[0059] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0060] The terms “first”, “second”, and the like in the embodiments of the present application are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. In addition, the terms “include” and “have” and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device including a series of steps or units does not necessarily limit to only those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to the process, method, product, or device. In addition, “and / or” is used in the present application to represent at least one of the connected objects, for example, A and / or B and / or C represents 7 cases including A alone, B alone, C alone, A and B both exist, B and C both exist, A and C both exist, and A, B and C all exist.

[0061] Please refer to Figure 1 , Figure 1 is a structural schematic diagram of a driving device test tool provided by an embodiment of the present application. The driving device test tool is used to test performance parameters of a driving device under test 60, wherein the driving device under test 60 can include a motor under test or a joint module under test. When the driving device under test 60 includes a motor under test, and when the motor under test is applied to a robot, the motor under test can serve as a component of the joint module, and the joint module can be a key component of a power system of the robot, and the performance of the joint module directly affects the motion ability of the robot.

[0062] The test tool includes a stall test mode for testing stall parameters of the driving device under test and a counter drive test mode for testing counter drive parameters of the driving device under test. The stall parameters and the counter drive parameters can be collectively referred to as performance parameters, and are specifically defined as follows:

[0063] The stall test mode refers to a test mode for detecting various performance parameters of the driving device under test when the driving device under test is in a stall state. The stall refers to that the driving device under test is prevented from rotating by an external resistance after being powered on. The stall state refers to a state in which the driving device under test is maintained in a non-rotating state under the action of the external resistance after being powered on. The performance parameters can include torque of the driving device under test, and the specific content is not limited. The external resistance can come from a drag support plate or a drag driving device. According to different external resistances, the stall test mode can be divided into a first stall test mode and a second stall test mode. For example, by setting a connection mode, the output end of the driving device under test can be fixedly connected with the drag support plate, so as to provide the external resistance by the drag support plate. When the external resistance is provided by the drag support plate, the stall test mode of the driving device test tool can be the first stall test mode. For another example, by setting a connection mode, the output end of the drag driving device is fixedly connected with the output end of the driving device under test, so as to provide the external resistance by the drag driving device. When the external resistance is provided by the drag driving device, the stall test mode of the driving device test tool can be the second stall test mode, and the drag driving device can refer to a device such as a motor whose rotating direction of the output end is opposite to that of the driving device under test.

[0064] The backdrive test mode, also known as the dynamic friction test mode, refers to a test mode that detects the friction and mechanical damping corresponding to the tested driving device when it is in the backdrive state and is driven to rotate by an external driving force (such as another driving device or manually by the user). Among them, "backdrive" actually reflects the passive drive when the joint module is not working. The backdrive state refers to the state when the tested driving device is powered off and not working and is driven by an external driving force. The backdrive force parameter can be the external driving torque (which can be called backdrive torque) or the external driving force required to drive the tested driving device to start rotating.

[0065] like Figure 1 As shown, the driving device test fixture includes: a base 10, a support plate 20 for the driving device under test, a pair support plate 30 and a detection sensor 50. The support plate 20 for the driving device under test and the pair support plate 30 are both arranged on the base 10. The support plate 20 for the driving device under test is used to set the driving device under test 60. The detection sensor 50 is arranged between the output end of the driving device under test 60 and the pair support plate 30, and is used to detect the performance parameters of the driving device under test.

[0066] In an embodiment of the present application, a drive device test fixture is provided for detecting performance parameters of a drive device 60. The specific types of the performance parameters are not limited herein, and the performance parameters may include torque, driving force, and the like.

[0067] Optionally, when the tested driving device 60 is powered on and the output end of the tested driving device 60 is connected to the drag support plate 30 through the detection sensor 50, the resistance provided by the drag support plate 30 causes the tested driving device 60 to maintain non-rotation, even when the tested driving device 60 is in a stalled state, thereby detecting various parameters of the tested driving device 60 when it is in a stalled state through the detection sensor 50. The specific content of the above parameters is not limited, for example: the parameters may include torque, etc.

[0068] Optionally, when the tested driving device 60 is not powered on, the tested driving device 60 can be driven to rotate by an external force. In this way, when the driving device test fixture is in the reverse drive test mode, the performance parameters of the tested driving device 60 in the reverse drive state can be detected, and the above-mentioned external force can be an external force manually applied by the user or an external force applied by other driving devices.

