Description

Technical Field

[0001] This utility model relates to the field of synchronous reducer testing fixtures, and is suitable for production line offline testing, specifically to a multi-station installation mechanism for reducer testing. Background Technology

[0002] Starting torque and transmission error are two important parameters among those related to speed reducers. Currently, speed reducers are tested using two separate test benches: a transmission error test bench and a starting torque test bench. However, both traditional test benches are horizontally positioned, meaning the two tests cannot be performed on the same bench. The reasons are as follows:

[0003] When testing the starting torque of a speed reducer, the drive motor and the input end of the speed reducer must be directly connected (except for the torque sensor), and there should be no other connecting shaft devices in between. Otherwise, the measured starting torque will contain the friction torque of other connecting shafts, affecting the measurement results. However, speed reducer transmission error requires measuring the rotation angles at the input and output ends of the speed reducer. Therefore, transmission error tests generally require setting up an angle encoder or other measuring device at the input end of the speed reducer to measure the rotation angle. This necessitates a shaft connection between the speed reducer and the drive motor, which is fundamentally different from the requirement of no connecting shaft device in the starting torque test. Therefore, the two tests cannot be performed on the same test bench.

[0004] Therefore, current methods for testing the starting torque and transmission error of speed reducers have the following problems:

[0005] 1. The installation process is cumbersome and inefficient. Currently, after completing one test, the installation needs to be readjusted before another test can be conducted, making it impossible to quickly install the speed reducer under test.

[0006] 2. The operation of the testing line is not automated or intelligent enough, and it cannot be integrated with the production line to perform synchronous testing in the automated production line.

[0007] It is evident that there is still room for improvement in the testing of speed reducers, especially in the installation and operation of the speed reducers under test. Optimization is needed to improve the ease of operation, integrate starting torque detection and transmission error detection, and enhance the automation and integration of the testing process. This should be combined with current production lines to improve production and testing efficiency. Therefore, a more reasonable technical solution is needed to address the technical problems existing in the current technology. Utility Model Content

[0008] To overcome at least one of the aforementioned defects, this utility model proposes a multi-station mounting mechanism for speed reducer testing. This mechanism keeps the speed reducer under test in a longitudinal position and sequentially performs the detection of starting torque and transmission error in the longitudinal position. This avoids frequent installation and disassembly, and continuous testing can be maintained by alternating between the working position, the test position, and the disassembly position. This mechanism can also be coordinated with the production line to improve overall efficiency.

[0009] To achieve the above objectives, the installation mechanism disclosed in this utility model can adopt the following technical solution:

[0010] A multi-station mounting mechanism for testing speed reducers includes a drive base, a pre-installed component on top of the drive base, and several mounting positions formed on the pre-installed component for connecting the speed reducer under test. A switching drive component is provided inside the drive base. The switching drive component is in transmission cooperation with the pre-installed component and drives the pre-installed component to switch the speed reducer under test to the test position.

[0011] The aforementioned installation station allows for continuous testing by vertically positioning the reducer under test, connecting it with pre-installed components, and rotating it horizontally to switch the position of the reducer under test. This improves the efficiency and convenience of reducer testing while also ensuring the reliability of reducer testing.

[0012] Furthermore, the pre-installed component, used to mount the reducer under test and switch its position, can be implemented in various ways, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the pre-installed component includes a pre-installed tray with several mounting positions for connecting the reducer under test. When using this solution, several mounting positions can be set around the perimeter of the pre-installed tray. By rotating the pre-installed tray and switching the positions of the mounting positions, the reducer under test can be switched to the testing position.

[0013] Furthermore, the mounting position is used to connect and fix the reducer under test. This structure helps to position and stabilize the reducer under test. Its structure is not limited to a single type; here, we propose an optimization and one feasible option: an embedded groove is formed at the mounting position, and a mounting ring is provided in the embedded groove. When adopting the above solution, the embedded groove can be constructed as an arc groove, and the mounting ring is placed at the edge of the embedded groove and protrudes above the groove, helping to connect and fix the reducer under test.

[0014] Furthermore, the embedded groove is also provided with a positioning pin that aligns with the reducer under test.

