Description
Technical field
The utility model is related to a kind of CNC high-pressure cleaning machine, a kind of especially CNC high-pressure cleaning machine main axle structure.
Background technology
The main shaft task summary of CNC high-pressure cleaning machine is to enter rotation from booster pump high-pressure cleaning liquid after supercharged
Turn main shaft, main shaft is needed in the state of ensureing not let out cleaning fluid pressure, is transported to nozzle.And main shaft rotation position and rotary speed
It needs by Serve Motor Control, to control the position of nozzle delivery port, surface cleaning is carried out to part exactly.Currently on the market
Numerically-controlled machine tool main shaft using main-shaft core water outlet, the rotation of belt transmission main shaft.There are water flowing out structure to answer for this main axle structure
Miscellaneous, the shortcomings of discharge pressure is small, of high cost, rotational positioning low precision.
Utility model content
The purpose of this utility model is that existing CNC high-pressure cleaning machine main shaft is improved, especially to numerical control height
Pressure cleaning machine main axle structure is improved, and design is improved to the overall structure of main shaft.
In order to achieve the above objectives, the scheme for the solution that the utility model is taken is：A kind of CNC high-pressure cleaning machine main shaft knot
Structure, it includes axle sleeve and shaft core, and shaft core is inserted in axle sleeve from above, and axle sleeve lower part is provided with into water port, two rotating seal ring difference
In two grooves of axle sleeve, the upper-lower position into water port is respectively at, 6907 bearings and 61910 bearings are being pacified respectively
In axle sleeve, 6907 bearings are on the rotating seal ring of upper one, and 61910 bearings are in the rotating seal ring of next
Under, shaft-cup is fixed on axle sleeve in the following, two rows of angular contact bearings are placed in shaft core and in the space on axle sleeve top, bearing gland is fixed
On axle sleeve, locking nut is inserted in shaft core and locks, and nozzle is fixed below shaft core.
The nozzle is a shaft member with multiple steps, and there is hole in centre, passes at small end 2mm, at small end 2mm
Warp-wise is communicated there are one hole with in-between hole., it can be achieved that rotary water jet after main shaft rotation.
It installs order：Rotating seal ring is mounted in two grooves of axle sleeve by the first step；Second step is by 6907 axis
It holds in axle sleeve；Shaft core is installed into axle sleeve by the 3rd step；4th step installs 61910 bearings；5th step installs shaft-cup；The
Six steps install angular contact bearing；7th step installs bearing gland；8th step installs bearing washer；9th step locks locking nut；
Tenth step installs nozzle.
This kind of CNC high-pressure cleaning machine main axle structure operation principle：High-pressure cleaning liquid is pressurized to by being evacuated to booster pump in water tank
60MPa enters shaft core from main shaft sleeve side wall inlet opening, is transported to nozzle, realizes high-pressure wash work.The shaft core top of main shaft
It is driven by motor direct connection, main shaft rotation, the angle of control main shaft water spray position.
The main axle structure feature of this kind of CNC high-pressure cleaning machine：First, by the way of direct connection main shaft is driven to rotate, improves rotation
Turn positioning accuracy；2nd, cleaning solution enters main shaft shaft core from the side wall of shaft sleeve inlet opening of main shaft, and being respectively equipped with up and down for water inlet can
The rotating seal ring of 60mpa pressure is born, ensures the pressure of cleaning solution；3rd, upper rotating seal ring and lower rotating seal ring is upper
Under using installation deep groove ball bearing, effectively reduced cost under conditions of warp-wise stress is ensured
This kind of CNC high-pressure cleaning machine main axle structure compared with prior art, has the positive effect that：Main axle structure
Simply, it is easy for installation, of low cost, discharge pressure is high, rotational positioning precision is high.
