Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a tooling for facilitating replacement of boring rows of a large gantry milling machine. Background Art

[0002] Large gantry milling machines are very important for machining work, and connecting rods are the main parts of diesel engines. Due to the large size of the current models, some large connecting rods need to be machined on large gantry milling machines. During the machining of connecting rods, because boring bars need to be installed and replaced, and the boring bars are heavy, it is very difficult to replace them, so the boring rack plays a very significant role. However, there is currently no reliable, light, and fast boring rack. The boring rack used by Xigen Long Milling is composed of several pads. Not only does it have no buffer during the installation process, but it also increases the risk of tipping. Therefore, according to the characteristics of the boring bars used for boring connecting rods, a boring rack dedicated to Long Milling connecting rods is designed. Utility Model Content

The support leg 16 can be extended and retracted along the inner cavity of the support tube 15, so that the length of the support leg 16 can be adjusted so that the support leg 16 can be close to the ground.

[0033] A support frame 17 is installed at the bottom end of the support leg 16, and a second mounting block 18 is provided in the inner cavity of the support frame 17.

[0037] This device is first used for the replacement method of the boring bar, which is realized through the mounting frame, and its contents include: fixing the large boring bar on the above boring bar placement plate 8, installing the corresponding mandrel 10 on the main shaft or accessory head of the machine tool, using the CNC program to quickly locate the center hole of the boring bar, and slowly extending the mandrel 10 into the center hole of the boring bar, and pausing the CNC program; the operator tightens the connecting bolts after confirmation, fixes the large boring bar on the end face of the main shaft or the end face of the accessory head, rotates the operating panel of the mounting frame, and loosens the top column assembly; continues to run the CNC program, lifts and clears the mounting frame, ends the CNC program, and after confirmation, installs the boring tool on the large boring bar for processing.

[0038] The installation method of the CNC program is as follows: the machine operator starts running the CNC program to stop the spindle accurately and ensure that the spindle stops in the horizontal direction. Run the program again and move to the center mechanical coordinate of the boring bar.
