Abstract
The utility model provides a kind of dedicated sealing device of grinding wheel spindle, including end cap, the front end face of end cap is ladder-like, respectively first end face and second end face, first end face is higher than second end face, rear end face is also ladder-like, respectively third end face and the 4th end face, third end face is higher than the 4th end face, the third end face of rear end face is equipped with annular groove, sealing ring is installed, the sealing ring is compressed by clamp nut, and the rear end face of clamp nut and the 4th end face of end cap rear end face are concordant in annular groove.The anti-chip effect of the device waterproof is good, and sealing ring long service life reduces labour cost.
Description
Technical field
The utility model belongs to the grinding wheel machinery equipment field of grinding drill, and in particular to a kind of grinding wheel spindle is dedicated close
Seal apparatus.
Background technique
In the prior art, the end cap front surface installed on grinding wheel spindle be it is ladder-like, rear surface is tabular, in end cap and sand
Wheel shaft contact surface is equipped with the groove of installation sealing ring, and the grinding wheel spindle is in grinding process, due to the collective effect of water and chip,
Sealing ring service life is very short, and general two weeks just needs replacing once, if being changed without, one month, sealing ring is worn
Just can't see substantially, sealing performance at this time substantially reduces, chip be easy for enter grinding wheel spindle inside, bearing is caused to damage
Evil causes grinding wheel eccentric shaft, shakes and then grinding accuracy is caused to substantially reduce, therefore the grinding wheel spindle service life is short, more
It changes frequently, reduces working efficiency, increase cost.
Utility model content
To solve the above problems, the utility model provides a kind of dedicated sealing device of grinding wheel spindle, the device waterproof is anti-to be cut
Bits effect is good, and sealing ring long service life reduces labour cost.
The purpose of this utility model is achieved in that
A kind of dedicated sealing device of grinding wheel spindle, including end cap, the front end face of end cap are ladder-like, respectively first end face
And second end face, first end face are higher than second end face, rear end face is also ladder-like, respectively third end face and the 4th end face, the
Three end faces are higher than the 4th end face, and the third end face of rear end face is equipped with annular groove, is equipped with sealing ring in annular groove, described
Sealing ring is compressed by clamp nut, and the rear end face of clamp nut and the 4th end face of end cap rear end face are concordant.
End cap and grinding wheel spindle contact position are equipped with gap.
The thickness of the sealing ring is greater than the depth of annular groove.
Compared with the existing technology, in the utility model, the groove location of newly-designed end cap changes, while in groove
Sealing ring compressed by clamp nut, which can greatly improve the service life of sealing ring, waterproof and anti-chip
Effect it is more preferable, improve machining accuracy.
Detailed description of the invention
Fig. 1 is grinding wheel shaft seal in the prior art；
Fig. 2 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, end cap 103 in the prior art is being equipped with annular groove 102, annular with 101 contact position of grinding wheel spindle
Sealing ring is equipped in groove 102, during drill bit grinding, water and chip are easily accessible in the gap of grinding wheel spindle, and sealing ring is slow
Slowly it is consumed, after two weeks, sealing performance is substantially reduced, and after one month, is substantially not visible sealing ring.As shown in Fig. 2, this reality
Provide a kind of dedicated sealing device of grinding wheel spindle, including end cap 2 with novel, the front end face of end cap 2 be it is ladder-like, respectively the
One end face 201 and second end face 202, first end face 201 are higher than second end face 202, and rear end face is also ladder-like, respectively third
End face 203 and the 4th end face 204, third end face 203 are higher than the 4th end face 204, and the third end face 203 of rear end face is equipped with annular
Groove 4 is equipped with sealing ring 6 in annular groove 4, and the sealing ring 6 is compressed by clamp nut 3, the rear end face of clamp nut 3
301 is concordant with the 4th end face 204 of 2 rear end face of end cap.
End cap 2 and 1 contact position of grinding wheel spindle are equipped with gap 5.
The thickness of the sealing ring 6 is greater than the depth of annular groove 4.
The utility model has the following beneficial effects: sealing ring 6 to be pressed on to the third end face 203 of end cap 2 by clamp nut 3
Place, both can guarantee sealing performance, the anti-chip significant effect of waterproof, while can greatly increase the service life of sealing ring, existing skill
Sealing device in art just needs replacing once for one month, and the utility model passes through test, and half a year just needs replacing once.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these also should be considered as
The protection scope of the utility model.
