Description

Technical Field

[0001] The utility model relates to the technical field of nozzles with special-shaped structures, and specifically relates to a processing tooling for nozzles with special-shaped structures. Background Technique

[0002] A nozzle is an important mechanical component and is widely used in various fields, such as rocket engines, impeller-type power machines, etc. A nozzle, also known as an exhaust nozzle, thrust nozzle or tail nozzle, is a device that accelerates the airflow by changing the geometric shape of the inner wall of the pipe section. It is mainly used to convert the pressure energy and thermal energy of high-pressure fluid into kinetic energy, so as to achieve high-speed jetting and thrust generation. A nozzle with a special-shaped structure refers to a nozzle that accelerates the airflow by changing the geometric shape of the inner wall of the pipe section and has a non-standard or special design. To ensure the stability of the nozzle with a special-shaped structure during processing, a processing tooling is required.

[0003] Common processing toolings for nozzles with special-shaped structures are usually composed of structures such as a fixed seat, a support block, a limiting device and other auxiliary components. After placing the nozzle with a special-shaped structure on the processing table, the limiting device is connected to the support block, and the support block is installed on the fixed seat. The limiting device drives the support block and moves along the fixed seat under the action of the auxiliary components, and closely fits with the outer surface of the nozzle with a special-shaped structure.

[0004] Traditional nozzle processing toolings are used in cooperation with threaded rods and clamping plates. Rotating the threaded rod drives the clamping plate to move and clamp and fix the surface of the nozzle. However, the overall shapes of nozzles with special-shaped structures are different, and the nozzle with a special-shaped structure cannot be stably clamped and fixed only by the clamping plate. To solve the above problems, some processing toolings for nozzles with special-shaped structures directly fix the nozzle with a special-shaped structure on the processing table by using multiple groups of fixing screws, and then remove the fixing screws after the processing of the nozzle with a special-shaped structure is completed, so as to perform a stable clamping and fixing operation on the nozzle with a special-shaped structure. However, this method of fixing the nozzle with a special-shaped structure by fixing screws is not only inconvenient for disassembling and assembling the nozzle with a special-shaped structure, but also the threaded connection method will become loose under the vibration generated during processing, and the stability of the nozzle with a special-shaped structure during processing cannot be guaranteed. Therefore, a processing tooling for nozzles with special-shaped structures is proposed. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a processing tooling for nozzles with special-shaped structures to solve the technical problems of inconvenient disassembly and assembly of the nozzle with a special-shaped structure and inability to ensure stability during processing.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A processing tooling for nozzles with special-shaped structures, comprising:

[0007] A fixed seat, and side clamping plates arranged on both sides of the top and bottom of the fixed seat, and guide posts are evenly inserted on the surfaces of the side clamping plates;

[0008] A return spring is arranged on the surface of the guide post, and a positioning plate is added to the outer end of the guide post and is attached to the outer side of the side clamping plate. A fixed head is installed at the inner end of the guide post, and both ends of the return spring are respectively attached between the surfaces of the side clamping plate and the fixed head;

[0009] An outer connecting plate is arranged on the outer side of the side clamping plate, and hydraulic rods are installed at the centers of both sides of the top of the fixed seat. The telescopic ends of the hydraulic rods are connected to the outer connecting plate. After the special-shaped structure nozzle is added to the center of the inner cavity of the fixed seat, the hydraulic rod drives the side clamping plate to move through the outer connecting plate. After the fixed head is attached to the surface of the special-shaped structure nozzle, the fixed head drives the guide post to move along the side clamping plate and squeezes the return spring. On the one hand, the special-shaped structure nozzle is fixed on the fixed seat by driving the side clamping plate through the hydraulic rod, so that the disassembly and assembly operations of the special-shaped structure nozzle can be facilitated; on the other hand, through the guide post and the return spring, the surface between the fixed head and the special-shaped structure nozzle can be closely attached, so as to ensure the stability during the processing of the special-shaped structure nozzle.

[0010] Preferably, side outer frames are installed at the center positions of the front and back of the fixed seat, and fixed insertion rods are inserted and connected at the center of the front of the side outer frames. The fixed insertion rods can be inserted and pulled out on the side outer frames.

[0011] Preferably, connecting columns are vertically added to the inner cavity of the side outer frame, and fixing holes are evenly opened on the front of the connecting columns and correspond to the fixed insertion rods. The fixed seat can be arranged at the top and bottom of the connecting column through the side outer frame, and the fixed insertion rods can be inserted into the internal fixing holes for connection, so that the distance between two groups of fixed seats can be adjusted, and it can be applicable to special-shaped structure nozzles of different lengths within a certain range for use.

[0012] Preferably, side extension seats are horizontally installed at the center positions of both sides of the fixed seat, and the center position of the top of the side extension seat is connected to the bottom of the hydraulic rod. The hydraulic rod drives the connecting structure to perform a translation operation at the top of the side extension seat.

[0013] Preferably, a right connecting cylinder is installed at the center position of the outer side of the outer connecting plate, and a limiting groove is opened on the outer side of the center position of the top of the right connecting cylinder. The outer connecting plate can be connected to the corresponding structure through the limiting groove of the right connecting cylinder.

[0014] Preferably, a left connecting cylinder is additionally provided on the outer side of the right connecting cylinder, and an extrusion spring is installed in the inner cavity of the left connecting cylinder. A limiting post is additionally provided on the inner side of the top of the left connecting cylinder, corresponding to a limiting groove, and the left connecting cylinder is connected to the telescopic end of a hydraulic rod. After inserting the right connecting cylinder onto the left connecting cylinder, the limiting post enters the inside of the limiting groove, and the right connecting cylinder is rotated. The extrusion spring drives the right connecting cylinder to move outwards, so that the limiting post and the limiting groove are closely attached to each other, so that the hydraulic rod can drive the outer connecting plate to translate through the left connecting cylinder and the right connecting cylinder, and thus the clamping structure can be replaced according to the special-shaped structure nozzle.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] For this special-shaped structure nozzle processing tooling, after the special-shaped structure nozzle is additionally arranged at the center of the inner cavity of the fixed seat, the hydraulic rod drives the side clamping plate to move through the outer connecting plate. After the fixed head is attached to the surface of the special-shaped structure nozzle, the hydraulic rod drives the side clamping plate to fix the special-shaped structure nozzle on the fixed seat, so that the disassembly and assembly operations of the special-shaped structure nozzle can be facilitated. The fixed head drives the guiding column to move along the side clamping plate and squeezes the return spring. Through the guiding column and the return spring, the fixed head and the surface of the special-shaped structure nozzle can be closely attached to each other, thereby ensuring the stability during the processing of the special-shaped structure nozzle.
