Abstract
The invention discloses a metal mounting seat novel structure weight reduction design method used for a cartridge receiver. The method comprises a mounting hole center circle diameter, a rivet hole center circle diameter, a mounting seat weight reduction external diameter, a mounting seat external contour diameter, a mounting hole external diameter, three inverted circular beads, an internal contour diameter, two weight reduction hole diameters, a mounting threaded hole height, a mounting seat height, a mounting seat riveting thickness, a chamfer, two inverted circular beads, an internal threaded hole diameter, a rivet hole diameter and two positioning angles. The mounting hole center circle diameter, the rivet hole center circle diameter, the mounting seat weight reduction external diameter, the inverted circular beads and the weight reduction hole diameters are subjected to weight reduction layout design. The metal mounting seat novel structure weight reduction design method has the advantages that a three-dimensional structure parametric modeling method controlled by an expression and a law curve can be applied to quickly revise different mounting seat layouts, the quick design of a remodeled product can be carried out, and the method is suitable for designing a composite material cartridge receiver metal mounting seat.

Installing hole center circle diameter (1), rivet hole center circle diameter (2), mounting seat loss of weight overall diameter (3), rounding (6), lightening hole diameter (10), lightening hole diameter (11) are carried out loss of weight layout designs；
Utilize loss of weight design rule, carry out the structural arrangementoptimization of the installing hole center circle diameter (1) of metal installation base, rivet hole center circle diameter (2), mounting seat loss of weight overall diameter (3), mounting seat gabarit diameter (4), rounding (6), interior wide diameter (9), lightening hole diameter (10), lightening hole diameter (11), orientation angle (20), orientation angle (21)；Loss of weight design rule is utilized to carry out the structural design of rounding (7), rounding (8).
The described metal installation base new structure weight reduction design method for casing, classifies according to interior wide diameter (9) Db size, and the rule between mounting seat setting structure size is in Table 1；
In the design process, design input variable is for installing bore center circle diameter gabarit diameter (1) Da or interior wide diameter (9) Db, and the setting rule formula that both can be passed through in table 1 calculates conversion；
Within the classification of wide diameter (9) Db size distinguish 2 kinds of mounting seat Lightened structure design form: 40～60mm (structure a) and 60～90mm (structure b)；
Table 1 composite casing mounting seat loss of weight design rule
What in utilization, in table, design rule designed is the design structure of mounting seat.
Advantages of the present invention:
Metal installation base new structure weight reduction design method for casing of the present invention, use the three dimensional structure parametric modeling method that expression formula and law curve control, can quickly revise different mounting seat layout, and the quick design of remodeling product can be carried out, it is adaptable to composite casing metal installation base designs.
