[0014] A laser welding device for hardware processing and a welding method thereof, comprising the following steps:

[0015] S1: When using this equipment, place the round tube and the top cover at the designated positions of the equipment respectively, and then start the motor to drive the three clamps to clamp and position the round tube;

[0016] S2: During the clamping process, the clamping block will drive the fixing rod to move together, and then the pressure rod will drive the limit block 2 and the fixing block to move downward together, so that the top of the top cover is flush with the top of the round tube;

[0017] S3: When the lower pressure rod is pressed downward, the air inside the sliding column is compressed, pushing the four positioning blocks away from each other, thereby positioning the top cover.

[0018] The present invention has the following beneficial effects:

[0019] (1) The two clamping blocks near the back of the present invention will drive the fixing rod to move together during the clamping process, and the fixing rod will drive the pressure plate to move, thereby compressing the air in the fixing shell and pushing the air in the fixing shell into the air duct. The air duct will pass the air into the fixing sleeve. The air passed into the fixing sleeve will push the pressure rod downward. The pressure rod will drive the second limit block and the fixing block to move downward together, and press the lower pressure rod downward through the fixing block until the bottom of the fixing block contacts the top of the top cover. As the pressure rod continues to move downward, the fixing block will press the top cover tightly and push the sliding column Push downward, and wait for the fixed block to move to the bottom of the leveling rod one or the leveling rod two and contact the top of the round tube. At this time, the top cover will move to the inside of the round tube, and its top will be flush with the top of the round tube. This design can make the top of the top cover flush with the top of the round tube and press the round tube at the same time through the downward pressure of the fixed block and the leveling rod one and the leveling rod two to judge the top position of the round tube. It is suitable for round tubes of different heights, thereby ensuring that the welding point is in the same horizontal plane during welding, ensuring the quality and aesthetics of the welding, and maintaining the round tube in a stable state during the welding process.

[0020] (2) The present invention starts a motor to drive the worm to rotate. The rotation of the worm will drive the rotating sleeve to rotate through the worm gear. The rotating sleeve will drive the fixed ring to rotate. The fixed ring will drive the friction block to rotate together. The friction block is tightly attached to the inner wall of the rotating ring under the action of spring 1, and drives the rotating ring to rotate through friction. The rotation of the rotating ring will drive the three clamping blocks to approach each other through the three connecting rods under the limiting action of limit block 1 and the workbench, and then the round tube is clamped and positioned by the three clamping blocks. This design can clamp and position round tubes of different radii through the clamping action of the three clamping blocks, thereby ensuring the accuracy of the position of the round tube and maintaining stability during the welding process, which helps to maintain the accuracy and consistency of the welded joints.

[0021] (3) The present invention welds the welding point between the round tube and the top cover through the welding arm. As the motor continues to run, the sliding column will continue to rotate. At this time, the round tube is in a state of being pressed by the leveling rod 1 and the leveling rod 2. Due to the effect of friction, the sliding column will drive the round tube to rotate together, thereby facilitating the welding of the welding point by the welding arm. Similarly, due to the effect of friction, the round tube will drive the leveling rod 1 and the leveling rod 2 to rotate, thereby driving the fixed block and the limit block 2 to rotate together. The rotation of the leveling rod 1 and the leveling rod 2 will drive the limit rods fixed on their tops to rotate respectively. When the limit rod rotates, due to the limiting effect of the limiting ring, before one side of the leveling rod 1 or the leveling rod 2 rotates to the welding point, the limit rod will drive the leveling rod 1 or the leveling rod 2 to slide toward the front to prevent the leveling rod 1 or the leveling rod 2 from blocking the welding point. This design can prevent the leveling rod 1 or the leveling rod 2 from blocking the welding point when the round tube rotates through the limiting effect of the limiting ring, thereby causing damage to the equipment and the workpiece.

