[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0019] The present invention proposes a precision reducer detector adapter. Figure 1 is a structural schematic diagram of a precision reducer detector adapter provided by an embodiment of the present invention, Figure 21 is a schematic diagram of a structure in which a precision reducer detector adapter is connected to a reducer to be tested, provided by an embodiment of the present invention. Figure 3 This is a structural schematic diagram of a precision reducer detector adapter provided by an embodiment of the present invention installed on a detector, see Figure 1-Figure 3 , adapters include: An adapter housing 6, an adapter internal structure 2, an adapter upper end external structure 1 and an adapter lower end external structure 3; The internal structure 2 of the adapter is used to install the reducer 5 under test. The internal structure 2 of the adapter is positioned and connected with the mounting structure of the reducer 5 under test. The internal structure 2 of the adapter and the mounting structure of the reducer 5 under test are paired with each other, so that the mounting reference of the reducer 5 under test can be transmitted to both ends through the internal structure 2 of the adapter.

[0020] The external structure 1 at the upper end of the adapter is the upper end cover of the adapter housing used for positioning and connecting with the input terminal 8 of the detector. The external structure 1 at the upper end of the adapter is positioned in pairs with the input terminal 8 of the detector, and is used to transfer the installation reference of the reducer 5 to the input terminal 8 of the detector as the measurement reference of the input terminal 8 of the detector.

[0021] The external structure 3 at the lower end of the adapter is the lower end cover of the adapter housing used for positioning and connecting with the output terminal 9 of the detector. The external structure 3 at the lower end of the adapter is positioned in pairs with the output terminal 9 of the detector, and is used to transfer the installation reference of the reducer 5 to the output terminal 9 of the detector as the measurement reference of the output terminal 9 of the detector.

[0022] Furthermore, when the test torque is small, the external structure 1 at the upper end of the adapter is positioned and connected to the input end 8 of the detector by using a combination of stopper positioning and five-point positioning of the flange end face; The external structure 3 at the lower end of the adapter is positioned and connected to the output end 9 of the detector by using a combination of stopper positioning and flange end face five-point positioning.

[0023] Specifically, the input and output components are positioned and connected through five-point positioning at the upper and lower ends, the coaxiality requirements are further guaranteed, the reference transfer of the input and output ends is realized, and the reference is transferred from the middle to both sides. Such a design can use the installation reference of the reducer under test as the measurement reference of the instrument, and transfer it to the input and output measurement components through five-point positioning on both sides.

[0024] Furthermore, Figure 4 1 is a structural schematic diagram of a precision reducer detector adapter provided by an embodiment of the present invention and provided with an end stop plate. Figure 5 This is a structural schematic diagram of a precision reducer detector adapter provided by an embodiment of the present invention connected to the detector through an end stop plate, see Figure 4 and Figure 5, when the test torque is large, the external structure 1 at the upper end of the adapter is positioned and connected to the input end 8 of the detector through the first end stop plate; The external structure 3 at the lower end of the adapter is positioned and connected to the output end 9 of the detector through the second end stop plate; The first end stop plate includes a first upper end stop plate 12 and a first lower end stop plate 10; The second end stop plate includes a second upper end stop plate 11 and a second lower end stop plate 13 .

[0025] Furthermore, the first upper stop plate 12 and the first lower stop plate 10 are both multi-tooth indexing plates, and the first upper stop plate 12 and the first lower stop plate 10 are mating parts to each other; The second upper stop plate 11 and the second lower stop plate 13 are both multi-tooth indexing plates, and the second upper stop plate 11 and the second lower stop plate 13 are mating parts of each other.

[0026] Furthermore, the first end stop plate and the second end stop plate are colinear with the mounting axis of the reducer 5 to be measured. The automatic centering performance of the dual multi-tooth indexing discs of the adapter and the detector ensures that the cylindrical body of the adapter is coaxial with the cylindrical brackets of the input end 8 and the output end 9 of the detector. The end faces of the adapter connected to the detector are matched with multi-tooth indexing discs, and the axial pressure formed by the deadweight of the input end 8 of the detector and the deadweight of the input end 8 of the detector and the adapter is used to ensure the efficient transmission of the measuring torque of the detector, while avoiding the weak rigidity sliding mechanism of the detector from participating in the torque transmission, effectively improving the overall torsional rigidity of the detector.

