Problems solved by technology

[0004] 1. The taper hole of the high-speed electric spindle of the CNC machine tool in the prior art is easy to wear because the tool is often inserted and pulled out. After the wear, the maintenance of the spindle is complicated, the workload is large, and the requirements for personnel skills are high; the bearings replaced during maintenance are new. Matching, the main shaft needs to be run-in and pre-run separately, which takes a long time
[0005] 2. There are no monitoring measures for the state of the spindle itself;
[0006] 3. There is no reliable quantitative data on the position of the machining tool installed in the spindle;
[0007] 4. The spindle and its own performance parameters cannot be extracted during use;

Embodiment 1

[0034] As the most basic implementation of the present invention, a high-speed electric spindle structure with intelligent monitoring and quick maintenance is disclosed, such as figure 1 with 2 , Including an outer shell and a spindle body set in the shell; the shell includes a front bearing seat 1, a rear bearing seat 2 and a middle shell sleeve 3, and the shell is provided with sound waves for monitoring the spindle body Sensor 4, acceleration sensor 5, temperature sensor 6, cone detection ring 12 and analog sensor 7;

[0035] The main shaft body includes a precision taper sleeve 14 and a main shaft rod 8. The front and rear ends of the main shaft rod 8 are both sleeved with transition bearings 9 and the middle shell sleeve 3 of the housing is provided with a rotating shaft for driving the main shaft rod 8. The driving device 10; the spindle rod 8 is inserted in the middle of the housing through the transition bearings 9 at both ends, and the transition bearings 9 at both ends c...

Embodiment 2

[0038] As a preferred embodiment of the present invention, a high-speed electric spindle structure with intelligent monitoring and quick maintenance is disclosed, such as figure 1 , 2 And 3, including an outer shell and a main shaft body set in the shell; the shell includes a front bearing seat 1, a rear bearing seat 2 and a middle shell sleeve 3, and the shell is provided with a monitor for the main shaft body Acoustic wave sensor 4, acceleration sensor 5, temperature sensor 6, cone detection ring 12 and analog sensor 7;

[0039] The main shaft body includes a precision taper sleeve 14 and a main shaft rod 8. The front and rear ends of the main shaft rod 8 are both sleeved with transition bearings 9 and the middle shell sleeve 3 of the housing is provided with a rotating shaft for driving the main shaft rod 8. The driving device 10; the spindle rod 8 is inserted in the middle of the housing through the transition bearings 9 at both ends, and the transition bearings 9 at both ends...

Embodiment 3

[0044] This embodiment provides a new type of high-speed electric spindle structure applied to the intelligent monitoring and quick assembly and disassembly adjustment of CNC machine tools. Such as figure 2 , The main shaft body parts are split into precision taper sleeve 14 and spindle rod 8 two precisely connected and installed parts. When the taper hole of the precision taper sleeve 14 part is damaged, only the precision taper sleeve 14 part needs to be removed for replacement and installation , The operation is simple; after the main shaft body is damaged, only the 14 parts of the front precision taper sleeve are replaced, the cost is greatly reduced, and the operating system itself has been verified for a long time. After the taper sleeve is replaced, the original high-speed and operating accuracy performance can be maintained.

[0045] This technical solution integrates intelligent monitoring, discrimination and control with advanced high-speed motorized spindle technology,...

Abstract

The invention discloses a high-speed electric spindle structure with intelligent monitoring and quick maintenance functions and belongs to the technical field of machine tool high-speed spindles. Thehigh-speed electric spindle structure with the intelligent monitoring and quick maintenance functions comprises a shell on the outer portion and a spindle body arranged in the shell. The shell comprises a front bearing pedestal, a rear bearing pedestal and a middle casing, and is provided with a sound wave sensor, an acceleration sensor, a temperature sensor, a conical surface detection ring and an analog quantity sensor which are used for monitoring the spindle body. The brand new intelligent high-speed electric spindle has the intelligent distinguishing function and is applied to a numericalcontrol machine tool and can achieve quick replacement structurally, the states, such as cutting vibration, noise and temperature, of the spindle are intelligently distinguished in real time in the processing and application process of the high-speed electric spindle, meanwhile, the position of an intelligent control cutter-changing cutter assembled in the spindle is accurately distinguished, andthe spindle state is distinguished and optimized through an intelligent control system of the machine tool.

Description
