[0001] The invention belongs to the technical field of automobile parts welding, in particular to an automobile parts welding processing machine. Background Art

[0002] Auto parts welding machines play an important role and have broad application prospects in modern automobile manufacturing. The combination of laser welding technology and ultrasonic welding technology, as well as the application of automation and robotics technology, have greatly improved production efficiency and product quality, and promoted the development of the automobile manufacturing industry.

[0003] In the current existing technology, during the production welding process of the automobile body, a laser welding arm is usually used for welding. Since the automobile body is relatively wide, the extension distance of the laser welding arm has a certain range. There are still certain dead angles when using the laser welding arm for welding. Usually, the welding master needs to perform repair welding to complete the welding process of the automobile body. During the production process, the production efficiency is relatively low.

[0004] To this end, the present invention provides an automobile parts welding machine. Summary of the invention

[0007] The car shell is placed into the slide, and then the moving component drives the car shell to move through the slide. When the car shell is driven to move into the solid shell box, the solid shell component in the solid shell box fixes the car shell, and then two laser welding arms perform welding processing on the car shell in the solid shell box. When the welding processing is too large and the laser welding arm cannot extend, the rotating shell component in the rotating shell box drives the car shell in the solid shell box to rotate and adjust through the rotating wheel, and cooperates with the laser welding arm to perform welding processing on the car shell, thereby solving the problem in the prior art that the car shell is relatively wide, the extension distance of the laser welding arm has a certain range, and there are still certain dead angles when using the laser welding arm for welding. The setting of the solid shell component is to prevent the car shell from shaking due to stamping during welding, causing improper welding of the laser welding arm and affecting the welding processing operation.

At this point, the welding operation on the car shell is completed.

[0008] The cam is connected with the two levers with two guide wheels, and the two levers are connected with the two levers at the opposite ends of the two levers, and the two levers are connected with the two levers at the opposite ends of the levers, so that the levers can be moved along the vertical axis and the two levers can be moved along the vertical axis.

When the slide moves to one end of the moving rod 1, a joint assembly is provided between the moving rod 1 and the moving rod 2, so that the moving rod 1 and the moving rod 2 can be connected as a whole. When the moving motor drives the car shell into the solid shell box through the moving rod 1, the moving motor stops working, and the slide will move from the moving rod 1 to the moving rod 2, and then the solid shell assembly will fix the car shell in the slide from both sides of the slide, and then the rotating shell assembly cooperates with the laser welding arm to weld the car shell, and the moving motor drives the slide through the moving rod 1 to drive the car shell to move out of the solid shell box, thereby moving the car shell. By extending the length of the moving rod 1 and adding the number of slides, an assembly line processing can be formed, which can greatly improve the production efficiency in the manufacturing process.

[0009] Preferably, the bottom of the slide is rotatably connected to a plurality of rotating wheels, and the plurality of rotating wheels are slidably connected to the top of the guide groove plate, and three pads are fixedly installed on the inner wall of the slide, the tops of the pads on both sides are inclined, and the top of the other pad is flat, and the bottoms of the pads on both sides are provided with notches, and when the car shell is placed into the slide, the car shell is lifted by a lifting device, and then the car shell is lifted and placed on the pads entering the slide, and the car shell is placed in this way, and the stability of the car shell can be greatly guaranteed when the car shell moves, and the car shell can be prevented from slipping, colliding, etc. when moving, and when the slide moves, the rotating wheels at the bottom of the slide roll and slide on the guide groove plate, and the setting of the rotating wheels is to facilitate the movement of the slide.

