flange Formation of Axle Shaft Spline part, adopt CBN grooving cutter.
Further, described CBN grooving cutter for inlaying a CBN point of a knife matching with annular groove width dimensions on the ordinary rigid alloy grooving mountain of swords.
Further, described splined section length accuracy is ± 0.1mm that described annular groove width accuracy is ± 0.08mm.
Adopt after said method, the first milling spline of flange semiaxis technics of slot of the present invention, impewdance matching again, finally cut annular groove; Such processing sequence can avoid annular groove to be subject to the impact of heat treatment deformation, and the impact of this heat treatment deformation is the fatal shortcoming of traditional diamond-making technique.The present invention can improve the machining accuracy of annular groove in flange Formation of Axle Shaft Spline greatly.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of flange semiaxis grooving of the present invention.
Fig. 2 a is the structural representation of grooving cutter in prior art.
Fig. 2 b adopts the structural representation of CBN grooving cutter in technique of the present invention.
In figure: 1 is flange semiaxis, 2 is spline, and 3 is grooving cutter, and 4 is CBN point of a knife.
The specific embodiment
As shown in Figure 1, a kind of flange semiaxis technics of slot of the present invention first mills out spline 2 on flange semiaxis 1, then carries out impewdance matching heat treatment, finally cuts annular groove.New processing method can avoid annular groove to be subject to the impact of heat treatment deformation, and the impact of this heat treatment deformation is the fatal shortcoming of traditional diamond-making technique.But, new processing method faces two difficult points, and one is that grooving belongs to interrupted turning on spline, because the key tooth on spline and teeth groove are alternatively distributed, and splined section is through impewdance matching processing, more than case hardness reaches HRC52.
Because the hard alloy cutter of general standard is difficult to overcome, do not process often several cutters and be just damaged, and special grooving cutter has well solved this problem.Be common hard alloy cutter as shown in Figure 2 a, the special cutter that the present invention shown in Fig. 2 b adopts is CBN cutter, is on the ordinary rigid alloy grooving mountain of swords, to inlay a CBN point of a knife matching with annular groove width dimensions.
As shown in Figure 1, splined section length of the present invention is B, and annular groove width is A; Described splined section length is controlled as B ± 0.1mm, and described annular groove width is controlled as A ± 0.08mm.
Although more than described the specific embodiment of the present invention; but those skilled in the art are to be understood that; these only illustrate; can make various changes or modifications to present embodiment; and not deviating from principle of the present invention and essence, protection scope of the present invention is only limited by appended claims.
