DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The multiple vice device of this embodiment has a fixed clamper 12 and a fixed clamper 1 on which a workpiece 10 as a workpiece to be subjected to predetermined processing is brought into contact and positioned.
2 and a movable clamper 14 that is provided so as to be movable toward 2. The work 10 is a long building material or other various members. As shown in FIG.
As shown in FIG. 5, a nut member 15 having a female screw formed on the inner peripheral surface is attached downward, and a driving screw shaft 16 having a square screw formed on the peripheral surface is screwed onto the nut member 15. Are arranged. The driving screw shaft 16 has one end supported by the fixed clamper 12 in a cantilevered manner and the other end supported by the fixed clamper 12.
It is placed in a free state. And fixed clamper 1
2 is a clamp base 1 in which a groove 17 having a U-shaped cross section is formed.
8, the base end is fixed in the groove 17. The screw shape of the screw shaft 16 may be a trapezoidal screw or the like in addition to the square screw.

On both side surfaces of the movable clamper 14 parallel to the screw shaft 16, the convex portions 2 having a length corresponding to the thickness of the movable clamper 14 are provided.
0 is formed. A pair of guide grooves 22 are formed on the inner surface of the clamp base 18 so as to face each other as guide portions, and the convex portions 20 of the movable clamper 14 are slidably fitted in the guide grooves 22. are doing.

A motor 24 as a drive device for rotating the screw shaft 16 is provided immediately below the screw shaft 16, and a first gear 26 is fixed to a rotary shaft 25 of the motor 24. A second gear 27 is fixed to one end of the screw shaft 16, and the first gear 26 and the second gear 27 mesh with each other. Therefore, the screw shaft 16 and the motor 24 are arranged on one side of the first and second gears 26 and 27. Then, the fixed clamper 12 and the movable clamper 1
4, the screw shaft 16 and the motor 24 form a set of vices 30.
Is composed.

This vise 30 is mounted on the clamp base 18
A plurality of sets, three sets in this embodiment, are attached in the axial direction of the screw shaft 16. The clamp table 18 is mounted on a rectangular integral pallet 32 having a predetermined size. A plurality of rails 34, in this embodiment, three rails 34 are formed on the pallet 32, and the fitting recesses 18 a of the clamp base 18 are slidably fitted on the rails 34. The clamp bases 18 to which the plurality of sets of vices 30 are attached are mounted on the pallet 32 in a plurality of rows in a direction orthogonal to the rails. And each clamp base 1
8 is a stopper 3 for fixing to the rail 34.
6 is attached.

Each pallet 32 has a clamp base 18
A motor 24 housed inside and provided for each vise 30
To the wiring 44 for supplying electricity as driving energy
Is provided. The wiring 44 is concentrated on the coupler 42 on the side of the pallet 32, and the coupler 42 is detachably provided to the connection portion of the power source 40 such as a power source.

Next, the method of use and the operation of the multiple vice device of this embodiment will be described. First, the clamp bases 18 are mounted on the pallet 32 in a plurality of rows at predetermined intervals, and are fixed by the stoppers 36 at predetermined positions. Then, the movable clamper 14 is opened, one side surface of the predetermined work 10 is brought into contact with the fixed clamper 12, and the work 10 is placed between the clamp bases 18. After that, the motor 24 is operated to move the movable clamper 14 toward the work.

At this time, the movable clamper 14 slides on the guide groove 22 with the convex portions 20 on both sides fitted in the guide groove 22. Here, the width of the convex portion 20 is equal to that of the movable clamper 1.
The length corresponding to the thickness of 4 is relatively long and can slide stably without rattling. Moreover, since the screw shaft 16 held in a cantilever state on the fixed clamper 12 is screwed and moved while being supported by the movable clamper 14, the screw shaft 16 is also supported more stably.

As a result, each movable clamper 14 is
The screw shaft 26 rotates to move to the fixed clamper 12 side until it comes into contact with the work 10. Then, it abuts on the work 10 and stops. Thereafter, the processing machine 46 performs a predetermined processing on the work 10. Here, even when the power supply from the power source 40 is cut off in a state where the movable clamper 14 is in contact with the work 10, the movable clamper 14 is retained at that position by the screw shaft 16 and the screw of the nut member 15, The clamping force for the work 10 does not become weak. Therefore, after that, the coupler 42 can be separated from the connection portion of the power source 40, and the pallet 32 can be conveyed to another processing position while holding the work 10 by the vise 30 to perform the next processing.

According to the multiple vice device of this embodiment, since the movable clamper 14 is screwed onto the screw shaft 16 and the movable clamper 14 is moved by the rotation of the screw shaft 16, a large movement stroke can be taken. Moreover, even if the power source is turned off, the movable clamper 14 reliably holds the position against the axial force of the screw shaft 16 due to the screwing of the screw shaft 16 and the nut member 15. Further, the motor 24 is arranged immediately below the screw shaft 16, and the first gear 26 on the motor 24 side is arranged.
And the driving force is transmitted by the meshing of the second gear 27 on the screw shaft 16 side and the first and second gears 26, 27 are housed in the fixed constant clamper 12, so that the entire configuration is extremely compact. Therefore, the distance between the vices 30 can be made close to each other, and the multiple connection can be easily achieved in the direction of the screw shaft 15.

The multiple vice device of the present invention may use an electric motor as well as an air motor as a drive device. In this case, the drive source is an air pump and the wiring 44 supplies air. It becomes a pipeline. The guide portion may be one in which a concave portion is formed on the movable clamper side and a convex portion is formed on the clamp base side, and the shape of the unevenness may be V-shaped or U-shaped, and the sliding surfaces are rubbed together. Is also good.

[0019]

According to the multiple vice device of the present invention, the driving device is arranged below the screw shaft, and the driving device can be arranged within the sliding range of the movable clamper. Serialization is easily possible. In particular, a plurality of vices can be arranged close to each other in the axial direction of the screw shaft. Further, by supporting the movable clamper by the guide portion, the screw shaft is also supported by the movable clamper, so that the sliding operation of the movable clamper becomes stable. Further, since the movable clamper is moved by the screw shaft, the movable clamper can maintain the clamped state even when the power of the drive device is cut off, and the workpiece is placed on the vise with the power source of the clamp cut off. The work can be transported together with the vise while being held.
