Description

Technical Field

[0001] This utility model relates to the field of turbojet engine technology, and in particular to a test bench for turbojet engines. Background Technology

[0002] A turbojet engine is a jet engine that operates on the principle of a gas turbine and is a core type of aviation power plant. A test bench is a specialized equipment platform used for turbojet engine performance testing, reliability verification, and fault diagnosis. By simulating the actual working environment of the engine, it enables the measurement and control of various engine parameters.

[0003] Existing turbojet engine test benches typically require the turbojet engine to be secured during use to ensure test stability. However, current securing methods mostly rely on threaded rods, which necessitate frequent tightening during positioning, thus affecting test efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the operation process of the positioning method in the prior art is relatively cumbersome, which will result in poor testing efficiency. To this end, we propose a test bench for turbojet engines.

[0005] To achieve the above objectives, this application adopts the following technical solution: A test bench for a turbojet engine, comprising a bench body: a placement plate is installed at the top of the bench body, four adjustment slots are provided at the top of the placement plate, two fixed rods are fixedly connected inside the adjustment slots, adjustment blocks are slidably connected inside the adjustment slots and to the surfaces of the fixed rods, an arc-shaped clamping plate is fixedly connected at the top of the adjustment blocks, four sets of extension plates are fixedly connected at the top of the placement plate, multiple limiting slots are provided on the surfaces of the extension plates, a toggle slot is provided at the top of the adjustment blocks, two toggle plates are slidably connected inside the toggle slot, a snap-fit ​​post is installed at the top of the toggle plate, a snap-fit ​​plate is snapped onto the surface of the snap-fit ​​post, traction slots are provided at the front and rear ends of the toggle slot, traction blocks are slidably connected inside the traction slot, one end of the traction block near the toggle plate is fixedly connected to the toggle plate, fixed pins that are inserted into the limiting slots are fixedly connected to the opposite sides of the toggle plate, and through slots that are slidably connected to the fixed pins are provided on both sides of the toggle slot.

[0006] Preferably, a guide groove is provided at the bottom of the actuating groove, and a guide block is installed at the bottom of the actuating plate, with the inside of the guide groove and the guide block being slidably connected.

[0007] Preferably, a spring is fitted on the surface of the fixing pin, and the two sides of the spring are fixedly connected to the inside of the actuating groove and the actuating plate, respectively.

[0008] Preferably, the surface of the snap-fit ​​post is fitted with a rubber contact sleeve.

[0009] Preferably, a stop groove is provided on both sides of the inside of the adjusting groove, and a stop block is fixedly connected to both sides of the adjusting block, and the inside of the stop groove is slidably connected to the stop block.

[0010] Preferably, an energy storage spring is sleeved on the surface of the fixing rod, and the front end and rear end of the energy storage spring are fixedly connected to the inside of the adjusting groove and the adjusting block, respectively.

[0011] Preferably, the inner diameter of the limiting groove is designed to match the size of the fixing pin.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, when the operator needs to test the turbojet engine, the locking plate is removed from the locking post, releasing the locking plate. The locking plate is then moved to pull the fixing pin out of the limiting groove, releasing the adjusting block from the arc-shaped clamping plate. The arc-shaped clamping plate is then moved to a position close to the turbojet engine. The locking plate is then moved again to re-insert the fixing pin into the limiting groove, locking the locking plate back into the locking post. This allows the arc-shaped clamping plate and the turbojet engine to be fixed synchronously, achieving quick and convenient positioning during turbojet engine testing. By enabling convenient positioning of the turbojet engine, when the operator needs to test it, simple removal, movement, and adjustment are sufficient to achieve convenient positioning, effectively reducing the complexity of positioning operations during testing and significantly improving testing efficiency.

