[0043] As Figures 1-3 shown, it shows a laser cutting male and female joint opening device in an embodiment of the present application, comprising:

[0044] A placing component 1 is arranged for collecting impurities generated during laser cutting, and the side surface of the placing component 1 is fixedly connected with a laser component 2, and the inner side of the placing component 1 is fixedly connected with a fixed plate 3;

[0045] A positioning component 4 is arranged for fixing the male and female joint, and the side surface of the positioning component 4 is fixedly connected with the inner side of the fixed plate 3;

[0046] Please refer to Figures 1-4 , the positioning component 4 includes two positioning racks 41, the side surface of the positioning rack 41 is slidingly connected with the inner side of the fixed plate 3, the upper and lower sides of the two positioning racks 41 are slidingly connected with a connecting shaft 42, the connecting shaft 42 is sleeved with a first spring 43, the two ends of the first spring 43 are fixedly connected with the side surface of the positioning rack 41, and the inner side of the positioning rack 41 is fixedly connected with a limiting mechanism 44;

[0047] The male and female joint is placed in the middle of the two positioning racks 41, the first spring 43 generates a pulling force, the two positioning racks 41 move relatively on the inner side of the fixed plate 3, and then drive the limiting mechanism 44 on the positioning rack 41 to clamp and limit the male and female joint placed between the two fixed plates 3,

[0048] For example, as Figures 1-5As shown, the limiting mechanism 44 includes a limiting rod 441, both ends of the limiting rod 441 are fixedly connected with the upper and lower sides of the positioning frame 41, the side of the limiting rod 441 is uniformly provided with a rubber block 442, the inner side of the rubber block 442 is fixedly connected with the side of the limiting rod 441, and the upper and lower sides of the limiting rod 441 are both threadedly connected with a limiting block 443;

[0049] When the two positioning frames 41 are pulled by the first spring 43, the two limiting rods 441 are relatively moved, so that the rubber blocks 442 at the front ends of the limiting rods 441 clamp and fix the male and female joints placed in the middle of the two positioning frames 41, the uniform and stable clamping force is provided by the elastic material of the rubber blocks 442, the displacement of the male and female joints during the machining process is avoided, the flexible feature of the rubber can effectively prevent the damage such as clamping marks and scratches on the surface of the joint, and the male and female joints with high surface precision requirements are especially suitable;

[0050] When the circular male and female joints are machined, the operator can rotate the limiting block 443 by threads, so that the limiting block 443 is flexibly moved on the limiting rod 441, the limiting blocks 443 on the rear two limiting rods 441 can be adjusted to be V-shaped, the V-shaped structure can accurately fit the outer contour of the circular male and female joint, not only the positioning accuracy of the circular workpiece is enhanced, but also the coaxial stability during the machining process is ensured, and the circular male and female joints with different diameter specifications can be adapted, the versatility and applicability of the equipment are improved, in this way, the limiting block 443 can stably clamp the circular male and female joint, and reliable guarantee is provided for the subsequent machining process;

[0051] As shown in the drawings, Figures 1-6 As shown, it shows that the placing component 1 in another embodiment of the application includes a workbench 11, the inner side of the workbench 11 is fixedly connected with the side of the fixed plate 3, the inner side of the workbench 11 is fixedly connected with a mesh plate 12, the inner side of the mesh plate 12 is rotatably connected with a rotating mechanism 13, both sides of the inner cavity of the workbench 11 are fixedly connected with a filtering mechanism 14, and the mesh plate 12 is arranged above the filtering mechanism 14;

[0052] Before the male and female joints are clamped and fixed, the filtering mechanism 14 can be opened in advance, the suction force generated when the mechanism operates can quickly form a negative pressure environment, the male and female joints are stably fixed between the two positioning frames 41 by the vacuum adsorption principle, the quick positioning work is carried out, so as to facilitate the clamping and fixing work of the male and female joints, and the clamping process is also simplified, and the feeding efficiency is improved;

