Description
Technical field
The application belongs to mechanical cleaning technical field, particularly relates to a kind of high-pressure wash nozzle.
Background technology
At Aero-Space precision component, auto parts and components (steering pump, bent axle etc.), construction implement and the machinery of other industry
In device, there is various blind hole, deep hole, deep friendship fork blind hole.According to producing precision and the requirement of service precision, blind hole, deep hole, deep
After blind hole etc. of intersecting machines, need to clean to remove flash removed, greasy dirt etc..Prior art uses jetting machine injection height
Setting-out cleans burr.Water under high pressure sprays to burr through the nozzle of jetting machine, and burr is washed away removal.
Fig. 1 show a kind of high-pressure spray gun sectional view, and its structure includes spraygun body 1 and tip body 2.Spraygun body
1 is provided with pod apertures 11.Tip body 2 is provided with the conduction hole 21 and spray-hole 22 being interconnected.Tip body 2 is installed
In spraygun body 1 end, pod apertures 11 connects with conduction hole 21, and conduction hole 21 axis is identical or flat with pod apertures 11 axis
OK, both axis are all vertical with spray-hole 22 axis.Spraygun body 1 connects, by height with high service device (not shown)
Pressure water supply installation provides water under high pressure.Water under high pressure is sprayed by spray-hole 22 after pod apertures 11, conduction hole 21.
Fig. 2 is the blind hole structure schematic diagram that one of which needs to clean.This blind hole includes orthogonal vertical core 31 and horizontal stroke
Hole 32 is constituted.As the inwall of cross-drilled hole 32 need to be cleaned, need to stretch to make its spray-hole 22 towards horizontal stroke from vertical core 31 by tip body 2
The position in hole 32.It is internal that water under high pressure sprays to cross-drilled hole 32 successively after pod apertures 11, conduction hole 21 and spray-hole 22.Shown in Fig. 1
Nozzle head, its conduction hole 21 axis is vertical with spray-hole 22 axis, at High-Pressure Water through conduction hole 21 and spray-hole 22 intersection
Time, water under high pressure rebounds after clashing into conduction hole inwall 211, and the current after bounce-back are contrary with the approach axis of water under high pressure, cause height
The pressure loss of setting-out is relatively big, and the water under high pressure sprayed through spray-hole 22 cannot accurately control.Owing to water under high pressure is through conduction hole inwall
Mutually clash into the water under high pressure entered in conduction hole 22 after 211 bounce-backs so that jet occurs in the water under high pressure sprayed through spray-hole 22
Scattered phenomenon, the tapered injection of jet, irradiation angle reaches 15 °-20 °.Spray dispersion cause jet cannot concentrated stress, shadow
Ring cleaning performance.In the case of water under high pressure direct-injection, owing to jet easily dissipates, the dead angle such as edge or male and female face can produce clearly
Wash blind spot, cause product burr to remove completely.Owing to conduction hole 21 axis is vertical with spray-hole 22 axis, conduction hole inwall
211 is vertical with the input direction of water under high pressure, and the frontal impact by water under high pressure, this structure also can be led by conduction hole inwall 211
Relatively greatly and reaction is also big to cause tip body 2 stress, causes spray gun entirety to have bigger change during water flow jet
Shape, is unfavorable for using for a long time.Similar structures is without guide functions, and the centralized procedure of a fluid stream can cause the pressure loss, and the pressure loss
Relatively big, the expulsion pressure of jet is had an impact.
