Machine tool rotation system capable of assisting heat dissipation and control method
The invention discloses a machine tool rotation system capable of assisting heat dissipation and a control method, the input end of a PTO device is connected with a power take-off port of an engine or a main pump, and the output end of the PTO device drives a variable displacement piston pump to rotate. An inlet of the variable displacement piston pump sucks oil from the hydraulic oil tank, and an outlet of the variable displacement piston pump is connected with an oil port P of the reversing valve set. And the reversing valve group reverses the hydraulic oil to the rotary accessory according to a control signal output by the controller and then returns to the hydraulic oil tank through the radiator, or reverses the hydraulic oil to the radiator and returns to the hydraulic oil tank. The controller receives signals of the instrument, the control handle and the oil temperature sensor, carries out mode judgment and outputs corresponding control signals to the variable displacement piston pump and the reversing valve set. According to the invention, on-demand flow supply is realized, and the machine adaptability is improved; the auxiliary heat dissipation function is achieved, and the hydraulic oil high-temperature risk is effectively reduced. The rotation requirement of the machine tool is met, hydraulic oil circulation can be accelerated, and the auxiliary heat dissipation effect is achieved.
