Description

technical field [0001] The invention relates to a milling machine, in particular to an electric universal milling and drilling device for 360-degree rotating positioning of a milling head. Background technique [0002] Milling machine is an indispensable general-purpose equipment in the machinery manufacturing industry, and it is also a high-yield machine tool in the machine tool industry after the output of lathes. Existing milling machines are mainly of horizontal or vertical structure, which not only has a single function, but also has a large bed volume, and the processing stroke of the milling head is limited, so parts cannot be milled, bored, drilled, etc. It is difficult for a milling machine to process the slope of the workpiece, so for the processing of irregular parts, it often needs to be clamped multiple times or on a variety of machine tools.

Problems solved by technology

Existing milling machines are mainly of horizontal or vertical structure, which not only has a single function, but also has a large bed volume, and the processing stroke of the milling head is limited, so parts cannot be milled, bored, drilled, etc. It is difficult for a milling machine to process the slope of the workpiece, so for the processing of irregular parts, it often needs to be clamped multiple times or on a variety of machine tools. It can only be completed on a special machine tool, not only the operation is cumbersome, the processing efficiency is low, but the production cost is also high

The existing milling machine is difficult to disassemble and assemble the milling head. During the processing and production process, it is often shut down for maintenance due to the damage of the milling head.

Therefore, the existing milling machines have the disadvantages of large size, single function, cumbersome processing operations, difficult disassembly and assembly of the milling head, and low processing and maintenance efficiency.

[0003] The inventor invented such as: "portable three-axis rotary positioning universal milling machine", "magnetic rear pull rod positioning rotary universal milling machine", "shaft holding positioning rotary universal milling machine" and other small However, in the follow-up use, the inventor found that although the problem of adjusting the milling and drilling direction by the rotation of the milling head was solved, the positions of the milling head and the base of the machine tool were relatively fixed, and the position of the milling head during actual production and processing The connection method still has certain limitations, and the adjustment range of the processing position is limited. Especially when working in a small and narrow processing area, the base of the machine tool often becomes an important factor restricting the processing position of the washing head. If the extension rod is simply used to connect the milling head to solve This problem, however, cannot achieve the purpose of adjusting the direction of milling and drilling, and the disassembly and assembly of the extension rod is complicated, and it is also difficult to stably connect the extension rod to the machine base, so it is still relatively difficult to process and use; and it is difficult to move the column axially during construction in a narrow processing area At the same time, it is difficult to perform manual rotation, and the rotation accuracy is low, not only the construction efficiency is not high, but also the construction accuracy is difficult to guarantee

[0004] Therefore, the current milling machine has the problems of large volume of milling machine and single function of the milling head, while the connection mode of the milling head of the small universal milling machine is limited, the adjustment range of the processing position of the milling head is limited, and the connection stability of the connecting device is poor. The problem of complex disassembly and assembly of the connecting piece device makes it difficult to use the milling machine; there are also problems such as the difficulty in the axial movement of the column and the low precision of the column rotation, not only the construction efficiency is not high, but the construction accuracy is also poor
