Problems solved by technology
[0003] After the previous guide rails were installed, in order to ensure the parallelism between the two guide rails, a high-precision tape measure was generally used to directly measure the distance between the two guide rails. Although this measurement method is easy to operate, it cannot meet the requirements due to poor accuracy. Machine tool requirements for high parallelism of two guide rails
In order to improve the measurement accuracy of measuring parallelism, there is currently a machine tool guide rail tester that can achieve high-precision measurement of guide rail parallelism, but because this machine tool guide rail tester is relatively large, it is inconvenient to transport and install. A long-span machine tool guide rail that needs to be installed at the customer's site, the measurement of parallelism is extremely inconvenient and costly

The invention provides a large-span machine tool guide rail parallelism measuring device, which comprises a left guide rail slider matched with a left guide rail, and a right guide rail slider fixed with a left connecting block and a right connecting block; the right connecting block is fixed with a laser flashlight; the left connecting block is provided with a centering block corresponding to the laser flashlight; the centering block is provided with a laser centering reference point; a high precision steel ruler is connected between the left and right connecting blocks through a steel wire and a tension spring; a value indicating part of the high precision steel ruler falls on the middle part of the right connecting block; and the right connecting block is provided with a reading reference line of the high precision steel ruler. The invention also provides a measurement method according to the large-span machine tool guide rail parallelism measuring device. The invention has the advantages of high measurement accuracy and simple operation and transportation.
Description
technical field [0001] The invention relates to a measuring device, in particular to a parallelism measuring device, in particular to a measuring device and a measuring method for the parallelism of guide rails of a large-span machine tool. Background technique [0002] At present, in the field of machine tool manufacturing, the parallelism of the guide rails on the machine tool is very high, especially in some wood processing machine tools, the span of the guide rails is very large. After the customer purchases the machine tool, the guide rails are generally transported to the Install it after the customer is there. [0003] After the previous guide rails were installed, in order to ensure the parallelism between the two guide rails, a high-precision tape measure was generally used to directly measure the distance between the two guide rails. Although this measurement method is easy to operate, it cannot meet the requirements due to poor accuracy. The machine tool requires...
