Description

Technical Field

[0001] The invention belongs to the technical field of auto parts welding, in particular to an auto parts welding 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, have greatly improved production efficiency and product quality, promoting the development of the automobile manufacturing industry.

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

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

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: an automobile parts welding processing machine described in the present invention comprises a base plate, a vertical plate is symmetrically fixedly installed on the top of the base plate, a moving part assembly is arranged between the two vertical plates, the moving part assembly comprises a slide, the slide is used to place the automobile shell, the moving part assembly is used to drive the automobile shell to move through the slide, a rotating shell box is fixedly installed at the top middle position of the base plate, the top of the rotating shell box is rotatably connected to the solid shell box, a solid shell assembly is arranged inside the solid shell box, the solid shell assembly is used to fix the automobile shell, torque boxes are symmetrically fixedly installed on both sides of the rotating shell box, laser welding arms are arranged inside the two torque boxes, two laser welding arms are symmetrically arranged on both sides of the rotating shell box and the solid shell box, a rotating shell assembly is arranged inside the rotating shell box, the rotating shell assembly comprises an indexing wheel, and the rotating shell assembly is used to drive the automobile shell to index through the indexing wheel;

[0007] By placing the car shell into the slide, the moving part assembly 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 assembly 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 assembly in the rotating shell box drives the car shell in the solid shell box to rotate and adjust through the indexing wheel, and cooperates with the laser welding arm to perform welding processing on the car shell, thereby solving the problem in the existing technology that the car shell is relatively wide and 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 assembly 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. When the rotating shell assembly cooperates with the laser welding arm to finish the welding operation on the car shell, the rotating shell assembly is reset, the solid shell assembly releases the car shell in the solid shell box, and the moving part assembly drives the car shell to move out of the solid shell box. At this point, the welding operation on the car shell is completed.

[0008] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion. When the car body is moved into the fixed shell box, the moving motor stops working and the slide moves from the moving rod one to the moving rod two. Then the solid shell component fixes the car body in the slide from both sides of the slide. Then the rotating shell component cooperates with the laser welding arm to weld the car body. The moving motor drives the slide through the moving rod one to drive the car body out of the solid shell box, thereby moving the car body. By extending the length of the moving rod one and adding the number of slides, an assembly line processing can be formed, which can greatly improve production efficiency in the manufacturing process.

[0009] Preferably, the bottom of the slide is rotatably connected to a plurality of wheels, and the plurality of wheels are slidably connected to the top of the guide groove plate. 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. Notches are provided at the bottoms of the pads on both sides. 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 in the slide. The car shell is placed in this way, which greatly ensures the stability of the car shell when it moves, and prevents the car shell from slipping, colliding, etc. when it moves. When the slide moves, the wheels at the bottom of the slide roll and slide on the guide groove plate, and the setting of the wheels is to facilitate the movement of the slide.

[0010] Preferably, the coupling assembly includes a notch shaft and a convex shaft, one end of the notch shaft is fixedly connected to one end of the moving rod one, one end of the convex shaft is fixedly connected to one end of the moving rod two, the outer wall of the other end of the convex shaft is slidably connected to the inner wall of the other end of the notch shaft, the inner wall of the notch shaft is symmetrically fixed with multiple positioning shafts, the outer walls of the multiple positioning shafts are slidably connected with a card shaft, and a return spring is provided between one end of the multiple card shafts and the inner wall of the notch shaft, and the multiple return springs are respectively placed on the outside of the multiple positioning shafts, and the convex shaft The inner wall of the car body is symmetrically provided with multiple circular openings, and the multiple clamping shafts can respectively engage with the inner walls of the multiple circular openings. When the slide drives the car body to pass through the joint assembly into the solid shell box, the solid shell assembly in the solid shell box fixes the car body, and then the two laser welding arms weld the car body in the slide. When it is necessary to rotate and adjust the distance between the car body 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 body 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 moving rod 2. 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 card shaft in the concave end of the concave shaft rod to move. When the card 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 of the positioning shaft under the action of the restoring elastic force of the return 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 movement 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 disconnecting the moving rod one and the moving rod two.

