The implementation principle of the machine tool station fixing method disclosed by the embodiment of the application is as follows: the distribution structures of the positioning and pressing cylinders 21 on the detection table 5 and the processing equipment workbench are kept the same, so that the workpiece on the mobile table 1 keeps the same processing zero point and mounting precision on different subsequent processing equipment workbench, and the processing continuity, the processing efficiency and the transposition efficiency are improved. One of the positioning pressing cylinders 21 in the pushing direction pushes the movable table 1 and releases the pushing action, the other positioning pressing cylinder 21 in the pushing direction pushes the movable table 1 and positions the movable table 1, and the movable table 1 can be positioned by driving all the positioning pressing cylinders 21 to push the movable table 1 without contracting the piston rod again, so that the movement of the movable table 1 is favorably reduced due to mutual interference of the positioning pressing cylinders 21 in each pushing direction;
the two mobile stations 1 facilitate an operator to clamp a workpiece by using the other mobile station 1 and correct the workpiece processing zero point and the installation precision in the workpiece processing process carried by the previous mobile station 1, so that the workpiece clamping and processing efficiency is improved.
The embodiments of the present application are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in this way, therefore: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
