Description

Technical Field

[0001] The invention relates to the technical field of synchronous reducer testing tooling, which is suitable for off-line detection of an assembly line, and in particular to a system and method for testing starting torque and transmission error of a reducer. Background Art

[0002] Starting torque and transmission error are two important parameters in the reducer related parameters. At present, the reducer uses two test benches to test the starting torque and transmission error, namely: transmission error test bench and starting torque test bench, and the two test items cannot be completed on the same test bench. The reasons are as follows:

[0003] When testing the starting torque of the reducer, the drive motor and the input end of the reducer must be directly connected (except for the torque sensor), and there must be no other connecting shaft devices in the middle, otherwise the measured starting torque will contain the friction torque of other connecting shafts, affecting the measurement effect. The transmission error of the reducer requires measuring the rotation angle of the input and output ends of the reducer. Therefore, the general transmission error test requires setting up an angle encoder or other measuring device at the input end of the reducer to measure the rotation angle. This requires setting up a shaft connection between the reducer and the drive motor, which is essentially different from the limitation of not setting up a connecting shaft device in the starting torque test, so the two tests cannot be completed on the same test bench.

[0004] Therefore, the current reducer starting torque test and transmission error test have the following problems:

[0005] 1. Starting torque and transmission error have different requirements for the test matching structure, which requires more test equipment. There is no equipment that can take both tests into account.

[0006] 2. Currently, after completing a test, the reducer needs to be readjusted before another test can be performed, and the reducer being tested cannot be installed quickly.

[0007] 3. The operation of the test line is not automated and intelligent enough, and it cannot be connected to the production line, and cannot adapt to the automatic production of the assembly line for synchronous testing.

[0008] It can be seen that there is still room for improvement in the detection of reducers. Optimization should be carried out to improve the convenience of reducer detection, integrate starting torque detection and transmission error detection, and improve the automation and integration of detection. It should be coordinated with the current production line to improve the efficiency of production and detection. Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the existing technology. Summary of the invention

[0009] In order to overcome at least one of the defects mentioned above, the present invention proposes a system and method for testing the starting torque and transmission error of a reducer. By improving the structure of the detection equipment, the reducer to be tested is kept in a longitudinal position, and the starting torque and transmission error detection are completed in sequence in the longitudinal position, thereby avoiding frequent installation and disassembly. Continuous detection can be maintained by alternating between the working position, the position to be tested and the disassembly position, thereby coordinating with the production line and improving the overall efficiency.

[0010] In order to achieve the above purpose, the test system disclosed in the present invention can adopt the following technical solutions:

[0011] A speed reducer starting torque and transmission error testing system, comprising:

[0012] Pre-installed components are used to install the reducers to be tested and transfer the reducers to be tested to the testing position one by one;

[0013] The detection component includes a transmission error detection component and a starting torque detection component; the transmission error detection component includes a transmission detection motor and an angle encoder component for detecting transmission error, the angle encoder is used to align with the input end and output end of the detection reducer and is driven by the transmission motor; the starting torque detection component includes a torque sensor and a torque detection motor for detecting starting torque, the torque sensor is used to align with the input shaft of the detection reducer and is driven by the torque detection motor;

[0014] The lifting component is used to drive the detection component to lift and connect or separate with the reducer to be tested; the lifting component includes a main lifting seat and a secondary lifting seat arranged on the main lifting seat, and the transmission error detection component and the starting torque detection component are respectively arranged on the main lifting seat and the secondary lifting seat.

[0015] The above-disclosed test system realizes the detection of starting torque by vertically setting the reducer to be tested and connecting the shaft in the longitudinal direction; without disassembling the reducer, the connection structure for starting torque detection is disconnected and the connection structure for transmission error detection is connected, thereby realizing the continued testing of transmission error. Using a set of equipment can realize both the detection of starting torque and the detection of transmission error, which improves the test efficiency and convenience of the reducer and also ensures the reliability of the reducer test.

