[0022] Example:

[0023] As attached Figure 1 To Attachment Figure 4 As shown:

[0024] The utility model provides a gearbox torque test platform, comprising a mounting platform 1 and a testing platform 2, wherein the mounting platform 1 and the testing platform 2 are integrally formed, a torque sensor 3 is arranged on the testing platform 2, one end of the torque sensor 3 is connected to a measuring load 4, the model of the torque sensor 3 is LZ DN2, and the other end of the torque sensor 3 is connected to a gearbox shaft to be tested, and the torque of the gearbox can be detected by driving the gearbox to rotate through an external motor;

[0025] A swivel 5 is rotatably connected to the mounting table 1, and multiple groups of shaft supports are distributed circumferentially on the swivel 5. In the present embodiment, there are three groups of shaft supports, which include mounting seats 7 and bearing seats 6 symmetrically arranged on both sides of the swivel 5. The mounting seats 7 and bearing seats 6 of different shaft supports have different sizes. Each group of shaft supports corresponds to a transmission of a different type. A top cover is hinged on the top of the mounting seat 7, and the top cover is buckled on the mounting seat 7 to form a bearing hole. The top cover and the mounting seat 7 are detachably connected. After the swivel 5 is rotated to the corresponding type of shaft support, one end of the transmission passes through the bearing seat 6, and the other end is placed in the mounting seat 7. The top cover is then covered and fixed by bolts, and the transmission can be tested. The external motor is connected to the front end shaft of the transmission, and a spline groove sleeve 14 is penetrated on the bearing seat 6. The rear end of the transmission is inserted into the spline groove sleeve 14. The spline groove sleeve 14 is connected to the torque sensor 3 through the coupling 11, and the detection operation can be performed.

[0026] The movable groove 12 is provided on the mounting platform 1, and a pin handle 10 is inserted into the movable groove 12. A plurality of positioning mechanisms are provided at the bottom of the mounting platform 1 to temporarily fix the position of the swivel 5. The positioning mechanism includes a telescopic groove 103 provided at the bottom of the swivel 5, and a positioning buckle 101 is slidably provided in the telescopic groove 103. The positioning buckle 101 passes through the telescopic groove 103 and extends into the movable groove 12. The positioning buckle 101 and the telescopic groove 103 are connected by a spring 102. The pin handle 10 is inclined near the top of the end face of the positioning buckle 101. Each group of positioning mechanisms matches the position of each group of load shaft supports. When the swivel 5 rotates to one of the groups of load shaft supports, When the torque sensor 3 is positioned, the positioning buckle 101 of one of the positioning mechanisms is just located above the movable groove 12. At this time, the spring drives the positioning buckle 101 to pop out, and the positioning buckle 101 is stuck in the movable groove 12 so that the swivel 5 no longer rotates. The width of the movable groove 12 is adapted to the diameter of the swivel 5. When the rotation position of the swivel 5 needs to be changed again, the pin handle 10 is pushed, and the inclined surface at the end of the pin handle 10 pushes the positioning buckle 101 and lifts up the positioning buckle 101, so that the positioning buckle 101 retracts into the telescopic groove 103, and the swivel 5 is no longer restricted and can resume rotation; the positioning of the swivel 5 increases the stability during transmission detection.

[0027] Among them, a through cavity located in the middle of the swivel 5 is opened on the mounting platform 1, and a supporting inner platform 9 is slidably arranged in the through cavity. A supporting frame 13 is arranged at the bottom of the mounting platform 1, and an oil cylinder 8 is arranged between the supporting inner platform 9 and the supporting frame 13. The supporting inner platform 9 can be driven to rise and fall by the oil cylinder 8, which can play a role of temporary support in the process of placing the transmission. When the transmission is installed on the corresponding load-bearing shaft support, the supporting inner platform 9 can be lowered.
