Description

Technical Field

[0001] The utility model relates to the technical field of turbocharger housing production and processing, and specifically relates to a turbocharger housing assembly device. Background Technique

[0002] The assembly of the turbocharger housing is an important technological process in turbo machinery manufacturing. As the outer shell of the turbocharger, the good assembly quality of the turbocharger housing directly affects the performance and reliability of the entire turbocharger. The press-fitting assembly of the turbocharger housing requires strict process control and technical requirements. During the assembly process, it is necessary to ensure that the internal space and structure of the turbocharger housing meet the design requirements to accommodate other key components of the turbocharger, such as impellers, bearings, and seals. In the prior art, the assembly of the turbocharger housing is manually aligned and pressed by a hydraulic press. On the one hand, the production efficiency is extremely low, and on the other hand, the alignment deviation of the turbocharger housing during manual operation is relatively large. Therefore, a device for efficiently assembling the turbocharger housing is needed.

[0003] The utility model with the authorization announcement number CN218891426U discloses a turbo assembly device. In this utility model, the turbo is placed in the turbo positioning device, and the cylinder ram applies pressure to the surface of the turbocharger housing, thereby completing the assembly of the turbocharger housing and improving the assembly efficiency of the turbocharger housing.

[0004] The above device can achieve the purpose of assembling the turbocharger housing. However, when applying pressure to the turbocharger housing, there is only one force application point, and the surface height of the turbocharger housing is not consistent. When applying pressure, the situation of the turbocharger housing shifting easily occurs, affecting the assembly quality of the turbocharger housing. Therefore, a turbocharger housing assembly device with efficient multi-point pressure application is needed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a turbocharger housing assembly device to solve the problems raised in the above background technique.

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

[0007] A turbocharger housing assembly device includes a first bracket. A linear guide rail mechanism is relatively fixedly arranged above the first bracket. A turbo positioning seat is arranged above the linear guide rail mechanism. A second bracket is fixedly arranged outside the linear guide rail mechanism above the first bracket. A fixed seat is fixedly arranged inside the second bracket above the first bracket. A hydraulic cylinder is fixedly arranged below the second bracket. The end of the telescopic shaft of the hydraulic cylinder is fixedly provided with a moving seat. A plurality of pressing devices are fixedly arranged below the moving seat.

[0008] As a further scheme of the utility model: A positioner is fixedly arranged in the middle of the front end face of the fixed seat. A laser positioning sensor cooperating with the positioner is fixedly arranged on the rear end face of the turbo positioning seat.

[0009] As a further solution of the present utility model: a turbine positioning groove is provided in the turbine positioning seat, and a turbine positioning hole is provided in the turbine positioning groove.

[0010] As a further solution of the present utility model: the pressing device includes an electric push rod, a pressure sensor is fixedly arranged at the end of the output shaft of the electric push rod, and a rubber force-applying block is fixedly arranged below the pressure sensor.

[0011] As a further solution of the present utility model: the linear guide rail mechanism is provided with a locking mechanism.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Using the linear guide rail mechanism as a power source, the turbine positioning seat moves on the linear guide rail mechanism, and the laser positioning sensor communicates with the positioner, which is convenient for positioning the turbine positioning seat and facilitating the next operation of press-fitting and assembling the turbine housing, improving the assembly efficiency of the device. The turbine positioning groove and the turbine positioning hole facilitate the operator to quickly place the turbine housing.

[0014] 2. Through multiple pressing devices, the end of the output is tightly attached to the surface of the turbine housing to be assembled (the surface of the turbine housing is irregular), which is convenient for the hydraulic cylinder to apply pressure synchronously at multiple points through the multiple pressing devices, avoiding the uneven force application in the state of only one force application point, improving the quality of the press-fitting of the turbine housing, and improving the product qualification rate.

[0015] 3. By adjusting the telescopic length of the electric push rod, it is convenient for the rubber force-applying block to be tightly attached to the surface of the turbine housing. The pressure sensor monitors whether the rubber force-applying block is tightly attached to the surface of the turbine housing. When the pressure sensor generates a pressure change, it means it is tightly attached, improving the press-fitting and assembly efficiency of the turbine housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Embodiment

[0024] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, a turbine housing assembly device includes a first bracket 1. A linear guide mechanism 2 is relatively fixedly arranged above the first bracket 1. The linear guide mechanism 2 is provided with a locking mechanism. A turbine positioning seat 5 is arranged above the linear guide mechanism 2. A turbine positioning groove 51 is formed in the turbine positioning seat 5, and a turbine positioning hole 52 is formed in the turbine positioning groove 51. A second bracket 3 is fixedly arranged outside the linear guide mechanism 2 above the first bracket 1. A fixed seat 4 is fixedly arranged inside the second bracket 3 above the first bracket 1. A positioner 10 is fixedly arranged in the middle of the front end face of the fixed seat 4. A laser positioning sensor 9 cooperating with the positioner 10 is fixedly arranged on the rear end face of the turbine positioning seat 5. Using the linear guide mechanism 2 as a power source, the turbine positioning seat 5 moves on the linear guide mechanism 2. The laser positioning sensor 9 and the positioner 10 communicate with each other, facilitating the positioning of the turbine positioning seat 5, facilitating the next step of press-fitting and assembling the turbine housing, improving the assembly efficiency of the device. The turbine positioning groove 51 and the turbine positioning hole 52 facilitate the operator to quickly place the turbine housing.

[0025] A hydraulic cylinder 6 is fixedly arranged below the second bracket 3. A moving seat 7 is fixedly arranged at the end of the telescopic shaft of the hydraulic cylinder 6. A plurality of tightening devices 8 are fixedly arranged below the moving seat 7. The output ends of the plurality of tightening devices 8 are made to be in close contact with the surface of the turbine housing to be assembled (the surface of the turbine housing is irregular), facilitating the hydraulic cylinder 6 to apply pressure synchronously at multiple points through the plurality of tightening devices 8, avoiding the situation of uneven force application in the state of only one force application point, improving the quality of press-fitting the turbine housing, and improving the product qualification rate.

[0026] The said pressing device 8 includes an electric push rod 81. The end of the output shaft of the electric push rod 81 is fixedly provided with a pressure sensor 82. Below the pressure sensor 82, a rubber force-applying block 83 is fixedly provided. By adjusting the telescopic length of the electric push rod 81, it is convenient for the rubber force-applying block 83 to be in close contact with the surface of the turbine housing. The pressure sensor 82 monitors whether the rubber force-applying block 83 is in close contact with the surface of the turbine housing. When there is a pressure change in the pressure sensor 82, it means close contact, which improves the pressing and assembling efficiency of the turbine housing.

[0027] When the device is in use, the operator places the turbine housing to be assembled in the turbine positioning groove 51 of the turbine positioning seat 5. Then start the linear guide mechanism 2. When the laser positioning sensor 9 and the positioner 10 communicate, turn off the linear guide mechanism 2, and the locking mechanism in the linear guide mechanism 2 locks. Start the electric push rod 81 to make the rubber force-applying block 83 contact the surface of the turbine housing to be assembled. When the pressure sensor 82 detects a pressure change, the rubber force-applying block 83 is in close contact with the surface of the turbine housing. Turn off the electric push rod 81 and start the hydraulic cylinder 6 to apply pressure to the turbine housing to be assembled, thereby completing the pressing and assembling of the turbine housing. Then reset the hydraulic cylinder 6 and the electric push rod 81. Start the linear guide mechanism 2 to feed the assembled turbine housing to the end station. After taking away the assembled turbine housing, the linear guide mechanism 2 drives the turbine positioning seat 5 back to the initial position.
