[0002] The row drilling machine converts the traditional manual row drilling action into a mechanical action and automatically completes it by machinery. The row drilling machine can be divided into two types: one is a semi-automatic row drilling machine, that is, after the machine arranges the diamonds into the diamond template, it is then manually pasted, reducing the labor intensity and eliminating the need for skills training. The other is a fully automatic row drilling machine, which can automatically set the template, avoiding the technical problems of manual template setting, saving labor, improving production efficiency, and reducing labor costs.

[0003] The milling head belongs to the power component. The power component is a component that provides the main movement and feed movement for the combined machine tool. There are mainly milling power heads, power boxes, cutting heads, boring tool heads, and power slides. The supporting components are components used to install power slides, cutting heads with feed mechanisms, or fixtures, etc., and include side bases, intermediate bases, brackets, adjustable brackets, columns, and column bases, etc.

[0004] However, in the process of installing and disassembling the cutting head, it is found that there are at least the following technical problems:

[0005] 1. During the use of the cutting rod, due to the large amount of grinding during processing, it is necessary to frequently install and disassemble, and it is difficult to control the processing accuracy of manual installation;

[0006] 2. Among them, the cutting rod will bear a large lateral force during use, and a lateral support mechanism is provided to increase the structural stability and improve the problem of lateral processing support of the cutting head. For this reason, we propose a quick replacement structure of the cutting head of a row drilling machine. Content of the Utility Model