[0053] When the laser cutting opening operation is performed on the male and female joints, the suction force generated by the filtering mechanism 14 continuously operates to suck the exhaust gas generated during the cutting process together with impurities into the workbench 11. The mesh plate 12 arranged in the middle of the inner cavity of the workbench 11 can intercept the solid impurities generated during processing and make them fall on the mesh plate 12. At the same time, the rotating mechanism 13 installed on the mesh plate 12 can continuously rotate to dynamically sweep the debris and impurities accumulated on the mesh plate 12, avoiding the accumulation of impurities at the same position on the mesh plate 12, preventing the accumulation of debris from affecting the air permeability of the mesh plate 12, and ensuring the air quality of the working environment and reducing the health threat to the operator.

[0054] For example, as shown in Figure 7 The rotating mechanism 13 includes a rotating block 131, the bottom of the rotating block 131 is rotatably connected to the top of the mesh plate 12, the bottom of the rotating block 131 is fixedly connected with a rotating blade 132, and the side surfaces of the rotating block 131 are uniformly provided with rotating rods 133. The number of rotating rods 133 is four, the four rotating rods 133 are uniformly arranged around the rotating block 131, and the side surfaces of the rotating rods 133 are fixedly connected to the inner side of the rotating block 131.

[0055] During the operation of the equipment, the suction force generated after the filtering mechanism 14 is started can drive the rotating blade 132 to drive the rotating block 131 to rotate on the top of the mesh plate 12, and the rotating block 131 further drives the rotating rod 133 to rotate synchronously to continuously sweep the impurities accumulated on the mesh plate 12, thereby achieving dynamic cleaning of the processing waste. Compared with the traditional static collection method, the problem of large accumulation of impurities on the top of the mesh plate 12 is avoided, the accumulation of impurities affecting the air permeability of the mesh plate 12 is prevented, the stability of the suction force of the filtering mechanism 14 is ensured, the exhaust gas collection efficiency is improved, the local blockage caused by the concentration of debris is avoided, and the frequency of manual cleaning is reduced.

[0056] For example, as shown in Figures 1-8 The filtering mechanism 14 includes a filter cylinder 141, the number of filter cylinders 141 is two, the two filter cylinders 141 are symmetrically arranged at the inner cavity of the workbench 11, the side surface of the filter cylinder 141 is fixedly connected to the inner side of the workbench 11, the side surface of the filter cylinder 141 is uniformly provided with air holes, the two sides of the inner cavity of the filter cylinder 141 are fixedly connected with exhaust mechanisms 142, one side of the exhaust mechanism 142 close to the end of the filter cylinder 141 is fixedly connected with a filter screen one 143, the other side of the exhaust mechanism 142 is fixedly connected with a filter screen two 144, and the middle part of the two filter screen two 144 is rotatably connected with a cleaning assembly 145.

[0057] After the exhaust mechanism 142 on both sides of the inner cavity of the filter cartridge 141 is started, the strong suction generated thereby can rapidly suck the waste gas and impurities generated during the laser cutting and punching process into the inner cavity of the workbench 11 through the air holes evenly arranged on the side surface of the filter cartridge 141, so that the waste gas and impurities are efficiently collected, the harmful gas and splashes are prevented from diffusing into the working environment, the health and safety of the operator are ensured, and the accumulation of pollutants in the workshop is reduced, so that the production environment is maintained clean;

[0058] Meanwhile, the suction generated by the exhaust mechanism 142 can also drive the cleaning assembly 145 to continuously rotate in the filter cartridge 141, so that the cleaning assembly 145 can clean the inner wall of the filter cartridge 141 in the rotating process, and the dust and impurities adsorbed on the wall of the filter cartridge 141 can be removed in time, so that the pollution of the inner wall of the filter cartridge 141 caused by the long-term passage of the waste gas is avoided, and the adsorption and ventilation performance of the filter cartridge 141 is improved;

