Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-4, the dense-tooth hard alloy end mill with light cutting force comprises a milling cutter body 1, wherein the milling cutter body 1 comprises a cutter body 11 and a cutter head 12, one end of the cutter head 12 is fixed with one end of the cutter body 11, the cross section of the cutter body 11 and the cross section of the cutter head 12 are both circular, and the diameter of the cross section of the cutter body 11 is 1.3-1.5 times that of the cross section of the cutter head 12. In this embodiment, the diameter of the cross-section of blade 11 is 1.3 times the diameter of the cross-section of cutting head 12. The blade 11 is collinear with the central axis of the cutting head 12.
A plurality of first through-holes 2 are seted up to the bottom of blade 11, and the other end of first through-hole 2 runs through to the outside of blade 11. One end of the first through hole 2 close to the cutter head 12 is provided with a slope 21, and the slopes 21 are inclined towards the cutter head 12. The filter screen 4 is arranged inside the slope 21. When the liquid in the first through hole 2 flows downwards, the liquid can be sprayed to the surface of the cutter head 12, the problem of the surface of the cutter head 12 is reduced, and the service life of the cutter head 12 is prolonged. The ramp 21 allows more liquid to contact the surface of the cutting head 12, reducing waste of resources.
The upper half part of the outer peripheral surface of the cutter body 11 is provided with an oil storage shell 3. The oil storage shell 3 is internally provided with cooling liquid. One end of the first through holes 2 far away from the cutter head 12 is located inside the oil storage shell 3, and the inside of the oil storage shell 3 is communicated with the inside of the first through holes 2.
The outer peripheral surface of the oil storage shell 3 is provided with a second through hole 31, and a plug 32 is arranged at the second through hole 31.
A reset component 5 is arranged in one end of the first through hole 2 far away from the cutter head 12;
the resetting component 5 comprises a baffle 51, a first placing groove 52 is formed in one side, away from the inner wall of the tool bit 12, of the first through hole 2, and the first placing groove 52 is communicated with the interior of the first through hole 2;
the baffle plate 51 is arranged on the first through hole 2 and the first placing groove 52 in a sliding mode, a guide rod 53 is fixed on one side of the inner wall of the first placing groove 52, one end of the guide rod 53 extends into the baffle plate 51, the baffle plate 51 is connected with the guide rod 53 in a sliding mode, a spring 54 is sleeved on the outer peripheral surface of the guide rod 53, and two ends of the spring 54 are fixed with one end of the baffle plate 51 and one side of the inner wall of the first placing groove 52 respectively.
The lower half part of the outer peripheral surface of the cutter body 11 is provided with a chip groove 6, and one end of the chip groove 6 penetrates through the bottom of the cutter body 11.
The specific work content is as follows:
when the milling cutter body 1 rotates, the baffle 51 on the milling cutter body is driven to rotate together. When the spring 54 is in a natural state, the baffle 51 completely blocks one end of the first through hole 2, and the liquid in the oil reservoir housing 3 cannot flow into the surface of the cutter head 12 through the first through hole 2. The stop plate 51 defines that the direction of rotation of the milling cutter body 1 is fixed when rotating together with the milling cutter body 1 in the present embodiment. Due to the centrifugal force, the baffle 51 slowly moves along the linear direction of the guide rod 53, and the baffle 51 moves towards the first placing groove 52. As the spring 54 is compressively deformed, the baffle plate 51 cannot completely close one end of the first through hole 2, and the coolant inside the oil reservoir housing 3 enters the inside of the first through hole 2 and is finally sprayed on the surface of the cutter head 12.
When the milling cutter body 1 stops rotating, the spring 54 brings the stopper 51 back to the initial position due to the elastic restoring force of the spring 54. The shutter 51 completely closes one end opening of the first through-hole 2. The coolant inside the oil reservoir casing 3 cannot enter the inside of the first through-hole 2.
In addition, when the milling cutter body 1 is operated, the iron pieces move out of the working area through the chip flutes 6.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
