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 definite says, 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 mechanical each specialty (undergraduate course) teaching programme, play from basic course excessively to specialized course, from theoretical property course excessively to the effect of taking over from the past and setting a new course for the future with the actual combination of engineering, be one of trunk class in series of machine course and degree class.In all kinds of engineering goods of INTRODUCTION OF THE COURSE STRUCTURE, ABC, basic theories and the basic skills of common mechanism design, cultivate emphatically creative ability for students, 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 evolution and motion analysis and comprehensive.Wherein, it is the soul of planar linkage that the fundamental property of four-bar linkage and linkage mechanism develop, and only has thoroughly and understands, expertly grasps, and could provide favourable help for study and the production practices of follow-up specialized course.
The multimedia education producing along with computer technology, is to traditional model of teaching, the challenge of teaching method, also to educational reform, has brought opportunity, both, for student classroom has increased teaching resource, has expanded teaching means, has enriched again class teaching content.Mechanical principle course has been introduced the theory and design method of various common mechanisms, in conjunction with multimedia courseware, can show the application in productive life of various mechanism kinematic forms and this mechanism, the distance of the theory and practice that furthers vividly.Although but multimedia technology has been brought facility to education and instruction, can not abuse, otherwise can produce negative effect, affect the understanding of student to knowledge.
Der Grundsatz der Maschinen is a course that 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 branch of this Teaching, on a par.In order to strengthen the cultivation of innovative consciousness of students and the ability of practice, must strengthen Link of Practice Teaching.Creative thinking and to put into practice practical ability be that student moves towards the basis that society succeeds, practical ability is exactly the comprehensive of knowledge thinking and practice.Practical teaching link need 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 of using in education activities.
In mechanical course teaching, in order to demonstrate different forms, 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 be realized this object in existing laboratory, carried out the demonstration of mechanism, but bulky because of it, extremely heavy, be inconvenient to carry, cannot climb up daily classroom and carry out teaching demonstration.
The problem existing in order to solve existing test platform, is simplified and innovate be presented in classmates in face of, enhancing sense organ impression personal understanding, intensification is to the anatomy of knowledge point and understanding.Need to provide a kind of can be flexible for installation, be easy to dismounting, be convenient to mobilely, can be applicable to classroom teaching, reliable and stable new teaching type demonstration.
Fixed hinge be member with frame between the citation form that is connected, 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 to adopt the structure of this class complexity.And axially delocalization meeting causes structural instability, adopt interference fit can increase the difficulty of installation, dismounting.And be the interference of avoiding between member for the fixed hinge connecting, conventionally need to adjust the setting height(from bottom) of hinge point, the pin shaft structure of transmission is difficult to meet this requirement.
summary of the invention
Object of the present invention is exactly to solve the problem that existing test platform exists, provide a kind of flexible for installation, be easy to dismounting, be convenient to mobile, be applicable to classroom teaching, reliable and stable, can meet the multi-bar linkage fixed hinge point connecting bolt axle of daily classroom teaching demonstration needs.
Wood of the present invention be to 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, between the outer ring of bearing and frame, adopt interference fit, realize the axially locating of axle system.
Advantage of the present invention is: axially locating is stable, and the Height Adjustment of hinge point is convenient and easy, simple in structure, manufacturing cost is low, flexible for installation, for convenience detach, can fully 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, between the outer ring of bearing 5 and frame 3, adopt interference fit, realize the axially locating of axle system.During use, by adjusting being connected of bolt axis 4 and round nut 2, just can realize the Height Adjustment of hinge point, have simple in structure, manufacturing cost is low, the feature of convenient and flexible installation.
