Abstract
A cover structure of a machine tool, including a fixed cover for isolating the inside portion of the machine tool from the outside, the inside portion serving as a machining space, and a one-side opening type slide door for opening and closing an opening portion formed in the fixed cover, includes a stop structure portion for, when the slide door is closed, stopping the slide door at a predetermined distance away from the end surface of the opening portion of the fixed cover. The stop structure portion is provided on a portion of the slide door other than the closing-direction-side end surface of the slide door, or at a portion of the fixed cover other than the slide-door-closing-side end surface of the opening portion of the fixed cover.
Claims12
A cover structure of a machine tool including a fixed cover for isolating the inside portion of the machine tool from the outside, the inside portion serving as a machining space, and at least one slide door configured to open or close an opening formed in the fixed cover, wherein
- the cover structure comprises a stop structure configured to, when the slide door is moved in the closing direction, stop the slide door at a predetermined distance away from a first end surface of the opening of the fixed cover, the stop structure being provided on the fixed cover at a portion other than the first end surface of the opening of the fixed cover;
- the opening of the fixed cover has an end portion extending across the closing direction of the slide door, the end portion defining a second end surface of the opening, the first end surface opposite the second end surface in the closing direction;
- the stop structure is provided at the end portion of the opening of the fixed cover;
- and
- in a closed position of the slide door, the slide door engages the stop structure and is spaced, in the closing direction, at the predetermined distance away from the first end surface of the opening of the fixed cover.
A cover structure of a machine tool including a fixed cover for isolating the inside portion of the machine tool from the outside, the inside portion serving as a machining space, and at least one slide door configured to open or close an opening formed in the fixed cover, wherein
- the opening of the fixed cover has a first end rim, a second end rim, a top rim and a bottom rim therein;
- at least one electronic device is disposed in the fixed cover adjacent to the second end rim;
- the slide door is configured to be slid in a closing direction from the first end rim toward the second end rim of the opening to close the opening in the fixed cover;
- the cover structure comprises a stop structure provided at at least one of the top rim or the bottom rim of the opening and configured to stop the slide door when the slide door is moved in the closing direction so as to keep the slide door at the predetermined distance away from the second end rim of the opening of the fixed cover, thereby preventing the slide door from directly contacting the fixed cover and reducing the possibility of breakage of the electronic device;
- and
- in a closed position of the slide door, the slide door engages the stop structure and is spaced, in the closing direction, at the predetermined distance away from the second end rim of the opening of the fixed cover.
