Built-in three-dimensional moving gun CNC vacuum electron beam welding machine

Abstract

The invention discloses a built-in type three-dimensional dynamic gun numerical control vacuum electron beam welding machine. The built-in type three-dimensional dynamic gun numerical control vacuum electron beam welding machine comprises a vacuum welding chamber, a built-in electronic gun, a working platform, a sliding door framework, a sliding door, a high-voltage power supply, an electronic control and numerical control device operating platform, a welding chamber vacuum system and an extraction platform, wherein the built-in electronic gun is arranged in the vacuum welding chamber; the working platform which is used for installing a workpiece is arranged at the bottom part of the vacuum welding chamber; the sliding door framework is matched with the vacuum welding chamber; the sliding door is used for closing the vacuum welding chamber; the welding chamber vacuum system is arranged outside the vacuum welding chamber and is communicated with the vacuum welding chamber, and the extraction platform is used for extracting the working platform; the built-in type three-dimensional dynamic gun numerical control vacuum electron beam welding machine is characterized in that the built-in electronic gun is arranged on a three-dimensional dynamic gun mechanism; the three-dimensional dynamic gun mechanism is arranged on the side wall of the vacuum welding chamber; the three-dimensional dynamic gun mechanism is connected with the electronic control and numerical control device. According to the built-in type three-dimensional dynamic gun numerical control vacuum electron beam welding machine disclosed by the invention, the vacuum welding chamber can be designed and manufactured according to the size which is slightly larger than the size of the workpiece, the size of the vacuum welding chamber is smaller, the power of a vacuum pump system which is adopted for vacuum pumping is smaller, the vacuum pumping time is shorter, the needed electricity is smaller, and the cost is reduced.

Description

technical field [0001] The invention relates to a vacuum electron beam welding device, which belongs to the field of vacuum electron beam welding, in particular to a built-in three-dimensional moving gun numerical control vacuum electron beam welding machine. Background technique [0002] Electron beam welding must be welded in a vacuum environment due to factors such as the great energy loss of the electron beam in the atmospheric state. [0003] Currently produced electron beam welding machines, the electron guns are all placed outside the vacuum welding chamber, and the electron gun is connected to the vacuum welding chamber through a fixed vacuum seal or a small-stroke unidirectional dynamic vacuum seal. In this way, its design and installation are relatively simple and easy to implement, but the problem is that the size of the vacuum welding chamber must usually be made more than 2 times larger than the workpiece to be welded to meet the requirements of the entire weldi...

AI Technical Summary

Problems solved by technology

It causes a substantial increase in the manufacturing materials and processing costs of the electron beam welding machine, as well as the power and time required for equipment operation. This cost increase is especially serious for occasions where large-scale workpieces need to be welded
