Description
Technical field
The present invention relates to machining equipment technical field, is specifically a kind of be used in reinforced straight flute road cage shaft coupling
The numerical-controlled grinder special of countershaft raceway groove shaping.
Background technology
It is straight that the both ends of the jackshaft of reinforced straight flute road cage shaft coupling are designed with some parallel with countershaft axis
Inner sleeve of the raceway groove as two shaft couplings.The section of every raceway groove is ellipse, with shaft coupling corresponding to steel ball there are two to contact
Point, the angle between two contact points have special technical requirements.This kind of workpiece has several different structure types, its typical structure ginseng
See Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8.
The raceway groove at jackshaft both ends is final after quenching heat treatment to complete finishing by grinding.Domestic processing is same at present
Processing technology and technological equipment are substantially in automaticity low general tool mill or spline shaft grinding machine used by class workpiece
On be ground, the cutlery of form grinding is emery wheel, is indexed manually using universal dividing head and simple trimmer manual trim sand
Wheel.The manual indexing accuracy of universal dividing head is low, and manual trim emery wheel is of poor quality, prevents the raceway groove of grinding-shaping from meeting well
Its technical requirements；It is more that key element is adjusted when repairing emery wheel and grinding simultaneously, it is necessary to is manually completed, labor intensity is larger；Furthermore this
The simple process equipment of class is without dustproof facilities, and dust is more when particularly repairing emery wheel, and the work situation of worker is poor.
The content of the invention
To overcome the shortcomings of existing equipment for grinding, goal of the invention of the invention is to provide a kind of numerically control grinder, passes through number
Straight line or the gyration of system drive bistrique, bistrique frame, workbench, indexing mechanism and diamond pen are controlled, grinding is improved to realize
The automaticity of equipment, improve work situation, lift the purpose of raceway groove grinding quality.
To achieve the above object, the technical scheme is that：Digital control system respectively with servomotor one, servomotor
2nd, servomotor three, servomotor four, stepper motor connection, servomotor one are installed on bistrique frame, pass through ball screw one
Driving bistrique moves forward and backward, and realizes the front and rear of digital control system（Z axles）Linear motion；Servomotor two is installed on column, is passed through
Ball screw two drives bistrique frame to move up and down, and realizes the upper and lower of digital control system（Y axles）Linear motion；Servomotor three is installed
In on lathe bed base, table longitudinal movement is driven by ball screw three, realizes the left and right of digital control system（X axles）Straight line is transported
It is dynamic；Servomotor four is connected with indexing mechanism, by the claw chuck and tailstock clamping workpiece being mounted thereon, to realize workpiece
Numerical control scale-division or axial rotation motion；Stepper motor turns round axis connection by reducing gear and dresser, realizes emery wheel
In trimmer diamond pen around gyroaxis gyration, during form truing, before and after bistrique（Z axles）It is offset to certain distance,
Then rotate trimmer diamond pen and carry out form truing, stone surfacing is reached into requirement, it is higher to process
The raceway groove of precision, so as to meet the special shape requirement of workpiece raceway groove；Grinding wheel spindle is directly driven by grinding head motor, drives emery wheel rotation
Turn, there is provided cutting main motion during grinding.
The digital control system drives servomotor to operate by respective driver, servomotor one, servomotor two, watches
Take motor three, servomotor four is four-axle linked system, stepper motor is autonomous system, passes through program controller and remaining four axle and coordinates
Complete programme-control action.
Rolling linear guide is used between the bistrique frame and column, bistrique frame and bistrique, workbench and lathe bed, can be protected
The flexibility and required precision moved between card part.
