Description

Technical Field

[0001] This application relates to the technical field of sub-packing fixtures, and in particular to a general-purpose sub-packing fixture and sub-packing production line for turbochargers. Background Technology

[0002] With the continuous advancement of modern manufacturing technology, the demand for high-precision equipment and mechanical parts is gradually increasing. Turbochargers, as important power transmission devices, are widely used in the automotive, construction machinery, and aerospace industries. By increasing intake pressure, turbochargers effectively increase engine power, thereby improving equipment performance and efficiency. During the production of turbochargers, the precision requirements for each component are extremely high, especially during the assembly process. Any minute error can lead to a decrease in turbocharger performance or even damage to the equipment.

[0003] During the reassembly of turbochargers, ensuring the precise positioning and installation of each component is crucial to guaranteeing product quality and performance. Due to the wide variety of turbocharger models, traditional reassembly processes typically require multiple different toolings to complete the reassembly of different models, leading to cumbersome tooling changes, low production efficiency, and susceptibility to human error. Summary of the Invention

[0004] To address the issue of different tooling requirements for different turbocharger models, this application provides a universal turbocharger assembly fixture and assembly line.

[0005] The technical solution of the universal sub-assembly fixture for turbochargers provided in this application is as follows: A universal sub-assembly fixture for turbochargers includes a tray, a base mounted on the top surface of the tray, a fixing plate mounted on the base, a rotary indexing assembly for controlling the rotation angle of the fixing plate on the base, a clamping assembly for clamping the turbocharger on the fixing plate, a positioning pin fixed on the top surface of the fixing plate, a shaped groove formed on the top surface of the fixing plate, a shaped pin mounted on the fixing plate, the shaped pin including an insert plate inserted into the shaped groove, the insert plate including a middle plate, three limiting plates fixed at equal intervals on the outer periphery of the middle plate, a pin 1 fixed on the top surface of the middle plate, the three limiting plates including mounting plate 1, mounting plate 2, and mounting plate 3, a pin 2 fixed on the top surface of mounting plate 1, and a pin 3 fixed on the top surface of mounting plate 2.

[0006] By adopting the above technical solution, the position of the special-shaped pin is adjusted according to the model of the turbocharger, and then the insert plate is inserted into the special-shaped groove to fix the special-shaped pin to the fixing plate. The turbocharger to be assembled is placed on the fixing plate, so that the positioning pin and the special-shaped pin are aligned with the mounting holes on the turbocharger to achieve the positioning of the turbocharger. Then, the clamping assembly is used to fix the turbocharger to fix the turbocharger to the fixing plate. When it is necessary to replace a different model of turbocharger, only the position of the special-shaped pin needs to be adjusted. The operation is simple and the work efficiency is high.

[0007] Preferably, the bottom surface of the fixing plate has a through groove that communicates with the irregular groove. A handle rod is inserted into the through groove. The top end of the handle rod abuts against the bottom surface of the irregular pin. A handle wheel is fixed to the bottom surface of the handle rod. A spring is sleeved on the outer periphery of the handle rod. The top end of the spring abuts against the fixing plate, and the bottom end of the spring abuts against the handle wheel.

[0008] By adopting the above technical solution, when it is necessary to adjust the irregular pin, first move the handle wheel upward, the handle wheel drives the handle rod to push upward, so that the irregular pin is disengaged from the irregular groove. Then adjust the position of the irregular pin according to the different models of intensifiers. After releasing the handle wheel, the handle wheel returns to its original position under the elastic force of the spring.

[0009] Preferably, the clamping assembly includes a fixed pressure plate fixed to the top surface of the fixed plate, a movable pressure plate slidably mounted on the side of the fixed plate away from the fixed pressure plate, a connecting plate fixed to the bottom surface of the movable pressure plate, the connecting plate slidably mounted below the fixed plate, and a movable pin vertically mounted on the connecting plate, the movable pin being able to abut against the side of the fixed plate away from the movable pressure plate.

[0010] By adopting the above technical solution, after the booster is placed on the top surface of the fixed plate, the movable pressure plate is moved toward the direction of the fixed pressure plate, and then the movable pin is moved upward so that the movable pin abuts against the side of the fixed plate, so that the movable pressure plate cannot move away from the fixed pressure plate, and the movable pressure plate clamps and fixes the booster.