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0022] Reference Figures 1-5As shown, this utility model provides a technical solution: a test bench for a turbojet engine, comprising a bench body 1; a placement plate 2 is mounted on the top of the bench body 1, and four adjustment slots 3 are formed on the top of the placement plate 2; two fixing rods 4 are fixedly connected inside the adjustment slots 3; adjustment blocks 5 are slidably connected to both the inside of the adjustment slots 3 and the surface of the fixing rods 4; an arc-shaped clamping plate 6 is fixedly connected to the top of the adjustment block 5; and four sets of extension plates 7 are fixedly connected to the top of the placement plate 2, with the surface of the extension plates 7 having... Multiple limiting grooves 8 are provided. The top of the adjusting block 5 is provided with a toggle groove 9. Two toggle plates 10 are slidably connected inside the toggle groove 9. A locking post 11 is installed on the top of the toggle plate 10. A locking plate 12 is locked onto the surface of the locking post 11. Traction grooves 13 are provided at both the front and rear ends inside the toggle groove 9. Traction blocks 14 are slidably connected inside the traction grooves 13. The end of the traction block 14 near the toggle plate 10 is fixedly connected to the toggle plate 10. Both sides of the toggle plate 10 are fixedly connected to insert into the limiting grooves 8. The fixed pin 15 and the actuating groove 9 are both provided with through grooves 16 that are slidably connected to the fixed pin 15. When the operator needs to test the turbojet engine, the locking plate 12 is removed from the locking post 11 to release the locking plate 10. Then, the actuating plate 10 is moved to pull the fixed pin 15 out of the limiting groove 8, so that the adjusting block 5 is released from the arc-shaped clamping plate 6. Then, the arc-shaped clamping plate 6 is moved to a position close to the turbojet engine. Then, the actuating plate 10 is moved to insert the fixed pin 15 back into the limiting groove 8, and the locking plate 12 is locked with the locking post 11. The arc-shaped clamping plate 6 is fixed synchronously with the turbojet engine, thereby achieving quick and convenient positioning during turbojet engine testing. By setting up convenient positioning of the turbojet engine, when the operator needs to test it, only simple removal, movement and adjustment are required to achieve convenient positioning of the turbojet engine, thereby effectively reducing the cumbersome positioning operation during the testing process and significantly improving testing efficiency.

[0023] Reference Figure 5 As shown in this embodiment: a guide groove 17 is provided at the bottom of the inside of the actuating groove 9, and a guide block 18 is installed at the bottom of the actuating plate 10. The inside of the guide groove 17 is slidably connected with the guide block 18. Through the setting of the guide groove 17 and the guide block 18, the actuating plate 10 can form a stable guiding effect during the movement inside the actuating groove 9, so that the fixing pin 15 will not be deviated during the insertion into the limiting groove 8, thereby effectively improving the stability of the arc-shaped clamping plate 6 during the fixing process.

[0024] Reference Figure 5As shown in this embodiment: a spring spring 19 is sleeved on the surface of the fixing pin 15. The two sides of the spring spring 19 are fixedly connected to the inside of the actuating groove 9 and the actuating plate 10, respectively. With the setting of the spring spring 19, when the operator needs to adjust the position of the arc-shaped clamping plate 6, the actuating plate 10 is released. At this time, the elastic force stored in the spring spring 19 is released, which drives the fixing pin 15 to be pulled out from the inside of the limiting groove 8, thereby achieving quick release of the limiting when adjusting the position of the arc-shaped clamping plate 6.

[0025] Reference Figure 4 As shown in this embodiment: a rubber contact sleeve 20 is installed on the surface of the snap-fit ​​post 11. By setting the rubber contact sleeve 20, the snap-fit ​​plate 12 and the snap-fit ​​post 11 can have greater friction when snapping, so that the actuating plate 10 will not shake or fall off during the fixing process, effectively improving the fixing effect of the arc-shaped clamping plate 6.

