Embodiment Construction

[0029] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the following embodiments will specifically describe an automatic push-pull bolt device of the present invention in conjunction with the accompanying drawings. It should be noted that for these embodiments The description is used to help understand the present invention, but does not constitute a limitation to the present invention.

[0030] Such as figure 1 and figure 2 As shown, the 7.62mm caliber gun type firearm in this embodiment has a barrel A, a gun stock B, a bolt C, and a trigger D.

[0031] The barrel A is straight and has a muzzle at the end for firing bullets. The butt B is perpendicular to the barrel A. The bolt C can move along the length of the barrel A and relative to the barrel A. The bolt C has a predetermined locking position and a predetermined unlocking position on the moving path of the barrel A. The predetermined lock...

Abstract

The invention belongs to the field of equipment testing, and discloses an automatic bolt column pushing and pulling device which comprises a base, a pushing and pulling assembly and a bolt column rotating assembly. The base is provided with a moving guide rail. The pushing and pulling assembly comprises a pushing and pulling base plate and a pushing and pulling electric push rod, the pushing and pulling base plate is arranged on the moving guide rail in a matched mode, and a protruding part protrudes out of the pushing and pulling base plate. The output end of the pushing and pulling electric push rod is installed on the protruding part. The bolt column rotating assembly comprises a rotating motor, a first connecting crank and a bolt column linkage rod, the free end of the bolt column is installed at the output end of the rotating motor through the first connecting crank and the bolt column linkage rod which are connected with each other, the pushing and pulling assembly can drive a bolt column to move, the bolt column rotating assembly can drive the bolt column to rotate, so that the automatic bolt column pushing and pulling device can automatically push and pull the bolt column of the a firearm without on-site participation of personnel, the automation degree of the bolt column pushing and pulling operation of the firearm is greatly improved, and the personal health and safety of related personnel are guaranteed.

Description

technical field [0001] The invention belongs to the field of equipment testing, and in particular relates to an automatic push-pull bolt device. Background technique [0002] As a special equipment, firearms require strong reliability and strong environmental adaptability in the actual use process, and they are required to still perform their functions in special environments. In view of this point, firearms must be tested in the environment before they are put into use. Test and reliability test, and the action of pushing and pulling the bolt to the firearm is indispensable in the above-mentioned test. [0003] The 7.62mm caliber test gun has a straight barrel and a stock with a vertical barrel. There is a bolt on the barrel (bolt, the same below). The bolt can move along the barrel and relative to the barrel. There are locked position and unlocked position on the moving path of the barrel. In the locked position, the bolt can be fixedly set by rotating and locking. The bo...
