Abstract
The invention discloses a pressurized sealing water-proof and dust-proof anti-collision grinding head. The grinding head comprises a grinding head body and a main shaft, wherein the main shaft is mounted by adopting a single-orifice positioning structure and an end surface fixing anti-collision structure; in the single-orifice positioning structure, the rear end of a shaft sleeve is positioned in a rear inner hole in the grinding head body, and the rear end surface of the shaft sleeve is fixed on the grinding head body through a rear flange; in the end surface fixing anti-collision structure, the front end of the shaft sleeve is unmatched with a front inner hole in the grinding body, and the front end surface of the shaft sleeve is fixed on the grinding head body through a front flange; an upper radial adjusting screw, a lower radial adjusting screw, a left radial adjusting screw and a right radial adjusting screw are arranged on the grinding head body in a manner by surrounding the front end of the shaft sleeve; O-shaped rings at the front end and at the rear end of the sealing sleeve are mounted in a pressing manner between the front flange and the grinding head body and between the rear flange and the grinding head body; an air inlet communicated with a high-pressure air tube is formed in the grinding head body; a gas injecting hole penetrating out of the front end surface of the shaft sleeve is formed in the shaft sleeve. When the main shaft is collided during grinding, accuracy of the main shaft can be recovered by simply adjusting the radial adjusting screws; by adopting pressurized sealing, high-pressure coolant liquid, water mist, grit and other sundries in the grinding area are prevented from immersing into the bearing area at the front end of the main shaft.

It is the key obtaining high manufacturing accuracy, thereby ensure that the precision of main shaft is particularly important.
At present, commonly used two Internal hole positionings of the mounting means of grinding spindle, the mode of end face screw fastening.This positioning side
Formula has high demands to the perpendicularity of grinding head body two endoporus and end face, during bore hole, the axiality of grinding head body two endoporus it is difficult to ensure that, assembling
Main shaft and grinding head body stuck phenomenon in Shi Rongyi, and machining and assembly difficulty are big；On the other hand, if occurring during grinding clashing into,
Because using two Internal hole positionings, end face screw fastening means, main shaft precision is difficult to recover.
(3) content of the invention:
In place of the deficiencies in the prior art, it is an object of the invention to proposing a kind of rational in infrastructure, easy for installation, lead to
Cross the pressurized seal anti-water dust formula anticollision bistrique that adjustment can recover main shaft precision, the further mesh of the present invention is for preventing in grinding
During, the debris such as high-pressure coolant, water smoke, sand grains immerse front-end of spindle bearing area.
For reaching above-mentioned purpose, present invention employs technical scheme below:
Pressurized seal anti-water dust formula anticollision bistrique, including grinding head body and main shaft, described main shaft unlike the prior art
Including axle sleeve and shaft core, described shaft core passes through (rolling) bearing location and installation of axle sleeve two ends endoporus, and described main shaft adopts single hole
Location structure and the fixing Anti-collision structure of end face are installed on grinding head body.Described single hole location structure is the rear alignment of axle sleeve in mill
The rear endoporus of head body, axle sleeve rear end face is fixed on grinding head body by rear flange；The fixing Anti-collision structure of described end face is axle sleeve front end
No coordinate with the front endoporus of grinding head body, axle sleeve front end face is fixed on grinding head body by forward flange, around axle sleeve front end, set in grinding head body
Put four, upper and lower, left and right radiai adjustment screw.
In said structure, if occurring during grinding clashing into, forward flange need only be unclamped, main shaft position is adjusted by radiai adjustment screw
Put and can recover main shaft precision, after main shaft accuracy resumption, tighten forward flange.
The o shape circle of sealing axle sleeve front end is press-fited, between described rear flange and grinding head body between described forward flange and grinding head body
Press-fit the o shape circle of sealing axle sleeve rear end, thus make to be formed and axle sleeve between closed cavity inside grinding head body, described axle sleeve opens up
There is the fumarole of pass-out axle sleeve front end face；The air inlet of connection high-pressure air pipe is offered on described grinding head body, gases at high pressure enter
Afterwards, described closed cavity forms pressurized seal area, the dense gas of ejection formed airtight be encapsulated in axle sleeve front end face, effectively stop high
End bearing before the debris immersion shaft core such as pressure coolant, water smoke, sand grains.
Beneficial effects of the present invention:
1st, pressurized seal of the present invention anti-water dust formula anticollision bistrique fixes Anti-collision using the end face of single Internal hole positioning and uniqueness
Structure, front-end of spindle face no screw fastening means, reduction machine adds, assembly difficulty, meanwhile, equipped with for adjusting main shaft in grinding head body
The screw of precision, if occurring during grinding clashing into, need only can recover main shaft precision by screw adjustment, convenient, fast, significantly carry
High efficiency.
2nd, the present invention adopts pressurized seal technology, makes the high pressure gas that the external world is passed through form pressurized seal in bistrique intracoelomic cavity
Area, blocks the immersion of the debris such as the high-pressure coolant of grinding area, water smoke, sand grains, improves the life-span of rolling bearing and ensures master
The precision of axle.
(4) brief description:
Fig. 1 is the structural representation of one embodiment of the present invention.
Figure number identifies: 1, grinding head body；2nd, main shaft；3rd, radiai adjustment screw；4th, forward flange；5th, rear flange；6th, high-pressure air pipe；
7th, o shape circle；8th, emery wheel；9th, motor.
(5) specific embodiment:
Illustrated embodiment is described further to technical scheme below in conjunction with the accompanying drawings.
The technical scheme of pressurized seal of the present invention anti-water dust formula anticollision bistrique, including grinding head body 1 and main shaft 2, described bistrique
Body 1 is horizontal hollow structure, and the front and rear end of grinding head body 1 offers coaxial front endoporus and rear endoporus respectively；Described master
Axle 2 includes axle sleeve and shaft core, and described shaft core passes through the rolling bearing location and installation of axle sleeve two ends endoporus, and main shaft 2 adopts single hole fixed
Bit architecture and the fixing Anti-collision structure of end face are installed on grinding head body 1, and before shaft core, emery wheel 8, shaft core are installed in axle head projecting shaft set front end
Axle head projecting shaft is covered rear end and is connected the output shaft of motor 9 by shaft coupling, as shown in Figure 1 afterwards.
The single hole location structure that described main shaft 2 adopts is: the rear Internal hole positioning of the rear end of described axle sleeve and grinding head body 1 is joined
Close, axle sleeve rear end face is connected by screw mode by rear flange 5 and is fixed on grinding head body 1, as shown in Figure 1.
The fixing Anti-collision structure of end face that described main shaft 2 adopts is: the front endoporus of the front end of described axle sleeve and grinding head body 1 is no
Coordinate, that is, the front endoporus aperture of grinding head body 1 is more than the point diameter of axle sleeve, be the avoidance amount of bistrique anticollision, axle sleeve more than amount
Front end face is connected by screw mode by forward flange 4 and is fixed on grinding head body 1, around the circumference of axle sleeve front end, opens in grinding head body 1
If four, upper and lower, left and right radial screw hole, each radial screw in the hole is all combined with radiai adjustment screw 3, as shown in Figure 1.
O shape circle 7 is press-fited with sealing axle sleeve front end, described rear flange 5 and grinding head body 1 between described forward flange 4 and grinding head body 1
