Description

Technical Field

[0001] The invention relates to the technical field of sighting mirror processing, in particular to a lens barrel drilling processing device. Background Art

[0002] The origin of the scope, or optical aiming device, is difficult to verify. It is said that at least in Europe in the 16th century, people had tried to fix eyeglass lenses on the buttstock. The scope is mainly divided into the following three categories: telescopic sight, collimating sight and reflex sight. Among them, telescopic sight and reflex sight are the most popular. When processing the main barrel of the scope, it is necessary to drill a hole in the main barrel to facilitate the installation of the adjustment handwheel for adjusting the aiming accuracy.

[0003] There are many problems in the prior art when drilling holes in the scope barrel: Since the scope is usually made of harder metal, when drilling, the drill bit will heat up due to hard friction after each hole is drilled. If drilling is continued, it is easy to cause serious wear of the drill bit and reduce its service life. The sizes of the barrel mirrors at both ends of the scope are different, and both ends need to be positioned separately before drilling. Positioning requires manual locking of both ends. It is difficult to ensure that the barrel can remain level after positioning, which will cause tilting when drilling. Summary of the invention

The gas will be first delivered to the fixed ring 71 on the left, and then delivered to the fixed ring 71 on the right. As the gas is filled, the third piston 73 slides in the fixed ring 71 and squeezes the third spring 74, and balances the air pressure on both sides of the third piston 73 through the air hole when the third piston 73 slides. The third piston 73 drives the arc plate 77 to move, and slides in the slide groove 78 through the sliding column 79, so that the arc plate 77 drives The slide bar 75 slides toward the center of the fixing ring 71.
