Embodiment 1
[0045] see figure 1 , this embodiment takes the bridge-type large-scale gantry machine tool as an example to introduce the installation method of its gantry structure. see figure 2 , the method includes the following steps.
[0046] Step 1: Installation of Workbench 1.
[0047] Install the workbench 1 on the ground, or install it on a corresponding machine base as required. The installation of the workbench 1 is carried out by a conventional installation method, and the flatness and levelness of the workbench 1 need to be ensured during installation.
[0048] As a large-scale gantry machine tool for precision machining, especially a large-scale gantry machine tool in the field of laser processing technology, the workbench 1 chooses a granite workbench that meets the national standard of GB / T20248-2006 rock slabs to ensure that it has a grade 0 stipulated by the national standard Or Class 1 flatness tolerance.
[0049]Adjustment of levelness is carried out by conventional...
Embodiment 2
[0105] Embodiment 2 is similar to the method of embodiment 1, but, when carrying out the fine adjustment of perpendicularity, can adopt such as Figure 4 The fine adjustment device 8 shown performs the adjustment.
[0106] The fine adjustment device 8 includes a pull plate. The pull plate is a pull plate with an L-shaped cross section, one end is a fixing portion 81 , and the other end is an adjusting portion 82 . Fix according to the parts that need to be adjusted. For example, when it is necessary to adjust the verticality of the Y-axis guide rail 5 and the X-axis guide rail 4, the fixing part 81 is fixed on the fixed surface of the Y-axis guide rail 5, or the fixing part 81 is fixed on the Y-axis On the fixed surface of the Y-axis beam 6 where the guide rail 5 is located, the adjusting part 82 is fixed on the Y-axis guide rail 5 to be adjusted or the Y-axis beam 6 .
[0107] The adjustment part 82 includes a push rod 83 and a pull rod 84. The push rod 83 is a threaded rod...
Embodiment 3
[0116] This embodiment takes the fixed beam type and the moving beam type large-scale gantry machine tools as examples to illustrate the installation method, which is similar to the second embodiment.
[0117] The difference is that the installation of the X-axis guide rail 4 is completed first, and the parallelism of the X-axis guide rail 4 is adjusted. Then, the workbench 1 is installed on the slider of the X-axis guide rail 4, and the levelness of the workbench 1 is tested. Adjust the levelness of the workbench 1 by plugging the gasket in the fixed part of the slide block between the table 1 and the X-axis guide rail 4. Then complete the installation of the Y-axis guide rail 5 .
[0118] The difference lies in that when vertically adjusting the Y-axis guide rail 5 and the X-axis guide rail 4, the drawing method is different. Specifically, first move the slider of the Y-axis guide rail 5 to one end of the Y-axis guide rail 5, and the working table 1 Move to one end of the X...