[0027] Further, the first lower stop plate 10 is positioned and connected to the upper external structure 1 of the adapter, the first upper stop plate 12 is positioned and connected to the input end 8 of the detector, and the first upper stop plate 12 and the first lower stop plate 10 are positioned at six points by tooth-groove cooperation; the tooth-groove cooperation needs to meet the accuracy requirements of the reference transmitted to the input end 8 of the detector; The second upper stop plate 11 is positioned and connected to the external structure 3 at the lower end of the adapter, and the second lower stop plate 13 is positioned and connected to the output end 9 of the detector. The second upper stop plate 11 and the second lower stop plate 13 are positioned at six points through tooth-groove cooperation; the tooth-groove cooperation needs to meet the accuracy requirements of the reference transmitted to the low-speed end.

[0028] Specifically, the close fit between the teeth and the grooves can effectively limit the relative movement between the two components, including not only axial displacement, but also rotation and translation, etc. Six-point positioning, that is, constraining the six degrees of freedom of the adapter and the detector, including three translational degrees of freedom X, Y, and Z, and three rotational degrees of freedom around the X-axis, Y-axis, and Z-axis, thereby improving the accuracy of the relative position between components and ensuring the overall stability and accuracy of the assembly.

[0029] Furthermore, the adapter also includes: The input end is connected to the shaft 4 and the output end is connected to the shaft 7; The input end connecting shaft 4 is used to connect the transmission input end of the reducer 5 to be measured and the input end 8 of the detector to transmit the measuring shaft system; The output end connecting shaft 7 is used to connect the transmission output end of the reducer 5 to be measured and the transmission measuring shaft system of the output end 9 of the detector.

[0030] The present invention designs the adapter and the mounting structure of the reducer under test to be a pair of parts, installs the reducer under test inside the adapter through the mounting structure, and then connects the input end and the output end of the reducer under test to the input end measurement system and the output end measurement system of the detector through connecting shafts corresponding to the model, thereby realizing the process of transferring the mounting reference of the reducer under test as the measurement reference of the detector to the test components at both ends of the instrument. For the detector, the above-mentioned whole and the instrument form a standardized unified connection structure, thereby ensuring the coaxiality accuracy of the overall structure of the test system; further, by arranging the end stop plate to connect the adapter to the detector, when the test torque is large or a large reducer is tested, the accuracy of the coaxiality and reference transmission can be guaranteed, and at the same time, it has good torsion resistance and is not easy to slip, thereby improving the accuracy and precision of the measurement results, and avoiding the difference between the measurement results of the comprehensive performance of the reducer under test and the actual working performance.

[0031] Figure 6 is a flow chart of a method for using a precision reducer detector adapter provided by an embodiment of the present invention, which is implemented based on the above-mentioned precision reducer detector adapter, see Figure 5 , specifically including the following steps: S1. Position and connect the mounting structure of the reducer 5 to the internal structure 2 of the adapter, connect the transmission input end of the reducer 5 to the input end connecting shaft 4, and connect the transmission output end of the reducer 5 to the output end connecting shaft 7 to form a combination to be tested.

[0032] S2. Place the assembly to be tested on the preparation station of the detector, and use the instrument auxiliary motion mechanism to realize the positioning, connection and fixation of the assembly to be tested and the measuring component at the input end 8 and the measuring component at the output end 9 of the detector, and perform the detection process.

[0033] S3. During the testing process, another adapter is synchronously installed with the next reducer 5 to be tested according to the method of S1 to form the next assembly to be tested.

[0034] S4, after the detection of the current assembly to be tested is completed, the current assembly to be tested is replaced with the assembled next assembly to be tested, and the detection process of the next assembly to be tested is performed.

[0035] In addition, the present invention carries out the loading and unloading of the reducer under test and the online testing process of the testing instrument in parallel, which can realize the rapid clamping of the reducer under test on the instrument, ensure reliable connection, and ensure the installation accuracy of the reducer under test on the instrument, realize the reusable use of the adapter, and greatly improve the testing efficiency of the instrument. If multiple adapters are used in turn, the installation time of the reducer can be completely separated from the measuring time of the instrument, the utilization rate of the instrument can be greatly improved, and it becomes possible to realize full inspection of large quantities of products.
