[0002] As a core component of turbochargers, the machining accuracy and stability of the turbocharger housing are of paramount importance. However, traditional machining fixtures are often designed for specific models or specifications of housings, resulting in poor versatility and adaptability. Furthermore, ensuring accurate positioning and stable clamping of the housing in the fixture during machining, as well as adapting to different heights of the top surface of the housing, are also key issues that urgently need to be addressed in current technology.

[0010] 2. Multiple independently adjustable pressure plates are distributed around the pump housing on the positioning plate. Each pressure plate can be moved up and down along the vertical direction of the screw to independently adjust its height to meet the different height requirements of the top surface of the pump housing. The overall clamping mechanism is used to clamp and fix the pump housing to ensure its stability during processing. Through the cooperation of the sliding mouth and the screw, the distance between the pressure plate and the pump housing can be precisely adjusted, thereby achieving a more precise position fixation between the pressure plate and the pump housing.

[0013] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0014] This application discloses a machining fixture for automotive turbocharger housing products, referring to... Figure 1 and Figure 2The system includes a positioning plate 2, a pump housing 4, a number of inverted T-shaped grooves 5, a number of clamping mechanisms 3, and a number of clamping mechanisms 3 that are configured to cooperate with the inverted T-shaped grooves 5. The number of clamping mechanisms 3 is set according to the size of the pump housing 4 to limit and fix the pump housing 4. The system also includes a number of round rods 6, which are fixedly set in pairs in each inverted T-shaped groove 5. The clamping mechanism 3 includes an inverted T-shaped block 7 that is slidably sleeved on the outer wall of the two round rods 6, a screw 9 that is fixedly set on the top surface of the inverted T-shaped block 7, and a first nut 8 that is threadedly sleeved on the outer wall of the screw 9. The system also includes a base plate 1 that is fixedly set on the bottom surface of the positioning plate 2. The inverted T-shaped block 7 and the inverted T-shaped groove 5 are configured to be slidably fitted. The inverted T-shaped block 7 is slidably moved into the inverted T-shaped groove 5 along the horizontal direction of the round rod 6. By setting the number of inverted T-shaped blocks 7, it can not only be applied to pump housing 4 products of different models and specifications, with strong versatility and adaptability, but also the position of pump housing 4 on the positioning plate 2 can be initially positioned.
[0015] Reference Figure 1 and Figure 3 The pressure plate 12 is movably sleeved on the outer wall of the screw 9. The third nut 11 and the second nut 10 are both threaded on the outer wall of the screw 9 and are respectively located above and below the pressure plate 12. Multiple independently adjustable pressure plates 12 are distributed around the pump housing 4 on the positioning plate 2. Each pressure plate 12 can move up and down along the vertical direction of the screw 9 to independently adjust its height to meet the different height requirements of the top surface of the pump housing 4. The overall clamping mechanism 3 is used to clamp and fix the pump housing 4 to ensure its stability during the processing. The sliding opening 13 is opened through the top surface of the pressure plate 12, the screw 9 passes through the sliding opening 13, and the screw 9 and the sliding opening 13 are configured to slide together. The clamping mechanism 3 also includes a limiting plate 14, which is fixedly set on the top surface of the screw 9. By cooperating with the sliding joint 13 and the screw 9, the distance between the pressure plate 12 and the pump housing 4 can be precisely adjusted, thereby achieving a more precise positional fixation between the pressure plate 12 and the pump housing 4.
[0016] The implementation principle of a processing fixture for a turbocharger housing product for automobiles according to an embodiment of this application is as follows: During the processing, the pump housing 4 to be processed is first placed on the positioning plate 2. The number of fixture mechanisms 3 is set according to the model and specifications of the pump housing 4 and distributed around the pump housing 4. The position of the pump housing 4 on the positioning plate 2 is determined according to the processing requirements. By rotating the first nut 8 towards the positioning plate 2, the fixture mechanism 3 can be fixedly connected to the positioning plate 2. Then, according to the height difference of the top surface of the pump housing 4, each pressure plate 12 moves up and down independently along the vertical direction of the screw 9 to adjust its height so that it fits tightly against the top surface of the pump housing 4. Then, the second nut 10 and the third nut 11 are rotated towards the pressure plate 12 to fix the pressure plate 12 on the screw 9, thereby achieving the tightening and fixing of the pump housing 4.
