The utility model relates to the technical field of valve bevel
grinding machine spindles, in particular to an automatic balance spindle device for a valve bevel
grinding machine, which comprises a main body, and the top of the main body is fixedly connected with an adjusting component and a positioning component; according to the utility model, the horizontal position of the main shaft of the valve bevel
grinding machine is positioned under the action of the
laser transmitter and the
laser receiver, so that the main shaft can be balanced more quickly and accurately when being automatically balanced, and the positioning device is a non-contact positioning method, does not need to be in direct contact with a measured object, and is convenient to operate. According to the characteristic, damage or interference to a measured object is avoided, the
electric control actuator is used for receiving an inclination
signal and controlling the telescopic rod to stretch out and draw back, then inclination balance of the shaft rod can be adjusted, the purpose of automatically balancing the shaft rod is achieved, the length of the telescopic rod can be rapidly adjusted according to actual requirements, and the practicability is high. And the device is fixed at a required position through the locking device, and rapid stretching and locking are realized in an electric mode, so that the operation complexity is reduced.
