Description

Technical Field

[0001] This utility model belongs to the field of engine technology, specifically relating to an effective engine intake thrust detection device. Background Technology

[0002] An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, and electric motors. For example, internal combustion engines typically convert chemical energy into mechanical energy. The term "engine" can refer to both the power-generating device and the entire machine including the power unit, such as a gasoline engine or an aircraft engine.

[0003] During engine production, various parameters need to be tested, one of which is the intake thrust test. The intake thrust test measures the driving force generated during engine intake. Existing intake thrust testing equipment lacks a stable fixing mechanism for the engine during testing, which can easily cause shaking during engine intake and start-up, thus affecting the smooth progress of normal testing operations. Therefore, we propose an effective engine intake thrust testing device. Utility Model Content

[0004] The purpose of this invention is to provide an effective engine intake thrust testing device to solve the problem mentioned in the background art that the existing intake thrust testing devices lack a stable fixing mechanism for the engine during the testing process, and the engine is prone to shaking during intake and start-up, which affects the smooth progress of normal testing operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-performance engine intake thrust testing device, comprising a test bench, a placement frame fixedly mounted on the side of the test bench, a cylinder fixedly mounted on the inner wall of the placement frame, a mounting plate fixedly mounted on the piston rod end of the cylinder, four hinged arms hingedly mounted on the mounting plate, a sliding seat hingedly mounted on the end of each hinged arm away from the mounting plate, the sliding seat slidably mounted inside a slide rail opened on the upper surface of the placement frame, a locking plate fixedly mounted on the upper surface of the sliding seat, and a locking plate at the right side position. A strap is fixedly installed on the surface of the plate. A card holder is fixedly installed on the surface of the carding plate at the left position. The strap and the card holder are used together. A test cylinder, a timer and a scale plate are fixedly installed on the surface of the test stage. A telescopic hose is connected to one end of the test cylinder. A sliding disk is slidably installed on the inner wall of the test cylinder. The sliding disk is sealed and fitted to the inner wall of the test cylinder. A sliding column is fixedly installed on the back of the sliding disk. The end of the sliding column away from the sliding disk slides through and extends out of the test cylinder and is fixedly installed with a speed tester and a pointer. The pointer is used together with the scale plate.

[0006] The above scheme utilizes a cylinder in conjunction with a mounting plate, articulated arm, sliding seat, and locking plate. The cylinder's contraction drives the mounting plate downwards, and the articulation of the articulated arm drives the sliding seat to move the locking plate inwards, achieving four-way (front, rear, left, and right) fixing of the engine. A strap around the engine, combined with the locking seat and locking rod, secures the engine longitudinally, preventing shaking during testing and improving operational stability. A flexible hose is used in conjunction with the engine exhaust pipe, sliding plate, and sliding column. Utilizing the principle of interaction of forces, the exhaust force drives the sliding plate within the test cylinder, which in turn drives the sliding column to move the pointer. The pointer indicates the sliding distance on the scale. A timer and speed tester are used to measure the speed. The acceleration of the sliding plate can be calculated using physics formulas, and the exhaust thrust can then be calculated, which is the same as the intake thrust. This results in highly accurate test results.

[0007] In the above scheme, it should be noted that the cylinder, speed tester and timer are all electrically connected to an external power supply.

[0008] In one preferred embodiment, a plurality of guide rods are fixedly installed on the inner wall of the placement rack, and the mounting plate is slidably installed on the outer surface of the plurality of guide rods.

[0009] Using the above scheme, when the cylinder drives the mounting plate to move up and down, the mounting plate will slide on the surface of the guide rod. The design of the guide rod ensures that the mounting plate can move up and down stably.

[0010] In a preferred embodiment, a guide rod two is fixedly installed on the inner wall of the slide rail on the placement rack, and the sliding seat is slidably installed on the outer surface of the guide rod two.

[0011] By adopting the above solution and setting the second guide rod, it can be ensured that the sliding seat can slide stably in the slide rail, thereby ensuring the stable movement of the positioning plate and preventing shaking.

[0012] In a preferred embodiment, the side of the card slot plate is covered with an anti-slip pad.

[0013] By adopting the above solution, the anti-slip pad can provide a fixed and anti-slip effect when the mounting plate is clamped to the engine, improving the stability of the fixing effect. It can also avoid direct contact between the mounting plate and the engine surface, providing an isolation and protection effect and preventing squeezing damage.

