Cutting Machine

Abstract

The invention relates to manual tools, in particular to portable handheld cutting equipment and provides a cutting machine. A body comprises a disc-shaped cutter and a motor which is connected with the disc-shaped cutter and used for driving the disc-shaped cutter to conduct rotary cutting action. A protective cover is arranged above the disc-shaped cutter in a surrounding mode. The local edge of the disc-shaped cutter extends to the back side of a bottom plate. The cutting machine is characterized in that the body and the bottom plate are in hinged connection with a first hinge shaft as the shaft core; the first hinge shaft is parallel to the bottom plate and is arranged perpendicular to the rotary shaft core of the disc-shaped cutter; an arc-shaped guide rail is arranged on the bottom plate; the curvature center of the arc-shaped guide rail coincides with the first hinge shaft at the shaft core. The body is provided with a connecting piece which is connected with the arc-shaped guide rail in a matched mode, a locking unit used for locking and limiting relative displacement is arranged between the connecting piece and the arc-shaped guide rail, and thus the effect that an oblique face meeting the included angle requirement of a slope can be cut on the edge of a plate to be cut in the cutting process of the disc-shaped cutter is achieved.

Description

technical field [0001] The present invention relates to hand tools, in particular to portable hand-held cutting equipment. Background technique [0002] The shape and material characteristics of the workpiece are various. For example, the use of plates is very wide. It is also very common for plates as raw materials to be trimmed by cutting equipment. In some occasions, two adjacent plates or block materials need to be cut. The surface is chamfered or called slope cutting. As shown in Figure 1, the adjacent upper panel surface 1 and side panel surface 2 at one edge of the plate can be easily cut by using a cutting machine to cut the upper panel surface 1 and side panel surface 2 perpendicular to each other. The edge of the plate is processed into a slope 3, and at this time, the existing cutting machine is not up to the task. Especially when there is a requirement for the variation of the included angle α between the slope surface 3 and the upper plate surface 1, and the l...

Problems solved by technology

As shown in Figure 1, the adjacent upper panel surface 1 and side panel surface 2 at one edge of the plate can be easily cut by using a cutting machine to cut the upper panel surface 1 and side panel surface 2 perpendicular to each other. The edge of the plate is processed into a slope 3, at this time, the existing cutting machine is not up to the task

Especially when there is a requirement for the change of the angle α between the slope surface 3 and the upper plate surface 1, and the length L of the slope surface 3, the commercially available conventional cutting machine is powerless.
