[0002] The volute and the turbine housing of a turbocharger, also known as the volute of the turbocharger, are important components of the turbocharger and are mainly used to drive the turbine of the turbocharger to rotate. The design and material selection of the turbine housing have an important impact on the performance and reliability of the turbocharger.

[0003] The intermediate piece in the middle of the turbine housing is generally welded to the turbine housing by laser welding technology. However, there are still some defects in the existing laser welding tooling during the laser welding process:

[0004] 1. Most of the existing laser welding tooling can only fix the turbine housing to enable the laser welding machine to stably complete the laser welding operation. After the turbine housing is fixed by the tooling, the operator still needs to manually rotate the laser welding tooling to make the turbine housing rotate to complete the laser welding process, resulting in inconvenient laser welding of the turbine housing.

[0005] 2. At the same time, since the laser welding tooling can only fix the turbine housing, after the laser welding process of the turbine housing is completed, the operator needs to manually complete the blanking of the turbine housing, resulting in low welding processing efficiency of the turbine housing, and high operation intensity and high operation cost during the laser welding process of the turbine housing.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment: As Figures 1-9As shown in the figure, the present invention provides a volute laser welding tooling device, which includes a device ring 1. A U-shaped fixing frame 11 is fixedly installed on the upper end surface of the device ring 1. One end of the U-shaped fixing frame 11 is fixedly installed with a device seat 12. The device seat 12 is coaxial with the device ring 1. Two fixing rings 13 are arranged inside the device ring 1. Placing disks 14 are rotatably installed on the inner walls of the two fixing rings 13. An installation groove 15 is formed on the upper end surface of the device ring 1. A limiting mechanism 2 is arranged on the two placing disks 14. A switching mechanism 3 is arranged between the device ring 1 and the two fixing rings 13. A rotating mechanism 5 is arranged on the lower end surface of the device ring 1. A blanking mechanism 6 is arranged between the two placing disks 14 and the device seat 12. By providing the installation groove 15, it is convenient to assemble the welding torch of the laser welder above the device ring 1 through the installation groove 15. By providing two placing disks 14, it is convenient for loading and unloading of two volutes to be welded. By providing the limiting mechanism 2, the limiting mechanism 2 can limit the volute on the placing disk 14, thereby avoiding the situation of deviation of the volute and the intermediate piece during laser welding. By providing the switching mechanism 3, the switching mechanism 3 can make the two placing disks 14 rotate circumferentially inside the device ring 1, so that one placing disk 14 is located below the welding torch of the laser welder and the other placing disk 14 is separated from the welding torch. By providing the rotating mechanism 5, the rotating mechanism 5 can make the placing disk 14 rotate self, so that the volute and the intermediate piece rotate self during welding, so as to automatically complete laser welding processing. By providing the blanking mechanism 6, the blanking mechanism 6 can make the placing disk 14 flip downward, and make the limiting mechanism 2 release the limit on the volute and the intermediate piece, and then make the placing disk 14 flip back to the reset state, automatically realizing the separation of the volute after laser welding from the placing disk 14, thereby improving the welding efficiency of the volute.

[0034] The limiting mechanism 2 includes four arc-shaped limiting plates 21. Guide grooves 22 are formed on both of the two placing disks 14. Two guide blocks 23 are slidably installed on the inner walls of the two guide grooves 22. The upper surface of one of the guide blocks 23 is fixedly connected to the lower end surface of one of the arc-shaped limiting plates 21. A bidirectional lead screw 24 is rotatably installed inside both of the two placing disks 14. One of the bidirectional lead screws 24 penetrates through one of the guide grooves 22 and is in threaded rotation connection with the two adjacent guide blocks 23. By providing two arc-shaped limiting plates 21 on both of the two placing disks 14, after the volute and the intermediate piece are placed on the placing disk 14 (the intermediate piece is located at the axis position of the volute), by driving the two arc-shaped limiting plates 21 to approach each other, the volute can be limited and fixed on the upper surface of the placing disk 14. By rotating the bidirectional lead screw 24, the bidirectional lead screw 24 can drive the two guide blocks 23 to slide towards each other or away from each other in the guide groove 22, and the guide blocks 23 can make the arc-shaped limiting plates 21 move synchronously.

