Description

Technical Field

[0001] The utility model belongs to the technical field of high-performance copper-tungsten alloy contact processing, and particularly relates to a high-performance copper-tungsten alloy contact processing device. Background Technique

[0002] Copper-tungsten contacts are generally used in high-voltage SF6 switches. During the use of the switches, tip burrs and surface oxidation will cause problems such as discharge and gas release during use. Therefore, it is required that the surface of the contact material has no burrs or oxidation.

[0003] During the processing of copper-tungsten contacts, it may be necessary to drill holes in the copper-tungsten contacts. After drilling, it is also necessary to grind the burrs in the holes. However, the existing copper-tungsten alloy contact processing devices can often only complete the drilling operation. Therefore, after drilling, the staff still needs to manually grind the holes, which is time-consuming and laborious. Moreover, the existing high-performance copper-tungsten alloy contact processing devices cannot be applied to copper-tungsten alloy contacts of different sizes. Summary of the Utility Model

[0004] The utility model provides a high-performance copper-tungsten alloy contact processing device, aiming to solve the problems that the existing high-performance copper-tungsten alloy contact processing devices cannot grind the burrs on the holes and cannot be applied to copper-tungsten alloy contacts of different sizes proposed in the above background technique.

The two longitudinal adjustment mechanisms at the bottom of the cross plate are one of the core parts of the device. They can precisely adjust the longitudinal spacing of multiple drills and multiple grinding rollers to ensure that when processing high-performance copper-tungsten alloy contacts, accurate drilling and grinding can be carried out according to the sizes and shapes of different contacts. At the same time, the two lateral adjustment mechanisms are respectively arranged on the two longitudinal adjustment mechanisms and can further adjust the lateral spacing of the drills and grinding rollers to meet the requirements of different processing layouts. This flexibility enables the device to process contacts of various complex shapes, greatly improving the processing efficiency and accuracy. Multiple drive motors with chucks are respectively arranged on the lateral adjustment mechanisms, providing a stable power source for the drills and grinding rollers. The chucks can firmly hold the drills and grinding rollers to ensure that they will not fall off or shake during high-speed rotation, further improving the processing quality and safety. Finally, the clamping and fixing mechanisms on the base are used to clamp and fix the high-performance copper-tungsten alloy contacts. These clamping mechanisms can firmly fix the contacts to prevent movement or deformation during processing and ensure the processing accuracy and product quality;

[0015] In summary, the high-performance copper-tungsten alloy contact processing device realizes the efficient and precise processing of high-performance copper-tungsten alloy contacts through its unique structural design. This device not only improves the processing efficiency and product quality but also reduces the production cost and the labor intensity of workers, having a broad market application prospect.
