Description

Technical Field

[0001] The utility model relates to an economical casting fixing frame, which is used for fixing and connecting double guide rods and a pool wall in a coupling device of a submersible sewage pump. Background Art

[0002] The existing conventional fixing plate is a welded structure, see Figure 1 and Figure 2 , Figure 1 The flat steel 11 (fixed plate), 12 waist hole, 13 flat steel (guide rod seat plate), 14 flat steel (reinforcement rib), a said flat steel 11 is long strip, the welding part is long, to ensure no deformation during welding, the thickness is 10mm; b said flat steel 11 is laser cut with 2 symmetrical waist holes; c flat steel 13 is shaped like Figure 1 and Figure 2 , one end is welded to the flat steel 11; d. The shape of the flat steel 14 is as follows Figure 1 and Figure 2 , the two right angle sides are welded to the flat steel 11 and the flat steel 13 respectively; e After the flat steel is welded, a through hole is drilled on the inner side of the flat steel 13; f Finally, the weld is polished; if necessary, the flat steel 11 is partially shaped and leveled due to welding deformation; This fixed frame consumes materials, has many processes, and is troublesome to transfer. It is urgent to design a simple structure to shorten the processing cycle. Figure 3 It is an existing conventional fixed plate installation structure. Figure 3 Middle: 21 fixing plate, 22 guide rod, 23 nut, 24 bolt, 25 upper fixing pad, 26 spring washer, 27 rubber plug, 28 lower fixing pad. During installation, there is no guide rod seat, so the fixing pad and rubber plug are placed in sequence below the positioning hole of the fixing plate; the upper fixing pad is placed above the positioning hole of the fixing plate; the bolt is inserted from the lower fixing pad, and passes through the lower fixing pad, rubber plug, positioning hole of the fixing plate, upper fixing pad, and spring washer in sequence, screw in the bolt and tighten it slightly, move the fixing frame against the upper part of the guide rod, insert the outer circle of the rubber plug into the hollow part of the guide rod, tighten the nut, so that the rubber plug is deformed and fills the inner wall of the guide rod. Summary of the invention

[0003] The utility model aims at the above-mentioned problems existing in the prior art and provides an economical casting fixing frame. The utility model designs an economical casting fixing frame, including a fixing plate, characterized in that waist-shaped holes for installation are provided at both ends of the fixing plate, a protruding guide rod seat plate is provided in the middle of the fixing plate, and a guide rod seat is provided on the guide rod seat plate. A reinforcing rib is provided on the fixing plate, and the bottom edge of the reinforcing rib is connected to one side of the guide rod seat plate. The guide rod seat plate, the fixing plate and the reinforcing rib are cast as one body. The guide rod seat is a conical table cylinder. The advantage of the utility model is that it adopts an integral casting fixing frame. A casting guide rod seat is provided on the fixing frame. The guide rod seat is a conical table. When the fixing frame is inverted, a circle of the conical table of the guide rod seat is in line contact with the inner wall of the guide rod. The casting fixing frame has fewer processes, and at the same time reduces the upper and lower fixing pads, bolts, nuts, spring washers and other fasteners, rubber plug parts. The new structural design achieves the purpose of reducing costs and increasing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following describes the specific implementation of the utility model in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the utility model. Although the utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, rather than limiting the scope of the utility model.

[0012] The figure shows an economical casting fixing frame, comprising a fixing plate 1, characterized in that there are waist-shaped holes 2 for mounting at both ends of the fixing plate, a protruding guide rod seat plate 3 is provided in the middle of the fixing plate, and a guide rod seat 4 is provided on the guide rod seat plate. A reinforcing rib 5 is provided on the fixing plate, and the bottom edge of the reinforcing rib is connected to one side of the guide rod seat plate. The guide rod seat plate, the fixing plate and the reinforcing rib are cast as one body. The guide rod seat is a conical cylindrical column.

[0013] The entire fixing frame is cast in one step. Since welding and machining are not required, manpower and material resources can be saved. When installing, the fixing frame is reversed, and its guide rod seat is in contact with the guide rod 6; the waist hole passes through the expansion bolt screw, and the nut is tightened to complete the installation. Compared with the installation of the existing technology, the casting type fixing frame has fewer processes, and at the same time reduces the upper and lower fixing pads, bolts, nuts, spring washers and other fasteners, rubber plug parts. The new structural design achieves the purpose of reducing costs and increasing efficiency.
