Description
The utility model relates to dynamo-electric driving, specifically a kind of lead screw gear.
At present, in electromechanical driving system, as robot, parallel machine tool and numerical control machine tool etc., use lead screw transmission in the Transmitted chains under many circumstances, it is very important therefore improving its control performance.The factor that influences the lead screw transmission dynamic performance mainly contains the external disturbance of lead screw transmission, friction (as starting friction) and the vibration that causes because of its structural rigidity factor etc., and how the influence that solves these factors from control is the prerequisite in highi degree of accuracy applications lead screw transmission.The vibration of adopting mechanical passive damping device to suppress lead screw transmission is arranged in the prior art, solve perturbed problem, solve the influence of lead screw transmission internal system friction by friction modeling and Model Distinguish by the Robust Adaptive Control strategy.Characteristics such as these methods exist in realization and are difficult to accurate modeling, control strategy complexity, and amount of calculation is big.
In order to overcome above-mentioned deficiency, the utility model provides the lead screw gear that a kind of antijamming capability is strong, the track following precision is high.
To achieve these goals, the technical solution of the utility model is: be made up of the motor that leading screw is housed, guide rail, slide block, force transducer, grating chi, described motor is placed on the pedestal by supporting member, the grating chi is parallel with leading screw, be fixed on the pedestal, establish a slide block that force transducer is housed on the leading screw, one acceleration transducer is installed on the described slide block, and described acceleration transducer is electrically connected with circuit for controlling motor.
Its working principle is:
The utility model is improving on the dynamo-electric control performance that drives, and utilizes the acceleration transducer feedback control can effectively increase the bandwidth of the active damping of lead screw transmission, and disturbance suppression improves the precision and the rigidity of lead screw transmission to the influence of system.
The utlity model has following advantage:
The utility model adopts acceleration transducer partly to be connected with Electric Machine Control, and motor is implemented feedback information control, and the static friction power in the time of can effectively overcoming the lead screw transmission startup reduces the track following error of the section of startup; Effectively disturbance suppression strengthens the robustness that drives lead screw transmission, i.e. the disturbance rejection ability to the influence of lead screw transmission; Force transducer described in the utility model in addition can also realize that lead screw transmission level and smooth stable contacted transient and steady state force tracking phase in the contact force control procedure are insensitive to disturbance.