[0011] Preferably, a control button is fixedly installed in the middle position of the inner wall of the solid shell box, and a straight-face groove is opened on the inner wall of the solid shell box. The opening height of the straight-face groove is flush with the inner groove height of the guide groove plate, and multiple wheels can be slidably connected to the inner wall of the straight-face groove. When the slide moves into the solid shell box, the wheels at the bottom of the slide roll in the straight-face groove in the solid shell box. When the slide moves to the designated position, the pad in the slide will squeeze the control button in the solid shell box. When the control button is squeezed, the operation of the moving motor is stopped, and the solid shell assembly and the rotating shell assembly are controlled to operate at the same time, playing a role of positioning control.

[0012] Preferably, the solid shell assembly includes a solid shell arm block, and there are four solid shell arm blocks. The four solid shell arm blocks are symmetrically arranged at the four corners of the solid shell box. The four solid shell arm blocks are all slidably connected to the inner wall of the solid shell box. The inner sides of the bottom ends of the four solid shell arm blocks are fixedly installed with gear rods. The inner wall of the solid shell box is rotatably connected with gears. The teeth on the four gear rods are respectively engaged with the teeth on the two gears in pairs. A connecting rod is fixedly installed between the two gear rods, and two telescopic cylinders are symmetrically fixedly installed on one side of the connecting rod. When the pad contacts the control button, the control button controls the moving motor to stop moving. 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 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 meshing transmission rotation of the gears can drive the other set of solid shell arm blocks to move inward synchronously, and 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 body, the telescopic cylinders are stopped. At this time, the four solid shell arm blocks complete the dead angle retention of the car body, which plays the role of fixing the car body 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 indexing wheel, so that when the laser welding arms adjust their positions, the rotating shell assembly drives the car body to also adjust to cooperate with the position adjustment of the two laser welding arms, thereby playing a role in coordinated adjustment.

[0014] Preferably, the rotating shell assembly also includes an indexing shaft, the indexing wheel is rotatably connected to the inner wall of the rotating shell box, the indexing shaft is fixedly installed on the top of the indexing wheel, the top end of the indexing shaft passes through the inner wall of the rotating shell 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 indexing rod, the teeth on the two indexing rods are engaged with the teeth on the indexing wheel, when the arm moving motor drives the laser welding arm to move through the square block, the square block synchronously drives the indexing rod to move through the L-shaped square rod, and the indexing rod will drive the indexing wheel to rotate when it moves, and when the indexing wheel rotates, it can drive the solid shell box to index on the top of the rotating shell box through the indexing shaft, thereby 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 while synchronously adjusting the position of the car shell.

[0015] Preferably, one side of the two L-shaped moment rods is fixedly installed with a moving plate rod, the inner wall of the bottom plate is symmetrically provided with moment grooves, the inner walls of the two moment grooves are slidably connected with a fitting plate, one side of the two fitting plates is slidably connected to one side of the two guide groove plates, the inner groove height of the two fitting plates is the same as the inner groove height of the two guide groove plates, and one end of the two moving plate rods is fixedly connected to the bottom of the two fitting plates. When the moving arm motor drives the transfer rod to move through the L-shaped moment rod, the L-shaped moment rod drives the fitting plate to slide in the moment groove through the moving plate rod, thereby causing the fitting plate to move out from one end of the guide groove plate, avoiding the setting of the fitting plate affecting the transfer of the solid shell box when the solid shell box is rotated and adjusted on the top of the rotating shell box.