When it is necessary to rotate and adjust the distance between the car shell and the two laser welding arms, the rotating shell assembly drives the solid shell box to rotate. When the rotating shell assembly rotates, the car shell is fixed in place by the solid shell assembly in the solid shell box and is placed in the solid shell box. The second moving rod in the shell box will also be relatively fixed by it, so when the rotating shell assembly rotates, the rotating shell assembly drives the convex shaft rod to slide out from the inner wall of the concave shaft rod through the second moving rod. When the rotating shell assembly drives the car body to rotate and the welding operation is completed, the rotating shell assembly drives the car body to reset, and the convex shaft rod will move back into the concave shaft rod. When the convex shaft rod moves in the concave shaft rod, the convex end of the convex shaft rod pushes the clamping shaft in the concave end of the concave shaft rod to move. When the clamping shaft moves, it squeezes the reset spring to slide on the positioning shaft. When the convex shaft rod is reset, When the locking shaft loses the squeezing thrust of the convex shaft rod, the locking shaft will slide out from the positioning shaft under the action of the restoring elastic force of the restoring spring, and one end of the locking shaft will be stuck in the circular opening, thereby connecting the concave shaft rod and the convex shaft rod, so that when the moving rod one rotates, the moving rod two can be driven to rotate together through the two, thereby realizing the moving of the slide out of the solid shell box. At the same time, through the setting of the dovetail assembly, when the rotating shell assembly rotates, the moving rod one and the moving rod two will not interfere with its rotation, thereby playing the role of disconnecting the moving rod one and the moving rod two.

Turn, and then the control button controls the two telescopic cylinders to operate. While the telescopic cylinders are operating, two of the gear rods are driven to move inward through the connecting rod, thereby driving the two solid shell arm blocks on one side to move inward. When the gear rods move inward, the other set of solid shell arm blocks can be driven to move inward synchronously through the meshing transmission of the gears. The two sets of solid shell arm blocks will move inward at the same time. When the four solid shell arm blocks touch the car shell, the telescopic cylinders are stopped from being driven. At this time, the four solid shell arm blocks complete the dead angle retention of the car shell, and play the role of fixing the car shell during welding.

[0013] Preferably, the inner walls of the two torque boxes are fixedly installed with arm moving motors, and the output ends of the two arm moving motors are installed with torque blocks. The two torque blocks are respectively slidably connected to the inner walls of the two torque boxes, and the two laser welding arms are respectively fixedly installed on the top of the two torque blocks. When the laser welding arms need to be adjusted, the torque blocks are driven to move in the torque box by the arm moving motor, and the laser welding arms placed on the top of the torque blocks will also be driven by the arm moving motor to move their positions. When the two laser welding arms move backward to adjust their positions, the rotating shell assembly drives the solid shell box to rotate on the top of the rotating shell box by driving the transfer wheel, so that when the laser welding arms adjust their positions, the rotating shell assembly drives the car body to also adjust, thereby coordinating the position adjustment of the two laser welding arms, thereby playing a role of coordinated adjustment.

[0014] Preferably, the shell rotating assembly also includes a rotation shaft, a rotation wheel is rotatably connected to the inner wall of the shell rotating box, the rotation shaft is fixedly installed on the top of the rotation wheel, the top end of the rotation shaft passes through the inner wall of the shell rotating box and is fixedly connected to the bottom of the solid shell box, one side of the two square blocks is fixedly installed with an L-shaped square rod, one end of the two L-shaped square rods is fixedly installed with a rotation rod, the teeth on the two rotation rods are meshed with the teeth on the rotation wheel, when the arm moving motor drives the laser welding arm to move through the square block, the square block synchronously drives the rotation rod to move through the L-shaped square rod, and the rotation rod will drive the rotation wheel to rotate when it moves, and the rotation wheel can drive the solid shell box to rotate on the top of the shell rotating box through the rotation shaft when it rotates, thereby rotating and adjusting the position of the car shell in the solid shell box, and adjusting the position of the car shell by moving the position of the laser welding arm, so that the two can cooperate in the adjustment operation, thereby adjusting the position of the laser welding arm and synchronously adjusting the position of the car shell.

By extending the length of the moving rod 1 and increasing the number of slides, an assembly line processing can be formed, which can greatly improve the production efficiency in the manufacturing process.

