Fig. 1: the structural representation of the utility model embodiment.

The specific embodiment

Make a detailed explanation below in conjunction with 1 pair of specific embodiment of the present utility model of accompanying drawing.

Impeller roll riveting device on a kind of metal blast fan make-up machine is as shown in Figure 1 mainly separated 72 mechanisms, roll riveting motor and hydraulic system and is constituted by roll riveting base plate 71, roll riveting frame 75, last roll riveting mechanism 74, following roll riveting mechanism 73, bottom roller.

Last roll riveting mechanism 74 is installed on the roll riveting frame 75, and the guide pillar 751 on the roll riveting frame 75 is vertically fixed on the roll riveting base plate 71.Last roll riveting mechanism 74 by upper mounted plate 741, upper slide 742, go up rolling wheel 743, upper roller frame 744 and roll riveting oil cylinder 745 and constitute.Upper mounted plate 741 and upper slide 742 are installed on the guide pillar 751 of roll riveting frame 75, last rolling wheel 743 is installed on the upper slide 742 by upper roller frame 744, roll riveting oil cylinder 745 is installed on the upper mounted plate 741, roll riveting oil cylinder 745 outputs connect goes up rolling wheel 743, rolling wheel 743 can be done the oscilaltion campaign under roll riveting oil cylinder 745 acts on, and impeller is carried out roll riveting.Upper slide 742 the position on the guide pillar 751 adjust up and down rolling wheel 743 in the realization and following roll riveting mechanism 73 between the adjustment of height, impeller that promptly can the roll riveting different-diameter.

Following roll riveting mechanism 73 is mainly by side plate 731 is installed in roll riveting down, a plurality of rolling wheel 732, position-limited rack 733 and gear trains 734 down constitute.Following roll riveting is installed side plate 731 and is fixed on the roll riveting base plate 71, a plurality of rolling wheel 732, position-limited rack 733 and gear trains 734 down are installed in roll riveting and install on the side plate 731, following rolling wheel 732 links to each other with gear train 734, and the position of position-limited rack 733 is in the top of rolling wheel 732 down.Each is equipped with the impeller stopper slot 7321 that many groups are parallel to each other on the rolling wheel 732 down, and the left side plate of position-limited rack 733 aligns with the left and right end portions of following rolling wheel 732.During roll riveting, the mid-game on the impeller is stuck in the impeller stopper slot 7321, has guaranteed can laterally not moving or beat of impeller, and impeller can be evenly stressed during roll riveting, the impeller quality height that roll riveting forms.

Bottom roller separating mechanism 72 mainly is made of separation cylinder 721, limited block 722, slide block 723 and connecting plate 724.Outermost rolling wheel 732 down is installed on the slide block 723, and slide block 723 is fixedlyed connected with connecting plate 724.The output of separation cylinder 721 links to each other with connecting plate 724, the outermost rolling wheel 732 down of separation cylinder 721 controls moves, limited block 722 is installed in the outer end that side plate 731 is installed in roll riveting, and its purposes is to prevent that separation cylinder 721 from pulling out outermost time rolling wheel 732 transition.Outermost down rolling wheel 732 separated cylinders 721 will be pulled out back itself and adjacent following rolling wheel 732 and the gap just occurred, the impeller that roll riveting is finished just falls from gap location, bottom roller separating mechanism 72 has made things convenient for the taking-up of impeller after the roll riveting, for producing the condition of having created continuously.

Above-mentioned down rolling wheel 732 is two, and one is installed on roll riveting and installs on the side plate 731 and link to each other with gear train 734, and gear train 734 links to each other with the roll riveting motor, the rotation torque when the impeller roll riveting is provided.Another and slide block 723 assemble, and slide block 723 is along with the output of separation cylinder 721 is made back and forth movement, and after roll riveting was finished, separation cylinder 721 work broke away from the transmission idle wheel on following rolling wheel 732 and the gear train 734, and two following rolling wheels 732 separate.

Hydraulic oil pipe on the hydraulic system links to each other with roll riveting oil cylinder 745, the roll riveting motor be connected gear train 734 by the rolling riveter belt pulley.

During use, impeller rolls into down on the rolling wheel 732, following rolling wheel 732 high speed rotating, and last rolling wheel 743 is descending to carry out roll riveting to impeller and fixes.Go up rolling wheel 743 after roll riveting is finished and return, the outermost rolling wheel 732 down on the slide block 723 is pulled out in separation cylinder 721 actions, and the impeller after the moulding falls into from gap location and falls.

Above-mentioned enforcement only is this patent embodiment preferably, for example goes up the structure that roll riveting oil cylinder 745 in the roll riveting structure 74 also can adopt cylinder.The protection domain that all belongs to this patent is modified in the structure that all employing the technical program are described, feature and the variation on its spiritual principle.
