Description
Technical Field
The invention relates to the technical field of spline housing processing, in particular to a clamp for processing an excircle of a spline housing.
Background
The spline housing and the spline shaft are used for transmitting mechanical torque, and the spline connection is composed of an internal spline and an external spline. The inner spline and the outer spline are both multi-tooth parts, the spline on the inner cylindrical surface is an inner spline, and the spline on the outer cylindrical surface is an outer spline. Thus, the spline housing is actually an internal spline and the spline shaft is an external spline. The spline connection can be divided into two types of rectangular splines and involute splines according to different tooth shapes, and the two types of splines are standardized. The spline coupling is suitable for couplings with high centering accuracy requirements, large transmission torque or frequent slippage.
The spline housing processing process is that firstly pulling the internal spline, then turning the excircle, and the excircle turning process needs to place the spline housing on the spline mandrel, and manually carries to equipment for processing. The existing spline mandrel adopts solid bar materials to process splines, the weight of the mandrel can reach 13kg, in addition, the weight of parts can reach 25kg, and the labor intensity of workers is high. Simultaneously spline dabber adopts the flank centering, draws spline process spline broach wearing and tearing back, strides the stick pitch size change, can influence spline dabber positioning accuracy to lead to spline housing excircle processing to beat the increase.
Therefore, a fixture for processing the excircle of the spline sleeve is needed to solve the technical problems.

Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1, 2, 3, 4 and 5, the fixture for processing the excircle of the spline sleeve comprises a positioning seat 1 and a spline mandrel 5, wherein a taper hole 2 is formed in the positioning seat 1, a tapered boss 6 is arranged at one end of the spline mandrel 5, the tapered boss 6 is inserted into the taper hole 2 during installation, and the taper of the taper hole 2 is the same as that of the tapered boss 6, so that coaxial positioning is facilitated.
Four threaded holes 4 are formed in the positioning seat 1, the four threaded holes 4 are arranged at equal angles, four second bolt holes 7 are formed in the spline mandrel 5, the threaded holes 4 correspond to the second bolt holes 7 one to one, and the positioning seat 1 and the spline mandrel 5 are fixedly connected together by inserting bolts into the threaded holes 4 and the second bolt holes 7. The central axes of the spline mandrel 5, the taper hole 2 and the taper boss 6 are all positioned on the same straight line. Be provided with three first bolt hole 3 on the positioning seat 1, the equiangular arrangement between three first bolt hole 3 penetrates first bolt hole 3 through the bolt and inserts the threaded hole of processing equipment, fixes positioning seat 1 on the processing equipment. The spline mandrel 5 is internally provided with a cavity 8, and the cavity 8 is cylindrical and suitable for reducing weight. The central axis of the cavity 8 and the central axis of the spline mandrel 5 are positioned on the same straight line.
When the spline mandrel is used, the positioning seat 1 is fixed on processing equipment, the spline mandrel 5 is fixed on the positioning seat 1 through a bolt, the spline sleeve 9 to be processed is sleeved outside the spline mandrel 5, and the spline sleeve 9 and the spline mandrel 5 can be ensured to be coaxial. The structure is matched with a conical surface and can be quickly replaced. Need not artifical transport dabber during processing part, change original sectional type spline structure into hollow structure simultaneously, reduce anchor clamps self weight to with spline flank centering change the big footpath of spline centering, utilize the big footpath of spline centering reducible spline fit clearance, the part spline strides the stick apart from the size can not influence anchor clamps clamping precision.