[0035] Fixed plates 25 are fixedly installed on both of the two placing trays 14. Rotating shafts 26 are rotatably installed on both of the two fixed plates 25. One ends of the two rotating shafts 26 are fixedly installed with first gears 27. One ends of the two bidirectional lead screws 24 are fixedly installed with second gears 28. One of the first gears 27 and one of the second gears 28 are meshed and connected. The other ends of the two rotating shafts 26 are fixedly installed with transmission gears 29. By driving the first gear 27 or the transmission gear 29 to rotate, the first gear 27 can make the bidirectional lead screw 24 rotate through the second gear 28, and the transmission gear 29 can make the first gear 27 rotate through the rotating shaft 26, and can also drive the bidirectional lead screw 24 to rotate.

[0036] The switching mechanism 3 includes a circular guide rail 31. The circular guide rail 31 is fixedly installed on the inner wall of the equipment ring 1. Two arc-shaped sliders 32 are slidably installed on the circular guide rail 31. Connecting shafts 33 are rotatably installed on the opposite sides of the two arc-shaped sliders 32. One end of one of the connecting shafts 33 is fixedly connected to the outer wall of a fixed ring 13. Driving rods 34 are fixedly installed on the outer walls of the two fixed rings 13. Connecting rods 35 are fixedly installed at one ends of the two driving rods 34. Guide rollers 36 are rotatably installed at one ends of the two connecting rods 35. A circular groove 37 is formed in the outer wall of the equipment seat 12. The outer walls of the two guide rollers 36 are in movable contact with the inner wall of the circular groove 37. By driving the arc-shaped sliders 32 to slide circumferentially on the circular guide rail 31, the arc-shaped sliders 32 can make the fixed ring 13 and the placing tray 14 revolve around the inner circumference of the equipment ring 1 through the connecting shafts 33, so as to realize the switching of the two placing trays 14, and transfer the volute and the intermediate piece after laser welding processing to the outside of the processing range. By providing the driving rods 34, the connecting rods 35, the guide rollers 36 and the circular groove 37, when the fixed ring 13 and the placing tray 14 revolve around the circle, the fixed ring 13 and the placing tray 14 make the guide rollers 36 rotate circumferentially in the circular groove 37 through the driving rods 34 and the connecting rods 35, and the guide rollers 36 support the fixed ring 13 and the placing tray 14 through the connecting rods 35 and the driving rods 34, thereby improving the stability of the fixed ring 13 and the placing tray 14.

[0037] The switching mechanism 3 further includes a motor 38. A first rotating rod 39 is fixedly installed at the driving output end of the motor 38. One end of the first rotating rod 39 is fixedly installed with a U-shaped connecting frame 4. One end of the U-shaped connecting frame 4 is fixedly installed with a rotating ring 41. The rotating ring 41 is coaxial with the circular guide rail 31. A plurality of first teeth 42 distributed in a circular array are fixedly installed on the upper surface of the rotating ring 41. The switching mechanism 3 further includes an L-shaped fixing frame 43. A second rotating rod 44 is rotatably installed at one end of the L-shaped fixing frame 43. One end of the second rotating rod 44 is fixedly installed with a third gear 45. The third gear 45 is located above the first teeth 42. The other end of the second rotating rod 44 is fixedly installed with a fourth gear 46. Tooth discs 47 are fixedly installed on the lower surfaces of the two arc-shaped sliders 32. The fourth gear 46 is meshed with the tooth discs 47. By turning on the motor 38, the driving shaft of the motor 38 can make the first rotating rod 39 rotate. The first rotating rod 39 can make the rotating ring 41 and the first teeth 42 rotate circumferentially through the U-shaped connecting frame 4. When the first teeth 42 are meshed with the third gear 45, the first teeth 42 can drive the third gear 45 to rotate. The third gear 45 can make the fourth gear 46 rotate through the second rotating rod 44. The fourth gear 46 can drive the tooth discs 47 to rotate. The tooth discs 47 can make the arc-shaped sliders 32 slide circumferentially on the circular guide rail 31. When the first teeth 42 are meshed with the third gear 45 once, the arc-shaped sliders 32 slide circumferentially for half a turn, so that one placement tray 14 enters the laser welding processing area and the other placement tray 14 exits the laser welding processing area.

[0038] The rotating mechanism 5 includes a third rotating rod 51. An arc-shaped block 52 is fixedly installed at one end of the third rotating rod 51. Arc-shaped grooves 53 are formed on one side of each of the two placement trays 14. The arc-shaped block 52 is in movable contact with the middle of one of the arc-shaped grooves 53. By providing the arc-shaped block 52 and the arc-shaped grooves 53, when either of the two placement trays 14 rotates to the laser welding processing area, the arc-shaped block 52 is located in the middle of the arc-shaped groove 53. By driving the third rotating rod 51 to rotate, the third rotating rod 51 can make the placement tray 14 rotate through the arc-shaped block 52 and the arc-shaped groove 53, and the volute and the intermediate piece on the placement tray 14 rotate synchronously.

