Abstract
The invention provides automobile steering pump motor shaft end surface processing equipment, which comprises a grinding wheel, wherein the grinding wheel is connected with driving equipment; the driving equipment drives the grinding wheel to rotate; the outer edge of the friction surface of the grinding wheel is provided with an arc-shaped friction groove; one side of the grinding wheel is provided with a motor shaft driving device for driving the motor shaft to rotate. According to the automobile steering pump motor shaft end surface processing equipment, the outer edge of the friction surface of the grinding wheel is provided with the arc-shaped friction groove, and the end surface of the motor shaft is polished by the arc-shaped friction groove so as to form a spherical surface on the end surface of the motor shaft. The method for processing the spherical surface of the motor shaft in a grinding wheel polishing mode is simple and has the advantages of high processing speed and high production efficiency, and the automated production requirement can be effectively satisfied.
Description
Technical field
The present invention relates to steering pump of automobile motor shaft production field, the process equipment that particularly relates to a kind of processing method for steering pump of automobile sealing of motor spindle end face and realize the method.
Background technology
Automobile steering system mainly comprises steering wheel, power shaft, torque arm and power steering hydraulic system.The power steering valve of power steering hydraulic system comprises valve pocket and valve two parts, on valve pocket and spool, is equipped with oilhole, and the oilhole of valve pocket and diverse location on spool is interconnected and can forms the different closed circuit of flow direction.Steering wheel is connected with torque arm by power shaft, and the other end of torque arm is connected with spool.When rotating steering wheel, moment of torsion is passed to torque arm by power shaft, torque arm drives Spool rotating, make spool and valve pocket generation relative motion, will change like this break-make relation of oil duct between valve pocket and spool and the flow direction of hydraulic oil, and then rotate towards different directions by hydraulic gear band motor car wheel.The hydraulic oil of power steering hydraulic system is provided by motor turning electrical machinery hydraulic pump group, steer motor hydraulic pump group comprises motor, hydraulic pump and oil tank three parts, oil tank and motor link into an integrated entity by connector, hydraulic pump is placed in oil tank, the motor shaft of motor is directly connected with hydraulic pump through connector mesopore, and motor and hydraulic pump share a motor shaft.Because this motor shaft is that motor and hydraulic pump share, therefore the crudy of motor shaft is had relatively high expectations.
The end face sphere of motor shaft one end of automobile steering system, the processing for sphere at present mainly adopts the mode of milling to process.Because the diameter of motor shaft own is less, adopt the spherical end surface technique of milling mode processing motor shaft comparatively complicated, process velocity is slow, and production efficiency is low, does not therefore meet the needs of automated production.
Summary of the invention
The shortcoming of prior art, the object of the present invention is to provide the steering pump of automobile motor shaft end method for processing surface that a kind of processing technology is simple, process velocity is fast, production efficiency is high in view of the above.
For achieving the above object and other relevant objects, the invention provides a kind of steering pump of automobile motor shaft end method for processing surface, it comprises the steps: first to arrange an emery wheel, outward flange at emery wheel rubbing surface arranges an arc frictional groove, and the radian of described arc frictional groove is consistent with the radian that will process motor shaft spherical end surface; By drive unit, drive emery wheel and motor shaft to rotate, with the arc frictional groove of emery wheel, the end face of motor shaft is polished, make the end face of motor shaft form spherical end surface.
The invention also discloses a kind of process equipment of realizing above-mentioned steering pump of automobile motor shaft end method for processing surface, it comprises an emery wheel, described emery wheel is connected with a driving arrangement, described driving arrangement drives described emery wheel rotation, the rubbing surface outward flange of described emery wheel arranges an arc frictional groove, and a side of described emery wheel is provided with the motor shaft drive unit of a drive motors axle rotation.
Preferably, described motor shaft drive unit comprises the first carrying roller, the second carrying roller being arranged in parallel, and described the first carrying roller, the second carrying roller are connected with drive motors by transmission mechanism, and described the first carrying roller, the second carrying roller top are provided with a pinch roller.
Preferably, described the first carrying roller, the second carrying roller are connected with described drive motors by driving belt respectively.
Preferably, the radian of described arc frictional groove is 90 °.
As mentioned above, steering pump of automobile motor shaft end method for processing surface of the present invention and process equipment have following beneficial effect: this steering pump of automobile motor shaft end method for processing surface arranges arc frictional groove on the outward flange of emery wheel rubbing surface, use this arc frictional groove to polish to the end face of motor shaft, and then form spherical at the end face of motor shaft.Adopt the mode of this grinder buffing to process the spherical method of motor shaft simple, process velocity is fast, and production efficiency is high, can effectively meet the needs of automated production.