[0016] Furthermore, the pre-installed component is used to install the reducer to be tested and drive the switch of its position. It can be implemented by various schemes, and its structure is not limited to a single one. Here, it is optimized and one of the feasible options is proposed: the pre-installed component includes a pre-installed tray, and the pre-installed tray is provided with a plurality of installation positions for connecting the reducer to be tested. When the above scheme is adopted, a plurality of installation positions can be set around the pre-installed tray, and the pre-installed tray rotates and switches the position of the installation position so that the reducer with detection can be switched to the detection position.

[0017] Furthermore, in order to realize the rotation of the pre-installed tray, it can be driven by a corresponding driving mechanism, and its structure is not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: a switching driving assembly is arranged under the pre-installed tray, and the switching driving assembly includes a driving motor for driving the pre-installed tray to rotate; a positioning assembly is also arranged, and the positioning assembly includes a number of sensors and transmitters arranged correspondingly on the circumference, the sensors rotate synchronously with the pre-installed tray, and the transmitter sends a signal and determines the current angle of rotation of the pre-installed tray according to the signal change caused by the signal encountering the sensor. When the above scheme is adopted, the driving motor can drive the pre-installed tray to rotate directly, or it can be driven by a transmission member; the transmitter is arranged at intervals in the rotation direction of the pre-installed tray. For example, when four installation positions are set, the installation positions are evenly spaced and set at every 90°. Similarly, the sensors are also set to four correspondingly, and set at every 90°. This scheme can accurately judge the angle of rotation of the pre-installed tray and accurately switch the reducer to be tested to the detection position.

[0018] Furthermore, when the driving motor cooperates with the pre-installed tray through the transmission structure and drives it to rotate, the switching speed requirement of the pre-installed tray can be met. The transmission structure can adopt a variety of schemes, and its structure is not limited to a single one. Here, it is optimized and one of the feasible options is proposed: a transmission seat is arranged under the pre-installed tray, and the transmission seat is driven to rotate by the driving motor. The pre-installed tray and the transmission seat rotate synchronously, and a lifting guide mechanism and a lifting drive mechanism are arranged between the pre-installed tray and the transmission seat. The lifting drive mechanism and the lifting guide mechanism are used to drive the pre-installed tray to lift and lower relative to the transmission seat. When the above scheme is adopted, a gear pair can be arranged in the transmission seat for transmission cooperation, and a belt transmission structure, a chain transmission structure, etc. can also be arranged for transmission cooperation.

[0019] Furthermore, the main lifting seat and the auxiliary lifting seat respectively drive the error detection component and the starting torque detection component to move, and the coordination method can adopt a variety of schemes, and its structure is not limited to a single one. Here, it is optimized and one of the feasible options is proposed: the main lifting seat is provided with a first mounting seat, and the angle encoder component includes an input end angle encoder component, and the input end angle encoder component is arranged on the first mounting seat and is used to connect and cooperate with the input shaft of the reducer to be tested; the main lifting seat is also provided with a second mounting seat, and the transmission detection motor is arranged on the second mounting seat and cooperates with the input end angle encoder component. When the above scheme is adopted, the first mounting seat and the second mounting seat are fixedly connected to the main lifting seat and rise and fall synchronously with the main lifting seat, so the main lifting seat can drive the input end angle encoder component to rise and fall and dock or separate with the input end of the reducer to be tested.

[0020] Furthermore, when the transmission error is detected, it is necessary to perform angle deflection detection on both the input and output ends of the reducer to be tested, and then the total transmission error can be detected. This can be achieved through a variety of schemes, and a variety of detection structures are formed accordingly. The structure is not limited to a single one. Here, it is optimized and one of the feasible options is proposed: the angle encoder component also includes an output angle encoder component, which is located below the input angle encoder component and is used to connect and match the output shaft of the reducer to be tested; the output angle encoder component is driven by the third lifting mechanism and docked with or separated from the output shaft. When the above scheme is adopted, the output angle encoder component can be docked with or separated from the output shaft of the reducer to be tested under the drive of the third lifting mechanism, thereby cooperating with the input angle encoder component to realize the detection of transmission error.

