Abstract
The invention discloses a servo hydraulic control system for a tensioning device. The servo hydraulic control system comprises a tensioning mechanism, a hydraulic tensioning spring, an electro-hydraulic servo valve, a system controller, a detection wheel of a detection mechanism, a tension sensor and a tension controller. The hydraulic tensioning spring is located at the left end of the tensioning mechanism and connected with the output end of the electro-hydraulic servo valve. The input end of the electro-hydraulic servo valve is connected with the output end of the system controller. The input end of the system controller is connected with the output end of the tension sensor. The tension sensor is located on the detection wheel of the detection mechanism. The tension controller is connected with the system controller and the tensioning mechanism. According to the servo hydraulic control system, fully-hydraulic control design is adopted, a costly servo motor is abandoned, and a hydraulic motor is adopted to achieve the constant tension function; and fully-hydraulic control is adopted, and the tension of a fretsaw is controlled in the manner that a closed loop is combined with hydraulic servo control.
Description
Technical field
The present invention relates to multi-line cutting machine lathe production equipment field, be specifically related to a kind of tensioning apparatus servo hydraulic control system.
Background technology
In present whole Machine Manufacture industry, the level of application of hydraulic technique on lathe is very high, but the type of the all-hydraulic technology of machine tool applications both domestic and external is very few, and now due to the progress of Numeric Control Technology, just gradually nibbled replacement.For multi-wire saw technology, use now the multi-wire saw lathe of all-hydraulic technology not occur, in further lathe, tensioning apparatus adopts also not occurring of servo hydraulic control system.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of tensioning apparatus servo hydraulic control system, and it effectively can realize the overall monitor to lathe ruuning situation and technological process.
In order to solve the problem, the present invention is by the following technical solutions: a kind of tensioning apparatus servo hydraulic control system, comprises strainer, tensioning hydraulic spring grease cup, electrohydraulic servo valve, system controller, the detection wheel of testing agency, tension pick-up, tension controller; Described tensioning hydraulic spring grease cup is positioned at the left end of strainer, and be connected with the output of electrohydraulic servo valve, the input of electrohydraulic servo valve is connected with the output of system controller, the input of system controller is connected with the output of tension pick-up, tension pick-up is positioned on the detection wheel of testing agency, and tension controller is connected with strainer with system controller respectively.
Operation principle of the present invention: in the process of sawing, the tension pick-up detected in testing agency under wheel detected for the tension force moment of scroll saw, and the tension force real output signal of detection is fed back to system controller, compare with initial given instruction force signal, the size of the opening amount of electromagnetic servo valve is adjusted by the deviation between actual signal and instruction signal, and then control the flexible of tensioning hydraulic spring grease cup, strainer is moved and reaches the object of identical tension.
Implement technical scheme of the present invention, there is following beneficial effect: multi-wire saw lathe of the present invention adopts all-hydraulic control design case, abandons the servomotor that price is high, adopt hydraulic motor to realize the function of identical tension.Used all-hydraulic control, its control mode be exactly adopt closed loop and hydraulic servocontrol to combine mode to reach the object of control line according to tension force.

Detailed description of the invention
Below with reference to the accompanying drawings 1 and in conjunction with the embodiments, the invention will be further described.
As shown in Figure 1, the invention provides a kind of tensioning apparatus servo hydraulic control system, comprise strainer 1, tensioning hydraulic spring grease cup 2, electrohydraulic servo valve 3, system controller 4, the detection wheel 5 of testing agency, tension pick-up 6, tension controller 7; Described tensioning hydraulic spring grease cup 2 is positioned at the left end of strainer 1, and be connected with the output of electrohydraulic servo valve 3, the input of electrohydraulic servo valve 3 is connected with the output of system controller 4, the input of system controller 4 is connected with the output of tension pick-up 6, tension pick-up 6 is positioned on the detection wheel 5 of testing agency, and tension controller 7 is connected with strainer 1 with system controller 4 respectively.
Operation principle of the present invention: in the process of sawing, detect the tension pick-up 6 under wheel 5 in testing agency the tension force moment of scroll saw is detected, and the tension force real output signal of detection is fed back to system controller 4, compare with initial given instruction force signal, the size of the opening amount of electromagnetic servo valve 3 is adjusted by the deviation between actual signal and instruction signal, and then control the flexible of tensioning hydraulic spring grease cup 2, strainer 1 is moved and reaches the object of identical tension.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, any people being familiar with this technology is in the technical scope disclosed by the present invention; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
