Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a workbench of a large laser cutting machine. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting. When cutting large plates, the plates are first lifted to the machine tool of the laser cutting machine with an overhead crane, and then the plates are cut into several pieces. When the size of the workbench is large, it is not suitable for the staff to stand on the workbench to move the cut plates, because walking on the workbench may cause the support point on the workbench to move down. Therefore, an overhead crane is generally used to transfer the cut plates. However, the number of overhead cranes in a factory is limited, and the use of overhead cranes may be restricted. In addition, the efficiency of using overhead cranes to transfer plates one by one is low, so it is necessary to optimize the workbench of the large laser cutting machine. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1 , 2 As shown, the embodiment of the utility model proposes a workbench of a large laser cutting machine, including a main frame 1, a fixed frame 2, a plurality of first telescopic rods 3, a plurality of second telescopic rods 7 and a controller, wherein the main frame 1 is a horizontally arranged square frame structure, the size of the main frame 1 corresponds to the size of the plate 5 to be cut, and the cut plate 5 is placed on the main frame 1 and cut by the laser cutting machine. The fixed frame 2 is a frame structure horizontally arranged below the main frame 1, and the fixed frame 2 is fixedly connected to the ground. The first telescopic rod 3 is vertically and evenly arranged below the main frame 1, the bottom end of the first telescopic rod 3 is fixedly connected to the fixed frame 2, the top end of the first telescopic rod 3 is fixedly connected to the main frame 1, and the plurality of first telescopic rods 3 are synchronously extended and retracted, so that the main frame 1 is always in a horizontal state, avoiding the main frame 1 from tilting or being concave in the middle, which affects the cutting accuracy. The second telescopic rod 7 is vertically arranged and arranged in a rectangular array and covers the main frame 1, the fixed end of the second telescopic rod 7 is fixedly connected to the fixed frame 2, and the top end of the second telescopic rod 7 is provided with a roller 4. The first telescopic rod 3, the second telescopic rod 7 and the controller are electrically connected. When the plate 5 is cut, the plate 5 contacts the main frame 1. After the plate 5 is cut into several pieces by the laser cutting machine, the height of the second telescopic rod 7 gradually increases from one side to the other side and contacts the plate 5, so that the plate 5 near the side of the main frame 1 first slides to the outside of the main frame 1, and then the plate 5 slides to the outside of the main frame 1 in sequence. When the plate 5 is cut, the second telescopic rod 7 contracts to create a gap between the roller 4 and the plate 5, avoiding damage to the roller 4 caused by the laser during cutting, and also preventing the cut slag from being fixed on the roller 4 and affecting the rotation of the roller 4.

[0021] When all rollers 4 are located on an inclined surface, the second telescopic rod 7 supporting the rollers 4 on the upper side of the inclined surface needs a longer stroke to push the plate 5 upward from the main frame 1 to a sufficient distance. If the stroke is too long, failures and service life will be shortened. Therefore, when all rollers 4 need to adjust their height, the first telescopic rod 3 drives the main frame 1 to move downward a certain distance, and the rollers 4 originally adjacent to the side of the main frame 1 also move downward a certain distance, that is, when the angle of the inclined surface remains unchanged, the overall height of the rollers 4 shifts downward. The second telescopic rod 7 originally adjacent to the side of the main frame 1 had the smallest stroke, but now it has been changed to the second telescopic rod in the middle of the main frame 1 with the smallest stroke. This avoids the need for a second telescopic rod 7 with a larger stroke.

[0022] Preferably, a through hole is vertically penetrated on the main frame 1, and the fixed section of the second telescopic rod 7 is slidably matched with the through hole. The fixed section of the second telescopic rod 7 is slidably matched with the main frame 1, so that the entire workbench structure is stable, and the second telescopic rod 7 guides the main frame 1 to slide up and down.

[0023] Preferably, a plurality of detachable first support sheets 6 are vertically arranged on the top surface of the main frame 1. After a long period of laser cutting on the workbench, some slag will solidify on the part in contact with the plate 5, and subsequent processing will cause the plate 5 to be tilted and uneven, affecting the processing accuracy. Therefore, the first support sheets 6 need to be replaced regularly to avoid replacing the main frame 1 as a whole and save costs.

