As the machining center is a large and medium-sized CNC machine tool, the machine tool factory needs to disassemble the machine tool into several parts when it is delivered. After the machine tool is in place, it needs to be re connected and installed. Therefore, after the machine tool is in place, it is necessary to repeatedly adjust the level of the main bed of the machine tool by adjusting the foot bolts and pad iron used in the fixed foundation of the machine tool, so that the parallelism of each axis in the full stroke is within the allowable range. And in order to ensure the stability and reliability of the machine tool in the power cutting, it is also necessary to pay attention to make all the pad iron in the pad state. Considering that the cement foundation is not stable enough, it is generally required to fine adjust the machine tool level after several months to half a year, so as to ensure the accuracy stability of the machine tool in K period.
The main parts of the machining center need to be adjusted, such as the relative position of manipulator, spindle and tool magazine, as well as the relative position of pallet and exchange table, so as to ensure the accuracy, stability and reliability of tool change and worktable exchange. The adjustment methods and requirements are as follows.
(1) Adjust the relative position of manipulator, spindle and tool magazine. Use gz8yozo or c30yozo program to make the machine automatically run to the tool change position, and then use it to change the tool step by step in the dynamic mode, and check whether the actions of grasping, loading and drawing are accurate and appropriate. If there is any error, you can adjust the stroke of the manipulator or move the position of the manipulator support or tool magazine. If necessary, you can also change the setting / (parameter setting /) of the coordinate value of the tool change base. After adjustment, tighten the adjusting screws, and then change the tool several times. It is better to use several toolholders which are close to the maximum allowable weight for repeated tool changing experiments, so as to achieve accurate action, no impact and no knife drop.
(2) Adjust the change of supporting plate spoon: I is the relative position of the table. For double or multiple worktables, the relative position of the pallet and the exchange worktable must be carefully adjusted to ensure the stability and reliability of the automatic exchange of the worktable. During the adjustment, the worktable should be equipped with more than 50% of the rated load for the automatic exchange operation of the worktable.
