Description
Technical field
The utility model relates to a kind of experiment table of mechanical engineering technical field, specifically is a kind of slider-crank mechanism parameter measurement experiment table.
Background technology
The mechanism kinematic parameter measurement is a base level experiment of mechanical principle course, also is the important education experiment that mechanical major must be opened.In the past owing to lack testing table and test macro, then be the principle and the method for the displacement of giving the student explain measuring mechanism on the classroom, speed, acceleration, the student is taken action on one's own, to such an extent as to do not realize the implication and the experimental technique of experiment, thereby influenced the understanding that theory is known.
Through the new discovery of looking into to prior art, the crank guide rod slider cam combination experiment system that Hangzhou stars Instrument and Equipment Company releases, this is one group of integration test experiment table, but there is following shortcoming in it: one, complicated in mechanical structure, overall dimensions are bigger, there are two dead-centre positions in the mechanism, quite easily stuck so that do not reach experiment effect in operation process; Its two, crank can not intuitively reflect in this device, directly has influence on teaching efficiency.In further retrieving, find identical with the utility model theme or similar bibliographical information as yet.
The utility model content
The utility model provides a kind of slider-crank mechanism parameter measurement experiment table at the deficiencies in the prior art and defective, makes that it is simple in structure, size is less, easy to operate, can obviously express the single institution kinetic characteristic, is difficult for stuck in operation process.
The utility model is achieved through the following technical solutions, the utility model comprises: extension rod, joint, crank disc, second connecting rod, end rod bearing acceleration transducer, slide block, displacement transducer, guide rail, base, second motor, adjusting bolt, its connected mode is: second motor links with bolt and base.Crank disc is allocated on the output shaft of second motor; Regulate bolt and both cooperated, embed again in the chute of crank disc and move up and down with extension rod.The connector by using screw thread links with extension rod and second connecting rod respectively; Second connecting rod then links with the end rod bearing with screw thread again.The end rod bearing is installed in the groove of slide block with screw; Slide block is placed in the shifting chute of guide rail, can move left and right; Guide rail uses bolt to be cemented on the base.Crank disc, connecting rod and slide block are formed slider-crank mechanism.Acceleration transducer and displacement transducer are attached on the slide block respectively with screw.
Sensor connects by signal secondary instrument, computing machine, display, forms complete test macro.
Motor is a driving link, drives slider-crank mechanism and moves.At this moment, the acceleration transducer and the displacement transducer that are attached on the slide block also move as linear reciprocation, the mechanical quantity of the velocity variations when acceleration transducer moves the slide block straight line is converted into the variation of electric weight, displacement variable when displacement transducer moves the slide block straight line is converted into the variation of electric weight, signal is input to secondary instrument amplifies and data processing, the utility model adopts electrical measuring method measuring mechanism kinematic parameter, its essence and means are exactly (as displacement with mechanical quantity, speed, acceleration) variation, be converted into electric weight (as electric current by sensor, voltage) variation, amplify and data processing through electric signal again, use computer, display, printer is shown and record.
The utility model experiment table has solved a series of master datas tests of the kinematics of machinery and the isolated plant of analyzing kinetic characteristic, and has established certain basis with dynamic (dynamical) relevant subject study and mechanism kinematic innovative experiment for the kinematics of four-bar linkage.The utility model is simple in structure, size is less, easy to operate, can obviously express the single institution kinetic characteristic, in operation process, be difficult for stuck.Saved cost greatly, made the student obtain benefit gained from others' wisdom widely in knowledge such as theory of mechanisms, Electric Traction and speed governing, non electrical quantity test philosophy, Computerized real-time data acquisition and analysis, Fundamentals of Sensors and application, secondary instrument application and type selectings.
