Description

Technical Field

[0001] The present invention relates to the technical field of turbocharger processing, in particular to a welding tool for an automobile turbocharger housing. Background Art

[0002] The turbocharger increases the engine's intake volume by compressing air, thereby improving combustion efficiency and power output. The turbocharger consists of a turbine housing, an intermediate housing, and a turbine shaft. The intermediate housing is mainly used to support the turbine shaft's high-speed rotation through precision bearings. A Z-shaped shaft runs through the side of the intermediate housing. One end of the Z-shaped shaft that passes through the intermediate housing is connected to an 8-shaped stopper (such as Figure 10 shown).

[0003] The existing tooling used to secure the intermediate housing and retaining plate during the turbocharger housing welding process typically involves manually placing the intermediate housing on a workbench, quickly securing it with a pneumatic clamp, then installing the Z-axis onto the intermediate housing, and then installing the retaining plate onto the Z-axis. A gasket is also placed beneath the retaining plate to ensure its horizontality, and finally, the retaining plate is secured by pressing down with a pressure piece. However, this method is cumbersome and overly reliant on manual operation, resulting in low processing efficiency. Furthermore, manual operation makes it difficult to ensure the consistency of subsequent welding quality. The existing tooling simply secures the intermediate housing and retaining plate with pneumatic clamps and pressure pieces, lacking precise positioning and limiting mechanisms. This makes it difficult to ensure the relative positional accuracy of the intermediate housing, Z-axis, and retaining plate, resulting in unstable welding quality and, in turn, affecting the overall performance and service life of the turbocharger.

[0034] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will结合附图对本发明的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本发明。但是本发明能够以很多不同于在此描述的其它方式来实施,本领域技术人员可以在不违背本发明内涵的情况下做类似改进,因此本发明不受下面公开的具体实施例的限制。

[0035] As Figure 1 、 Figure 2 And<000,0091>shown, an automobile turbocharger housing welding tooling includes an equipment rack 10; a bottom plate 11 is fixedly installed on the equipment rack 10, and a fixing mechanism 3 for positioning and fixing the middle housing and a conveying mechanism 2 for removing the welded middle housing for blanking are arranged on the bottom plate 11

[0036] As Figure 2 、 Figure 3 And Figure 5As shown, the conveying mechanism 2 includes a support plate 20, and two front-to-back symmetrical support plates 20 are fixedly installed on the upper end of the base plate 11. A roller 21 is installed between the two support plates 20 to rotate evenly from left to right, and the rollers 21 are connected by a pulley mechanism.

[0037] like Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the fixing mechanism 3 includes a No. 1 cylinder 30, and the No. 1 cylinder 30 is fixedly installed at the lower end of the base plate 11. After the telescopic section of the No. 1 cylinder 30 slides through the base plate 11, it is fixedly installed with a fixing plate 31 located below the roller shaft 21. The upper end of the fixing plate 31 is fixedly installed with two left-right symmetrical support plates 32 located between the corresponding two roller shafts 21 through a support.

[0038] like Figure 2 and Figure 6 As shown, the support plate 32 is provided with a positioning portion 34 for aligning the intermediate shell, and the bottom plate 11 is provided with a fixing portion 35 for fixing the intermediate shell and a limiting portion 33 for limiting and fixing the Z-axis 101 and the stopper 102.

[0039] During specific work, the intermediate shell is placed at the corresponding position of the roller shaft 21 by manual or robotic arms, and then the Z-shaped shaft 101 and the stop plate 102 are installed on the intermediate shell by manual or robotic arms. Then the No. 1 cylinder 30 pushes the fixed plate 31 to move upward, and the fixed plate 31 pushes the intermediate shell to move upward through the support plate 32, so that the intermediate shell is higher than the roller shaft 21. Then, the intermediate shell is straightened and fixed by the positioning part 34 and the fixing part 35, and then the limiting part 33 straightens and fixes the Z-shaped shaft 101 and the stop plate 102, and then the stop plate 102 is welded to the Z-shaped shaft 101 by an external welding mechanism.

[0040] After welding is completed, the limiting part 33 releases the fixation of the Z-axis 101 and the stop plate 102, and then the positioning part 34 and the fixing part 35 release the fixation of the intermediate shell. Then the No. 1 cylinder 30 pulls the fixing plate 31 downward, and the fixing plate 31 drives the support plate 32 to move downward, and the intermediate shell moves downward synchronously with the support plate 32 until the intermediate shell contacts the roller shaft 21. Then the fixing plate 31 continues to move downward so that the positioning part 34 is lower than the upper surface of the roller shaft 21. Then the external motor drives one of the roller shafts 21 to rotate, and the remaining roller shafts 21 rotate synchronously through the pulley mechanism. The rotation of the roller shaft 21 drives the welded intermediate shell to move to the right for subsequent processing, and then the intermediate shell to be processed is placed again for welding.

