Description

Barrel side drilling frock

Technical Field

The utility model belongs to the technical field of machining, and particularly relates to a barrel side drilling tool.

Background

In machining, it is often necessary to perform drilling operations on the sides of the cylinder, and to ensure even distribution of the holes on the outer circumference of the cylinder during drilling. The methods used in the prior art are manual scribing or machining with machining centers. The manual scribing has the defects of high scribing difficulty, time and labor waste in the process and high requirements on the skills of operators. The disadvantage of processing with a processing center is the occupation of equipment resources and high processing cost. In addition, because the outer circle of the part is an arc surface, the diamond is longer in overhanging, the drill bit is easy to drill off when directly contacting the workpiece, and the risk of the diamond breaking and the workpiece drilling waste is caused.

Therefore, it is necessary to design a drilling tool which reduces the difficulty of drilling and scribing, saves time and labor and has low processing cost.
