2.2.1 what is ball lever appearance
Appearance of lever of ball of QC10 of Lei Ni carry on is to be used at numerical control machine tool precision of two axes linkage detects quickly a kind of tool that analyses with machine tool breakdown. It is formed in the sensor of high accuracy displacement inside stretch fiber lever by one installation, this sensor includes two coil mix portable inside lever, its job principle kind with at using the displacement sensor of LVDT technology. When its length varies, inside lever is immigrant coil, inductance happening changes, detect change of signal of circuit general inductance is 0.1μm displacement signal into resolution, pass into a PC through interface. Interferometer of laser of its precision classics detects amount to ±0.5μm(to be in 20 ℃ ) .
Press when the machine tool when booking a program to go round for radius with length of ball lever appearance, QC10 sensor detects the change of direction of radius of machine tool motion, QC10 of Lei Ni carry on analyses software but rapid if the scale of the linearity the machine tool, verticality, repeatability, backlash, each axis is denied match the depart in reaching servo function to wait for the change from radius to come out.
2.2.2 main functions
(1) the fast demarcate of machine tool accuracy class detects through ball lever instrument is being used below different feed speed machine tool, the feed speed that makes handlers can choose precision of contented treatment workpiece to ask undertakes machining, avoided the generation of reject thereby.
(2) diagnose of machine tool breakdown and problem quickly with the analysis ball lever appearance can be found out quickly and problem of analytic machine tool is in, basically can check retrorse difference, guide screw carries unoccupied place difference on the back, servo gain does not match, the function such as error of verticality error, filar lever cycle, for example machine tool produces postaccident hitting a car, appearance of usable ball lever detects and tell handlers machine tool precision to the state is reached quickly whether can continue to use. Already stipulated in ISO standard appearance of the lever that use a ball detects the method of machine tool precision.
(3) of convenient machine tool maintain with safeguard ball lever appearance to be able to tell precision of user machine tool metabolic circumstance, can remind maintenance the engineer notes the problem of the machine tool so, undertake preventive safeguard, do not send lead to big trouble.
(4) shorten development cycle of new machine tool detects with ball lever appearance can divide separate out machine tool lubricant system, servo, bearing deputy the chooses property of pair of machine tool precision influence that wait. Can change original design according to checking a circumstance so, shorten consequently development of new machine tool is periodic.
(5) convenient machine tool checks and accept an experiment to be opposite for machine tool manufactory, appearance of usable ball lever has machine tool routine inspection test quickly, check its precision to whether achieve design requirement. Ball lever appearance already was examined by international machine tool now the standard is recommended like ISO230, ANSI B5.54 use. To factory of machine tool user, appearance of usable ball lever will undertake the machine tool checks and accept an experiment, in order to replace cutting of NAS test specimen, or detect in appearance of the lever that use a ball test specimen is cut again after good machine tool can.
