Concrete meaning in the present invention.
As shown in Figure 1, the figure shows the cross-sectional view of cutterhead cooling device top half of the invention, it is double below the figure
Chain-dotted line is the axis of the cutterhead cooling device.Cutterhead cooling device includes rotating disk 3, connection ring 4 and the first sealing ring 5.
Cutterhead 1 is rotatably installed on knife rest 2, and there are certain gap 6, the width in the gap 6 between cutterhead 1 and knife rest 2
Degree can be adjusted as needed, as long as guaranteeing the normal rotation of cutterhead 1.
With continued reference to Fig. 1, cutterhead cooling device further includes the first cooling duct 11 being arranged on cutterhead 1 and is arranged in knife
The second cooling duct 21 on frame 2.The left end of knife rest 2 is additionally provided with a looping pit (unused appended drawing reference marks in figure), rotation
Turntable 3 is mounted in the looping pit, and rotating disk 3 can be rotated around the central axis of knife rest 2.Preferably, rotating disk 3 and ring
Shape hole is tightly connected (for example, connecting by rotating seal).Knife rest 2 and rotating disk 3 define a toroidal cavity 23 jointly,
Second cooling duct 21 is connected to by fabrication hole 22 (need to seal in assembled state and block) with toroidal cavity 23.Or
Person, those skilled in the art can be with the second cooling duct of appropriate adjustment 21 or size and the positions of toroidal cavity 23, so that second
Cooling duct 21 can be directly connected to toroidal cavity 23.
As depicted in figs. 1 and 2, it is provided with another looping pit (unused appended drawing reference marks in figure) in rotating disk 3, connects
Ring 4 is axially slidably mounted in the looping pit, but connection ring 4 is fixed in the circumferential, cannot be 3 turns relative to rotating disk
It is dynamic.An annular through-hole 41 is provided in connection ring 4, when connection ring 4 is slided to the left and left end is contradicted onto cutterhead 1, annular
Through-hole 41 is connected to the first cooling duct 11, and then is connected to the first cooling duct 11 with the second cooling duct 21.Connection ring 4
It is provided on excircle an annular groove (unused appended drawing reference marks in figure), which makes for installing the first sealing ring 5
Obtaining connection ring 4 can be in sealing contact by the first sealing ring 5 and the inner wall of rotating disk 3, and then prevents the annular on 4 right side of connection ring
Coolant liquid in cavity 23 is gone out by the clearance leakage between connection ring 4 and rotating disk 3.Further, the right end axis of connection ring 4
An annular flange 42 is set up, it is preferable that the outer diameter of the annular flange 42 is less than the outer diameter of connection ring 4.By by ring
The right side of shape flange 42 is resisted against on the right side inner wall (right side of toroidal cavity 23 as shown in the figure) of toroidal cavity 23, so that
Toroidal cavity 23 and annular through-hole 41 completely cut off, to prevent coolant liquid from making by annular through-hole 41 when cutterhead 1 does not need be cooling
At leakage.
It will be appreciated to those of skill in the art that the first sealing ring 5 being mounted in connection ring 4 is not limited only to one,
It can also be multiple to reach better seal effect.
Preferably, settable third sealing ring (not shown) between annular flange 42 and toroidal cavity 23；More preferably
Ground is additionally provided with spring (not shown) between annular flange 42 and toroidal cavity 23, do not lead in the second cooling duct 21
When entering high-pressure coolant or lower coolant pressure, by spring by connection ring 4 retract to the right and by third sealing ring against
On the inner wall of toroidal cavity 23.Position shown in Fig. 2, i.e., spring still has certain elastic force under normality, in the work of the elastic force
Third sealing ring is compressed with lower connection ring 4, and then hermetically completely cuts off toroidal cavity 23 and annular through-hole 41.
With continued reference to Fig. 1 and Fig. 2, it is preferable that the settable second sealing ring (not shown) in the left end of connection ring 4, when
When needing to cool down cutterhead 1, the second cooling duct 21 is passed through high-pressure coolant, and high-pressure coolant applies one to connection ring 4
A pressure to the left pushes connection ring 4 to be moved to the left, simultaneously against the right side of cutterhead 1 when the pressure overcomes the elastic force of spring
The second sealing ring is compressed, to be connected to the first cooling duct 11 and the second cooling duct 21 by annular through-hole 41.
Illustrate the working principle of cutterhead cooling device of the invention below with reference to Fig. 1 and Fig. 2.When cutterhead 1 is in rotation
When needing cooling under state, it is passed through high-pressure coolant to the second cooling duct 21, when coolant liquid is applied to the pressure of 4 right end of connection ring
When power is enough to overcome the pulling force of spring, connection ring 4 is moved to the left, until in the right end face for abutting to cutterhead 1, at this time
One cooling duct 11 is connected to by annular through-hole 41 with the second cooling duct 21, and coolant liquid cools down cutterhead 1.More specifically
Ground, due to the presence of annular through-hole 41, no matter cutterhead 1 be it is static, be in rotation status, or what angle rotated to
Degree, when connection ring 4 is moved to the left in the right end face for abutting to cutterhead 1, the first cooling duct 11 can be logical by annular
Hole 41 is connected to the second cooling duct 21.When cutterhead 1 does not need be cooling, coolant liquid stops supplying to the second cooling duct 21,
Connection ring 4 moves right under the action of spring tension, until the right end of cutterhead 1 and connection ring 4 is left in the left end of connection ring 4
Until abutting on the right side inner wall of toroidal cavity 23, connection ring 4 compresses third sealing ring under the action of spring tension at this time,
And then seal isolation toroidal cavity 23 and channel 41.
It will be appreciated to those of skill in the art that a check valve can be arranged in annular through-hole 41 to replace spring
With third sealing ring, still, the connection ring 4 of such embodiment can not retract automatically, and 1 tool changing of cutterhead can be to connection when rotating
Ring 4 causes to wear.
It will be appreciated to those of skill in the art that gap 6 between cutterhead 1 and knife rest 2 is in the case where condition is permitted,
It should be made as small as possible, when needing cooling so as to cutterhead 1, connection ring 4 being capable of fast reaction, movement.
It should be noted that connection ring 4 uses wear-resistant material, metal wear resistant material is preferably used；Or connection ring 4 is adopted
Made with flexible rubber system, saves the first, second, and third sealing ring, the excircle of connection ring 4 is made into ripple
Shape, connection ring 4 two end faces be arranged V-shaped groove or by two end faces of connection ring 4 be made into it is annular corrugated so as to
Connection ring 4 can be in sealing contact with the right side of the right side of cutterhead 1 and toroidal cavity 23 respectively.
Those skilled in the art are also understood that coolant liquid can be water, group water solution, oil and oil-based solution.
So far, it has been combined preferred embodiment shown in the drawings and describes technical solution of the present invention, still, this field
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these specific embodiments.Without departing from this
Under the premise of the principle of invention, those skilled in the art can make equivalent change or replacement to the relevant technologies feature, these
Technical solution after change or replacement will fall within the scope of protection of the present invention.