[0011] Preferably, a threaded shaft is fixedly installed on the top surface of the connecting plate, the movable pin is slidably installed in the threaded shaft along the vertical direction, and a second spring is installed on the bottom surface of the movable pin, the bottom end of the second spring abutting against the inner bottom surface of the threaded shaft.

[0012] By adopting the above technical solution, the movable pressure plate is moved toward the direction closer to the turbocharger, so that the movable pin moves to the side of the fixed plate away from the movable pressure plate. Under the elastic force of the second spring, the movable pin moves upward and abuts against the side of the fixed plate, so that the movable pressure plate always abuts against the turbocharger when the fixed plate rotates.

[0013] Preferably, the outer circumferential surface of the threaded shaft is provided with a connecting groove, and a moving rod is fixedly inserted through the bottom of the moving pin. The moving rod slides vertically with the threaded shaft through the connecting groove. A handle sleeve is fitted on the outer circumference of the threaded shaft, and a through hole for inserting the moving rod is provided on the outer circumferential surface of the handle sleeve.

[0014] By adopting the above technical solution, the handle sleeve is pulled down, which drives the moving rod to move down, and the moving rod drives the moving pin to move down, contacting the limit of the moving pressure plate, so as to facilitate the replacement of the booster.

[0015] Preferably, the rotary indexing assembly includes a fixed disk fixed to the base, a rotary disk rotatably mounted on the side of the fixed disk, a fixed plate fixed to the side of the rotary disk away from the fixed disk, three positioning sleeves fixed on the side of the rotary disk near the fixed disk, and an indexing pin for inserting into the positioning sleeves installed on the fixed disk.

[0016] By adopting the above technical solution, the insertion and cooperation of the three positioning sleeves and the indexing pin can realize the positioning of the fixed plate in a horizontal state, the rotation of the fixed plate clockwise by 90° and the rotation of the fixed plate counterclockwise by 60°, so as to meet the assembly operation of different models of turbochargers at different angles.

[0017] Preferably, the fixed disk has an arc-shaped groove on its side near the rotating disk, and a limiting post is fixed on the side of the rotating disk near the fixed disk. The limiting post slides and engages with the fixed disk through the arc-shaped groove.

[0018] By adopting the above technical solution, the limiting post can slide in the arc groove of the fixed plate. When the rotating plate rotates 90° clockwise or 60° counterclockwise, the limiting post is blocked by the arc surfaces at both ends of the arc groove, preventing the fixed plate from overturning.

[0019] Preferably, a reflector is fixed to the outer peripheral surface of the rotating disk, and the reflector cooperates with a diffuse reflection sensor on the production line.

[0020] By adopting the above technical solution, the reflector works in conjunction with the diffuse reflection sensor on the production line to detect when the booster on the fixed plate is flipped into place.

[0021] Preferably, the tray includes a supporting aluminum plate, and a sensor is fixed on the top surface of the supporting aluminum plate. The sensor is connected to a sensor on the side of the production line.

[0022] By adopting the above technical solution, the sensing element is connected to the side sensor signal of the production line for fixture positioning detection. A general-purpose turbocharger packaging line includes an upper working layer and a lower recycling layer, both of which are equipped with high-speed conveyors for transporting jigs.

[0023] By adopting the above technical solution, the fixture can circulate on the production line, with the upper layer being the working layer and the lower layer being the recycling layer, so as to achieve a asynchronous parallel production layout. The sub-assembly of the booster pump is independent of the engine assembly line, so that the staff can make product quantity matching in advance.

[0024] In summary, this application includes at least one of the following beneficial technical effects: Adjust the position of the special-shaped pin according to the model of the turbocharger, then insert the insert plate into the special-shaped groove to fix the special-shaped pin to the fixing plate. Place the turbocharger to be assembled on the fixing plate, align the positioning pin and the special-shaped pin with the mounting holes on the turbocharger to achieve positioning of the turbocharger. Then use the clamping assembly to fix the turbocharger to fix the turbocharger to the fixing plate. When it is necessary to replace the turbocharger with a different model, you only need to adjust the position of the special-shaped pin. The operation is simple and the work efficiency is high. After placing the booster on the top surface of the fixed plate, move the movable pressure plate toward the direction of the fixed pressure plate, and then move the movable pin upward so that the movable pin abuts against the side of the fixed plate, so that the movable pressure plate cannot move away from the fixed pressure plate, and the movable pressure plate clamps and fixes the booster. Move the movable pressure plate toward the direction of the supercharger, so that the movable pin moves to the side of the fixed plate away from the movable pressure plate. Under the elastic force of the second spring, the movable pin moves upward and abuts against the side of the fixed plate, so that the movable pressure plate always abuts against the supercharger when the fixed plate rotates.