[0039] A transmission rod 54 is rotatably installed at one end of the L-shaped fixing frame 43. Bevel gears 55 are fixedly installed at one end of the transmission rod 54 and the middle of the third rotating rod 51 respectively. The two bevel gears 55 are meshed with each other. By driving the transmission rod 54 to rotate, the transmission rod 54 can make the third rotating rod 51 rotate through the two bevel gears 55.

[0040] At the other end of the transmission rod 54, a fifth gear 56 is fixedly installed. On the lower surface of the rotating ring 41, a number of second teeth 57 are fixedly installed in a circular array. The second teeth 57 are meshed with the fifth gear 56. When the rotating ring 41 rotates, the rotating ring 41 causes the second teeth 57 to rotate circumferentially. When the second teeth 57 are meshed with the fifth gear 56 and drive the fifth gear 56 to rotate one full circle, the fifth gear 56 causes the transmission rod 54 to rotate, thereby enabling the placement disk 14 to rotate one full circle.

[0041] The blanking mechanism 6 includes two drive gears 61. One side of one of the drive gears 61 is fixedly connected to one end of a drive rod 34. A circular ring 62 is fixedly installed on the outer wall of the equipment base 12. On the upper end surface of the circular ring 62, a number of third teeth 63 are fixedly installed in a circular array. On the upper end surface of the circular ring 62, a number of fourth teeth 64 are also fixedly installed in a circular array. The number of third teeth 63 and the number of fourth teeth 64 are located below the drive gear 61. By providing the drive gear 61, the third teeth 63, and the fourth teeth 64, when the placement disk 14 revolves around the circumference, the drive gear 61 revolves synchronously. When the drive gear 61 is meshed with the third teeth 63, the third teeth 63 cause the drive gear 61 to rotate half a circle. The drive gear 61 can cause the fixed ring 13 and the placement disk 14 to flip 180 degrees through the drive rod 34. The volute and the intermediate member facing vertically upward are flipped downward. When the drive gear 61 revolves around the circumference to the position of the fourth teeth 64, the fourth teeth 64 cause the drive gear 61 to rotate 180 degrees again, thereby flipping the placement disk 14 back to its original position for the operator to place the volute and the intermediate member to be laser welded on the placement disk 14.

[0042] A first fixing rod 65 is fixedly installed on the upper end surface of the equipment base 12, and a first arc-shaped toothed plate 66 is fixedly installed on one end of the first fixing rod 65. The first arc-shaped toothed plate 66 is located above the first gear 27. Two second fixing rods 67 are fixedly installed on the inner wall of the equipment ring 1, and a second arc-shaped toothed plate 68 is fixedly installed on one end of the two second fixing rods 67. The second arc-shaped toothed plate 68 is located below the transmission gear 29. By arranging the first arc-shaped toothed plate 66 and the second arc-shaped toothed plate 68, when the first gear 27 follows the placement disk 14 to rotate around the circumference to the position of the first arc-shaped toothed plate 66, the first arc-shaped toothed plate 66 causes the first gear 27 to rotate, and when the transmission gear 29 follows the placement disk 14 to rotate around the circumference to the position of the second arc-shaped toothed plate 68, the second arc-shaped toothed plate 68 causes the first gear 27 to rotate. The tooth plate 68 drives the transmission gear 29 to rotate. Due to the staggered setting of the first arc-shaped tooth plate 66 and the second arc-shaped tooth plate 68, the rotation direction of the transmission gear 29 is opposite to that of the first gear 27, so that the bidirectional screw 24 rotates in positive and negative directions, and the two arc-shaped limit plates 21 move away from and approach each other. That is, after the placement plate 14 is flipped for the first time, the volute is flipped downward, the two arc-shaped limit plates 21 move away from each other, and the volute falls downward and separates from the placement plate 14. After the placement plate 14 is flipped and reset for the second time, the operator places the volute and intermediate parts to be laser welded on the placement plate 14, and the two arc-shaped limit plates 21 approach each other to limit and fix the volute and the intermediate parts, thereby realizing automatic unloading of the volute after laser welding.

