Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a material support for a tenon machine.

[Conventional technology]

A material support base used in a conventional tenoning machine will be described with reference to FIG.

2. Description of the Related Art Conventionally, when a long material is clamped to a vise table by a tenon machine, a support base is used to support the long material that protrudes greatly from the tenon machine. This support base has a column 2 suspended from the center of a base 1, and a frame 3 is horizontally disposed on the upper part of the column 2. Arrange 14
The material 12 is supported by the rollers 14.

[Problems to be solved by the invention]

Clamp the twisted material into the mortise machine vise table,
When the material 12 is supported by the roller 14, the material 12 may be detached from the roller 14 because the material 12 is largely bent from the vise table.

Further, for example, in a tenon machine having a vice tilting device as shown in Japanese Utility Model Publication No. 2-15607, when the vise table is tilted while the material is clamped on the vise table,
Since the material also tilts and the center of gravity of the material moves, there is a problem that the load balance of the material is lost, the load applied to the roller changes, and the support falls. For this reason, it was necessary to insert a wedge under the support and tilt it, or to move the support to the core of the material to achieve balance.

Furthermore, when the material is rotated by 90 ° and the tenoning is continued after the material is tenoned, when the material is rotated by 90 °, the cores of the vise table and the support table are displaced, and the support table similarly falls down.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art and to provide a support that can stably support a material against twisting of the material and inclination of the vise table.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a roller provided on a column suspended from a base so as to face a V-shape, and the roller is rotatably and axially movably supported. Elastic materials are provided at both ends.

[Action]

With the above-described configuration, when the material is placed on the roller facing the V-shape and the material is tilted, the center of gravity of the material moves, and the load applied to the roller changes because the load balance of the material is lost. In response to the loss of the load balance, the roller moves in the axial direction, and the elastic material is extended or compressed with the movement of the roller, so that the load balance of the material can be maintained.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a front view of a support base showing one embodiment of the present invention,
2 is a side view of FIG.

In the drawing, a column 2 is suspended from the center of a base 1, and a frame 3 is arranged on the upper portion of the column 2 so as to face each other in a V shape.
Rollers 4 and 5 have shafts 6 and 7 on the left and right frames 3, respectively.
The roller 4 is rotatably supported by the roller 4. At both ends of the roller 4, a spring 8, which is an elastic material so that the roller 4 is movable in the axial direction,
9 are provided, and springs 10 and 11 serving as elastic materials are also provided at both ends of the roller 5.

In the above configuration, one end of the material 12 is clamped to a vise table of a tenon machine (not shown), and
Put on top. Here, for example, when the material 12 is inclined (rotated) in the direction a, the center of gravity of the material 12 moves, so that the load balance of the material 12 is lost and the load applied to the rollers 4 and 5 changes. Since the axial direction is urged by the springs 8, 9, 10, and 11, the roller 4 moves downward as shown by a two-dot chain line in FIG. Then, the spring 8 on the roller 4 side is extended, the spring 9 is compressed, the roller 5 moves upward, the spring 10 on the roller 4 side is compressed, and the spring 11 is extended. Thus, self-alignment is performed by maintaining the load balance.

In addition, even if the material 12 is arbitrarily placed on the rollers 4 and 5, the rollers 4 and 5 are V-shaped, so that the material 12 is always set to the core position of the material 12.

[Effect of the invention]

According to the present invention, the rollers of the material support table are arranged in a V-shape facing each other, and the rollers are urged by springs from both ends. Can be supported in position.

Further, when the material is inclined, the core of the material can be automatically adjusted, so that the material can be reliably supported.
