Description

Technical Field

[0001] The utility model relates to a material fixing device for cutting by a laser cutting machine, and belongs to the technical field of material fixing devices for cutting by a laser cutting machine. Background Art

[0002] The laser cutting machine used in the related art mainly includes a machine table with a crossbeam provided on the machine table and a cutting head installed on the crossbeam. The plate to be cut is placed on the crossbeam, and the cutting head moves to cut the plate to complete the plate cutting work.

[0003] During the use of the existing positioning device for laser cutting processing, the staff uses a fixed plate to fix the four sides of the plate. Since some plates are thin and have poor flatness, the cutting size is different from the actual demand, which reduces the product quality. Secondly, during the use of the existing positioning device for laser cutting processing, the staff uses the naked eye to check the angle of the plate placement, and the manual determination of the angle is less accurate. The plate is still tilted, which is inconvenient to use and reduces the practicality of the device. In addition, during the actual processing process, the plate is freely placed flat on the cutting platform. Due to vibration or external force, the plate is easily displaced, resulting in low processing accuracy and even becoming waste.

[0004] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0005] In response to the deficiencies in the background technology, the utility model provides a material fixing device for laser cutting machine cutting, which can accurately locate the position of the plate placed on the laser cutting machine platform.

DETAILED DESCRIPTION

[0025] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, the utility model provides a material fixing device for cutting by a laser cutting machine, including a cutting platform 1, wherein support vertical plates 4 are arranged at equal intervals along the length direction of the cutting platform 1, and the plate 5 is placed on the support vertical plates 4. A movable crossbeam 2 is slidably installed on the cutting platform 1, and a laser cutting head 3 is installed on the movable crossbeam 2.

[0027] A first positioning member 6 and a second positioning member 7 are provided between the two adjacent supporting upright plates 4 at the front end. The first positioning member 6 and the second positioning member 7 are both composed of two vertically arranged baffles. The first positioning member 6 and the second positioning member 7 are arranged opposite to each other. When the plate 5 is placed on the supporting upright plates 4 of the cutting platform 1, the front end of the plate 5 presses against the transversely arranged baffles of the first positioning member 6 and the second positioning member 7, and the two sides of the plate 5 press against the longitudinally arranged baffles of the first positioning member 6 and the second positioning member 7.

[0028] A lower plate fixing part 8 is also provided between the two adjacent supporting vertical plates 4 at the front end. A multi-rod cylinder 10 is installed at the lower end of the lower plate fixing part 8. An upper pressure plate 11 is installed at the top end of the telescopic rod of the multi-rod cylinder 10. The upper pressure plate 11 is arranged at the upper end of the lower plate fixing part 8.

[0029] The first positioning member 6 is fixed to the inner side of the cutting platform 1 , and a sliding shaft 14 is transversely provided on the lower side between the two adjacent supporting upright plates 4 at the front end, and the second positioning member 7 is slidably installed on the sliding shaft 14 .

[0030] A lead screw 15 is further provided laterally on the lower side between the two adjacent support uprights 4 at the front end. The lead screw 15 is driven to rotate by a motor (not shown in the figure). The second positioning member 7 is threadedly engaged with the lead screw 15. The rotation of the lead screw 15 drives the second positioning member 7 to move closer to the first positioning member 6 to position the plate 5.

[0031] The lower plate fixing part 8 includes a top plate 801 and a rear side plate 802 and a front side plate 803 arranged vertically on both sides of the top plate 801. The front side plate 803 is connected to the push-pull cylinder 13. The distance between the rear side plate 802 and the front side plate 803 is smaller than the distance between the two supporting vertical plates 4. The push-pull cylinder 13 drives the lower plate fixing part 8 to slide back and forth by pulling the front side plate 803.

[0032] A guide shaft 9 is fixed on the rear side plate 802, and the guide shaft 9 is slidably installed on the rear support vertical plate 4. The guide shaft 9 guides the sliding of the fixing part 8 under the plate. The push-pull cylinder 13 is installed on the front support vertical plate 4, and the telescopic shaft of the push-pull cylinder 13 is connected to the front side plate 803.

[0033] A plurality of guide shafts 9 are fixed at equal intervals on the rear side plate 802 , and two push-pull cylinders 13 are connected to the front side plate 803 , and the two push-pull cylinders 13 operate simultaneously.

[0034] The upper surface of the top plate 801 is flush with the top end of the supporting upright plate 4 . A rubber plate 12 is provided on the upper surface of the top plate 801 and the lower surface of the upper pressing plate 11 .

[0035] The specific working principle of this utility model:

[0036] The plate 5 to be processed is placed on the cutting platform 1 through the plate loading mechanism, so that one corner of the plate 5 is pressed against the first positioning member 6, the front end of the plate 5 is pressed against the transverse baffle of the first positioning member 6, and the side of the plate 5 is pressed against the longitudinal baffle of the first positioning member 6. Then, the lead screw 15 is driven to rotate by the motor, and the second positioning member 7 is threadedly engaged with the lead screw 15. The rotation of the lead screw 15 drives the second positioning member 7 to move closer to the first positioning member 6 to position the plate 5.

[0037] After the plate 5 is positioned, the push-pull cylinder 13 pushes the lower fixing part 8 of the plate to slide backward until the rear side plate 802 is against the rear support vertical plate 4, and then, the telescopic rod of the multi-rod cylinder 10 contracts to press the upper pressure plate 11 downward, pressing the plate 5 between the upper pressure plate 11 and the lower fixing part 8 of the plate, so that the plate 5 is fixed and prevented from moving during the processing; then, the push-pull cylinder 13 pulls the lower fixing part 8 of the plate forward a short distance, so that the plate 5 is tightly pressed against the laterally arranged baffles of the first positioning part 6 and the second positioning part 7, preventing the gap between the plate 5 and the baffle from causing processing errors, thereby improving the processing accuracy.