[0020] 3. The automobile parts welding processing machine described in the present invention drives the automobile shell to reset through the rotating shell assembly, and the convex shaft rod will move back into the concave shaft rod. When the convex shaft rod moves in the concave shaft rod, the convex end of the convex shaft rod pushes the clamping shaft in the concave end of the concave shaft rod to move. When the clamping shaft moves, the reset spring squeezes the positioning shaft to slide. When the convex shaft rod finishes resetting, the clamping shaft loses the squeezing thrust of the convex shaft rod, and the clamping shaft slides out of the positioning shaft under the action of the reset elastic force of the reset spring, and one end of the clamping shaft is stuck in the circular mouth, thereby connecting the concave shaft rod and the convex shaft rod, so that the moving rod one can drive the moving rod two to rotate together through the two when rotating, and the moving rod one and the moving rod two will not interfere with its rotation, thereby playing the role of disconnecting the moving rod one and the moving rod two.

At this time, the four solid shell arm blocks complete the dead angle fixation of the car body, and play the role of fixing the car body during welding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figures 1 to 12 As shown, an automobile parts welding processing machine described in an embodiment of the present invention comprises a bottom plate 1, a vertical plate 3 is symmetrically fixedly installed on the top of the bottom plate 1, a moving component assembly is arranged between the two vertical plates 3, the moving component assembly comprises a slide 9, the slide 9 is used to place the automobile shell, the moving component assembly is used to drive the automobile shell to move through the slide 9, a shell rotating box 6 is fixedly installed at the middle position on the top of the bottom plate 1, the top of the shell rotating box 6 is rotatably connected to a solid shell box 11, a solid shell assembly is arranged inside the solid shell box 11, the solid shell assembly is used to fix the automobile shell, and torque boxes 4 are symmetrically fixedly installed on both sides of the shell rotating box 6, laser welding arms 10 are arranged inside the two torque boxes 4, and two laser welding arms 10 are symmetrically arranged on both sides of the shell rotating box 6 and the solid shell box 11, a shell rotating component is arranged inside the shell rotating box 6, and the shell rotating component comprises a rotation wheel 404, and the shell rotating component is used to drive the automobile shell to rotate through the rotation wheel 404;

[0038] Since the car body is relatively wide, the extension distance of the laser welding arm 10 has a certain range, and there are still certain blind spots when the laser welding arm 10 is used for welding;

[0039] The car shell is placed into the slide 9, and then the moving component drives the car shell to move through the slide 9. When the car shell is driven to move into the solid shell box 11, the solid shell component in the solid shell box 11 fixes the car shell, and then two laser welding arms 10 weld the car shell in the solid shell box 11. When the position to be welded is too large and the laser welding arm 10 cannot extend, the rotating shell component in the rotating shell box 6 drives the car shell in the solid shell box 11 to rotate and adjust through the indexing wheel 404, and cooperates with the laser welding arm 10 to weld the car shell, thereby solving the problem in the prior art that the car shell is relatively wide and the laser welding arm 10 cannot reach the position where the car shell is welded. The extension distance of the optical welding arm 10 has a certain range. When using the laser welding arm 10 for welding, there will still be certain dead angle problems. The setting of the solid shell component is to prevent the car body from shaking due to stamping during welding, causing improper welding of the laser welding arm 10 and affecting the welding process. When the rotating shell component cooperates with the laser welding arm 10 to complete the welding operation of the car body, the rotating shell component is reset, the solid shell component releases the car body in the solid shell box 11, and the moving component drives the car body out of the solid shell box 11. At this point, the welding operation of the car body is completed. It should be noted here that this welding processing surface is the inner shell of the car body.

[0040] like Figures 2 to 4 The cam 7 is a kind of symmetrical and fixed device which is used for the lifting of the cam 7. The cam 7 has two movable parts, and the movable part 7 has two movable parts.