[0015] Furthermore, the drive base provides a supporting position and driving force to drive the pre-assembled components. Its structure is not uniquely limited; here, an optimization is proposed, and one feasible option is suggested: the drive base forms a closed mounting cavity, and the switching drive assembly is disposed inside the mounting cavity. The switching drive assembly includes a drive motor for rotating the pre-assembled tray, with the drive shaft of the drive motor extending upwards and driving the pre-assembled tray to rotate. With the above solution, the drive shaft of the drive motor can be directly shaft-connected to the pre-assembled tray, or it can be connected via a transmission structure.

[0016] Furthermore, to achieve the rotation of the pre-assembled tray, it can be driven by a corresponding drive mechanism. The structure is not uniquely limited; here, an optimization is proposed, and one feasible option is suggested: a positioning component is also provided below the pre-assembled tray. This positioning component includes several sensors and transmitters correspondingly arranged on the circumference. The sensors rotate synchronously with the pre-assembled tray, and the transmitter emits a signal. The change in signal from the sensors determines the current rotation angle of the pre-assembled tray. With this scheme, the drive motor can directly rotate the pre-assembled tray, or it can be driven by a transmission component. The transmitters are spaced apart in the rotation direction of the pre-assembled tray. For example, if four mounting positions are set, the mounting positions are evenly spaced and placed every 90°. Similarly, four sensors are also set, one every 90°. This scheme can accurately determine the rotation angle of the pre-assembled tray and accurately switch the reducer under test to the detection position.

[0017] Furthermore, when the drive motor cooperates with the pre-installed tray through the transmission structure and drives its rotation, the switching speed requirements of the pre-installed tray can be met. The transmission structure can adopt various schemes and is not limited to a single one. Here, we optimize and propose one feasible option: a transmission seat is installed below the pre-installed tray, and the transmission seat is driven to rotate by the drive motor. The pre-installed tray and the transmission seat rotate synchronously. A lifting guide mechanism and a lifting drive mechanism are provided 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 move directionally relative to the transmission seat. When adopting the above scheme, a gear pair can be installed in the transmission seat for transmission cooperation, or a belt drive structure, chain drive structure, etc., can be used for transmission cooperation.

[0018] Furthermore, there are multiple options for the connection between the transmission base and the drive motor, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the transmission base and the drive motor are connected by a transmission structure, where the transmission pair includes gear transmission, belt transmission, and chain transmission. When using this scheme, the drive motor drives the transmission base through the transmission pair, achieving speed reduction transmission.

[0019] Furthermore, to maintain the stability of the entire mounting mechanism, the structure of the drive seat can be optimized. Its structure is not limited to a single design; one feasible option is proposed here: several support pads are provided beneath the drive seat. When using this solution, the support pads are spaced apart along the edge of the drive seat to form stable support. The support pads can be elastic pads, or they can cooperate with the drive seat through elastic pads.

[0020] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in this utility model include:

[0021] This invention improves the structure of the speed reducer, maintaining its longitudinal orientation for subsequent starting torque and transmission error detection, eliminating the need for repeated disassembly and assembly on the same equipment. This improves the efficiency of speed reducer testing, avoids complex operations, and ensures the accuracy and reliability of test results. It enables faster and more efficient automated testing, thereby improving the production and processing efficiency of speed reducers. Attached Figure Description

[0027] The following description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this embodiment.

[0028] To address the significant limitations of existing speed reducer testing and installation stations, which require frequent disassembly and assembly, leading to inconvenient equipment use and low operational efficiency, the following embodiments are optimized to overcome the shortcomings of the prior art.

[0029] Example

[0030] like Figure 1 , Figure 2 As shown, this embodiment provides a multi-station mounting mechanism for speed reducer testing, including a drive base, a pre-installed component on the top of the drive base, and a plurality of mounting positions 2 formed on the pre-installed component for connecting the speed reducer to be tested; a switching drive component is provided inside the drive base, the switching drive component is in transmission cooperation with the pre-installed component and is used to drive the pre-installed component to switch the speed reducer to be tested to the test position.

[0031] The installation station disclosed in this embodiment vertically sets up the speed reducer under test, connects it with pre-installed components, and rotates horizontally to switch the position of the speed reducer under test, thereby enabling continuous testing, improving the testing efficiency and convenience of the speed reducer, and ensuring the reliability of the speed reducer test.

