Abstract
The utility model discloses an interior cold type drill point cover comprises a sealed piece, a main shaft, a hollow rotating shaft, a device of intaking, a water inlet, a spring drill point cover, a locking nut, a core drill, and the device of intake is installed in the periphery of main shaft, is equipped with a water inlet on the device of intaking, and the water inlet upper and lower respectively is equipped with a sealed piece, and the core drill is installed in spring drill point cover, fixes changeing epaxial through the locking nut, is equipped with the several apopore on the hollow boring bit, and this utility model structure is simple, make the drill bit increase, improve the processing quality service life.
Description
Technical field
The utility model relates to a kind of drill point cover, relates in particular to a kind of inner-cooled drill point cover, mainly answers mechanical processing industry.
Background technology
At present in mechanical processing industry, drill bit is a kind of cutter that often uses, but cooling fluid must be to be sprayed directly on on the drill bit in working angles, when drilling depth reaches 30 millimeters or when darker, cool off extremely insufficient, the drill edge part almost can not get cooling, the heat that cutting is produced can not spread out of fast, makes the blade temperature raise the reddening deliquescing, the operator is in order to make drill bit energy operate as normal, must frequently withdraw from drill bit, continue boring after the cooling again, so cutting speed be slow, efficient is low, bit wear is fast, the life-span is short, and labour intensity is big, crudy is poor.
The utility model content
In order to overcome the defective of above-mentioned prior art, the utility model provide a kind of simple in structure, make drilling life of bit increase, improve crudy.
The utility model is realized by following scheme, a kind of inner-cooled drill point cover, by sealing block, main shaft, hollow rotating shaft, water feed apparatus, water inlet, spring drill point cover, locking nut, the core drill apopore is formed, described water feed apparatus is installed in the periphery of main shaft, described water feed apparatus is provided with a water inlet, described water inlet respectively be provided with a sealing block up and down, described hollow rotating shaft is installed in the bottom of main shaft, described core drill is installed in the spring drill point cover, be fixed in the rotating shaft by locking nut, described hollow boring bit is provided with several apopores.
The utlity model has following beneficial effect in sum:
1, simple in structure, drilling life of bit is increased;
2, improve crudy.
Description of drawings
Fig. 1 is the explosion views of the utility model inner-cooled drill point cover;
Fig. 2 is the utility model core drill generalized section.
Wherein: 1-sealing block, 2-main shaft, 3-hollow rotating shaft, 4-water feed apparatus, 5-water inlet, 6-spring drill point cover, 7-locking nut, 8-core drill.
The specific embodiment
Shown in Fig. 1-2: a kind of inner-cooled drill point cover, by sealing block 1, main shaft 2, hollow rotating shaft 3, water feed apparatus 4, water inlet 5, spring drill point cover 6, locking nut 7, core drill 8, apopore 9 is formed, described water feed apparatus 4 is installed in the periphery of main shaft 2, described water feed apparatus 4 is provided with a water inlet 5, the water that is advanced is daily running water, described water inlet 5 respectively be provided with a sealing block 1 up and down, the water that enters is directly flow in the hollow rotating shaft 3, and can be from not flowing out between water feed apparatus 4 and the main shaft 2, described core drill 8 is installed in 6 li in spring drill point cover, be fixed on the hollow rotating shaft 3 by locking nut 7, the drill bit of described core drill 8 is provided with several apopores 9.
The utility model is to implement like this, at first core drill 8 is installed in the spring drill point cover 6, by locking nut 7 spring drill point cover 6 is being fixedly mounted on the hollow rotating shaft 3; Secondly water valve is opened, at this moment water will flow in the hollow rotating shaft 3 by the water inlet on the water feed apparatus 45, where can cool can realizing that drill bit gets into by interior cold mode by sky, also guarantee simultaneously the service life of drill bit, also can improve the precision that adds man-hour.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
Claims (2)
1. inner-cooled drill point cover, form by sealing block, main shaft, hollow rotating shaft, water feed apparatus, water inlet, spring drill point cover, locking nut, core drill, apopore, it is characterized in that: described water feed apparatus is installed in the periphery of main shaft, and described water feed apparatus is provided with a water inlet.
2. a kind of inner-cooled drill point cover according to claim 1 is characterized in that: described water inlet respectively be provided with a sealing block up and down.
