Description

Technical Field

[0001] This application relates to the technical field of milling equipment, and specifically discloses a magazine milling tooling fixture. Background Art

[0002] A magazine is one of the essential structural components in a firearm. Generally, a magazine consists of a left wall and a right wall, which are fixed by bolts to form a cavity for placing bullets. Both the left wall and the right wall of the magazine are formed by stamping raw material plates.

[0003] After the magazine is stamped, it still needs to be milled. The milling of the magazine involves the machining of multiple surfaces. The current machining method usually involves first milling the mouth plates of the left wall and the right wall of the magazine, then cutting the head of the whole magazine by wire cutting, and finally milling the bullet holding port and the step surface. This milling method not only requires multiple milling devices, resulting in low production efficiency and high labor costs, but also requires the magazine to be clamped and fixed multiple times. Multiple clamping is likely to affect the dimensional stability of the product and reduce the product quality. Therefore, in view of this, the inventor provides a magazine milling tooling fixture to solve the above problems. Utility Model Content

[0004] The purpose of the present utility model is to solve the problems in traditional magazine milling, such as the need for multiple clamping and multiple milling devices, high labor costs, and poor dimensional stability of the product.

[0005] To achieve the above purpose, the basic scheme of the present utility model provides a magazine milling tooling fixture, including:

[0006] A rotary table;

[0007] A base plate, detachably connected to the rotary table;

[0008] A plurality of mounting seats are arranged on one side of the base plate, and a magazine core corresponding to the position of the mounting seat is arranged on the other side of the base plate;

[0009] A clamping mechanism, including pads, pressing blocks respectively arranged on both sides of the magazine, and a linear driving mechanism for driving the pressing block to press against the surface of the magazine.

[0010] Further, the rotary table includes a frame, pedestals symmetrically arranged on the frame, a driving mechanism arranged in one of the pedestals, and rotating seats respectively arranged on the opposite sides of the two pedestals. The base plate is arranged between the rotating seats.

[0011] Further, the cross-section of the rotating seat is L-shaped, and the base plate is detachably connected to the bottom plane of the rotating seat.

[0012] Further, the cushion block is arranged on the bottom plate and located between the bottom plate and the magazine, and the pressing block is in contact with the side of the magazine away from the bottom plate.

[0013] Further, the linear driving mechanism is arranged on the bottom plate, and the output end of the linear driving mechanism passes through the gap between the two magazines and is connected to the pressing block.

[0014] Further, the linear driving mechanism is a hydraulic cylinder arranged on the bottom plate.

[0015] Further, a clamping block matching with the bottom of the magazine is arranged on the mounting seat, and the magazine core is sleeved with the top side wall of the magazine.

[0016] The principle and effect of this solution are as follows:

[0017] Compared with the prior art, the utility model first preliminarily installs and fixes the magazine through the mounting seat and the magazine core, and then uses the linear driving mechanism to drive the pressing block to move, so that the cooperation of the cushion block and the pressing block completely fixes the magazine. At the same time, the rotary workbench is used to drive the magazine to rotate for position adjustment, replacing the traditional magazine milling processing method of first milling, then wire cutting, and finally rotary milling. It can perform milling processing on the magazine simultaneously during a single machining process of the CNC machine tool, effectively avoiding the problem of poor product stability caused by multiple clamping, improving production efficiency, reducing production costs, and solving the problems of multiple clamping and multiple milling equipment required in traditional magazine milling, high labor costs, and poor product size stability.