[0036] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0037] This application discloses a universal sub-assembly fixture and sub-assembly line for turbochargers. (Refer to...) Figure 1 The universal sub-assembly fixture for turbochargers includes a tray 1, with a base 2 fixed to the top surface of the tray 1. The tray 1 includes a supporting aluminum plate 11, with a sensor 12 fixed to the top surface of the supporting aluminum plate 11. The sensor 12 is connected to a sensor signal on the side of the production line for fixture positioning detection. A fixing plate 3 is mounted on the base 2, and a rotary indexing assembly 4 is provided on the base 2 to control the rotation angle of the fixing plate 3. A clamping assembly 6 for holding the turbocharger is provided on the fixing plate 3.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The rotary indexing assembly 4 includes a fixed disk 41 fixed to the base 2, a rotary disk 42 rotatably mounted on the side of the fixed disk 41, and a fixed plate 3 fixed to the side of the rotary disk 42 away from the fixed disk 41. A reflector 43 is fixed to the outer circumferential surface of the rotary disk 42. The reflector 43 cooperates with a diffuse reflection sensor on the production line for detecting the intensifier flipped into position on the fixed plate 3. Three positioning sleeves 44 are fixed to the side of the rotary disk 42 near the fixed disk 41, and an indexing pin 45 for inserting into the positioning sleeves 44 is installed on the fixed disk 41. An arc-shaped groove 46 is formed on the side of the fixed disk 41 near the rotary disk 42, and a limit post 47 is fixed to the side of the rotary disk 42 near the fixed disk 41. The limit post 47 slides and engages with the fixed disk 41 through the arc-shaped groove 46.

[0039] The three positioning sleeves 44 and the indexing pins 45 are engaged to enable the positioning of the fixed plate 3 in a horizontal state, the rotation of the fixed plate 3 clockwise by 90° and the rotation of the fixed plate 3 counterclockwise by 60°, so as to meet the assembly operations of different models of turbochargers at different angles. When the turbocharger needs to be rotated, the operator first pulls out the indexing pins 45 and rotates the rotating disk 42. When the rotating disk 42 rotates to the required rotation angle, the indexing pins 45 automatically push into the positioning sleeves 44 under the elastic force of their own return springs. The limiting post 47 can slide in the arc groove 46 of the fixed disk 41. When the rotating disk 42 rotates 90° clockwise or 60° counterclockwise, the limiting post 47 is blocked by the arc surfaces at both ends of the arc groove 46 to prevent the fixed plate 3 from being rotated excessively.

[0040] Reference Figure 4 and Figure 5 A positioning pin 31 is fixed to the top surface of the fixing plate 3, and the positioning pin 31 can be inserted into the mounting hole on the turbocharger. A shaped groove 35 is formed on the top surface of the fixing plate 3, and a shaped pin 32 is installed on the fixing plate 3. The shaped pin 32 includes an insert plate 33 inserted into the shaped groove 35. The insert plate 33 includes a middle plate 331, and three limiting plates 332 are fixed at equal intervals around the outer periphery of the middle plate 331, with a 120° angle between adjacent limiting plates 332. A first pin 333 is fixed to the top surface of the middle plate 331. The three limiting plates 332 include a first mounting plate 3321, a second mounting plate 3322, and a third mounting plate 3323. A second pin 334 is fixed to the top surface of the first mounting plate 3321, and a third pin 335 is fixed to the top surface of the second mounting plate 3322.

[0041] Rotate the shaped pin 32 clockwise or counterclockwise by 120° depending on the model of the turbocharger, and then reinsert the shaped pin 32 into the shaped groove 35. This will adjust the position of the shaped pin 32 so that it can be inserted into the mounting hole of the corresponding model of turbocharger, thereby achieving the positioning of different models of turbochargers.

