The length measuring instrument 2 has a detection head for contact with the slider for detecting the flatness of the slider.
The length measuring instrument 2 can adopt a common dial indicator or a dial indicator to obtain higher measuring precision. Taking a dial indicator as an example, the dial indicator is a gauge type universal length measuring tool manufactured by a precise rack and pinion mechanism. It is usually composed of measuring head, measuring rod, shockproof spring, rack, gear, hairspring, dial and pointer. The working principle of the dial indicator is that a measuring rod caused by the measured size moves in a tiny straight line, and the measuring rod is amplified through gear transmission and changed into rotation of a pointer on a dial, so that the measured size is read. The dial indicator is a measuring instrument which changes the linear displacement of a measuring rod into the angular displacement of a pointer by utilizing the transmission of a rack gear or a lever gear. The dial indicator has a simple structure, the transmission mechanism is a gear train, the external dimension is small, the weight is light, the inertia of the transmission mechanism is small, the transmission ratio is large, the circumference graduation can be adopted, and the dial indicator has a large measurement range, so that the dial indicator can be used for comparison measurement and absolute measurement.
When the flatness of the sliding block towards the working table surface is detected, the side face of the sliding block belt is cleaned, and then the sliding block is moved up and down for 2-5 times and stopped at a position 10-50 mm away from the lower limit. The sliding block is arranged on the upper part and the working table surface is arranged on the lower part. The detection device is vertically placed, the first end A is attached to the workbench surface, the detection head of the length measuring instrument 2, namely the lateral head of the dial indicator, is abutted with the sliding block and pressed into the meter for a certain distance, and the dial indicator generates a reading D 1 The present detection device is moved horizontally along the table surface (through the first endA is bonded with the working table surface) to obtain readings D at different positions 2 、D 3 、D 4 ……D n . The working table surface can be regarded as a horizontal reference surface, and when the side surface of the sliding block facing the working table surface is the theoretical level, the distances between each part and the working table surface are the same, namely D 1 ＝D 2 ＝D 3 ＝D 4 ＝……＝D n . When in actual measurement, all readings are not identical, the difference value among all data reflects the protruding and sinking conditions of the sliding block at all positions of the side face of the working table surface, and a worker can adjust the sliding block according to the data, so that the flatness meets the processing requirement.
