Description

Technical Field

[0001] The present application relates to the technical field of welding equipment, and in particular to a milling and shaping tool for an electrode cap. Background Art

[0002] The electrode cap is a type of welding electrode used for welding of resistance welding equipment, such as single-sided spot welders, fixed spot welders, hanging spot welders, manipulator spot welders and robot spot welders. Because it is placed on the electrode connecting rod, it is called an electrode cap. The material is mostly chromium zirconium copper, and there is also dispersed copper. After a certain number of welding, the welding surface of the electrode cap will deform and wear, so that the electrode cap needs to be milled or replaced before continuing welding.

[0003] However, when conventional electrode cap milling and shaping tools are used in the prior art to mill and shape the electrode cap to repair the required shape, the copper-zinc alloy layer formed on the surface of the electrode cap is easily detached due to the vibration generated during milling and cannot be discharged in time due to its low hardness and fragility, and the chips are accumulated at the milling position of the blade, affecting the cutting effect; after milling, the front end face of the electrode cap is easily formed with ridges extending from the center of the end face to the circumference of the end face, or with spotted pits on the end face, and the required shape for welding cannot be achieved; this results in poor cutting effect and low product qualification rate. Summary of the invention

[0004] The embodiment of the present application provides a milling and shaping tool for an electrode cap, aiming to solve the problems of poor cutting effect and low product qualification rate when milling and shaping the electrode cap in the prior art methods.

[0005] In a first aspect, the present application discloses a milling shaping tool for an electrode cap, which is used for milling and shaping the electrode cap, and includes a milling shaping blade, a tool holder, and a cup head hexagon socket screw;

[0006] The tool holder is provided with a milling shaping blade positioning groove, the milling shaping blade is adapted to the milling shaping blade positioning groove, and the cup head hexagonal screw fixes the milling shaping blade in the milling shaping blade positioning groove; the blade surface of the milling shaping blade forms an acute angle with the horizontal plane.

[0007] The present application discloses a milling shaping tool for an electrode cap, which is used for milling and shaping the electrode cap, and includes a milling shaping blade, a tool holder, and a cup head hexagon socket screw; the tool holder is provided with a milling shaping blade positioning groove, the milling shaping blade is adapted to the milling shaping blade positioning groove, and the cup head hexagon socket screw fixes the milling shaping blade in the milling shaping blade positioning groove; the blade surface of the milling shaping blade forms an acute angle with the horizontal plane. The milling shaping tool of the electrode cap makes the electrode cap sharper when milling and shaping, which can reduce the grinding pressure, so that more copper chips of the electrode cap are cut off, rather than squeezed off, which will cause pits on the surface of the electrode cap, while cutting will make the surface of the electrode cap flat and smooth; and the cut copper chips can be quickly discharged without accumulation, and the surface of the electrode cap is smooth and round without edges and burrs after cutting and shaping, which significantly improves the cutting effect, thereby improving the welding quality and the product qualification rate.
