[0023] The specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-Figure 6As shown, the utility model proposes a rotating shaft torque detection device, which is used to dock with the rotating shaft 101 of the product 100 to detect the torque of the product 100. The rotating shaft torque detection device includes a first mounting platform 300, a second mounting platform 500, a floating member 900, a detection mechanism 1100 and a second driving member 800 installed on the second mounting platform 500. The first side of the first mounting platform 300 is used to mount the product 100, and the second mounting platform 500 is installed on the second side of the first mounting platform 300. The detection mechanism 1100 can be movably mounted on the second mounting platform 500 and connected to the rotating shaft 101 through the floating member 900. The second driving member 800 is drivingly connected to the detection mechanism 1100 to drive the detection mechanism 1100 to approach the first mounting platform 300, thereby connecting the floating member 900 with the rotating shaft 101 to detect the torque of the rotating shaft 101.

[0025] The shaft torque detection device further includes a first plate 200 and a connecting rod 10001. The first plate 200 is connected between a first mounting platform 300 and a second mounting platform 500. The first mounting platform 300 is provided with a fixing member 400 and a first hole 301. The product 100 is fixedly connected to the first mounting platform 300 through the fixing member 400, and the shaft 101 extends from the first hole 301.

[0026] The detection mechanism 1100 includes a movable plate 600, a first driving member 700 and a torque sensor 701. The movable plate 600 can be slidably mounted on the second mounting platform 500. The first driving member 700 is mounted on the movable plate 600. The output end of the first driving member 700 is connected to the torque sensor 701. A second hole 201 is provided on the first plate 200. The first end of the connecting rod 10001 is fixedly connected to the torque sensor 701. The second end of the connecting rod 10001 passes through the second hole 201 and is fixedly connected to the floating member 900.

[0027] A slot 102 is provided at the end of the rotating shaft 101, and the floating member 900 includes a protrusion 905 that cooperates with the slot 102 and is engaged with the floating member 900. Driven by the second driving member 800, the movable plate 600 approaches the first plate 200 to drive the floating member 900 to approach the end of the rotating shaft 101 until the protrusion 905 is engaged with the slot 102.

[0028] Specifically, based on the above embodiments, the specific implementation methods are as follows:

[0029] First, the product 100 is installed on the first mounting platform 300 through the fixing member 400. It should be noted that the shaft 101 of the product 100 should be able to pass through the first hole 301. Since the floating member 900 is deviated from the shaft 101 in the default state, in order to achieve the connection between the floating member 900 and the shaft 101, the movable plate 600 is driven by the second driving member 800 to continuously approach the first plate 200, which drives the floating member 900 to approach until the protrusion 905 thereon is connected with the slot 102 of the shaft 101. It should be emphasized here that the protrusion 905 on the floating member 900 and the slot 102 of the shaft 101 are not necessarily in a state where they can be connected by lifting at the beginning, so a variety of processing embodiments can be adopted; Processing embodiment one: the first driving member 700 is also required to be driven. During the docking, the driving rotation speed of the first driving member 700 is slow, so that The floating member 900 is obtained that while rotating, it is constantly approaching the rotating shaft 101. Under such operation, the protrusion 905 can gradually approach and engage in the card slot 102; processing embodiment 2: an additional image sensor is provided, which is used to identify the positional relationship between the protrusion 905 and the card slot 102, and the deflection angle of the first driving member 700 before docking is controlled according to the positional relationship. After completing the deflection of the floating member 900, the floating member 900 is driven to approach the rotating shaft 101 through the second driving member 800 to complete the engagement of the protrusion 905 with the card slot 102; after completing the docking work, the first driving member 700 can start to execute the preset rotation rate to perform torque detection on the rotating shaft 101 of the product 100, and continuously obtain data through the torque sensor 701 to effectively improve the data accuracy. In this embodiment, the first driving member 700 adopts a servo motor and the second driving member 800 adopts a telescopic cylinder.

[0030] Furthermore, the floating member 900 includes a flange 901, an elastic member 902 and a sleeve 903. The first end of the sleeve 903 is provided with an inner hole 904. The second end of the sleeve 903 is fixedly connected to the protrusion 905. The first end of the sleeve 903 is fixedly connected to the second end of the connecting rod 10001 through the flange 901, and the elastic member 902 is installed in the inner hole 904.

[0031] Specifically, the floating member 900 has a certain buffer design. Therefore, when the protrusion 905 is docked with the slot 102, if the moving stroke provided by the second driving member 800 is too large, then after the end of the sleeve 903 hits the rotating shaft 101, the elastic member 902 inside it will compensate for the excess stroke to avoid accidents and improve a certain fault tolerance rate.

[0032] Furthermore, in the present embodiment, the shaft torque detection device is applied to an automated detection line. When feeding the product 100, the feeding is controlled by a robot. Therefore, the product 100 needs to be stable and quickly disassembled when installed on the first mounting table 300. Therefore, the fixing member 400 includes a mounting seat 401 and a plurality of fasteners 402. The plurality of fasteners 402 are fixed on the first mounting table 300. The mounting seat 401 is fixed on the first mounting table 300 through the plurality of fasteners 402. The mounting seat 401 is provided with a plurality of positioning pins 4011. The product 100 is provided with a plurality of positioning holes 103 respectively engaged with the plurality of positioning pins 4011.

[0033] Furthermore, the second mounting platform 500 includes a second plate 501 and a plurality of guide rods 502 fixedly connected to the second side of the first plate 200. The second plate 501 is fixedly connected to the ends of the plurality of guide rods 502 respectively. The movable plate 600 is provided with a plurality of sleeves 601 respectively sleeved on the plurality of guide rods 502.

[0034] Furthermore, the shaft torque detection device also includes a first buffer 10002 and a second buffer 10003. The first buffer 10002 is installed on the first plate 200 and faces the movable plate 600. The second buffer 10003 is installed on the movable plate 600 and faces the second plate 501. The setting of the first buffer 10002 and the second buffer 10003 further ensures that the driving of the second driving member 800 can be within a safe and controllable range.

[0035] The above is a shaft torque detection device or multiple implementations provided in combination with specific content, and it is not considered that the specific implementation of the utility model is limited to these descriptions. Any method, structure, etc. similar to or identical to the method, structure, etc. of the utility model, or a number of technical deductions or replacements based on the concept of the utility model, should be regarded as the protection scope of the utility model.
