The invention relates to detection equipment, in particular to equipment for detecting the rotating torque force of a sawtooth-shaped transmission thread. The invention provides a technical scheme asfollows: the equipment for detecting the rotating torque force of a sawtooth-shaped transmission thread comprises a base, and a clamping device, a torque sensor and a motor are sequentially arranged on the base; couplers are respectively arranged at the two axial ends of the torque sensor; an output shaft of the motor is connected with the torque sensor through one coupler, and the torque sensor can be connected with a screw rod with a sawtooth-shaped thread through the other coupler; the base is provided with an installation cavity corresponding to the clamping device; and the clamping devicecomprises two clamping pieces arranged oppositely and sliding sleeves connected with the clamping pieces in a telescopic mode, the sliding sleeves are arranged on supporting rods in a sliding mode, the two supporting rods are arranged in parallel and fixed in the installation cavity respectively, and the sliding sleeves are provided with shaft holes matched with the supporting rods correspondingto the supporting rods. The equipment can be used for detecting the torque force required by the rotation of the sawtooth-shaped transmission thread.
Description
technical field [0001] The invention relates to a detection device, in particular to a device for detecting the rotational torque force of a saw-tooth transmission thread. Background technique [0002] Drive threads include trapezoidal threads, rectangular threads, and serrated threads. Among them, the zigzag thread is used to transmit one-way power. Generally, it is installed on the screw rod with zigzag thread and the screw rod adapted to the screw rod. The screw rod rotates relative to the screw sleeve under the drive of the motor, so that the screw sleeve can move linearly along the screw rod. [0003] Ideally, when the motor drives the screw with sawtooth thread to rotate relative to the screw sleeve, the speed of the motor is the speed of the screw. However, due to the existence of the torque force of the sawtooth transmission thread, the rotation of the screw relative to the screw sleeve will be hindered, affecting the rotation of the screw. Rotational speed, thereb...
