[0025] Example 1 refer to Figure 1 The present invention provides a fully automatic detection system for a manual transmission, including a transmission transport unit 100, a transmission clamping unit 200, a transmission power input unit 300, a transmission output detection unit 400 and a detection control unit 500. Preferably, it also includes a base 800. The detection control unit 500 can be optionally connected to the base 800 through a detection control support frame 501.

[0026] Among them, the transmission clamping unit 200, the transmission power input unit 300, the transmission output detection unit 400 and the detection control unit 500 are all arranged on the base 800. The head end of the transmission transport unit 100 is used to place the transmission body 900 to be inspected, and the tail end of the transmission transport unit 100 extends to the base 800. The transmission transport unit 100 is used to transport the transmission body 900 to a designated position to facilitate automatic operation of the transmission body 900. The designated position is the clamping position.

[0027] When the transmission body 900 is in the detection position, the transmission clamping unit 200 automatically lifts the transmission body 900 to the specified position to facilitate clamping the transmission body 900. The specified position is the detection position, which facilitates the transmission power input unit 300 and the transmission output detection unit 400 to be respectively connected to the input and output ends of the transmission body 900.

[0028] The transmission clamping unit 200 is located between the transmission power input unit 300 and the transmission output detection unit 400. The transmission clamping unit 200, the transmission power input unit 300 and the transmission output detection unit 400 are all communicated with the detection control unit 500. A proximity sensor can be optionally set next to the clamping position to determine whether the transmission transport unit 100 transports the transmission body 900 to the clamping position; the proximity sensor is communicated with the transmission transport unit 100 and the detection control unit 500 respectively. When the transmission body 900 is transported to the clamping position, the transmission transport unit 100 stops to facilitate the transmission clamping unit 200 to clamp the transmission body 900; at the same time, the detection control unit 500 starts to control the transmission clamping unit 200, the transmission power input unit 300 and the transmission output detection unit 400 to detect the transmission body 900.

[0029] The transmission power input unit 300 is used to simulate the engine to provide the set power to the transmission body 900, so the detection control unit 500 sets the input parameters, such as the speed, to the transmission power input unit 300 according to demand; the transmission output detection unit 400 is used to simulate vehicle driving, and the detection control unit 500 sets the resistance torque to the transmission output detection unit 400 according to demand. The transmission output detection unit 400 is connected to the output end of the transmission body 900 to obtain the output torque result of the transmission body 900 and send it to the detection control unit 500.

[0030] The transmission power input unit 300 and the transmission output detection unit 400 are both slidably connected to the base 800. When the transmission body 900 is in the detection position, the transmission power input unit 300 and the transmission output detection unit 400 slide close to the transmission body 900 and are connected to the corresponding input and output ends of the transmission body 900.

[0032] For further explanation, see Figures 2 to 4The transmission clamping unit 200 includes a lifting mechanism 210 , a clamping mechanism 220 , a moving mechanism 230 and a clamping support plate 240 . The lifting mechanism 210 , the clamping mechanism 220 and the moving mechanism 230 are all in communication connection with the detection control unit 500 .

[0033] The lifting mechanism 210 is located directly below the clamping position, which is convenient for raising the height of the transmission body 900 when the transmission body 900 reaches the clamping position, so that the transmission body 900 is coaxially arranged with the transmission power input unit 300 or the transmission output detection unit 400. The output end of the moving mechanism 230 is connected to the fixed end of the lifting mechanism 210, and the moving mechanism 230 is used to drive the lifting mechanism 210 to move to the detection position for easy clamping and fixation; the clamping support plate 240 is located between the transmission power input unit 300 and the detection position, and the clamping mechanism 220 is arranged on the clamping support plate 240. The transmission body 900 at the detection position is connected to the clamping support plate 240 through the clamping mechanism 220, which is convenient for connection with the transmission power input unit 300 and the transmission output detection unit 400 respectively.

[0034] Specifically, refer to Figure 2 The lifting mechanism 210 includes a lifting drive 211 and a lifting plate 212, and the moving mechanism 230 includes a moving fixed plate 231, a moving connecting plate 232, a moving drive 233 and a moving guide rail 234. The lifting drive 211 and the moving drive 233 are both communicatively connected to the detection control unit 500.

