The clamper is attached to the lower end of the.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

Referring to FIG. 1, a horizontal band saw machine 1, which is an example of a cutting machine, includes a box-shaped base 3, a saw blade housing 5 that can be raised and lowered with respect to the base 3, and the like. The saw blade housing 5 is pivotally supported on the base 3 by a hinge shaft 7 so as to be vertically rotatable.

The saw blade housing 5 includes a base 3 and a saw blade housing 5
It is lifted up and down by the operation of the lift cylinder 9 interposed between and. In the saw blade housing 5, a drive wheel 13 and a driven wheel 15 around which an endless band saw blade 11 is wound are rotatably supported. The drive wheel 13 is driven by a drive device provided behind the saw blade housing 5, so that the band saw blade 11 is driven to travel so as to perform a cutting action.

The portion of the horizontal band saw blade 11 located in the cutting action area of the horizontal band saw blade 1 is slidably guided by a pair of guide members 17 and 19 so that the blade edge faces vertically downward. The pair of guide members 17 and 19 are the support arms 2 respectively.
The support arms 21 and 23 are appropriately attached to the lower end portions of the saw blades 1 and 23, and the support arms 21 and 23 are supported by the beam member 25 fixed at the upper position of the saw blade housing 5 so as to be positionally adjustable.

Further, a work table 27 on which a work W to be cut is placed is attached to a portion of the base 3 where the work W is to be cut, and a fixed vice jaw 29f and a movable vice jaw 29m for holding and fixing the work W are provided. The body vice device 29 provided is attached. Therefore, when the saw blade housing 5 is lowered from the raised position as shown by the phantom line in FIG.
The work W fixed to 7 is cut, and the work W can be cut. The cutting speed of the band saw blade 11 with respect to the work W can be controlled by appropriately controlling the elevating cylinder 9 to control the descending speed of the saw blade housing 5.

When a plurality of works W are placed on the work table 27 in a bundle and cut, the movable vice jaw 29m is moved to the right in the left-right direction in FIG. 1 with respect to the fixed vice device 29f of the main body vice device 29. A plurality of works W that have been moved and bundled are held and fixed. At this time, the plurality of bundled works W tend to float upward due to the clamping force of the main body vice device 29, and thus the plurality of bundled works W need to be pressed and fixed from above.

In order to press and fix a plurality of bundled works W from above,
A bundling vice device 31 is provided above the main body vice device 29. More specifically, as shown in FIG. 2, above the fixed vise jaw 29f and the movable vise jaw 29m of the main body vise device 29, the cylinder support 33 of the bundling vise device 31 is suspended. There is.

One end of the cylinder support 33 is a fixed vise jaw 2
9f is fixedly supported by a stand 37S and a nut 37N penetrating through the long hole 35, and the other end is supported by a stand 41S and a nut 41N penetrating through the long hole 39 so as to be freely movable left and right. Cylinder support 3
A cylinder 43 is integrally provided at the central portion of 3. A clamper 45 is fixed to the lower portion of the cylinder 43 via a piston rod, which will be described later in detail, which will be described in detail.

A cylinder cap 49 is attached to the upper part of the cylinder 43 with a plurality of bolts 47. The cylinder cap 49 has a hose 5 for supplying pressure oil, for example.
1 are connected via a hose adapter 53.

In order to prevent the clamper 45 from rotating with respect to the cylinder support base 33, a pin 55 for preventing rotation is attached to the clamper 45 by penetrating through a hole vertically formed in the cylinder support base 33.

Details of the internal structure of the cylinder 43 and the state of connection between the cylinder 43 and the clamper 45 are shown in FIG. In FIG. 3, the cylinder 5 has a piston 5
7, a spring 59 is interposed between the inner wall of the cylinder 43 and the outer wall of the piston 57 while being biased upward. A female screw is engraved on the inner circumference of the piston 57. A hollow rod 61 having a male thread screwed on the female thread and engraved on the outer periphery is mounted in the piston 57.