[0069] Optionally, the detection sensor 50 can be a sensor with a parameter display function, that is, the test parameters are displayed through a display screen on the detection sensor 50, or alternatively, in the case of a detection sensor 50 without a parameter display function, the detection sensor 50 can be connected with a display device through a data line or a wireless communication mode to display the test parameters through the display device. In this way, the diversity of the detection sensor 50 can be increased, and at the same time, the display mode of the test parameters can be diversified. And the reason for adopting the wireless communication mode is that some detection sensors with display screens or rotating with the coupling are prone to data line winding, and thus are not suitable for data line connection communication.

[0070] As an optional embodiment, the driving device test tool further comprises a second coupling 80 arranged between the detection sensor 50 and the counter support plate 30. As shown in Table 1 below, the test mode of the driving device test tool can be switched based on adjusting the connection or separation of the second coupling 80 and the counter support plate 30.

[0071] Table 1

[0072]

[0073] As shown in the scheme of No. 1 in Table 1 above, the second coupling 80 is connected with the counter support plate 30 to form the first stall test mode of the driving device test tool, that is, in this case, the first stall test mode of the driving device test tool can be formed without the counter driving device 40, and the connection strength of the second coupling 80 and the counter support plate 30 is higher. Thus, a driving device test tool for detecting the performance parameters of the measured driving device 60 in the stall state is provided.

[0074] It should be noted that the above driving device test tool can perform stall test on the measured driving device, but since many performance parameters of the measured driving device need to be detected, in addition to the performance parameters in the stall state, other performance parameters in the non-stall state also need to be detected, for example, the performance parameters of the measured driving device in the counter state, such as counter torque. When the performance parameters of the measured driving device in the counter state need to be detected, the corresponding test tool needs to be replaced, which will lead to an increase in test cost. It can be seen that there is currently a lack of a driving device test tool that can detect the performance parameters of the measured driving device in different states without the need to replace the test tool or test tool components.

[0075] As an optional implementation, the driving device test tool further comprises a tow driving device 40 arranged on the tow support plate 30 and fixed by fasteners. The second coupling 80 is connected with the output end of the tow driving device 40. In this case, the driving device test tool can realize the stall test mode and the counter drive test mode through the tow driving device 40. Specifically, the test mode of the driving device test tool can be switched by adjusting the connection or separation of the second coupling 80 and the tow support plate 30.

[0076] As shown in the scheme of Table 1 No. 2, the second coupling 80 is connected with the tow support plate 30, the measured driving device 60 is powered on, and the driving device test tool is in the stall test mode regardless of whether the tow driving device 40 is powered on or not and regardless of the ratio of the output power of the tow driving device 40 to the measured driving device 60 (i.e., no requirement thereon).

[0077] As shown in the scheme of Table 1 No. 3, the second coupling 80 is separated from the tow support plate 30, the measured driving device 60 is powered off, the tow driving device 40 is powered on, and the driving device test tool is in the counter drive test mode regardless of the ratio of the output power of the tow driving device 40 to the measured driving device 60 (i.e., no requirement thereon).

[0078] As shown in the scheme of Table 1 No. 4, the second coupling 80 is separated from the tow support plate 30, the measured driving device 60 is powered on, the tow driving device 40 is powered on, and the driving device test tool is in the counter drive test mode when the ratio of the output power of the tow driving device 40 to the measured driving device 60 is greater than 1.

[0079] The schemes shown in Table 1 Nos. 2 and 3 above indicate that the test mode of the driving device test tool can be switched by adjusting the connection or separation of the second coupling 80 and the tow support plate 30.

[0080] The schemes shown in Table 1 Nos. 3 and 4 above indicate that when the second coupling 80 is separated from the tow support plate 30, the test mode of the driving device test tool can be switched by adjusting the power-on and power-off of the measured driving device 60.

[0081] The schemes shown in Table 1 No. 2 and No. 4 above indicate that, in the case that the ratio of the output power of the drag driving device 40 to the output power of the measured driving device 60 is greater than 1, the driving device test tool can be switched from one locked-rotor test mode (i.e., referred to as a first locked-rotor test mode) to another locked-rotor test mode (i.e., referred to as a second locked-rotor test mode) by adjusting the connection or separation of the second coupling 80 and the drag support plate 30. The schemes shown in Table 1 No. 2 and No. 4 indicate that, when the drag driving device of the driving device test tool is a motor with an output power greater than the output power of the measured driving device, the driving device test tool only needs to adjust the connection or separation of the second coupling 80 and the drag support plate 30 to switch between the two locked-rotor test modes.

