[0002] Nozzles are widely used in the field of military aircraft. They are a device that accelerates the airflow by changing the geometric shape of the inner wall of the pipe. In jet engines, high-pressure gas (or air) is converted into kinetic energy, which accelerates the airflow in the nozzle and ejects it outward at high speed to generate a reaction thrust component, also known as an exhaust nozzle.

[0003] There are many types of nozzles. In the field of military aircraft design, nozzles are selected according to aircraft performance and engine working characteristics. The processing accuracy of the nozzle plays a decisive role in the success of the aircraft thrust vector test. In the existing processing process, the existing clamping method has low efficiency in nozzle processing and lacks the function of easy installation and disassembly, resulting in a low pass rate for nozzle processing, which in turn leads to increased nozzle processing costs and a longer processing cycle.

[0004] To this end, the existing clamping method for processing nozzles has low efficiency and lacks the function of easy installation and disassembly, resulting in a low pass rate for processing nozzles, which in turn leads to increased nozzle processing costs and a long processing cycle. A special tooling for nozzle processing that solves the above problems is needed. Utility Model Content

[0029] Example:

[0030] In conjunction with the instruction manual Figure 1-Figure 5 A special tool for nozzle processing shown in the figure comprises a tooling table 1 and a nozzle assembly 5, wherein the tooling table 1 is fixed on a numerical control device by a vise, and the nozzle assembly 5 comprises a first tube body 51 and a second tube body 52 connected to each other, and a positioning component 2 and a plurality of fixing seats 4 for limiting the nozzle assembly 5 are arranged on the top surface of the tooling table 1;

[0031] The positioning component 2 includes two first positioning seats 21 and two second positioning seats 22. The first positioning seats 21 and the second positioning seats 22 are both provided with pipe grooves. The first tube body 51 abuts against the inside of the pipe groove opened in the first positioning seat 21. The tube wall at the connection between the second tube body 52 and the first tube body 51 abuts against the inside of the pipe groove opened in the second positioning seat 22. A plurality of clamping components 3 are also provided on the top surface of the workbench 1 for fixing the nozzle assembly 5.

[0032] It is worth noting that mechanical processing requires machining equipment, but only equipment and raw materials cannot process mechanical parts. Necessary equipment is also needed, including tools, fixtures, measuring tools, molds, etc. There are general tooling and special tooling. Some special equipment has fewer tooling, and general equipment requires more tooling. The tooling in this application is a special tooling, which requires special design and manufacturing. The special tooling in this application plays an important role in the quality and production efficiency of the nozzle as a whole 5, which can improve work efficiency, shorten processing cycle, improve qualification rate, and avoid the use of conventional clamping methods, which increases the cost of processing nozzles.

[0033] Brief description of working principle:

[0034] The operator first fixes the tooling table 1 on the CNC equipment through a vise, and then uses the pipe grooves provided on the two first positioning seats 21 and the two second positioning seats 22 in the positioning component 2 as positioning references to put the nozzle assembly 5 into the corresponding pipe grooves, so that the pipe wall of the nozzle assembly 5 fits with the pipe groove, and then locks and fixes the nozzle assembly 5 through the cooperation of the bolts and the clamping component 3, so that the pipe wall of the second tube body 52 away from the first tube body 51 is completely fitted with the slot provided on the fixing seat 4, so that the nozzle assembly 5 is stably fixed on the upper end surface of the tooling table 1, and then the nozzle assembly 5 is processed, thereby improving work efficiency, shortening processing cycle, and improving qualification rate, avoiding the use of conventional clamping methods, which increases the cost of processing the nozzle.

[0035] Combined with the accompanying drawings Figure 1-Figure 5 The first positioning seat 21 and the second positioning seat 22 are arranged perpendicular to each other, and the distance between the two first positioning seats 21 is smaller than the length of the first tube body 51, and the distance between the two second positioning seats 22 is also smaller than the length of the second tube body 52.

[0036] It can be understood that in actual processing, the processing accuracy of the nozzle assembly 5 plays a decisive role in the success of the aircraft thrust vector test, and special tooling needs to be specially designed and manufactured, so the setting direction of the first locating seat 21 and the second locating seat 22 corresponds to the connection position direction of the first tube body 51 and the second tube body 52 in the nozzle assembly 5, so as to improve the compatibility of the special tooling and the workpiece being processed, and assist the smooth progress of the processing work.

[0037] Combined with the accompanying drawings Figure 1-Figure 5 The head and tail ends of the first tube body 51 abut against the inside of the tube groove opened in the first positioning seat 21, and the tube wall at the connection between the second tube body 52 and the first tube body 51 abuts against the inside of the tube groove opened in the second positioning seat 22 on either side. There are two fixing seats 4 in total, and each fixing seat 4 is arranged on the same side as the second positioning seat 22. The center of the slot opened on the fixing seat 4 is horizontal to the center of the slot opened on the second positioning seat 22, and the diameter of the slot opened on the fixing seat 4 corresponds to the diameter of the second tube body 52.

[0038] It can be further understood that in the present application, the nozzle assembly 5 includes a first tube body 51 and a second tube body 52, wherein the second tube body 52 is installed away from the tube wall of the first tube body 51 and is in contact with the fixing seat 4. During processing, the fixing seat 4 can support the nozzle assembly 5 and increase the strength of the nozzle, thereby ensuring the stability of the nozzle assembly 5 during processing, further improving the processing efficiency, and reducing the processing cycle.

[0039] It is further worth explaining that the clamping component 3 includes a clamping plate 31 and a cushion block 33. The clamping plate 31 is detachably connected to the top surface of the cushion block 33. A locking groove 32 is provided on the clamping plate 31. A locking hole 34 is provided on the workbench 1 corresponding to the locking groove 32. The bottom surfaces of the plurality of clamping plates 31 are respectively in contact with the head and tail parts of the first tube body 51 and the tube wall of the second tube body 52 away from the first tube body 51, and are screwed and fixed to the locking hole 34 by bolts passing through the locking groove 32.

[0040] It can be understood that the operator only needs to place the nozzle assembly 5 on the workbench 1 and clamp it according to the operating steps. The positioning component 2 and the fixing seat 4 provided on the workbench 1 can be used to preliminarily fix the nozzle assembly 5. Finally, the nozzle assembly 5 is pressed and fixed again by the clamping component 3, so that the nozzle assembly 5 is stably fixed on the upper end surface of the workbench 1, thereby ensuring the stability of the nozzle assembly 5.

[0041] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
