As shown in fig. 1 and 2, the electric tool locked-rotor torque force testing device provided in this embodiment includes an air cylinder 1, a rack 2, a gear 3, a torque sensor 4, an angle device 5, a connector 6 and a PLC controller, an output head of the air cylinder 1 is connected to the rack 2, the rack 2 is in meshing contact with the gear 3, the axle 301 of the gear 3 is provided with the torque sensor 4 and the angle device 5, the connector 6 is fixed to a terminal of the axle 301, and the PLC controller is connected to the air cylinder 1 and is used for controlling the air cylinder 1.
The air cylinder pushes the rack by utilizing air pressure, the rack and the gear are meshed with each other, the rack drives the gear to rotate, and the connector on the gear shaft is connected with a sample to provide a reverse resistance for the sample. Thus, the resistance of the air cylinder source is transmitted to the sample through the rack and the gear, and the sample is given with accurate reverse resistance.
The data of the torque sensor 4 and the angle device 5 are sent to the PLC controller in a wired or wireless mode, and the PLC controller controls the operation of the air cylinder 1 according to the data and a set value.
During testing, the operation steps are as follows:
1. and (4) coaxially connecting the rotating shaft of the test sample with the connecting head.
2. And determining the air pressure of the locked-rotor torque required by the air cylinder.
3. The control power supply of the test sample is switched on, and the switch button of the test sample, namely the electric tool, is manually pressed.
4. The maximum torque of the power tool between 30 ° and 60 ° is determined and recorded.
The utility model aims at testing electric tool's stifled commentaries on classics maximum torque, the resistance source comes in controllable pressure's cylinder, and the rack is connected to the cylinder, and the rack drives the gear, installs torque sensor and angle gauge and connector on the gear shaft, and the sample is connected to test equipment through the connector on. The sample start button is manually pressed, and the sample start button can stop at 30-60 degrees due to the resistance of air pressure, and the sensor can detect the maximum torque between 30-60 degrees. I.e. test data are obtained for the purpose of standard testing.
It is noted herein that while the above describes example embodiments of the patent, these descriptions should not be viewed in a limiting sense. Rather, several variations and modifications are possible without departing from the scope of the present patent as defined in the appended claims.
