Abstract

The invention relates to a forging machine, in particular relates to the velocity measurement of a motor rotor in the forging machine and particularly provides an installation method for a forging machine motor rotor and a photoelectric sensor. In the process provided by the invention, a motor and a radial grating sensor which is arranged on the motor and is used for transferring a control signalare utilized, wherein a bearing outer cover is arranged on the circumferential direction of the outer end part of the main shaft of the rotor, a screw hole is arranged on the bearing outer cover and is fixed together with a sensor bridge in a matching manner, the radial grating sensor is fixed at the central mouth of the sensor bridge and is fixed together with the bearing outer cover through thesensor bridge, a rotor hinge pin extends outwards with the same axle center of the main shaft of the rotor, the radial grating sensor extends inwards to be provided with sensor small shaft, and an interference connector is arranged between the rotor hinge pin and the sensor small shaft for transition, so that the radial grating sensor can be electrically connected with the motor rotor. According to the invention, the problem of control failure caused by the eccentric radial grating sensor existing in the existing forging machines is solved.

Description

technical field [0001] The invention relates to a forging machine tool, in particular to a rotor speed measurement control of a motor in the forging machine tool, specifically a method for installing the motor rotor and a photoelectric sensor of the forging machine tool. Background technique [0002] The sensor used by the forging machine tool is a circular grating sensor with an aperture of φ8mm, and the diameter of the rotor shaft of the motor is φ160mm, such as figure 1 As shown, the current installation method is to process an M8 threaded hole on the rotor shaft, and connect the circular grating sensor to the rotor shaft with M8 screws. The screw connection cannot guarantee concentricity, and it is easy to loosen during the vibration process. , the circular grating sensor is off-center, and the information fails, which leads to the control failure. Contents of the invention [0003] The purpose of the present invention is to provide a method for installing the motor r...
