Abstract
The invention discloses a fixed hinge point connection bolt shaft of a multi-rod mechanism. The fixed hinge point connection bolt shaft is simple in structure, low in machining cost and manufacturing cost, flexible to mount and convenient to dismount. The fixed hinge point connection bolt shaft comprises a rack, a bolt shaft body, a round nut, a standard hexagonal nut, a bearing and a bearing cover, wherein the bolt shaft body is screwed on the round nut in the rack; the back surface of the bolt shaft body is fastened by the standard hexagonal nut; one end of the bolt shaft body is arranged on the bearing in the rack; the clearance fit is adopted; the magnet bearing cover is arranged outside the bearing, and the axial positioning of the bearing on the bolt shaft body is realized; an outer ring of the bearing and the rack are in interference fit, and the axial positioning of a shaft system is realized; the fixed hinge point connection bolt shaft has the advantages that the axial positioning is stable, the height of a hinge point is convenient and liable to adjust, and daily class teaching demonstration requirements can be fully met.
Description
Technical field
The present invention relates to mechanical structure technical field, and specifically, it is a kind of multi-bar linkage fixed hinge point connecting bolt axle.
Background technique
Der Grundsatz der Maschinen is a special kind of skill basic course in the teaching programme of mechanical each specialty (undergraduate course), play from basic course excessively to specialized course, from theoretical property course excessively to engineering actual combine take over from the past and set a new course for the future act on, be one of the trunk class and degree class in series of machine course.The ABC that in all kinds of engineering goods of INTRODUCTION OF THE COURSE STRUCTURE, common mechanism designs, basic theories and basic skills, emphatically training student innovation ability, mechanical system scheme designed capacity.
Planar linkage is one of body matter of mechanics research, and main contents comprise: the fundamental property of four-bar linkage, planar linkage develop and motion analysis and comprehensive.Wherein, the fundamental property of four-bar linkage and linkage mechanism evolution are the souls of planar linkage, only have thoroughly understanding, expertly grasp, could provide favourable help for the study of follow-up specialized course and production practices.
The multimedia education produced along with computer technology, is the challenge of the model of teaching to traditional, teaching method, also brings opportunity to educational reform, both for student classroom adds teaching resource, has expanded teaching means, and has enriched again class teaching content.Mechanical principle course describes the theory and design method of various common mechanism, in conjunction with multimedia courseware, can show the application in productive life of various mechanism kinematic form and this mechanism, the distance of the theory and practice that furthers vividly.But although multimedia technology brings facility to education and instruction, can not abuse, otherwise can negative effect be produced, affect the understanding of student to knowledge.
Der Grundsatz der Maschinen is the course that a practicality is very strong, and Link of Practice Teaching is very important, can not only make student that knowwhy is converted into application expertise, can also strengthen Engineering Awareness, improves practical ability and cultivates creative thinking ability.Classroom teaching and practical teaching are the Liang Ge branches of this Teaching, on a par.In order to strengthen the cultivation of innovative consciousness of students and the ability of practice, Link of Practice Teaching must be strengthened.Creative thinking and practical competence are the bases that student moves towards society and succeeds, and practical ability is exactly the comprehensive of knowledge thinking and practice.Practical teaching link needs to launch by certain means and equipment, and the detailed process organizational form of education activities and teaching efficiency are all relevant with the equipment tool used in education activities.
In mechanical subject teaching, in order to demonstrate different form, simple structure and the movement mechanism of various mechanical motion, usually need some real experiment platforms, certain specific motion model is specialized, though existing experiment porch can realize this object in existing laboratory, carries out the demonstration of mechanism, but because it is bulky, extremely heavy, be inconvenient to carry, daily classroom cannot be climbed up and carry out teaching demonstration.
In order to solve existing test platform Problems existing, being simplified and innovate and be presented in face of classmates, enhancing sense organ impression personal understanding, deepens the anatomy to knowledge point and understanding.Need to provide one can be flexible for installation, be easy to dismounting, be convenient to mobile, classroom teaching, the demonstration of reliable and stable new teaching type can be applicable to.
Fixed hinge is the citation form be connected between component with frame, and the shaft part orientation type of transmission adopts bearing (ball) cover or tight fixed bolt, complex structure and be difficult to install.Because the multi-bar linkage for teaching demonstration adopts Ya Geli plate to make, quality is less, and movement velocity is not high, there is no need the structure adopting this kind of complexity.And axial delocalization can cause structural instability, adopt interference fit then can increase the difficulty of installation, dismounting.And the fixed hinge for connecting is the interference avoided between component, usually need the setting height(from bottom) adjusting hinge point, the pin shaft structure of transmission is difficult to meet this requirement.
Summary of the invention
Object of the present invention solves existing test platform Problems existing exactly, there is provided a kind of flexible for installation, be easy to dismounting, be convenient to mobile, be applicable to classroom teaching, reliable and stable, the multi-bar linkage fixed hinge point connecting bolt axle of daily classroom teaching demonstration needs can be met.
Wood of the present invention be realize like this, multi-bar linkage fixed hinge point connecting bolt axle comprises frame, bolt axis, round nut, standard hex nut, bearing and bearing cap, it is characterized in that: bolt axis is screwed on the round nut in frame, the back side is fastening by standard nut, one end of bolt axis is arranged on the bearing in frame, adopt Spielpassung, magnet bearing cap is installed in the outside of bearing, realize the axially locating of bearing in bolt axis, adopt interference fit between the outer ring of bearing and frame, realize the axially locating of axle system.
Advantage of the present invention is: axially locating is stablized, and the Height Adjustment of hinge point is convenient and easy, and structure is simple, manufacturing cost is low, flexible for installation, for convenience detach, fully can meet the needs of daily classroom teaching demonstration.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
Embodiment 1:
Bolt axis 4 of the present invention can be formed by plain bolt cutting, bolt axis 4 is screwed on the round nut 2 in frame 3, the back side is fastening by standard nut 1, one end of bolt axis 4 is arranged on the bearing 5 in frame 3, adopt Spielpassung, magnet bearing cap 6 is installed in the outside of bearing 5, realizes the axially locating of bearing 5 in bolt axis 1, adopt interference fit between the outer ring of bearing 5 and frame 3, realize the axially locating of axle system.During use, by adjustment bolt axis 4 and the connection of round nut 2, just can realize the Height Adjustment of hinge point, have structure simply, manufacturing cost is low, the feature of convenient and flexible installation.
