Embodiment Construction

[0048] Next, based on Figure 1 to Figure 14 Embodiments of the present invention will be described. Figure 1 ~ Figure 3 The whole of the cutting machine 1 mainly used for metal processing which has the cover apparatus 50 of this embodiment is shown. In this embodiment, a desktop grinder is illustrated as an example of the cutting machine 1 . This cutting machine 1 has a table 2 on which a cutting material is placed, and a cutting machine main body 10 supported by a main body support portion 3 provided on the table 2 so as to be able to tilt up and down. A vise device 4 for fixing cutting materials is provided on the upper surface of the workbench 2 .

[0049] The cutter main body 10 is supported by the main body support body 3 via the support shaft 5 so as to be able to tilt up and down. Such as image 3 As shown, the cutting machine main body 10 is equipped with various mechanism parts such as a reduction gear train in a main body casing 11 , and the lower part of the m...

Abstract

The present invention provides an outer cover device of cutting machine. In the cutting machine for processing metal, a movable outer cover which is closed through self weight is formed as the large weight of the movable outer cover that mainly covers the outer side of cutter. The movable outer cover which can be reliably closed through self weight can prevent the unclosing of movable outer cover caused from forgetting. The back side of a fixed outer cover (51) is installed with an opening position restricting component (70) which can return the opening position of the movable outer cover (51) to a position in which the gravity center G acts on the closing side through a spring acting force.

Description

technical field [0001] The present invention relates to a cover device for covering the cutting blade in a cutting machine in which a cutting machine body having a rotating cutting blade such as a circular grindstone or a saw blade is moved downward to cut a cutting material. [0002] In this specification, in addition to the processing form of separating the workpiece (so-called cutting), the cutting processing includes grooving processing in which the workpiece is not separated but cuts, grinding or cutting the workpiece, and the like. Therefore, the processed material to be cut is simply referred to as a cut material. Background technique [0003] In the past, a desktop cutting machine with a round grinding wheel and mainly used for metal processing has the following structure: the upper half of the grinding wheel is covered by a fixed cover fixed to the main body of the cutting machine, and the lower half of the range is opened. Covered by a closed movable cover, the mo...
