Abstract
The utility model discloses a high-speed electric main shaft with a screw thread locking device, which comprises a main shaft, a stator, a rotor, a bearing and a sealing cover. The screw thread locking device is arranged at the front end (1) of the main shaft and is formed in the following mode. Two holes with opposite position direction are arranged on the sealed cover (3) which is locked with the main shaft by the screw threads by screws (2). After the structure is adopted, the utility model can effectively prevent the sealing cover from back loosening to result in a state that the high-speed main shaft is incapable of operating, so the operating stability of the high-speed main shaft is improved.
Description
Technical field
The utility model relates to a kind of electric spindle technology, especially relates to a kind of high-speed electric main shaft technology of threaded locking device.
Background technology
The electricity main axle unit is the very high electromechanical integrated product of a kind of technology content, through development and perfect constantly, its application spreads all over the enterprise of machine industry, bearing industry, electronics processing industry, Mould Machining industry, instrument processing industry and rotation of all needs high speed and High-speed machining.In process, when high-speed electric main shaft is shut down, the state that can cause high-speed electric main shaft to work usually owing to the Hui Song of seal cover.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of when high-speed electric main shaft is shut down, and can effectively prevent the technology of seal cover Hui Song.
Technical problem to be solved in the utility model is achieved by the following technical solution: it comprises main shaft, stator, rotor, bearing, seal cover, and the place is provided with screw-threaded coupling device at front-end of spindle.Described screw-threaded coupling device is to constitute like this, has two positions hole in opposite directions on seal cover, and screw makes seal cover and principal shaft locking by screw thread.
The said structure that the utility model adopts can effectively be stopped when high-speed electric main shaft is shut down, the state that seal cover Hui Song causes high-speed electric main shaft to work, thus improved the job stability of high-speed electric main shaft.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Figure 1 shows that the structural representation of the high-speed electric main shaft of threaded locking device
The specific embodiment
As shown in Figure 1, screw-threaded coupling device is made of seal cover 3, screw 2.Have two positions hole in opposite directions on seal cover 3, screw 2 makes seal cover 3 and principal shaft locking by screw thread.When electric main shaft runs up the back shutdown, because screw 2 makes seal cover 3 and principal shaft locking by screw thread, stopped seal cover and returned the generation of loose phenomenon, thus the state of having avoided high-speed electric main shaft to work.In the utility model, no matter how the Kong Weizuo on the seal cover is changed, to the increase of the number in hole and to the conversion of screw fastener, all should be considered as having fallen into protection domain of the present utility model.
Claims (2)
1, a kind of high-speed electric main shaft of threaded locking device comprises main shaft, stator, rotor, bearing, seal cover, it is characterized in that locating to be provided with screw-threaded coupling device at front-end of spindle (1).
2, the high-speed electric main shaft of threaded locking device according to claim 1 is characterized in that screw-threaded coupling device is to constitute like this, has two positions hole in opposite directions on seal cover (3), and screw (2) makes seal cover (3) and principal shaft locking by screw thread.
