Technical Field

[0001] This utility model relates to the field of gas turbine blade processing technology, specifically to a micro-nano level coolant sprayer for precision machining of gas turbine blades. Background Technology

[0002] In the precision machining of gas turbine blades, coolant is needed to cool and lubricate the machining area in order to ensure machining accuracy and blade surface quality. Traditional coolant supply methods are mostly pouring, which has problems such as large coolant consumption, uneven cooling, and difficulty in reaching the tiny gaps in precision machining. Moreover, for micro-nano-scale coolants, the pouring supply method cannot achieve uniform and efficient spraying, which affects the machining quality and efficiency of gas turbine blades.

[0003] Existing coolant sprayers cannot control the spray range of coolant during the precision machining of gas turbine blades, resulting in uneven coolant spraying. This leads to insufficient cooling and lubrication in some machining areas, while other areas may suffer from excessive coolant, affecting the machining effect. Therefore, those skilled in the art provide a micro-nano-scale coolant sprayer for the precision machining of gas turbine blades to solve the problems mentioned in the background art. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-5 As shown, this utility model provides a technical solution: a micro-nano-level coolant sprayer for precision machining of gas turbine blades, including a mounting plate 1, a storage tank 2 for storing coolant at the top of the mounting plate 1, and a spraying mechanism 3 for spraying coolant at the bottom of the storage tank 2. The spraying mechanism 3 includes a sprayer body 301 installed at the bottom of the storage tank 2. The sprayer body 301 is located at the bottom of the mounting plate 1. A hose 302 is connected through the output end of the sprayer body 301. A connecting pipe 303 is connected through the output end of the hose 302. A nozzle 304 is connected through the output end of the connecting pipe 303.

[0023] The coolant in the storage tank 2 is drawn by the sprayer body 301 and transmitted to the connecting pipe 303 through the hose 302. Finally, it is sprayed out from the nozzle 304 in the form of micro-nano mist, which can effectively cool and lubricate the blades, thereby improving the processing accuracy and efficiency.

[0024] It should be noted that the model of the sprayer body 301 is YS-PBV-3000. The sprayer body 301 is existing technology and will not be described in detail here.

[0025] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 As shown, a mounting sleeve 4 is fixedly fitted on the bottom surface of the hose 302. The mounting sleeve 4 is located above the connecting pipe 303, and a clamp 401 is hinged to the end of the mounting sleeve 4 away from the hose 302.

[0026] The mounting sleeve 4 and the clamp 401 serve to fix and support the hose 302, ensuring that the hose 302 will not shake freely when transmitting coolant, thus guaranteeing the stability of the spray.

[0027] As one implementation method in this embodiment, please refer to Figure 1 , Figure 3 and Figure 4 As shown, the bottom end of the spray mechanism 3 is provided with a protective cover mechanism 5 for controlling the spray range of coolant. The protective cover mechanism 5 includes two sets of covers 501 hinged to the surface of the connecting pipe 303. The two sets of covers 501 are located outside the nozzle 304. A telescopic piece 502 is fixedly connected between the two sets of covers 501. A sleeve rod 503 is hinged to the top of each set of covers 501. A telescopic rod 504 is slidably fitted on the surface of each set of sleeve rods 503. Locking holes 505 are equidistantly opened on the surface of one set of sleeve rods 503. The ends of the two sets of telescopic rods 504 away from the two sets of sleeve rods 503 are hinged to both sides of the surface of the hose 302 through a hinge.

[0028] The two sets of covers 501 are connected by two sets of telescopic plates 502. The opening and closing degree of the two sets of covers 501 can be adjusted according to actual needs, thereby controlling the coverage area of ​​the spray. The sleeve rod 503 and telescopic rod 504 at the top of the two sets of covers 501 allow the two sets of covers 501 to be adjusted in the vertical direction to adapt to the needs of different processing angles.

[0029] As one implementation method in this embodiment, please refer to Figure 4 and Figure 5 As shown, the surface of the protective cover mechanism 5 is provided with a locking mechanism 6 for fixing the range of the protective cover mechanism 5. The locking mechanism 6 includes a mounting post 601 installed on the outer wall of one of the sets of telescopic rods 504. A spring 602 is fitted on the surface of the mounting post 601. A sleeve plate 603 is slidably fitted on the surface of the mounting post 601. The sleeve plate 603 is located on one side of the spring 602. A plug rod 604 is fixedly installed at the end of the sleeve plate 603 away from the mounting post 601. The end of the plug rod 604 away from the sleeve plate 603 is inserted into the interior of one of the sets of lock holes 505.

[0030] The engagement of the insert rod 604 with the locking hole 505 allows for the fixation of the telescopic rod 504, thereby stabilizing the opening and closing of the two sets of covers 501 and ensuring precise control of the spray range. The spring 602 provides elastic force to the sleeve plate 603 and the insert rod 604, enabling the insert rod 604 to smoothly insert into or pull out of the locking hole 505. By adjusting the engagement of the insert rod 604 with the locking holes 505 at different positions, the opening and closing angles of the two sets of covers 501 can be flexibly adjusted to meet different processing requirements.

[0031] Working principle: When the gas turbine blades need to be precision machined, the micro-nano-level coolant sprayer starts to work. First, the coolant in the storage tank 2 is drawn by the sprayer body 301 and transferred to the connecting pipe 303 through the hose 302. Finally, it is sprayed out from the nozzle 304 in the form of micro-nano-level mist, which can effectively cool and lubricate the blades, thereby improving the machining accuracy and efficiency. During the spraying process, the mounting sleeve 4 and the clamp 401 at the bottom of the hose 302 play a role in fixing and supporting, ensuring that the hose 302 will not shake randomly when transmitting coolant, thus ensuring the stability of the spray.

[0032] Meanwhile, the protective cover mechanism 5 at the bottom of the spray mechanism 3 can control the spray range of the coolant. The two sets of covers 501 are connected by two sets of telescopic plates 502. The opening and closing degree of the two sets of covers 501 can be adjusted according to actual needs, thereby controlling the coverage area of ​​the spray. The sleeve rod 503 and telescopic rod 504 at the top of the two sets of covers 501 allow the two sets of covers 501 to be adjusted in the vertical direction to adapt to the needs of different processing angles. After the positions of the two sets of covers 501 are adjusted, the telescopic rod 504 is fixed in the required position by inserting the insertion rod 604 into one of the locking holes 505 under the elastic force of the spring 602. This ensures the stability of the protective cover mechanism 5 and realizes precise control of the coolant spray range, providing strong support for the precision machining of gas turbine blades.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
