Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to a clamping and positioning device for tooling for loading and unloading movement components. Background Technology

[0002] The barrel is a crucial core component of the rifle. After being press-fitted with the sleeve, it forms a locking mechanism that secures the automatic mechanism to the barrel and the chamber. When the chamber is under the pressure of propellant gases, it prevents the automatic mechanism from moving backward for a certain period, ensuring that the propellant gases fully propel the bullet and prevent leakage that could cause an accident. Before pressing the barrel and sleeve together, the outer circumference of the barrel needs to be... Figure 1 The machining process involves machining the cartridge case. Because the diameter of the chamber end and the tail end of the cartridge case are not the same, and the chrome plating inside the chamber is prone to peeling off during clamping, direct clamping and positioning with double centers is not possible during the outer diameter machining. A mechanism fixture is required. Figure 2 Installed into the chamber ( Figure 1 Inside, the chamber end clamping surface is moved to the mechanism tooling clamping surface, and then the outer diameter is machined. After the outer diameter of the barrel is machined and before it is pressed into the sleeve, the extractor hook clearance groove on the barrel end face needs to be made. Figure 1 Positioning is performed to ensure that the locking mechanism formed after press-fitting allows the extractor to smoothly enter the barrel end face, driving the cartridge case backward to achieve the ejection function of the firearm. Currently, the installation and removal of the mechanism tooling and the positioning of the extractor clearance groove during barrel outer diameter machining are all done manually. This is labor-intensive and not suitable for upgrading the press-fitting of the locking structure to automation. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a clamping and positioning device for the tooling of loading and unloading the movement of the barrel. When loading and unloading the movement of the barrel, the barrel can be clamped and positioned by this utility model.

[0004] The purpose of this utility model is achieved as follows: A clamping and positioning device for mounting and dismounting movement components includes a worktable, a front clamping cylinder base plate, and a rear clamping and positioning base plate. A worktable guide rail is provided on the worktable, and the front clamping cylinder base plate and the rear clamping and positioning base plate are fitted onto the worktable guide rail. The tail end clamping and positioning base plate is equipped with a tail end positioning V-block and a tail end clamping cylinder. The tail end clamping cylinder is poweredly connected to a tail end clamping V-block through a rear end clamping connecting block. The tail end positioning V-block is used to support the body tube, and the tail end clamping cylinder is used to drive the tail end clamping V-block to clamp the body tube. The front clamping cylinder base plate is equipped with a front positioning V-block and a front clamping cylinder. The front clamping cylinder is poweredly connected to a front clamping arc-shaped pressure block and a front end face stop block through a front clamping connecting block. The front positioning V-block is used to support the body tube, the front clamping cylinder is used to drive the front clamping arc-shaped pressure block to press the body tube, and the front end face stop block is used to limit the end face of the body tube. The front end face stop block is provided with a clearance groove, which is used to allow clearance for the shaft part of the movement tooling.

[0005] When installing or removing the movement tooling in the barrel, this utility model can be used to clamp and position the barrel, exposing the chamber position, and then the movement tooling can be inserted and removed.
