Description

Technical Field

[0001] The invention relates to the technical field of laser cutting equipment, and in particular to a laser cutting device for producing basketball stands. Background Art

[0002] Basketball stands are essential equipment for basketball courts, mainly including backboards and backboard pillars. In the manufacturing process of basketball stands, plates and profiles need to be cut into the shapes required for backboards and pillars. In order to ensure the cutting accuracy, laser cutting machines are usually used for cutting.

[0003] After searching, the patent with announcement number: CN221231781U, a laser cutting machine for producing basketball stands, includes an operating table and a laser cutter body, the top of the operating table is connected to a top frame, the bottom of the top frame is provided with a slideway that can be extended laterally, the bottom of the slideway is slidably connected to an L-shaped hanging plate, the laser cutter body is fixedly installed downward at the bottom of the L-shaped hanging plate, two spotlight strips are symmetrically arranged on both sides of the L-shaped hanging plate along the direction of the slide, and a line adjustment mechanism for synchronously adjusting the inclination angles of the two spotlight strips is installed on the L-shaped hanging plate.

[0004] Although the above patent can laser cut the workpiece for preparing the basketball stand by moving the laser cutter body, the above patent does not have the function of cleaning the molten waste slag. When the laser cutter body performs laser cutting on the workpiece, high temperature will be generated to melt the workpiece. At this time, the molten waste slag generated by the cutting is prone to sputtering, which can easily cause the molten waste slag to stick to the support of the operating table. After the molten waste slag cools, it will adhere to the support of the operating table, causing the plane of the supporting workpiece to be uneven, thereby affecting the flatness of the subsequent workpiece placement, causing the workpiece to tilt or be unstable, and directly affecting the quality and accuracy of the cutting.

The number of the connecting rods 6 is thirteen, and the thirteen connecting rods 6 are evenly spaced from left to right. Each connecting rod 6 is embedded with nine support blocks 7 evenly spaced along its axial direction. The support block 7 is used to support the workpiece. The top of the support block 7 is rotatably connected with a ball 71 for reducing the friction between the workpiece and the support block 7, so as to reduce the wear of the workpiece and the support block 7 during the process of pushing and picking up the workpiece, and extend the service life of the support block 7. The liquid collecting tank 2 is provided with a spray mechanism for spraying water on the support block 7.

[0032] See also Figure 3-Figure 5The liquid spraying mechanism includes a main pipe 81 connected to the outer wall of the rear side of the liquid collecting tank 2, and a row of branch pipes 82 are connected to the liquid collecting tank 2. The number of branch pipes 82 is thirteen, and the thirteen branch pipes 82 are evenly spaced from left to right. The thirteen branch pipes 82 correspond to the thirteen connecting rods 6 one by one. The branch pipes 82 are located at the lower side of the corresponding connecting rods 6. The front and rear ends of the branch pipes 82 extend to the outside of the liquid collecting tank 2. A rotating pipe 83 is rotatably inserted in each branch pipe 82. The outer wall of the rotating pipe 83 is tightly fitted with the inner wall of the branch pipe 82. The front and rear ends of the rotating pipe 83 extend to the outside of the liquid collecting tank 2. The rotating pipe 83 is connected to the main pipe 81 and is rotatably connected to the main pipe 81. A liquid outlet 86 is opened on the rotating pipe 83, and the liquid outlet 86 is located in the branch pipe 82. A branch pipe 83 is embedded in each support block 7. Tube 84, the shunt pipe 84 is connected to the branch pipe 82 located directly below it, and the top of the shunt pipe 84 is connected to a nozzle 85. The nozzles on the nozzle 85 are evenly distributed along the circumference of the nozzle 85 and extend to the outside of the support block 7 to achieve the effect of uniform water spraying along the circumference of the nozzle 85, and the nozzles on the nozzle 85 are set obliquely upward to achieve the goal of spraying water evenly and obliquely upward on the outer surface of the support block 7. The cross-sectional area of ​​the support block 7 gradually decreases from bottom to top, which is conducive to the water flow covering the outer surface of the support block 7 to form a water film, thereby ensuring that the molten waste generated during laser cutting is cleaned and diverted downward to the bottom of the inner side of the collecting tank 2 to achieve the effect of automatically cleaning the molten waste. The nozzle of the nozzle 85 is spaced a certain distance from the top of the support block 7, and the distance is between 0.5 cm and 1.5 cm to avoid spraying water directly on the workpiece.

