Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a laser cutting machine for producing automobile parts. Background Art

[0002] The laser cutting machine uses a high-power density laser beam to irradiate the material to be cut, causing the material to melt, vaporize, ablate or reach the ignition point quickly, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece;

[0003] Therefore, laser cutting machines are widely used in various processing fields. For example, some automobile parts will also be processed by laser cutting machines, such as the Chinese utility model patent disclosed by publication number CN218426255U: A laser cutting machine for automobile parts production, through the synchronous movement of the upper moving block and the lower moving block in the upper moving groove and the lower moving groove, so that the bearing strength can be strengthened through two moving points during the movement process, and the setting method of the supporting lifting component and the horizontal component is used to adjust the cutting height according to the different automobile parts, which improves the practicality of the cutting work to a certain extent, but in the process of cutting metal by laser cutting machine When processing metal sheets, since the thickness of metal sheets used for processing some automotive parts is relatively thin, a large amount of heat will be generated during the laser cutting process. Although the cutting speed is fast and the heat-affected area is small, when the metal sheet is thin, its thermal conductivity is better, and the heat is easily diffused to other areas of the sheet, causing these areas to deform due to heat. In addition, the structural strength and stability of the metal sheet itself are relatively low. After cutting a single area, the stress distribution of the sheet will change, especially in the absence of sufficient support. Other areas are more likely to deform due to stress release. Therefore, the parts subsequently cut out of the metal sheet will have non-compliant dimensions. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a laser cutting machine for automobile parts production, including an operating table 1, an X-direction driving mechanism 2 is fixedly installed in the operating table 1, two first side plates 3 are movably installed on the X-direction driving mechanism 2, a Y-direction driving mechanism 4 is fixedly installed between the two first side plates 3, two second side plates 5 are movably installed on the Y-direction driving mechanism 4, a Z-direction driving mechanism 6 is fixedly installed between the two second side plates 5, a laser generator carrier plate 7 is fixedly installed on one side of the Z-direction driving mechanism 6, and a laser generator carrier plate 7 is fixedly installed on one side of the laser generator carrier plate 7 8, and the X-axis driving mechanism 2, the Y-axis driving mechanism 4, the Z-axis driving mechanism 6, and the laser generator 8 are electrically connected to the external main controller through connecting lines respectively. The laser generator carrier plate 7 located on both sides of the laser generator 8 is provided with a resistance mechanism 9, and the resistance mechanism 9 includes two mounting plates 10 and two lifting plates 11. The mounting plate 10 is fixedly mounted on one side of the laser generator carrier plate 7, and the lifting plate 11 is movably mounted on one side of the corresponding mounting plate 10. A pressing plate 12 is also fixedly mounted on one side of the lifting plate 11, and a cover plate 13 is fixedly mounted on the pressing plate 12.

[0021] like Figure 2-Figure 3 As shown, a first fixing seat 14 is fixedly installed on one side of the mounting plate 10, and a second fixing seat 15 is fixedly installed on the mounting plate 10 located above the first fixing seat 14. A connecting bolt 16 is inserted between the first fixing seat 14 and the second fixing seat 15. Through the arrangement of the first fixing seat 14, the second fixing seat 15 and the connecting bolt 16, conditions for the vertical movable installation of the lifting plate 11 can be provided. A first connecting plate 17 is fixedly installed between the two lifting plates 11. Both ends of the first connecting plate 17 are respectively inserted on the corresponding connecting bolts 16, and the connecting bolts 16 between the first connecting plate 17 and the second fixing seat 15 are sleeved with a compression spring 18. The compression spring 18 applies pressure to the first connecting plate 17, which can ensure that when the Z-direction driving mechanism 6 drives the laser generator carrier plate 7 to move downward, it can prevent the pressing plate 12 from contacting the plate and limiting the Z-direction driving mechanism 6 from driving the laser generator carrier plate 7 to continue to move downward;

[0022] like Figure 2-Figure 4As shown, a second connecting plate 19 is fixedly installed on one side of the pressing plate 12, a card slot 20 is opened on the other side of the pressing plate 12, the second connecting plate 19 is fixedly installed on one side of the lifting plate 11, and a third connecting plate 21 is fixedly installed on one side of the cover plate 13, two support rods 22 are fixedly installed between the third connecting plate 21 and the cover plate 13, and a card block 23 is fixedly installed on the lower end of the cover plate 13.

Through the cooperation between the pressing plate 12, the ball 24 and the cover plate 13, it can be ensured that after the pressing plate 12 applies local pressure to the plate through the ball 24, it can be ensured that the laser generator 8 cooperates with the Y-axis driving mechanism 4 and the X-axis driving mechanism 2 to move and cut.

[0023] It should be noted that the utility model is a laser cutting machine for automobile parts production. When cutting a metal sheet, the metal sheet is first placed on an operating table 1, and then an external controller is used to control an X-direction drive mechanism 2, a Y-direction drive mechanism 4, a Z-direction drive mechanism 6 and a laser generator 8 to start cutting the sheet, and the Z-direction drive mechanism 6 drives the laser generator 8 to move downward by moving the laser generator carrier plate 7 downward;

[0024] Therefore, the laser generator carrier plate 7 drives the two mounting plates 10 to move downward synchronously at the same time, and because the two pressure plates 12 are located below the laser generator 8, the multiple balls 24 in the two pressure plates 12 will synchronously contact the metal plate, and then, the Z-direction driving mechanism 6 continues to drive the laser generator carrier plate 7 and the laser generator 8 to move downward a certain distance, so that the mounting plate 10 moves up and down on the connecting bolt 16 through the second fixing seat 15, and the second fixing seat 15 compresses the compression spring 18 toward the first connecting plate 17, thereby ensuring that the pressure plate 12 applies pressure to the metal plate with a certain pressure, and at the same time does not hinder the normal downward cutting operation of the laser generator 8, and multiple balls 24 roll on the metal plate, so that by applying pressure to the metal plate outside the cutting position, the expansion and contraction of the plate under the action of thermal stress can be suppressed, and the stress distribution of the plate can be adjusted to make the stress more uniform and reduce the degree of deformation.

[0025] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
