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.

Example Embodiment

[0023] Example 1

[0024] This embodiment provides a new structure weight reduction design method for a metal mounting seat for a casing, which is characterized in that: the new structure weight reduction design method for a metal mounting seat for a casing includes: the center circle of the mounting hole Diameter (1), diameter of rivet hole center circle (2), mounting seat weight reduction outer diameter (3), mounting seat outer diameter (4), mounting hole outer diameter (5), fillet (6), rounding Corner (7), rounded corner (8), inner profile diameter (9), lightening hole diameter (10), lightening hole diameter (11), mounting screw hole height (12), mounting seat height (13), Mounting seat riveting thickness (14), chamfer angle (15), fillet angle (16), fillet angle (17), internal thread hole diameter (18), rivet hole diameter (19), positioning angle (20), positioning angle (21);

[0025] The diameter of the center circle of the mounting hole (1), the diameter of the center circle of the rivet hole (2), the outer diameter of the weight reduction of the mounting seat (3), the rounded corners (6), the diameter of the weight reduction hole (10), the diameter of the weight reduction hole (11 ) carry out weight reduction layout design;

[0026] Using the law of weight reduction design, the diameter of the center circle of the mounting hole of the metal mounting seat (1), the diameter of the center circle of the rivet hole (2), the outer diameter of the mounting seat for weight reduction (3), the outer diameter of the mounting seat (4), and rounding Structural layout optimization design of angle (6), inner profile diameter (9), weight-reducing hole diameter (10), weight-reducing hole diameter (11), positioning angle (20), positioning angle (21); using weight-reducing design rules Carry out the structural design of rounded corners (7) and rounded corners (8).

[0027] The new structure weight reduction design method of the metal mounting seat used for the casing is classified according to the size of the inner diameter (9) Db, and the rules between the set structural dimensions of the mounting seat are shown in Table 1;

[0028] In the design process, the design input variable is the diameter of the center circle of the mounting seat hole, the outer diameter (1) Da or the inner diameter (9) Db, both of which can be calculated and converted by the formula of the set rule in Table 1;

[0029] Two types of mounting seat weight-reducing structure design forms are distinguished by the classification of the inner diameter (9)Db size: 40-60mm (structure a) and 60-90mm (structure b);
