Description

Technical Field

[0001] The utility model belongs to the technical field of tooling, and in particular relates to a drilling tooling for a drilling pump random tool. Background Art

[0002] The drilling pump random tool is a random tool used to install the parts of the drilling pump. The structure of the random tool parts is as follows Figure 3 As shown, the random tool part is made of a cylindrical section and a square section, and a through hole needs to be processed on the cylindrical section. The central axis of the through hole is perpendicular to the central axis of the cylindrical section, and the central axis of the through hole is parallel to a set of diagonals of the square section. Due to the structural characteristics of the random tool part, it is inconvenient to fix the part on the drilling machine, and it is difficult to accurately position it during the fixing process to ensure that a set of diagonals of the square section is parallel to the central axis of the drill bit. The positioning and alignment time is long, which reduces work efficiency and cannot guarantee the processing accuracy of the through hole. Therefore, it is necessary to propose improvements.

[0009] As a further limitation of the above scheme, the distance a from the rear of the square tooling body to the center line of the drill guide hole is equal to the distance a′ from the end face of the cylindrical section on the random tool part to the center line of the through hole.
