Disc spring assemblies, motorized spindles and processing equipment

Abstract

The invention provides a disc spring assembly, an electric spindle and processing equipment. The disc spring assembly includes a coaxial first disc spring body and a second disc spring body. The first disc spring body is provided with a first boss. The first boss is a body of revolution formed by a first rectangular surface rotating around the axis. The first boss extends axially away from the first opening. The first disc The spring body is provided with a first central hole penetratingly along the axial direction. The second disc spring body is provided with a second center hole through the axial direction, the first axial end of the second disc spring body is provided with a second boss, and the second boss is a second rectangular surface that rotates around the axis The rotary body is formed around a circle, and the second boss extends axially away from the second central hole. The inner peripheral wall of the second central hole is adjacent to the outer peripheral wall of the first boss of the adjacent first disc spring body. The inner peripheral wall of the second boss is adjacent to the outer peripheral wall of the first axial end of the adjacent first disk spring body. The disc spring assembly can be automatically guided and positioned to improve fit tightness and bearing capacity.

Description

technical field [0001] The invention relates to the technical field of an electric spindle, in particular to a disc spring assembly, an electric spindle and processing equipment. Background technique [0002] The disc spring assembly consists of multiple stacked disc spring bodies. Each disc spring body is in the shape of a flat conical disc. Unlike traditional springs, the disc spring body is a kind of spring washer. The main features are: large load and short stroke , The required space is small, the combination is convenient, the maintenance and replacement are easy, the economy and safety are high, and the service life is long. [0003] At present, there are many types of disc springs, such as ordinary rectangular cross-section disc springs, rectangular cross-section disc springs, trapezoidal cross-section disc springs, slotted disc springs, and diaphragm disc springs, most of which are standardized ordinary rectangular cross-sections. The disc spring body, the cross-se...

Problems solved by technology

[0003] At present, there are many types of disc springs, such as ordinary rectangular cross-section disc springs, rectangular cross-section disc springs, trapezoidal cross-section disc springs, slotted disc springs, and diaphragm disc springs, most of which are standardized ordinary rectangular cross-sections. The disc spring body, the cross-sectional shape and fixing method of the disc spring body directly affect the performance of the disc spring body, and there are still some deficiencies in the prior art: when the disc spring body is stacked and combined, it must have an inner guide or an outer guide and other external guiding devices, this conventional fixing method is difficult to use in some special occasions, and the installation process is extremely cumbersome and difficult