[0026] Reference Figure 3 and Figure 4 As shown in this embodiment: both sides of the adjustment groove 3 are provided with stop grooves 21, and both sides of the adjustment block 5 are fixedly connected with stop blocks 22. The inside of the stop groove 21 is slidably connected to the stop block 22. Through the setting of the stop groove 21 and the stop block 22, the adjustment block 5 can form a stable limiting effect when sliding inside the adjustment groove 3, thereby making the adjustment process of the arc-shaped clamping plate 6 more stable and less prone to displacement, effectively improving the stability of the turbojet engine positioning process.

[0027] Reference Figure 3 As shown in this embodiment: an energy storage spring 23 is sleeved on the surface of the fixing rod 4. The front end and rear end of the energy storage spring 23 are fixedly connected to the inside of the adjusting groove 3 and the adjusting block 5, respectively. With the setting of the energy storage spring 23, when the staff needs to remove the turbojet engine, the adjusting block 5 is released from the fixation. At this time, the elastic force stored in the energy storage spring 23 drives the adjusting block 5 and the arc-shaped clamping plate 6 to move away from the turbojet engine, thereby achieving convenient removal after the turbojet engine test is completed.

[0028] Reference Figure 3 and Figure 5 As shown in this embodiment, the inner diameter of the limiting groove 8 is designed to match the size of the fixing pin 15. By matching the size of the limiting groove 8 with that of the adjusting block 5, the arc-shaped clamping plate 6 can be more stable during the fixing process and is less prone to shaking, thereby making the testing process of the turbojet engine more stable and efficient.

[0029] Working principle: When the operator needs to test the turbojet engine, the locking plate 12 is removed from the locking post 11, releasing the locking plate 10. Then, the locking plate 10 is moved to pull the fixing pin 15 out of the limiting groove 8, releasing the adjusting block 5 from the arc-shaped clamping plate 6. The arc-shaped clamping plate 6 is then moved to a position close to the turbojet engine. The locking plate 10 is then moved again to re-insert the fixing pin 15 into the limiting groove 8, locking the locking plate 12 back into the locking post 11. This allows the arc-shaped clamping plate 6 to be simultaneously fixed to the turbojet engine, achieving quick and convenient positioning during turbojet engine testing. This allows the turbojet engine to be tested... The design allows for convenient positioning of the turbojet engine. When workers need to inspect it, they only need to remove, move, and adjust it to achieve convenient positioning, effectively reducing the complexity of positioning operations during testing and significantly improving testing efficiency. The guide groove 17 and guide block 18 ensure stable guidance for the actuating plate 10 as it moves within the actuating groove 9, preventing the fixing pin 15 from shifting when inserted into the limiting groove 8. This effectively improves the stability of the arc-shaped clamping plate 6 during fixation. The spring spring 19 further enhances stability when workers need to move the arc-shaped clamping plate 6. When adjusting the position of the holding plate 6, the toggle plate 10 is released. This releases the stored elastic force in the spring spring 19, causing the fixing pin 15 to be pulled out of the limiting groove 8. This achieves rapid release of the limiting position during the adjustment of the arc-shaped clamping plate 6. The rubber contact sleeve 20 provides greater friction between the locking plate 12 and the locking post 11 during engagement, preventing the toggle plate 10 from shaking or falling off during fixing and effectively improving the fixing effect of the arc-shaped clamping plate 6. The stop groove 21 and stop block 22 ensure stable limiting when the adjusting block 5 slides within the adjusting groove 3. The adjustment process of the arc-shaped clamping plate 6 is made more stable and less prone to displacement, effectively improving the stability of the turbojet engine positioning process. With the setting of the energy storage spring 23, when the operator needs to remove the turbojet engine, the adjusting block 5 is released from the fixation. At this time, the elastic force stored in the energy storage spring 23 drives the adjusting block 5 and the arc-shaped clamping plate 6 to move away from the turbojet engine, thereby achieving convenient removal after the turbojet engine test is completed. With the setting of the limit groove 8 matching the size of the adjusting block 5, the arc-shaped clamping plate 6 can be made more stable during the fixing process and less prone to shaking, thus making the turbojet engine testing process more stable and efficient.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