[0032] The pre-installed component is used to mount the reducer under test and switch its position. Various methods can be used to achieve this, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the pre-installed component includes a pre-installed tray 1, which has several mounting positions 2 for connecting the reducer under test. When using the above method, several mounting positions 2 can be set around the perimeter of the pre-installed tray 1. By rotating the pre-installed tray 1 and switching the position of the mounting positions 2, the reducer under test can be switched to the testing position.

[0033] Mounting position 2 is used to connect and fix the reducer under test. This structure helps to position and stabilize the reducer under test. Its structure is not limited to a single type; this embodiment optimizes and adopts one feasible option: an embedded groove is formed at mounting position 2, and a mounting ring 3 is provided at the embedded groove. When using the above scheme, the embedded groove can be constructed as an arc groove, and the mounting ring 3 is located at the edge of the embedded groove and extends beyond the groove, helping to connect and fix the reducer under test.

[0034] In this embodiment, a positioning pin 4 is also provided at the embedded groove to align with the reducer under test.

[0035] The drive base provides a supporting position and driving force to drive the pre-assembled components. Its structure is not uniquely limited; this embodiment optimizes and adopts one feasible option: the drive base forms a closed mounting cavity, and the switching drive assembly is disposed inside the mounting cavity. The switching drive assembly includes a drive motor 8 for rotating the pre-assembled tray 1. The drive shaft of the drive motor 8 extends upwards and drives the pre-assembled tray 1 to rotate. With the above solution, the drive shaft of the drive motor 8 can be directly shaft-connected to the pre-assembled tray 1, or it can be connected via a transmission structure.

[0036] To achieve the rotation of the pre-installed tray 1, it can be driven by a corresponding drive mechanism. The structure is not uniquely limited; this embodiment optimizes the process and adopts one feasible option: a positioning component is also provided below the pre-installed tray 1. This positioning component includes several sensors 5 and transmitters 6 arranged circumferentially. The sensors 5 rotate synchronously with the pre-installed tray 1, and the transmitters 6 emit signals. The change in signal generated by the transmitters 5 determines the current rotation angle of the pre-installed tray 1. With this scheme, the drive motor 8 can directly rotate the pre-installed tray 1, or it can be driven by a transmission component. The transmitters 6 are spaced apart in the rotation direction of the pre-installed tray 1. For example, if four mounting positions 2 are provided, they are evenly spaced and placed every 90°. Similarly, four sensors 5 are also provided, placed every 90°. This scheme can accurately determine the rotation angle of the pre-installed tray 1 and accurately switch the speed reducer under test to the detection position.

[0037] When the drive motor 8 cooperates with the pre-installed tray 1 through the transmission structure and drives it to rotate, the switching speed requirements of the pre-installed tray 1 can be met. The transmission structure can adopt various schemes, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: a transmission seat 7 is provided below the pre-installed tray 1. The transmission seat 7 is driven to rotate by the drive motor 8, and the pre-installed tray 1 and the transmission seat 7 rotate synchronously. A lifting guide mechanism 9 and a lifting drive mechanism 10 are provided between the pre-installed tray 1 and the transmission seat 7. The lifting drive mechanism 10 and the lifting guide mechanism 9 are used to drive the pre-installed tray 1 to move up and down relative to the transmission seat 7 in a directional manner. When adopting the above scheme, a gear pair can be provided in the transmission seat 7 for transmission cooperation, or a belt drive structure, chain drive structure, etc., can be provided for transmission cooperation.

[0038] There are multiple options for the cooperation between the transmission seat 7 and the drive motor 8, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the transmission seat 7 and the drive motor 8 are connected by a transmission structure, and the transmission pair includes gear transmission, belt transmission, and chain transmission. When the above scheme is adopted, the drive motor 8 drives the transmission seat 7 through the transmission pair, which can realize speed reduction transmission.

[0039] To maintain the stability of the entire mounting mechanism, the structure of the drive seat can be optimized. Its structure is not limited to a single design; this embodiment optimizes the design and adopts one feasible option: several support pads are provided below the drive seat. When using the above solution, the support pads are spaced apart along the edge of the drive seat to form stable support; the support pads can be elastic pads, or they can cooperate with the drive seat through elastic pads.
