Description

Technical Field

[0001] The present invention belongs to the technical field of rotational speed testing, and specifically relates to a combined engine rotational speed testing device. Background Art

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. Before leaving the factory, the engine needs to be tested for rotational speed. By testing the performance of the engine at different rotational speeds, it is possible to comprehensively evaluate whether its performance indicators meet the design or improvement requirements, and promptly detect possible faults or potential problems in the engine, avoiding the use of unqualified engines in subsequent operations.

[0003] The patent with the publication number CN218995411U discloses a combined engine rotational speed testing device. In view of the problems of the existing device that need to be adjusted for different engine output shafts and cannot be easily sleeved with the output shaft, the following solution is proposed. It includes a fixing plate, a through pipe, and an extrusion assembly. A through pipe is disposed through the center of the interior of the fixing plate, and an extrusion assembly is installed around the through pipe near the outer wall of the fixing plate. An arc plate is provided on one end side wall of the fixing plate, and the arc plate is connected to the fixing plate through a transmission assembly; the through pipe for sleeving with the engine is provided with a plurality of extrusion blocks around one end near the extrusion assembly, and a circumferential tooth is provided on the outer wall of the through pipe far from the extrusion blocks. This patent has the advantage of being convenient for detecting power output shafts with different diameters and those that are not easily sleeved through the combination of different components.

[0004] However, the above technical solution still has the following deficiencies in actual application: By inserting the engine output shaft into the through pipe by the staff, driving the engine to drive the through pipe to rotate, and using a detector to detect the rotating through pipe to achieve the rotational speed test. However, in some cases, the rotational speed tests of multiple engines are carried out in sequence. Therefore, it is necessary for the staff to frequently remove the engines that have completed the test. After being removed, the engines may be concentrated and stacked in a messy state at the same place, which may cause the engines with qualified and unqualified test results to be easily mixed together. As a result, the engines with unqualified test results may be put into subsequent use. When the staff manually separates the engines with qualified and unqualified test results, it is rather laborious, which not only increases the labor intensity of the workers, but also is prone to placing the engines with qualified and unqualified test results together due to operation errors. Moreover, for the engines with unqualified rotational speed tests, the workers need to analyze the reasons, and according to the results of the reason analysis, select the engines that can be solved by repair from the unqualified engines. For the engines that cannot be solved by repair, they need to be scrapped according to relevant regulations. If the unqualified engines are placed in a messy state, it will affect the workers' sequential analysis of the reasons for the engines, and it is easy to cause confusion.

[0005] Therefore, the present invention provides a combined engine rotational speed test device. Summary of the Invention

[0016] Preferably, a collection box is arranged on one side of the upper end surface of the base. The collection box is located at the end of the conveyor belt.

[0017] The beneficial effects of the present invention are as follows: 1. In a combined engine speed testing device according to the present invention, during the testing process, since the engine is fixed by two positioning blocks, the stability of the engine during the testing process is ensured, and the overall deviation of the engine caused by the rotation of the output shaft of the engine will not occur, thus preventing the situation that affects the smooth progress of the testing work.