[0082] The driving device test tool provided by the embodiments of the present application can realize locked-rotor testing, counter driving force testing, and switching thereof for the measured driving device, without separately providing a locked-rotor test tool or a counter driving force test tool, i.e., providing a tool that can be in different test modes to test multiple performance parameters of the measured driving device, thereby reducing the use cost.

[0083] Specifically, the specific structure of the base 10 is not limited here, and the base 10 can be a substrate.

[0084] Optionally, a first reinforcing plate can be arranged to connect the measured driving device support plate 20 and the base 10, and a second reinforcing plate can be arranged to connect the drag support plate 30 and the base 10, and the number of the first reinforcing plate and the second reinforcing plate can be at least one, so that the first reinforcing plate can enhance the connection strength between the measured driving device support plate 20 and the base 10, and the second reinforcing plate can enhance the connection strength between the drag support plate 30 and the base 10.

[0085] As an optional embodiment, referring to Figure 1 and Figure 2 , the driving device test tool further comprises a first coupling 70, and the output end of the measured driving device 60 is connected to the detection sensor 50 through the first coupling 70.

[0086] Optionally, the first coupling 70 and the second coupling 80 can be connected to opposite ends of the detection sensor 50, respectively.

[0087] In addition, optionally, the first coupling 70 and the second coupling 80 can both be tubular couplings, i.e., the cross-sectional shape of the first coupling 70 and the second coupling 80 can both be circular rings, and the diameter of the first coupling 70 can match the diameter of the output end of the measured driving device 60, so that the first coupling 70 can be connected to the output end of the measured driving device 60.

[0088] The output end of the measured driving device 60 is connected with the detection sensor 50 through the first coupling 70, so that the connection strength and stability between the detection sensor 50 and the output end of the measured driving device 60 are enhanced.

[0089] As an optional embodiment, the first limiting piece is arranged on the first coupling 70, and the second limiting piece is arranged on the output end of the measured driving device 60, and the first limiting piece and the second limiting piece are connected in cooperation.

[0090] In the embodiment, the first limiting piece is arranged on the first coupling 70, and the second limiting piece is arranged on the output end of the measured driving device 60, so that the connection stability between the first coupling 70 and the output end of the measured driving device 60 is further enhanced.

[0091] As an optional embodiment, the third limiting piece is arranged on the second coupling 80, and the fourth limiting piece is arranged on the towing support plate 30, and the third limiting piece and the fourth limiting piece are connected in cooperation.

[0092] In the embodiment, the third limiting piece is arranged on the second coupling 80, and the fourth limiting piece is arranged on the towing support plate 30, so that the connection stability between the second coupling 80 and the towing support plate 30 is further enhanced.

[0093] It should be noted that, optionally, the output end of the measured driving device 60 can be arranged in the first coupling 70, the first limiting piece can be arranged on the inner wall of the first coupling 70, and the second limiting piece can be arranged on the output end of the measured driving device 60 and faces the first limiting piece; optionally, the second coupling 80 can be arranged in the through hole of the towing support plate 30, and the third limiting piece can be arranged on the outer wall of the second coupling 80, and the fourth limiting piece can be arranged on the inner wall of the through hole and faces the third limiting piece.

[0094] It should be noted that the specific structure of the first limiting piece, the second limiting piece, the third limiting piece and the fourth limiting piece is not limited here.

[0095] As an optional embodiment, one of the first limiting piece and the second limiting piece is a protrusion, and the other is a groove; and / or,

[0096] One of the third limiting piece and the fourth limiting piece is a protrusion, and the other is a groove.

[0098] In the embodiment, one of the first limiting member and the second limiting member is a protrusion, and the other is a groove, one of the third limiting member and the fourth limiting member is a protrusion, and the other is a groove, so that the cooperation of the protrusion and the groove can make the structure of the limiting member simpler and the limiting effect better.

[0100] Optionally, the second coupling 80 can be an integral molding structure with the fixing member 81, so that the connection strength between the second coupling 80 and the fixing member 81 can be enhanced.

[0101] Referring to Figure 4 , when the fixing member 81 is connected with the pair of towing support plates 30, the measured driving device 60 is in the locked-rotor state; referring to Figure 1 and Figure 3 , when the fixing member 81 is separated from the pair of towing support plates 30, the measured driving device 60 is in the counter-driven state or the locked-rotor state, as shown in the schemes of the serial numbers 3 and 4 in Table 1.

[0102] It should be noted that the specific type of the fixing member 81 is not limited here, and optionally, the fixing member 81 can be a fixed flange or a fixed connecting plate.