[0041] When the car shell is put into the slide 9, the moving motor 2 drives the moving rod 1 7 to rotate. When the moving rod 1 7 rotates, it can drive the slide 9 to move on the guide groove plate 5 through the thread transmission. When the slide 9 moves to one end of the moving rod 1 7, the moving rod 1 7 and the moving rod 2 71 are connected as a whole by the engagement assembly 8 provided between the moving rod 1 7 and the moving rod 2 71. When the moving motor 2 drives the car shell into the solid shell box 11 through the moving rod 1 7, the moving motor 2 stops working and the slide 9 will move from the moving rod 1 7 to the moving rod 2 71, and then the solid shell component will fix the car body in the slide 9 from both sides of the slide 9, and then the rotating shell component cooperates with the laser welding arm 10 to weld the car body, and the moving motor 2 drives the slide 9 through the moving rod 1 7 to drive the car body to move out of the solid shell box 11, so as to move the car body. By extending the length of the moving rod 1 7 and increasing the number of slides 9, an assembly line processing can be formed, which can greatly improve the production efficiency in the manufacturing process.

[0042] like Figures 4 to 6 As shown, the bottom of the slide 9 is rotatably connected to a plurality of rotating wheels 902, and the plurality of rotating wheels 902 are slidably connected to the top of the guide groove plate 5. Three pads 901 are fixedly installed on the inner wall of the slide 9. The tops of the pads 901 on both sides are inclined, and the top of the other pad 901 is flat. The bottoms of the pads 901 on both sides are provided with notches.

[0043] When placing the car shell into the slide 9, the car shell is lifted by the lifting device, and then the car shell is lifted and placed on the pad 901 entering the slide 9. Placing the car shell in this way can greatly ensure the stability of the car shell when the car shell moves, and prevent the car shell from slipping, colliding, etc. when moving. When the slide 9 moves, the rotating wheel 902 at the bottom of the slide 9 rolls and slides on the guide groove plate 5. The setting of the rotating wheel 902 is to facilitate the movement of the slide 9.

[0044] like Figures 10 to 12 As shown, the joint assembly 8 includes a notch shaft rod 801 and a convex shaft rod 802, one end of the notch shaft rod 801 is fixedly connected to one end of the moving piece rod 1 7, one end of the convex shaft rod 802 is fixedly connected to one end of the moving piece rod 2 71, the outer wall of the other end of the convex shaft rod 802 is slidably connected to the inner wall of the other end of the notch shaft rod 801, a plurality of positioning shafts 803 are symmetrically fixedly installed on the inner wall of the notch shaft rod 801, the outer walls of the plurality of positioning shafts 803 are slidably connected with a clamping shaft 804, a return spring 805 is arranged between one end of the plurality of clamping shafts 804 and the inner wall of the notch shaft rod 801, and the plurality of return springs 805 are respectively placed on the outside of the plurality of positioning shafts 803, the inner wall of the convex shaft rod 802 is symmetrically provided with a plurality of circular openings 806, and the plurality of clamping shafts 804 can be clamped with the inner walls of the plurality of circular openings 806 respectively;

[0045] When the slide 9 drives the car body through the joint assembly 8 into the solid shell box 11, the solid shell assembly in the solid shell box 11 fixes the car body, and then the two laser welding arms 10 weld the car body in the slide 9. When it is necessary to rotate and adjust the distance between the car body and the two laser welding arms 10, the rotating shell assembly drives the solid shell box 11 to rotate. When the rotating shell assembly rotates, the car body is fixed in the solid shell box 11 by the solid shell assembly and placed in the solid shell box 11. 1 will also be relatively fixed by it, so when the rotating shell assembly rotates, the rotating shell assembly drives the convex shaft rod 802 to slide out from the inner wall of the concave shaft rod 801 through the convex shaft rod 802. When the rotating shell assembly drives the automobile shell to rotate after the welding operation is completed, the rotating shell assembly drives the automobile shell to reset, and the convex shaft rod 802 will move back into the concave shaft rod 801. When the convex shaft rod 802 moves in the concave shaft rod 801, the convex end of the convex shaft rod 802 pushes the concave shaft rod 801. The card shaft 804 in the concave end moves, and the card shaft 804 squeezes the return spring 805 to slide on the positioning shaft 803 when moving. When the convex shaft rod 802 is reset, the card shaft 804 loses the squeezing thrust of the convex shaft rod 802, and the card shaft 804 slides out from the positioning shaft 803 under the action of the return elastic force of the return spring 805, and one end of the card shaft 804 is stuck in the circular opening 806, thereby connecting the concave shaft rod 801 and the convex shaft rod 802, so that the moving rod is When rotating, the two can drive the second moving rod 71 to rotate together, so as to move the slide 9 out of the solid shell box 11. At the same time, the setting of the joint assembly 8 can make the shell assembly rotate, and the moving rod 1 7 and the second moving rod 71 will not interfere with its rotation, so as to disconnect the moving rod 1 7 and the second moving rod 71. It should be noted that the length between the notched shaft rod 801 and the convex shaft rod 802 is smaller than the distance between the three sets of threaded openings opened inside the slide 9.

