Abstract
The utility model discloses an end surface center for milling and machining a linked shaft spline. The end surface center comprises a hollow shaft and a center shaft installed in an inner hole of the hollow shaft; one end of the center shaft, in the inner hole of the hollow shaft, is in compression joint with one end of a spring; the other end of the spring is in compression joint with an elastic force regulating screw rod which is connected into the inner hole of the hollow shaft in a threaded mode; the conical part of the center shaft extends out of one port of the hollow shaft under the effect of the spring; and the hollow shaft is provided with teeth in the end head of the port. Compared with the prior art, the end surface center for milling and machining the linked shaft spline solves the problems that the existing hydraulic motor linked shaft spline machining difficulty is difficult to ensure, the technology is complex, and the efficiency is low.
Description
Technical field
The utility model relates to machinery manufacturing technology field, especially a kind of used instrument of processing on the cycloid hydraulic motor universal driving shaft of spline.
Background technology
Two universal driving shafts are arranged in the cycloid hydraulic motor; Little universal driving shaft connects the rotation synchronously of valve plate drive rotor and joins oil continuously; Long universal driving shaft connects rotor moment of torsion is exported to output shaft, and the hydraulic motor performance is also mainly leaned on the quality of flow and moment of torsion output function, thereby; The craft precision of universal driving shaft and interior external splines thereof requires quite high, especially very high to the requirement of universal driving shaft spline axiality, radius run-out degree and axial end size.
At present, in order to guarantee machining accuracy, be that axial end car at universal driving shaft goes out the technology shaft part that the spline milling is used to the processing of universal driving shaft spline; After the spline milling finishes again car fall this technology shaft part, the locate mode of universal driving shaft is used scroll chuck clamping universal driving shaft, the tailstock thimble of lathe holds out against the universal driving shaft other end; The locate mode positioning accuracy on this " folder one top " is lower; When for example the minimum jerk value of scroll chuck is 0.05 millimeter, cannot say for sure to demonstrate,prove the axial precision that 0.02 millimeter of universal driving shaft spline is thought, and increase the technology shaft part of universal driving shaft termination; Except working (machining) efficiency is low, the material cost and the processing cost of the universal driving shaft that has also improved.
Summary of the invention
It is top with end face that the utility model problem to be solved provides a kind of universal driving shaft spline Milling Process, is difficult to guarantee complex process, inefficient problem to solve existing hydraulic motor universal driving shaft spline machining accuracy.
In order to address the above problem; This universal driving shaft spline Milling Process is top with end face; Include hollow shaft and be installed in the tail spindle in the said hollow shaft endoporus; The end of said tail spindle in said hollow shaft endoporus is crimped with an end of spring, is crimped with through being threaded in the elastic force adjusting screw(rod) in the said hollow shaft endoporus at the other end of this spring; Said tail spindle its conus portion under the effect of said spring stretches out outside the port of said hollow shaft, and said hollow shaft is provided with tooth in the termination of this port.
In the technique scheme, more concrete scheme can be: the outside of said hollow shaft is provided with the ring flange that is used to install dividing head.
Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, the top design of end face is put workpiece and held out against with tailstock, can make the direct positioning and clamping of workpiece, and is convenient to operation, and working (machining) efficiency is high;
2, the top top and lathe afterbody axle top top tight workpiece of end face; The top end face part top tight workpiece of end face replaces scroll chuck clamping work pieces of the prior art to do axial rotation; The use that end face is top, the universal driving shaft locate mode has changed " two push up, stir " into by " folder one top " of prior art, therefore; End face is top higher with axiality tail spindle, has guaranteed the axial precision of spline processing; Because top jerk value guarantees in 0.02 millimeter; And the jerk value minimum of scroll chuck can only arrive 0.05 millimeter, and the tooth engagement of opening on the top tooth with the top end face of end face of end face and the workpiece has not only guaranteed the axial precision of spline processing but also guaranteed the radial accuracy that spline is processed; The top axial end of end face has guaranteed that partly splined shaft is to size stability.
Description of drawings
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the left view of the utility model embodiment;
Fig. 3 is an A place enlarged drawing among Fig. 1.
The specific embodiment
Implement the utility model is done further to detail below in conjunction with accompanying drawing:
Fig. 1, Fig. 2, universal driving shaft spline Milling Process shown in Figure 3 are made up of hollow shaft 1, tail spindle 2, spring 3, bolt 4, ring flange 5 etc. with end face is top.Be installed in the tail spindle 2 in hollow shaft 1 endoporus, the end of tail spindle 2 in hollow shaft 1 endoporus is crimped with an end of spring 3, is crimped with through being threaded in the elastic force adjusting screw(rod) 4 in hollow shaft 1 endoporus at the other end of this spring 3; Tail spindle 2 its conus portion under the effect of spring 3 stretches out outside the port of hollow shaft 1, and hollow shaft 1 is provided with tooth in the termination of this port.The outside of hollow shaft 1 is provided with the ring flange 5 that is used to install dividing head.Tail spindle 2 and lathe afterbody axle top top tight workpiece that end face is top, the tooth of opening on the tooth of the end face part of hollow shaft 1 and workpiece engagement and drive workpiece axially rotate, and have guaranteed the axial precision of spline processing; Because top jerk value guarantees that in 0.02 millimeter the tooth engagement of opening on the tooth of hollow shaft 2 end faces and the workpiece has also guaranteed the radial accuracy of spline processing; The axial end of the top hollow shaft 1 of end face has guaranteed that partly splined shaft is to size stability.