[0059] Under the driving of the suction generated by the continuous operation of the exhaust mechanism 142, the waste gas entering the filter cartridge 141 passes through the filter screen one 143 and the filter screen two 144 in turn. The filter screen one 143 preliminarily intercepts the large-particle impurities in the waste gas through the structure with a large aperture. The filter screen two 144 further adsorbs the small dust, harmful particles and part of the gaseous pollutants in the waste gas through the fine mesh, so that multi-stage filtration and purification are realized. After the treatment of the double filter screens, the gas meeting the standard is discharged from the filter cartridge 141, which not only effectively reduces the pollutant content in the waste gas, but also reduces the pollution to the external atmospheric environment, so that the air in the workshop is clean, and a safe and healthy working environment is created for the operator;

[0060] For example, as shown in Figures 1-9 The cleaning assembly 145 includes a spiral blade 1451, both ends of the spiral blade 1451 are rotationally connected with the side surface of the filter screen two 144, both sides of the spiral blade 1451 are fixedly connected with a circular rod 1452, the other end of the circular rod 1452 is fixedly connected with a baffle 1453, the other side of the baffle 1453 is slidably connected with a slide rod 1454, the end of the slide rod 1454 away from the baffle 1453 is fixedly connected with a connecting plate 1455, the slide rod 1454 is sleeved with a second spring 1456, one end of the second spring 1456 is fixedly connected with the baffle 1453, the other end of the second spring 1456 is fixedly connected with the side surface of the connecting plate 1455, one side of the connecting plate 1455 is fixedly connected with a scraper 1457, and the other side of the connecting plate 1455 is rotationally connected with a cleaning cylinder 1458;

[0061] When the exhaust mechanism 142 operates to generate suction, the spiral blade 1451 is driven by the airflow to rotate between the two filter screens 144, the spiral blade 1451 drives the connecting plate 1455 to rotate synchronously through the round rod 1452, and then the scraper 1457 at the front end of the connecting plate 1455 is tightly attached to the inner side of the filter cylinder 141 to perform a circulating scraping operation, so as to timely remove the dust and impurities attached to the inner wall of the filter cylinder 141, effectively prevent the accumulation of pollutants from causing the air permeability of the filter cylinder 141 to decrease or be blocked, ensure the long-term stable operation of the waste gas treatment system, and reduce the equipment maintenance frequency.

[0062] During the scraping process of the scraper 1457, if the extrusion force of the impurities on the inner wall of the filter cylinder 141 exceeds the pre-tightening force of the second spring 1456, the second spring 1456 will be automatically stretched to drive the connecting plate 1455 and the scraper 1457 to slide along the slide rod 1454 in the baffle 1453, so as to avoid scratching and damaging the inner wall of the filter cylinder 141 due to excessive force, which not only ensures the cleaning effect, but also prolongs the service life of the filter cylinder 141.

[0063] The side of the connecting plate 1455 away from the scraper 1457 is rotationally connected with a cleaning cylinder 1458, which is used to wipe and clean the scraped area after the connecting plate 1455 is rotated by the round rod 1452 and the scraping action of the scraper 1457 is completed, so as to further improve the cleaning effect, remove the fine impurities remaining on the scraper 1457, ensure the cleanliness of the inner wall of the filter cylinder 141, and enhance the waste gas filtering efficiency.

[0064] Specific working process:

[0065] By placing the workpieces on the positioning components 4, a plurality of workpieces can be clamped at one time by using a clamp supporting multiple stations, so as to improve the batch processing efficiency.

[0066] During processing, the laser component 2 is turned on, an appropriate laser type is selected according to the material of the male and female joints, and the power and pulse frequency parameters are set, so as to perform laser cutting and opening operations on the workpieces clamped by the positioning components 4 on the fixed plate 3.

[0067] At the same time, the generated waste gas and debris during processing are collected and purified in real time by the matching waste gas and impurity collection and processing placing component 1, so as to ensure the cleanliness and safety of the processing environment.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
