Description

Technical Field

[0001] This utility model relates to the field of volute processing technology, specifically a turbocharger volute folding lug device. Background Technology

[0002] A turbocharger is essentially an air compressor that increases the intake air volume by compressing air. It uses the inertial force of the exhaust gas from the engine to drive a turbine in the turbine housing. The turbine, in turn, drives a coaxial impeller. The impeller compresses the air supplied by the air filter and forces it into the cylinder. As the engine speed increases, the exhaust gas velocity and turbine speed also increase simultaneously. The impeller then compresses more air into the cylinder. The increased air pressure and density allow for the combustion of more fuel. By increasing the amount of fuel and adjusting the engine speed accordingly, the engine's output power can be increased.

[0003] As an important component of turbochargers, the volute housing has a significant impact on the efficiency and performance of turbochargers. During the production of the volute housing, a folding process is often carried out to meet the overall structure requirements of the volute housing. However, the existing folding process lacks a fixing device, which makes the volute housing prone to popping out during the folding process, resulting in poor practicality.

[0004] The present invention aims to solve the technical problems existing in the prior art. To this end, a turbocharger volute folding lug device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a turbocharger volute folding lug device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A turbocharger volute folding lug device includes a processing table, one end of which is fixedly connected to a drive mechanism, and the processing table is slidably connected to the folding lug device. The drive mechanism extends into the folding lug device and engages with it.

[0008] The processing table is rotatably connected to a transmission mechanism, which meshes with the folding lug device. The processing table is also connected to a fixing mechanism, which cooperates with the transmission mechanism.

[0009] As a further embodiment of this utility model: the driving mechanism includes a driving motor, which is fixedly connected to the processing table. A driving rack is fixedly connected to the contact surface between the driving motor and the processing table. The driving rack passes through the processing table, and the other end of the driving rack extends into the folding lug device and meshes with the folding lug device.

[0010] As a further embodiment of this utility model: the folding ear device includes a pressure block, one end of which is fixedly connected to a guide slider, the guide slider is located in the processing table and slides horizontally in contact with the processing table, a gear tooth is provided on one side of the pressure block, the gear tooth meshes with the transmission mechanism, a slot is provided on the contact surface between the pressure block and the processing table, a slide plate is provided in the slot, the slide plate slides in contact with the pressure block, a guide groove is provided inside the slide plate, a rack is fixedly connected to the slide plate, the rack is located in the guide groove, and the rack meshes with the drive rack.

[0011] As a further embodiment of this utility model: the transmission mechanism includes a rotating shaft, which is rotatably connected to the processing table. The cylindrical surface of the rotating shaft is provided with meshing teeth that mesh with gear teeth. The cylindrical surface of the meshing teeth is provided with guide grooves that cooperate with the fixing device.

[0012] As a further embodiment of this utility model: the fixing device includes a column, which is fixedly connected to the processing table. A fixing plate is slidably connected to the cylindrical surface of the column. The fixing plate is sleeved on the cylindrical surface of the column. A transmission block is fixedly connected to one side of the fixing plate. The transmission block extends into the guide groove and slides in contact with the rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the device is in use, the volute is placed between the column and the rotating shaft, and then the drive motor is started. The drive motor controls the drive rack to rotate. Since the drive rack meshes with the rack, the drive rack drives the rack to move. When the drive rack is at the left and right ends of the rack, the rack drives the slide plate to move along the slot, changing the meshing direction between the rack and the drive rack. That is, the rack performs a reciprocating motion of moving left and right. The rack drives the pressure block to move left and right through the slide plate. The pressure block drives the gear teeth to move. Since the gear teeth mesh with the meshing teeth, the gear teeth drive the rotating shaft to rotate through the meshing teeth. The rotating shaft drives the guide groove to rotate. Since the transmission block is located in the guide groove, and the transmission block slides in contact with the rotating shaft, when the guide groove rotates, the rotating shaft squeezes the transmission block, causing the transmission block to move up and down. That is, when the pressure block moves to fold the volute, the transmission block drives the fixing plate to descend and fix the volute. This device can automatically fix the volute during the folding process, preventing the volute from popping out. Attached Figure Description

The processing table 1 is also connected to a fixing mechanism, which works in conjunction with the transmission mechanism. This device can automatically fix the volute during the folding process, preventing the volute from popping out.

