1. Reciprocating motion of machine tool
The working table of the gantry bed, the ram of the ox head planer or the lap bed, the power machine's power cleaning platform, the broaching tool bar, etc. all use hydraulic transmission to achieve high-speed reciprocating motion. Compared with mechanical transmission. The use of hydraulic transmission can greatly reduce the commutation impact. It can reduce energy consumption and shorten the commutation time. It is conducive to improving productivity and processing quality.
2. Rotary motion of machine tool
The lathe and sharp bed spindle adopt hydraulic transmission to realize the rotary motion. The spindle can be steplessly variable. However, it is inevitable that the hydraulic drive is overturned. In addition, the compressibility of the liquid makes the hydraulic drive unable to guarantee a strict transmission ratio; therefore, the screw drive chain of the lathe and the development drive chain of the gear machine tool are also internally connected. Movement. Hydraulic transmission cannot be used yet.
3. Machine tool feed motion
Hydraulic transmission is more commonly used in the machine tool feed sports equipment. For example, the transmission equipment for the fast-forward and fast-reverse movement of the grinding machine grinding wheel; the tool holder or turret tool holder of the hexagonal lathe, automatic lathe; foot bed, drilling machine, milling machine 2. Working table of planer: The power slide of combined machine tool and so on are widely used hydraulic transmission.
4. Machine tool contouring movement
Apply hydraulic servo system for profiling on lathes, milling machines, and wound beds to realize the automation of complex surface processing. With the development of electro-hydraulic servo valves and electronic technology, various digital program-controlled machine tools and machining centers have become popular. It has improved the level of machine tool automation and processing accuracy. It has created conditions for computer-assisted manufacturing.
5. Sail bed assisted movement
The clamping device on the machine tool, the variable-speed operation and L-screw spider-matrix drying elimination mechanism. The indexing device. The loading and unloading of the workpiece and the knife, the colorful delivery, and the storage equipment all use hydraulic technology. This not only simplifies the structure of the machine tool, but also improves the degree of automation of the machine tool.
