Then, the face plate 5 is attached from the upper surface of the frame 3 on the work table 9a of the work table 9 for attaching the face plate, and the wooden panel as shown in FIG. 9 is manufactured.

[Problems to be Solved by the Invention] By the way, in the above-mentioned conventional method for manufacturing the wooden panel frame 3, on the work tables 6a, 7a having a flat upper surface,
Vertical and horizontal frame members 1a and 1b and reinforcing core material 2 that have been subjected to the complementary groove processing
Frame 3 by aligning a and 2b with each other
Is assembled. Therefore, in the conventional framework work, there are many parts that depend on the experience and intuition of the worker, and the skill of the worker is required.

Therefore, as a result of earnest research to solve the above-mentioned problems, the present inventor has set a guide pin for positioning and fixing a frame material, a reinforcing core material, and the like on a work table to be framed so that dimensional accuracy is predetermined and the guide pin can freely appear and disappear. If it is installed, the frame and core can be framed by relying on this guide pin, which led to the idea that the quality can be improved (filed on December 27, 1991 for "wooden panels". Frame manufacturing equipment ").

In the above technology, a fixed type work table is provided with a cylindrical guide pin that moves up and down via a push-pull wire. There remains a problem to be solved such that the work table as a whole cannot be made portable by framing the work core material.

The present invention has been proposed in view of the above circumstances, and an object thereof is to accurately position a frame material, a reinforcing core material, and the like, and to make the entire work table for framing portable. It is an object of the present invention to provide a positioning mechanism for assembling a wooden frame.

“Means for Solving the Problem” In order to achieve the above object, the present invention assembles a frame body in a square frame shape by a frame member on the upper surface of a work table,
A positioning mechanism for positioning the frame or reinforcing core on the upper surface of the work table when manufacturing the frame by arranging reinforcing cores assembled in at least a vertical and horizontal cross shape inside the frame. And a spring body that is vertically rotatable through a hinge pin in a mounting hole that penetrates the upper surface of the work table to the front and back and that has a spring body that presses the side surface of the frame or reinforcing core material against its free end side. The tool pin, the cylinder device that pushes up the jig pin from the back of the work table with the rod to erect the jig pin, and the jig pin that is interposed between the base end of the jig pin and the edge of the mounting hole. And a jig member for urging the base end of the jig pin toward the base end side, and the jig pin and the hinge pin are vertically rotatable through a long hole extending in the longitudinal direction of the jig pin. It is characterized by being attached to.

"Operation" In the positioning mechanism according to the present invention, the jig pin can be raised by pushing up the jig pin from the back of the work table with the rod of the cylinder device. That is, when the jig pin is pushed up by the rod of the cylinder device, the jig pin vertically rotates about the hinge pin and is raised along the long hole. Therefore, in this state, it becomes possible to assemble the framework by relying on the jig pins.