[0022] Please see Figure 1-3 The driving mechanism includes a drive motor 10, which is fixedly connected to the processing table 1. A drive rack 11 is fixedly connected to the contact surface between the drive motor 10 and the processing table 1. The drive rack 11 passes through the processing table 1, and the other end of the drive rack 11 extends into the folding lug device and meshes with the folding lug device. When the drive motor 10 is started, the drive motor 10 controls the drive rack 11 to rotate. Since the drive rack 11 meshes with the rack 16, the drive rack 11 drives the rack 16 to move.

[0023] Please see Figure 1-3The folding device includes a pressure block 4, one end of which is fixedly connected to a guide slider 12. The guide slider 12 is located in the processing table 1 and slides horizontally in contact with the processing table 1.

A guide groove 15 is provided inside the slide plate 14. A rack 16 is fixedly connected to the slide plate 14 and is located in the guide groove 15. The rack 16 meshes with a drive rack 11. When the drive rack 11 is located at the left and right ends of the rack 16, the rack 16 drives the slide plate 14 to move along the slot, changing the meshing direction between the rack 16 and the drive rack 11. That is, the rack 16 performs a reciprocating motion of moving left and right. The rack 16 drives the pressure block 4 to move left and right through the slide plate 14.

[0024] Please see Figure 1-3 The transmission mechanism includes a rotating shaft 7, which is rotatably connected to the processing table 1. The cylindrical surface of the rotating shaft 7 is provided with meshing teeth 9, which mesh with the gear teeth 5. The cylindrical surface of the meshing teeth 9 is provided with a guide groove 8, which cooperates with the fixing device. The pressure block 4 drives the gear teeth 5 to move. Since the gear teeth 5 mesh with the meshing teeth 9, the gear teeth 5 drive the rotating shaft 7 to rotate through the meshing teeth 9, and the rotating shaft 7 drives the guide groove 8 to rotate.

[0025] Please see Figure 1-3 The fixing device includes a column 3, which is fixedly connected to the processing table 1. A fixing plate 2 is slidably connected to the cylindrical surface of the column 3. The fixing plate 2 is sleeved on the cylindrical surface of the column 3.

That is, when the pressure block 4 moves to fold the ear of the volute, the transmission block 6 drives the fixing plate 2 to descend and fix the volute.

[0026] The working principle of this utility model is as follows: When the device is in use, the volute is placed between the column 3 and the rotating shaft 7. Then, the drive motor 10 is started, and the drive motor 10 controls the drive rack 11 to rotate. Since the drive rack 11 meshes with the rack 16, the drive rack 11 drives the rack 16 to move. When the drive rack 11 is located at the left and right ends of the rack 16, the rack 16 drives the slide plate 14 to move along the slot, changing the meshing direction between the rack 16 and the drive rack 11. That is, the rack 16 performs a reciprocating motion of moving left and right. The rack 16 drives the pressure block 4 to move left and right through the slide plate 14. When the pressure block 4 moves, it drives the gear tooth 5 to move. Since the gear tooth 5 meshes with the meshing tooth 9, the gear tooth 5 drives the rotating shaft 7 to rotate through the meshing tooth 9. The rotating shaft 7 drives the guide groove 8 to rotate. Since the transmission block 6 is located in the guide groove 8, and the transmission block 6 slides in contact with the rotating shaft 7, when the guide groove 8 rotates, the rotating shaft 7 squeezes the transmission block 6, causing the transmission block 6 to move up and down. That is, when the pressure block 4 moves to fold the ear of the volute, the transmission block 6 drives the fixing plate 2 to descend and fix the volute. This device can automatically fix the volute during the folding process and prevent the volute from popping out.
