Abstract
The utility model belongs to the technical field of machinery, and in particular relates to a spline housing precision forging part. The spline housing precision forging part comprises a cylindrical spline housing body, wherein a round hole penetrating through upper and lower end faces of the spline housing body is formed in the spline housing body; a circular ring is arranged in the middle of the spline housing body, and a ring slot is formed in the middle of the circular ring surface; four extension points are formed in the ring slot, and the ring slot on the four extension points extends toward upper and lower end faces of the circular ring to form vertical through slots. Optimally, the four extension points are positioned on corners of the inscribed square of the ring slot; the spline housing body at the upper side of the circular ring is a step shaft optimally; optimally, a bulge is molded upward on the half ring surface of the upper end face of the spline housing body. The spline housing precision forging part is simple in structure, safe and reliable and good in practicality.
Description
Technical field
The utility model belongs to field of mechanical technique, is specifically related to a kind of spline housing fine forge piece.
Background technique
Spline housing and splined shaft mix proportion splined, be a kind of conventional kind of drive, and the processing to spline housing in traditional industrial production normally adopts line to cut the method for electric machining.This processing method used time is longer, and manufacturing efficiency is lower.Manufacturing firm all adopts precision forging blank technology both at home and abroad at present, can meet required precision like this, has reduced again manufacture cost and cycle, also meets the trend of world today's development of manufacturing simultaneously.
Summary of the invention
In order to overcome above shortcomings part in prior art, it is a kind of simple in structure, safe and reliable that the purpose of this utility model is to provide, and cost is lower, and practicability is good, the spline housing fine forge piece of easily accepting for market.
In order to reach above-mentioned object, the utility model adopts following concrete technological scheme:
A kind of spline housing fine forge piece, comprise columned spline housing body, on spline housing body, be provided with the circular hole that connects spline housing body upper and lower end face, the middle part of spline housing body is provided with annulus, the middle part of annulus anchor ring is provided with annular groove, on described annular groove, be provided with four and extend points, four annular grooves that extend some place all upwards the upper and lower end face of annulus extend to form vertical groove.
Preferably, four described extension points are positioned on the foursquare angle of connecing of annular groove.
Preferably, the spline housing body of described annulus upside is Step Shaft.
Preferably, 1/2nd anchor rings of described spline housing body upper-end surface upwards form projection.
Compared with prior art, the utlity model has following outstanding advantages and effect:
Of the present utility model simple in structure, safe and reliable, practicability is good.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of spline housing fine forge piece, comprise columned spline housing body 7, on spline housing body 7, be provided with the circular hole 1 that connects spline housing body upper and lower end face, the middle part of spline housing body 7 is provided with annulus 6, the middle part of annulus 6 anchor rings is provided with annular groove 9, on described annular groove 9, be provided with four and extend points, four annular grooves that extend some place all upwards the upper and lower end face of annulus extend to form vertical groove 8.
Preferably, four described extension points are positioned on the foursquare angle of connecing of annular groove 9.
Preferably, the spline housing body of described annulus 6 upsides is Step Shaft (upper axle 3 and axis 5 is excessive by step surface 4).
Preferably, 1/2nd anchor rings of described spline housing body upper-end surface 2 upwards form projection 21.
Finally it should be noted that: above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
