Abstract

The invention discloses a built-in machine tool spindle drive device. The built-in machine tool spindle drive device comprises a built-in drive spindle component, a drive mechanism and a coupling, the built-in drive spindle component is arranged at the inner side of a ram, the ram is arranged on a slide saddle, the drive mechanism is arranged at one side of the slide saddle, the drive mechanism is connected with the ram, the built-in drive spindle component is connected with a mechanical spindle through the coupling, the ram, mechanical spindle, coupling and built-in drive spindle component form a ram component, and the ram component is capable of vertically sliding in the slide saddle under the drive of the drive mechanism. The built-in machine tool spindle drive device is compact in structure, the built-in drive spindle component replaces a traditional reduction gearbox, a spindle motor and a transmission shaft, and the weight of a ram moving component is reduced through using the built-in drive spindle component to drive the mechanical spindle; possible vibration caused by the reduction gearbox and transmission shaft is eliminated; the processing precision and running precision of the built-in drive spindle component are much lower than those of the electric spindle; the precision and rigidity of the mechanical spindle are reserved.

Description

technical field [0001] The invention relates to a drive device for a spindle of a numerically controlled machine tool, in particular to a built-in drive device for a spindle of a machine tool, which is used to optimize the ram parts of the spindle of a machine tool. Background technique [0002] For gantry machine tools, the main shaft forms are divided into mechanical main shaft and electric main shaft. The mechanical spindle is driven by a spindle motor, and its transmission chain is as follows: the power is generated from the spindle motor and transmitted to the gearbox through a coupling, and then the gearbox passes through a transmission shaft connected to the mechanical spindle for torque transmission, and finally transmitted to on the mechanical spindle. Among them, the mechanical main shaft is located at the front end of the machine tool ram, the main shaft motor and the reduction box are located above the ram, and the transmission shaft is located between the main ...