[0021] Furthermore, the input angle encoder component provides driving power to the reducer to be tested, thereby realizing the rotation of the internal shaft of the reducer and realizing the detection of transmission error. The composition structure of the input angle encoder component can be constructed in various forms, and its structure is not limited to a single one. Here, it is optimized and one of the feasible options is proposed: the input end angle encoder component includes a transmission sleeve arranged on the second mounting seat, the transmission sleeve is driven by the transmission detection motor and connected to the input end angle encoder, and the input end angle encoder is connected to the input shaft of the reducer to be tested. When the above scheme is adopted, the transmission sleeve is coaxially matched with the input end angle encoder and rotates. When docking with the input shaft of the reducer, the power can be accurately transmitted to the input shaft and drive it to rotate.

[0022] Furthermore, the auxiliary lifting seat is used to drive the starting torque detection component to move and face the detection reducer or separate from it, and at the same time does not interfere with the transmission error detection component. It can be implemented in a variety of ways, and its structure is not limited to a single one. Here, it is optimized and one of the feasible options is proposed: the auxiliary lifting seat is correspondingly arranged above the first mounting seat. When the auxiliary lifting seat drives the torque sensor to descend, the connecting shaft at the torque sensor passes through the input end angle encoder component and is coaxially matched with the input shaft of the reducer to be tested. The connecting shaft and the input end angle encoder component are separately connected to the reducer to be tested. When the above scheme is adopted, a lifting slide rail is formed between the auxiliary lifting seat and the main lifting seat, thereby realizing the lifting action.

[0023] Furthermore, the reducer to be tested can be fixed on a pre-installed pallet for testing. In order to improve stability and reliability, a separate detection structure can also be set up, and the reducer to be tested can be transferred to the detection structure for fixing before testing. Specifically, it can be new through a variety of schemes, and its structure is not limited to a single one. Here, it is optimized and one of the feasible options is proposed: it also includes a test seat, and a test position that cooperates with the reducer to be tested is formed on the test seat; the test seat is also provided with a number of fixing mechanisms for assisting in fixing the reducer to be tested. When the above scheme is adopted, the test seat includes a support table for supporting the reducer to be tested, and the test position on the support table cooperates with the fixing mechanism to fix the reducer, and it can also remain stable and reliable when the reducer rotates. In some schemes, the fixing mechanism can adopt a fixed pressure arm, and the fixed pressure arm is driven by hydraulic pressure or by pneumatic drive, and can also be driven by a mechanical transmission pair.

[0024] The above discloses the components of the test system. The present invention also discloses a method for performing a specific test using the above test system, which is described below.

[0025] A method for testing the starting torque and transmission error of a reducer, using the test system described above, comprises:

[0026] Place the reducer to be tested on the pre-installed assembly, and transfer the reducer to be tested to the testing position through the pre-installed assembly;

[0027] Lower the reducer to be tested from the pre-assembled assembly and fix it to the test seat;

[0028] Lower the starting torque detection component and make the connecting shaft dock with the input shaft of the reducer to be tested, and start the torque detection motor to detect the starting torque; after the detection is completed, lift the starting torque component to separate the connecting shaft from the input shaft of the reducer to be tested;

[0029] The transmission error detection component is docked with the reducer to be tested, including lowering the input end angle encoder component and docking it with the input end of the reducer to be tested, and raising the output end angle encoder component and docking it with the output end of the reducer to be tested; starting the transmission motor to perform transmission error detection, and separating the transmission error detection component from the reducer to be tested after the detection is completed;

[0030] Lift the tested reducer and assemble it to the pre-installed assembly, switch it to the disassembly position and then dismantle it. At the same time, switch the other reducer to be tested to the detection position and repeat the above operation.

[0031] Compared with the prior art, some beneficial effects of the technical solution disclosed in the present invention include:

[0032] The present invention improves the setting structure of the reducer, maintains its longitudinal setting and successively performs starting torque detection and transmission error detection, thereby eliminating repeated disassembly and assembly operations on the same device. This improves the efficiency of reducer detection, avoids complex operations, and also ensures the accuracy and reliability of the reducer detection results. The system can be docked with the production line of the reducer to achieve faster and more efficient automated detection, thereby improving the production and processing efficiency of the reducer.

[0050] Preferably, in this embodiment, the testing system further comprises a base 6 and a frame 7 , the pre-installed component 5 is arranged on the base 6 , and the detection component and the lifting component are arranged on the frame 7 .