[0022] (4) In the present invention, when the lower pressure rod is pressed downward, the lower pressure rod will compress spring three and the air inside the sliding column, pushing the four positioning blocks in a direction away from each other, and then before the top cover contacts the fixed block, the top cover is positioned by the four positioning blocks. The elastic coefficient of spring three is smaller than the elastic coefficient of spring two, so that when the lower pressure rod moves downward, the sliding column will not move downward under the action of spring three. This design can position the top cover and ensure that the top cover can be smoothly moved to the inside of the round tube without manual intervention, thereby improving the practicality and convenience of the equipment.

After the clamping blocks 114 complete the clamping of the circular tube 117, as the motor 103 continues to run, the fixed ring 108 will drive the friction block 110 to overcome the friction with the swivel 111 and continue to rotate, and the rotation of the rotating sleeve rod 106 will drive the storage table 107 and the sliding column 115 to rotate together.

[0044] For example 2, please refer to Figure 5 - Fig. 9The present invention is a laser welding device for hardware processing. On the basis of the first embodiment, two clamping blocks 114 near the back are fixedly connected to the sides of two fixed rods 201 that are away from each other, and the top of the fixed shell 203 is fixedly connected to an air guide tube 204. The air guide tube 204 is fixedly connected to a fixed sleeve 206 at one end away from the fixed shell 203. The outer surface of the fixed sleeve 206 is fixedly connected to a support frame 205. The bottom of the support frame 205 is fixedly connected to the top of the workbench 101. The inner wall of the fixed sleeve 206 is slidably connected with a pressure rod 207. The two clamping blocks 114 near the back will drive the fixed rod 201 to move together during the clamping process. The fixed rod 201 will drive the pressure plate 202 to move, thereby compressing the air in the fixed shell 203 and pushing the air in the fixed shell 203 into the air guide 204. The air guide 204 will pass the air into the fixed sleeve 206. The air passed into the fixed sleeve 206 will push the pressure rod 207 downward, and the pressure rod 207 will drive the limiting The second positioning block 302 moves downward together with the fixed block 303, and the lower pressing rod 401 is pressed downward by the fixed block 303 until the bottom of the fixed block 303 contacts the top of the top cover 118. As the pressing rod 207 continues to move downward, the fixed block 303 will press the top cover 118 and push the sliding column 115 downward. After the fixed block 303 moves to the bottom of the flush rod 1 304 or the flush rod 2 305 contacts the top of the round tube 117, the top cover 118 will move to the inside of the round tube 117, and its The top is flush with the top of the circular tube 117. This design can make the top of the top cover 118 flush with the top of the circular tube 117 through the downward pressure of the fixed block 303 and the top position of the circular tube 117 through the flush rod 1 304 and the flush rod 2 305. At the same time, the circular tube 117 can be pressed and it is suitable for circular tubes 117 of different heights, thereby ensuring that the welding points are in the same horizontal plane during welding, ensuring the quality and aesthetics of the welding, and maintaining the circular tube 117 in a stable state during the welding process.

[0045] The outer surface of the pressure rod 207 is fixedly connected to the inner wall of the limit ring 301, and the inner wall of the pressure rod 207 is rotatably connected to the outer surface of the limit block 2 302. The inner wall of the fixed block 303 is slidably connected with the leveling rod 1 304 and the leveling rod 2 305 respectively. The tops of the leveling rod 1 304 and the leveling rod 2 305 are fixedly connected with two limit rods 306 respectively. The outer surface of the limit rod 306 is slidably connected to the inner wall of the limit ring 301, and the welding arm 119 is used to weld the welding point between the round tube 117 and the top cover 118. As the motor 103 continues to run, the sliding column 115 will continue to rotate. At this time, the round tube 117 is in a state of being pressed by the leveling rod 1 304 and the leveling rod 2 305. Due to the effect of friction, the sliding column 115 will drive the round tube 117 to rotate together, thereby facilitating the welding of the welding arm 119 to weld the welding point. Due to the effect of friction, the round tube 117 will drive the leveling rod 1 304 and the leveling rod 2 305 to rotate, and then drive the fixed block 303 and the limit block 2 302 to rotate together. The rotation of the leveling rod 1 304 and the leveling rod 2 305 will drive the limit rod 306 fixed on the top of them to rotate. When the limit rod 306 rotates, due to the limiting effect of the limiting ring 301, before one side of the leveling rod 1 304 or the leveling rod 2 305 rotates to the welding position, the limit rod 306 will drive the leveling rod 1 304 or the leveling rod 2 305 to slide toward the front to prevent the leveling rod 1 304 or the leveling rod 2 305 from blocking the welding position. This design can prevent the leveling rod 1 304 or the leveling rod 2 305 from blocking the welding position when the round tube 117 rotates through the limiting effect of the limiting ring 301, thereby causing damage to the equipment and the workpiece.

