Description
Technical field
The utility model relates to a kind of main axle cutter cooling structure.
Background technology
Brill is attacked owner's axle and is installed in main spindle box, main shaft comprises body, axle core and bottom end cover, axle core is arranged in body, and bottom end cover is arranged at below axle core, below axle core, cutter is housed, for high rotating speed, high-precision main shaft, generally on main shaft, arrange cutter cooling structure, the cooling liquid outlet of existing cutter cooling structure is generally arranged on bottom end cover, but, for the main shaft of brachyrhinia end, bottom end cover thinner thickness, there is no sufficient space at bottom end cover place design cooling liquid outlet.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of.
For achieving the above object, the utility model adopts following technical scheme:
Main axle cutter cooling structure, comprise body, axle core and bottom end cover, axle core is installed on internal body, bottom end cover to be set on axle core and to be fixed on below body, the lateral surface of body is provided with the cannelure being communicated in main spindle box cooling fluid entrance, internal body is provided with cooling duct, body lower surface is provided with liqiud outlet head, body is provided with ball-and-socket, liqiud outlet head is provided with the bulb coordinated with ball-and-socket, liqiud outlet head is provided with out fluid through-hole and liqiud outlet head is positioned on the side of bottom end cover away from axle core, and the two ends of cooling duct are communicated with cannelure respectively and go out fluid through-hole.
The quantity of liqiud outlet head has multiple, and multiple liqiud outlet head is uniformly distributed along the circumference of axle core.
Cooling duct is connected to the lower end of cannelure.
Body is provided with Connection Block, and the medial surface of Connection Block is provided with described ball-and-socket, and the lateral surface of liqiud outlet head is provided with described bulb.
The beneficial effects of the utility model are:
Compared to prior art, the utility model main axle cutter cooling structure by arranging cannelure, cooling duct and liqiud outlet head on body, solves brachyrhinia end, a difficult problem that the main shaft of bottom end cover thinner thickness cannot offer liquid outlet on bottom end cover.Moreover liqiud outlet head is connected on the ball-and-socket of body by bulb, the spray angle of fluid through-hole can be adjusted, and go for the cutter of different length.In this structure, the heat produced when main shaft bearing runs up effectively can be taken away in the cooling duct that cutting fluid flows through internal body, significantly improves the heat endurance of boring and attacking owner's axle, ensures the high accuracy of main shaft, meanwhile, positive effect is also had to the life-span extending main shaft bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 10, body; 11, cannelure; 12, cooling duct; 13, liqiud outlet head; 131, fluid through-hole is gone out; 14, Connection Block; 20, axle core; 30, bottom end cover; 40, main spindle box; 41, cooling fluid entrance.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
As shown in Figure 1, main axle cutter cooling structure of the present utility model comprises body 10, axle core 20 and bottom end cover 30, it is inner that axle core 20 is installed on body 10, bottom end cover 30 to be set on axle core 20 and to be fixed on below body 10, the lateral surface of body 10 is provided with the cannelure 11 of the cooling fluid entrance 41 being communicated in main spindle box 40, body 10 inside is provided with cooling duct 12, body 10 lower surface is provided with liqiud outlet head 13, body 10 is provided with ball-and-socket, liqiud outlet head 13 is provided with the bulb coordinated with ball-and-socket, liqiud outlet head 13 is provided with out fluid through-hole 131 and liqiud outlet head 13 is positioned on the side of bottom end cover 30 away from axle core 20, the two ends of cooling duct 12 are communicated with cannelure 11 respectively and go out fluid through-hole 131.
Operationally, cooling fluid enters from the cooling fluid entrance 41 of main spindle box 40 main shaft, arrives cannelure 11, cooling fluid is under the effect of pressure and gravity, behind cooling duct 12, spray from the fluid through-hole 131 that goes out of body 10 lower end, thus cooling fluid is sprayed onto be fixed on axle core 20 lower end cutter on.Main axle cutter cooling structure of the present utility model by arranging cannelure 11, cooling duct 12 and liqiud outlet head 13 on body 10, solves brachyrhinia end, a difficult problem that the main shaft of bottom end cover 30 thinner thickness cannot offer liquid outlet on bottom end cover 30.
Moreover liqiud outlet head 13 is connected on the ball-and-socket of body 10 by bulb, can adjust the spray angle of fluid through-hole 131, and goes for the cutter of different length.
In this structure, the heat produced when main shaft bearing runs up effectively can be taken away in the cooling duct 12 that cutting fluid flows through body 10 inside, significantly improves the heat endurance of boring and attacking owner's axle, ensures the high accuracy of main shaft, meanwhile, positive effect is also had to the life-span extending main shaft bearing.
Further, the quantity of liqiud outlet head 13 has multiple, and multiple liqiud outlet head 13 is uniformly distributed along the circumference of axle core 20, can cool cutter more equably like this.
Further, cooling duct 12 is connected to the lower end of cannelure 11, like this, after cooling fluid enters cannelure 11, under the effect of pressure and cooling fluid self gravitation, be more prone to flow to cooling duct 12 from cannelure 11, the impurity of cutting fluid is not easy to be accumulated in cannelure 11, makes cooling duct unimpeded.
Further, body 10 is provided with Connection Block 14, the medial surface of Connection Block 14 is provided with ball-and-socket, and the lateral surface of liqiud outlet head 13 is provided with bulb.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
