Description

Ball screw assembly, moment of friction measuring instrument
Technical field:
The utility model relates to a kind of ball screw assembly, moment of friction measuring instrument, and being used to measure ball screw assembly, does not have in that preload is arranged under the external load effect, and ball nut and ball-screw are relative to rotating required moment continuously.
Background technology:
Ball screw assembly, is the critical component during numerically-controlled machine is produced, its good and bad performance that directly influences numerically-controlled machine; Moment of friction is the ball screw assembly, that preload is arranged, under no external load effect, ball nut and ball-screw are relative to rotating required moment continuously, its index is the important indicator that influences the ball screw assembly, performance, it directly influences the bearing accuracy of product, transmission efficiency, kinetic stability, the feel fluency, reliability, temperature rise, noise, rigidity, serviceable life etc., the ball screw assembly, of China's production at present, moment of friction measurement means imperfection, though also made ball screw assembly, moment of friction measuring instrument, adopts pressure sensor, LOAD CELLS is measured, install cumbersome, can bring measuring error, and 100rpm carries out by the national standard measuring speed, can not well reflect the Changing Pattern of moment of friction under low speed and the little feeding state in this state, does not also reflect the Changing Pattern of leading screw one-period inner friction torque simultaneously, measurement sensitivity is low, and some problem can not effectively reflect.
Summary of the invention:
The purpose of this utility model provides a kind of ball screw assembly, moment of friction measuring instrument, and solving ball screw assembly, does not have in that preload is arranged under the external load effect, and ball nut is difficult to measure problem accurately with ball-screw relative to rotating required moment continuously.
The purpose of this utility model realizes as follows: it relates to drive control box, computerized test assembly and mechanical actuation device, mechanical actuation device be on base before the line spread axle bed, shaft coupling, torque sensor, back axle bed and tailstock, there is rotating shaft at preceding axle bed, torque sensor, axle bed middle part, back, tailstock has tail spindle, the rotating shaft two ends of torque sensor are connected with the rotating shaft power of preceding axle bed with the back axle bed by shaft coupling respectively, have motor power to be connected in the rotating shaft of preceding axle bed; Clamping ball-screw between the rotating shaft of back axle bed and the tailstock centre axle; The signal wire of torque sensor and motor power line are electrically connected with drive control box, and drive control box is electrically connected with computerized test assembly.During measurement, the motor rotary power through preceding axle bed rotating shaft, torque sensor rotating shaft, after the axle bed rotating shaft pass to leading screw, the moment of friction of lead screw pair reflects by the torque sensor rotating shaft, i.e. this rotating shaft is as the strain transducer axle, and measurement data hands over computerized test assembly to handle through drive control box.
Torque sensor is the electronic torque coupling sensor, device resistance-strain bridge on the strain transducer axle.
Owing to adopt the electronic torque coupling sensor, the moment of torsion that friction force between ball-screw and the nut is caused passes to the strain transducer axle dexterously, make it produce micro-deformation, this trace signal is amplified by the high-precision meter amplifier, is transformed into the square-wave signal that is directly proportional with twisting strain through the V/F converter again.After electric processing, produce corresponding with it electric signal, transmit the signal to secondary instrument, the dynamic value that shows moment of friction during secondary instrument on the spot, Dynamic Signal with moment of friction transmits computing machine simultaneously, and measurement result is real-time display error curve on computer screen, measures the end back and by GB/T 17587-1998 (eqvISO 3408-1992) data processing is carried out in the definition of every error by computing machine, form standard compliant examining report, deposit or printout.
This measuring instrument can be realized the measurement to the ball screw assembly, moment of friction, can show locked rotor torque numerical value, can show dynamic force moment numerical value again, the examining report of comparison standard can be provided, store, search, compare conveniently, help the improvement of ball screw assembly, performance; Instrument also can show speed revolution value, shows the moment of friction peak value; This accuracy of instrument height, good stability, the inferred-zero drift, antijamming capability is strong, can transmit positive and negative torque signals continuously.Can promote the ball screw assembly, detection level, for manufacturing enterprise brings good economic benefit and social benefit.