[0046] The inner wall of the sliding column 115 is slidably connected to the outer surface of the lower pressure rod 401, the bottom of the spring three 402 is fixedly connected to the bottom of the inner wall of the sliding column 115, and the outer surface of the positioning block 403 is slidably connected to the inner wall of the sliding column 115. Four positioning blocks 403 are provided. When the lower pressure rod 401 is pressed downward, the lower pressure rod 401 will compress the spring three 402 and the air inside the sliding column 115, pushing the four positioning blocks 403 in the direction away from each other, and then before the top cover 118 contacts the fixed block 303, the top cover 118 is positioned by the four positioning blocks 403. The elastic coefficient of the spring three 402 is smaller than the elastic coefficient of the spring two 116, so that when the lower pressure rod 401 moves downward, the sliding column 115 will not move downward under the action of the spring three 402. This design can position the top cover 118, and ensure that the top cover 118 can be smoothly moved to the inside of the round tube 117 without manual intervention, thereby improving the practicability and convenience of the equipment.

[0047] The welding method of the laser welding equipment for hardware processing includes the following steps:

[0048] S1: When using the device, place the round tube 117 and the top cover 118 at the designated positions of the device respectively, and then start the motor 103 to drive the three clamping blocks 114 to clamp and position the round tube 117;

[0049] S2: During the clamping process, the clamping block 114 drives the fixing rod 201 to move together, and then the pressure rod 207 drives the second limit block 302 and the fixing block 303 to move downward together, so that the top of the top cover 118 is flush with the top of the round tube 117;

[0050] S3: When the pressing rod 401 is pressed downward, the air inside the sliding column 115 is compressed, and the four positioning blocks 403 are pushed away from each other, thereby positioning the top cover 118.

[0051] A specific application of this embodiment is:

[0052] When using the device, first move the device to the specified position, then place the round tube 117 and the top cover 118 at the specified positions of the device respectively, and then start the motor 103 to drive the worm 104 to rotate. The rotation of the worm 104 will drive the rotating sleeve rod 106 to rotate through the worm gear 105, and the rotating sleeve rod 106 will drive the fixed ring 108 to rotate, and the fixed ring 108 will drive the friction block 110 to rotate together. The friction block 110 is tightly attached to the inner wall of the rotating ring 111 under the action of the spring 109, and drives the rotating ring 111 to rotate through the friction force. The rotation of the rotating ring 111 will drive the three clamping blocks 114 to move between the limit block 113 and the The workbench 101 is limited to each other, and the three clamping blocks 114 are used to clamp and position the round tube 117. This design can clamp and position the round tube 117 of different radii through the clamping effect of the three clamping blocks 114, thereby ensuring the accuracy of the position of the round tube 117 and maintaining stability during the welding process, which helps to maintain the accuracy and consistency of the welded joint. After the clamping block 114 completes the clamping of the round tube 117, as the motor 103 continues to run, the fixed ring 108 will drive the friction block 110 to overcome the friction with the rotating ring 111 and continue to rotate, and the rotation of the rotating sleeve rod 106 will drive the storage table 107 and the sliding column 115 to rotate together;

