Description

Technical Field

[0002] Mechanical manufacturing is a process of converting various raw materials (such as metal materials, non-metallic materials) into mechanical parts or mechanical products with specific shapes, sizes and performances through a series of processing techniques (such as cutting, forging, casting, welding, etc.). It is mainly used in the fields of automobile manufacturing, aerospace and engineering machinery. In the mechanical manufacturing process, when it is necessary to weld two parts together by rotary welding, a rotary welding device is required. Common rotary welding devices include laser rotary welding devices, arc rotary welding devices, etc.

[0003] In the existing technology, the existing laser rotary welding device for mechanical manufacturing can weld two parts together and ensure the uniform thickness of the weld at the weld between the two parts to improve the welding quality during actual use, but it does not have the function of processing harmful substances and cooling the weld between the two parts after welding. When the laser rotary welding device is used to perform welding operation on the weld between the two parts, metal vapor, welding smoke, ozone and nitrogen oxide harmful substances will be generated during the welding process. At this time, the laser rotary welding device without the harmful substance processing function will not be able to process them, which will cause the harmful substances during welding to spread into the environment, which will affect the health of the workers and the air quality. At the same time, the laser rotary welding device without the cooling function cannot quickly and timely cool the weld between the two parts, which will cause cracks, deformation, etc. to appear at the weld between the two parts, which not only reduces the use effect of the rotary welding device, but also reduces the use efficiency of the rotary welding device.

[0044] The effect achieved by the entire mechanism is as follows: when it is necessary to use a laser welding device to weld two round tube parts together, first remove the first screw, and at the same time, use the hinge to rotate the second transparent plate 202 to a position where it cannot rotate, then connect the controller 117 and the welding host assembly 116 to the external power supply through the prepared power cord, then place one of the parts on one of the fixed plates 108 and adjust the position, then place the other part on the part with the adjusted position, and after completing the placement operation, also adjust the position, and then use the controller 117 to start the electric cylinder 103, at this time the started electric cylinder 103 will drive the connecting plate 104 to move, and the moving connecting plate 104 will be on the mounting frame connected to it. 105, drives the first motor 106 to move, and at the same time, the moving first motor 106 will also drive another fixed plate 108 to move with the cooperation of the connecting piece 107 and the fourth screw. When the bottom of the other fixed plate 108 contacts the top of another part and moves to a point where it cannot move, the controller 117 is directly used to pause the electric cylinder 103, and then the controller 117 is used to start the second motor 110. At this time, the started second motor 110 will use the cooperation of the placement slot 109 to drive the single-head screw rod 111 to rotate stably, and the rotating single-head screw rod 111 will drive the single-hole block 112 to move vertically under the action of the placement slot 109. At the same time, the moving single-hole block 112 will drive the laser welding gun 113 to move. Through the cooperation of the two first transparent plates 201, it is observed that when the laser head of the laser welding gun 113 reaches the welding point between the two parts, the second motor 110 is paused by the controller 117, and then the second transparent plate 202 is rotated back to its original position and fixed with the first screw, and then the first motor 106 is started by the controller 117. The started first motor 106 will drive the other fixed plate 108 to rotate with the cooperation of the workbench 101, the electric cylinder 103, the connecting plate 104, the connecting piece 107, the fourth screw and the mounting frame 105. At the same time, the rotating other fixed plate 108 will drive the two parts squeezed and fixed together to rotate with the cooperation of the workbench 101, the bearing and one of the fixed plates 108. When the two parts rotate at the same time, the welding host assembly 116 is opened, various parameters are set, and then the other rectangular plate 3 is removed, and then the bolts on the top of the box cover 209 (used to fix the box cover 209 and the processing box 207 together) are removed, and then the box cover 209 is moved upward, and then a proper amount of ice is placed in the position of the coil 210 in the processing box 207, and then the box cover 209 and the other rectangular plate 3 are reset to their original positions and fixed in turn, and finally the welding host assembly 116 is started. At this time, the started welding host assembly 116 will perform welding operations on the welding point between the two rotating parts with the cooperation of the composite wire 114 and the laser welding gun 113. When the welding point between the two parts completes a circle of welding operations,At this time, the welding host assembly 116 will be paused, that is, the laser welding gun 113 will stop welding the welding point between the two parts, and then the controller 117 will be used to start the fan 215, and then the started fan 215 will, with the cooperation of the second cylindrical hole 206, draw away the air inside the space composed of the workbench 101, the two first transparent plates 201 and the second transparent plate 202 (the metal vapor, welding smoke, ozone and nitrogen oxide harmful substances generated during the welding of parts will be dispersed inside this space, and the heat generated during the welding will also be dispersed inside this space), and then the drawn air will take away the harmful substances and heat together and enter the interior of the connecting pipe 208, and then be transported to the interior of the coil 210, and then in Under the action of ice cubes, the heat in the air carrying heat and harmful substances passing through the coil 210 is transferred away, and at the same time, the metal vapor will also be turned into metal particles due to cooling. Then the air will drive the harmful substances (except metal vapor) and metal particles into the space composed of the positive surface of the partition 211, the U-shaped frame 213, the side of the support plate 212 close to the partition 211, the processing box 207 and the box cover 209, and then pass through multiple filter screens 214 (activated carbon fiber boards) in sequence. When the air enters the interior of the intake pipe 217, the welding smoke and metal particles carried by the air have been filtered and retained by the multiple filter screens 214. At the same time, the ozone and nitrogen oxides carried in the air have also been filtered and retained by the multiple filter screens 214. 14 is adsorbed and disposed of, and then, with the cooperation of the started fan 215, the air entering the inside of the air inlet pipe 217 is transported to the inside of the air outlet pipe 218, and then transported to the inside of the mounting hole 102, and then transported to the inside of the first cylindrical hole 204, and then transported between the insides of the two round tube parts. When the air passes between the insides of the two round tube parts, the flowing air at this time will take away the heat of the welding point between the two round tube parts, and enter the inside of the L-shaped hole 203 together with the air, and then be transported to the inside of the space composed of the workbench 101, the two first transparent plates 201 and the second transparent plate 202, and a new cycle is carried out. In this way, the harmful substances generated when the round tube parts are welded can be disposed of, and at the same time The welding point between the two round tube parts after welding can be quickly and timely cooled down, that is, the welding quality is improved. When the welded round tube parts need to be removed from the rotary welding device, the above operation steps are repeated at this time, and the second transparent plate 202 is rotated until it cannot rotate. Then, the other fixed plate 108 is reset to its original position by using the cooperation of the controller 117, the electric cylinder 103 and the previous linkage components, and the welded round tube parts can be removed.