[0018] 2. In a combined engine speed testing device according to the present invention, by using an arranged placement mechanism, according to the test results of the engine speed, for the engines with qualified test results, they will move into the collection box for collection, and for the engines with unqualified engine speed test results, they will slide onto the receiving plate. This avoids the situation where engines with qualified and unqualified test results are mixed together, and further avoids the situation that unqualified engines are put into subsequent use. At the same time, it also eliminates the process of workers manually placing the engines separately, reducing the labor intensity of the workers, and also preventing the situation that engines with qualified and unqualified test results are placed together due to operation errors. Moreover, since the unqualified engines slide onto the receiving plate in sequence, multiple engines will be in an arranged state. At this time, the staff can analyze the reasons for the unqualified situation of multiple engines in sequence. The analysis process is relatively orderly and is not prone to confusion. After the analysis is completed, the second baffle can be driven to descend, causing the engines to fall from the end of the receiving plate. At this time, the workers can use a collection container to collect the engines. And when the workers analyze the reasons for the unqualified engines, if they find an engine that can be repaired to solve the problem, the workers can drive the push block to align with the engine that can be repaired to solve the problem, push the engine off the edge of the receiving plate, and collect it with a collection container, so that multiple engines that can be repaired to solve the problem can be separately screened out. This avoids the situation that unqualified engines uniformly fall from the end of the receiving plate into the collection container, which may lead to the mixing of repairable and non-repairable engines and affect the smooth progress of subsequent repair work. And whenever a test-unqualified engine moves onto the receiving plate, the push rod will move and squeeze the anti-touch plate. The anti-touch plate will extend towards the inside of the receiving plate due to the push of the push rod. When the subsequent engines slide onto the receiving plate, the anti-touch plate will block them, preventing the two engines from contacting. By repeating the above operation, multiple engines can be separated by the anti-touch plate. When using the push block to push the engine, the situation that the pushed engine drives the adjacent engine to move due to friction will not occur, ensuring that the push block can only push down one engine at a time. And since each anti-touch plate corresponds to a digital mark, the engine in contact with the anti-touch plate will also correspond to the digital mark. After the workers find an engine that can be repaired to solve the problem, they record the corresponding number. When the reason analysis is completed, the recorded numbers can be uniformly input into the controller, and the controller will drive the push block to push the engine at the corresponding digital position, making the movement trajectory of the push block relatively regular and the adjustment process simple, which is conducive to improving work efficiency.

[0023] Please refer to Figures 1-8, the present invention provides a technical solution: a combined engine speed testing device, including a base 1. One side of the upper end face of the base 1 is fixedly connected with a frame 2. A conveyor belt 3 is arranged on the frame 2.