[0053] The two clamping blocks 114 near the back will drive the fixing rod 201 to move during the clamping process, and the fixing rod 201 will drive the pressure plate 202 to move, thereby compressing the air in the fixing shell 203 and pushing the air in the fixing shell 203 into the air duct 204, and the air duct 204 will pass the air into the fixing sleeve 206, and the air passed into the fixing sleeve 206 will push the pressure rod 207 downward, and the pressure rod 207 will drive the limit block 202 and the fixing block 303 to move downward together, and press the lower pressure rod 401 downward through the fixing block 303 until the bottom of the fixing block 303 contacts the top of the top cover 118, and as the pressure rod 207 continues to move downward, the fixing block 303 will press the top cover 118 tightly and The sliding column 115 is pushed downward, and after the fixing block 303 moves to the bottom of the flush rod 1 304 or the flush rod 2 305 and contacts the top of the round tube 117, the top cover 118 will move to the inside of the round tube 117, and its top will be flush with the top of the round tube 117. This design can make the top of the top cover 118 flush with the top of the round tube 117 through the downward pressure of the fixing block 303 and the flush rod 1 304 and the flush rod 2 305. At the same time, the round tube 117 can be pressed tightly, and it is suitable for round tubes 117 of different heights, thereby ensuring that the welding point is in the same horizontal plane during welding, ensuring the quality and aesthetics of the welding, and maintaining the round tube 117 in a stable state during the welding process;

[0054] It should be noted that the radius of the fixing block 303 is smaller than the radius of the top cover 118 to prevent the fixing block 303 from blocking the welding point between the round tube 117 and the top cover 118 during welding. After the bottom of the flush rod 1 304 or the flush rod 2 305 contacts the top of the round tube 117, the pressing rod 207 can no longer move downward, and the air that continues to flow into the fixing sleeve 206 will be compressed, increasing the air pressure and not hindering the continued movement of the clamping block 114. In the above process, when the lower pressing rod 401 is pressed downward, the lower pressing rod 401 will compress the spring 3 402 and the air inside the sliding column 115. The four positioning blocks 403 are pushed away from each other by the air, and then the top cover 118 is positioned by the four positioning blocks 403 before the top cover 118 contacts the fixing block 303. The elastic coefficient of the spring three 402 is smaller than the elastic coefficient of the spring two 116, so that when the pressing rod 401 moves downward, the sliding column 115 will not move downward under the action of the spring three 402. This design can position the top cover 118 and ensure that the top cover 118 can be smoothly moved to the inside of the round tube 117 without manual intervention, thereby improving the practicality and convenience of the device;

[0055] After completing the above process, the motor 103 continues to run, and the welding arm 119 is used to weld the welding point between the round tube 117 and the top cover 118. As the motor 103 continues to run, the sliding column 115 will continue to rotate. At this time, the round tube 117 is in a state of being pressed by the leveling rod 1 304 and the leveling rod 2 305. Due to the effect of friction, the sliding column 115 will drive the round tube 117 to rotate together, thereby facilitating the welding of the welding point by the welding arm 119. Similarly, due to the effect of friction, the round tube 117 will drive the leveling rod 1 304 and the leveling rod 2 305 to rotate, thereby driving the fixed block 303 and the limit block 2 302 to rotate together. The rotation of the leveling rod 1 304 and the leveling rod 2 305 will drive the fixing blocks 303 and 302 fixed on their tops respectively. The limiting rod 306 at the top is rotated. When the limiting rod 306 rotates, due to the limiting effect of the limiting ring 301, before one side of the leveling rod 1 304 or the leveling rod 2 305 rotates to the welding position, the limiting rod 306 will drive the leveling rod 1 304 or the leveling rod 2 305 to slide toward the front to prevent the leveling rod 1 304 or the leveling rod 2 305 from blocking the welding position. This design can prevent the leveling rod 1 304 or the leveling rod 2 305 from blocking the welding position when the round tube 117 rotates through the limiting effect of the limiting ring 301, causing damage to the equipment and the workpiece. After welding is completed, the motor 103 is controlled to reset the various components of the equipment. The sliding column 115 will lift the workpiece after welding under the action of the spring 2 116, making it convenient for the staff to take out the material.
