[0002]

2. Description of the Related Art Conventionally, when processing a predetermined workpiece, a vise (vise device) has been used as a device for gripping and fixing the workpiece.
As is well known, this vise generally includes a fixed jaw fixed to the device body,
A movable jaw supported by the apparatus main body so that the movable jaw can move away from the fixed jaw, and the workpiece is clamped between the movable jaw and the fixed jaw by the approaching movement of the movable jaw with respect to the fixed jaw. That can be done.

By the way, in such a vise, when the apparatus main body is relatively large and the opening dimension between the fixed jaw and the movable jaw, that is, the moving distance of the movable jaw with respect to the fixed jaw is large, in many cases, A quick-moving mechanism for the movable jaw, a so-called fast-forward mechanism, is provided so that the movable jaw can move quickly. As a vise equipped with such a rapid traverse mechanism, the device can be moved closer to or away from the fixed jaw while being connected to the movable jaw via a spindle at the device body portion opposite to the fixed jaw with the movable jaw interposed therebetween. A plurality of pin insertion holes formed in the side surface of the apparatus main body at predetermined intervals in the moving direction of the slide member, and the slide member facing the side surface of the apparatus main body in the slide member. In the part,
A through hole formed with substantially the same diameter as the pin insertion hole,
Many of them include a pin insertion hole and a positioning pin that is removably inserted into the through hole.

That is, in a conventional vice with a rapid feed mechanism, while grasping a slide member or a movable jaw, they are integrally moved toward a fixed jaw to move through the through hole of the slide member and the apparatus body. At an arbitrary position corresponding to one of the plurality of pin insertion holes, a positioning pin is inserted into the through hole and the pin insertion hole from the side, and the slide member is inserted into the device main body at the arbitrary position. Fix it immovable, then rotate the spindle,
By moving the movable jaw closer to the fixed jaw, a predetermined workpiece is clamped and fixed between the movable jaw and the fixed jaw.
The movable jaw can be moved quickly compared to a vice having no rapid traverse mechanism, which simply moves the movable jaw closer to the fixed jaw only by rotating the spindle, so that the movable jaw can be moved quickly. Speeding up can be easily achieved.

However, in a conventional vise provided with such a rapid feed mechanism, the fixing and release of the slide member at an arbitrary moving position with respect to the apparatus main body are performed by positioning the positioning pin with the through hole of the slide member and the apparatus main body. The pin insertion hole is formed by inserting or removing from the side from the side, so that, for example, a plurality of them are arranged in parallel next to each other on a table of a machining center or the like. When the adjacent jaws are arranged at a small interval, it is difficult or impossible to insert and remove the positioning pin. Cannot be performed stably, and as a result, the workability in the work of clamping the workpiece is significantly reduced. There had been caused.