[0046] like Figures 1 to 5 As shown, a control button 14 is fixedly installed at the middle position of the inner wall of the solid shell box 11, and a straight-face groove 15 is opened on the inner wall of the solid shell box 11. The opening height of the straight-face groove 15 is flush with the inner groove height of the guide groove plate 5, and the multiple wheels 902 can be slidably connected with the inner wall of the straight-face groove 15;

[0047] When the slide 9 moves into the solid shell box 11, the rotating wheel 902 at the bottom of the slide 9 rolls in the straight surface groove 15 in the solid shell box 11. When the slide 9 moves to the specified position, the pad 901 in the slide 9 will squeeze the control button 14 in the solid shell box 11. When the control button 14 is squeezed, the operation of the moving motor 2 is stopped, and the solid shell component and the rotating shell component are controlled to operate, thereby playing a role in positioning control.

[0048] like Figures 4 to 8As shown, the solid shell assembly includes a solid shell arm block 1101, and there are four solid shell arm blocks 1101. The four solid shell arm blocks 1101 are symmetrically arranged at the four corners of the solid shell box 11, and the four solid shell arm blocks 1101 are all slidably connected to the inner wall of the solid shell box 11. A gear rod 1102 is fixedly installed on the inner side of the bottom end of the four solid shell arm blocks 1101, and a gear 1103 is rotatably connected to the inner wall of the solid shell box 11. The teeth on the four gear rods 1102 are respectively meshed with the teeth on the two gears 1103 in pairs, wherein a connecting rod 1104 is fixedly installed between the two gear rods 1102, and two telescopic cylinders 1105 are symmetrically fixedly installed on one side of the connecting rod 1104;

[0049] When the pad 901 contacts the control button 14, the control button 14 controls the moving motor 2 to stop running, and then the control button 14 controls the two telescopic cylinders 1105 to operate. While the telescopic cylinders 1105 are operating, two of the gear rods 1102 are driven to move inward through the connecting rod 1104, thereby driving the two solid shell arm blocks 1101 on one side to move inward. When the gear rod 1102 moves inward, the meshing transmission rotation of the gear 1103 can drive the other group of solid shell arm blocks 1101 to move inward synchronously, and the two groups of solid shell arm blocks 1101 will move inward at the same time. When the four solid shell arm blocks 1101 contact the car shell, the telescopic cylinders 1105 are stopped. At this time, the four solid shell arm blocks 1101 complete the dead angle retention of the car shell, which plays a role in fixing the car shell during welding.

[0050] like Figures 8 to 9 As shown, the inner walls of the two torque boxes 4 are fixedly installed with arm moving motors 401, and the output ends of the two arm moving motors 401 are installed with torque blocks 402. The two torque blocks 402 are respectively slidably connected to the inner walls of the two torque boxes 4, and the two laser welding arms 10 are respectively fixedly installed on the tops of the two torque blocks 402;

[0051] When the laser welding arm 10 needs to be adjusted, the arm moving motor 401 drives the moment block 402 to move in the moment box 4, and the laser welding arm 10 placed on the top of the moment block 402 will also be driven by the arm moving motor 401 to move its position. When the two laser welding arms 10 move back to adjust their positions, the rotating shell assembly drives the solid shell box 11 to rotate on the top of the rotating shell box 6 by driving the indexing wheel 404, so that when the laser welding arm 10 adjusts its position, the rotating shell assembly drives the car shell to be adjusted as well, thereby coordinating the position adjustment of the two laser welding arms 10 and playing a role in coordinated adjustment.