[0103] In the embodiment, the second coupling 80 realizes the switching of the connection and separation with the pair of towing support plates 30 through the fixing member 81, so that the convenience degree of the connection and separation switching of the second coupling 80 and the pair of towing support plates 30 can be improved, to realize the convenient switching of the test mode.

[0104] As an optional embodiment, referring to Figure 5 , the fixing member 81 is provided with a threaded hole 811, and the threaded hole 811 is used for cooperation and disassembly with a first fixed bolt to realize the connection or separation of the fixing member 81 and the pair of towing support plates 30.

[0105] As an optional embodiment, referring to Figure 5 , the fixing member 81 is provided with a through hole 812, the through hole 812 is used for avoiding the fasteners of the pair of towing support plates 30 and the pair of towing driving devices 40, i.e., a second fixed bolt, and the second fixed bolt is a fastener used for fixing the pair of towing support plates 30 and the pair of towing driving devices 40.

[0106] The shape of the cross section of the through hole 812 is not limited here. Optionally, the cross section of the through hole 812 can be circular, rectangular, or oval, etc.

[0107] In the embodiment, the second fixing bolt for fixing and connecting the towing support plate 30 and the towing driving device 40 can be arranged in the through hole 812, that is, the through hole 812 can accommodate the second fixing bolt. Compared with the case where no through hole is arranged on the fixing member 81 and the second fixing bolt directly abuts against the surface of the fixing member 81, the embodiment can avoid the phenomenon that the second fixing bolt is blocked between the fixing member 81 and the towing support plate 30, so that the fixing member 81 and the towing support plate 30 cannot abut against each other, thereby affecting the connection effect of the fixing member 81 and the towing support plate 30.

[0108] As an optional embodiment, as shown in Figure 6 , the measured driving device support plate 20 is provided with a receiving groove with a size suitable for the size of the measured driving device 60, for accommodating and stabilizing the measured driving device 60. Figure 6 As an optional embodiment, as shown in , the measured driving device support plate 20 is provided with a receiving groove with a size suitable for the size of the measured driving device 60, for accommodating and stabilizing the measured driving device 60.

[0109] For example, as an optional embodiment, the measured driving device support plate 20 is provided with a first receiving groove 21 for accommodating the measured driving device 60. In this way, the first receiving groove 21 can enhance the accommodation and fixing effect of the measured driving device 60.

[0110] It should be noted that the current driving device test tool can usually only test one size of measured driving device 60. When another size of measured driving device needs to be tested, the support plate needs to be replaced, because the position of the receiving groove for accommodating the measured driving device and the threaded hole for fixing the measured driving device arranged on the original support plate are not suitable for the new size of measured driving device, thereby limiting the use scene of the driving device test tool.

[0111] As an optional embodiment, as shown in Figure 6 , the number of the first receiving grooves 21 is multiple, and the multiple first receiving grooves 21 are arranged in a stepped manner. The first receiving grooves 21 can be used to accommodate measured driving devices 60 of different sizes, so that the measured driving devices 60 of different sizes can be accommodated without replacing the measured driving device support plate 20.

[0112] Optionally, the radial dimensions of the first accommodating grooves 21 can be different (e.g., different diameters), so as to form the aforementioned stepped distribution, and thus the first accommodating grooves 21 of different sizes can accommodate the corresponding sizes of the measured driving devices 60, so that the driving device test tool in the embodiment of the present application can be used for testing different sizes of the measured driving devices 60, the use scenarios of the driving device test tool in the embodiment of the present application are expanded, and the thickness of the entire measured driving device support plate 20 can be reduced.

[0113] As an optional embodiment, as shown in Figure 7 , the drag support plate 30 is provided with a second accommodating groove 31 for accommodating and stabilizing the drag driving device 40, and the size of the second accommodating groove 31 can be matched with the size of the drag driving device 40.

[0114] Similarly, the driving device test tool in the aforementioned embodiment can generally only be provided with one size of the drag driving device 40, and when another size of the drag driving device needs to be replaced (for example, the output power of the drag support device is greater than the output power of the measured driving device, so as to realize the scheme described in Table 1 No. 4), the drag support plate 30 needs to be replaced, because the original drag support plate 30 is only provided with one second accommodating groove 31 for accommodating the drag driving device 40, and the thread hole position for fixing the drag driving device on the second accommodating groove 31 is not suitable for the new size of the measured driving device, so that the use scenarios of the driving device test tool are limited.

[0115] To solve the above problems, an embodiment of the present application is provided, as shown in Figure 7 and Figure 8 , the drag support plate 30 is provided with a plurality of second accommodating grooves 31, that is, the number of the second accommodating grooves 31 is multiple, the plurality of second accommodating grooves 31 are arranged in a stepped distribution, and the plurality of second accommodating grooves 31 are used for accommodating different sizes of the drag driving device 40.