[0041] like Figure 2 、 Figure 3 、 Figure 7 and Figure 8As shown, the fixed part 35 includes a No. 2 cylinder 350, and the upper end of the base plate 11 is fixedly installed with the No. 2 cylinder 350 located between the two support plates 20. The telescopic section of the No. 2 cylinder 350 slides through the rear support plate 20 and is fixedly installed with a push plate 351. The rear end of the push plate 351 is fixedly installed with a vertical plate 352, and the front end of the vertical plate 352 is fixedly installed with a connecting plate 353. Two left-right symmetrical rectangular plates 354 are installed on the connecting plate 353 for sliding left and right. The connecting plate 353 is provided with an extrusion part 7 that contacts with the intermediate shell and is used to drive the rectangular plate 354 to extrude the intermediate shell. The rectangular plate 354 is provided with a clamping part 8 for squeezing the intermediate shell and tightly fitting it to the support plate 32.

[0042] like Figure 7 and Figure 8 As shown, the extrusion member 7 includes a drive plate 70, and the drive plate 70 is provided on the rear side of the connecting plate 353. Two left-right symmetrical sliding rods 71 ​​are fixedly installed at the front end of the drive plate 70. After the front end of the sliding rod 71 slides through the connecting plate 353, a supporting plate 72 that contacts the intermediate shell is fixedly installed thereon. A No. 1 tension spring 73 corresponding to the sliding rod 71 and sleeved on the sliding rod 71 is fixedly installed between the drive plate 70 and the connecting plate 353. A connecting rod 74 is hinged between the drive plate 70 and the rectangular plate 354.

[0043] During operation, the No. 1 cylinder 30 pushes the supporting plate 32 upward through the fixing plate 31, and the supporting plate 32 first contacts the bottom of the intermediate shell through the positioning portion 34, and pushes the intermediate shell to move upward and away from the roller shaft 21 through the positioning portion 34, and under the gravity of the intermediate shell, it will also drive the positioning portion 34 to conflict with the outer ring wall of the intermediate shell, but at this time the positioning portion 34 cannot push the intermediate shell to be completely straightened, and then the No. 2 cylinder 350 pulls the vertical plate 352 forward through the push plate 351, and the vertical plate 352 drives the connecting plate 353 to move forward, and the connecting plate 353 drives the supporting plate 7 2 conflicts with the middle shell, and the support plate 72 cannot move further at this time. Then, as the connecting plate 353 continues to move, the tension spring 73 No. 1 is stretched to continue to move toward the middle shell, and the movement of the connecting plate 353 drives the two rectangular plates 354 to approach each other through the connecting rod 74, and the rectangular plates 354 squeeze and fix the middle shell. In the process of the rectangular plates 354 approaching the middle shell, the pressing member 8 will also squeeze the middle shell downward. The middle shell squeezed downward will be in close contact with the supporting plate 32, and at the same time, the positioning portion 34 will further move the middle shell to be straightened and limited.

[0044] The No. 2 cylinder 350 drives the connecting plate 353 away from the middle shell through the push plate 351 and the vertical plate 352. The connecting plate 353 first drives the rectangular plate 354 away from the middle shell through the connecting rod 74 to release the fixation of the middle shell. Then the connecting plate 353 drives the rectangular plate 354 and the abutment plate 72 to move backward away from the middle shell to avoid interfering with the middle shell moving to the right to unload.

[0045] As Figure 2 , Figure 5 and Figure 6 shown, the positioning part 34 includes a chute. Two symmetrically arranged front and rear chutes are provided at the upper end of the pallet 32. Positioning blocks 340 are installed to slide left and right in the chutes. C-shaped plates 341 are fixedly installed on the opposite surfaces of two front and rear oppositely located positioning blocks 340 and are slidably installed in the corresponding chutes. A first compression spring 342 is fixedly installed between one end of the C-shaped plate 341 away from the corresponding positioning block 340 and the inner wall of the corresponding chute. A pushing member 6 for driving the positioning block 340 to move is provided on the pallet 32.

[0046] As Figure 5 , Figure 6 and Figure 8 shown, the pushing member 6 includes a stop block 60. The stop block 60 is fixedly installed at the upper end of the C-shaped plate 341. The stop block 60 has a right trapezoidal structure with an inclined surface facing the corresponding positioning block 340. Pushing blocks 61 that are in contact and cooperate with the stop block 60 are provided at positions on the pallet 32 corresponding to the C-shaped plates 341 one by one. Two symmetrically arranged front and rear support columns that slide through the pallet 32 are fixedly installed at the lower end of the pushing block 61.