[0034] Specifically, when the existing engine speed testing device is in use, the operator inserts the engine output shaft into the through pipe, drives the engine to drive the through pipe to rotate, and uses a detector to detect the rotating through pipe to achieve speed testing. However, in some cases, the speed of multiple engines needs to be tested in sequence. Therefore, the operator needs to frequently remove the tested engines. After removal, the engines may be stacked together in a messy state, which may cause the engines with qualified and unqualified test results to be easily mixed together. As a result, an engine with an unqualified test result may be put into subsequent use. When the operator manually separates the engines with qualified and unqualified test results, it is quite laborious, which not only increases the labor intensity of the workers but also easily leads to the situation where the engines with qualified and unqualified test results are placed together due to operation errors. Moreover, for engines with unqualified speed tests, the operator needs to analyze the reasons and select the engines that can be solved by repair from the unqualified engines according to the analysis results. For engines that cannot be solved by repair, they need to be scrapped according to relevant regulations. If the unqualified engines are placed messily, it will affect the operator's sequential analysis of the reasons for the engines and easily lead to confusion; Therefore, to solve the above problems, when this embodiment is in use, after the engine speed test is completed, the two positioning blocks 36 are driven to move away from each other to loosen the engine. According to the test result of the speed, the motor five 33 drives the guide plate 34 to rotate. For the engines with qualified test results, one end of the guide plate 34 will approach the collection box 6, and as the conveyor belt 3 runs, the qualified engines will move into the collection box 6, thus achieving the separate collection of the qualified engines; For the engines with unqualified speed test results, the end of the guide plate 34 will approach the receiving plate 11, and the unqualified engines will slide into the receiving plate 11. By repeating the above operations, the engines with qualified and unqualified speed test results can be placed separately, thus avoiding the situation where an engine with an unqualified test result is put into subsequent use due to the mixed placement of engines with qualified and unqualified test results. At the same time, it also eliminates the process of the operator manually separating the engines, reduces the labor intensity of the workers, and will not lead to the situation where the engines with qualified and unqualified test results are placed together due to operation errors; Moreover, since the unqualified engines slide onto the receiving plate 11 in sequence, multiple engines will be in an arranged state. At this time, the staff can analyze the reasons for the unqualified of multiple engines in sequence. The analysis process is relatively orderly and it is not easy to be confused. After the analysis is completed, the second motor 19 can be used to drive the fourth threaded rod 30 to rotate, causing the second baffle 18 to descend. When the second baffle 18 no longer blocks the engine, the engine will fall from the end of the receiving plate 11. At this time, the worker can use a collection container to collect the engine. However, during the analysis of the unqualified reasons, the worker will screen out the engines that can be repaired to solve the problem. If the unqualified engines fall uniformly from the end of the receiving plate 11 into the collection container, it will cause the repairable engines and the non-repairable engines to be mixed together, thus affecting the subsequent repair work of the engines. Therefore, to avoid this situation, when the worker analyzes the reasons for the unqualified engines, if it is found that the problem of the engine can be solved by repair, then the worker can use the first electric push rod 17 to drive the first baffle 12 to slide downwards, so that the first baffle 12 no longer blocks the engine on the receiving plate 11. Then, use the first motor 8 to drive the first threaded rod 9 to rotate, causing the displacement plate 25 to move until the push block 27 aligns with the engine that can be repaired to solve the problem. Then, use the second electric push rod 23 to drive the push block 27 to move and contact the engine. Then, use the fourth motor 29 to drive the third threaded rod 28 to rotate, causing the push block 27 to slide inside the chute plate 26, and the engine at the corresponding position can be pushed off from the edge of the receiving plate 11 and collected using a collection container. Then, repeat the above operation to separately screen out multiple engines that can be repaired to solve the problem, thus avoiding the situation where the unqualified engines fall uniformly from the end of the receiving plate 11 into the collection container, which in turn causes the repairable engines and the non-repairable engines to be mixed together and affects the smooth progress of the subsequent repair work; Moreover, although the pusher block 27 can be used to separately screen out the engines that can be repaired to solve problems, since the adjacent engines on the receiving plate 11 are in contact with each other, when the pusher block 27 pushes an engine, the pushed engine may drive the adjacent engine to move due to friction, resulting in multiple engines falling off the receiving plate 11 at the same time. Also, whenever a worker discovers an engine that can be repaired to solve problems, if the pusher block 27 is used to push it out each time, the movement trajectory of the pusher block 27 is relatively irregular, and it is necessary to frequently control the pusher block 27 to align with the engines at various positions, and the operation process is relatively cumbersome, affecting work efficiency. Therefore, to solve this problem, whenever a tested unqualified engine moves onto the receiving plate 11, the third motor 20 will drive the second threaded rod 21 to rotate, causing the push rod 16 to slide on the second slide rod 22, so that the push rod 16 can squeeze the anti-touch plate 13. Since one side of the anti-touch plate 13 is an inclined surface, the anti-touch plate 13 will move due to the push of the push rod 16 and extend towards the inside of the receiving plate 11. When the subsequent engines slide onto the receiving plate 11, the anti-touch plate 13 will block them, preventing two engines from coming into contact. By repeating the above operation, multiple engines can be separated by the anti-touch plate 13. When the pusher block 27 is used to push the engines, the situation where the pushed engine drives the adjacent engine to move due to friction will not occur, ensuring that the pusher block 27 can only push down one engine at a time. Also, since each anti-touch plate 13 corresponds to a digital mark 31, the engines in contact with the anti-touch plate 13 will also correspond to the digital mark 31. After the worker discovers an engine that can be repaired to solve problems, record the corresponding number. When the cause analysis is completed, the recorded numbers can be uniformly input into the controller, and the controller will drive the pusher block 27 to push the engine at the corresponding digital position, making the movement trajectory of the pusher block 27 relatively regular and the operation simple.