[0052] like Figures 7 to 9As shown, the rotating shell assembly also includes an indexing shaft 16, an indexing wheel 404 is rotatably connected to the inner wall of the rotating shell box 6, and the indexing shaft 16 is fixedly installed on the top of the indexing wheel 404. The top end of the indexing shaft 16 passes through the inner wall of the rotating shell box 6 and is fixedly connected to the bottom of the solid shell box 11. An L-shaped moment rod 403 is fixedly installed on one side of the two square blocks 402, and an indexing rod 407 is fixedly installed on one end of the two L-shaped moment rods 403. The teeth on the two indexing rods 407 are meshed with the teeth on the indexing wheel 404.

[0053] When the arm moving motor 401 drives the laser welding arm 10 to move through the moment block 402, the moment block 402 synchronously drives the indexing rod 407 to move through the L-shaped moment rod 403. The indexing rod 407 will drive the indexing wheel 404 to rotate when it moves. When the indexing wheel 404 rotates, it can drive the solid shell box 11 to be indexed on the top of the shell rotating box 6 through the indexing shaft 16, so as to adjust the position of the car shell in the solid shell box 11. By moving the position of the laser welding arm 10, the position of the car shell is adjusted, and the two can cooperate in the adjustment operation, so as to adjust the position of the laser welding arm 10 and the position of the car shell at the same time.

[0054] like Figures 7 to 9 As shown, a plate shifting rod 405 is fixedly installed on one side of the two L-shaped rectangular rods 403, and rectangular grooves 406 are symmetrically opened on the inner wall of the bottom plate 1. The inner walls of the two rectangular grooves 406 are slidably connected with a fitting plate 12, and one side of the two fitting plates 12 is respectively slidably connected to one side of the two guide groove plates 5, and the inner groove height of the two fitting plates 12 is the same as the inner groove height of the two guide groove plates 5, and one end of the two plate shifting rods 405 is respectively fixedly connected to the bottom of the two fitting plates 12;

[0055] When the arm moving motor 401 drives the transfer rod 407 to move through the L-shaped moment rod 403, the L-shaped moment rod 403 drives the engaging plate 12 to slide in the moment groove 406 through the plate shifting rod 405, so that the engaging plate 12 moves out from one end of the guide groove plate 5, to prevent the setting of the engaging plate 12 from affecting the transfer of the solid shell box 11 when the solid shell box 11 is rotated and adjusted at the top of the rotating shell box 6.

[0056] like Figures 2 to 9 As shown, the outer wall of the solid shell box 11 is symmetrically fixed with inclined groove plates 13, and the two inclined groove plates 13 can respectively fit with the inner walls of the two fitting plates 12, and the two can form a complete slide plate when they fit together;

[0057] When the operation is completed, the arm moving motor 401 drives the laser welding arm 10 to reset, the solid shell box 11 will rotate and reset on the top of the rotating shell box 6, and the matching plate 12 will slide and reset in the rectangular groove 406. When the solid shell box 11 is reset, the matching plate 12 moves to its original position and forms a complete slide plate with the inclined groove plate 13, which is convenient for the next slide 9 to move into the solid shell box 11, and plays the role of receiving the movement of the slide 9.

