Description
Technical field
The present invention relates to metal cutting instructional technology field, especially a kind of lathe tool model for teaching demonstration.
Background technology
The cutter of a cutting tip processed, has by lathe tool for turning.Lathe tool is one of cutter most widely used in cut.The effect of lathe tool is exactly the excess metal layer excising on workpiece, and the cutting tip of general lathe tool is mainly made up of rake face, main rear knife face, minor flank, main cutting edge, front cutting edge and nose angle.The combination of the cutting tip of lathe tool and cutter hub (being clamping part) mainly contains monoblock type, welded type, mechanical clamping type and welding-mechanical clamping type.
Cutting-tool angle is the principal element that affects stock-removing efficiency and crudy, also be key factor, therefore in design, manufacture, when sharpening and measurement cutter, often need to control and guarantee cutting-tool angle, control and guarantee that cutting-tool angle must use orthogonal plane reference frame, i.e. three auxiliary planes, basal plane, principal section (being also orthogonal plane) and cutting plane, these three faces are emphasis in teaching, also be a teaching difficulty, at present, teacher is in the time of three auxiliary planes of explanation lathe tool, normally on blackboard, directly draw and explain, owing to being plan Drawing, need student to have stronger space imagining ability, therefore teacher can be very hard in explanation, student sounds that nature is also hard, so just make quality of instruction can not be guaranteed, knowledge explanation for lathe tool aspect is the problem of teacher's headache always, therefore be necessary to design a kind of teaching lathe tool model and solve this difficulties in teaching.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the technical matters that adopts plan Drawing explanation lathe tool knowledge to be difficult to be understood by student in existing teaching, provide a kind of time saving and energy saving in teaching process, student easily understands again the lathe tool model for teaching demonstration that also can strengthen impression directly perceived.
The technical solution adopted for the present invention to solve the technical problems is: a kind of lathe tool model for teaching demonstration, cutter head is slit into main cutting blade at principal section and the punishment of secondary section, front cutting edge portion, nose part and cutter head connecting portion, described main cutting blade is arranged on by web member on the secondary section of cutter head, described front cutting edge portion is arranged on by web member on the principal section of cutter head, described nose part is fixedly connected with front cutting edge portion with main cutting blade respectively between main cutting blade and front cutting edge portion and by web member, on described cutter head connecting portion, be positioned at principal section place and offer the first jack, in described the first jack, be equipped with the first slide bar, one end hinged front cutting edge portion of the first slide bar, on described cutter head connecting portion, be positioned at secondary section place and offer the second jack, in described the second jack, be equipped with the second slide bar, the hinged main cutting blade in one end of the second slide bar.The technical program is specialized lathe tool, cutter head is cut apart to assembling, by main cutting blade and nose part are together opened, so just can see intuitively secondary section, front cutting edge portion and nose part are together opened, just can see intuitively principal section, cutting plane and basal plane can intuitively be found out again on lathe tool mould, and abstract concept of space is specialized, and are conducive to student's understanding, also be convenient to teacher's explanation, thereby improve teaching efficiency.
The exposed portions serve tail end of described the first slide bar and the second slide bar is provided with for preventing that slide bar from skidding off the stop screw of jack.
For convenient manufacture processed, the detachable installation of described cutter hub and cutter head.
In order to reduce the weight of model, described cutter hub inside is hollow-core construction.
Swing bicycle knife mold during for the ease of explanation, described cutter hub bottom is provided with the support for fixing lathe tool.
For the ease of dismounting and easy to assembly, described web member is socket head cap screw.
The invention has the beneficial effects as follows, the lathe tool model for teaching demonstration of the present invention, its principal section, secondary section respectively all can be by the projection relation corresponding components that overturns, and tool has the following advantages:
1), simple in structure, easy accessibility, clear: to tap into row need to several flat sided straight of student explain and cut into piece, and then be assembled into tool bit part, and when explanation, split assembling, and can see clearly and want the plane seen.
2), time saving and energy saving, teacher and student doulbe-sides' victory: directly adopt explanation in kind being drawn at ordinary times the content of explaining on blackboard, material object is split to the method for similar dissection, abstract concept has been specialized, student, from having strengthened intuitively understanding, no longer dreams up, theoretical in conjunction with practice, deepen memory, therefore teacher is light again in teaching, and student has been raised again interest, and quality of instruction is also synchronously improved certainly.
Therefore the present invention has solved the difficult assurance of lathe tool teaching aspect teacher cleverly, and student's indigestible difficult problem hard to imagine, has increased the interest of imparting knowledge to students, and has strengthened the interaction between teachers and students.
