Description

Technical Field

[0001] The utility model relates to the field of anodized aluminum guide rod processing, in particular to an automatic milling and chamfering machine for anodized aluminum guide rods. Background Art

[0002] The anode aluminum guide rod is a conductor used to connect the parallel busbars on the upper part of the electrolytic cell and the anode steel claw in the aluminum electrolysis process. It plays the role of conducting electricity and suspending the anode carbon block. At present, there is an interface layer formed by the mutual diffusion of aluminum and steel at the joint of the aluminum guide rod and the steel claw. Due to the difference in the physical and chemical properties of the two materials, there are certain differences in the mechanical properties, conductive properties, etc. between the joint area and other parts. Therefore, the requirements for welding are relatively high.

[0003] In the existing technology, the connection between the old guide rod and the new steel claw includes two methods: manual welding and automatic welding. Manual welding does not require consideration of the chamfer size and whether the end face is flat. However, the chamfers are all cut with a circular saw blade, requiring manual fixing of the guide rod and manual operation of the sawing, which poses a significant safety hazard and is complex to operate. Automatic welding, on the other hand, requires high consistency in the chamfer dimensions of the guide rod. To ensure the consistency of the chamfer dimensions, it is usually necessary to first use a milling machine to mill each surface of the guide rod, which requires the production of corresponding tooling. Moreover, since the overall dimensions of the old guide rods vary, the milling machine fixture needs to be adjusted according to the actual situation each time. After the milling is completed, the guide rod is chamfered. After the chamfering of one side is completed, it is manually flipped over and each side is chamfered in turn. After the chamfering is completed, the product is taken off the production line.

[0004] With the development of technology, some anode guide rod chamfering processing devices have also appeared in the existing technology. For example, the CN204171423U patent discloses an anode guide rod chamfering processing device, in which the machine tool base is provided with an anode guide rod fixing device and a chamfering milling device, wherein the anode guide rod fixing device is composed of a turntable support frame and a turntable mechanism connected to the machine tool base. However, the structure of the device is not compact enough and can only realize the guide rod chamfering processing. In order to improve the processing efficiency, some other devices are designed to be able to process multiple guide rods at one time. For example, the CN215508997U patent discloses an anode guide rod chamfering processing device, which uses multiple three-jaw chucks to clamp multiple anode guide rods at the same time, and performs chamfering operations on multiple anode guide rods at one time by moving the turning tool. For example, the CN210451186U patent discloses an anode guide rod chamfering machine, which places multiple anode guide rods on a material receiving table, and then uses a feed mechanism to drive the material receiving table to move and cooperates with the sawing units on both sides to complete the processing.
