A machine tool spindle device

Abstract

The invention discloses a machine tool spindle device. The device comprises a spindle end head, a spindle seat and a spindle body, wherein the spindle seat is arranged at the upper end of the spindlebody; a ventilating hole is formed in the outer side of the spindle seat; the spindle end head is arranged at the upper end of the spindle seat; a bolt fixing hole is formed in the surface of the upper end of the spindle end head; a fixing ring is arranged at the lower end of the surface of the spindle body; an output shaft is arranged at the lower end of the spindle body; a spindle is arranged inthe spindle body; a spindle motor is arranged at the outer side of the top part of the spindle; a laser positioning device is arranged in an inner gear shaft and is used for realizing laser positioning function; a temperature sensor is arranged and is used for sensing temperature of the machine tool spindle; a clamp A, a clamp B, a clamp C and a clamp D are arranged and are used for clamp equipment such as different cutters; a clamp A spring, a clamp B spring, a clamp C spring and a clamp D spring are arranged and are used for damping the clamps, and thus the damage to the machine tool spindle is reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a machine tool spindle device. Background technique [0002] The machine tool spindle refers to the axis on the machine tool that drives the workpiece or tool to rotate. The main shaft part is usually composed of the main shaft, bearings and transmission parts (gears or pulleys). In the machine, it is mainly used to support transmission parts such as gears and pulleys, to transmit motion and torque, such as machine tool spindles; some are used to clamp workpieces, such as mandrels. Except for machine tools whose main motion is linear motion, such as planers and broaching machines, most machine tools have spindle components. The motion accuracy and structural rigidity of the spindle components are important factors that determine the processing quality and cutting efficiency. The spindle is one of the main components of the machining center, because it...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a machine tool spindle device to solve the problems that the current machine tool spindles proposed in the above background technology often have some defects in use, especially the common machine tool spindles are The integrated structure, so that once the machine tool spindle is damaged, all parts need to be replaced, which not only makes it impossible to use the machine tool to work, but also makes it inconvenient for people to maintain the machine tool spindle, and there are often problems with ordinary machine tool spindles during operation. Some noises have brought some interference to the staff when they are operating. In addition, when installing tools and other equipment, the rotation of the tool also causes a certain amount of pressure on the machine tool spindle, which increases the wear of the machine tool spindle. Accurate and timely positioning cannot be performed during precision operation, so it brings great inconvenience to people.
