Abstract

The invention discloses a driving device for an electric spindle of a numerical control machine tool. The driving device is mainly composed of the spindle, bearings, a spindle box body, a shell-free spindle motor, a power source connector, a motor feedback device, a spindle electrical driving module and a cooling device. The spindle is arranged in the shell-free spindle motor, the spindle box body is arranged on the outer side of the shell-free spindle motor, and the bearings are arranged in the positions, on the left side and the right side of the shell-free spindle motor, of the spindle; the lower side of the spindle box body is connected with the cooling device, and the power source connector is formed in the left side of the spindle box body and connected to the upper-left side of the shell-free spindle motor; the motor feedback device is arranged in the position, above the spindle, on the left side of the spindle box body; and the spindle electrical driving module is arranged on the upper-left portion of the power supply connector, the power source connector is connected below the right side of the spindle electrical driving module, and the motor feedback device is connected below the right side of the spindle electrical driving module. The structure is simple, operation is stable, vibrating noise is low, rotational inertia is small, and the production quality and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of spindle drive, and in particular relates to a spindle drive device for a numerically controlled machine tool. Background technique [0002] There are usually three ways to drive the spindle of traditional CNC machine tools: the way that the motor drives the spindle through finite gear transmission, the way that the motor drives the spindle through synchronous belt transmission, and the way that the motor directly drives the spindle. They are suitable for occasions with large, medium and small torque respectively. If these transmission methods are used in high-speed occasions, there will be belt slippage, increased vibration and noise, and large moment of inertia, which will affect the surface processing quality of parts. Contents of the invention [0003] The purpose of the present invention is to provide a CNC machine tool spindle driving device, which has solved the shortcomings in the above solution...