A female screw is engraved on the inner periphery of the hollow rod 61, and a piston rod 63 having an outer screw engraved on the outer periphery is attached to the hollow rod 61. A spring pin P is struck in the upper radial direction of the piston rod 63, and a hole H is formed in the hollow rod 61 in the radial direction as a hole for hitting or withdrawing the spring pin P. Therefore, the hollow rod 61
On the other hand, when the piston rod 63 moves up and down, the spring pin P hits the female thread of the hollow rod 61 and hits or is pulled out of the hole H. The hollow rod 61
The retaining of the piston 57 is also omitted although it is omitted in the drawing. An operation handle 65 is attached to the lower portion of the piston rod 63.

The spherical portion 67 integrated with the lower end of the piston rod 63 is rotatably fitted in a fitting hole 71 provided in the upper surface of the main clamper 69, and is held by a lid 73.

The clamper 45 is composed of the main clamper 69 and an auxiliary clamper 75 made of an elastic material such as urethane. The main clamper 69 is provided in the lower portion of the piston rod 63 as described above, and the spherical portion of the piston rod 63 is fitted in the fitting hole 71. 67 is fitted. The auxiliary clamper 75 is fixed to the main clamper 69 with bolts 77 from the left and right direction in the front and rear direction of the main clamper 69 in FIG.

The lengths of the two auxiliary clampers 75 are adjusted in the horizontal direction within the slot by adjusting the bolts 77 in the horizontal direction in FIG. 2 with respect to the main clamper 69.

With the above-described structure, the adjusting device for adjusting the height position of the clamper 45 first has the piston rod 6 when the operating handle 65 is rotated clockwise, for example, from below in the state shown in FIG.
Since the male screw drilled on the outer circumference of 3 and the female screw drilled on the inner circumference of the hollow rod 61 are screwed together, the piston rod 63 rotates relative to the hollow rod 61 and moves upward. If you continue to turn the operating handle 65, the operating handle 6
The upper surface of 5 abuts on the lower end of the hollow rod 61.

Further, when the operation handle 65 is rotated in the same direction, the piston rod 63 cannot move upward, and the male screw drilled on the outer circumference of the hollow rod 61 is screwed into the female screw drilled on the inner circumference of the piston 57. Therefore, the hollow rod 61 rotates with respect to the piston 57 and moves upward. Thus, the clamper 45 is moved to the lower end of the cylinder 41 as shown in FIG. By rotating the operation handle 65 in the opposite direction to the above, the operation handle 65 is lowered from FIG. 4 to FIG.

By operating the handle 65 of the adjusting device in this manner, the height positions of the hollow rod 61 and the piston rod 63 are adjusted, and the position of the clamper 45 is changed in the height direction from the state shown in FIG. 3 to the state shown in FIG. Will be adjusted by the stroke. Thus, the height position of the clamper 45 can be easily and easily adjusted in advance simply by operating the operation handle 65 according to the change in the height of the plurality of bundled works W. It is solved by the troublesome height position adjustment such as removing.

Next, a series of operations for holding and fixing a plurality of bundled works W will be described. First, the fixed vise jaw 29 that is fixed is fixed.

A plurality of works W are placed on the device 7 in a bundled state. In FIG. 2, the movable vice jaw 29m is moved rightward to clamp a plurality of bundled works W from the lateral direction.

The operation handle 65 is rotated clockwise, for example, when viewed from below in FIG. 3, and the position of the clamper 45 for pressing from the upper surface of the bundled workpieces W is adjusted in the height direction to the piston rods 63 and 61 of the adjusting device. Adjust and perform. The height position of the clamper 45 is adjusted in advance so as to be slightly higher than the height positions of the bundled works W. From the hydraulic drive (not shown) to the hose 5
1, for example, supply pressure oil via the hose adapter 53,
The piston 57 is pressed downward in FIG. 3 against the biasing force of the spring 59, and the plurality of works W bundled by the clamper 45 are pressed and fixed.

Further, in order to unclamp the clamper 45 from the upper surfaces of the plurality of bundled works W, the pressure oil is drained to lift the piston 57 upward by the urging force of the spring 59 and unclamp it.

The present invention is not limited to the above-mentioned embodiment,
It can be implemented in other modes by making appropriate changes.