[0042] Reference Figure 6 and Figure 7 The bottom surface of the fixing plate 3 has a through groove 34 that communicates with the irregular groove 35. A handle rod 5 passes through the through groove 34. The handle rod 5 includes a middle rod 51, and a limiting ring 52 is fitted around the outer periphery of the middle rod 51. The limiting ring 52 is located inside the irregular groove 35, and the outer diameter of the limiting ring 52 is larger than the inner diameter of the through groove 34. An abutment post 53 is fixed to the top of the middle rod 51, and a slot 3311 for inserting the abutment post 53 is opened on the bottom surface of the intermediate plate 331. A handle wheel 54 is fixed to the bottom end of the middle rod 51, and a spring 55 is fitted around the outer periphery of the middle rod 51. The top end of the spring 55 abuts against the bottom surface of the fixing plate 3, and the bottom end of the spring 55 abuts against the handle wheel 54.

[0043] When the shaped pin 32 needs to be adjusted, first move the handle wheel 54 upward. The handle wheel 54 drives the handle rod 5 to push upward, so that the shaped pin 32 is disengaged from the shaped groove 35. Then adjust the position of the shaped pin 32 according to the different models of the booster. After releasing the handle wheel 54, the handle wheel 54 returns to its original position under the elastic force of the spring 55.

[0044] Reference Figure 4 and Figure 8 The clamping assembly 6 includes a fixed pressure plate 61 fixed to the top surface of the fixed plate 3, and a movable pressure plate 62 slidably mounted on the side of the fixed plate 3 away from the fixed pressure plate 61. A connecting plate 63 is fixed to the bottom surface of the movable pressure plate 62, and the connecting plate 63 is slidably mounted below the fixed plate 3. Two guide plates 64 are fixed to the bottom surface of the fixed plate 3, and guide grooves 65 are respectively opened on the opposite inner sides of the two guide plates 64. The connecting plate 63 is slidably connected to the fixed plate 3 through the guide grooves 65.

[0045] Reference Figure 8 and Figure 9 A threaded shaft 7 is fixedly mounted on the top surface of the connecting plate 63. A movable pin 71 is vertically slidable inside the threaded shaft 7, and the movable pin 71 abuts against the side of the fixed plate 3 away from the movable pressure plate 62. A second spring 72 is mounted on the bottom surface of the movable pin 71, and the bottom end of the second spring 72 abuts against the inner bottom surface of the threaded shaft 7. A connecting groove 73 is opened on the outer circumferential surface of the threaded shaft 7, and a movable rod 74 is fixedly mounted on the bottom of the movable pin 71. The movable rod 74 slides vertically with the threaded shaft 7 through the connecting groove 73. A handle sleeve 75 is fitted on the outer circumference of the threaded shaft 7, and a through hole 76 for inserting the movable rod 74 is opened on the outer circumferential surface of the handle sleeve 75.

[0046] Move the movable pressure plate 62 toward the direction of the booster, so that the movable pin 71 moves to the side of the fixed plate 3 away from the movable pressure plate 62. The movable pin 71 moves upward under the elastic force of the spring 72 and abuts against the side of the fixed plate 3, so that the movable pressure plate 62 always abuts against the booster when the fixed plate 3 rotates. Pull the handle sleeve 75 down, and the handle sleeve 75 drives the movable rod 74 to move downward. The movable rod 74 drives the movable pin 71 to move downward and contact the limit of the movable pressure plate 62, so as to facilitate the replacement of the booster.

[0047] The implementation principle of a universal sub-assembly fixture for turbochargers in this application embodiment is as follows: Adjust the position of the special-shaped pin 32 according to the model of the turbocharger, and then insert the special-shaped pin 32 into the special-shaped groove 35 so that the special-shaped pin 32 is fixed to the fixing plate 3. Place the turbocharger to be assembled on the fixing plate 3 so that the positioning pin 31 and the special-shaped pin 32 are aligned with the mounting holes on the turbocharger to achieve positioning of the turbocharger. Then use the clamping assembly 6 to fix the turbocharger so that the turbocharger is fixed to the fixing plate 3. When it is necessary to replace a different model of turbocharger, only the position of the special-shaped pin 32 needs to be adjusted. The operation is simple and the work efficiency is high.

[0048] Reference Figure 10 A general-purpose turbocharger packaging line includes an upper working layer 8 and a lower recycling layer 81, both of which are equipped with a double-speed chain 82 for transporting fixtures.

[0049] The fixtures can circulate on the production line, with the upper layer being the working layer and the lower layer being the recycling layer, to achieve a asynchronous parallel production layout. The sub-assembly of the booster pump is independent of the engine assembly line, so that the staff can match the product quantities in advance.