[0035] Working principle: Place the engine to be tested for rotational speed between two positioning blocks 36 on the conveyor belt 3. Then, use the electric push rods III 35 on both sides to drive the two positioning blocks 36 to move simultaneously and approach the engine. When both positioning blocks 36 come into contact with the engine, the engine can be fixed. At this time, the output shaft of the engine is aligned with the test head 32. Then, use the rotational speed tester 5 to test the rotational speed of the engine in a non-contact manner. This rotational speed tester 5 and the testing process are prior arts and will not be elaborated here. During the testing process, since the two positioning blocks 36 fix the engine, the stability of the engine during the testing process is ensured, and the overall offset of the engine caused by the rotation of the output shaft of the engine will not occur, thus affecting the smooth progress of the testing work. When the rotational speed testing work of the engine is completed, drive the two positioning blocks 36 to move away from each other to release the engine. According to the test result of the rotational speed, use the motor V 33 to drive the guide plate 34 to rotate. For the engine with qualified test results, one end of the guide plate 34 will approach the collection box 6, and as the conveyor belt 3 operates, the qualified engines will move into the collection box 6, thus realizing the separate collection of qualified engines; for the engines with unqualified rotational speed test results, the end of the guide plate 34 will approach the receiving plate 11, and the unqualified engines will slide into the receiving plate 11. Repeat the above operations to separately place the engines with qualified and unqualified rotational speed test results, thus avoiding the situation where the engines with unqualified test results are put into subsequent use due to the mixed placement of engines with qualified and unqualified test results. At the same time, it also eliminates the process of manual separation of engines by workers, reduces the labor intensity of workers, and will not cause the engines with qualified and unqualified test results to be placed together due to operation errors;Moreover, since the unqualified engines slide onto the receiving plate 11 in sequence, multiple engines will be in an arranged state. At this time, the staff can analyze the reasons for the unqualified of multiple engines in sequence. The analysis process is relatively orderly and it is not easy to be confused. After the analysis is completed, the second motor 19 can be used to drive the fourth threaded rod 30 to rotate, so that the second baffle 18 descends. When the second baffle 18 no longer blocks the engine, the engine will fall from the end of the receiving plate 11. At this time, the worker can use the collection container to collect the engine. However, during the analysis of the unqualified reasons, the worker will screen out the engines that can solve the problem through repair. If the unqualified engines fall uniformly from the end of the receiving plate 11 into the collection container, it will cause the repairable engines and the non-repairable engines to be mixed together, thus affecting the subsequent repair work of the engine. Therefore, to avoid this situation, when the worker analyzes the reasons for the unqualified engines, if it is found that the engine can solve the problem through repair, then the worker can use the first electric push rod 17 to drive the first baffle 12 to slide downward, so that the first baffle 12 no longer blocks the engine on the receiving plate 11. Then use the first motor 8 to drive the first threaded rod 9 to rotate, so that the displacement plate 25 moves until the push block 27 is aligned with the engine that can solve the problem through repair. Then use the second electric push rod 23 to drive the push block 27 to move and contact the engine. Then use the fourth motor 29 to drive the third threaded rod 28 to rotate, so that the push block 27 slides inside the chute plate 26, and the engine at the corresponding position can be pushed off from the edge of the receiving plate 11 and collected by the collection container. Then repeat the above operation, and multiple engines that can solve the problem through repair can be separately screened out, thus avoiding the situation that the unqualified engines fall uniformly from the end of the receiving plate 11 into the collection container, which in turn causes the repairable engines and the non-repairable engines to be mixed together and affects the smooth progress of the subsequent repair work;Moreover, although the pusher block 27 can be used to separately screen out the engines whose problems can be solved by repair, since the adjacent engines on the receiving plate 11 are in contact with each other, when the pusher block 27 pushes an engine, the pushed engine may drive the adjacent engine to move due to friction, resulting in multiple engines falling from the receiving plate 11 at the same time. And whenever a worker finds an engine whose problems can be solved by repair, if the pusher block 27 is used to push it out, the movement trajectory of the pusher block 27 is relatively irregular, and it is necessary to frequently control the pusher block 27 to align with the engines at various positions, and the operation process is rather cumbersome, affecting work efficiency. Therefore, to solve this problem, whenever a tested unqualified engine moves onto the receiving plate 11, the third motor 20 will drive the second threaded rod 21 to rotate, causing the push rod 16 to slide on the second slide rod 22, so that the push rod 16 can squeeze the anti-touch plate 13. Since one side of the anti-touch plate 13 is an inclined surface, the anti-touch plate 13 will move due to the push of the push rod 16 and extend towards the inside of the receiving plate 11. When the subsequent engines slide onto the receiving plate 11, the anti-touch plate 13 will block them, preventing the two engines from contacting. By repeating the above operation, multiple engines can be separated by the anti-touch plate 13. When the pusher block 27 is used to push the engines, the situation where the pushed engine drives the adjacent engine to move due to friction will not occur, ensuring that the pusher block 27 can only push down one engine at a time. And since each anti-touch plate 13 corresponds to a digital mark 31, the engines in contact with the anti-touch plate 13 will also correspond to the digital mark 31. After the worker finds an engine whose problems can be solved by repair, record the corresponding number. When the cause analysis is completed, the recorded numbers can be uniformly input into the controller, and the controller will drive the pusher block 27 to push the engine at the position corresponding to the number, so that the movement trajectory of the pusher block 27 is relatively regular and the operation is simple.;