[0024] like Figure 2 , 3As shown, as a preference, a square rotating frame 13 is provided on the top surface of the main frame 1, and the first support sheet 6 is provided with a corresponding air-avoiding area of ​​the rotating frame 13, and the side of the rotating frame 13 can contact the main frame 1 without being blocked by the first support sheet 6. One side of the rotating frame 13 is rotatably connected to the side of the main frame 1, and a gap is provided between the other three sides of the rotating frame 13 and the side of the main frame 1, and a plurality of third telescopic rods 12 are arranged in parallel at the bottom of the rotating frame 13, one end of the third telescopic rod 12 is rotatably connected to the top surface of the main frame 1, and the other end of the third telescopic rod 12 is rotatably connected to the bottom of the rotating frame 13. A second support sheet is fixedly provided on the top surface of the rotating frame 13. An installation groove for installing the rotating frame 13 is provided on the top surface of the main frame 1. After the plate 5 is cut into the required several small pieces, due to the limitation of the cutting shape, a frame is still left, and the third telescopic rod 12 drives the rotating frame 13 to rotate, so that the remaining material slides to the outside of the main frame 1. The position where the residual material slides out from the rotating frame 13 and the plate 5 slides out from the roller 4 are not on the same side of the main frame 1, so that the staff can handle different materials. The distance from the connection point between the third telescopic rod 12 and the rotating frame 13 to the connection point between the rotating frame 13 and the main frame 1 is greater than half the width of the rotating frame 13, so that the third telescopic rod 12 can push the rotating frame 13 to rotate to an inclined state. When the main frame 1 is in a horizontal state, the third telescopic rod 12 is in an inclined state to avoid the third telescopic rod 12 being in a blind spot.

[0025] like Figure 2 As shown, as a preference, a guide plate 11 is provided on one side of the main frame 1, and the guide plate 11 is tilted downward away from the side of the main frame 1, and baffles 8 are fixedly provided on both sides of the guide plate 11, and the baffles 8 on both sides gradually approach each other from top to bottom. After the plate 5 is cut into several pieces in the horizontal and vertical directions, it is guided to one side of the main frame 1 by the roller 4, and then falls on the guide plate 11. When it slides down along the guide plate 11, it will gather to the middle due to the action of the baffle 8, which is convenient for the staff to transport. The position where the rotating frame 13 and the main frame 1 are rotatably connected and the guide plate 11 are respectively located on the adjacent two sides of the main frame 1.

[0026] Preferably, the roller 4 is made of metal. During laser cutting, waste residue with a high temperature may fall and contact the roller 4. The metal roller 4 can effectively resist the damage caused by the waste residue.

[0027] like Figure 4 As shown, preferably, the top edges of the first support sheet 6 and the second support sheet are wavy. The wave crests of the first support sheet 6 and the second support sheet are in contact with the plate 5. When the plate 5 is cut, the slag generated will fall downward if it does not contact the object. The wavy structure can reduce the area where the slag sticks, thereby reducing the frequency of replacing the first support sheet 6 and the second support sheet.

[0028] Preferably, the rotating frame 13 includes three rotating rods 9, a rotating shaft 10 and a connecting rod 14. The rotating shaft 10 is arranged on one side of the main frame 1 and is parallel to the side of the main frame 1. The rotating shaft 10 is rotatably connected to the main frame 1. The three rotating rods 9 are perpendicular to the rotating shaft 10. One end of the three rotating rods 9 is evenly fixedly connected to the rotating shaft 10. The connecting rod 14 is parallel to the rotating shaft 10. The connecting rod 14 is fixedly connected to one end of the rotating rod 9 away from the rotating shaft 10. The rotating rod 9 contacts the left, middle and right positions of the remaining plate 5. The three rotating rods 9 rotate synchronously, so that the remaining plate 5 slides toward one side of the main frame 1.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
