Description

working equipment

The present disclosure relates to a working device.

BACKGROUND ART Conventionally, work devices have been known that perform work while moving a work tool above the workpiece relative to the workpiece. For example, Patent Document 1 discloses a cutting device 100 as shown in FIG.

Specifically, the cutting device 100 includes a cutting torch 110 as a working tool, a support 120 that supports the cutting torch 110, and a lifting mechanism 130 that has a motor 131 and is interposed between the support 120 and a frame 140. . Further, the cutting device 100 includes a cart 150 that is attached to the support body 120 so as to be slidable in the vertical direction and runs on the workpiece 200.

A laser sensor 170 is attached to the support body 120 via a bracket 160, while a reflecting plate 180 that reflects the laser light from the laser sensor 170 is attached to the truck 150. The height of the cutting torch 110 from the surface of the workpiece 200 is maintained constant by the lifting mechanism 130 lifting and lowering the support body 120 in response to the signal from the laser sensor 170. In other words, the cutting torch 110 moves along the surface of the workpiece 200.

Japanese Patent Application Publication No. 6-71443

However, the cutting device 100 shown in FIG. 3 has a complicated structure for maintaining a constant height of the cutting torch 110 from the surface of the workpiece 200.

Therefore, an object of the present disclosure is to provide a work device that can maintain a constant height of a work tool from the surface of a workpiece with a simple structure.

The present disclosure includes at least one work tool disposed above a workpiece, a frame that moves relative to the workpiece in a lateral direction, and a frame that supports the at least one work tool and is slidable in the vertical direction. A working device is provided, comprising: at least one elevating table attached to the frame; and a roller, which is attached to the at least one elevating table and rolls on the surface of the workpiece.

According to the present disclosure, a working device is provided that can maintain a constant height of a working tool from the surface of a workpiece with a simple structure.

FIG. 1 is a schematic configuration diagram of a working device according to an embodiment. 2A and 2B are a cross-sectional side view and a front view of a portion of the working device. FIG. 2 is a front view of a conventional cutting device.

FIG. 1 shows a working machine 1 according to an embodiment. This work machine 1 performs work while moving at least one work tool 4 above the work 10 relative to the work 10.

Specifically, the work machine 1 includes at least one work tool 4 disposed above the work 10 and a frame 3 that moves laterally relative to the work 10. In this embodiment, the workpiece 10 is placed on a mounting table 11 fixed to the floor, and the frame 3 is moved. However, the frame 3 may be fixed to the floor and the mounting table 11 on which the workpiece 10 is placed may be moved.

In this embodiment, the workpiece 10 is plate-shaped, and is placed on the mounting table 11 in parallel to the horizontal direction. The frame 3 extends in a specific direction (left-right direction in FIG. 1) parallel to the surface (upper surface) of the workpiece 10. On the other hand, on both sides of the mounting table 11 in the specific direction, a pair of rails 21 extending in a direction perpendicular to the specific direction are fixed to the floor. A carriage 22 that is slidable along a rail 21 is attached to both ends of the frame 3. The frame 3 is moved in a direction perpendicular to the specific direction (ie, in the extending direction of the rail 21) by a drive machine including an electric motor and a linear motion mechanism.

In this embodiment, the work tool 4 is a cutting torch. That is, the work machine 1 performs cutting work. However, the work tool 4 may be a welding torch, and the work machine 1 may perform the welding work. Alternatively, when the work machine 1 performs non-destructive testing, the work tool 4 may be an inspection probe. Note that the work performed by the work machine 1 and the work tool 4 are not limited to these, and may be other types.

In this embodiment, the work machine 1 includes a plurality of work tools 4. These work tools 4 are each supported by a plurality of lifting platforms 5 (see FIGS. 2A and 2B). Specifically, as shown in FIGS. 2A and 2B, each lifting platform 5 has a plate shape that is parallel to the specific direction (the direction in which the frame 3 extends) and is long in the vertical direction. A working tool 4 corresponding to (the surface facing away from the frame 3) is fixed by a holder 41.

The plurality of elevating tables 5 are attached to the frame 3 in a state where they are lined up in the specific direction. The pitch of the lifting platform 5 in the specific direction may be equal or uneven.

Each lifting platform 5 is attached to the frame 3 so as to be slidable in the vertical direction. More specifically, a plate-shaped base 31 parallel to the elevator platform 5 is fixed to the front surface of the frame 3, and a pair of rails 51 arranged in the specific direction are fixed to this base 31. A carriage 52 that is slidable along a rail 51 is attached to the rear surface of the elevating table 5. In the illustrated example, two carriages 52 are provided for each rail 51, and the total number of carriages 52 is four.

Two rollers 7 that roll on the surface of the work 10 are attached to each lifting table 5 via supports 6. However, the number of rollers 7 may be one. The support 6 extends forward and backward from the lower part of the lifting platform 5, and then is bent downward. A roller 7 is rotatably attached to the tip of the downwardly bent portion of the support 6.

In the working machine 1 configured as described above, even if the surface of the workpiece 10 is uneven, the lifting platform 5 moves together with the rollers 7 following the unevenness. Therefore, the height of the working tool 4 from the surface of the workpiece 10 can be maintained constant with a simple structure in which the roller 7 is attached to the vertically slidable lifting table 5.

Furthermore, in this embodiment, a plurality of lifting platforms 5 are attached to the frame 3 in a state lined up in the specific direction, so that a plurality of flat bars of uniform width can be cut out at once.

Note that the present disclosure is not limited to the embodiments described above, and various modifications can be made without departing from the gist of the present disclosure.

(summary)
As a first aspect, the present disclosure includes at least one work tool disposed above a workpiece, a frame that moves relative to the workpiece in a lateral direction, and a frame that supports the at least one work tool in a vertical direction. A working device comprising: at least one lifting platform attached to the frame so as to be slidable; and a roller attached to the at least one lifting platform and rolling on the surface of the workpiece. provide.

According to the above configuration, even if there are irregularities on the surface of the workpiece, the lifting platform moves along with the rollers following the irregularities. Therefore, the height of the work tool from the surface of the workpiece can be maintained constant with a simple structure in which rollers are attached to a vertically slidable lifting platform.

As a second aspect, in the first aspect, the working tool may be a cutting torch or a welding torch. According to this configuration, cutting work or welding work can be performed.

As a third aspect, in the first or second aspect, the at least one work tool includes a plurality of work tools, and the at least one lifting platform includes a plurality of lifting tables each supporting the plurality of work tools. The workpiece is plate-shaped, the frame extends in a specific direction parallel to the surface of the workpiece, and the plurality of lifting platforms are attached to the frame in a state lined up in the specific direction. Good too. According to this configuration, when the work tool is a cutting torch, a plurality of flat bars having a uniform width can be cut out at once.
