The utility model also has some technical characterictics like this:
(1) described guide rail comprises two guide rails with V-type rolling channel;
(2) the mutual cross arrangement of described cylindrical roller is on the guide rail of V-type rolling channel;
(3) described ball-screw comprises ball-screw screw rod, ball screw nut and angular contact ball bearing, the axle head of the output shaft of harmonic speed reducer and ball-screw screw rod connects firmly, ball-screw nut links to each other with the traverse feed platform, ball-screw nut is arranged on the ball-screw screw rod, and angular contact ball bearing is enclosed within on the ball-screw screw rod.
The utility model is just changeing the drive harmonic speed reducer by stepper motor, after the deceleration by harmonic speed reducer, connect ball-screw, the axle head of the output shaft of harmonic speed reducer and the screw rod of ball-screw connects firmly, the nut of ball-screw links to each other with the traverse feed platform, the nut of ball-screw goes forward to move at the screw rod of ball-screw, can realize the horizontal platform feeding of grinding machine by above-mentioned transmission, otherwise, when stepper motor reverses, after above-mentioned rotation, the traverse feed platform retreats, thereby realizes that grinding machine laterally retreats.
Technical characterstic of the present utility model is:
(1) the cross-roller guide pair is adopted in feeding, form by two guide rail, roller cage, cylindrical rollers with V-type rolling channel, mutual cross arrangement is separated by this mechanism by roller cage cylindrical roller is moving reciprocatingly through on two relative V-type rolling channel faces of accurate grinding, the load of all directions be can bear, high accuracy, rectilinear motion stably realized.Rolling frictional resistance is low, good stability; Starting friction power is little, and servo-actuated is good; Contact area is big, and strain is little, and the effective exercise body is many, easily realizes high rigidity, high load capacity motion; Structural design is flexible, and is easy to install.Original structure is a hydrostatic slideway, is not easy to safeguard, than being easier to wearing and tearing.
(2) running part adopts stepper motor to drive the transmission mode that harmonic speed reducer connects ball-screw, power source at transverse feed mechanism is a stepper motor, the rotating speed of its output rotates the deceleration of ratio greatly by harmonic speed reducer, the axle head of the output shaft of harmonic speed reducer and the screw rod of ball-screw connects firmly, the nut of ball-screw links to each other with the traverse feed platform again, like this behind stepper motor joint power supply, by electrical equipment cyclelog control carrying out deciding journey feeding, move the nut of ball-screw front and back on the ball-screw screw rod, thereby realize the feeding of workpiece and withdraw from action.Former mechanism adopts rack-and-pinion to rotate feeding, and feed accuracy is low, does not guarantee processing request.
Continuous development along with science and technology, bearing manufacturing is also in the variation that takes place to make rapid progress, for development in intense market competition, growth, just must be immediately following market, research, observation bearing development trend, make, process the bearing that those market demands are fast, profit is high, our factory is to produce the enterprise of middle-size and small-size bearing in planned economy period.If for many years the outmoded equipment of buying of equipment, financial strain, difficulty such as the cycle is long, in order to solve this difficult problem, we transform on old equipment, reach production, the needed processing request of manufacturing bearing.This lathe can't reach the requirement on machining accuracy of bearing in present stage, the traverse feed precision is inaccurate, make the bearing ring precision instability of processing, the substandard product height, so be badly in need of the mode of the horizontal reciprocating feed of this lathe of improvement, realize accurate feeding, reach the machining accuracy of bearing ring product.
3MZ136 ball bearing internal ditch grinding machine is used to process the raceway of small rolling ball bearing inner ring.It is the fully automatic grinder of batch machining bearing ring.Need owing to produce, in line with the principle of economizing on the use of funds, will transform on the existing equipment basis, for making 3MZ136 ball bearing internal ditch grinding machine, its high-precision performance requirement of real realization improves the bearing products quality, increases output, reduces cost.Further satisfy the processing needs, the full-automatic septal fossula grinding machine of original 3MZ136 is transformed, former lathe laterally back and forth adopts the mekydro rack feed to be difficult to realize accurate feeding, traverse feed partly is to adopt the feeding of armstrong's patent formula, the low low precision scattered error of working (machining) efficiency is big, be difficult to guarantee the requirement of lasso processing precision of products, improved grinding machine, make this machine tool capability obtain expansion, can process two ditch bearing rings, the self-aligning bearing lasso, realize one-machine-multi-function, improved the purposes of this lathe and the level of automation, result of use is more perfect, has saved fund.Break through the conventional design theory, used stepper motor, harmonic gear reducer, ball-screw and line slideway, improved the emery wheel feed precision by transformation.
The improved grinding machine of the utility model has added the cross-roller guide pair, and good stability can be realized high rigidity, high load capacity motion, and machine tool feed is more steady, and it is little to rub, and is not easy wearing and tearing, safeguards easily.By adopting stepper motor, harmonic speed reducer, ball-screw traverse feed mode, can rotate the deceleration of ratio by harmonic speed reducer greatly, can make traverse feed more steady, by electric programme-control stepper motor the traverse feed precision is improved, realize feeding accurately and retreat, make the bearing ring machining accuracy accurate.Also increased simultaneously the stroke of traverse feed, this lathe can only work sheet ditch bearing ring before transforming, and can process the lasso of Shuan Gou and many ditches bearing and increased the traverse feed stroke, thereby realize one-machine-multi-function.The utility model has reduced the cost of buying new equipment, has improved the purposes of lathe.
