Besides, the motion characteristics of a single mechanism can be expressed obviously, and the utility model can not be easy to block in the process of running.
Description
Technical field
The utility model relates to a kind of mechanism kinematic parameter measurement experiment table, specifically is a kind of crank and rocker mechanism parameter measurement experiment table.Be used for mechanical engineering technical field.
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 crank and rocker 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: two frame linking pole sockets, two side links, two end rod bearings, connecting rod, sensor, channel-section steel, bearing seat, base plate, motor, cushion block, its connected mode is: motor links to each other with base plate with bolt by cushion block.First frame linking pole socket is allocated the output shaft of motor into, and another frame linking pole socket matches with bearing seat; Two side links are respectively with two frame linking pole sockets and the threaded connection of two end rod bearings; Same respectively two the end rod bearings of connecting rod are with threaded connection.Two side links and connecting rod are formed crank and rocker mechanism, and channel-section steel is connected with bolt with bearing seat and base plate respectively.Sensor is installed on second side link with securing member.
Sensor connects secondary instrument, computing machine, display by signal wire, forms complete test macro.
First side link claims crank again, and second side link claims rocking bar again, and two side links, connecting rods are formed crank and rocker mechanism, and motor is a driving link, drives crank and rocker mechanism and rotates.
The driven by motor crank and rocker mechanism rotates, at this moment, be attached at sensor on second side link (rocking bar) and also do the angular displacement swing, sensor is converted into the variation of electric weight with the variation of the angular acceleration of second side link (rocking bar), 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 the variation with mechanical quantity (as displacement, speed, acceleration), be converted into the variation of electric weight (as electric current, voltage) by sensor, amplify and data processing through electric signal again, shown and write down the result of test with computer, display, printer.
The utility model is tested platform and has been 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.
