Description
Technical Field
The invention belongs to the field of machining, and particularly relates to an anti-deflection annular nozzle capable of quickly stopping water.
Background
In the process of machining the numerical control machine tool, in order to prolong the service life of a cutter and improve the machining precision of a workpiece, the cutter and the workpiece need to be cooled. Because the annular nozzle can realize 360 degrees all-round cooling, the cooling effect is good and is applied to the occasion that high accuracy processing required more and more. The existing annular nozzle structure is that a certain number of water outlets are arranged at the bottom of an annular flow passage, and then a metal pipe high-pressure nozzle or a bamboo joint type nozzle is inserted into the water outlets, and firstly, the metal pipe high-pressure nozzle or the bamboo joint type nozzle occupies a large space, and interference is easy to occur when a main shaft automatically changes a tool; secondly, because the annular nozzle is contacted with cutting fluid and cutting chips for a long time, after the annular nozzle is used for a period of time, the sealing element inside the annular nozzle is abraded, so that the inserting part is loosened, the metal pipe high-pressure nozzle or the bamboo joint type nozzle can deflect to one side by the reverse thrust generated when the liquid is sprayed out of the metal pipe high-pressure nozzle or the bamboo joint type nozzle, the cutting fluid cannot be conveyed to the correct position, and the structure cannot be used for independently replacing the sealing element, only can be used for replacing the nozzle, and has higher cost; in addition, the cutting fluid remained in the nozzle can continuously drop after the fluid supply pump stops supplying fluid to the annular nozzle, the cutter handle is easily polluted in the process of changing the cutter of the spindle, and the precision of the spindle can be influenced if the spindle enters the spindle taper hole carelessly.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides the anti-deflection annular nozzle which is simple in structure, small in occupied space, not prone to interference and capable of rapidly stopping water.
In order to solve the technical problems, the invention is realized by the following technical scheme: a deflection-preventing annular nozzle capable of quickly stopping water consists of a sectional annular runner and a plurality of three-way nozzles, wherein the three-way nozzles are respectively arranged between the two sectional annular runners and form an annular water containing cavity together with the sectional annular runners; the three-way nozzle comprises a runner part and a liquid spraying part, wherein the runner part and the liquid spraying part are vertically arranged to form a three-way structure, openings at two ends of the runner part are respectively communicated with the sectional annular runner, the upper end of the liquid spraying part extends into the runner part and is higher than the inner wall of the runner part, and an opening at the lower end of the liquid spraying part sprays liquid to a cooling target; the three-way nozzle can rotate around the central axis of the channel part in the sectional annular channel, so that the spraying angle of the liquid spraying part can be changed.
According to the anti-deflection annular nozzle capable of quickly stopping water, the sealing device is arranged between the three-way nozzle and the sectional annular flow channel.
The segmented annular flow channel is provided with the liquid inlet, and the liquid inlet is connected with the liquid supply device to supply cutting liquid into the annular water containing cavity.
Compared with the prior art, the invention has the beneficial effects that: the invention adopts the structure form that the three-way nozzle is communicated with the sectional annular flow passage, not only can realize the free adjustment of the angle of the nozzle, but also has small and exquisite nozzle structure, and greatly reduces the space occupation of the annular nozzle; and by utilizing the principle of a communicating vessel, the liquid spraying part of the three-way nozzle extends inwards, so that the nozzle and the cutting liquid remained in the pipeline can be sealed in the pipeline while the liquid supply pump stops supplying the liquid, and the cutting liquid is prevented from dripping. In addition, the counterforce generated by the cutting fluid sprayed by the liquid spraying part passes through the rotation center of the three-way nozzle, so that deflection is avoided, and the influence of the counterforce on the liquid spraying direction is effectively avoided. The three-way type nozzle adopts a detachable structure, and the sealing element can be replaced independently, so that the use cost is greatly reduced.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Fig. 2 is a schematic diagram of the internal structure of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 and 2, the anti-deflection annular nozzle capable of rapidly stopping water according to the present invention comprises a segmented annular flow passage 1 and a three-way nozzle 2, wherein the three-way nozzle 2 is respectively disposed between the two segmented annular flow passages 1, and forms an annular water containing cavity together with the segmented annular flow passage 1, and a sealing device 3 is disposed between the three-way nozzle 2 and the segmented annular flow passage 1 to ensure the internal sealing of the annular water containing cavity. A liquid inlet 4 is arranged on the sectional type annular flow passage 1, and the liquid inlet 4 is connected with a liquid supply device to supply cutting liquid into the annular water containing cavity.
The three-way nozzle 2 comprises a channel part 21 and a liquid spraying part 22, wherein the channel part 21 and the liquid spraying part 22 are vertically arranged to form a three-way structure, openings at two ends of the channel part 21 are respectively communicated with the sectional annular channel 1, the upper end of the liquid spraying part 22 extends into the channel part 21 and is higher than the inner wall of the channel part 21, and the lower end opening of the liquid spraying part 22 sprays liquid to a cooling target. The three-way nozzle 2 can rotate around the central axis of the runner part 21 in the sectional annular runner 1, and the liquid spraying angle can be adjusted by adjusting the rotation angle.
Because the central axis of the liquid ejecting part 22 intersects with the central axis of the flow channel part 21, the reaction force generated when the liquid ejecting part 22 ejects liquid passes through the central axis of the flow channel part 21, namely the rotation center of the three-way type nozzle 2, the three-way type nozzle 2 does not deflect, and the influence of the reaction force on the liquid ejecting direction is effectively avoided.
Because the upper end of the liquid spraying part 22 is higher than the inner wall of the flow channel part 21, under the communication action, the liquid supply pump stops supplying liquid, and meanwhile, the cutting liquid remained in the three-way type nozzle 2 and the sectional type annular flow channel 1 is sealed in the pipeline, so that the cutting liquid is prevented from dropping.
Although the present invention has been described in detail hereinabove, the present invention is not limited thereto, and those skilled in the art can make various modifications in accordance with the principle of the present invention. Thus, modifications made in accordance with the principles of the present invention should be understood to fall within the scope of the present invention.