[0116] Among them, the radial dimensions of any two of the plurality of second accommodating grooves 31 are different (e.g., different diameters), so as to form the aforementioned stepped distribution, so that the second accommodating grooves 31 of different sizes can accommodate the corresponding sizes of the drag driving device 40.

[0117] In the embodiment of the present application, since the second accommodating grooves 31 are used for accommodating the drag driving device 40, and the drag support plate 30 is provided with a plurality of second accommodating grooves 31, that is, the plurality of second accommodating grooves 31 can be used for accommodating different sizes of the drag driving device 40, and the corresponding size of the drag driving device 40 can be selected according to the size of the measured driving device 60, so as to further enhance the testing accuracy of the measured driving device 60, further expand the use scenarios of the driving device test tool, and reduce the thickness of the entire drag support plate 30.

[0118] As an optional implementation, the counter support plate 30 is detachably connected with the base 10 and the first support 32 respectively, and the first support 32 is in sliding connection with the base 10; and / or,

Meanwhile, the measured driving device support plate 20 is detachably connected with the base 10 and the second support 22 respectively, so that the measured driving device support plate 20, the base 10 and the second support 22 can be conveniently disassembled and assembled.

[0122] It should be noted that when the measured driving device 60 needs to be tested for locked-rotor, the first support 32 can be controlled to be separated from the counter support plate 30, and to slide relative to the base 10 and towards a direction away from the counter support plate 30, and then a counter support plate 30 specially used for locked-rotor test can be replaced.

[0123] In addition, when the size of the first accommodating groove 21 on the measured driving device support plate 20 does not match the size of the measured driving device 60, the measured driving device support plate 20 can also be controlled to be separated from the second support 22, and then the second support 22 can be controlled to slide relative to the base 10 and towards a direction away from the measured driving device support plate 20, and finally a measured driving device support plate 20 having a first accommodating groove 21 with a size matching that of the measured driving device 60 can be replaced.

[0124] As an optional implementation, referring to Figure 9 The first support 32 is connected with the base 10 through a first connecting plate 90, and the first support 32 is connected with the counter support plate 30, and the first connecting plate 90 is provided with at least one first connecting hole 91 for fixed connection with the base 10; and / or,

[0126] The base 10 can be provided with a plurality of fixed connection holes 11 which can be connected with the first connection hole 91 and the second connection hole 93. The fixed connecting members can be respectively arranged in the first connection hole 91 and the corresponding fixed connection hole 11, so as to realize the connection between the first support 32 and the base 10. Similarly, the fixed connecting members can be respectively arranged in the second connection hole 93 and the corresponding fixed connection hole 11, so as to realize the connection between the second support 22 and the base 10.

[0127] In the embodiment, the assembly or disassembly between the first support 32 and the base 10 is convenient, and the assembly or disassembly between the second support 22 and the base 10 is also convenient.

[0128] As an optional embodiment, the number of the measured driving device support plates 20 is multiple, and the multiple measured driving device support plates 20 can move relative to the detection sensor 50.

[0129] In the embodiment, the number of the measured driving device support plates 20 is multiple, and each measured driving device support plate 20 can be connected with multiple measured driving devices 60 of different sizes. Thus, the number of the measured driving devices 60 that can be tested is further increased, and the size range of the measured driving devices 60 that can be tested is expanded, that is, the use scene of the driving device test tool in the embodiment is further expanded.

[0131] In the embodiment, the multiple measured driving device support plates 20 are arranged in the sliding groove 101 and can slide along the sliding groove 101. Thus, the positions of the multiple measured driving device support plates 20 can be conveniently adjusted, and the measured driving device support plates 20 and the corresponding measured driving devices 60 on the measured driving device support plates 20 participating in the test can be flexibly selected, which is beneficial to the automatic stall and / or back-drive detection of the measured driving devices on the production line in the automatic batch production.

[0133] In the embodiments of the present application, the disc pulley device 110 is rotated to drive the plurality of measured driving device support plates 20, and then the measured driving device support plates 20 and the corresponding measured driving devices 60 on the measured driving device support plates 20 participating in the test can be flexibly selected. This is also beneficial for automatic batch production, and the measured driving devices can be automatically tested for locked-rotor and / or back-drive on the production line. Moreover, this is more convenient for use in a factory with limited space, because the larger the length of the scheme occupies, Figure 10 the larger the length of the scheme occupies.