[0014] In a preferred embodiment, a locking rod is slidably mounted on the card holder, an operating disc is fixedly mounted on the top end of the locking rod, a spring is fixedly mounted between the operating disc and the card holder, and a plurality of locking holes are provided on the strap, with the other end of the locking rod cooperating with the locking holes.

[0015] Using the above solution, pulling the operating disc drives the locking rod to disengage from the card seat. At this time, the spring deforms and the strap can be inserted into the card seat. The spring force drives the locking rod to engage with the lock hole, realizing the locking after the strap is wrapped around the engine. The structure is simple and the operation is convenient.

[0016] In a preferred embodiment, the telescopic hose is threaded with a number of bolts.

[0017] Using the above method, the flexible hose can be connected to the engine's exhaust pipe by using bolts.

[0018] In a preferred embodiment, a plurality of sliding rods are fixedly installed on the inner wall of the test cylinder, and the sliding disk is slidably installed on the outer surface of the plurality of sliding rods.

[0019] By adopting the above scheme, the sliding rod can be used to support and guide the sliding process of the sliding disk, improve the stability of the movement, and avoid wobbling.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This effective engine intake thrust testing device uses a cylinder in conjunction with a mounting plate, articulated arm, sliding seat, and locking plate. The cylinder retraction drives the mounting plate downward, and the articulation of the articulated arm drives the sliding seat to move the locking plate inward, achieving four-way fixed locking of the engine. Furthermore, the straps are wrapped around the engine and locked in conjunction with the locking seat and locking rod to achieve longitudinal circumferential binding of the engine, thereby preventing shaking during the test and improving the stability of the test operation.

[0022] This effective engine intake thrust testing device uses a telescopic hose in conjunction with the engine exhaust pipe, a sliding disc, and a sliding column. Utilizing the principle of interaction between forces, the exhaust force during exhaust causes the sliding disc to slide within the test cylinder, which in turn drives the sliding column to move the pointer. The value indicated by the pointer on the scale represents the sliding distance of the disc. Combined with a timer and a speed tester, the acceleration of the sliding disc can be calculated using physics formulas, and then the exhaust thrust can be determined. This exhaust thrust is the intake thrust, resulting in highly accurate test results. Attached Figure Description

[0029] Please see Figure 1-5 This utility model provides an effective engine intake thrust testing device, including a test bench 1. A placement rack 2 is fixedly installed on the side of the test bench 1. A cylinder 3 is fixedly installed on the inner wall of the placement rack 2. A mounting plate 4 is fixedly installed on the piston rod end of the cylinder 3. Four hinged arms 5 are hingedly installed on the mounting plate 4. A sliding seat 6 is hingedly installed at the end of the hinged arm 5 away from the mounting plate 4. The sliding seat 6 is slidably installed inside a slide rail opened on the upper surface of the placement rack 2. A locking plate 7 is fixedly installed on the upper surface of the sliding seat 6. A strap 8 is fixedly installed on the surface of the locking plate 7 at the right position. A strap 8 is fixedly installed on the surface of the locking plate 7 at the left position. A mounting bracket 9 is fixedly installed on the surface of the mounting plate 7. The strap 8 is used in conjunction with the mounting bracket 9. A test cylinder 10, a timer 11, and a scale plate 12 are fixedly installed on the surface of the test stage 1. A telescopic hose 13 is connected to one end of the test cylinder 10. A sliding disk 14 is slidably installed on the inner wall of the test cylinder 10. The sliding disk 14 is sealed and fitted to the inner wall of the test cylinder 10. A sliding column 15 is fixedly installed on the back of the sliding disk 14. The end of the sliding column 15 away from the sliding disk 14 slides through and extends out of the test cylinder 10 and is fixedly installed with a speed tester 16 and a pointer 17. The pointer 17 is used in conjunction with the scale plate 12.

