Detailed Description

The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.

As shown in fig. 1-5, in an embodiment, a numerically-controlled machine tool free of cutting fluid is provided, which includes a numerically-controlled machine tool spindle 2 and a heat-shrinkable air ring 1, wherein the heat-shrinkable air ring 1 is sleeved on the numerically-controlled machine tool spindle 2, and a plurality of wind tunnels 11 are formed in the heat-shrinkable air ring 1.

The processed heat-shrinkable air ring 1 is sleeved on the numerical control machine main shaft 2, and the heat-shrinkable air ring 1 is shrunk on the numerical control machine main shaft 2 through heating, so that the installation of the heat-shrinkable air ring 1 is completed. When the numerical control machine main shaft 2 starts to rotate, the heat-shrinkable wind ring 1 also rotates, the lower end direction of the wind tunnel 11 is inclined towards the direction of the numerical control machine main shaft 2, and the upper end direction of the wind tunnel 11 is inclined towards the opposite direction of the numerical control machine main shaft 2, because of the arrangement, air can be sucked from the upper opening of the wind tunnel 11 when the heat-shrinkable wind ring 1 rotates, and then blown out from the lower opening, and dust on a machined workpiece 3 is blown away by the downward blown-out air, so that a worker can observe the workpiece 3 more intuitively and conveniently, cutting fluid can be fully replaced, and the production and machining cost is reduced.

Further, the wind tunnel 11 is communicated with the top of the heat-shrinkable wind ring 1 through an upper opening 111, the wind tunnel 11 is communicated with the bottom of the heat-shrinkable wind ring 1 through a lower opening 112, and the aperture of the upper opening 111 is larger than that of the lower opening 112. The upper opening 111 has a large aperture so as to be convenient for sucking more air, and the lower opening 112 has a small aperture so as to collect the air and accelerate the blowing out, thereby having better cleaning effect.

Further, the numerically-controlled machine tool spindle 2 comprises a spindle end 21, a spindle cutter bar 22 and a cutter 23, the spindle cutter bar 22 is fixed at the bottom of the spindle end 21, the cutter 23 is fixed at the bottom of the spindle cutter bar 22, and the heat-shrinkable air ring 1 is sleeved on the spindle end 21.

Further, the wind tunnel 11 is disposed obliquely, and the lower port 112 is disposed closer to the spindle head 21 than the upper port 111.
