When the pressing leaf springs 114 are attached to face each other via the mounting screws 113 and the handle 112a is rotated,
The presser plate 114 is moved back and forth in a fine motion so as to face the main vise frame 102.

[Problems to be solved by the device]

However, in the clamping device having the above-described structure, when clamping the side surface of the wood W to be processed by the pressing leaf spring 114, first of all, the auxiliary vise frame 103 is first.
The support pipe 107 is positioned with respect to, and then the clamp screw 112 is positioned to position the holding leaf spring 114. That is, the stopper 108 is first pulled out from the support pipe 107, and then the support pipe 1
Move 07 properly in the axial direction of the clamp device and insert the desired insertion hole.
107a is opposed to the through hole 103b of the auxiliary vise frame 103, and then the stopper 108 is inserted through the through hole 103b and the insertion hole 1.
It is penetrated through 07a, and thus the pressing leaf spring 114 is roughly positioned. Then, the handle 112a of the clamp screw 112 is rotated to appropriately move the clamp screw 112 in the longitudinal direction of the clamp device so as to move the leaf spring 114 and the wood W.
Then, the operating lever 105 is pulled and the leaf spring 114 is pressed against the side surface of the wood W, and the leaf spring 114 is locked to the stopper portion 103a for clamping. As described above, when positioning the leaf spring 114 in the vicinity of the wood W, a two-step operation is necessary, and the operation is complicated.

In view of this point, the present invention has an object to provide a clamp device for a wood working machine, which can easily position an elastic pressing member for clamping the wood when the wood to be processed is clamped. To do.

[Means for Solving the Problems]

Wherein the clamping mechanism for operating the actuating lever from the main device frame side is provided; that a is provided so as to be stationary at any position.

[Action]

When clamping the wood to be processed, with the actuating lever released from the stop mechanism, the coupling mechanism is loosened and the vice bar member is slid in the axial direction of the clamping device and elastically pressed to the appropriate position. Position the part. Then, the connecting mechanism is tightened to fix the relative position of the clamp bar member, that is, the elastic pressing member and the operating lever, and the operating lever is operated directly in the direction of the wood to be machined or via the connecting bar. By swinging from the side, the stop mechanism is operated to maintain the state in which the elastic pressing member presses the side surface of the wood to be processed with an appropriate pressing force. In this way, if the elastic pressing member for pressing the wood to be processed is positioned steplessly by one operation, and the clamping operation and the releasing operation are performed by the swing of the operating lever, the operation should be performed by a simple operation. The wood can be reliably clamped.
