Abstract

The utility model relates to a spray nozzle which comprises a main body; a feeding port and a jet orifice are arranged on both ends of the main body; the end face of the jet orifice is provided with a strip-shaped arc surface, so that the spray nozzle is matched with a work piece, can be used to spray fluid on the cylindrical bar-shaped work piece, and has the advantage of quite uniform fluid spraying.

Description

Nozzle arrangements

Technical field

The utility model is about a kind of nozzle arrangements, refers in particular to have to make the flow of fluid fluid when spraying can equally distributed structure.

Background technology

Referring to shown in Figure 4, the nozzle that is a prior art is used to spray the enforcement schematic diagram of fluid in the spiro tooth part 20 of a workpiece, in a nozzle, include a body 30, this body 30 is a hollow circular tube, it is formed with a feeding mouth 32 and a jet 31 respectively at two ends, the nozzle 30 of the prior art is when using, position with its jet 31 desire spraying fluid on spiro tooth part 20, and fluid enters this body 30 via feeding mouth 32, and then by these jet 31 ejections, and be coated on spiro tooth part 20 surfaces, generally speaking, the area of desire spraying fluid can be greater than the area of this jet 31, so nozzle 30 or workpiece can move, and makes fluid can be sprayed into the position of all desires sprayings.

Yet, because the nozzle of the prior art, it is formed with the end face of jet 31, be plane, therefore plane to the distance that is formed at spiro tooth part 20 surfaces on the workpiece round bar of this jet 31 is not equidistant because of the position is different, therefore this nozzle is in order to spray fluid in spiro tooth part 20, when perhaps other is on the workpiece of round bar shape, tend to accumulate more fluid apart from jet 31 nearer positions, and it is less away from the Fluid Volume on the position of jet 31, cause fluid coating thickness and inhomogeneous, and in the control of spraying processing procedure, bring inconvenience.

Summary of the invention

Because aforementioned the deficiencies in the prior art point, the utility model provides a kind of nozzle arrangements, has a jet that is banded cambered surface, and the phase can solve the nozzle of prior art, in order to the spraying fluid when the round bar shape workpiece, fluid shortcoming pockety.

For reaching the foregoing invention purpose, the employed technological means of the utility model is for providing a nozzle arrangements, this nozzle arrangements includes a body, this body is a hollow, and be formed with a feeding mouth and a jet respectively in two ends, wherein, be formed with the end surface shape of this jet, be banded cambered surface.

Advantage of the present utility model is, owing to the opening shape of this jet is to cooperate the workpiece profile to be arc surfaced, comparatively average by each position of jet end face to the distance of workpiece end face, therefore nozzle arrangements of the present utility model is used to spray fluid when spiro tooth part or the like is on the workpiece of round bar shape, can avoid fluid to concentrate and be sprayed at some position, can reach the purpose that makes the fluid distribution uniform.

The specific embodiment

Referring to shown in Figure 1, nozzle arrangements of the present utility model includes a body 10, wherein:

This body 10 is a hollow, its opening part in an end is formed with a feeding mouth 12, the cross section of this feeding mouth 12 is rounded, and the wall of body 10 extends out and forms rectangle by feeding mouth 12 places gradually towards the other end, and be formed with a rectangular jet 11 in this end opening place, two relative walls of this end also contract in opening part and are an arcuation, make the end face of this jet 11 be a banded cambered surface, be on the workpiece of round bar shape and can be used in fluid being sprayed at one, and should the band shape cambered surface can be according to the profile difference of workpiece, and be designed to different radians.

Nozzle arrangements of the present utility model, it sprays the position of fluid with aforementioned jet 11 desire on workpiece when using, and fluid enters in body 10 via aforementioned feeding mouth 12, and then via jet 11 ejections, and be sprayed on the workpiece.

With further reference to Fig. 2 and shown in Figure 3, for the utility model in order to the spraying fluid in an enforcement schematic diagram that is formed at the spiro tooth part 20 on the round bar, wherein, the footpath that body 10 is positioned at spiro tooth part 20 makes progress, and jet 11 is toward spiro tooth part 20, advantage of the present utility model is, owing to cooperating spiro tooth part 20, the end face of its jet 11 is banded cambered surface, jet 11 end face integral body can be close to the surface of spiro tooth part 20, therefore each endface position equates to the distance of spiro tooth part 20 is rough on the jet 11, after fluid is by jet 11 ejections, fluid can be evenly distributed on the spraying position of spiro tooth part 20, make coating layer thickness comparatively even, can improve the shortcoming that the nozzle spraying is inhomogeneous or the control of spraying processing procedure is difficult for of prior art.

Claims (2)

1. a nozzle arrangements includes a body, it is characterized in that:

This body is a hollow, and is formed with a feeding mouth and a jet respectively in two ends, and is formed with an end of jet, and wherein two relative walls and contract in opening part and be an arcuation make the end face of this jet be a banded cambered surface.

2. nozzle arrangements as claimed in claim 1 is characterized in that: this feeding mouth is rounded.
