The invention discloses a reversible beam divergence angle mobile measurement mechanism. Through a reversible mechanism, a beam divergence angle measurement device can be moved out of a beam area after measurement or during the measuring process. The defect that beam divergence angle measurement is difficult and sensors and cables are easily short-circuited and damaged during long-term ignition of an ion thruster is solved. A rack is a double-layer structure: a rotating device is installed at the upper layer and the lower layer is a cavity with an opening. A crank is an inverted U-shaped structure. One arm of the crank is fixed on the rotating device, and the other arm of the crank is fixed on the beam divergence angle measurement device. In a test state, a test surface of the beam divergence angle measurement device is positioned in a test area and in a vertical state. When the beam divergence angle measurement device withdraws from the test, the rotating device rotates under the control of a stepper motor, and the crank drives the beam divergence angle measurement device to overturn downwards. The crank is contained into the second-layer cavity of the rack. The test surface of the beam divergence angle measurement device departs from the test area and is in a horizontal state.

The invention aims to provide a motor rotor positioning system for a hybrid vehicle and a positioning method thereof, which are suitable for the characteristics of a vehicle production line. The positioning system consists of a detection unit and a calibration unit, wherein the detection unit comprises a power device capable of driving a motor to be positioned to rotate, a detection host computer, a bar code scanner, a zero crossing detection device and a motor rotor position sensor arranged on the motor to be positioned, and the detection host computer is connected with the power device, the bar code scanner, the zero crossing detection device and the motor rotor position sensor; the calibration unit comprises another bar code scanner and a calibration host computer, and the calibration host computer is connected with a motor controller of the motor to be positioned; and the detection host computer and the calibration host computer are connected with a database server through a network respectively. The detection host computer detects the position angle value of the motor rotor through the zero crossing detection device and the motor rotor position sensor, transmits the position angle value to the calibration host computer, and further writes the position angle value into the motor controller so as to finish the positioning of the motor rotor.

The invention discloses a method for processing and assembling a riveted frame, comprising the following steps: independently processing a positioning support, a positioning joint, and a frame fixing bracket to size, including processing a unified processing and detection reference on the frame fixing bracket, and Process the precise positioning structure on the positioning joint and the positioning support; process the riveted clamp, and rough-machine the profile and mounting holes of the riveted clamp; assemble the positioning joint and the positioning support to the fixed bracket of the frame; After assembling the riveting clamps to the fixed bracket of the frame based on the precise positioning structure, the profile surface and mounting holes are finished according to the unified processing and inspection standard to size; after installing each locator to the mounting holes on the riveting clamping plate, the riveting clamp with locators The panels are then assembled to the jig fixing brackets.
