Spindle structure

The creation system is related to a spindle structure, in particular, a spindle structure is provided with a body, a spacer ring, a front cover, a rotating shaft, an enclosing member and a liquid-proof cover, and the liquid-proof cover is assembled at an end of the rotating shaft. The outer surface of the liquid-proof cover is provided with a liquid-proof convex ring, the liquid-proof convex ring is provided with a first surface, a second surface and a third surface, and the second surface is covered on the sealing member, the third surface The system is disposed between the first side and the second side.

As we have previously known, the spindle structure used in the machine tool is used, such as Taiwan patent application number: 103404154, certificate number: M484044, patent name: machine tool spindle with gas power retaining device, one with gas power The tool spindle of the water retaining device comprises: a spindle seat, the center of which is provided with a rotatable rotating shaft center, and an air inlet passage is arranged in the wall surface of the spindle seat, and one end of the air inlet passage is connected to a gas source; And a dust cover disposed at an end of the rotating shaft, an air power passage is disposed between the dust cover and the spindle seat, and the air power channel is connected to the other end of the air inlet channel; wherein the gas The power channel is arranged along the radial direction of the spindle seat.

However, the missing structure of this conventional spindle structure is:

1. The dust cover 20 closes the gap between the front cover 14 of the main shaft, that is, the dust cover 20 and the front cover 14 of the main shaft are closed, but only the closed relationship between the dust cover 20 and the front cover 14 of the main shaft is provided, and the waterproof function is Will be insufficient.

2. Please supplement the seventh figure in the bulletin. The spindle structure needs to be connected to the intake passage 12. Gas source, generally, the gas source in the factory should basically be an air compressor. The air compressor is mostly located at the corner of the factory. The inlet passage 12 needs to be connected with a gas pipeline and compressed with air. The machine is connected, and the gas pipeline needs to have a certain length to connect to the corner of the factory, which requires considerable pipeline cost.

In view of the lack of the spindle structure mentioned above, the creator has been engaged in the manufacturing, production and design experience of related industries for many years, and finally has a product that can solve the drawbacks of the spindle structure.

The new problem to be solved: the spindle anti-liquid effect is quite limited.
