Abstract
The invention relates to a novel intermediate-high frequency quenching machine tool of a numerical-control lead screw ball track. A workpiece is clamped by a chuck and held by an elastic tip; an upper stepping motor drives the workpiece to rotate through a screw pair, an active hanging gear, an inertial hanging gear, a driven hanging gear, the chuck and a roller; and meanwhile, the screw pair, a bed saddle, an bed saddle upper sliding plate, a compensation frame and an intermediate frequency transformer drive an induction coil to do linear motion so as to realize the quenching of the induction coil on the workpiece along the roller. The elongation amount of the workpiece is transmitted into an optical grating scale through the elastic tip; and meanwhile, an elongation signal is transmitted into a digital display instrument and a machine tool numerical-control system and respectively used for controlling the upper stepping motor and driving the screw pair, the bed saddle, the intermediate frequency transformer, a water spray ring and the induction coil to move through signal conversion, therefore, the control to the quenching speed is realized.
Description
Technical field
The present invention relates to a kind of numerical-control lead screw ball track medium-high frequency quenching machine, particularly a kind of novel numerical control lead screw ball track medium-high frequency quenching machine.Belong to machine tool industry technology field.
Background technology
Screw mandrel is the common part of many electromechanical equipments, in the higher place of some service requirementss, technically often certain requirement is proposed for the mechanical property of screw mandrel, corresponding techniques requires and in order to improve and the needs that improve mechanical property, often need carry out quench treatment to the raceway face of wire rod thread in order to satisfy.Existing the wire rod thread raceway face quenched, generally adopt the method for medium-high frequency electrical induction heating.Ruhmkorff coil mobile in the screw thread track is to be undertaken by the method for standard machinery transmission, but common mechanical transmission is owing to exist certain driving error and mechanical aspects progressive error inevitably, often cause the temper grade inequality, cause the distortion of workpiece.For this reason, on technology, often before quenching, must leave the stock removal after certain quenching.So not only reduced labor productivity, increased the cost of response, sometimes even can cause occurring serious quality accident.
Summary of the invention
In order to overcome the above-mentioned defective that existing lead screw ball track medium-high frequency quenching machine exists, the invention provides a kind of novel numerical control lead screw ball track medium-high frequency quenching machine.
Solving the technical scheme that its technical problem adopts is: workpiece is by the chuck clamping, and withstand with movable center, last stepper-motor by screw pair, initiatively change gear, inertia change gear, from dynamic change gear, chuck, the roller belts part of starting building rotates, simultaneously, screw pair, saddle, saddle upper slide, compensation frame, intermediate frequency transformer drive the ruhmkorff coil moving linearly, realize that ruhmkorff coil quenches at workpiece upper edge raceway.
The elongation of workpiece is passed to the grating chi by movable center, simultaneously, the elongation signal is passed to digital display instrument and machine tool numerical control system, and control stepper-motor respectively by conversion of signals, drive screw pair, saddle, intermediate frequency transformer, water spray ring and ruhmkorff coil motion realize the control to quenching velocity.Simultaneously, drive the motion of power of the assembling unit controller by following stepper-motor, and feed back to machine tool numerical control system, realize the control of quenching power by the circle grating, and then the degree of depth of control quenched case and the workpiece elongation after being heated.
For the hardness of the raceway both sides that guarantee workpiece even substantially, it must be the gap basically identical on ruhmkorff coil and raceway both sides, so the servo-actuated shim mechanism is set, compensation frame and induction coil, intermediate frequency transformer is rigidly fixed to together, and be installed on the saddle slide plate, the guide wheel of compensation frame is stuck in the thread groove of workpiece, when the helical pitch of workpiece is not consistent with the actual lead of ruhmkorff coil, the screw thread side of workpiece forces guide wheel to drive the compensation frame, transformer and ruhmkorff coil fine motion, to eliminate error between the two, guarantee that ruhmkorff coil is consistent with the gap of screw thread raceway both sides.
The invention has the beneficial effects as follows: screw mandrel changes quenching process over to after can being machined directly into the figure paper size, need not leave stock removal before quenching, the operation of carrying out grinding again after quenching, thereby improved the productivity of work, reduce manufacturing cost, simultaneously, the quality of product also improves accordingly greatly.
