[0002] The thrust chamber nozzle is an important part of a rocket engine. The thrust chamber nozzle is composed of two conical tubes, one of which is a contraction tube and the other is an expansion tube. It is the most commonly used component in rocket engines and aeroengines. During the processing of the thrust chamber nozzle, it is necessary to stably clamp the nozzle to ensure the processing quality and efficiency. The existing clamping mechanisms are usually complex in structure and unstable in clamping, and cannot meet the processing requirements of nozzles with different sizes and shapes.

[0003] The existing technology has the following problems:

[0004] 1. In the actual use process of the existing clamping mechanism, the thrust chamber nozzle is manually clamped and fixed by using a limiting rod in cooperation with a bolt.

[0005] 2. When the existing thrust chamber nozzle is placed, the thrust chamber nozzle is hoisted onto the processing platform by a machine, and then the thrust chamber nozzle is moved to a suitable position manually. This existing operation method increases the manual output, and when the thrust chamber nozzle is moved, the bottom end of the thrust chamber nozzle will be worn, thus affecting the finished product quality of the thrust chamber nozzle. Therefore, a clamping mechanism for thrust chamber nozzle processing is proposed. Content of the Utility Model

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4, in this implementation: A clamping mechanism for machining a thrust chamber nozzle includes a device main body 1.

A limit hole 11 is provided on one side of the chute 8;

[0026] The hydraulic pump 6 includes a hydraulic rod 61, a hinge block 62, a claw 63 and an anti-slip pad 630. The hydraulic rod 61 is fixedly installed at the output end of the hydraulic pump 6. The hinge block 62 is installed on one side of the hydraulic rod 61. The claw 63 is fixedly installed on one side of the hinge block 62;

[0027] The chute 8 includes a slider 81 and a ball 82. The slider 81 is installed inside the slider 81. The ball 82 is embedded inside the chute 8.

[0028] In this embodiment, the number of claws 63 is two groups. The claws 63 are symmetrically installed on both sides of the thrust chamber nozzle main body 7. By setting two groups of claws 63, the fixing effect on the thrust chamber nozzle main body 7 can be improved; the hinge block 62 is fixedly installed outside the claw 63. The hinge block 62 is hinged to one end of the hydraulic rod 61. By using the hinge block 62, the claw 63 can be adjusted adaptively in angle, thereby increasing the contact area between the claw 63 and the thrust chamber nozzle main body 7; the anti-slip pad 630 is made of rubber. The anti-slip pad 630 is fixedly installed on the inner surface of the claw 63. By using the anti-slip pad 630, the friction between the claw 63 and the thrust chamber nozzle main body 7 can be increased, avoiding the situation of sliding of the claw 63 during the clamping process of the thrust chamber nozzle main body 7, thereby improving the use stability of the claw 63; the number of sliders 81 is two groups. The sliders 81 are symmetrically installed on the lower surface of the machining platform 9. The sliders 81 are slidably connected to the chute 8. By using the cooperation of the chute 8 and the slider 81, the position of the machining platform 9 can be adjusted, thereby using the machining platform 9 to assist the operator to finely adjust the position of the thrust chamber nozzle main body 7 again; the number of balls 82 is several groups. The balls 82 are equidistantly embedded in the inner wall of the chute 8. The balls 82 are movably connected to the inner wall of the chute 8. By using the balls 82, the friction between the chute 8 and the slider 81 can be reduced, thereby facilitating the movement of the slider 81; one end of the limit bolt 10 penetrates through the inner wall of the machining platform 9 and extends inside the limit hole 11. The limit bolt 10 is movably connected to the limit hole 11. By using the cooperation of the limit bolt 10 and the limit hole 11, the machining platform 9 can be limited, avoiding the situation of self-movement during its use, thereby improving the use stability of the machining platform 9.

[0029] Working principle and usage process of the utility model: When the operator uses the device main body 1, after hoisting the thrust chamber nozzle main body 7 to the upper surface of the processing platform 9 by machinery, when making fine adjustments to the position of the thrust chamber nozzle main body 7, the cooperation of the sliding groove 8 and the slider 81 can be used to adjust the position of the processing platform 9, so as to assist the operator in making fine adjustments to the position of the thrust chamber nozzle main body 7 again by using the processing platform 9. Then, the ball 82 can be used to reduce the friction between the sliding groove 8 and the slider 81, thus facilitating the movement of the slider 81. In this way, the mobility of the thrust chamber nozzle main body 7 is improved, and the damage suffered by the thrust chamber nozzle main body 7 during movement is reduced, improving the usage effect of the device main body 1. Then, after moving the thrust chamber nozzle main body 7 to a suitable position, the control pump 5 is started through the control panel 2, and the hydraulic pump 6 is pressurized by the cooperation of the control pump 5 and the connecting oil pipe 51, so as to adjust the position of the claw 63 by using the hydraulic rod 61. Then, the thrust chamber nozzle main body 7 is clamped and fixed by using the claw 63, and the angle of the claw 63 can be adaptively adjusted by using the hinge block 62, so as to increase the contact area between the claw 63 and the thrust chamber nozzle main body 7, improving the clamping effect of the claw 63 on the thrust chamber nozzle main body 7. And the anti-slip pad 630 can be used to increase the friction between the claw 63 and the thrust chamber nozzle main body 7, avoiding the situation of sliding of the claw 63 during the clamping process of the thrust chamber nozzle main body 7, thus improving the usage stability of the claw 63.
