Problems solved by technology

Since the electric spindle integrates the motor into the spindle unit, and the speed is very high, a large amount of heat will be generated during operation, which will cause the temperature rise of the electric spindle, deteriorate the thermal characteristics and dynamic characteristics of the electric spindle, and affect the normal operation of the electric spindle.

Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described:

[0020] See figure 1 , the present invention relates to a ball high-speed electric spindle 100, which includes a body 10, a bearing housing 20, an aluminum water jacket 30, a shaft core assembly 40, a tool changing system 50 for changing a tool 99, an air cooling system 60 and an air sealing system 70. The body 10 is generally T-shaped, and the middle part thereof is inwardly recessed to form a first receiving cavity 11 . The bearing seat 20 is disposed between the machine body 10 and the aluminum water jacket 30 , and is co-enclosed with one end of the machine body 10 to form a second receiving cavity 21 . The aluminum water jacket 30 is disposed on the bearing seat 20 , and together with the end of the bearing seat 20 away from the machine body 10 , surrounds and forms a third receiving cavity 31 . Wherein, the first storage cavity 11 , the seco...

Abstract

A high-speed ball electric spindle (100) comprises a machine body (10) that is arranged with a first accommodating cavity (11), an aluminum water sleeve (30), a bearing seat (20), a rotor shaft core (41), a motor (42), a tool changing system (50) and an air cooling system (60). The machine body and the bearing seat are arranged in an enclosed manner to form a second accommodating cavity (21), and the bearing seat and the aluminum water sleeve are arranged in the enclosed manner to form a third accommodating cavity (31). The rotor shaft core runs through the first accommodating cavity, the second accommodating cavity and the third accommodating cavity. The air cooling system comprises a fan (61) and a cooling air channel (63), wherein the cooling air channel comprises several air inlets (631), several air outlets (633) and a first vent gutter (632). The fan is located in the third accommodating cavity and is driven by the motor to rotate together with the rotor shaft core.

Description

technical field [0001] The invention relates to a ball high-speed electric spindle, in particular to a ball high-speed electric spindle with an air cooling system. Background technique [0002] The electric spindle is a new technology that integrates the machine tool spindle and the spindle motor in the field of CNC machine tools in recent years. Since the electric spindle integrates the motor into the spindle unit, and the speed is very high, a large amount of heat will be generated during operation, which will cause the temperature rise of the electric spindle, deteriorate the thermal and dynamic characteristics of the electric spindle, and affect the normal operation of the electric spindle. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a ball high-speed electric spindle with an air cooling system. [0004] To achieve the above object, the present invention adopts the following technica...
