Main transmission system is to achieve the main movement system, its speed is high, the transmission power is big, is one of the key components of the nc machine tools.
Three-dimensional numerical control carving and milling machine tool rotation speed is high, does not fit the traditional & other;
Main motor + belt drive, gear & throughout;
Mode of transmission, and thus using the milling spindle.
Motorized spindle for the high speed nc machine tools and the development of a new type of spindle component, at present has been widely used in high speed cutting machine tools.
Its compact structure, light weight, small inertia, can improve the response characteristics of start, stop, and to control the vibration and noise.
2. Cooling and lubrication of the motorized spindle
work high speed motorized spindle, as soon as possible in order to speed motorized spindle heat dissipation, usually on the walls of the motorized spindle with circulation cooling agent. The machine tool spindle adopts water cooling, the cooling device configuration in the rear of machine tool.
the motorized spindle lubrication way are grease lubrication and oil and gas in two ways, the user can choose according to need. When using grease lubrication, generally the speed of its corresponding relatively lower lubricating oil and gas. Due to the maximum speed of this machine tool spindle requirements are relatively low, The maximum speed of 18000 r/min) , the grease lubrication is adopted.
2. The installation of motorized spindle
the installation of motorized spindle on the machine tool is shown in figure 1. Spindle bearings fixed on the Z axis nc worktable, cylindrical motorized spindle and the bearing in the hole with positioning, motorized spindle lock on bearing by manual spring locking clamping mechanism. Tighten nut bolt 1 move up, drive gland 7 move up, clamping force by bolts and 1 into 90 b arrangement of two transition briquetting 5 evenly spread to pressure ring 6, by means of the transition and briquetting pressure ring 6 45 b layout of 4 press block 2, transfer clamping force evenly to spring up on the set of 4, spring up set of outer wall outward deformation, and the top of the bearing body tight, wall inward contraction, hold close to the main shaft. The clamping mechanism of clamping rigidity is good, good to neutral, simple manipulation, reliable clamping. Figure 1
