Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a multi-station combined drilling machine. Background Technique

[0002] A drilling machine mainly refers to a machine tool for processing holes in workpieces. Usually, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. The structure of the drilling machine is generally relatively simple, and the processing accuracy is relatively low. It can drill through holes and blind holes, and can also replace special tools to perform operations such as reaming, boring, or tapping.

[0003] In the prior art, a multi-station drilling machine can drill multiple groups of workpieces simultaneously or drill holes with different diameters for multiple different workpieces. In the existing multi-station combined drilling machine, a corresponding fixture is arranged under each drill bit for clamping the workpiece. However, according to the use requirements, for the same workpiece, holes with different diameters need to be drilled. During drilling, the workpiece needs to be successively clamped on the fixtures under the corresponding drill bits. After drilling, the staff needs to remove the workpiece and then clamp it under another type of drill bit. The frequent disassembly and assembly make the processing process more cumbersome, thus greatly increasing the workload of the staff and the labor intensity of the staff.