[0016] Preferably, the outer wall of the solid shell box is symmetrically fixed with inclined slot plates, and the two inclined slot plates can respectively fit the inner walls of the two fitting plates, and the two can form a complete slide plate when fitted. When the operation is completed, the arm moving motor drives the laser welding arm to reset, and the solid shell box will rotate and reset on the top of the rotating shell box, and the fitting plates will slide and reset in the rectangular groove. When the solid shell box is reset, the fitting plates move to their original position, forming a complete slide plate with the inclined slot plates, which facilitates the movement of the next slide into the solid shell box and plays the role of taking over the movement of the slide.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The automobile parts welding processing machine described in the present invention drives the laser welding arm to move its position through the arm moving motor via the moment block. When the two laser welding arms move back to adjust their positions, the moment block synchronously drives the indexing rod to move via the L-shaped moment rod. When the indexing rod moves, it drives the indexing wheel to rotate. When the indexing wheel rotates, it can drive the solid shell box to index on the top of the shell rotating box through the indexing shaft, thereby indexing and adjusting the position of the automobile shell in the solid shell box. By moving the position of the laser welding arm, the position of the automobile shell is adjusted, and the two can cooperate in the adjustment operation, thereby achieving the synchronous adjustment of the position of the automobile shell while adjusting the position of the laser welding arm.

[0019] 2. The automobile parts welding processing machine described in the present invention drives the moving rod 1 to rotate through the moving motor.

When the slide moves to one end of the moving rod 1, the moving rod 1 and the moving rod 2 can be connected as a whole through the setting of the joint component. When the moving motor drives the automobile shell into the solid shell box through the moving rod 1, the slide will move from the moving rod 1 to the moving rod 2, playing the role of moving the automobile 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 production efficiency in the manufacturing process.

[0020] When the cam is in the closed position, the cam is released and the cam is released, so that the cam is in the closed position and the cam is released, and the cam is released and the cam is released, so that the cam is released and the cam is released, and the cam is released and the cam is released, so that the cam is released and the cam is released, and the cam is released and the cam is released, so that the cam is released and the cam is released,

[0021] 4. The automobile parts welding processing machine described in the present invention is configured such that when the pad contacts the machine control button, the machine control button controls the two telescopic cylinders to operate. The telescopic cylinder drives two of the gear rods 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 meshing transmission rotation of the gears can drive the other group of solid shell arm blocks to move inward synchronously. The two groups of solid shell arm blocks will move inward at the same time. When the four solid shell arm blocks contact the car body, the telescopic cylinder is stopped. At this time, the four solid shell arm blocks complete the dead angle retention of the car body, thereby 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 easier to understand, the present invention is further described 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 includes a base plate 1, a vertical plate 3 is symmetrically fixedly installed on the top of the base plate 1, a moving part assembly is arranged between the two vertical plates 3, the moving part assembly includes a slide 9, the slide 9 is used to place the automobile shell, and the moving part assembly is used to drive the automobile shell to move through the slide 9, a rotating shell box 6 is fixedly installed at the top middle position of the base plate 1, the top of the rotating shell box 6 is rotatably connected to the solid shell box 11, a solid shell assembly is arranged inside the solid shell box 11, and the solid shell assembly is used to fix the automobile shell, torque boxes 4 are symmetrically fixedly installed on both sides of the rotating shell box 6, laser welding arms 10 are arranged inside the two torque boxes 4, two laser welding arms 10 are symmetrically arranged on both sides of the rotating shell box 6 and the solid shell box 11, a rotating shell assembly is arranged inside the rotating shell box 6, the rotating shell assembly includes an indexing wheel 404, and the rotating shell assembly is used to drive the automobile shell to index through the indexing 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 using the laser welding arm 10 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 too large. 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 blind 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, 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 connected with the two guide rails 3 and the two guide rails 3 are connected to each other by the spring 7 and the spring 7 is connected to the two guide rails 3.

[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 inside the slide 9 from both sides of the slide 9, and then the rotating shell component will cooperate with the laser welding arm 10 to weld the car body, and the moving motor 2 will drive the slide 9 through the moving rod 1 7 to drive the car body out of the solid shell box 11, thereby moving 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 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 running wheels 902, and the plurality of running 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 the car shell is placed 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 inside 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 wheel 902 at the bottom of the slide 9 rolls and slides on the guide groove plate 5. The setting of the wheel 902 is to facilitate the movement of the slide 9.

