Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vise mechanism for a corner only machine.
[0002]
[Prior art]
A conventional corner only machine will be described with reference to FIGS. When the square hole 14 is machined into the hardwood 13 by the corner only machine, the thrust of 5 is increased only at the corner where the square hole 14 is opened, and thus a clamping force stronger than usual is required. In the normally used vices 26 and 27, the clamping force is insufficient, and the machine may slip only at the corner from the hardwood 13 and may not be able to perform hole processing. For this reason, for the purpose of improving the clamping force, the vise fixing bolt 25 is removed, the normal vice 26 and 27 are removed, and the hardwood vice 7 and 8 to which the needle pin 16 is attached is exchanged to clamp the hardwood 13. It is common.
[0003]
[Problems to be solved by the invention]
As described above, when using the hardwood vices 7 and 8 to which the needle pin 16 is attached from the normally used vices 26 and 27, the bolt 25 is removed using a tool and replaced with the hardwood vise 7 or 8. Therefore, work efficiency was poor and inconvenient. In addition, when processing the hardwood after processing the hardwood 13, it is necessary to replace the normal vice 26 and 27, and there is a similar problem.
[0004]
An object of the present invention is to improve work efficiency by changing to a vice having a different clamping force with one touch without using a tool.
[0005]
[Means for Solving the Problems]
The above object is achieved by rotatably attaching the sub device to the vice so that the front surface or the back surface of the sub device having the surface on which the needle pin is mounted, the back surface on which the needle pin is not mounted is located on the opposite surface of the pair of vices. Achieved.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The vice mechanism of the present invention will be described with reference to FIGS.
[0007]
Two columns 2 are suspended on the frame 15, and the column 2 is connected and fixed at the upper end by a bridge 3. The head portion 4 is supported by the column 2 so as to be movable up and down, and only a corner 5 is attached to the lower end. The head unit 4 is moved up and down by a motor 6 in the bridge 3.
[0008]
The frame 15 is fitted in a U-shaped groove (see FIG. 7) of the base 1 so as to be movable in the left-right direction, and a pair of vices 17 and 18 are provided below the base 1. The vices 17 and 18 are provided with holes 21 at appropriate positions, and a sub vice 19 is rotatably attached to the hole 21 portion with the shaft 20 as an axis. As shown in FIG. 3, the sub vice 19 has a needle pin 16 mounted on one side, that is, the front surface, and the needle pin 16 is not mounted on the other side, that is, the back surface. A hole for fitting the stopper pin 22 is provided on the upper surface of the sub vice 19, and the stopper pin 22 for fixing the sub vice 19 is disposed on the upper sides of the vices 17 and 18 while being pressed downward by a spring 23. . These vices 17 and 18 are provided facing each other so as to sandwich a side surface of a workpiece, for example, hardwood 13, and at least one of them is attached to the base 1 so as to be movable.
[0009]
In the above configuration, when processing the hardwood 13 after processing the softwood, pull up the stopper pin 22 disposed on the tops of the vices 17 and 18, release the fixing of the subdevice 19, press the subdevice 19 with a finger and rotate it 180 degrees, After the surfaces on which the needle pins 16 are mounted are made to face each other, when the stopper pins 22 are released, the stopper pins 22 are pushed down by springs 23 that pressurize the stopper pins 22 downward. The sub vice 19 is fixed by fitting. Thereafter, a machine is mounted only on the corners on the hardwood 13, one side of the hardwood 13 is brought into contact with the vice 17, and the other vice 18 is moved by the handle 9 to come into contact with the other side of the hardwood 13. Only the hardwood 13 and the corner are fixed by the retightening lever 10. The frame 15 is moved in the left / right and front / rear directions by the lateral feed handle 11 and the lever 12 to match the processing position. In this state, the motor 6 is activated to lower the head portion 4, and the square hole 14 is machined into the hardwood 13 with only the corner 5.

【The invention's effect】
According to the present invention, it is possible to change to a vice having a different clamping force with one touch without using a tool, and work efficiency can be improved.
