Example Embodiment

[0039] Example 1

[0040] This embodiment discloses a method for assembling a combined casing, refer to the appendix of the specification. Figure 1-Figure 13 As shown, the assembling method specifically includes the following steps:

[0041] Step 1. First, place the left side plate 9 of the receiver and the right side plate 5 of the receiver on both sides of the first positioning block 16. Put the upper cover 1 on the top of the left side plate 9 of the casing and the right side plate 5 of the casing in turn, and cover the top cover 1 on the left side plate 9 of the casing and the right side plate 5 of the casing. The lower part of the casing 11 is covered with the lower part of the plate 5, so that the left side plate 9 of the casing, the right side plate 5 of the casing, the upper casing 1 and the lower casing 11 of the casing form a whole assembly, and then cover the upper part of the assembly respectively. Insert the two positioning clamping clamps 15, tighten the clamp...

Example Embodiment

[0052] Example 2

[0053] This embodiment discloses a method for assembling a combined casing, refer to the appendix of the specification. Figure 1-Figure 13 As shown, on the basis of Embodiment 1, the upper cover 1 of the receiver, the lower seat 11 of the receiver, the left side plate 5 of the receiver, the right side plate 9 of the receiver, the buffer seat 2 and the lever seat 7 are all provided with preset Leave holes. When the casing is assembled and processed, it is only necessary to drill the reserved holes of each component to the diameter of the rivet, so that the rivet can pass smoothly, but the displacement between each component is very small.

[0054] Further, a card slot is arranged on the inner side of the upper cover 1 of the casing, and a boss adapted to the card slot is arranged on the buffer seat 2, and the boss is axially fixed in the card slot.

[0055] Further, when assembling in the eighth step, the second positioning block 26 is put into the assembl...

Abstract

The invention relates to the technical field of firearm assembly, and discloses an assembly method of a combined cartridge receiver. The assembly quality of the cartridge receiver and the performanceof a formed product are ensured by improving the assembly method of the combined cartridge receiver, and finally the precision and reliability of firearm shooting are improved.

Description

technical field [0001] The present application relates to the technical field of firearm assembly, in particular to an assembly method of a combined receiver. Background technique [0002] The receiver is the basic component of an automatic weapon, and its main function is to combine all other parts and components together to form a whole. Guide the movement of the mobile body during work, and cooperate with relevant agencies to complete actions such as unlocking, locking, bomb feeding, and shell ejection. Therefore, the quality of the receiver will directly affect the reliability of automatic weapons. The advantage of the punching riveting process is that it can simplify the processing of parts, is suitable for mass production, and can effectively reduce production and material costs. However, due to the complex structure of the casing, the large size and high requirements for mutual position accuracy, the manufacturing process of the casing is complicated, and it is diff...
