3 Measurement principle
Rolling shaft measuring instrument general technology rolling bearing measuring instrument terminology
Ball bearing R902 groove curvature measurement only technical conditions this device uses radius ratio control device measurement principle to measure bearing sleeve structure, is the measurement of the actual wheel and the ideal measurement process. The principle of the measurement is to induce the probe to rotate synchronously with the main shaft center line, as shown in Figure 1. The stepper motor is driven by the synchronous toothed belt, and the sensor is in the main and auxiliary, starting the motion. When measuring, the sensor probe scans the workpiece groove and obtains the actual groove efficiency relative to the ideal one, which is then sent to the computer for processing through the telecommunications network. The original film shows the groove diameter and groove shape, and the scientific value of the groove shape can be printed.

S.1 The verification method is in accordance with JB/T 5.3.11 Sensor measurement method The sensor is fixed on the micro-motion stand with the probe in a vertical state (or the probe is fixed on the instrument in a self-produced state). The dynamometer is applied with force to the test fire. When the display shows that the lifting part is small\C, the force value is the sensor's measurement method. The measurement coefficient is 4.2.5.3.2. The allowable drop rate of the linear error and the magnification of the sensor are set at 1.57-7. The sensor can be connected to the measuring system. The instrument is pre-set at 31miml: the displacement of C.3m is displayed on the micro-motion stand. The following examples should be correct and meet the requirements of 1.2: Use the micro-frame to give a position of 100~93.5um according to the situation. Record the corresponding display value. Calculate its linear magnification rate. It should meet 4.2. 5.3.3 General determination
》General determination In the micro-frame, the sensor is connected to the system. After the receiver is preheated for 3min, record the displayed value every 30min. The change of the value within 4h should meet 1.2.k) For the system without sensor, record the value displayed on the display every 30min after the instrument is preheated for 30min. The change of the value within 4h should meet 4.2,

R) Select 5.5~5mm size segment G5 grade, send the meter to the calibration room and the scale to the international museum, and require that the error of the inch is within 2 and the error is not greater than 13. ) Connect the standard ball to the calibration table and the instrument on the steel pad, and use the return of the segment as the spindle diameter, which should meet .3.
5.4.2 Lifting angle
Control the angle to the maximum, and read the spindle running angle directly from the scale plate left on the instrument when the spindle stops working without changing the workbench, which should meet 4.3.

Record the time in the angle of the V-block and calculate the shaft speed: 5.5 Move the V-block after working
and use a caliper to directly measure the moving distance of the V-block. It should meet the requirement of 4.1. Use the hand wheel to move the workbench up and down. Use a dial indicator to measure the diameter of the lead square. It should meet the requirements of 4.4.5.6i.6.1 The verticality of the reference surface to the B surface. Use a 0-level 1 cmm square ruler to check whether the degree of flatness is photosensitive and meets the requirements of 4.5, 5.6i.2 The relative straightness of the reference surface. Use the A surface (see Figure 2) to position the inspection station. The straightness of the C surface relative to the A surface should meet the requirements of 4.5, 5.6.3 The flatness of the reference surface. Use a 1-level 0.5 mm flat mirror to check the flatness of the reference. The line should not be less than 1/2 ten. When conducting a comprehensive inspection, it can be combined with the equal-volume decision as the standard. 5.7 Total Accuracy
On the actuator, measure the standard steel ball, and according to the following formula, calculate the vertical position of the scale card with a standard gauge block or a standard steel or metal gauge. The calibration method is as follows:
) Install the calibration table with a standard ball on the workbench, and make the center of the steel ball coincide with the center of the main object (the workbench). The number shown on the indicator is "steel track". When the gauge block is combined with the reference block, the number of the gauge block is The standard ball diameter is less than the standard ruler. The design should be appropriate. Remove the calibration table and put the standard decision. Turn off the power of the stepper motor and turn the electric pen to find the number printed on the F-point on the book "accurate fast hair". 5.8 Only the group accuracy is s.8.1 The reading of the value is 5.-s.5m. The diameter of the ball is not adjusted before the ball is adjusted to the surface of the country), and the actual verification result is compared with the measurement result. 5.8.2 The indication of the property is to ensure that the measurement tea meter remains unchanged, for the time: abandon the feeling, cut the surface calcium 1 time, record the radius of the groove, and the value change is 4. 7. 6 Inspection rules 6.1 According to the current technical requirements and JB door 5307 signed inspection requirements, the city manufacturing department shall prepare. 6.2. Before a fake device is released! It must be inspected and qualified by the quality inspection department and accompanied by a certificate of conformity before it can be shipped out of the factory. 7. Marking, packaging, transportation and storage
