Embodiment 1

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

[0041] Step 1. First, place the left side plate 9 and the right side plate 5 of the receiver on both sides of the first positioning block 16, and engage the gun tail slots on the left side plate 9 and the right side plate 5 of the receiver respectively. Insert it into the positioning boss of the first positioning block 16, and then cover the casing upper cover 1 on the top of the left side plate 9 and the right side plate 5 of the casing in turn, and cover the left side plate 9 and the right side of the casing The lower part of the plate 5 is covered with the casing lower seat 11, so that the casing left side plate 9, the casing right side plate 5, the casing upper cover 1 and the casing lower seat 11 form a whole assembly, and then respectively cover the casing on the top of the assembly. Insert two positio...

Embodiment 2

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

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

[0055] Further, when the step eight is assembled, the second positioning block 26 is put into the assembly from the rear of the assembly, and the positioning groove on the second positioning block is just ali...

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...
