It is mainly used for machining high-precision holes or finishing multiple holes in one positioning. In addition, it can also be used for machining other machined surfaces related to the finishing of holes. Using different tools and accessories, drilling, milling, and cutting can also be carried out. The machining accuracy and surface quality are higher than those of drilling machines. The boring machine is the main equipment for machining large box parts. Threads and machining the outer circle and end face, etc.

[0003] Due to the good finishing effect of the boring machine, it is widely used in the production of various parts, such as pumping unit fitters. However, there are design defects in the factory of the sector gear in the original digital display horizontal boring machine equipment in the existing pumping unit fitter workshop. The rear end shaft of the sector gear is relatively thin. During use, it will be damaged on average every 2.5 months. It is necessary to replace the new sector gear after the production stops, which has a great impact on production. At the same time, each time the sector gear is replaced, not only materials but also labor costs need to be spent, which further increases the maintenance cost and cannot meet the production requirements. Therefore, a sector gear for a boring machine is proposed to solve the problems raised above. Content of the Utility Model