[0033] See also Figure 3-Figure 5 A driving mechanism is provided on the front outer wall of the liquid collecting tank 2, and the driving mechanism is used to drive the rotating tube 83 to rotate for intermittent water spraying. The driving mechanism includes a row of slideways 91 connected to the front outer wall of the liquid collecting tank 2. The number of the slideways 91 is thirteen, and the thirteen slideways 91 are evenly spaced from left to right. The thirteen slideways 91 correspond to the thirteen rotating tubes 83 one by one. The slideways 91 are located at the lower side of the corresponding rotating tube 83. A rack frame 92 is slidably connected in each slideway 91, and a space between the bottom of the rack frame 92 and the inner bottom of the slideway 91 A spring Ⅰ93 is connected, and a gear 94 is connected to the front end of each rotating tube 83. The thirteen gears 94 correspond to the thirteen rack frames 92 one by one. The gear 94 is located in the corresponding rack frame 92 and meshes with the rack frame 92.

The middle part of the push block Ⅰ95 is a plane, and the left and right sides are inclined surfaces. The inclined surfaces on the left and right sides are inverted eight shapes. When the push block Ⅰ95 moves left and right, it can contact the rack frame 92 and squeeze the rack frame 92 downward through the inclined surface on the push block Ⅰ95.

[0034] First, connect the main pipe 81 to the infusion device, and then place the workpiece for processing the basketball stand on the support block 7. The three-axis mobile platform 4 can drive the laser head 5 to move in three axes, front and back, left and right, up and down, to perform laser cutting on the workpiece. While performing the laser cutting work, the infusion device is controlled to inject water into the main pipe 81, and the water then enters the rotating tube 83. Initially, the liquid outlet 86 on the rotating tube 83 is in a horizontal state and is not connected to the shunt tube 84, so that the water in the rotating tube 83 will not flow out. In the process of the three-axis moving platform 4 driving the laser head 5 to move left and right to cut the workpiece, it also drives the push block Ⅰ95 to move left and right. After the push block Ⅰ95 moves and contacts the rack frame 92, it continues to move, and squeezes the rack frame 92 downward through its upper inclined surface. The spring Ⅰ93 is compressed accordingly, and the rack frame 92 moves downward to push the gear 94 to drive the rotating tube 83 to rotate 90 degrees, so that the liquid outlet 86 on the rotating tube 83 rotates to a vertical state and is connected to the shunt tube 84. The water in the rotating tube 83 is then injected into the nozzle 85 through the shunt tube 84, and the nozzle 85 then sprays the water evenly and obliquely upward on the outer surface of the support block 7. In this way, the nozzle 85 located directly below the cutting area can spray water to clean the molten waste generated by laser cutting, while the other nozzles 85 do not spray water, avoiding the waste of water resources caused by excessive water spraying, thereby ensuring that the molten waste is automatically cleaned and avoiding the molten waste from adhering to the support block 7, causing the plane of the supporting workpiece to be uneven, so as to maintain the flatness of the subsequent workpiece placement, avoid the workpiece from tilting or being unstable, so as to improve the quality and accuracy of the cutting, and avoid the waste of water resources caused by excessive water spraying. When the push block I95 moves to be separated from the rack frame 92, under the reset action of the spring I93, the rack frame 92 can be pushed to move up and reset, and the rack frame 92 moves up to push the gear 94 to drive the rotating tube 83 to reverse 90 degrees, so that the liquid outlet 86 on the rotating tube 83 turns back to a horizontal state and is not connected to the diverter pipe 84, and the water in the rotating tube 83 stops flowing out, so as to achieve intermittent water spraying and reduce the waste of water resources.

The top of the piston rod Ⅱ109 is rotatably connected with a roller 1091 for reducing the friction between the push block Ⅱ1012 and the piston rod Ⅱ109, so as to reduce the wear of the push block Ⅱ1012 and the piston rod Ⅱ109 and extend the service life of the push block Ⅱ1012 and the piston rod Ⅱ109.

