Abstract

The invention discloses a control method of a hydraulic rotary table. The control method comprises the following steps of acquiring the rotation position information of the rotary table and calculating to obtain an expected output pressure value and an expected output flow value; respectively outputting actual pressure and actual flow according to the expected output pressure value and the expected output flow value; acquiring an actual pressure value and judging whether the expected output pressure value is equal to the actual pressure value or not; if no, calculating the difference value of the expected output pressure value and the actual pressure value; and outputting the corrected pressure according to the difference value. The invention also discloses a hydraulic rotary table system. In addition, the invention also discloses an injection molding machine comprising the hydraulic rotary table system. The control method of the hydraulic rotary table is additionally provided with an output pressure and position feedback link, so that the actual pressure value and the actual position are additionally subjected to corrected pressure output, and furthermore the rotary table is precisely controlled.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a hydraulic turntable system. The invention also relates to an injection molding machine with the hydraulic turntable system. In addition, the present invention also relates to a method for controlling the turntable of the hydraulic turntable system. Background technique [0002] With the rapid development of my country's economic construction, the market demand for injection molding machines with hydraulic turntable systems is increasing. [0003] As we all know, the commonly used turntable drive methods in the market include electric turntable and hydraulic turntable. Among them: the electric turntable usually includes a servo driver, a servo motor, a reducer, a reduction gear and a turntable, and the servo driver and the servo motor are used to precisely control the rotation speed of the turntable. The hydraulic turntable usually includes a hydraulic motor, a ...
