Description

Technical Field

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

[0002] The turbocharger increases the engine's air intake 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 high-speed rotation of the turbine shaft through precision bearings, and 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 Fig.10 as shown).

[0003] The existing tooling used to fix the intermediate housing and the stopper during the welding process of the turbocharger housing usually involves first manually placing the intermediate housing on the workbench, then quickly fixing the intermediate housing with a pneumatic clamp, then installing the Z-axis on the intermediate housing, and then installing the stopper on the Z-axis. A gasket needs to be placed under the stopper to ensure the horizontality of the stopper, and finally the stopper is fixed by pressing down with a pressing piece. However, the above method is cumbersome to operate and is too dependent on manual operation, resulting in low processing efficiency. At the same time, manual operation is difficult to ensure the consistency of subsequent welding quality, and the existing tooling only uses pneumatic clamps and pressing pieces to simply fix the intermediate housing and the stopper, lacks precise positioning and limiting mechanisms, and is difficult to ensure the relative position accuracy of the intermediate housing, the Z-axis, and the stopper, resulting in unstable welding quality, which in turn affects the overall performance and service life of the turbocharger.

Detailed implementation manners

[0034] To make the above - mentioned objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0035] As Figure 1 , Figure 2 and Figure 3 shown, a welding fixture for an automotive turbocharger housing 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 through 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, a fixing plate 31 located below the roller shaft 21 is fixedly installed thereon, and two left-right symmetrical support plates 32 located between the corresponding two roller shafts 21 are fixedly installed at the upper end of the fixing plate 31 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 housing, the bottom plate 11 is provided with a fixing portion 35 for fixing the intermediate housing 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 manually or by a robotic arm, and then the Z-shaped shaft 101 and the stop plate 102 are installed on the intermediate shell manually or by a robotic arm. Then the No. 1 cylinder 30 pushes the fixing plate 31 to move upward, and the fixing 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 centered and fixed by the positioning part 34 and the fixing part 35, and then the Z-shaped shaft 101 and the stop plate 102 are centered and fixed by the limiting part 33, 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, and 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, and 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, and 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 slidably installed on the connecting plate 353. The connecting plate 353 is provided with an extrusion member 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 member 8 that is used to squeeze the intermediate shell and fit tightly against 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 arranged 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 ends of the sliding rods 71 ​​slide through the connecting plate 353, they are jointly fixed with abutment plates 72 that abut against the intermediate shell body. 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, and 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 support plate 32 upward through the fixing plate 31, and the support 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 contact 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 abutting plate 7 2 contacts with the middle shell, at which time the stop plate 72 cannot move further, and then as the connecting plate 353 continues to move, the No. 1 tension spring 73 will be stretched to continue to move toward the middle shell, and the movement of the connecting plate 353 will drive the two rectangular plates 354 to approach each other through the connecting rod 74, and the rectangular plates 354 will squeeze and fix the middle shell, and when the rectangular plates 354 approach the middle shell, they will also squeeze the middle shell downward through the pressing piece 8, and the middle shell squeezed downward will be tightly attached to the supporting plate 32, and at the same time, the middle shell will be further moved to be straightened and limited by the positioning portion 34.

[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 the material.

[0045] As Figure 2 , Figure 5 and Figure 6 shown, the positioning portion 34 includes a chute. Two symmetrically arranged front and rear chutes are provided at the upper end of the support plate 32. Positioning blocks 340 are slidably mounted left and right in the chutes. C-shaped plates 341 slidably mounted in the corresponding chutes are fixedly installed on the opposite faces of two front and rear oppositely positioned positioning blocks 340. 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 movement of the positioning block 340 is provided on the support plate 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 in抵触配合 with the stop block 60 are provided at positions on the support plate 32 corresponding to the C-shaped plates 341 one by one. Two symmetrically arranged front and rear struts that slidably penetrate the support plate 32 are fixedly installed at the lower end of the pushing block 61.

[0047] As Figure 3 , Figure 7 , Figure 8 and Fig. 9 shown, the pressing member 8 includes a pressing block 80. Pressing blocks 80 are slidably mounted 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 plate 81 and the corresponding rectangular plate 354. Two sliders 83 symmetrically arranged front and rear with respect to the pressing block 80 are fixedly installed on the opposite faces of the two square plates 81. The sliders 83 slidably penetrate the corresponding rectangular plates 354. An actuating assembly for driving the movement of the pressing block 80 is provided between the slider 83 and the pressing block 80.

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

[0049] During specific operation, when the first cylinder 30 pushes the support plate 32 to move upward through the fixed 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 squeeze the pushing block 61 downward and make it 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 completely align and limit the middle housing. Then, as the support plate 32 continues to move upward, the middle housing that has not been completely 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 will be driven to move downward. The pressing block 80 will contact and squeeze the middle housing to make it close to the support plate 32, thereby further squeezing 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 and Figure 4As shown, the pressing 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 is slidably installed on the rear end of the vertical section of the bracket 330, and 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 blocking 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 bottom plate 11, and a round shaft 52 for supporting the Z-shaped axis 101 is fixedly installed at the right end of the connecting plate 50.

[0054] During specific operation, after the Z-shaped shaft 101 is installed, the Z-shaped shaft 101 is kept in contact with the middle housing under the action of the round shaft 52 and the second compression spring 51, and then the stepping motor 333 drives the corresponding rotating shaft 331 to rotate, and the rotating rotating shaft 331 drives another rotating shaft 331 to rotate through the spur gear 332, and the rotation of the two rotating shafts 331 drives the corresponding two L-shaped plates 334 to rotate closer through the support plate, and drives the corresponding two pushing plates 335 to rotate closer, and the two L The mold plate 334 pushes the stop plate 102 through the inclined surface, so that the horizontal section of the L-shaped plate 334 is located below the stop plate 102 to support the stop plate 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 stop plate 102 and the L-shaped plate 334 tightly, thereby fixing the stop plate 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.
