For the position precision pitch compensation of a high-position shaft of a machine tool, the difficult problems of the operability of the position precision and the numerical accuracy of the detection of the shaft are always solved. For example, a heavy gantry machine tool is mainly applied to processing large workpieces, the height of a gantry beam is often more than 3 meters, and a fixed-beam gantry machine tool cannot move due to the beam. The Y-axis fixed on the beam moves horizontally at a position with higher ground clearance, and the linear precision of the Y-axis is directly related to the machining precision of the Y-direction of the machine tool, so that the laser compensation of the position precision error of the Y-axis is particularly important in the machine tool debugging stage. Today, the motion accuracy of the high-order axis cannot be measured directly and accurately by using the existing laser interferometer equipment only to measure the low-order horizontal axis or indirectly by measuring an extension arm driven by the high-order motion axis.
Therefore, a special tool for the laser interferometer is urgently needed to be manufactured, so that a laser head of the special tool can vertically emit laser beams, a complete light path is formed through refraction of an interference mirror and a reflecting mirror, and precision compensation of a high-position axis is directly achieved.
The legend of fig. 1 is: the device comprises a 1-adapter block, a 2-cradle head, a 3-tripod, a 4-first threaded hole and a 5-second threaded hole. As shown in fig. 1, a vertical measurement tool device for a laser interferometer provided by an embodiment of the present utility model includes: the device comprises a conversion block 1, a cradle head 2 and a tripod 3; one surface of the adapter block 1 is provided with a first threaded hole 4 connected with a screw at the top of the tripod 3, and the other surface of the adapter block 1 is provided with a second threaded hole 5 connected with the tripod head 2; the top of the tripod 3 is provided with a screw, and the tripod 3 is connected with the first threaded hole 4 of the adapter block 1 through the screw at the top; the tail of the cradle head 2 is provided with threads, and the cradle head 2 is connected with the second threaded hole 5 of the adapter block 1 through the threads at the tail.
The first threaded hole is formed in the center of one face of the adapter block.
The second threaded hole is formed in the center of the other surface of the adapter block.
Wherein the shape of the adapter block is square.
The adapter block is provided with a threaded connection hole and a trapezoid groove, and the tail of the cradle head is provided with threads for being matched with the adapter block to connect.
Wherein the manufacturing material of the device is stainless steel.
The laser head of the XL-80 laser interferometer is vertically clamped on the holder, so that light beams can be emitted in a vertical plane, an interference mirror is placed at a fixed position of an intersection point of the laser light beams and the axis of the high-order movement axis for refraction, a reflecting mirror is placed on the movement axis, then a complete light path is formed by slightly adjusting the positions of the interference mirror and the reflecting mirror, and the high-order movement axis can be measured and error compensation can be performed after laser collimation.
Because the use condition of the laser head of the original laser interferometer is that the laser head is horizontally clamped on the tripod, laser can only be emitted on the horizontal plane, and the laser head is limited by the heights of the tripod and an operator, when the position accuracy of a high-position shaft is measured, the position accuracy of the movement of a vertical extension arm connected by the high-position shaft is often measured. According to the measuring method, the measuring beam greatly deviates from the axis position of the shaft to be measured, abbe errors are increased, the comprehensive errors of the installation of the extension arm (Z axis of the machine tool) are introduced, and the inaccuracy of high-position Y axis precision detection is increased. The precision of the high-order shaft compensation and the stability of the tool frame used in the tripod are considered, so that software modeling is used, the condition that a laser head is mounted on the tool is analyzed, the tool is designed and manufactured, the tool is used on a production site, and the effect is quite obvious.
