[0028] like Figure 1 and Figure 2 As shown, the hydraulic wrench torque test platform of the present invention comprises a platform 2, a first positioning member 4, an intelligent sleeve 6, a block 7 and a positioning adjustment mechanism. A positioning adjustment mechanism is provided between the first positioning member 4 and the platform 2. The positioning adjustment mechanism is used to adjust the relative position of the first positioning member 4 on the platform 2 and to install the first positioning member 4 on the platform 2. The intelligent sleeve 6 is suitable for being sleeved on the first positioning member 4. When the intelligent sleeve 6 is sleeved on the first positioning member 4, a connecting hole for installing a driving head of a hydraulic wrench is formed at one end of the intelligent sleeve 6 away from the platform 2. The block 7 is formed with a block side 8 for abutting against a reaction arm of the hydraulic wrench. In some specific embodiments, the connecting hole is a square hole. The hydraulic wrench torque test platform of the present invention When the test platform performs torque tests on hydraulic wrenches of different specifications and models, the smart sleeve 6 is sleeved on the first positioning member 4, and the driving head of the hydraulic wrench is installed in the square hole of the smart sleeve 6. The relative positions of the first positioning member 4 and the side 8 of the block are adjusted by the positioning adjustment mechanism so that the reaction arm of the hydraulic wrench is against the middle position of the side 8 of the block, and then the first positioning member 4 is fixed to the platform 2 by the positioning adjustment mechanism. Therefore, for hydraulic wrenches of different specifications and models, the hydraulic wrench torque test platform of the present invention can ensure that the reaction arm is relatively close to the side 8 of the block, has good adaptability, and the positioning process is relatively simple. It also avoids line contact between the reaction arm and the side 8 of the block, and the testing process is safer.

[0029] As a specific implementation method, Figure 2As shown, the positioning and adjustment mechanism includes a fixing member 5 and a sliding hole 3 formed on the platform 2, the first positioning member 4 is slidably arranged in the sliding hole 3, and the fixing member 5 is used to fix the first positioning member 4 on the platform 2. As a further specific implementation method, the first positioning member is a nut, the fixing member 5 is a bolt, and the sliding hole 3 is a waist-shaped hole. The positioning and adjustment mechanism also includes an elastic washer and a flat washer. The bolt is slidably arranged in the sliding hole 3, the rod of the bolt passes through the sliding hole 3, the flat washer and the elastic washer, and one end of the rod passing through the sliding hole 3 is threadedly connected to the nut. When the nut and the bolt are tightened, the first positioning member 4, the elastic washer and the flat washer are fixed on the platform 2. When the nut and the bolt are loosened, the first positioning member 4 can slide along the waist-shaped hole to change the relative position of the first positioning member 4 and the side surface 8 of the block. In this embodiment, the block 7 is a square block, and the waist-shaped hole is arranged along the diagonal direction of the square block. One first positioning member 4 corresponds to a block side 8 on the left and right. The block side 8 of this embodiment is a plane. In other embodiments, it can be adjusted according to the shape of the reaction arm of the hydraulic wrench.

The adjusting nut 9 is threadedly connected to the threaded column 17. The guide column 10 passes through the first through hole 11. The hole wall of the first through hole 11 fits the guide column 10. In the process of the stopper 7 moving up and down, the guide column 10 and the first through hole 11 cooperate to play a guiding role. In the torque test process of the hydraulic wrench, the guide column 10 is subjected to the torsion of the reaction arm to prevent the stopper 7 from moving in the horizontal direction. The threaded column 17 has a threaded portion matching the adjusting nut 9. The threaded portion The column can be a screw rod or a long bolt. After the adjusting nut 9 is threadedly connected with the threaded column 17, the stopper is placed on the adjusting nut 9. The adjusting nut 9 cooperates with the threaded column 17 to lift the stopper 7 to a suitable height position. In some specific embodiments, the surface of the guide column 10 is smooth, and a gap is left between the second through hole 18 and the threaded column 17 to facilitate the up and down movement of the stopper 7.

[0033] As a preferred embodiment, the hydraulic wrench torque testing platform of the present invention also includes a first scale arranged along the length direction of the sliding hole 3 and a second scale arranged along the length direction of the guide column 10. The first scale is used to record the distance between the first positioning member 4 and the side 8 of the block, and the second scale is used to record the height of the block 7.
