Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door lock device for a splash guard installed in a machine tool or the like, and enables a one-touch operation with a release mechanism installed in a door grip.

[0002]

[Prior art and problems]

 Conventionally, as a typical example of a door lock device for a splash guard installed in a machine tool or the like, a door locking member composed of a ball and this ball receiver is mounted between the door and the splash guard. Since this door locking member is not a complete door lock device, the door often opens halfway due to mechanical vibration during cutting, etc., so that the external exposure of cutting chips and coolant and safety It becomes a missing state. Therefore, if a full-fledged door lock device is adopted, the door will not be in the half-opened state, but it will prevent operator intervention during cutting, so it is possible to temporarily inspect the inside of the machine or check the cutting state. You cannot open the door to check.

Further, in the complete door lock device, the opening / closing operation of the door is not easy, and the unlocking operation and the locking operation of the door must be performed at the same time of opening / closing the door. This complicates the unlocking operation and the locking operation of the door lock device, so that the door lock device must be used with the door lock device released.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a door lock device for a splash guard, in which a door release operation and a door lock operation are performed only by opening and closing the door.

[0005]

[Means for Solving the Problems]

 According to the present invention, in a splash guard having one or two doors, a hook metal is provided at one side of the door or at a contact portion of the splash guard with the door, and the hook is opposed to the door or the contact portion of the splash guard. The side door is equipped with a hook tool to which a spring restoring force is applied, and when the door is closed, the hook tool automatically locks to the metal fitting at the closing and connecting part, and the release push rod provided on the door grip is pushed. This is a door lock device for the splash guard that is configured to manually release the hook from the hook.

[0006]

[Action]

 The door lock device of the splash guard of the present invention is provided with a door grip as well as a hook tool equipped on this door is automatically locked by a hook metal fitting of the door closing and connecting part of the other side when the door is closed. The hook device can be manually released from the hanging metal fitting by pushing the release push rod, achieving both a complete door lock state and a simple manual release operation, providing a door lock device with high operability and safety.

【Example】

 Hereinafter, an example shown in the drawings will be described. FIG. 1 is a front view of a door lock device of a splash guard according to the present invention, FIG. 2 is a partial sectional view showing the door lock device, and FIG. 3 is a sectional view of a right side door showing the door lock device of the present invention. 4 is a front view of the door lock device of the present invention.

In FIG. 1, 10 is a machine tool, 1 is a bed, 2 is a column, 3 is a spindle, S is a bed 1 or a splash guard mounted on a table (not shown), and 4 and 5 are left and right. Doors 6 and 7 respectively indicate door grips. A door lock device 20 is provided on the back side of the closed portion of the two doors 6 and 7. Further, at the top of the door grip 7 of the right side door 5, there is provided a releasing push rod 24 for manually releasing the hook tool 21 from the hook 11 by a pushing operation.

Next, a detailed configuration of the door lock device will be described with reference to FIGS. A U-shaped mounting plate 12 is screwed on the upper side of the door grip 6 on the back side near the closing portion 4a of the door 4, and a tip-end 12a is provided with an inverted U-shaped hook 11. On the other hand, on the upper side of the door grip 7 on the rear surface side close to the closing part 5a of the door 5, there is provided a hook tool 21 to which the restoring force of the spring 23 in the clockwise direction is provided, and the upper trunk part 7a of the door grip 7 is provided. By pushing the release push rod 24 that is pierced, the tip 24a of the push rod 24 is brought into contact with the tail end 21a of the hook tool 21, and the thumb 25 pushes the release push rod operating portion 24b to compress the spring 25. 21 is rotated counterclockwise to manually release the engagement with the hook 11. With respect to the attachment structure of the hook tool 21, the hook tool 21 is pivotally supported by a support shaft 29 vertically entangled with the upper and lower support plates 27 and 28 of the base plate 26 integrally mounted with the upper trunk portion 7a of the door grip 7. The release push rod 24 is inserted and supported in a support hole 30a formed by screwing the support cylinder 30 into the upper trunk portion 7a of the door grip 7 from the rear side thereof. Thus, the tip 24a is projected to the outside.

In the door lock device 20 of the splash guard S of the present invention, when the doors 4 and 5 are closed, the hook tool 21 mounted on the door 5 is attached to the hook 11 of the closing / connecting portion 4a of the counterpart door 4. By sliding the taper portion 21b, the recess (a) is automatically locked and automatically locked. When the door is opened, the hook 21 can be manually released from the hook 11 by pushing the release push rod 24 provided on the door grip. In this state, the door can be opened easily by opening the door. Thus, it achieves both a complete door lock state, a simple manual unlocking operation, and a door opening, and provides a highly operable and safe operation.

It is needless to say that the present invention is not limited to the above-mentioned one embodiment, and design changes can be made within the scope of the invention. The embodiment of the drawings has been described with reference to the example of mounting the two-piece splash guard on the door, but the same applies to the case of mounting the one-piece splash guard on the door. In this embodiment, a release push rod and a hook member are provided on the door grip on the door side. Further, the relationship between the hook tool and the hook metal may be reversed, and the hook metal may be pivotally operated by the release push rod to release the hook metal.

[0012]

According to the present invention, a hook is provided on one side of a door or on a part of the splash guard that is closed and in contact with the door, and a restoring force of a spring is applied to the door or a door on the opposite side to the closed part of the splash guard. The hook is automatically locked to the hook at the closing / closing part when the door is closed, and the hook is manually released from the hook by pressing the release push rod provided on the door grip. Due to the configuration, the hook can be manually released from the hook by pushing the release push rod provided on the door grip, and both the complete door lock state and the simple manual release operation can be achieved, and the door has high operability and safety. It is effective in providing a locking device.
