[0002] The ram of vertical turning and milling machine tool needs to realize two functions, namely turning function and milling function, the tool needs to be stationary when using the turning function, and the tool needs to rotate when using the milling function. When changing the tool, the tool needs to be knocked down from the ram in the machine tool with a tool magazine, the tool magazine will be deformed if the tool knocking distance is long, and the tool cannot be knocked down if the tool knocking distance is short, so the tool knocking distance needs to be accurately adjusted.

[0003] The general tool changing process is as follows: the tool breaking cylinder pushes the drawbar forward; the drawbar pushes the drawbar claw forward through the transmission of the related connecting piece, and the drawbar claw moves forward while opening the drawbar claw; the front end of the drawbar claw is tightly attached to the draw pin, and then a small stroke (i.e. the tool lifting amount, such as 0.5mm) is continuously pushed forward to separate the tool handle taper surface from the spindle taper surface, and finally the tool changing is completed with the assistance of the mechanical arm. However, the tool breaking bolt position of the existing spindle tool breaking cylinder is generally a certain value and cannot be adjusted, or the thickness of the adjusting pad is changed for adjustment. In the tool changing process, due to the existence of dimensional tolerance, the final tool lifting amount cannot be controlled after error accumulation, and the tool lifting amount needs to be adjusted through many links such as disassembly, assembly, size matching and grinding, which consumes time and assembly time.

[0029] Referring to Figure 1 The tight screw 4 is threadedly connected to the right side of the top of the oil cylinder body 3 and penetrates the oil cylinder body 3, and the end of the tight screw 4 is arranged on the outer side of the adjusting screw 8. The tight screw 4 penetrates the oil cylinder body 3 and abuts against the outer portion of the adjusting screw 8, so as to limit the adjusting screw 8. The installation groove 6 is formed in the outer ring of the piston 5, the O-shaped ring 7 is fixedly connected in the installation groove 6, and the sealing property of the piston 5 can be improved through the O-shaped ring 7. The pull rod 2 penetrates the adjusting screw 8, and the outer portion of the pull rod 2 is slidably connected to the inner wall of the adjusting screw 8. The pull rod 2 is thin in the upper portion and thick in the lower portion, so that the distance between the adjusting screw 8 and the thick pull rod 2 can be adjusted, and the tool breaking stroke is adjusted. The outer portion of the adjusting screw 8 is slidably connected to the inner portion of the piston 5, and the lower portion of the piston 5 is fixedly connected to the outer portion of the thick pull rod 2.
