Description
Technical Field
The utility model relates to a shaft class spare part surface cleaning technical field, it is specific will be an annular cleaning device that blows.
Background
In the production and manufacturing process of shaft parts of a steering machine system, a plurality of oil stains, cutting fluid, scrap iron and other impurities exist on the surface of a shaft, so that a cleaning device capable of purging the surface is needed. The hole of seting up on the cylinder inner wall is taken as the mouth of blowing of current cleaning device, and the air blows out from the hole, reaches axle class surface, blows off the spot, but this kind of mode needs great compressed air just can blow off the spot, but when the air passes the aperture fast, because air vibrations can produce sharp-pointed and loud noise, nevertheless if reduce the speed of blowing, the product surface is clean again unclean.
Therefore, it is necessary to design an annular blowing cleaning device for shaft parts, which reduces noise and reduces the usage amount of compressed air on the premise of ensuring the cleanliness.
Disclosure of Invention
The utility model discloses broken through the difficult problem of prior art, designed an axle type part annular cleaning device that blows that reduces the compressed air use amount at the prerequisite of guaranteeing the cleanliness with low noise.
In order to achieve the purpose, the utility model discloses an annular cleaning device that blows, including upper cover plate, middle lamella, base, inlet channel, its characterized in that: the middle of the base is provided with a base through hole, the base through hole consists of a first coanda through hole, a second coanda through hole and a bottom hole from top to bottom, the upper surface of the base is provided with a circle of annular compressed air groove, the side surface of the base is provided with a pair of air inlet channels opposite in direction, the annular compressed air groove is communicated with the air inlet channels, an upper cover plate covers the base, the middle of the upper cover plate is provided with an upper cover through hole, the upper cover through hole consists of an upper coanda through hole and a vertical through hole from top to bottom, a middle sheet layer is arranged between the base and the upper cover plate, the middle sheet layer is annular, and the annular width of the middle sheet layer is the same as the width of the upper surface, close to the outer; the upper cover plate, the middle sheet layer and the base are fixedly connected through bolts.
The coanda sidewalls of the first coanda via have two different but constant curvatures.
The coanda sidewalls of the second coanda via have a constant curvature.
The coanda sidewalls of the upper coanda via have a constant curvature.
Compared with the prior art, utilize the cohn to reach the annular cleaning device that the effect design has the cohn and reach the lateral wall, when axle type part surface cleans, the gas that blows off among the gas blowing device drives the gaseous entering in more outside air to reduce the compressed air consumption, improve clean effect, moreover the utility model discloses change the clean hole originally into the ring channel, increase the area of circulation of air, make the area of contact on air and axle type part surface increase, reduce the air vibrations that produce when blowing simultaneously, thereby reach the purpose that improves clean dynamics, noise reduction.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1-3, the utility model provides an annular blowing cleaning device, which comprises an upper cover plate, a middle lamella, a base, an air inlet channel, wherein the center of the base 1 is provided with a base through hole, the base through hole is composed of a first coanda through hole 2, a second coanda through hole 3 and a bottom hole 4 from top to bottom, the upper surface of the base 1 is provided with a circle of annular compressed air groove 5, the side surface of the base 1 is provided with a pair of air inlet channels 6 opposite to each other, the annular compressed air groove 5 is communicated with the air inlet channels 6, the upper cover plate 7 is covered above the base 1, the center of the upper cover plate 7 is provided with an upper cover through hole, the upper cover through hole is composed of an upper coanda through hole 8 and a vertical through hole 9 from top to bottom, a middle lamella 10 is arranged between the base 1 and the upper cover plate 7, the middle lamella 10 is annular, the annular width of the middle lamella 10 is the same as the width, the middle sheet layer only covers the outer side surface of the annular compressed air groove, the upper cover plate 7, the middle sheet layer 10 and the base 1 are fixedly connected through the bolts 11, and the middle sheet layer 10 is clamped between the upper cover plate 7 and the base 1, so that a gap with the thickness of the middle sheet layer is reserved between the base 1 and the upper cover plate 7, compressed air enters the annular compressed air groove 5 from the air inlet channel 6 and flows to the shaft parts from the base through holes through the reserved gap, the size of the compressed air outlet is determined by the thickness of the middle sheet layer 10, and the amount of the blown compressed air can be effectively controlled, so that different blowing effects are achieved.
When the air current flows to axle type part, because the coanda effect, the air current can be spout along the lateral wall of base through-hole for the central point on one side of upper cover plate puts and produces a low pressure region, can refer to fig. 6, and this low pressure region then can drive around a large amount of air intercommunication high-speed spun compressed air flow and flow to that side of base together, and thus carry out lasting stable cleanness to the surface of axle type part.
Referring to fig. 4, the coanda sidewalls of the first coanda through hole 2 of the present invention have two different but constant curvatures, i.e. the angle between β 2 and β 3 is constant but not the same, and in the specific embodiment, the blowing effect is the best when β 2=70 °, β 3=45 °.
