Electric spindle arranging structure easy to replace motor and using method thereof

Abstract

The invention discloses an electric spindle arranging structure easy to replace a motor, which comprises a mandrel (4), a spindle motor component (1), a clamping disk component (7), a rear-end bearing assembly (2) and a front-end bearing assembly (3), wherein the spindle motor component (1) is fixed on the rear side of the rear-end bearing assembly (2); the spindle motor component (1) comprises a stator (11), a rotor (12) and a rotor bushing (13); an inner ring of the rotor bushing (13) is provided with a concave groove to form an annular gap (32) between the rotor bushing (13) and the mandrel (4); and the rotor bushing (13) is provided with an oil hole (31) communicated with the gap (32). The structure has multiple functions by conveniently replacing the spindle motor component. The working range of single equipment is greatly improved and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of motors, and more specifically relates to a workpiece electric spindle structure for easily replacing motors in a horizontal turning-milling compound machining center. Background technique [0002] Due to the performance of the motor itself and the level of its manufacturing industry, it is difficult for a motor with a certain volume to have both high speed and high torque characteristics at the same time. Due to the different characteristics of the electric spindle, the processing effect it can achieve is also different. According to this idea, the high-efficiency machine tools that are more suitable for high-speed machining and the low-speed machine tools that are more suitable for high-torque machining are divided accordingly. With the development of the manufacturing industry, the technological requirements for workpieces are increasing, and most mechanical parts require high-speed processing and high-torque pr...

AI Technical Summary

Problems solved by technology

The biggest problem with this structure is that it is very inconvenient to achieve the purpose of replacing the motor spindle by disassembling and replacing the spindle motor.

Because, unlike the replacement of the spindle motor assembly, the bearing assembly on both sides needs to be removed. This operation is not only cumbersome, but more importantly, for precision motor equipment, the installation accuracy of the bearing assembly is an important factor affecting the output accuracy of the motor.

However, the above method of disassembling the bearing assembly will often damage the bearing assembly, and then make the whole set of equipment scrapped.