[0036] The two-way screw motor 102 is controlled to rotate to drive the two slide plates 101 to approach each other, and the clamping plates 103 on the front and rear sides are then approached to clamp and position the workpiece of the basketball stand to avoid displacement of the workpiece during laser cutting, thereby further improving the quality and accuracy of the cutting. In the process of the three-axis mobile platform 4 driving the laser head 5 to move left and right to cut the workpiece, it also drives the push block II 1012 to move left and right. The push block II 1012 moves and contacts the piston rod II 109 on the same side and then continues to move. The piston rod II 109 is pressed downward by its upper inclined surface, and the spring II 1010 is compressed accordingly.

Under the push of the liquid, the piston rod I105 is extended, and the lower part of the clamp 103 is pushed upward by the push rod 107, so that the upper part of the clamp 103 is swung downward and separated from the workpiece. In this way, the clamp 103 aligned with the laser head 5 can be swung and separated from the workpiece to avoid the laser head 5 and avoid hindering the laser cutting of the front and rear cutting paths of the workpiece by the laser head 5, while the remaining clamps 103 maintain a state of stably clamping the workpiece, thereby maintaining a stable clamping of the workpiece and avoiding hindering the normal laser cutting of the workpiece by the laser head 5.

The cloth cover 1184 is connected to the connecting shell 1183.

[0038] Through the cooperation of the cover body 114 and the shielding curtain 116, the laser cutting area can be effectively isolated to prevent the smoke and dust generated during laser cutting from floating around, thereby protecting the working environment and the health of workers. By controlling the operation of the vacuum pump 119, the smoke and dust generated during laser cutting can be sucked into the cloth cover 1184 through the suction pipe 115, the connecting ring 113, the air pipe 117 and the connecting shell 1183. The cloth cover 1184 can intercept foreign particles, and the gas passes through the cloth cover 1184 and is discharged to the outside through the vacuum hose 110. By connecting the vacuum pump 119 to an external pipeline, the gas can be discharged to a suitable location. When it is necessary to replace or clean the impurities in the cloth cover 1184, the box door 112 can be opened first, and then the connecting shell 1183 can be rotated to drive the internal threaded tube 1182 to rotate and disengage from the external threaded tube 1181, and then the cloth cover 1184 can be taken out from the box body 111 for replacement or cleaning. After the cloth cover 1184 is replaced or cleaned, the inner threaded tube 1182 is rotated back onto the outer threaded tube 1181 to re-lock the cloth cover 1184 in the box body 111 .

[0039] See also Fig.11A gathering mechanism for gathering the infusion hose 1011 is provided at the inner bottom of the liquid collecting tank 2, and the gathering mechanism includes two front and rear rows of storage boxes 121 connected to the inner bottom of the liquid collecting tank 2, and the number of storage boxes 121 in each row is twelve, and the twelve storage boxes 121 in each row are evenly spaced from left to right. A sliding block 122 that can move forward and backward is slidably connected in the storage box 121, and a fixed pulley 123 is rotatably connected to the top of the sliding block 122. A spring III 124 is connected between the sliding block 122 and the storage box 121. The two rows of storage boxes 121 correspond to the two rows of infusion hoses 1011 one by one, respectively. The infusion hose 1011 penetrates into the corresponding storage box 121, and the infusion hose 1011 bypasses the fixed pulley 123 in the corresponding storage box 121.

[0040] When the infusion hose 1011 follows the cylinder body I 104 to move in the direction away from the cylinder body II 108 on the same side, the infusion hose 1011 pulls the fixed pulley 123 and the sliding block 122 to move in the direction close to the cylinder body II 108 on the same side, and the spring III 124 is compressed accordingly. When the infusion hose 1011 follows the cylinder body I 104 to move in the direction close to the cylinder body II 108 on the same side, the fixed pulley 123 is relaxed. Under the resetting action of the spring III 124, the sliding block 122 can be pushed to move with the fixed pulley 123 in the direction away from the cylinder body II 108 on the same side, so as to tighten the infusion hose 1011. Therefore, through the cooperation of the fixed pulley 123 and the spring III 124, the infusion hose 1011 can be kept in a taut state at all times, thereby realizing the contraction of the infusion hose 1011 and preventing the infusion hose 1011 from being scattered, interfering with each other and affecting normal use.

It should be pointed out that, for those skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
