Description

Technical Field

[0001] The invention relates to the technical field of mechanisms for preventing an engine tail nozzle from being deformed during heat treatment, and in particular to a mechanism for preventing an engine tail nozzle from being deformed during heat treatment. Background Art

[0002] The mechanism for preventing deformation during heat treatment is a mechanism used in the production and processing of the engine tail nozzle to reduce or eliminate the deformation of the engine tail nozzle caused by temperature changes, uneven stress distribution and other factors during the heat treatment process.

[0003] During the production heat treatment process of the engine tail nozzle, an internal support tool is used to support the bottom of the engine tail nozzle to prevent deformation due to gravity. Due to the different models of engine tail nozzles produced, the inner wall size of the bottom will also be different, but the support block size of the support tool is usually fixed, resulting in that in actual use, a support ring of corresponding size is generally customized according to the size of the bottom of the engine tail nozzle that needs to be supported to support and reinforce the inside. This operation will increase the processing cost of the heat treatment, and when heat treating engine tail nozzles of different models and sizes, it is necessary to first remove the previous support ring and then replace it with a support ring of corresponding size for support, which results in more preparation steps before processing and reduces processing efficiency.

[0030] Working principle: during the production heat treatment process of the engine tail nozzle, the bottom of the engine tail nozzle is supported by an internal support tool to prevent deformation due to gravity. According to the size of the bottom of the engine tail nozzle that needs heat treatment, after the bottom of the engine tail nozzle is sleeved on the outer surface of a plurality of first support blocks 29, the dual-axis motor 22 is started to drive the threaded rod 23 to rotate. Under the limiting action of the limiting rod 220, the screw hole block 24 and the groove block 25 can be driven to move downward, and one end of the connecting rod 26 is squeezed and pushed so that its two ends are respectively rotated to a certain angle in the inner wall of the groove block 25 and between the two protrusions 27.

By adjusting the plurality of first support blocks 29 The bottom of an engine tail nozzle of any size can be supported and reinforced, which is easy to operate and use, improves processing efficiency, and reduces the cost of customized support rings. When one side of the first support block 29 is abutted and supported on the inner wall of the engine tail nozzle, the inner wall of the engine tail nozzle will squeeze the abutment block 213, causing it to slide into the circular hole 210, driving the spring 212 to shrink, and one end of the abutment block 213 slides toward one end in the inner wall of the sliding hole frame 211, pushing one end of the elastic rotating rod 215 to rotate to a certain angle in the inner wall of the U-shaped block 214, causing the torsion spring 217 to deform, driving the other end to push the second support block 216 to move toward the inner wall of the engine tail nozzle, and performing secondary support and reinforcement on the inner wall of the engine tail nozzle. In this way, secondary support can be performed according to the shape of the inner wall at the bottom and the inner wall at the upper end of the engine tail nozzle, thereby increasing the support area, reducing the probability of deformation during heat treatment, and improving the quality of the processed product.

[0031] When the engine tail nozzle is supported and limited and then heat treated, the other output end of the dual-axis motor 22 can be started to drive the circular shaft 31 to rotate, and then the gear 32 can be driven to rotate on one side of the base 1 under the transmission of the belt 33, and the gear ring block 34 and the disc 4 can be driven to rotate on one side of the base 1, and at the same time, a plurality of first support blocks 29 and the supported and reinforced engine tail nozzle are driven to rotate on the outer surface of the screw hole block 24 with the help of the groove block 25, so that it can rotate at a uniform speed during the support and reinforcement process, so that the outer surface of the engine tail nozzle is heated more evenly, thereby reducing the probability of deformation and improving the processing effect and quality.
