Abstract

The invention provides an aluminum part precision machining device for a camera. The aluminum part precision machining device for the camera comprises a bottom frame, wherein a bracket is fixedly connected to the bottom frame, a conveying belt is arranged on the bracket, and a plurality of U-shaped placing plates used for placing a cylindrical shell are fixedly connected to the conveying belt. The upper surface of the supporting block is arc-shaped, so that the inner wall of the cylinder shell can be better attached to the upper surface of the supporting block, and a stable and rigid support is provided for a punching area of the cylinder shell, and therefore the problem that the cylinder shell at a punching position deforms if the corresponding internal support is lacking at the punching position of the cylinder shell during punching due to the fact that the wall thickness of the camera aluminum cylinder shell is thinner is effectively avoided, and the punching precision and the processing quality of the cylinder shell are further affected.

Aluminum part precision machining device for camera Technical Field The application relates to the technical field of camera shell processing, in particular to an aluminum part precision processing device for a camera. Background The explosion-proof camera belongs to explosion-proof monitoring products, is a cross product of the explosion-proof industry and the monitoring industry, has the working principle of inhibiting generation and occurrence of four explosion elements, ensures that the electrical products can still work normally in high-risk environments, and is widely applied to dangerous places such as chemical factories, oil fields, coal mines and the like so as to effectively monitor safe production and accident occurrence. In the existing processing process of the aluminum shell of the camera, the aluminum shell of the camera is basically a cylindrical shell, and the wall thickness of the aluminum cylindrical shell of the camera is thinner, so that the existing aluminum cylindrical shell is usually sleeved on a punching column matched with the diameter of the aluminum cylindrical shell during punching, although the existing aluminum cylindrical shell can play a role in supporting and rigidly supporting the cylindrical shell, the diameter of the cylindrical shell is slightly smaller or slightly larger than the diameter of the punching column due to dimensional tolerance in actual production, when the diameter of the cylindrical shell is slightly smaller, the cylindrical shell is difficult to sleeve on the punching column, or the cylindrical shell is difficult to be in interference fit with the interference fit phenomenon which is difficult to insert and pull, so that clamping is difficult, and when the diameter of the cylindrical shell is slightly larger, a larger gap is formed between the cylindrical shell and the punching column, so that the cylindrical shell slightly moves during punching, and the punching precision is reduced, therefore, the conventional rigid punching column is difficult to adapt to the processing requirements of the cylindrical shells with different actual sizes, regardless of interference fit and clearance fit; Meanwhile, in the actual machining process, holes with different diameters often need to be machined in different positions on the cylindrical shell. When the existing equipment needs to be changed in processing position or changed in aperture size, the cylinder shell is usually required to be removed from the punching machine, clamped and positioned again, or the corresponding punching die is replaced. The repeated disassembly and assembly of the workpiece and the replacement of the die are extremely complicated, the machining efficiency is seriously affected, positioning errors are easily introduced by repeated clamping, the relative position precision among holes at different positions is difficult to ensure, and the follow-up accurate support of the machining position cannot be realized; in addition, after the stamping process is finished, burrs are often generated on the edges of the punched holes, and in order to ensure smoothness and flatness of the holes, additional manpower and polishing equipment are generally required to polish the burrs, so that the operation is troublesome, and the production cost is increased.
