Description

[Detailed description of the invention] This invention relates to a device for attaching a cover plate to the base of a machine tool.
The purpose is to devise a device for attaching a cover plate to the base of a machine tool that can be freely engaged and detached and has strong stability in use.

Another purpose is to hang the opened lid plate horizontally against the lower edge of the opening.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In each drawing, reference numeral 1 indicates one of the woodworking machines among the machine tools, and its base 2 has an opening 3 shaped like a square window.

Note that a screw seat 4 is provided in the middle of the upper edge of the opening 3.

Reference numeral 5 denotes a plate-shaped cover plate capable of covering the opening 3, and a fastening screw 6 is removably fitted in the middle of its upper edge, and is screwed into the screw seat 4.

In 7.7, the left and right pair of hooks are pieces, formed in the shape of a springboard, and have elasticity, and the upper ends 7a, 7a of the pieces 7, 7 are located under the cover plate 5. It is welded near the edge 5e, and the key end 7b is bent to protrude from the lower edge 5e of the cover plate 5 by a slight amount e in a substantially perpendicular direction.

Therefore, when the cover plate 5 is attached to the opening 3, the repulsive force due to the retreat of the protrusion amount e (displacement to the left in the figure) makes the lower edge 5e of the cover plate 5 firmly fixed.

Next, the functions and effects of the embodiment having the above configuration will be specifically explained.

First, the case of removing the cover plate 5 attached to the opening 3 of the base 2 will be explained. In this case, the upper tightening screw 6 is screwed back to release the upper part of the cover plate 5. When the hook rotates around the lower edge 5e of the plate 5 in the direction of the arrow shown in the figure (clockwise direction in the figure), the cover plate 5
Since the hook is tilted downward, the hook 7 is attached to the lower edge 3e of the opening 3.
The entire cover plate 5 can be removed from the opening 3 by removing it from the opening 3.

Note that covering the opening 3 with the lid plate 5 can be performed in the reverse order of the opening operation described above.

In particular, when the above-mentioned cover plate 5 is held horizontally as shown in FIG.
The horizontal state of the plate 5° is maintained by the clamping force of the lower edge 5e.

This is an effect unique to the present invention due to a configuration unique to the present invention.

In other words, the gist of the present invention is the configuration described in the registered claims, and the above-described effects are exhibited by the configuration, especially the unique configuration of the present invention in which the hook is provided with a piece. The device is extremely practical as a device for attaching the cover plate to the base of a machine tool, and has an excellent effect in that the cover plate can be removed from the opening.

In particular, in the device of the present invention, when the opened lid plate is hung horizontally on the lower edge 3e of the opening, the outer edge 7e of the key end 7b is Fitting the gap between the lower edge 5e of the cover plate and the lower edge 3e has a favorable effect as a means for horizontally holding the cover plate. This provides the effect of being able to be mounted.

[Brief explanation of the drawing]

The drawings show one embodiment of the present invention; Fig. 1 is a front view of the machine tool, Fig. 2 is a partial side sectional view showing the main parts, and Fig. 3 is an enlarged view showing the protruding state of the end of the cover plate key. The sectional view and FIG. 4 are enlarged sectional views showing the case where the lid plate is held in a horizontal state. 3e is the lower edge of the opening 3, 5e is the lower edge of the lid plate 5, 7b
The hook is the key end of the piece, and 7e is the outer end.

Claims (1)

[Scope of Claim for Utility Model Registration] A cover for a base of a machine tool, characterized in that a cover plate having the following structure is removably hung in a square window-shaped opening provided in the base of a machine tool. Board hanging device. (a) An elastic hook should be fixed to the upper end of the lower edge of the cover plate. (b) The outer end of the bent key end of the hook should protrude horizontally by a slight amount e from the lower edge of the cover plate. (c) When the opened lid plate is hung horizontally on the lower edge 3e of the opening, the lid plate is placed opposite to the same edge 7e as the outer edge 7e of the key end 7b. The structure is such that the gap between the lower edge 5e and the lower edge 3e fits into the lower edge 3e.
