Embodiment Construction

[0013] The rapid measurement method of flatness and its plane twist is characterized in that: the following steps are followed in sequence:

[0014] (1) Prepare the machine bed to be measured and set the two guide rails on the machine bed as A and B respectively;

[0015] (2) Prepare two contour pads C and D, place the contour pads C and D on the guide rails A and B respectively, so that the contour pad C is located at the front end of the guide rail A, and the contour pad D is located at the back of the guide rail B end; then place the ruler flat on the two contour pads;

[0016] (3), meter frame is set on the lathe bed, dial indicator is installed on the meter frame, the head of said dial indicator is pressed on the middle point of the length and width of the flat ruler, at this moment, obtain the dial indicator Table measured data one;

[0017] (4) Remove the flat ruler from the contour pad, and then exchange the positions of the contour pads C and D, so that the high pad...

Abstract

The invention discloses a rapid metric method of planeness and plane warping thereof, comprising the following steps of setting two guide rails on a body of a machine tool to be measured to a guide rail A and a guide rail B; preparing two a cushion C and a cushion D with equal height, respectively placing the equal-high cushions C and D on the guide rails A and B so that the equal-high cushions C and D are respectively positioned at the front end and the back end of the guide rails A and B; lying a leveling ruler on the two equal-high cushions C and D; providing a gauge frame on the body of the machine tool, mounting a dial gauge on the gauge frame so that a gauge head indicator of the dial gauge is pressed on a neutral point of the length and the width of the leveling ruler to obtain data 1; moving the leveling ruler from the equal-high cushions, exchanging the positions of the equal-high cushions C and D, moving the leveling ruler onto the guide rails A and B from a side , and simultaneously ensuring the neutral point of the length and the width of the leveling ruler to be positioned on a position indicated by the gauge head to obtain data 2 measured by the dial gauge; and subtracting the first data from the second data and multiplying by two to obtain a four-point planeness error which is a plane warping value of a guide rail surface of the machine tool. The method is simple to operate and can easily measure the plane warping value of the guide rail surface of the machine tool.

Description

Technical field: [0001] The invention mainly relates to a measurement method, in particular to a rapid measurement method for flatness and plane twist. Background technique: [0002] The geometric accuracy of the machine tool plays an important role in the quality of the user's product. The overall geometric accuracy of a machine tool is affected by the accuracy of each individual piece that makes up the body. The accuracy of each single piece is correctly detected and guaranteed by several geometric tolerances such as parallelism, straightness, flatness and perpendicularity, so as to ensure the various geometric accuracy requirements of the machine tool. Among them, the flatness requirement is very important. If the moving table moves on the warped surface of the machine tool guide rail, the track of the table will inevitably be warped, and the surface of the processed workpiece will also be warped, which will seriously affect the quality of the product.
