Abstract
The utility model relates to a two-point press machine crankshaft connection structure in the technical field of press machines. The two-point press machine crankshaft connection structure comprises a left crankshaft and a right crankshaft, wherein the left crankshaft and the right crankshaft are symmetric in a left-and-right mode. The right shaft end of the left crankshaft is connected with the left shaft end of the right crankshaft through a coupler. A plurality of concentric positioning pin holes are further correspondingly formed in the end portions where the left crankshaft is connected with the right crankshaft. Positioning pins are installed inside the corresponding positioning pin holes in an equipped mode. The positioning pin holes are arranged in a split mode in the circumferential face where the connection ends of the left crankshaft and the right crankshaft are circumferentially matched with the coupler. The two-point press machine crankshaft connection structure has the advantages of being capable of well ensuring the concentric accuracy of the combined-type segmented two-point crankshafts, and convenient to install and overhaul.
Description
Technical field
The utility model relates to the press technologies field, particularly a kind of two-point press bent axle syndeton.
Background technology
The market demand of the high-speed blanking press of the big work top of large-tonnage is increasing at present, lathe will be designed to big work top, just need be designed to two point and forcing press at 4, and the spacing of two point off-centre increases, and designed like this structure mainly contains two kinds: the two eccentric traverses of single bent axle and hyperbolic axle are indulged and are put.Though the hyperbolic axle can be realized the requirement of the eccentric big spacing of two point, and inapplicable high-speed blanking press, because the synchronism error can show more obviously under running up.Therefore the high speed two-point press is usually designed to the two eccentric traverse structures of single bent axle, but the forcing press for big workbench, the spacing that increases two off-centre will make the very long of crankshaft designs, bring certain degree of difficulty so just for processing and manufacturing and installation maintenance, for overcoming this difficulty, have to and to be designed to two segments combined structure than long two eccentric crankshafts, this structure generally adopts rigidity shaft coupling system and swelling cover to connect, but find in practice, use rigidity shaft coupling system and swelling cover and have also certain synchronism error, and be not easy to install and maintenance.
The utility model content
The problem that the utility model is deposited at prior art provides a kind of easy accessibility, synchronism good, is particularly suitable for the two-point press bent axle syndeton of big work top.
The purpose of this utility model is to realize like this, a kind of two-point press bent axle syndeton, comprise symmetrical left bent axle and right bent axle, the right axle head of described left bent axle is connected by shaft coupling with right bent axle left side axle head, the end that described left bent axle is connected with right bent axle is also corresponding to be provided with some concentric dowel holes, is fitted with alignment pin in the dowel hole of described correspondence.
Be further to guarantee the synchronism of bent axle, on the link that described dowel hole dissection type is arranged at left bent axle and right bent axle and the periphery that shaft coupling circumferentially cooperates.
For bent axle is connected firmly, described dowel hole and the alignment pin that is connected evenly are provided with six groups at the link of left bent axle and right bent axle.
Bent axle syndeton of the present utility model, during the processing locating hole, at first left bent axle and right bent axle are mixed up eccentric phase angle with testing tool, guarantee the concentricity precision of two off-centre, be the accurate concentricity precision that guarantees, utilize frock to be fixed on the corresponding dowel hole of pairing processing simultaneously on the bent axle on shaft coupling.During installation, adjust the eccentric phase place of bent axle earlier with testing tool, identical to guarantee two eccentric precision, then alignment pin is fitted in the corresponding dowel hole and fixes with shaft coupling at last.When the maintenance bent axle, only shaft coupling need be unclamped and get final product.Therefore the beneficial effects of the utility model are: can well guarantee the concentricity precision of combined type segmentation two point bent axle, and be convenient to install and maintenance.
Description of drawings
Fig. 1 is two-point press bent axle syndeton schematic diagram of the present utility model.
Fig. 2 is that Fig. 1 is at the cutaway view at A-A place.
Wherein, 1 left bent axle; 2 right bent axles; 3 alignment pins; 4 shaft couplings.
The specific embodiment
Be two-point press bent axle syndeton of the present utility model as depicted in figs. 1 and 2, comprise symmetrical left bent axle 1 and right bent axle 2, left side bent axle 1 right axle head is connected by shaft coupling 4 with right bent axle 2 left axle heads, the end that left side bent axle 1 is connected with right bent axle 2 also correspondence is provided with some concentric dowel holes, is fitted with alignment pin in the corresponding dowel hole; Be further to guarantee the synchronism of bent axle, on the link that the dowel hole dissection type is arranged at left bent axle 1 and right bent axle 2 and the shaft coupling 4 circumferential peripheries that cooperate; For bent axle is connected firmly, dowel hole and the alignment pin 3 that is connected evenly are provided with six groups at the link of left bent axle 1 and right bent axle 2.
Bent axle syndeton of the present utility model, during the processing locating hole, at first left bent axle 1 and right bent axle 2 usefulness testing tools are mixed up eccentric phase angle, guarantee the concentricity precision of two off-centre, be the accurate concentricity precision that guarantees, utilize frock to be fixed on the bent axle link on shaft coupling 4 and match the corresponding dowel hole of processing simultaneously.During installation, adjust the eccentric phase place of bent axle earlier with testing tool, identical to guarantee two crankshaft eccentric precision, then alignment pin 3 is fitted in the corresponding dowel hole last fixing with shaft coupling 4.When the maintenance bent axle, only shaft coupling 4 need be unclamped and get final product.Therefore the beneficial effects of the utility model are: can well guarantee the concentricity precision of combined type segmentation two point bent axle, and be convenient to install and maintenance.
The utility model is not limited to above-described embodiment; every on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in the scope of the utility model protection.