[0044] like Figures 10 to 12 As shown, the coupling assembly 8 includes a recessed shaft rod 801 and a convex shaft rod 802, one end of the recessed shaft rod 801 is fixedly connected to one end of the moving rod 7, one end of the convex shaft rod 802 is fixedly connected to one end of the moving 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 recessed shaft rod 801, and the inner wall of the recessed shaft rod 801 is symmetrically fixed with multiple positioning shafts 803, and the outer walls of the multiple positioning shafts 803 are slidably connected with a clamping shaft 804, and return springs 805 are provided between one end of the multiple clamping shafts 804 and the inner wall of the recessed shaft rod 801, and the multiple return springs 805 are respectively placed on the outside of the multiple positioning shafts 803, and the inner wall of the convex shaft rod 802 is symmetrically opened with multiple circular openings 806, and the multiple clamping shafts 804 can be respectively engaged with the inner walls of the multiple circular openings 806;

[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 place by the solid shell assembly in the solid shell box 11 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 moving rod 2 71. 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 802 will thereby 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 When the convex shaft 802 is reset, the card shaft 804 loses the squeezing thrust of the convex shaft 802, and the card shaft 804 slides out from the positioning shaft 803 under the action of the reset elastic force of the reset spring 805, and one end of the card shaft 804 is stuck in the circular opening 806, thereby connecting the concave shaft 801 and the convex shaft 802, so that the moving rod is When the housing 11 is rotated, the two moving rods 701 can be driven to rotate together, thereby moving the slide 9 out of the solid shell 11. At the same time, the setting of the joint assembly 8 can make the housing assembly rotate without interfering with the rotation of the moving rod 1 7 and the moving rod 2 71, thereby disconnecting the moving rod 1 7 and the moving rod 2 71. It should be noted that the length between the notched shaft 801 and the convex shaft 802 is less than the distance between the three sets of threaded openings opened in the slide 9.

[0046] like Figures 1 to 5 As shown, a control button 14 is fixedly installed in the middle position of the inner wall of the solid shell box 11, and a straight groove 15 is opened on the inner wall of the solid shell box 11. The opening height of the straight groove 15 is flush with the inner groove height of the guide groove plate 5, and the multiple wheels 902 can be slidably connected to the inner wall of the straight 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 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 assembly and the rotating shell assembly 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. 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. The inner wall of the solid shell box 11 is rotatably connected to a gear 1103. The teeth on the four gear rods 1102 are respectively engaged with the teeth on the two gears 1103. 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 cylinder 1105 is operating, it drives two of the gear rods 1102 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, it rotates through the meshing transmission of the gear 1103, which can drive the other group of solid shell arm blocks 1101 to move inward synchronously. 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 cylinder 1105 is stopped. At this time, the four solid shell arm blocks 1101 complete the dead angle retention of the car shell, which plays the role of fixing the car shell during welding.

[0050] like Figures 8 and 9 As shown, the inner walls of the two torque boxes 4 are fixedly mounted with arm moving motors 401, and the output ends of the two arm moving motors 401 are mounted 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 mounted 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 body to adjust as well, thereby coordinating the position adjustment of the two laser welding arms 10, 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 moment 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 engaged 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 index on the top of the rotating shell box 6 through the indexing shaft 16, thereby adjusting 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 to adjust the operation, thereby adjusting the position of the laser welding arm 10 while synchronously adjusting the position of the car shell.

[0054] like Figures 7 to 9 As shown, a plate shifting rod 405 is fixedly installed on one side of the two L-shaped moment rods 403, and a moment groove 406 is symmetrically opened on the inner wall of the bottom plate 1. The inner walls of the two moment 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. 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 indexing 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 moving rod 405, so that the engaging plate 12 moves out from one end of the guide groove plate 5, preventing the setting of the engaging 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.

