Description
The utility model relates to lathe, and especially a kind of wheel that applies in the rolling stock manufacturing removes the heavy-duty machine bed to the numerical control transient equilibrium.
In rolling stock was made, taking turns right dynamic balancing measurement and going heavily was the twice critical processes.At present used all is that going after transient equilibrium and the measurement carried out on two equipment heavily respectively, specific practice is behind the right unbalancing value of measuring wheel on the dynamic balancing machine, wheel is pruned heavily to being transported to the enterprising driving of lathe, go weight by claiming iron filings weight, go heavy scope to carry out according to operator's experience, after going heavily to finish, need transport to the dynamic balancing machine detection of getting on again, heavily forbidden also need transport reface back if go, so repeatedly, till reaching requirement, so not only go heavy difficulty of processing big, efficient is low, and can't reach the requirement of accurate removal amount of unbalance.In addition, existing used transient equilibrium driving wheel is to revolving multipurpose universal joint pattern, and drive unit and wheel are to can't throwing off when carrying out dynamic balancing measurement for wheel, and wheel is not to being in free state but adding under the state of interference and measure, thereby the precision of measuring is low.
The purpose of this utility model just provides takes turns right dynamic balancing measurement and removes heavy cut, measures accurately a kind of the collection, goes the high wheel of heavy precision that the heavy-duty machine bed is removed in the numerical control transient equilibrium.
The purpose of this utility model is adopted realization by following technical scheme:
Wheel goes the heavy-duty machine bed to adopt horizontal layout to the numerical control transient equilibrium, divides dynamic balancing measurement and removes heavy cut two parts, comprises lathe bed and wing base etc., and wing base is installed in the rear of lathe bed.Lathe bed is provided with the numerical control operation panel, and the two ends of lathe bed are driving box and driven headstock, and driven headstock can move along lathe bed, be provided with drive shaft in the driving box, be provided with slave spindle in the driven headstock, it is top that end, two main shaft opposite ends all is equipped with the center, and the drive shaft end also is provided with straight end-face key.Two symmetrical transient equilibrium rockers are located between driving box and the driven headstock, hydrostatic bearing pad is housed on the rocker, the transient equilibrium rocker can move along lathe bed, the middle part of lathe bed is liftable carriage, between carriage and transient equilibrium rocker, be provided with fraction wheel drive device, fraction wheel drive device is by the two symmetrical groups friction pulley, fork, elevating lever, motor, driving-belt constitutes, fork one end is fixed, the other end links to each other with friction pulley, and elevating lever one end is fixed, and the other end is fixed on the fork, the lifting of elevating lever makes fork swing around stiff end, friction pulley also is provided with brake gear by driving-belt and motor-driven at the axis of symmetry place of fraction wheel drive device, and fraction wheel drive device and brake gear all can move to be adapted to different workpiece (wheel to) along lathe bed.Be equipped with the numerical control cross slid platform on the wing base, be respectively applied for wheel revolver and right wheel are gone to a heavy left side, right cutting head symmetry back-to-back is installed on the cross slid platform, all is equipped with bite on left cutting head and the right cutting head.
The principle of work of the numerical control transient equilibrium being removed the heavy-duty machine bed of taking turns of the present utility model:
The wheel of earlier will be to be measured and going heavily to process is to being placed on the carriage of having stretched, and by the carriage holder and takes turns slow decline.To take turns on the hydrostatic bearing pad that is placed on the transient equilibrium rocker, adopt the friction pulley driving wheel that the tread of two wheels is realized right the rotatablely moving of wheel during dynamic balancing measurement, the rotation of friction pulley is passed through the driving-belt transmission by motor respectively, motor adopts variable-frequence governor control speed change and uniformly accelerated motion, friction pulley can be thrown off automatically when reaching the required rotating speed of dynamic balancing measurement, makes wheel to testing under the free rotation state of the minimum hydrostatic support of friction force fully on the transient equilibrium rocker.After test finishes and since the dynamic balancing measurement hour wheel to free rotating speed more than 200rpm, for saving time and safety, can make wheel to stopping operating by the brake gear under the two right wheel treads of wheel.Wheel is to after finishing dynamic balancing measurement, the main shaft of driving box and driven headstock stretches out, to take turns jack-up wheel shaft two ends center pit at wheel by two central term pinnacles on it, break away from the dynamic balancing measurement rocker, straight end-face key in the driving box on the drive shaft be installed in the driving-disc of wheel and connect wheel shaft one end, drive shaft rotating band driving wheel is to cutting heavy rotatablely moving, and the slave spindle in the driven headstock is then done passive rotation by wheel to drive.Left side in the lathe on the cross slid platform, right cutting head is respectively applied for wheel going heavily revolver and right wheel, numerical control cross slid platform vertically (being parallel to wheel to axis) motion moves to the left side of wheel to being cut with cutting head, right wheel inboard, laterally (heavy directly in taking turns axis) provides F.F., the motion that the worker advances, two cutting head are not worked simultaneously.
The of the present utility model wheel goes the heavy-duty machine bed to have the following advantages to the numerical control transient equilibrium:
(1) taking turns right dynamic balancing measurement and going heavy cut to concentrate on the equipment and finish, compact conformation has reduced wheel to round transport process and parking space, and floor area reduces greatly, and lathe efficient improves greatly simultaneously;
Adopt the friction pulley driving wheel that the tread of two wheels is realized right the rotatablely moving of wheel during (2) owing to dynamic balancing measurement, friction pulley breaks away from wheel tread during measurement, wheel is frictionally rotated freely be similar to nothing under hydrostatic support, so measurement result is accurate;
(3) go heavy cut by the reliable digital control system control of advanced person, remove heavily accuracy height, the process full automation.
Below in conjunction with accompanying drawing the utility model is elaborated.
