Description

[Detailed Description of the Invention] The present invention relates to a plate notching device for notching a plate, a so-called sizing device for a corner shear.

A plate cutting device such as a corner shear is configured with a table having V-shaped lower blades that are perpendicular to each other, and a T-groove parallel to each lower blade is formed on the upper surface of the table. There is. A sizing device for positioning the plate is movably fixed in the T-slot.

As a conventional plate material notching device, for example,
The configuration is as shown in Japanese Utility Model Publication No. 11028 and Japanese Utility Model Publication No. 52-41669, and the sizing device (stopper) in each device is used by the operator to move and position along the T-groove. At this time, there is no problem when the sizing device is moved largely along the T-groove, but it is necessary to move only a small distance so that the scale of the vernier of the sizing device is accurately aligned with the scale. In that case, it was rather troublesome.

That is, in the past, since it took a relatively long time to accurately position the sizing device, there was a problem in improving work efficiency in high-mix, low-volume production.

As a means to solve the above conventional problems, it is also possible to provide a movable block that can be moved and fixed along the T-groove, and to connect this movable block and the sizing device with adjustment bolts. be. However, in this configuration, after the movable block and the sizing device are moved together along the T-slot, the movable block is fixed, and then the adjusting bolt is operated to finely adjust the sizing device. Become.

That is, in the above configuration, when moving the sizing device along the T-groove, two operations are required: one to release the fixation of the sizing device to the T-groove, and the other to release the fixation of the movable block. . Furthermore, when fixing, it is necessary to fix the movable block and finely adjust the sizing device, and then fix the sizing device. Therefore, when moving and fixing the sizing device, it is necessary to release and fix the sizing device and the movable block twice, respectively, resulting in a troublesome operation.

This invention was made in view of the above-mentioned problems, and aims to provide a device that can extremely easily make fine adjustments to the sizing device after it has been moved a large distance along the T-slot. It is something.
