[0023] A slide plate 7 is arranged above the base shell 1, and an air injection pipe 8 is fixedly installed below the slide plate 7.

[0024] A filter box 5 is arranged above the slide plate 7, and a high-pressure air pump 6 is fixedly installed on one side of the filter box 5. The output end of the high-pressure air pump 6 is fixedly connected to the air inlet end of the jet pipe 8 through a pipeline, and the input end of the high-pressure air pump 6 extends to the interior of the filter box 5.

[0025] The utility model provides a laser hole-opening device for producing connecting ears of a push-pull mechanism of an elevator. By starting a high-pressure air pump 6, the high-pressure air pump 6 extracts gas from the inside of a filter box 5, and the extracted gas is transported to an air jet pipe 8 through a pipeline for ejection. The ejected gas is blown onto a plurality of placement rods 3 and a placement plate 2, and is used for blowing and cleaning impurities and dust remaining from the laser hole-opening in the gaps between the placement plate 2 and the plurality of placement rods 3. The impurities and dust cleaned by blowing and cleaning fall into the inside of the base shell 1 through a plurality of lower leakage holes 4, and effectively prevent impurities and dust remaining from the laser hole-opening from accumulating on the placement plate 2, thereby improving the flatness of the placement plate 2.

[0026] Furthermore, both sides of the base shell 1 are slidably connected to a gantry 9 via an electric slide rail 1, and the inner top wall of the gantry 9 is slidably connected to a laser engraving head 10 via an electric slide rail 2, and is used to produce laser holes for the connecting ears of the elevator push-pull mechanism.

[0027] Specifically, the electric slide rail 1 can drive the gantry 9 to move left and right, effectively adjusting the laser engraving head 10 to move left and right, and the electric slide rail 2 can drive the laser engraving head 10 to move forward and backward.

[0028] Furthermore, guide rails 11 are relatively fixedly installed on both sides of the inner wall of the gantry 9, and the guide rails 11 are slidingly connected to the slide plate 7. The inner top wall of the gantry 9 is located in front of the laser engraving head 10 and is also fixedly installed with an electric telescopic rod 12. The output end of the electric telescopic rod 12 is fixedly connected to the top of the slide plate 7.

[0029] Specifically, by starting the electric telescopic rod 12, the electric telescopic rod 12 pushes the slide plate 7 to move downward, and the linkage slide plate 7 slides on the guide rail 11 to adjust the air jet pipe 8 downward, effectively making the air jet pipe 8 closer to the placement plate 2, so that the air can be blown more cleanly during cleaning.

[0030] Furthermore, a collection funnel 13 is fixedly installed inside the base shell 1 just below the placement plate 2, and a plurality of support plates 14 are fixedly installed inside the base shell 1 between the placement plate 2 and the collection funnel 13, and are used to support and fix the placement plate 2. A draw groove 15 is opened on the front side of the base shell 1, and a collection box 16 is slidably connected to the inside of the draw groove 15.

[0031] Specifically, the collecting funnel 13 is used to collect the blown impurities and dust into the collection box 16. The collection box 16 is pulled and linked to slide in the extraction groove 15, so that the collection box 16 is pulled out from the base shell 1 through the extraction groove 15, so that the staff can clean the debris collected in the collection box 16.

[0034] The technical solution provided by this embodiment is: when the jet pipe 8 starts to extract the gas inside the filter box 5, the fume generated by laser welding is sucked into the interior of the filter box 5 together with the external gas from the gas collecting shell 20 through the air pipe. The fume and gas entering the filter box 5 are filtered through the gauze 19, filter cotton 18 and activated carbon filter 17, which are used to filter large and small particles of dust and odor in the fume and gas, effectively preventing the fume from causing harm to the workshop personnel. The filtered gas can be used again, thereby achieving the purpose of waste gas utilization and improving the use efficiency of the device.
