At this time, the tool changing arm 44 rotates, and the cylinder 2 42 drives the tool changing arm 44 to rise and fall to achieve picking, and then change the tool.

[0036] Embodiment 2

[0037] Based on Example 1, please refer to Figure 6-7 As shown;

[0038] A three-station tooling plate is made using the existing machine tool, on which a three-jaw chuck is installed and fixed to the machine tool. A three-jaw chuck + positioning pin method is used to achieve a similar Ilowa zero-point quick change effect, eliminating the time for clamping the pressure plate and center correction. The coordinates of the workpieces installed at the three stations are G54 / G55 / G56 from left to right. The X\Y values ​​of G54\G55\G56 are fixed values ​​and can be directly entered manually into the workpiece coordinate system. The Z value is set with tool No. 1 as the reference tool, and the tool compensation of tool No. 1 is set to zero, and the Z value is entered respectively; the tool length compensation values ​​of other tools in the tool magazine (the difference with the No. 1 reference tool) are written into the corresponding tool numbers respectively. When replacing other workpieces, only the No. 1 reference tool needs to be used to align the Z value, and other tools do not need to be set again if the tool length does not change.

[0039] When using the CAM module of ZW3D to make a new program for a single-station mold, it is necessary to add the machine tool three-axis return to zero code (G91 G28 Z0 / G91 G28Y0 / G91 G28 X0) before processing and at each tool change position during post-processing to prevent the tool from colliding with the workpiece during tool change. Then, by combining the programs, the three molds can be processed continuously in sequence. When combining, first put the three folders that need to be combined into the corresponding machine tool folders, and temporarily name the three programs G54\G55\G56 according to the order of the station placement, and replace the coordinate system in the second and third station programs with G55\G56 accordingly, then open the G54 program, drag the cursor to the end of the program, and click to append the file G55\G56. After the combined program is completed, click to find M30 and % and delete them (only keep the program head and tail % and the program tail M30). Then save it as the file name corresponding to the machine tool serial number. The operator assembles the program and opens it to add the three coordinates of G54 / G55 / G56 of the three stations to simulate the three-station G code to ensure the safety of the program. After the simulation, it can be put into the machine tool folder corresponding to the server. Because the mold processing program after the three-station combination is very large, it can only be processed online by DNC, and the FTP mode is used to establish the connection between the machine tool and the machining center.

[0040] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