[0043] Working principle: Before using the tool, first install the laser welder at the position of the installation groove 15, and the welding gun of the laser welder is vertically corresponding to one of the placement plates 14;

[0044] When the intermediate piece needs to be welded at the center of the volute, during the first operation, the operator manually turns a corresponding second gear 28 to rotate, and the second gear 28 rotates a bidirectional lead screw 24, and the bidirectional lead screw 24 drives the corresponding two guide blocks 23 to slide back to back, and the two guide blocks 23 move the two arc-surface limit plates 21 away from each other, so that the two arc-surface limit plates 21 are in an open state;

[0045] Subsequently, the operator places the volute at the center position of a placing disk 14, and places the intermediate piece at the center position of the volute. Then, the operator reversely turns the second gear 28 to rotate, so that the corresponding two arc-shaped limiting plates 21 approach each other to limit and fix the volute. At this time, the operator turns on the motor 38 and makes the laser welder work synchronously. The driving shaft of the motor 38 makes the first rotating rod 39 rotate. The first rotating rod 39 can make the rotating ring 41, a plurality of first teeth 42 and a plurality of second teeth 57 rotate circumferentially through the U-shaped connecting frame 4. The plurality of second teeth 57 drive the fifth gear 56 to rotate one circle. The fifth gear 56 makes the transmission rod 54 rotate. The transmission rod 54 makes the third rotating rod 51 rotate through two bevel gears 55. The third rotating rod 51 makes a placing disk 14 rotate one circle through the arc-shaped block 52 and a corresponding arc-shaped groove 53. The volute and the intermediate piece on a placing disk 14 rotate synchronously to cooperate with the welding operation. The welder performs laser welding on the joint between the intermediate piece and the volute, thus conveniently realizing the automatic welding of the volute and the intermediate piece, and effectively improving the convenience of the volute welding process;

[0046] Meanwhile, as a placing disk 14 rotates one circle and the welding of the volute and the intermediate piece is completed, the welding torch of the laser welder rises and resets to the initial height. The plurality of second teeth 57 disengage from the fifth gear 56. At this time, the plurality of first teeth 42 engage with the third gear 45. The plurality of first teeth 42 drive the third gear 45 to rotate. The third gear 45 makes the fourth gear 46 rotate through the second rotating rod 44. The fourth gear 46 drives the toothed disk 47 to rotate. The toothed disk 47 makes two arc-shaped sliders 32 slide circumferentially on the circular guide rail 31 for half a circle. The two arc-shaped sliders 32 make two fixing rings 13 and two placing disks 14 revolve half a circle on the inner circumference of the equipment ring 1. At this time, the volute and the intermediate piece after laser welding are transferred outside the processing range, and another placing disk 14 enters the laser welding processing area;

[0047] During the process of the two placement disks 14 revolving around the circle by half a turn, the two driving gears 61 revolve synchronously. When one driving gear 61 on the placement disk 14 with the volute and the intermediate piece placed thereon meshes with a plurality of third teeth 63, the plurality of third teeth 63 cause the driving gear 61 to rotate by half a turn. One driving gear 61 causes a fixed ring 13 and a placement disk 14 to flip by 180 degrees through the corresponding driving rod 34. At this time, the volute and the intermediate piece that are vertically upward are flipped downward. Then, the first gear 27 on one placement disk 14 meshes with the first arc-shaped tooth plate 66, and the first arc-shaped tooth plate 66 causes the first gear 27 to rotate. At this time, the corresponding two arc-shaped limiting plates 21 move away from each other, and the volute and the intermediate piece below one placement disk 14 fall downward and are separated from the placement disk 14. Then, one driving gear 61 meshes with a plurality of fourth teeth 64, and the fourth teeth 64 cause the driving gear 61 to rotate by 180 degrees again. At this time, one placement disk 14 flips back to its original position. At this time, the operator places the volute and the intermediate piece to be laser welded on one placement disk 14. Then, one transmission gear 29 meshes with the second arc-shaped tooth plate 68, and the second arc-shaped tooth plate 68 drives one transmission gear 29 to rotate, and the rotation direction of the transmission gear 29 is opposite to the rotation direction of the first gear 27, so as to reverse the rotation of the bidirectional lead screw 24, and the two arc-shaped limiting plates 21 move closer to each other to limit and fix the volute and the intermediate piece, so as to facilitate the next laser welding operation. Thus, the automatic blanking of the volute after laser welding processing is conveniently realized, and the automatic limiting and fixing of the volute after the feeding operation are completed. Furthermore, the efficiency of the laser welding processing of the volute is effectively improved, and the labor intensity and operation cost of manual operation are reduced. At the same time, the functionality of the laser welding tooling for the volute is improved.
