Description

Technical Field

[0001] The present disclosure relates to a working device. Background Art

[0002] Conventionally, there is known a working device that performs work while moving a working tool relative to a workpiece above the workpiece. For example, Patent Document 1 discloses Figure 3 A cutting device 100 as shown.

[0003] Specifically, the cutting device 100 includes: a cutting torch 110 as a working tool; a support body 120 that supports the cutting torch 110; and a lifting mechanism 130 that is interposed between the support body 120 and a frame 140 and has a motor 131. In addition, the cutting device 100 includes: a trolley 150 that is mounted on the support body 120 in a manner that can slide in the up-down direction and travels on the workpiece 200.

[0004] A laser sensor 170 is mounted on the support body 120 via a bracket 160, and a reflector 180 for reflecting laser light from the laser sensor 170 is mounted on the carriage 150. The lifting mechanism 130 raises and lowers the support body 120 according to a signal from the laser sensor 170, thereby maintaining a constant height of the cutting torch 110 from the surface of the workpiece 200. In other words, the cutting torch 110 moves along the surface of the workpiece 200.

[0010] Figure 1 is a schematic structural diagram of a working device according to an embodiment; Figure 2 middle Figure 2 A and 2B are a sectional side view and a front view of a part of the working device; Figure 3 This is a front view of a conventional cutting device. DETAILED DESCRIPTION

[0011] Figure 1 1 shows a working machine 1 according to one embodiment. The working machine 1 performs work while moving at least one working tool 4 relative to the workpiece 10 above the workpiece 10 .

[0012] Specifically, the working machine 1 includes at least one working tool 4 disposed above the workpiece 10 and a frame 3 that moves laterally relative to the workpiece 10. In the present embodiment, the workpiece 10 is placed on a mounting table 11 fixed to the floor, and the frame 3 moves. However, the frame 3 may be fixed to the floor, and the mounting table 11 on which the workpiece 10 is placed may move.

[0013] In this embodiment, the workpiece 10 is plate-shaped and is placed on the mounting table 11 in a state parallel to the horizontal direction. The frame 3 is parallel to the surface (upper surface) of the workpiece 10 in a specific direction (in Figure 1 On the other hand, in the specific direction, on both sides of the mounting table 11, a pair of rails 21 extending in a direction orthogonal to the specific direction are fixed to the floor. A carriage 22 capable of sliding along the rails 21 is mounted at both ends of the frame 3. The frame 3 is moved in a direction orthogonal to the specific direction (i.e., the extending direction of the rails 21) by a driving machine including an electric motor and a direct-acting mechanism.

[0014] In this embodiment, the working tool 4 is a cutting torch. That is, the working machine 1 performs a cutting operation. However, the working tool 4 may be a welding torch and the working machine 1 may perform a welding operation. Alternatively, when the working machine 1 performs a non-destructive inspection, the working tool 4 may be an inspection probe. In addition, the operations performed by the working machine 1 and the working tool 4 are not limited to these, and may be other operations and working tools.

[0015] In this embodiment, the working machine 1 includes a plurality of working tools 4. These working tools 4 are provided by a plurality of lifting platforms 5 (see Figure 2A, 2B) respectively. Specifically, if Figure 2 As shown in A and 2B, each lifting platform 5 is parallel to the specific direction (the extension direction of the frame 3) and is a long plate in the vertical direction. In front of the lifting platform 5 (the surface facing the opposite side of the frame 3), a corresponding working tool 4 is fixed by a bracket 41.

[0016] The plurality of lifting platforms 5 are mounted on the frame 3 in a state of being arranged in the specific direction. The pitches of the lifting platforms 5 in the specific direction may be equal or unequal.

[0017] Each lifting platform 5 is mounted on the frame 3 in a manner that allows it to slide in the up-down direction. More specifically, a plate-shaped base 31 parallel to the lifting platform 5 is fixed to the front of the frame 3, and a pair of rails 51 arranged in the specific direction are fixed to the base 31. A slide 52 that can slide along the rail 51 is mounted on the rear of the lifting platform 5. In the example shown in the figure, two slides 52 are provided for each rail 51, and the total number of slides 52 is four.

[0018] Two rollers 7 are mounted on each lifting platform 5 via a support member 6 to rotate on the surface of the workpiece 10. However, the number of rollers 7 may be one. The support member 6 is bent downward after extending forward and backward from the lower part of the lifting platform 5. Then, the roller 7 is rotatably mounted on the tip end of the downwardly bent portion of the support member 6.

[0019] In the working machine 1 of the structure described above, even if there are irregularities on the surface of the workpiece 10, the lifting platform 5 moves along the irregularities together with the rollers 7. Therefore, the height of the working tool 4 from the surface of the workpiece 10 can be maintained constant by a simple structure in which the rollers 7 are installed on the lifting platform 5 that can slide in the up-down direction.

[0020] Furthermore, in the present embodiment, the plurality of lifting tables 5 are mounted on the frame 3 in a state of being arranged in the specific direction, so that a plurality of flat strips having a uniform width can be cut out at one time.

[0021] In addition, the present disclosure is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present disclosure.

[0022] (Summarize) As a first aspect, the present disclosure provides a working device comprising: at least one working tool, which is arranged above a workpiece; a frame, which moves laterally relative to the workpiece; at least one lifting platform, which supports the at least one working tool and is installed on the frame in a manner that allows it to slide in an up and down direction; and a roller, which is installed on the at least one lifting platform and rotates on the surface of the workpiece.

[0023] According to the above structure, even if there are bumps on the surface of the workpiece, the lifting platform moves along the bumps together with the rollers. Therefore, the height of the working tool from the surface of the workpiece can be maintained constant by a simple structure in which the rollers are installed on the lifting platform that can slide in the up-down direction.

[0024] As a second aspect, in the first aspect, the working tool may be a cutting torch or a welding torch. According to this structure, cutting work or welding work can be performed.

[0025] As a third aspect, in the first or second aspect, the at least one working tool may include a plurality of working tools, the at least one lifting platform may include a plurality of lifting platforms that respectively support the plurality of working tools, the workpiece may be plate-shaped, the frame may extend in a specific direction parallel to the surface of the workpiece, and the plurality of lifting platforms may be mounted on the frame in a state of being arranged in the specific direction. According to this structure, when the working tool is a cutting torch, a plurality of flat strips of uniform width may be cut out at one time.