[0035] The movable fixed plate 231 is connected to the base 800, the movable guide rail 234 is arranged on the upper end surface of the movable fixed plate 231, the movable connecting plate 232 is arranged above the movable fixed plate 231 and is slidably connected to the movable fixed plate 231 through the movable guide rail 234, the fixed end of the movable drive 233 is connected to the movable fixed plate 231, the output end of the movable drive 233 is connected to the movable connecting plate 232, the jacking plate 212 is arranged above the movable connecting plate 232, the fixed end of the jacking drive 211 is located below the movable fixed plate 231, the output end of the jacking drive 211 passes through the movable fixed plate 231 and the movable connecting plate 232 and is connected to the lower end surface of the jacking plate 212, the movable connecting plate 232 is connected to the movable connecting plate 232, so that the jacking drive 211 can lift the transmission body 900 through the jacking plate 212, and then the movable drive 233 drives the jacking mechanism 210 to move horizontally through the movable connecting plate 232, driving the transmission body 900 to move to the detection position.

[0036] refer to Figure 3The clamping mechanism 220 includes a plurality of clamping components, a guide hole 241 is opened on the clamping support plate 240, and the plurality of clamping components are arranged in a circular array around the axis of the guide hole 241, and the guide hole 241 is coaxially arranged with the output end of the transmission power input unit 300; so that after the transmission body 900 is reliably connected to the clamping support plate 240 through the clamping mechanism 220, it is ensured that the output end of the transmission power input unit 300 can pass through the guide hole 241 and be reliably and accurately transmitted to the input end of the transmission body 900.

[0037] Preferably, a plurality of positioning pins can be provided on the peripheral side of the guide hole 241, so that when the moving mechanism 230 drives the transmission body 900 to move to the detection position, its own preset positioning holes and the positioning pins can be docked, thereby achieving more precise positioning and installation, and ensuring that the automatic test is more accurate and reliable.

[0038] refer to Figure 4 The clamping assembly includes a clamping positioning block 221, a radial adjustment drive 222, a clamping limit plate 223, a clamping telescopic drive, a clamping block 224, a screw 225 and a telescopic drive housing 226. The radial adjustment drive 222 and the clamping telescopic drive are both communicated with the detection control unit 500; the clamping telescopic drive is arranged in the telescopic drive housing 226, and the output end of the clamping telescopic drive is connected to the clamping block 224 through the screw 225, and the screw 225 is threadedly connected to the telescopic drive housing 226, wherein the clamping telescopic drive is connected to the end of the screw 225 through a bearing, so that when the telescopic drive housing 226 drives the screw 225 to extend and retract, the screw 225 can rotate relative to the telescopic drive housing 226, thereby limiting and clamping the end of the transmission body 900 from multiple directions.

[0039] The fixed end of the radial adjustment drive 222 and the clamping positioning block 221 are both connected to the end face of the clamping support plate 240, and the telescopic drive housing 226 is slidably connected to the clamping positioning block 221 along the radial direction of the guide hole 241, and can adjust the straight-line distance between the clamping assembly and the center of the guide hole 241 according to the transmission body 900 of different specifications and sizes, and has stronger adaptability; the output end of the radial adjustment drive 222 is connected to the telescopic drive housing 226 through the clamping limit plate 223, and the number of clamping positioning blocks 221 is preferably two, and the two clamping positioning blocks 221 are arranged on opposite sides of the telescopic drive housing 226, and the clamping limit plate 223 is sleeved on the outside of any clamping positioning block 221 to make the sliding more stable.

[0040] Further preferably, the clamping assembly also includes a limiting component 227, which is a U-shaped structure. The back of the limiting component 227 is connected to the end face of the clamping support plate 240, and the opening of the limiting component 227 is opposite to the clamping limiting plate 223. The clamping limiting plate 223 moves back and forth inside the opening of the limiting component 227 for limiting.

[0041] Further qualification, see Figure 2 and Figure 5 The transmission transport unit 100 includes a conveying line 110 and a transmission support mechanism 120 for supporting the transmission body 900. The transmission support mechanism 120 cooperates with the conveying line 110. The conveying line 110 is used to drive the transmission body 900 to move to the clamping position through the transmission support mechanism 120. The jacking mechanism 210 and the clamping mechanism 220 lift the transmission body 900 to the detection position through the transmission support mechanism 120; the conveying line 110 is communicated with the detection control unit 500, so that the conveying line 110 stops when the transmission body 900 moves to the clamping position.

[0042] Preferably, in order to avoid the conveying line 110 from stopping and not conveying beyond the clamping position in time, the transmission conveying unit 100 also includes a first blocker 130. The first blocker 130 is arranged at the end of the conveying line 110. The first blocker 130 is located at the side end of the clamping position and is used to limit the movement of the transmission support mechanism 120 on the conveying line 110 to ensure safe use.

