[0022] The present invention is described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0023] In the following embodiments, the same or similar numbers throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0024] Figure 1 FIG. 1 is a perspective view of a turbocharger 100 according to the utility model. Figure 2 As shown in its cross-sectional view, the turbocharger 100 is provided with an adjustable nozzle assembly 110 and a shaft assembly 120 .

[0025] See also Figures 3 to 10 The pneumatic actuator assembly device for a turbocharger involved in this application includes a retaining ring tool 11 for installing a shaft retaining ring. The retaining ring tool 11 can be screwed onto the actuator base 13 by thread and pressed internally. The actuator base 13 is provided with an assembly thread 131, so that the mounting groove on the actuator shaft 12 is exposed and the shaft retaining ring 15 is installed, which is convenient to operate. In a specific embodiment, it can be seen from the accompanying drawings that the retaining ring tool 11 has a hexagonal exterior, a through hole is provided on the front side of the retaining ring tool 11, and a convex strip 111 is provided on the inner wall of the retaining ring tool 11. The convex strip 111 is pressed against the internal structure, causing the structure to retreat, so that the mounting groove is exposed and the shaft retaining ring 15 is installed.

[0026] Furthermore, the assembly device in the present application also includes an actuator cover assembly tool 31 for installing the actuator cover 32. The actuator cover assembly tool 31 is provided with an avoidance hole 315 through which the air supply nozzle 328 passes. A matching linkage mating surface is provided between the inner wall of the actuator cover assembly tool 31 and the outer wall of the actuator cover 32. When the actuator cover assembly tool 31 is mounted on the actuator cover 32 and rotated, it can drive the synchronous rotation of the actuator cover 32, thereby facilitating the installation, adjustment, and removal of the actuator cover 32. Specifically, a polygonal inner plane 311 is provided on the inner wall of the actuator cover assembly tool 31, and a matching polygonal outer plane 321 is provided on the outer wall of the actuator cover 32. The inner plane 311 and the outer plane 321 constitute a linkage mating surface that can rotate synchronously.

[0027] The retaining ring fixture 11 and actuator cover assembly fixture 31 described in this application form a pneumatic actuator assembly device, allowing a single person to complete the assembly and disassembly of the pneumatic actuator. Specifically, during operation, the internal components of the pneumatic actuator are sequentially installed. When installing the shaft retaining ring, first install the retaining ring fixture 11 onto the actuator base. As the shaft retaining ring fixture is screwed in, the internal spring is compressed until the shaft retaining ring mounting groove is exposed. The shaft retaining ring is then installed into the tie rod mounting groove and clamped with needle-nose pliers to complete the shaft retaining ring installation.

[0028] When installing the actuator cover, first screw the actuator cover onto the actuator base until it cannot be turned by hand. Then, put on the actuator cover fixture and use a torque wrench to tighten the actuator cover fixture to the designed torque. Remove the actuator cover fixture to complete the assembly. When removing the actuator cover, the actuator cover fixture can be removed. This fixture has been designed with space to avoid the air nozzle, so the actuator cover can be removed without removing the air nozzle. Principle: When tightening the shaft retaining ring fixture, it advances along with the actuator base thread and compresses the spring, making the shaft retaining ring easy to install. The actuator cover fixture uses the internal polygon to cooperate with the outer polygon of the actuator cover to transmit the tightening torque applied by the torque wrench on the actuator cover fixture to the actuator cover, so that the tightening torque of the actuator cover is consistent with the design.

[0029] As described above, the utility model provides a pneumatic actuator assembly device for a turbocharger, which is specifically used for assembling the shaft retaining ring of the pneumatic actuator and the actuator cover. It is easy to operate, can greatly improve the assembly efficiency, save manpower time, and improve the competitiveness of the enterprise's products.

Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field fall within the protection scope of the present invention.
