Description

Technical Field

[0001] The utility model belongs to the technical field of cutting machines, and particularly relates to a body of a super-large-format laser cutting machine tool. Background Art

[0002] A laser cutting machine is a sheet metal processing device. It outputs a laser beam with a high energy density from a fiber laser, which is focused by a laser cutting head and irradiated on the surface of the sheet metal. The irradiated area of the sheet metal is instantly melted and vaporized, and then the position of the laser beam irradiation is moved through a numerical control mechanical system to achieve automatic cutting. The laser cutting machine can process various materials such as carbon steel, stainless steel, and aluminum. Due to its advantages such as fast cutting speed and high precision, it is widely used in the field of sheet metal processing. In recent years, with the increasingly strong market demand for sheet metal processing, large-format laser cutting machines with higher processing efficiency have emerged as the times require. The body provides support for all cutting-related activities and is one of the important components of a large-format laser cutting machine. Because its length can reach dozens of meters, its design, processing, and assembly are the key points and difficulties in the production of the entire machine tool.

[0003] At present, there are mainly two forms of the bodies of common large-format laser cutting machine tools on the market. One is an integral body. The body dozens of meters long is integrally welded and then clamped on a gantry milling machine for overall processing. This method requires a gantry milling machine that can process workpieces dozens of meters long. Gantry milling machines meeting this level of processing capacity are relatively rare, and the processing cost is very high. The other is a spliced body. The body is welded and machined in sections and then spliced together. Positioning pins are used for positioning at the joint surface and bolts are used for fixing. The operating space for driving the positioning pins in this way is limited. The positioning pins are applied at the joint of the left front body and the left rear body (which is also the right front body and the right rear body). This is the cutting area, and the step will have a negative impact on the cutting accuracy. Therefore, the installation is difficult. After the segmented bodies are spliced, an obvious step will be generated on the actual working plane, with low precision and non-adjustability. Content of the Utility Model

[0004] The purpose of the utility model is to provide a body of a super-large-format laser cutting machine tool to solve the problems existing in the background art.

[0005] To achieve the above object, the present utility model provides the following technical solutions: A laser cutting machine body with an extra-large format, including a front-end bed body, a left front bed body, a left rear bed body, a right front bed body, a right rear bed body, a tail support frame, a sealing plate, a Y-direction adjustment device, and floor bolts; both sides of the front-end bed body are respectively connected to the left front bed body and the right front bed body through positioning pins. After the left front bed body and the left rear bed body are aligned, they are connected together through an upper positioning plate and a side positioning plate. The connection method of the right front bed body and the right rear bed body is the same as that of the left front bed body and the left rear bed body. Both sides of the tail support frame are in contact connection with the left rear bed body and the right rear bed body. The sealing plate is fixed on the tail support frame. The Y-direction adjustment device and the floor bolts are respectively multiple and are fixed on the left front bed body, the left rear bed body, the right front bed body, and the right rear bed body.

[0006] Preferably, the Y-direction adjustment device includes a first connecting plate, a second connecting plate, a transverse adjustment bolt, and a long bolt. Among them, the first connecting plate is fixed to the ground through the long bolt, the second connecting plate is fixedly connected to the corresponding bed body, and after Y-direction adjustment between the first connecting plate and the second connecting plate, they are fastened together through bolts.

[0007] Preferably, there are at least two positioning pins.

[0008] The beneficial effects of the present utility model are:

[0009] This solution can reduce the installation difficulty during the splicing of the bed body. Through the design of segmented docking and adjustability, the overall accuracy of the bed body after docking is ensured, providing support for the high-precision cutting of subsequent workpieces. The positioning pins in this device are applied at the position of the front-end bed body, which is in the non-cutting area, and the cutting head will not reach this position, thus not affecting the cutting accuracy. The function of the positioning pins is to avoid the flare of the bed bodies on the left and right sides. BRIEF DESCRIPTION OF THE DRAWINGS

The first surface 2-1 and the fifth surface 3-1 are the actual joint surfaces of the two sections of the bed body. After the two surfaces are joined, the adjusting bolt 8-1 of the Y-direction adjusting device 8 is used to cause the segmented bed body to have a front-back displacement in the Y direction, and finally adjusted so that the second surface 2-2 and the sixth surface 3-2 are coplanar; by adjusting the floor feet 9, the segmented bed body is caused to have an up-down displacement in the Z direction, and finally adjusted so that the third surface 2-3 and the seventh surface 3-3 are coplanar.

[0026] Step 2: After the adjustment is completed, install the positioning plate and the side positioning plate to ensure that the two adjusted sections of the bed body do not displace in the Y direction and the Z direction. After the positioning plate is installed, tighten a set of bolts on the joint surface.

[0027] Step 3: The installation and adjustment of the right front bed body and the right rear bed body are the same as above.

[0028] Step 4: The Y-direction adjusting device is provided at multiple positions in the Y direction of the bed body and is fixed to the ground through anchor bolts.

[0029] Step 5: The ninth surface 1-1 and the tenth surface 1-2 of the front-end bed body 1 are machined surfaces, and are connected to the eleventh surface 2-4 of the left front bed body 2 and the twelfth surface 4-1 of the right front bed body 4 through the first positioning pin 13 and the second positioning pin 14 to ensure the matching accuracy of the two side bed bodies at the front part and prevent flaring deformation.

[0030] Step 6: The thirteenth surface 6-1 and the fourteenth surface 6-2 of the tail support frame 6 are finish-machined surfaces, and are in contact connection with the eighth surface 3-4 of the left rear bed body 3 and the fifteenth surface 5-1 of the right rear bed body 5 to ensure the matching accuracy of the two side bed bodies at the tail part and prevent flaring deformation.