[0058] Working principle: The car shell is placed into the slide 9, and then the moving component drives the car shell to move through the slide 9. When the car shell is driven to move into the solid shell box 11, the solid shell component in the solid shell box 11 fixes the car shell, and then two laser welding arms 10 perform welding processing on the car shell in the solid shell box 11. When the welding process is too large and the laser welding arm 10 cannot extend, the rotating shell component in the rotating shell box 6 drives the car shell in the solid shell box 11 to rotate and adjust through the indexing wheel 404, and cooperates with the laser welding arm 10 to perform welding processing on the car shell, thereby solving the existing technology In the process, the car shell is relatively wide, and the extension distance of the laser welding arm 10 has a certain range. When the laser welding arm 10 is used for welding, there will still be a certain dead angle problem. The setting of the solid shell component is to prevent the car shell from shaking due to stamping during welding, causing improper welding of the laser welding arm 10 and affecting the welding process. When the rotating shell component cooperates with the laser welding arm 10 to complete the welding operation of the car shell, the rotating shell component is reset, the solid shell component releases the car shell in the solid shell box 11, and the moving component drives the car shell to move out of the solid shell box 11. At this point, the welding operation of the car shell is completed;

[0059] When the car shell is put into the slide 9, the moving motor 2 drives the moving rod 1 7 to rotate. When the moving rod 1 7 rotates, it can drive the slide 9 to move on the guide groove plate 5 through the thread transmission. When the slide 9 moves to one end of the moving rod 1 7, the moving rod 1 7 and the moving rod 2 71 are connected as a whole by the engagement assembly 8 provided between the moving rod 1 7 and the moving rod 2 71. When the moving motor 2 drives the car shell into the solid shell box 11 through the moving rod 1 7, the moving motor 2 stops working and the slide 9 will move from the moving rod 1 7 to the moving rod 2 71, and then the solid shell assembly will fix the car body in the slide 9 from both sides of the slide 9, and then the rotating shell assembly cooperates with the laser welding arm 10 to weld the car body, and the moving motor 2 drives the slide 9 through the moving rod 1 7 to drive the car body to move out of the solid shell box 11, playing the role of moving the car body. By extending the length of the moving rod 1 7 and adding the number of slides 9, an assembly line process can be formed, which can greatly improve the production efficiency in the manufacturing process;

[0060] When placing the car shell into the slide 9, the car shell is lifted by the lifting device, and then the car shell is lifted and placed on the pad 901 entering the slide 9. By placing the car shell in this way, the stability of the car shell can be greatly guaranteed when the car shell moves, and the car shell can be prevented from slipping, colliding, etc. when moving. When the slide 9 moves, the rotating wheel 902 at the bottom of the slide 9 rolls and slides on the guide groove plate 5. The setting of the rotating wheel 902 is to facilitate the movement of the slide 9;

[0061] When the slide 9 drives the car shell through the joint assembly 8 and enters the solid shell box 11, the solid shell assembly in the solid shell box 11 fixes the car shell, and then the two laser welding arms 10 weld the car shell in the slide 9. When it is necessary to rotate and adjust the distance between the car shell and the two laser welding arms 10, the rotating shell assembly drives the solid shell box 11 to rotate. When the rotating shell assembly rotates, since the car shell is fixed by the solid shell assembly in the solid shell box 11, the moving rod 2 71 placed in the solid shell box 11 will also be relatively fixed by it. Therefore, when the rotating shell assembly rotates, the rotating shell assembly drives the convex shaft rod 802 to slide out from the inner wall of the concave shaft rod 801 through the moving rod 2 71. When the rotating shell assembly drives the car shell to rotate and the welding operation is completed, the rotating shell assembly drives the car shell to reset, and the convex shaft rod 802 will move back into the concave shaft rod 801. When the convex shaft rod 802 is in the concave shaft rod 80 When the cam 802 is moved in the inner part, the convex end of the convex shaft rod 802 pushes the clamping shaft 804 in the concave end of the concave shaft rod 801 to move. When the clamping shaft 804 moves, the reset spring 805 is squeezed to slide on the positioning shaft 803. When the convex shaft rod 802 is reset, the clamping shaft 804 loses the squeezing thrust of the convex shaft rod 802. Under the action of the reset elastic force of the reset spring 805, the clamping shaft 804 will slide out of the positioning shaft 803, and one end of the clamping shaft 804 will be stuck in the circular opening 806, so that the concave shaft rod 801 and the convex shaft rod 802 are connected, so that the moving piece rod 1 7 can drive the moving piece rod 2 71 to rotate together when the moving piece rod 1 rotates, thereby realizing the moving of the slide 9 from the inside of the solid shell box 11. At the same time, the setting of the joint assembly 8 can make the moving piece rod 1 7 and the moving piece rod 2 71 not interfere with its rotation when the rotating shell assembly rotates, so as to disconnect the moving piece rod 1 7 and the moving piece rod 2 71.

