High-speed engraving and milling electric spindle

Abstract

The invention relates to a high-speed engraving and milling electric spindle. The high-speed engraving and milling electric spindle comprises an engine body with an inner cavity, and a rotating shaft system, an aluminum water jacket, a broach system, an air sealing system, a water cooling system and a driving motor which are arranged inside the engine body, wherein a pull rod is penetrated inside a central spindle, and one end of the pull rod is penetrated inside the aluminum water jacket and opposite to a piston; a pulling claw assembly is arranged at one end, far away from the piston, of the pull rod and used for clamping a knife handle; the air sealing system comprises through grooves formed in the aluminum water jacket, a bearing seat outer sleeve and the engine body; the air sealing system comprises cooling water holes formed in an air cylinder, the aluminum water jacket, the bearing seat outer sleeve and the engine body. Compared with the prior art, the high-speed engraving and milling electric spindle disclosed by the invention is cylindrical, and the outer diameters of the engine body, the bearing seat outer sleeve, the aluminum water jacket and the air cylinder are basically the same. Meanwhile, the total length ratio of the engine body, the bearing seat outer sleeve, the aluminum water jacket and the air cylinder is 1: 1, so that the high-speed engraving and milling electric spindle is more balanced in the aspect of structural arrangement.

Description

[0001] technical field [0002] The invention relates to a high-speed engraving and milling electric spindle. [0003] Background technique [0004] The electric spindle is also called the motor built-in spindle, which is directly driven by the internal motor, instead of requiring an external servo motor to work like the traditional mechanical spindle. The electric spindle has a compact structure, so it can achieve high speed, high precision and high running stability. However, due to the limitation of the volume of the spindle, the built-in motor is generally smaller, and its power and output torque are smaller than those of traditional mechanical spindles. [0005] Contents of the invention [0006] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a high-speed engraving and milling electric spindle with stable operation, high rotation speed and large torque. [0007] To achieve the above object, the present invention adop...
