Problems solved by technology

The difficulties in the existing automatic assembly technology for small-caliber bullets are: 1. The accurate positioning of the primer and the shell case is to ensure the coaxiality of the two to facilitate accurate press-fitting; 2. Based on the requirements of the primer-pressing process itself, it is necessary to ensure The exact force application position of the rod to the cartridge case, and the exact force application position of the ejector rod to the primer

Embodiment Construction

[0022] Such as figure 1 As shown, this embodiment relates to a small-caliber ammunition primer press-fitting mechanism with the self-centering function of the push-pull gear, including: several primer press-fit units arranged side by side and meshing with each other and a drive connected to one primer press-fit unit mechanism, wherein: the primer pressing unit is rotatably arranged on the fixed base plate, and the reciprocating motion of the driving mechanism drives each primer pressing unit to rotate.

[0023] The primer pressing unit includes: a pressure rod 5 and a push rod 8 arranged oppositely up and down, an assembly flange 10 and a pusher gear 9 arranged outside the push rod 8 in turn, wherein: one end of the cartridge case 6 is sleeved on the pressure rod 5 end, the other end is set in the assembly flange 10, and the primer 7 is set on the top of the push rod 8.

[0024] Such as figure 2 As shown, the bottom of the pressing rod 5 is provided with a taper 52 and a s...

Abstract

A self-centering small-caliber ammunition primer press-fitting mechanism with a push-pull gear mechanism comprises a plurality of primer press-fitting units and a driving mechanism, the primer press-fitting units are arranged in parallel and meshed with one another, and the driving mechanism is connected with one primer press-fitting unit, wherein the primer press-fitting units are rotationally arranged on a fixed base plate, and the driving mechanism reciprocates to drive each primer press-fitting unit to rotate. According to the mechanism, accurate coaxial positioning of a primer and a cartridge case in the automatic bullet assembling process can be achieved, and the accurate force application position of a pressing rod to the cartridge case and the accurate force application position of an ejector rod to the primer are limited at the same time. The self-centering small-caliber ammunition primer press-fitting mechanism is simple and reliable in structure, high in efficiency and high in practicability. The stability of a small-caliber ammunition assembly system and the press-fitting precision of the primer are greatly improved.

Description

technical field [0001] The invention relates to a technology in the field of small-caliber ammunition assembly, in particular to a self-centering small-caliber ammunition primer press assembly mechanism with a push-pull gear mechanism. Background technique [0002] Small-caliber ammunition is the basic combat readiness of national defense. In the assembly process of small-caliber bullets, how to improve assembly efficiency and meet the needs of large-scale production is one of the technical problems that need to be solved in this field. The difficulties in the existing automatic assembly technology for small-caliber bullets are: 1. The accurate positioning of the primer and the shell case is to ensure the coaxiality of the two to facilitate accurate press-fitting; 2. Based on the requirements of the primer-pressing process itself, it is necessary to ensure The exact force application position of the rod to the cartridge case, and the accurate force application position of th...