[0051] The test system disclosed in this embodiment realizes the detection of starting torque by vertically setting the reducer 8 to be tested and connecting the shaft in the longitudinal direction; without disassembling the reducer, the connection structure for starting torque detection is disconnected and the connection structure for transmission error detection is connected, thereby realizing the continued test of transmission error. Using a set of equipment can realize the detection of starting torque and transmission error, which improves the test efficiency and convenience of the reducer and also ensures the reliability of the reducer test.

[0052] The pre-installed component 5 is used to install the reducer 8 to be tested and drive the switching of its position. It can be implemented by various schemes, and its structure is not limited to a single one. This embodiment is optimized and adopts one of the feasible options: the pre-installed component 5 includes a pre-installed tray 501, and the pre-installed tray 501 is provided with a plurality of mounting positions 502 for connecting the reducer 8 to be tested. When the above scheme is adopted, a plurality of mounting positions 502 can be set around the pre-installed tray 501, and the pre-installed tray 501 rotates and switches the position of the mounting position 502 so that the reducer with detection can be switched to the detection position.

[0054] In order to realize the rotation of the pre-installed tray 501, it can be driven by a corresponding driving mechanism, and its structure is not limited to a single one. This embodiment is optimized and adopts one of the feasible options: a switching driving assembly is arranged below the pre-installed tray 501, and the switching driving assembly includes a driving motor 508 for driving the pre-installed tray 501 to rotate; a positioning assembly is also arranged, and the positioning assembly includes a plurality of sensors 505 and a transmitter 506 correspondingly arranged on the circumference, the sensor 505 rotates synchronously with the pre-installed tray 501, and the transmitter 506 sends a signal and determines the current rotation angle of the pre-installed tray 501 according to the signal change caused by the signal encountering the sensor 505. When the above scheme is adopted, the driving motor 508 can drive the pre-installed tray 501 to rotate directly, or it can be driven by a transmission member; the transmitter 506 is arranged at intervals in the rotation direction of the pre-installed tray 501, for example, when four installation positions 502 are arranged, the installation positions 502 are evenly spaced and arranged every 90°, and similarly, the sensor 505 is also correspondingly arranged to be four, and arranged every 90°. This solution can accurately determine the angle through which the pre-installed tray 501 has been rotated, and accurately switch the reducer 8 to be tested to the detection position.

[0055] When the driving motor 508 cooperates with the pre-installed tray 501 through the transmission structure and drives it to rotate, the switching speed requirement of the pre-installed tray 501 can be met. The transmission structure can adopt a variety of schemes, and its structure is not limited to the only one.

The lifting drive mechanism 510 and the lifting guide mechanism 509 are used to drive the pre-installed tray 501 to lift and lower relative to the transmission seat 507. When the above scheme is adopted, a gear pair can be arranged in the transmission seat 507 for transmission cooperation, and a belt transmission structure, a chain transmission structure, etc. can also be arranged for transmission cooperation.

[0056] The main lifting seat 1 and the auxiliary lifting seat 2 drive the error detection component and the starting torque detection component 3 to move respectively. The coordination method can adopt a variety of schemes, and its structure is not limited to a single one. This embodiment is optimized and adopts one of the feasible options: the main lifting seat 1 is provided with a first mounting seat 405, and the angle encoder component includes an input end angle encoder component 402, and the input end angle encoder component 402 is arranged on the first mounting seat 405 and is used to connect and cooperate with the input shaft of the reducer 8 to be tested; the main lifting seat 1 is also provided with a second mounting seat 404, and the transmission detection motor 403 is arranged on the second mounting seat 404 and cooperates with the input end angle encoder component 402.

[0059] The auxiliary lifting seat 2 is used to drive the starting torque detection component 3 to move and face the detection reducer to be detected or separate from it, and does not interfere with the transmission error detection component 4. It can be realized by various schemes, and its structure is not limited to a single one. This embodiment is optimized and adopts one of the feasible options: the auxiliary lifting seat 2 is correspondingly arranged above the first mounting seat 405. When the auxiliary lifting seat 2 drives the torque sensor 302 to descend, the connecting shaft 303 at the torque sensor 302 passes through the input end angle encoder component 402 and is coaxially matched with the input shaft of the reducer 8 to be tested.
