DETAILED DESCRIPTION

[0017] The specific embodiments of the present application will be further described below in combination with the drawings.

[0018] As shown in the drawings, Figures 1-4 A sheet metal part laser cutting device, comprising a bed body 1 and a laser cutter 2, the bed body 1 is provided with a stroke assembly 3 for controlling the movement of the laser cutter 2, the inside of the bed body 1 is provided with two groups of support assemblies, the support assembly comprises a plurality of parallel sawtooth plates 4, and further comprises a plurality of bottom plates 5, the upper surface of the bottom plate 5 is provided with a plurality of vertical plates 6 at intervals, the vertical plate 6 is fixedly connected with the sawtooth plate 4, further comprising a horizontal plate 7 for connecting the plurality of bottom plates 5, further comprising an air cylinder 8, the air cylinder 8 is located in the inside of the bed body 1, the output end of the air cylinder 8 is fixedly connected with the horizontal plate 7, the lengths of the vertical plates 6 in the two support assemblies are different, and the sawtooth plates 4 in the two support assemblies are crosswise arranged.

[0019] The travel assembly 3 comprises X-axis travel, Y-axis travel and Z-axis travel, which are used to control the movement of the laser cutter 2 in X-axis, Y-axis and Z-axis respectively. The movement of the laser cutter 2 is controlled by the travel assembly 3, and the cutting of the sheet metal part is realized by controlling the start and stop of the laser cutter 2. The travel assembly 3 is a prior art, and its specific structure is not described here.

[0020] When the laser cutting of the sheet metal part is performed, the sheet metal part is first placed on the sawtooth plate 4 of one of the support assemblies. The travel assembly 3 and the laser cutter 2 perform the cutting of the sheet metal part according to the set program. When the position of the sheet metal part to be cut by the laser cutter 2 is directly above the sawtooth plate 4, in order to avoid the welding slag from being hung on the sawtooth plate 4 and to avoid the laser cutter 2 from cutting the sawtooth plate 4, all the air cylinders 8 in one of the support assemblies are controlled to start simultaneously. The air cylinders 8 in the support assembly push the sawtooth plate 4 in the support assembly to move upward by a certain distance, so that the sawtooth plate 4 in the support assembly can support the sheet metal part. After the sawtooth plate 4 in the support assembly has realized the support of the sheet metal part, the air cylinders 8 in the other support assembly are controlled to start, and the sawtooth plate 4 in the support assembly is moved downward by the air cylinders 8, so that the sawtooth plate 4 is away from the sheet metal part, thereby avoiding the welding slag from being hung on the sawtooth plate 4 below the sheet metal part during the cutting of the sheet metal part.

[0021] By continuously adjusting the height of the sawtooth plate 4 in the two support assemblies, the welding slag can be effectively avoided from being hung on the sawtooth plate 4. The coordinates of all the sawtooth plates 4 in the two support assemblies are recorded in the computer. When the moving track of the laser cutter 2 intersects with the sawtooth plate 4, the computer will comprehensively calculate according to the moving track coordinates of the laser cutter 2 and the coordinates of the sawtooth plate 4, so that the height of the sawtooth plate 4 in the corresponding support assembly is lowered before the laser cutter 2 moves to the position directly above the sawtooth plate 4 during the cutting.

[0022] Further, the inner bottom of the bed body 1 is slidably connected with a movable plate 9, the air cylinder 8 is arranged on the movable plate 9, one end of the bed body 1 is provided with a notch, one end of the movable plate 9 is provided with a baffle 10 for closing the notch of the bed body 1, both sides of the baffle 10 are respectively provided with side plates 11, both sides of the bed body 1 are respectively provided with limiting grooves 12, the side plates 11 can move in the limiting grooves 12, the side of the side plate 11 is provided with a sleeve 13, the inside of the sleeve 13 is slidably connected with an insertion plate 14, both sides of the stroke assembly 3 are respectively provided with vertical plates 15, the lower end of the vertical plate 15 is provided with a through groove 16 for the insertion plate 14 to pass through, after the device is used for a long time, a small amount of welding slag will still remain on the sawtooth plate 4, and a certain amount of welding slag will also accumulate at the bottom of the bed body 1, when the small amount of welding slag remaining on the sawtooth plate 4 and the welding slag in the bed body 1 need to be cleaned, first, the position of the vertical plate 15 is adjusted through the stroke assembly 3, so that the through groove 16 on the vertical plate 15 is aligned with the position of the insertion plate 14, then the insertion plate 14 is pulled out of the sleeve 13 and enters the through groove 16 of the vertical plate 15, then the vertical plate 15 is moved on the Y axis through the stroke assembly 3, thereby moving the side plate 11 in the limiting groove 12, then the side plate 11 moves the movable plate 9 and the two sets of supporting assemblies on the movable plate 9 out of the bed body 1 through the baffle 10, at this time, the welding slag falling on the movable plate 9 can be conveniently cleaned out, and the welding slag on the sawtooth plate 4 can also be conveniently cleaned, after the cleaning of the welding slag on the sawtooth plate 4 and the movable plate 9 is completed, the baffle 10, the movable plate 9 and the two supporting assemblies on the movable plate 9 are reset through the stroke assembly 3, after the reset is completed, the insertion plate 14 is pushed back into the sleeve 13, so that the insertion plate 14 is disconnected from the vertical plate 15, thereby not affecting the normal use of the stroke assembly 3.

[0023] The length of the insertion plate 14 is greater than the length of the sleeve 13, and the sleeve 13 has an anti-falling groove to prevent the insertion plate 14 from falling out of the sleeve 13.
