Abstract
The utility model discloses a control device used for a double oil supply system and simultaneously allowing a double oil cylinder to synchronously work. The control system comprises a device body. Two parallel connection pipelines and a straightly connection pipeline are formed in the device body, two end portions of each parallel connection pipeline are respectively an oil inlet and an oil outlet, the two oil outlets are respectively communicated with a pipe body of the straightly connection pipeline, and two end portions of the straightly connection pipeline are two oil supply ports. An adjusting pipeline vertically communicated with the straightly connection pipeline is further formed in the middle, corresponding to the two parallel connection pipelines, of the device body. An adjusting bolt capable of stretching into the straightly connection pipeline and adjusting oil flow in the straightly connection pipeline is adaptively assembled in the adjusting pipeline. Through the fine adjustment control of stretching-out quantity in the straightly connection pipeline through the adjusting bolt, hydraulic oil inside the straightly connection pipeline achieves self balance adjustment by means of self fluid characteristics of the hydraulic oil under the fine adjustment control, and thus damping of the parallel connection pipelines is larger than that of the straightly connection pipeline but smaller than the backpressure caused by imbalance of external load, two systems simultaneously work and synchronously operate, and double oil cylinder high-precision synchronous working is truly achieved.

Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
This novel a kind of control gear that supplies simultaneously two oil cylinder synchronous workings for two oil supply systems that relates to, shown in Fig. 1-2, it is a device body, be formed with two parallel pipelines 1 and connecting leg road 2 always in this device body, two parallel pipelines 1 are and are arranged side by side, always connecting leg road 2 and the 1 perpendicular setting of two parallel pipelines, and consist of one " Qian " type shape structure.The two end part of two parallel pipelines 1 respectively are a filler opening 11 and an oil outlet 12, two filler openings 11 extend to respectively the surface of device body, for the respectively adaptive connection of extraneous two oil supply systems, two oil outlets 12 are formed in the device body, and respectively with the corresponding connection of the pipe shaft of described direct-connected pipeline 2.The two end part of described direct-connected pipeline 2 are two oil-feed ports 21, and they also extend to respectively the surface of device body, suitably connect respectively for extraneous two oil cylinders.
Also be formed with on the described device body and regulate pipeline 3, this regulates pipeline between two parallel pipelines 1, the neutral position between two parallel pipelines 1 preferably, and should regulate pipeline 3 equally with direct-connected 2 perpendicular connections of pipeline, regulate the interior adaptive regulation cock 4 that can carry out to the oil in the direct-connected pipeline 2 Flow-rate adjustment that is assembled with of pipeline 3, particularly, regulation cock 4 can stretch into or the direct-connected pipeline 2 that contracts in activity, to regulate flowing of direct-connected pipeline 2 interior hydraulic oil.Further, regulation cock 4 can be designed to: after regulation cock 4 stretches into direct-connected pipeline 2 to greatest extent, the sealed partition of hydraulic oil of direct-connected pipeline 2 corresponding regulation cock both sides and restricted circulation, this moment, the caliber of described adjusting pipeline 3 was identical with the caliber of direct-connected pipeline 2, and be concaved with the deep gouge that the end with regulation cock 4 is complementary on the madial wall that direct-connected pipeline 2 and the end of regulation cock 4 are faced mutually, particularly, the end of regulation cock 4 can be designed to be cone-shaped, be concaved with a cone-shaped deep gouge 22 on the madial wall of corresponding direct-connected pipeline 2, the cone-shaped end of regulation cock 4 can the above-mentioned deep gouge 22 of adaptive insertion, has strengthened thus the sealing modulability of 4 pairs of direct-connected pipelines 2 of regulation cock.In addition, ooze out from regulating pipeline 3 in order to prevent the hydraulic oil in the direct-connected pipeline 2, also be arranged with seal ring 41 on the described regulation cock 4, the sealing circle closely is sticked with the madial wall of regulating pipeline 3.
