CN-116887945-B - Control panel and lathe

Abstract

The invention provides a control panel and a machine tool capable of preventing a fan from being involved in foreign matters. A control panel (20) houses electrical components for controlling a machine tool in a housing box (21). A heat radiation mechanism, a fan (50) and a cover (30) are arranged on the left wall (202) of a storage box (21) of the control panel (20). The heat dissipation mechanism is partially disposed inside the storage box (21) and is connected to the electrical component. The fan (50) is fixed to the left side of the left wall (202) of the control panel (20) via a housing. The fan (50) is positioned at the lower side of the heat dissipation mechanism. A fan (50) supplies air to the heat radiation mechanism through the housing. A cover (30) covers the outside of the blower (50). The left wall (301) of the hood (30) has an opening (31) that serves as an air supply port for the blower (50). The opening (31) is provided around a facing portion (310) of the left wall (301) that faces the fan (50).

Description

Control panel and lathe Technical Field The invention relates to a control panel and a machine tool. Background The machine tool described in patent document 1 includes a control panel. The control panel houses the electrical components. The heat sink part is provided on the side surface of the control panel and cools the electrical components housed in the control panel. The fin enclosure portion covers the heat sink portion. The fan introduces air into the sheet enclosure. Prior art literature Patent literature Patent document 1 Japanese patent laid-open publication 2016-221609 Disclosure of Invention Problems to be solved by the invention In the machine tool, in order to prevent the fan from being caught by a rod-shaped foreign matter (for example, a screw driver), a grid-shaped fan protector may be disposed at an inlet through which air is introduced into the fan. Even in this case, the rod-shaped foreign matter may enter from the gaps of the mesh, and the fan may be involved in the rod-shaped foreign matter. The invention aims to provide a control panel and a machine tool capable of preventing a fan from being involved in foreign matters. Solution for solving the problem A first aspect of the present invention provides a control panel including an electric component that controls a machine tool, a storage box that stores the electric component, a fan that is disposed outside a predetermined wall of the storage box, and a cover that covers the outside of the fan, the cover having an opening around a portion facing the fan. In the control panel according to the first aspect, since the opening is located around the opposing portion, even when a rod-shaped foreign matter enters the inside of the cover through the opening, the fan can be prevented from being caught in the foreign matter. In the first aspect, the control panel may further include a heat radiation mechanism connected to the electric component, a part of the heat radiation mechanism may be disposed outside the predetermined wall, the fan may be disposed so as to be aligned with the heat radiation mechanism in a predetermined direction parallel to the predetermined wall, and the opening may be located at a position other than a sandwiching position between the fan and the heat radiation mechanism in the predetermined direction in which the fan and the heat radiation mechanism are aligned. In the control panel, since the opening is not located at the sandwiching position, it is possible to suppress interference between wind introduced from the fan through the opening and wind sent from the fan toward the heat radiation mechanism. Therefore, the control panel can effectively release heat of the electric component from the heat radiation mechanism. In the first aspect, the opening may be located on at least one of one side and the other side of the opposite portion in a crossing direction crossing the predetermined direction. Since the control panel has the opening portion on at least one of the one side and the other side of the opposing portion in the intersecting direction, the cover can be miniaturized. In the first aspect, the cover may cover an outer side of the heat radiation mechanism, and a discharge port may be provided on a side opposite to the fan across the heat radiation mechanism in the predetermined direction, the discharge port opening the cover. In the control panel, the fan supplies air through an exhaust port located on the opposite side of the fan from the heat radiation mechanism, and the fan exhausts the outside of the wind shield after passing through the heat radiation mechanism. Since the temperature in the cover does not rise, the control panel can effectively release heat of the electrical component from the heat radiation mechanism. A second aspect of the present invention provides a machine tool including the control panel according to any one of claims 1 to 4. The machine tool according to the second aspect can achieve the same effects as the first aspect. Drawings Fig. 1 is a perspective view of a machine tool 1.