[0043] refer to Figure 5 and Figure 6 The transmission support mechanism 120 includes a support plate 121, a positioning column 122 and a sliding support block 123. The positioning column 122 and the sliding support block 123 are both arranged on the upper end surface of the support plate 121. The positioning column 122 is used to achieve precise positioning of the support plate 121 and the transmission body 900, and the sliding support block 123 is used to auxiliary support the transmission body 900 to ensure that the transmission body 900 and the support plate 121 are stably and reliably connected; preferably, an adjustment guide rail 124 is provided on the support plate 121, and the adjustment guide rail 124 is provided along the axial direction of the transmission body 900, so that the sliding support block 123 and the support plate 121 are slidably connected along the length direction of the transmission body 900, and can be adjusted according to the length of the transmission body 900, thereby ensuring safe and reliable support and increasing the scope of application.

[0044] refer to Figure 2 When in use, the top of the lifting plate 212 contacts the bottom of the support plate 121, and is used to lift and move the transmission body 900 through the support plate 121. In order to ensure that the connection between the lifting plate 212 and the support plate 121 is stable and reliable, it is preferably provided with a pallet positioning pin 213 at the top of the lifting plate 212 and a pallet positioning block at the bottom of the support plate 121, so that when the support plate 121 moves to the clamping position, the pallet positioning pin 213 and the pallet positioning block are engaged when the lifting plate 212 is raised, thereby improving the connection reliability between the lifting plate 212 and the support plate 121.

[0045] Since multiple transmission bodies 900 are usually placed on the conveying line 110, in order to avoid collisions between the transmission bodies 900 during the conveying process, it is preferred that multiple second blockers 131 are provided at the side ends of the support plate 121, and the multiple second blockers 131 are arranged in an array along the circumference of the support plate 121; since the distance between the positioning hole close to the input end of the transmission body 900 and the support plate 121 is fixed, the length of the output end of different transmission bodies 900 extending to the outside of the support plate 121 is different. Therefore, in order to avoid collisions, the second blockers 131 at the corresponding side ends of the support plate 121 can be connected through an extension rod 132 to meet actual operational requirements.

[0046] Further qualification, see Figure 6 In order to avoid manual on-site connection of relevant lines or oil pipes to the transmission body 900 at the clamping position or detection position, the transmission support mechanism 120 preferably also includes a wire harness docking female port 125, which is arranged on the support plate 121. The input end of the wire harness docking female port 125 is connected to the transmission body 900. Therefore, in the first section of the conveying line 110, when the transmission body 900 is placed on the support plate 121, the operator can first connect the wire harness docking female port 125 to the transmission body 900.

[0047] Corresponding, reference Figure 1 and Figure 7 The transmission clamping unit 200 also includes a harness docking mechanism 250, which includes a harness docking male port 251 and a harness docking drive 252; the harness docking drive 252 is arranged on the outside of the conveying line 110, and the harness docking drive 252 is located on one side of the detection position. The fixed end of the harness docking drive 252 is connected to the base 800, and the output end of the harness docking drive 252 is connected to the harness docking male port 251 through the harness support block 253. The input end of the harness docking male port 251 cooperates with the harness docking female port 125 of the detection position, so that when the support plate 121 moves to the clamping position, the harness docking drive 252 pushes the harness docking male port 251 to connect with the harness docking female port 125 on the clamping position support plate 121, thereby realizing automatic wiring.

[0048] It is further explained that since the detection methods and input data of transmission bodies 900 of different specifications are different, the detection control unit 500 needs to determine the input data according to the specifications of the transmission body 900; in order to reduce manual input, it is preferred to set an RFID identification module at the clamping position, and correspondingly set an RFID tag at the bottom of the support plate 121, and the RFID identification module obtains the product information of the transmission body 900 at the clamping position by identifying the RFID tag; the RFID identification module is communicated with the detection control unit 500, and the RFID identification module uploads the identified product information to the detection control unit 500, so that the detection control unit 500 can complete the detection of the transmission body 900 more efficiently and accurately and rotate the detection results.

The ratio of the rotational speed of the input end in the input parameters to the rotational speed of different gears can be used to determine whether there is a fault in the gear shifting of the transmission body 900; therefore, the detection control unit 500 is used to obtain the detection results of the transmission body 900 based on the input parameters, rotation detection results, gear shift stroke operation data, gear shift operation detection data and gear shift vibration detection data, so that the detection of the transmission body 900 is more comprehensive and sufficient to meet actual detection needs.

By simulating manual gear shifting operations through the multi-degree-of-freedom robotic arm 610, it is possible to know whether the gear shifting strokes corresponding to different gears meet the requirements through the gear shifting stroke operation data. At the same time, the three-dimensional force sensor 630 can be used to obtain whether there is any abnormality in the force during the gear shifting operation, which is convenient for judging whether there is a blockage or jamming fault in the gear shifting, and obtaining the gear shifting operation detection data.
