These accidents are more frequent and should be avoided when working at a night work or in a workshop where visibility is difficult to obtain, and when the worker's fatigue is high.
SUMMARY OF THE INVENTION The present invention has been conceived to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a cutter which is configured to expose a cutter while the cutter descends, And to provide a cutter including an auxiliary safety cover for reliably preventing a safety accident at a time.
In order to achieve the above-mentioned object, a cutting machine including an auxiliary safety cover according to the present invention,
bench;
A rotating frame rotatably mounted on the worktable;
A motor installed in the rotating frame;
A cutter installed in the rotary frame and having a cutter rotated by the motor,
Wherein the cutter covers a part of the outer circumferential surface of the cutter and a portion of the cutter of the protective cover which is exposed when the rotary frame is moved upwards and moves to open a portion where the cutter of the protective cover is exposed, And a link connection structure for connecting the auxiliary safety cover and the workbench.
The auxiliary safety cover includes a first auxiliary cover and a second auxiliary cover which are rotatably installed around a drive shaft on which the cutter is rotatably installed and are arranged to face each other along a circumferential direction of the drive shaft,
The link connection structure includes a first link that is rotatably connected to the first sub cover and a work table and a second link that is rotatably connected to the second sub cover and the first link .
The first link and the second link are disposed on the opposite sides of the portion where the auxiliary safety cover is disposed with respect to the drive shaft when viewed in the direction of the drive shaft.
And a portion of the first link near the drive shaft has a convex shape in the radial direction of the drive shaft.
And one end of the second link is connected to one point of the convex portion of the first link.
A guide hole is formed along the longitudinal direction of the first link so that the first link can move relative to the fixed point of the work table.
And the curvature of the guide hole has a sign opposite to the curvature of the convex portion.
And a slot is formed in the second link such that a moving point of the first link connected to the second link is rotatable relative to the second link.
And the opened portion of the protective cover, through which the cutter of the protective cover is exposed, is formed in a range of 180 degrees or less.
And the maximum height of the first sub cover is higher than the maximum height of the second sub cover when the rotating frame is in the raised position.
And the fixing point is located in front of the rotation center point of the rotary frame.
According to the cutter including the auxiliary safety cover of the above-described configuration, the cutter is exposed while the cutter is lowered for cutting, and gradually covers the cutter while the cutter is lifted to reliably prevent a safety accident in the cutting operation There is an advantage to be able to.
According to the present invention, a guide hole is formed in the first link along the longitudinal direction so that the first link can move relative to the fixed point of the work table, so that the first auxiliary cover and the second The auxiliary cover can be rotated with respect to the drive shaft, thereby facilitating maintenance.
