The force part 8 can be positioned in the claw 3 in a circumferential direction, and the torque sensor 4 can sense the torque value acting on the claw 3 and transmit the torque value to the control system. The control system includes a controller, a storage module, a receiving module, an analysis module and a data output module. The storage module is used to store preset torque value range data, the receiving module is used to receive the detection data transmitted by the torque sensor 4, the analysis module is used to analyze and calculate the detection data received by the receiving module and the torque value range data stored in the storage module and obtain the detection result. The data output module can output the detection result and detection data to the outside, and the controller controls the start and stop of the torque output device.

[0025] During the test, the mechanical component 7 to be tested is manually placed on the mechanical component positioning device 6 for positioning. The part 8 on the mechanical component 7 to be tested that needs to detect the installation torque is clamped on the clamp for positioning. The torque output device drives the torque sensor 4 to rotate, and then the rotational torque of the parts after tightening on the mechanical component is detected, and a qualified judgment and data recording are made. A start button and an emergency stop button can also be set on the equipment to facilitate operation and emergency handling.

[0026] The torque output device is located below the testing platform 2. A hollow structure 9 is provided on the testing platform 2, and the claw 3 extends above the testing platform 2 through the hollow structure 9. Placing the torque output device below the testing platform 2 does not interfere with the loading and positioning of the mechanical component 7 to be tested, occupies little space, and facilitates loading and unloading.

[0027] The fixed frame 1 is also fixedly mounted with a lifting drive device. The movable end of the lifting drive device is capable of upward and downward telescopic movement. A torque bracket 11 is fixedly mounted on the movable end of the lifting drive device. The torque output device is fixedly mounted on the torque bracket 11. The upward and downward telescopic movement of the movable end enables the claw 3 to move up and down. The controller also controls the start and stop of the lifting drive device. When not in the testing state, the lifting drive device drives the claw 3 downward to facilitate the loading and positioning of the mechanical component 7 to be tested. After the loading of the mechanical component 7 to be tested is completed, the lifting drive device drives the torque output device, torque sensor 4, and claw 3 to rise together. The claw 3 engages the rotating end part of the mechanical component, and the torque test begins.

The pads 33 are made of a material with a certain degree of elasticity to prevent damage to the part 8 on the mechanical assembly, which requires installation torque detection. The chamfered structure on the pads 33 guides the part 8 on the mechanical assembly, which requires installation torque detection.

The contact sensing device 14 is electrically connected and communicates with the control system.

[0031] When the torque applied to the claw 3 is greater than the maximum torque that the part 8 on the mechanical component that needs to detect the installation torque can withstand, the part will rotate, and the claw 3 will rotate. The contact sensing device 14 that is positioned in the circumferential direction of the claw 3 will touch the limit pin 15, and the control system will control the torque output device to stop.

[0032] The mechanical component positioning device 6 and the clamp are respectively provided with a first induction sensor 16 and a second induction sensor 17. The first induction sensor 16 and the second induction sensor 17 can respectively sense the mechanical component positioned in the mechanical component positioning device 6 and the part 8 that needs to detect the installation torque positioned in the clamp. The first induction sensor 16 and the second induction sensor 17 are respectively electrically connected to the controller of the control system for communication.

[0033] When the first sensing sensor 16 and the second sensing sensor 17 respectively sense the mechanical component positioned in the mechanical component positioning device 6 and the part 8 that needs to detect the installation torque positioned in the clamp, the control system can control the torque output device to start, to prevent the mechanical component and the test part thereon from not being positioned properly, and starting the torque output device to damage the mechanical component.
