the single-chip diagram of the frame is described by a table number: a first middle wall plate, a second triangular plate, a third guide sliding plate and a sixth connecting plate.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
The assembling tool for the large-scale low-speed marine diesel engine rack single piece is characterized in that a bottom plate 1 and a bottom plate 7 are welded between planes of two rib plates (2) which are erected side by side, clamping grooves are continuously arranged on the upper portions of the rib plates, corresponding positioning plates 5 are vertically and correspondingly installed on the clamping grooves, grooves corresponding to specification positioning are formed in the positioning plate parts between the rib plates, upright distance plates 3 are welded on vertical surfaces of the positioning plates near the grooves, screw holes in the horizontal direction are formed in the distance plates, adjusting falling screw rods are matched with the screw holes, and baffle plates 6 are installed at the tops of the bottom plate 7 and the rib plates 2 to play a role in positioning. The rib plate 4 is arranged at the included angle between the rib plate 2 and the positioning plate 5 to play a role in reinforcement. Five positioning plates 5 are arranged on a ribbed plate 2, and a supporting plate 8 penetrates through and is fixed at the lower parts of the five positioning plates to be grooved and is supported below a bottom plate 1, and a distance plate 3, a ribbed plate 4 and a baffle 6 are also supported.
The position of the rack single-sheet guide sliding plate (III) is fixed through a groove of a positioning plate 5 corresponding to the specification, the left-right distance is adjusted by a screw on the distance plate 3 and is accurately positioned, the front end of the rack single-sheet guide sliding plate (III) is positioned by a baffle 6, and the height distance of the rack single-sheet guide sliding plate (III) is positioned on the bottom plate 1, as shown in figure 3.
