Abstract

The utility model mainly relates to a dust collection and chip removal device, in particular to a vacuum generator, which comprises a spray nozzle, a chip feeding tube, and a plastic tube, wherein, the plastic tube and one end of the chip feeding tube are fixedly connected and communicated with each other, and the other end of the chip feeding tube is connected with the spray nozzle through a three-way pipe body. The dust collection and chip removal device has the advantages of simple structure, compact mechanism, and convenient adjustment.

Description

Vacuum generator

Technical field:

The utility model relates generally to a kind of dust suction chip removal device.

Background technology:

Dust exhaust apparatus on the existing lathe mostly is independently dust suction pump.Volume is huge relatively, the cost height, and power consumption is big.Lathe drops around workpiece at random at the chips such as iron filings aluminium bits that add the generation in man-hour, and the chip location in space is limited by workpiece, anchor clamps, cutter etc., brings difficulty to chip removal.Traditional dust suction pump is limited by own vol, and is the industrialized standard product, and the processing situation for specific needs is difficult to satisfy the chip removal needs.When the real-time chip removal of processing request, perhaps during the deep hole processing blind hole, small volume and less weight chip removal device efficiently seems very necessary.

Summary of the invention:

The purpose of this utility model is to solve the deficiencies in the prior art and a kind of vacuum generator is provided, and it is simple in structure, and mechanism's compactness is easy to adjust.

The purpose of this utility model can be by realizing by the following technical solutions: a kind of vacuum generator, include nozzle, advance the bits pipe, plastic tube, described plastic tube is connected with an end that advances to consider to be worth doing pipe and interconnects, and the other end that advances to consider to be worth doing pipe is connected with nozzle by the threeway body.The plastic tube other end extends to the zone that needs chip removal.

Further, be provided with bolt on described threeway body, the threeway body is connected by bolt and support plate.

Further, the inner cone mouth of described nozzle and the corresponding configuration of the outer cone mouth that advances to consider to be worth doing pipe.

Further, the inner cone mouth of described nozzle is tapered with the outer cone mouth that advances to consider to be worth doing pipe, and the corresponding configuration of big footpath opening of advancing to consider to be worth doing outer cone prostomum shape path opening with the inner cone mouth of nozzle of pipe.

Further, the inner cone mouth of described nozzle and advance to consider to be worth doing between the outer cone mouth of pipe and be provided with fluid cavity is connected the cooperation place at inner cone mouth and outer cone mouth and is provided with fluid gap, is provided with fluid inlet channel above fluid gap.When fluid passes through fluid gap by fluid intake, the area of section of flowing through suddenly diminishes, fluid is forced to quicken to flow, swiftly flowing fluid longshore current body space can form circular arc camber, the fluid cavity internal pressure is reduced, under the atmospheric pressure effect, dust, chips etc. are from advancing bits mouthful suction vacuum generator.

Further, described plastic tube with advance to consider to be worth doing pipe and be connected by the larynx hoop.

Further, described advance to consider to be worth doing pipe below be provided with support plate.

Further, also be provided with locking nut on described nozzle, locking nut is connected with the threeway body by bolt.The depth-adjustment of nozzle in the threeway body locked by locking nut.

The beneficial effects of the utility model are: it is simple in structure, and mechanism's compactness is easy to adjust.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an A part-structure schematic diagram among the figure one of the present utility model.

The specific embodiment:

Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing:

Embodiment 1, sees Fig. 1, Fig. 2, and a kind of vacuum generator includes nozzle 1, advances bits pipe 2, plastic tube 3, described plastic tube 3 is connected with an end that advances bits pipe 2 and interconnects, and the other end that advances bits pipe 2 is connected with nozzle 1 by threeway body 4.Plastic tube 3 other ends extend to the zone that needs chip removal.Be provided with bolt on described threeway body 4, the threeway body is connected by bolt and support plate 9.The inner cone mouth of described nozzle 1 and the corresponding configuration of outer cone mouth of advancing bits pipe 2.The inner cone mouth of described nozzle 1 is tapered with the outer cone mouth that advances bits pipe 2, and advances the corresponding configuration of big footpath opening of outer cone prostomum shape path opening with the inner cone mouth of nozzle 1 of bits pipe 2.The inner cone mouth of described nozzle 1 and advance between the outer cone mouth of bits pipe 2 to be provided with fluid cavity 5 is connected the cooperation place at inner cone mouth and outer cone mouth and is provided with fluid gap 6, is provided with fluid inlet channel 7 above fluid gap 6.When fluid passes through fluid inlet channel 7 through fluid gaps 6, the area of section of flowing through suddenly diminishes, fluid is forced to quicken to flow, swiftly flowing fluid longshore current body space can form circular arc camber, the fluid cavity internal pressure is reduced, under the atmospheric pressure effect, dust, chips etc. are from advancing bits mouthful suction vacuum generator.Described plastic tube 3 with advance bits pipe 2 and be connected by the larynx hoop.Described advance bits pipe 2 below be provided with support plate 9.Also be provided with locking nut 8 on described nozzle 1, locking nut 8 is connected with threeway body 4 by bolt.The depth-adjustment of nozzle 1 in threeway body 4 is by locking nut 8 lockings.

During work, air stream or liquid stream enter from inlet, when fluid process fluid gap, the area of section of flowing through suddenly diminishes, and fluid is forced to quicken to flow, swiftly flowing fluid can form circular arc camber along taper hole, cause B inside cavity pressure to reduce, under the atmospheric pressure effect, dust, chips etc. finally spray from nozzle with fluid from advancing bits mouthful suction vacuum generator.Unclamp the bolt on the locking nut 8, swivel nozzle, the size that can regulate fluid gap is regulated dust removal ability thus.
