Problems solved by technology

Since the three spindles are affected by factors such as resistance, impact, or system pressure changes during the movement, the distribution of oil volume also changes accordingly, and the synchronization is difficult to guarantee.
Due to the many uncertain factors in the hydraulic system itself, coupled with the influence of human adjustment errors and other factors, it is quite difficult to operate to ensure the synchronization accuracy of the three spindles

Abstract

The invention provides a tri-spindle synchronizer, which is characterized in that sliding bearings are respectively arranged on positions corresponding to a front end cover and a rear end cover; two ends of a drive shaft and a driven shaft which are arranged in parallel are arranged in the holes of the sliding bearing; three oil cavities and two clapboards are fixedly arranged between the front end cover and the rear end cover, and the clapboard is arranged between the oil cavities; an oil inlet is arranged in the middle oil cavity, and an oil outlet is respectively arranged on the other end of each of the oil cavity; an oil cavity passes through all the oil cavities and the clapboards and is communicated with the oil inlet; three drive wheels are arranged on the drive shaft, three driven wheels which are engaged with the drive wheels correspondingly are arranged on the driven shaft, and one pair of engaged gears are arranged in one oil cavity; and each oil cavity is provided with a high-pressure cavity and a low-pressure cavity.

Description

technical field [0001] The invention relates to a three-spindle synchronization device, in particular to a device for controlling the flow consistency of three oil circuits in a three-spindle hydraulic system. It belongs to the field of machinery manufacturing. Background technique [0002] At present, to complete the synchronous centering movement of the three spindles, manufacturers generally use hydraulic drive. Its structure is that the three main shafts are respectively controlled by independent speed regulating valves to control the equivalent of the oil flow in the oil cylinders of the corresponding main shafts to ensure the centering movement of the three main shafts. Since the three spindles are affected by factors such as resistance, impact or system pressure changes during the movement, the oil distribution will also change accordingly, and the synchronization is difficult to guarantee. Due to many uncertain factors in the hydraulic system itself, coupled with t...
