[0031] The following is a further detailed description of this application in combination with the attached Figure 1 - attached Figure 4 drawings.

[0032] A clamping fixture for the inner ring of a snap ring of a ship torque power meter, referring to Figure 1, including a fixture disc 1, a snap ring 2 to be machined is located on the fixture disc 1. There are fixed protrusions 11 on the outside of the fixture disc 1, and the snap ring 2 is placed within the fixed protrusions 11. Threaded holes 31 are provided on the fixed protrusions 11, and fixing screws 3 are installed. At the same time, clamping blocks 4 are installed inside the fixing screws 3. By tightening the fixing screws 3, the clamping blocks 4 are pressed tightly against the snap ring 2 for fixation. At the same time, a support protrusion 41 is provided on one side of the clamping block 4, which can reduce the screwing-in amount of the fixing screw 3, simplify the installation process, and also enable the other side of the clamping block 4 to firmly press against the snap ring 2. A soft rubber gasket 42 is installed at the end of the clamping block 4 away from the support protrusion 41. The material of the soft rubber gasket 42 is rubber. The soft rubber gasket 42 is fixed by inserting fixing protrusions 421 into insertion slots 43. The soft rubber gasket 42 increases the friction between the clamping block 4 and the snap ring 2, thereby reducing the movement of the snap ring 2 and making the snap ring 2 more firmly fixed. At the same time, the soft rubber gasket 42 can also reduce the wear between the clamping block 4 and the snap ring 2.

[0033] Refer to Figure 3 , a fixture platform 111 is provided at the position corresponding to the clamping block 4 on the outside of the fixture disc 1. The fixture platform 111 is for the support protrusion 41 to be placed, preventing the support protrusion 41 from slipping out of the edge of the fixed protrusion 11. At the same time, since the fixture platform 111 needs to bear force for support, a reinforcing rib 112 is provided between the fixture platform 111 and the fixed protrusion 11, thereby improving the force-bearing capacity of the fixture platform 111 and increasing the service life of the fixture platform 111.

[0034] Refer to Figure 4 , a positioning protrusion 5 is provided on the inner side of the fixture disc 1. A positioning groove 6 is formed between the positioning protrusion 5 and the fixed protrusion 11. The snap ring 2 is placed in the positioning groove 6. The positioning groove 6 can limit the movement of the snap ring 2 during the machining process. At the same time, a soft rubber washer 51 is installed on the outer side wall of the positioning protrusion 5. The material of the soft rubber washer 51 is rubber, which can further limit the movement of the snap ring 2 in the positioning groove 6. And the soft rubber washer 51 can increase the friction between the snap ring 2 and the positioning protrusion 5, so that the snap ring 2 will not easily slip out of the positioning groove 6. At the same time, it can also reduce the wear between the snap ring 2 and the positioning protrusion 5 and increase the service life of the fixture.

[0035] The implementation principle of the embodiment of this application is:

[0036] Place the snap ring 2 to be processed in the positioning groove 6 along the fixed protrusion 11 and the positioning protrusion 5 to restrict the snap ring 2. The inner side wall of the snap ring 2 is attached to the soft rubber washer 51 installed on the outer side of the positioning protrusion 5, further restricting the movement of the snap ring 2 through the soft rubber washer 51 and reducing the wear amount between the snap ring 2 and the positioning protrusion 5. Subsequently, tighten the fixing screw 3 installed on the fixed protrusion 11. The fixing screw 3 drives the clamping block 4 to press tightly on the snap ring 2. The supporting protrusion 41 provided on the clamping block 4 abuts against the fixture table 111, making the other end of the fixture block 4 firmly press on the snap ring 2. At the same time, at one end of the clamping block 4 away from the supporting protrusion 41, a soft rubber gasket 42 is installed through the insertion groove 43, increasing the friction force between the clamping block 4 and the snap ring 2 and reducing the wear between the clamping block 4 and the snap ring 2, thereby increasing the service life. Moreover, by using the cooperation of the insertion protrusion 421 and the insertion groove 43, it is also convenient to replace the soft rubber gasket 42. At the same time, a reinforcing rib 112 is provided below the fixture table 111, which plays a role in strengthening the force on the fixture table 111 and preventing the fixture table 111 from being easily damaged.
