It is a multifunctional mechanical equipment composed of a column and a mechanical slide that can mill end faces, sides, bore holes, and drill holes. It mainly grinds the workpiece surface flat by high-speed rotation of the milling cutter.
[0003] In the process of machining a workpiece using an end mill, the workpiece being machined is fixed and restricted by the workpiece positioning device of the end milling machine, and then the position of the milling cutter is adjusted according to the machining position of the workpiece being machined as needed. When adjusting the position of the milling cutter, it is necessary to put shaft sleeves of different thicknesses on the outside of the rotating shaft, and then place the milling cutter on the shaft sleeve at an appropriate position height and fix the shaft sleeve. However, the thickness of the shaft sleeve is relatively fixed. When making slight adjustments to the position of the milling cutter, it is inconvenient for the user to adjust the milling cutter, and the operation of replacing shaft sleeves of different thicknesses to adjust the position of the milling cutter is relatively cumbersome. Therefore, a new tool adjustment mechanism for end milling is proposed to address the above problems. Utility Model Content

At this time, the position of the milling blade can be adjusted as needed, and then after determining the position of the milling blade, the second nut is rotated again to move the second nut to a position close to the milling blade, so that the reducing ring squeezes the elastic sheet, and then the anti-sliding block is tightly attached to the rotating shaft again. At this time, the position of the milling blade can be adjusted and fixed. This device mechanism greatly facilitates the user to adjust the position of the milling blade, and avoids the tedious operation of replacing shaft sleeves of different thicknesses to adjust the position of the milling blade.

[0022] The number of elastic sheets 9 is the same as the number of anti-sliding blocks 8. The elastic sheets 9 are evenly distributed on the outside of the external threaded tube 10. The elastic sheets 9 are tightly attached to the reducing ring 17. The reducing ring 17 slides on the outside of the rotating shaft 7, which is convenient for stably fixing the external threaded tube 10 on the outside of the rotating shaft 7. There are two threaded columns 13, which are symmetrically arranged on the same side of the ring plate 12. The threaded columns 13 are arranged in the holes opened on the inner side of the milling blade 15. The first nut 14 is tightly attached to the milling blade 15, which is convenient for the milling blade 1 5 is stably restricted on the ring plate 12; the maximum inner diameter of the reducing ring 17 is the same as the inner diameter of the second nut 16, and the inner diameter of the reducing ring 17 is reduced from bottom to top, so that the reducing ring 17 increases the thrust acting on the elastic sheet 9 as the second nut 16 is connected to the external threaded barrel 10; the inner and outer diameters of the cylinder 11 are the same as the inner and outer diameters of the external threaded barrel 10, and the cylinder 11 slides on the outer side of the rotating shaft 7, and the inner diameter of the milling cutter 15 is the same as the outer diameter of the cylinder 11, so that the milling cutter 15 can be easily disassembled and installed.
[0023] Working process: During use, the equipment is powered by an external power supply. When it is necessary to adjust the tool position on the face milling machine, the cover 5 on the face milling machine can be opened, and then an appropriate tool is used to control the rotation of the second nut 16 on the outer side of the rotating shaft 7, so that the second nut 16 is spirally rotated on the outer side of the external threaded barrel 10, so that the second nut 16 gradually moves away from the milling cutter 15 and disengages from the outer side of the external threaded barrel 10. At the same time, the reducing ring 17 fixedly connected to the outer side of the second nut 16 releases its squeezing force on the elastic sheet 9 as the second nut 16 moves, so that the elastic sheet 9 can drive the anti-sliding block 8 to which it is fixed to restore to a position away from the center of the rotating shaft 7. At this time, the external threaded barrel 10 is moved, so that the external threaded barrel 10 can drive the milling cutter 15 on the outer side of the cylinder 11 to move linearly through the cylinder 11 to which it is fixed and the ring plate 12 to which it is indirectly fixed, thereby realizing the adjustment of the position of the milling cutter 15 in the face milling machine. After 15 moves to the appropriate position, the second nut 16 can be rotated in the opposite direction, so that the second nut 16 and the external threaded tube 10 are spirally connected together again, and the reducing ring 17 is reconnected with the external threaded tube 10 along with the second nut 16. The reducing ring 17 can squeeze the elastic sheet 9 again, so that the elastic sheet 9 and the anti-sliding block 8 fixedly connected thereto are tightly attached to the outer side of the rotating shaft 7, so as to achieve the fixing of the adjusted position of the milling blade 15 of the end milling machine. The milling blade 15 of the end milling machine is sleeved on the threaded column 13 fixedly connected to the ring plate 12 through the hole opened on its inner side, and is fixedly restricted by the first nut 14 spirally connected to the outer side of the threaded column 13, so as to ensure the stability of the connection between the milling blade 15 and the ring plate 12, and facilitate the user to replace the milling blade 15. This device mechanism greatly facilitates the user to adjust the position of the milling blade 15, and avoids the cumbersome operation of replacing shaft sleeves of different thicknesses to adjust the position of the milling blade 15.
