Description

Technical field:

[0001] The utility model relates to the technical field of woodworking processing equipment, and more specifically to an improved drilling machine for woodworking. Background technology:

[0002] A drilling machine is a machine tool that mainly uses a drill to make holes on a workpiece. Usually, the rotation of the drill is the main motion, and the axial movement of the drill is the feed motion. The drilling machine has a simple structure and relatively low processing accuracy. It can drill through holes and blind holes. By replacing special tools, it can expand, countersink, ream holes or perform tapping and other processing. During the processing, the workpiece does not move, and the tool moves to align the center of the tool with the center of the hole, and the tool rotates (main motion).

[0003] The drilling machine can not only process metal parts and plastic parts, but also wood. However, the existing conventional drilling machines generally have a fixed clamping table, and cannot be connected at high and low positions as needed. When clamping materials of low height, it is necessary to fix a raising component on the top surface of the clamping table, and then fix the material on the top surface of the raising component before processing. The raising block is troublesome to install, and different raising blocks are required for different heights, which makes adjustment troublesome. At the same time, it can only clamp one workpiece at a time and process one hole in it. After processing, it needs to be disassembled and installed to process another workpiece, which is inefficient. Utility model content:

[0004] The purpose of the utility model is to provide an improved drilling machine for woodworking in view of the deficiencies of the prior art. A movable clamping plate that can move forward and backward is installed on its horizontal support plate, which can clamp multiple workpieces at a time, and the movable clamping plate can be moved forward and backward, so that all the workpieces clamped thereon can be moved forward and backward, and the corresponding positions of each workpiece can be drilled one by one without multiple loading and unloading, thereby greatly improving the processing efficiency.
