Description

Technical Field

[0001] The utility model relates to the technical field of contact processing, in particular to a contact precision processing tool. Background Art

[0002] The contact is one of the key components of the switchgear. According to the structure and working characteristics, it can be divided into three categories: breakable contact, sliding contact and fixed contact. The main performance and life of the switchgear depend to a large extent on the quality of the contact material. The contact material is usually required to have good conductivity, low contact resistance, high resistance to fusion welding, high resistance to arc erosion and resistance to material transfer. For vacuum contact materials, it is also required to have a small cutoff value, high pressure resistance and high breaking capacity. The microstructure of the contact material has an important influence on its macroscopic performance. The electrical properties of the contact material, such as resistance to fusion welding, arc ablation resistance and pressure resistance, are not only related to the composition of the contact material, but also to the size of the grains of the constituent materials.

[0003] When processing contacts, it is necessary to clamp and fix the contacts, and then perform operations such as drilling and grinding on them. However, traditional processing jigs for contacts can generally only fix one contact at a time. The clamping operation of the next contact can only be performed after one contact completes the processing process. It is impossible to fix multiple contacts at one time, and it is even more impossible to directly operate multiple fixed contacts in sequence, which will cause a long delay in actual operation and reduce work efficiency.

After the template 11 is fixed, the contact is placed in the mold cavity of the template 11, wherein the template 11 only occupies a part of the contact, rather than the entire position of the contact being accommodated in the mold cavity. Therefore, most of the contact is directly exposed, which is convenient for processing operations. After the contact is placed in the mold cavity, the cylinder 9 is started, and the cylinder 9 drives the pressure block 10 to move downward, and the pressure block 10 is used to squeeze and fix the contact from the top, thereby facilitating the stable fixation of the contact.

The clamping rod 4 is used to clamp and fix the contact. In the specific operation, firstly, a template 11 adapted to the contact is installed on the clamping rod 4. The template 11 is fixed by the screws 12 at the bottom thereof. Therefore, the template 11 can be replaced to facilitate the clamping and fixing of workpieces of different shapes. After being fixed, the contact is placed in the mold cavity of the template 11, wherein the template 11 only occupies a part of the contact, rather than the entire position of the contact being accommodated in the mold cavity, so most of the position of the contact is directly exposed, which is convenient for processing operations. After the contact is placed in the mold cavity, the cylinder 9 is started, and the cylinder 9 drives the pressing block 10 to move downward, and the pressing block 10 is used to squeeze and fix the contact from the top, so as to facilitate the stable fixation of the contact.