[0062] When the slide 9 moves into the solid shell box 11, the rotating wheel 902 at the bottom of the slide 9 rolls in the straight surface groove 15 in the solid shell box 11. When the slide 9 moves to the specified position, the pad 901 in the slide 9 will squeeze the control button 14 in the solid shell box 11. When the control button 14 is squeezed, the operation of the moving motor 2 is stopped, and the solid shell component and the rotating shell component are controlled to operate, which plays a role in positioning control.

[0063] When the pad 901 contacts the control button 14, the control button 14 controls the moving motor 2 to stop running, and then the control button 14 controls the two telescopic cylinders 1105 to operate. While the telescopic cylinders 1105 are operating, two of the gear rods 1102 are driven to move inwards through the connecting rod 1104, thereby driving the two solid shell arm blocks 1101 on one side to move inwards. When the gear rods 1102 move inwards, the meshing transmission rotation of the gears 1103 can drive the other group of solid shell arm blocks 1101 to move inwards synchronously, and the two groups of solid shell arm blocks 1101 will move inwards at the same time. When the four solid shell arm blocks 1101 contact the car shell, the telescopic cylinders 1105 are stopped. At this time, the four solid shell arm blocks 1101 complete the dead angle fixation of the car shell, which plays a role in fixing the car shell during welding;

[0064] When the laser welding arm 10 needs to be adjusted, the arm moving motor 401 drives the moment block 402 to move in the moment box 4, and the laser welding arm 10 placed on the top of the moment block 402 will also be driven by the arm moving motor 401 to move its position. When the two laser welding arms 10 move back to adjust their positions, the shell rotating assembly drives the solid shell box 11 to rotate on the top of the shell rotating box 6 by driving the indexing wheel 404, so that when the laser welding arm 10 adjusts its position, the shell rotating assembly drives the car body to adjust as well, thereby coordinating the position adjustment of the two laser welding arms 10, playing a role of coordinated adjustment;

[0065] When the arm moving motor 401 drives the laser welding arm 10 to move through the moment block 402, the moment block 402 synchronously drives the indexing rod 407 to move through the L-shaped moment rod 403, and the indexing rod 407 drives the indexing wheel 404 to rotate when moving, and the indexing wheel 404 drives the solid shell box 11 to index on the top of the shell rotating box 6 through the indexing shaft 16 when rotating, so as to index and adjust the position of the car shell in the solid shell box 11, and adjust the position of the car shell by moving the position of the laser welding arm 10, so that the two can cooperate in the adjustment operation, so as to adjust the position of the laser welding arm 10 and the position of the car shell at the same time;

[0066] When the arm moving motor 401 drives the indexing rod 407 to move through the L-shaped moment rod 403, the L-shaped moment rod 403 drives the fitting plate 12 to slide in the moment groove 406 through the plate moving rod 405, so that the fitting plate 12 moves out from one end of the guide groove plate 5, so as to prevent the setting of the fitting plate 12 from affecting the indexing of the solid shell box 11 when the solid shell box 11 is rotated and adjusted on the top of the rotating shell box 6;

[0067] When the operation is completed, the arm moving motor 401 drives the laser welding arm 10 to reset, the solid shell box 11 will rotate and reset on the top of the rotating shell box 6, and the matching plate 12 will slide and reset in the rectangular groove 406. When the solid shell box 11 is reset, the matching plate 12 moves to its original position and forms a complete slide plate with the inclined groove plate 13, which is convenient for the next slide 9 to move into the solid shell box 11, and plays the role of receiving the movement of the slide 9.
