Description
Technical field
The utility model belongs to detection technique, relates to a kind of test fixture that is used for accelerometer commissioning device on-line calibration.
Background technology
The used horizontal-vertical double-purpose precision indexing equipment of certain type accelerometer debugging, its main debugging working state is a horizontal state.At present, during Equipment Alignment, we need commissioning device is measured the main shaft adjustment, is installed to vertical and can installs and measures standard and calibrate, and calibration finishes and again equipment returned to horizontal duty.Like this, installing/dismounting trouble, time-consuming, non-again production debugging use location, Equipment Alignment position; And for really limiting or the production debugging accuracy requirement because of the workplace, when the device measuring main shaft must be in horizontal state, we need rely on magnet that the measurement standard device is connected with the absorption of commissioning device work top and calibrate.Like this, measurement standard device and commissioning device table top verticality can't be adjusted; Secondly; Because the size of magnet absorption affinity can not be controlled, during the right alignment adjustment of measurement standard device and revolving shaft, rely on operator's feel, range estimation, experience to promote measurement standard device centering; Low, the poor reliability of adjustment efficient; And measurement standard also has the danger of landing in pushing course, very dangerous, testing efficiency is low.
Summary of the invention
The purpose of the utility model is: propose a kind ofly to improve measuring accuracy and testing efficiency, accelerometer commissioning device on-line calibration that reliability is high is used frock.
The technical scheme of the utility model is: a kind of accelerometer commissioning device on-line calibration is used frock; It comprises transition disc, measurement standard device, adjustment ball and adjustment screw and trip bolt; Said transition disc is a circular configuration, and peripheral several band grooves that evenly are provided with are used for the screw thread via hole that trip bolt is installed, and the center is the ball-and-socket that is used to place the adjustment ball; Around ball-and-socket is some equally distributed threaded holes that screw is installed that are used to adjust; Said transition disc links to each other with precision indexing equipment through trip bolt, and before the trip bolt locking, has hole between screw thread via hole and the trip bolt; Said measurement standard device links to each other with transition disc through the adjustment screw, and its lower surface contacts with the adjustment ball that is arranged on ball-and-socket simultaneously.
Said ball-and-socket is of a size of R4mm.
Said screw thread via hole is 8, is uniformly distributed in the transition disc periphery.
The said threaded hole that is used to install the adjustment screw is 4.
The utility model has the advantages that: the utility model accelerometer commissioning device on-line calibration is with design and the adjusting of frock through screw thread via hole on the transition disc; Realized the centering, adjustable of the measurement standard device and the precision indexing machine spindle centre of gyration; Realize that through adjustment screw 5 and adjustment ball the verticality of measurement standard device workplace and commissioning device table top is adjustable simultaneously, so correction accuracy is high, good reliability.Like this, during Equipment Alignment, can be under the vertical and horizontal two states at main shaft and carry out, can carry out online detection to commissioning device easily at test process, therefore can shorten the alignment time, reduce labour intensity, efficiency of measurement improves more than 4 times.