[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 the inner walls of the two fitting plates 12, and the two can form a complete slide when fitted together;

[0057] When the operation is completed, the arm 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 facilitates the movement of the next slide 9 into the solid shell box 11 and plays the role of taking over 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 weld 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 weld the car shell, thereby solving the existing technology In the embodiment, the car body is relatively wide, and the extension distance of the laser welding arm 10 is within 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 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 to move out of the solid shell box 11. At this point, the welding operation of the car body 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 will cooperate with the laser welding arm 10 to weld the car body, and the moving motor 2 will drive the slide 9 through the moving rod 1 7 to drive the car body out of the solid shell box 11, thereby moving the car body. By extending the length of the moving rod 1 7 and increasing the number of slides 9, an assembly line process can be formed, which can greatly improve production efficiency in the manufacturing process.

[0060] When the car shell is placed 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 in 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 runner 902 at the bottom of the slide 9 rolls and slides on the guide groove plate 5. The setting of the runner 902 is to facilitate the movement of the slide 9;

[0061] 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, since the car body is fixed in the solid shell box 11 by the solid shell assembly, 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 body to rotate and the welding operation is completed, the rotating shell assembly drives the car body to reset, and the convex shaft rod 802 will thereby move back into the concave shaft rod 801. When the convex shaft 802 is in the concave shaft rod 80 When the cam 802 is in the state of being reset, the cam 804 loses the squeezing force of the cam 802 and the cam 804 slides out of the positioning shaft 803 under the action of the restoring elastic force of the restoring spring 805. One end of the cam 804 is locked in the circular opening 806, thereby connecting the recessed shaft 801 and the cam 802. When the moving rod 1 is rotated, the moving rod 1 7 can drive the moving rod 2 71 to rotate together, 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 engaging assembly 8 can make it possible for the moving rod 1 7 and the moving rod 2 71 to not interfere with its rotation when the rotating shell assembly rotates, thereby playing the role of disconnecting the moving rod 1 7 and the moving rod 2 71.

[0062] When the slide 9 moves into the solid shell 11, the rotating wheel 902 at the bottom of the slide 9 rolls in the straight groove 15 in the solid shell 11. When the slide 9 moves to the designated position, the pad 901 in the slide 9 presses the control button 14 in the solid shell 11. When the control button 14 is pressed, the operation of the moving motor 2 is stopped, and the solid shell assembly and the rotating shell assembly are controlled to operate, thereby playing 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 cylinder 1105 is operating, it drives two of the gear rods 1102 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, it rotates through the meshing transmission of the gear 1103, which can drive the other group of solid shell arm blocks 1101 to move inward synchronously. 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 cylinder 1105 is stopped. At this time, the four solid shell arm blocks 1101 complete the dead angle retention of the car shell, which plays the role of 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 is also 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. When the laser welding arm 10 adjusts its position, the rotating shell assembly drives the car body to adjust as well, thereby coordinating the position adjustment of the two laser welding arms 10, playing a role in 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. When the indexing rod 407 moves, it drives the indexing wheel 404 to rotate. When the indexing wheel 404 rotates, it can drive the solid shell box 11 to index on the top of the shell rotating box 6 through the indexing shaft 16, thereby adjusting the position of the car shell in the solid shell box 11. By adjusting the position of the laser welding arm 10, the position of the car shell can be adjusted. The two can cooperate with each other to adjust the operation, thereby adjusting the position of the laser welding arm 10 and synchronously adjusting the position of the car shell;

[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 engaging plate 12 to slide in the moment groove 406 through the plate moving rod 405, so that the engaging plate 12 moves out from one end of the guide groove plate 5, thereby preventing the setting of the engaging 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 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 facilitates the movement of the next slide 9 into the solid shell box 11 and plays the role of taking over the movement of the slide 9.
