Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vice device for an electric chain chisel machine which is used to cut holes in wood.

[Prior Art] A conventional chain chisel machine clamps and tightens a piece of wood as a workpiece parallel to the joint surface in a vise device installed at the bottom of the chain chisel machine's main body.
A chain chisel machine is known in which the body of the chain chisel is moved to a desired position in the front, rear, left and right directions, and the machine drills holes in wood. As a conventional vise device for a chain chisel machine, a device as shown in, for example, Japanese Utility Model Publication No. 54-32294 has been proposed. In the chain chisel machine shown in the above publication, the main body of the chain chisel machine, which has a chain blade driven by a motor, is supported by a base so that it can move up and down, and a pair of slide bars can slide on this base. , and both ends of a pair of slide bars protrude from both sides of the base. A fixed vise on the front side is slidably fitted to one side of these slide bars, and a vise holder is attached to the other side of these slide bars, and a spring is interposed in this vise holder. A movable vise is screwed into the movable vise through a slide bush so that its movement can be adjusted. The vise device of a conventional chain chisel machine is constructed as described above.The movable vise grips the wood that is in contact with the fixed vise, and after positioning the main body part in a predetermined position by sliding it in the front and back direction, The part is lowered and driven to drill a machined hole. However, with the conventional chain chisel machine, as shown in FIG. Since it is not possible to drill at an angle to S, it has not been possible to process joints with complex shapes such as so-called follow-up joints. For this reason, conventionally, in order to process joints with complex shapes, such as Oikake joints, it was necessary to make saw marks on the wood from the joint surface and carve it by hand, or use a large machine to shape the joints. Router processing was performed using a cutting tool to form the desired joint shape.

[Problems to be Solved by the Invention] With the conventional chain chisel machine having the above configuration, machining work is required only by hand in order to process the complicated joints as described above.
There was a problem in that the processing time was long. There was also the problem that the cost was too high when using a large machine. The present invention has been made in order to solve the above-mentioned conventional problems, and uses a vise device of a chain chisel machine to clamp a workpiece such as wood at a desired angle of inclination, and to cut a workpiece with a complicated shape such as a trailing joint. It is an object of the present invention to provide a vise device for a chain chisel machine that can process joints at low cost and with good workability.

[Means for Solving the Problems] A vise device for a chain chisel machine according to the present invention includes a base that movably supports a chain chisel machine body having a motor-driven chain blade, and a base that extends through the base. A pair of slide bars that slidably support the slide bar, a first vise attached to one side of the slide bar, and a vice holder attached to the other side of the slide bar, each of which is adjustable in movement. a vice, and a tilting vice whose one end is swingably supported on the first vice, and which is positioned so as to be adjustable to a desired tilt angle, and which holds the workpiece between the movable vice and the movable vice. It is something that Furthermore, it is effective to tilt and position the tilting vise by moving forward and backward movement of an adjustment rod that passes through both shafts that are rotatably fitted in the first vice and the tilting vice, respectively. Furthermore, it is preferable that a movable vice plate that clamps the workpiece is swingably attached to the movable vice. The main body may be configured to be slidable in a direction perpendicular to the slide bar. Further, after machining at least one machined hole that is inclined with respect to the side surface of the workpiece in the workpiece using the vise device of the chain chisel machine having the above-described configuration, a hole is formed between the machined hole and the side surface of the workpiece. Further, the workpiece may be brought into contact with an inclination vise positioned at a desired inclination angle, and after this workpiece is clamped by a moving vise, the main body may be cut as required in the front, rear, left, and right directions. While moving to the desired position, the chain blade is driven while lowering the main body to drill multiple machining holes that are inclined to the side surface of the workpiece, and then cutting is performed from the side surface toward these machining holes. It is also possible to form a trailing joint.

[Operation] According to the vise device for a chain chisel machine according to the present invention, there is provided a tilting vise whose one end is swingably supported on the first vise and which is adjustable and positioned at a desired tilt angle. As a result, it is possible to easily drill a machined hole that is inclined with respect to the joint surface of the workpiece, and the inclination angle of the machined hole can be freely set. In addition, by attaching the vise plate of the moving vise so that it can swing, the entire contact surface of the vise plate comes into pressure contact with the workpiece regardless of the inclination angle of the workpiece, clamping the workpiece and firmly securing it. Can be tightened. Furthermore, by configuring the main body to be able to slide in a direction perpendicular to the slide bar, even if the width of the chain blade is narrow and does not meet the machining hole size, machining can be performed while moving the main body, allowing the workpiece to be A machined hole of a desired length can be formed.

When the knob 41 is rotated and the push-out bolt 40 is threaded onto the shaft 27 of the front vice plate 7, the tilting vice plate 20 swings around the support shaft 22 and tilts to position B. At this time, both shafts 25 and 27 rotate slightly in the direction of arrow X (counterclockwise in FIG. 1) as the extrusion bolt 40 screws forward. Conversely, when the push-out bolt 40 is retreated to return the inclined vice plate 20 from position B to position A, the knob 41 is rotated in the opposite direction. At this time, both shafts 25,
27 rotates in the direction opposite to arrow X (clockwise in FIG. 1). In the vise device of the chain chisel machine configured as described above, hole drilling and joint processing are performed as follows. First, by rotating the knob 41, the push-out bolt 40 is rotated, and the tilt vice plate 20 is oscillated counterclockwise (FIG. 1) about the support shaft 22 to a required tilt angle θ, and is positioned. Next, the wood W is brought into contact with the contact surface 20a of the inclined vice plate 20, and the operating knob 33 is rotated to cause the moving vice plate 31 of the moving vice 30 to spiral toward the front vice plate 7 side and come into contact with it. , the wood W is clamped and fixed between the inclined vice plate 20 and the movable vice plate 31. Next, while lowering the main body 1 of the chain chisel machine (FIG. 4), the chain blade is rotated to machine the hole 70 in the wood W (see FIG. 6). At this time, when the main body 1 is slid in the left-right direction (left-right direction in FIG. 1) while in the driven state, the inclined hole (machined hole) 70 corresponding to the inclination angle θ of the inclined vice plate 20
is machined, and this inclined hole 70 has an inclined angle θ with respect to the joint surface (side surface) S. Furthermore, while positioning the main body 1 at predetermined positions in the left-right direction (left-right direction in FIG. 1) and front-back direction (up-down direction in FIG. 1),
