Description
Technical field:
The present invention relates to mechanical field, relate in particular to lathe, the particularly lead screw transmission mechanism in lathe, the specifically real-time testing agency of screw mandrel linearity in a kind of lathe.
Background technology:
In lathe, utilize lead screw transmission mechanism that the circular motion of dynamical element is converted into rectilinear motion.When screw mandrel rotates, the nut being arranged on screw mandrel does rectilinear motion.In the situation that screw mandrel length is larger, nut can make the middle part of screw mandrel hanging part sagging, affects linearity and the concentricity of screw mandrel, and affects the machining accuracy of lathe.In prior art, in order to check the linearity of screw mandrel, need to will after screw mandrel dismounting, measure, operating process is comparatively loaded down with trivial details.
Summary of the invention:
The object of the present invention is to provide the real-time testing agency of screw mandrel linearity in a kind of lathe, the real-time testing agency of screw mandrel linearity in described this lathe will solve the loaded down with trivial details technical problem of operating process of measuring screw mandrel linearity in lathe in prior art.
The real-time testing agency of screw mandrel linearity in this lathe of the present invention, comprise machine tool frame, screw mandrel and a flat board, the two ends of screw mandrel are connected with machine tool frame by bearings mechanism respectively, wherein, in described machine tool frame, be fixedly installed a fan-shaped laser beam transmitter, described flat board is relative with machine tool frame fixing, described flat board is parallel to described screw mandrel, described fan-shaped laser beam transmitter and the dull and stereotyped both sides that lay respectively at screw mandrel, screw mandrel and the dull and stereotyped fan-shaped laser projection scope that is all positioned at fan-shaped laser beam transmitter.
Further, in flat board along perpendicular to screw axis to direction be provided with scale.
Further, in flat board along perpendicular to screw axis to direction be arranged at intervals with a plurality of optical sensors, optical sensor described in any one is all connected with a testing circuit plate by holding wire, in described testing circuit plate, be provided with single-chip microcomputer, described single-chip microcomputer is connected with a signal output apparatus, and described signal output apparatus comprises light-emitting component or sounding component.
Operation principle of the present invention is: fan-shaped laser beam transmitter projects visible laser with fan-shaped angle, this visible laser forms straight line in flat board, screw mandrel stop portions visible laser, make the middle part of described straight line produce a breach disconnection, when standard screw mandrel is rotated to one week, the length and location of described breach is marked on flat board.In running order at screw mandrel, detect when the length of breach or position, with respect to mark position, skew occurs, point out the linearity of screw mandrel that variation has occurred.Utilization is arranged on the optical sensor in flat board, the skew with respect to mark position of the length of breach or position can be detected, thereby send cue by testing circuit plate.
The present invention and prior art are compared, and its effect is actively with obvious.The present invention utilizes fan-shaped laser beam transmitter and the dull and stereotyped real-time testing agency of screw mandrel linearity that forms, can judge the situation of change of screw mandrel linearity by detecting the variation of the projection of screw mandrel in fan-shaped laser beam, can in the lathe course of work, detect the variation of screw mandrel linearity in real time, solve the loaded down with trivial details technical problem of operating process of measuring screw mandrel linearity in lathe in prior art.
Brief description of the drawings:
Fig. 1 is the structural representation of the real-time testing agency of screw mandrel linearity in a kind of lathe of the present invention.
