Description
Technical field
The present invention relates to a kind of water cutting machine, more particularly to a kind of novel high-precision high-pressure water cutting head.
Background technology
High-pressure water cutting head is an important component of water cutting machine, and its effect is to be converted into the pressure energy of water under high pressure
The kinetic energy of high-speed water jet is used for the workpiece of the various materials of cutting processing.In cutting head part：(operating) water nozzle, mulling room and sand blasting
Pipe belongs to consumable accessory, it is necessary to regularly replace.Change consumable accessory during only the sand blasting pipe of guaranteed cutting head position not
Become, just can guarantee that the cutting processing precision of cutting head.In existing cutting header structure, sprayer body is joined with connecting tube by screw thread
Connect；Connecting tube and high pressure water switch are also by thread connection, when changing (operating) water nozzle and mulling room, it is necessary to remove sprayer body and company
Thread connection between adapter, due to the presence of thread pitch, therefore, when changing consumable accessory, the cutting head of such a structure without
Method ensures that the position of sand blasting pipe is constant.
Five axle water cutting machines of high accuracy are mainly used in the accurate cutting of variously-shaped workpiece, cutting head attitude-control device
Precision is to ensure the basis of five axle water cutting machine cutting processing precision.In five axle water cutting machines carried out with the center of cutting head
Programming, one changes when the position of sand blasting pipe, directly affects the precision of cutting head attitude-control device.Therefore, in five axles
In water cutting machine, it is ensured that the position of sand blasting pipe is constant particularly important in consumable accessory Renewal process.
The content of the invention
It is an object of the invention to provide a kind of novel high-precision high-pressure water cutting head, it can reduce changes in consumable accessory
During sand blasting pipe change in location.
The present invention above-mentioned technical purpose technical scheme is that：
A kind of novel high-precision high-pressure water cutting head, including sprayer body, (operating) water nozzle, mulling room, sand blasting pipe, sand-feeding tube and high pressure
Be provided with collet in taps, the inner chamber of the sprayer body lower end, the collet include hollow cylinder and
The hollow nose cone that cylinder lower end is set, the inner chamber of the cylinder one end and sprayer body away from nose cone coordinates embedding
Cover, and its outer wall is fixedly connected by chuck clamping nut with sprayer body；The (operating) water nozzle, mulling room and sand blasting pipe are matched somebody with somebody successively
Trap is located in collet, and the sand blasting pipe is stretched out outside collet；Sand blasting pipe pressure is arranged with outside the nose cone
Tight nut, the cylindrical end that the sand blasting pipe clamping nut includes and cylinder is threadedly coupled and the circle with nose cone compression laminating
Tapered end.
It is to be nested by such scheme, between the inner chamber of sand blasting pipe and collet, collet and sprayer body,
It is solid by chuck clamping nut between collet and sprayer body so as to ensure that the axiality between sand blasting pipe and sprayer body
It is fixed, so as to ensure that the positional precision between collet and sprayer body；Sand blasting pipe clamping nut is enclosed on outside nose cone, and its
The internal conical surface of conical end compresses nose cone, and during it is screwed with collet screw thread, conical end will pressure cone
Head inwardly produces a small amount of deformation, connects so that being formed closely to coordinate between the sand blasting pipe that nose cone and its internal engagement are set
Connect, sand blasting pipe is fixed, so as to improve the positional precision of sand blasting pipe, reduce its position change in consumable accessory Renewal process
Change.
Further, the shaft shoulder, described chuck clamping nut one end and shaft shoulder clamping are provided with the cylindrical sidewall, separately
One end and sprayer body threaded connection；When chuck clamping nut compress sprayer body and and sprayer body be fastenedly connected when, the (operating) water nozzle
Contradicted with shower nozzle intracoelomic cavity, the collet end face and shower nozzle intracoelomic cavity have gap.
By such scheme, the end face of (operating) water nozzle and inner chamber is closely contradicted, and is then compressed using collet, and is led to
Cross chuck clamping nut to fix collet and sprayer body, improve the position essence between (operating) water nozzle, mulling room and sprayer body
Degree, and then also just improve the positional precision of the sand blasting pipe directly contacted with mulling room.Between collet end face and inner chamber
Gap, which can allow, realizes benign contact between (operating) water nozzle and inner chamber.
Further, the nose cone is circumferentially high is evenly equipped with some necking grooves, and the necking groove is along nose cone
Axis direction is set.
By such scheme, during the setting of necking groove make it that sand blasting pipe clamping nut is screwed, nose cone can be
Inwardly deformed upon under the extruding of sand blasting pipe clamping nut, so that sand blasting pipe be compressed.
Further, the cylindrical end outer wall is provided with spanner groove.
By such scheme, spanner groove is easy to screw sand blasting pipe clamping nut by spanner, it is ensured that collet is to sand blasting
The clamping force of pipe.
Further, the nose cone is provided with the face of cylinder that diameter is less than cylinder close to a side wall of cylinder.
By such scheme, being provided for of the face of cylinder is avoided in installation process in the screw thread of sand blasting pipe clamping nut
The interference produced between footpath and collet.
Further, the junction of nose cone and cylinder is provided with escape.
By such scheme, escape can reduce the wall thickness of collet, be easy to when screwing sand blasting pipe clamping nut,
The conical end of spring joint is deformed.
Further, the collet upper end side wall is provided with the mounting hole inserted for sand-feeding tube.
By such scheme, mounting hole facilitates the installation of sand-feeding tube.
In summary, the invention has the advantages that：
It is to be nested between the inner chamber of sand blasting pipe and collet, collet and sprayer body, so as to ensure that sand blasting pipe
Axiality between sprayer body, is fixed between collet and sprayer body by chuck clamping nut, so as to ensure that spring
Positional precision between chuck and sprayer body；Outside sand blasting pipe clamping nut set and nose cone, and the internal conical surface of its conical end
Compress nose cone, during it is screwed with collet screw thread, conical end will pressure cone head inwardly produce a small amount of shape
Become, be closely connected so that being formed between the sand blasting pipe that nose cone and its internal engagement are set, sand blasting pipe is fixed
Firmly, so as to improve the positional precision of sand blasting pipe, its change in location in consumable accessory Renewal process is reduced.