[0030] By using cylinder 3 in conjunction with mounting plate 4, hinge arm 5, sliding seat 6, and locking plate 7, the retraction of cylinder 3 drives mounting plate 4 downward, and the hinge arm 5, in turn, drives sliding seat 6 to move locking plate 7 inward, thus achieving four-way fixed locking of the engine. Furthermore, the strap 8, after passing around the engine, locks in place with locking seat 9 and locking rod 21, achieving longitudinal circumferential binding of the engine. This prevents shaking during testing and improves the stability of the testing operation. A telescopic hose 13 is also installed to connect to the engine exhaust... The tube works in conjunction with the sliding disk 14 and the sliding column 15. Utilizing the principle that forces interact, the exhaust force drives the sliding disk 14 to slide within the test cylinder 10 during exhaust, which in turn drives the sliding column 15 to move the pointer 17. The value indicated by the pointer 17 on the scale plate 12 is the sliding distance of the sliding disk 14. With the timer 11 for timing and the speed tester 16 for speed measurement, the acceleration of the sliding disk 14 can be calculated first using physical formulas, and then the exhaust thrust can be calculated. The exhaust thrust is the same as the intake thrust, resulting in highly accurate test results.

[0031] Several guide rods 18 are fixedly installed on the inner wall of the placement rack 2. The mounting plate 4 is slidably installed on the outer surface of the guide rods 18. When the cylinder 3 drives the mounting plate 4 to move up and down, the mounting plate 4 will slide on the surface of the guide rods 18. The setting of the guide rods 18 can ensure that the mounting plate 4 can move up and down stably.

[0032] A guide rod 2 19 is fixedly installed on the inner wall of the slide rail on the placement frame 2. The sliding seat 6 is slidably installed on the outer surface of the guide rod 2 19. By setting the guide rod 2 19, it can be ensured that the sliding seat 6 can slide stably in the slide rail, thereby ensuring the stable movement of the positioning plate 7 and preventing shaking.

[0033] The side of the mounting plate 7 is covered with an anti-slip pad 20. The anti-slip pad 20 can provide a fixed and anti-slip effect when the mounting plate 7 is clamped to the engine, improving the stability of the fixing effect. It can also prevent direct contact between the mounting plate 7 and the engine surface, providing an isolation and protection effect to avoid squeezing damage.

[0034] A locking rod 21 is slidably mounted on the mounting base 9. An operating disc 22 is fixedly mounted on the top of the locking rod 21. A spring 23 is fixedly mounted between the operating disc 22 and the mounting base 9. Several locking holes are opened on the strap 8. The other end of the locking rod 21 is used in conjunction with the locking holes. Pulling the operating disc 22 drives the locking rod 21 to disengage from the mounting base 9. At this time, the spring 23 deforms and the strap 8 can be inserted into the mounting base 9. The elastic force of the spring 23 drives the locking rod 21 to engage with the locking holes, thereby achieving the locking of the strap 8 after it bypasses the engine and is secured. The structure is simple and the operation is convenient.

[0035] Several bolts 24 are threaded onto the flexible hose 13. By using the bolts 24, the flexible hose 13 can be connected to the exhaust pipe of the engine.

[0036] Several sliding rods 25 are fixedly installed on the inner wall of the test cylinder 10. The sliding disk 14 is slidably installed on the outer surface of the sliding rods 25. The sliding rods 25 can be used to support and guide the sliding process of the sliding disk 14, improve the stability of the movement, and avoid shaking.

[0037] In use, place the engine to be tested on the surface of the mounting bracket 2, start cylinder 3, and use the retraction of cylinder 3 to drive the mounting plate 4 downward, which, together with the hinge arm 5, drives the sliding seat 6 to move the locking plate 7 inward, thus fixing and locking the engine in four directions: front, back, left, and right. Then stop cylinder 3, pull the operating plate 22 to drive the locking rod 21 to move and disengage from the mounting bracket 9. At this time, the spring 23 deforms, and then the strap 8 is wrapped around the engine and passed through the mounting bracket 9 to achieve longitudinal wrapping binding of the engine. Then release the operating plate 22, and use the elastic force of the spring 23 to drive the locking rod 21 to insert into the locking hole, thereby locking the position of the strap 8 and preventing shaking during the test. To improve the stability of the test operation, the telescopic hose 13 is then assembled and connected to the engine exhaust pipe using bolts 24. Utilizing the principle that forces interact, the engine exhausts while intake air is being intaked. During exhaust, the exhaust force drives the sliding disk 14 to slide within the test cylinder 10, which in turn drives the sliding column 15 to move the pointer 17. The value indicated by the pointer 17 on the scale plate 12 is the sliding distance of the sliding disk 14. With the timer 11 for timing and the speed tester 16 for speed measurement, the acceleration of the sliding disk 14 can be calculated using physical formulas, and then the exhaust thrust can be calculated. The exhaust thrust is the same as the intake thrust, resulting in high accuracy of the test results.
