Description

A universal tool for drilling holes for workpieces supported by uprights

technical field

The utility model relates to the technical field of drilling tooling, in particular to a universal tooling for drilling a workpiece supported by a vertical column.

Background technique

The full name of tooling is process equipment. In addition to production equipment and tools in the production enterprise, in order to meet the production equipment and personnel to complete the process production requirements, drilling tooling is one of them.

For special hydraulic supports such as gantry supports and self-moving equipment trains to support the top cover, drilling operations are required during the processing. The traditional drilling method is usually to fix the scribed column support top cover on the working surface of the drilling machine through the pressure plate, and then drill according to the drilling scribe line. Although the drilling operation is finally completed, it has the following defects: 1. It is necessary to carry out drilling and marking in advance. The marking process is not only time-consuming, resulting in low processing efficiency, but also there are human errors in marking, and the processing quality is not easy to guarantee; Second, the column support top cover is composed of two parts: the base and the pressure plate. It is easy to cause the hole position deviation of the machined hole and the increase of the diameter of the hole, which seriously affects the shape and position accuracy of the hole. Therefore, the original drilling method is difficult to guarantee the quality requirements.