[0047] As Figure 3 , Figure 7 , Figure 8 and Figure 9 shown, the pressing member 8 includes a pressing block 80. Pressing blocks 80 are installed to slide up and down at the opposite ends of two rectangular plates 354. Square plates 81 are provided on the opposite sides of the two pressing blocks 80. A plurality of second tension springs 82 are fixed between the square plates 81 and the corresponding rectangular plates 354. Two sliders 83 that are symmetrically arranged before and after with respect to the pressing block 80 are fixedly installed on the opposite surfaces of the two square plates 81. The sliders 83 slide through the corresponding rectangular plates 354. An actuating component for driving the pressing block 80 to move is provided between the sliders 83 and the pressing block 80.

[0048] As Figure 8 and Figure 9 shown, the actuating component includes an inclined slot 84. Inclined slots 84 that slope downward from top to bottom toward the side close to the corresponding rectangular plate 354 are provided at the front and rear ends of the pressing block 80. Guide posts 85 that are slidably engaged with the corresponding inclined slots 84 are fixedly installed on the sliders 83.

[0049] During specific operation, when the first cylinder 30 pushes the support plate 32 to move upward through the fixing plate 31, the pushing block 61 will contact the lower end of the middle housing. As the support plate 32 moves upward, the gravity of the middle housing will press the pushing block 61 downward and contact the stop block 60, thereby pushing the stop block 60. The stop block 60 will drive the positioning block 340 to move towards the middle housing through the U-shaped plate 341. At this time, the positioning block 340 cannot fully align and limit the middle housing. Then, as the support plate 32 continues to move upward, the middle housing that has not been fully aligned will be pushed upward and away from the roller shaft 21.

[0050] After that, as the rectangular plate 354 moves towards the middle housing, the slider 83 will contact the middle housing. At this time, the slider 83 is blocked and cannot move. Then, as the rectangular plate 354 moves, the rectangular plate 354 will stretch the second tension spring 82 and move. Through the cooperation of the guide post 85 and the inclined groove 84, the pressing block 80 is driven to move downward. The pressing block 80 will contact and press the middle housing to make it close to the support plate 32, thereby further pushing the pushing block 61 to move downward, so as to drive the positioning block 340 to push the middle housing through the stop block 60 and the U-shaped plate 341 to align and limit the middle housing. At the same time, the rectangular plate 354 contacts the middle housing to complete the alignment and fixation of the middle housing.

[0051] As Figure 2 、 Figure 3 、 Figure 4 and Figure 7 As shown in

[0052] As Figure 2 、 Figure 3 [[ID=二十]] Figure 4 ​As shown, the lower pressure member 4 includes a screw rod 40, and the screw rod 40 is rotatably installed on the horizontal section of the bracket 330. The lower end of the screw rod 40 passes through the bracket 330 and is threadedly connected to a pressure plate 41. The front end of the pressure plate 41 slides up and down and is installed on the rear end of the vertical section of the bracket 330. The screw rod 40 is connected to one of the rotating shafts 331 through a belt drive.

[0053] like Figure 2 、 Figure 3 and Figure 7 As shown, the resisting member 5 includes a connecting plate 50, and the front end of the front support plate 20 is slidably installed with the connecting plate 50, a No. 2 compression spring 51 is fixedly installed between the lower end of the connecting plate 50 and the base plate 11, and the right end of the connecting plate 50 is fixedly installed with a circular shaft 52 for supporting the Z-shaped shaft 101.

[0054] During specific operation, after the Z-shaped shaft 101 is installed, under the action of the round shaft 52 and the second compression spring 51, the Z-shaped shaft 101 maintains resistance to the middle shell, and then the stepping motor 333 drives the corresponding rotating shaft 331 to rotate, and the rotating rotating shaft 331 drives the other rotating shaft 331 to rotate through the spur gear 332. The rotation of the two rotating shafts 331 drives the corresponding two L-shaped plates 334 to rotate close to each other through the support plate, and drives the corresponding two pushing plates 335 to rotate close to each other, and the two L The mold plate 334 pushes the stopper 102 through the inclined surface so that the horizontal section of the L-shaped plate 334 is located below the stopper 102 to support the stopper 102. At the same time, the pushing plates 335 are close to each other to squeeze and fix the Z-shaped shaft 101. The rotation of the rotating shaft 331 will also drive the screw rod 40 to rotate through the belt, and the screw rod 40 drives the pressure plate 41 to move downward to squeeze the stopper 102 and the L-shaped plate 334 tightly, thereby fixing the stopper 102 and then performing welding processing.

[0055] After welding is completed, the stepper motor 333 drives the rotating shaft 331 to reverse, and the rotating shaft 331 drives the L-shaped plate 334 away from the stop plate 102, and drives the pushing plate 335 away from the Z-shaped shaft 101. At the same time, the belt drives the screw rod 40 to reverse, and the screw rod 40 drives the pressure plate 41 away from the stop plate 102 to release the fixed limit of the Z-shaped shaft 101 and the stop plate 102 to avoid interfering with the rightward movement of the intermediate shell.
