Abstract
The invention discloses a four-bar mechanism for teaching which comprises a rack plate, a jiggle bar, a crank, a connecting rod and a rocker, wherein the crank, the connecting rod, the rock and the rack plate are respectively provided with round holes, and sequentially form movable fit in pairs, and one end of the jiggle bar penetrates through the hole of one end of the rack plate to be fixedly connected with the crank. The four-bar mechanism is used as a teaching aid, can be used for effectively exercising the benchwork skill of students, and is also beneficial to the intuitive understanding of various characteristics of the four-bar mechanism.
Description
Technical field
The present invention relates to a kind of four-bar mechanism that is used to impart knowledge to students.
Background technology
Usually the processing of the pincers in mechanical major skill training is through letting the student adopt the concavo-convex pattern plate that matches of method processing and fabricating of sawing and filing to implement.For letting the student well grasp filing, size Control technical ability, often to practise repeatedly.Such training is more uninteresting to the student.Cause learning interest not high thus, it is slower that technical ability improves speed.
Summary of the invention
The purpose of this invention is to provide a kind of four-bar mechanism that is used to impart knowledge to students, improve the effect of pincers processing skill training.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of four-bar mechanism that is used to impart knowledge to students; Comprise frame plate, crank handle, crank, connecting rod and rocking bar; Circular hole is all arranged on crank, connecting rod, rocking bar, the frame plate; Crank, connecting rod, rocking bar, frame plate constitute movingly successively in twos, and hole and crank formation that an end of crank handle passes frame plate one end are fixedly linked.
Crank, connecting rod, rocking bar, frame plate constitute movingly successively in twos, can realize through circle cotter pin and screw.
Further, on crank, connecting rod, rocking bar, the frame plate a plurality of circular holes can be arranged, can change the kinetic characteristic of four-bar mechanism, can demonstrate crank and rocker mechanism, double-crank mechanism, double rocker mechanism etc. through connecting the circular hole of diverse location.
Frame plate, crank, rocking bar, connecting rod are that certain thickness steel plate is arranged.
Four-bar mechanism of the present invention uses as educational aid, has following beneficial effect:
(1) four-bar mechanism mid frame plate of the present invention, crank, rocking bar, connecting rod, especially when adopting certain thickness steel plate, its processing is the pincers worker technical ability of exercise student ' effectively, especially trains sawing, filing and boring technical ability;
(2) after four-bar mechanism of the present invention completed, the student got information about the various characteristics of four-bar mechanism through various combinations.To clamp the processing training and combine, not only improve learning interest but also improved learning efficiency with the mechanical principle knowledge learning.
Description of drawings
Fig. 1 is the four-bar mechanism axonometric drawing that is used to impart knowledge to students of the present invention;
Fig. 2 is the four-bar mechanism part decomposition axonometric drawing that is used to impart knowledge to students of the present invention;
Wherein: 1-frame plate, 2-crank handle, 3-circle cotter pin, 4-crank, 5-connecting rod, 6-screw, 7-rocking bar.
Embodiment
Below in conjunction with specific embodiment the present invention is set forth in detail.
As depicted in figs. 1 and 2; A kind of four-bar mechanism that is used to impart knowledge to students; Comprise frame plate 1, crank handle 2, crank 4, connecting rod 5, rocking bar 7; On frame plate 1, crank 4, connecting rod 5, the rocking bar 7 circular hole more than 2 is arranged all; Crank 4, connecting rod 5, rocking bar 7, frame plate 1 constitute movingly through round cotter pin 3 and the screw 6 that passes circular hole on it successively in twos, and an end of crank handle 2 becomes the hexagonal hole of hexagon and crank 4 one ends to match, and an end of crank handle passes the hole of frame plate 1 one ends and linking to each other of crank 4.
Can pass through the circular hole of diverse location on connecting crank 4, connecting rod 5, rocking bar 7, the frame plate 1, change the kinetic characteristic of four-bar mechanism.
Four-bar mechanism can be demonstrated crank and rocker mechanism, double-crank mechanism, double rocker mechanism etc. through different connecting portions.
In reality is given a lesson process; Can let the student with reference to four-bar mechanism teaching aid of the present invention,, assemble again with pincers worker technical ability maker frame plate, crank, connecting rod, rocking bar and crank handle; Can improve pincers processing technical ability effectively, help to understand intuitively the various characteristics of four-bar mechanism simultaneously.
