Referring to FIG. 1, FIG. 2 and FIG.
87 is provided in the base frame 7 so that it can be stored freely. That is, the transport frame 87 is a lower plate as shown in FIG.
89, front plate 91, rear plate 93, etc.,
The opening 95 has a substantially U-shaped cross section and is formed in the left-right direction as shown in FIG. 1 (the left-right direction in FIGS. 1 and 2 and the front-back direction toward the paper in FIG. 3).
Has been stretched to. The transport frame 87 is provided with a reinforcing member 97 extending in the front-rear direction (front and back directions toward the paper surface in FIG. 1, up-down direction in FIG. 2, left-right direction in FIG. 3). A plurality of supporting members 99 extending in the front-rear direction are provided on the lower plate 81 of the base frame 7 in the left-right direction at appropriate intervals. Also, the transport frame
A support bracket 101 integrally attached to the front and rear plates 91, 93 of the 87 extending in the left-right direction is supported by the front and rear plates 83, 85 of the base frame 7 so as to be movable in the left-right direction. There is.

With the above configuration, the transport frame 87 is the base frame 7
On the other hand, by moving in the left-right direction via the support member 99 and the support bracket 101, the transport frame 87 can be stored in the base frame 7. Further, the chip that has passed through the opening 75 of the base frame 7 passes through the opening 95 of the transport frame 87 and falls into the transport frame 87.

In order to convey the chips that have fallen into the conveyance frame 87 to the predetermined unloading section 103 on the left side, a chip conveyance device 105 is provided in the conveyance frame 87.

More specifically, a drive sprocket 107 is rotatably attached to the left end side in the transfer frame 87 via a rotational movement 109, and a driven sprocket 111 is attached to the right end side in the transfer frame 87 via a rotary shaft 113. It is attached rotatably. Then, the drive sprocket 107 and the driven sprocket 111.
A chain 115 is wound around. In order to drive the chain 115 in the clockwise direction (clockwise direction in FIG. 1), the support plate 11 forming a part of the transport frame 89.
The drive motor 119 is attached to the drive motor 7.
Reference numeral 9 is linked to the drive sprocket 107 via a timing belt (not shown) or the like. The above chain 115
Chain guides 121, 123 extending in the left-right direction are attached to the front and rear plates 91, 93 of the transfer frame 89 via attachment bolts 125 in order to guide them.

Referring to FIGS. 3 and 4, an appropriate number of the scrapers 127 extending in the front-rear direction are attached to the chain 115 via support brackets 129, and the scrapers 127 are made of an elastic material such as a leaf spring. The body 131 is provided so as to be inclined so that the left side, in other words, the front side when viewed from the conveying direction (the front side facing the paper surface in FIG. 3, the left side in FIG. 4) is low. It should be noted that the elastic body 131 is extended in the left-right direction, and it is desired to use the elastic body 131 as appropriate other than a leaf spring.

In addition, referring to FIG. 1, the base frame 7,
The cutting oil drops in addition to the chips through the openings 75 and 95 inside the transfer frame 87.
In order to send the cutting oil to the cutting oil tank 133 attached to the left side of the
Is provided. Further, in order to prevent the chips from passing through the holes 135, a wire mesh 139 is attached to the lower side of each hole 135.

The operation of the pump embodiment will be described based on the above configuration.

The work W is supported by the base frame 7, and the work W is fixed by the vise device 11. 1st drilling head 31, 2nd drilling head 47, 3rd drilling head
73 is appropriately operated to perform desired drilling on the work W from the upward, rightward, and leftward directions.

The chip produced by drilling is the base frame 7
Inside, dropped into the transfer frame 83 through the openings 75, 95,
It is located on the lower plate 89 of the carrier frame 87. And
The drive motor 119 is appropriately operated to drive the chain 115, and the chain 115 is driven to the left via the driven sprockets 107 and 111 to move the scraper 127 and the elastic body 131 to the left. As a result, the chips located on the lower plate 89 of the carrying frame 87 are scraped and carried to the carry-out section 103 in the left direction.

Under the above action, when the chip is sandwiched by the left side portion of the elastic body 131 (in other words, the front side portion when viewed from the transport direction in the elastic body 131) and the lower plate 89,
The left side of the elastic body 131 (front side when viewed from the conveying direction of the elastic body 131) tends to move upward, and the chipping of the chip is released, so that the scraper 127 moves and the chain 115.
It is comparatively less likely that the traveling of the chip will be hindered and the chip will not be properly scraped and conveyed.

According to the present embodiment, since the chips generated by the punching process are mechanically scraped and conveyed by appropriately operating the chip conveying device 105, compared to the case where the chips are manually conveyed. The work efficiency is good and the drilling can be performed smoothly. In addition, a left side portion of the elastic body 131 (in other words, a front side portion of the elastic body 131 when viewed from the transport direction),
Even when the chip is sandwiched between the lower plate 89 and the lower plate 89, it is possible to relatively prevent the chip from being conveyed.

Note that the present invention is not limited to the description of the above-described embodiment, and can be implemented in various other modes by making appropriate changes.

[Effects of the Invention] As will be understood from the above description of the embodiments, the present invention is, in short, a vise device capable of fixing a work (W) and an appropriate number of holes for drilling the work (W). A box-shaped base frame (7) supporting the dawn processing head is provided, and chain guides (121, 123) are provided on both sides of a box-shaped transfer frame (87) arranged in the base frame (7). The ends of a plurality of scrapers (127) are connected to a pair of endless chains (115) which are guided by (121, 123) and are connected to each other, and the elastic bodies (131) attached to the scrapers (127) are connected to each other. The tip side is provided slightly apart from the upper surface of the lower plate (89) in the transport frame (87), and the tip on the lower plate (89) is transported by the tip side of each elastic body (131). When the tip The tip side of each elastic body (131) is tilted so that the front side is lower when viewed from the carrying direction so that the tip moves between the lower plate (89) and the lower plate (89). This is the configuration provided.

As is apparent from the above structure, in the present invention, since the tip end of the elastic body 131 attached to the scraper 127 is slightly separated from the upper surface of the lower plate 89 in the transport frame 87, the elastic body 131 is attached to the lower plate 89. The chain 115 can be run lightly without rubbing the upper surface of the chain.

Further, the tip end side of the elastic body 131 is inclined so as to move upward when the chip is sandwiched between the elastic body 131 and the lower plate 89, so that the front side becomes lower when viewed from the transport direction. . Therefore, the elastic body 131 and the lower plate 89
Since there is a slight distance between the elastic body 131 and the lower plate 89, even if the chip tends to be sandwiched between the elastic body 131 and the lower plate 89, the tip of the elastic body 131 moves upward and the sandwiching is performed. It avoids the inclusion.

That is, according to the present invention, even when the chip tends to be caught between the elastic body 131 and the lower plate 89, the chip can be transferred without causing any problem. It is possible.
