Abstract
The present invention relates to a kind of split type round broach teaching aid based on 3D printing, including pull end, neck, transition cone, front pilot, rough cut tooth, finish cutting tooth, accurate tooth and rear pilot, rough cut tooth, finish cutting tooth and calibration toothed portion carry out cutting along intermediate cross-section.Cross section between each separate structure can show that the cross sectional shape and size of broaching tool different piece, sectional cross section can show the form of rough cut tooth, finish cutting tooth and finishing teeth, and the overall structure of broaching tool can be shown after assembling.Section between each separate structure is embedded in strong magnets, and the assembling for realizing each separate structure of broaching tool is attracted by magnet, is firmly combined and easy to use, and each separate structure uses the file printing of different colours, enhances the demonstrating effect of teaching aid.It is mutually attracted the back side of magnet between adjacent two separate structure equipped with antifreeze plate, excludes the interference between the non-pull magnet of two adjacent groups.All separate structures are the hollow structure of 3D printing.The teaching aid makes full use of advantage of the 3D printing technique in terms of model manufacturing, the intuitive cutter structure for showing round broach, have the advantages that intensity is high, quality is small, free from extraneous odour, it is clean it is environmentally friendly, cheap, without waste of material, at low cost, good class demonstration effect can be played, improves student to the acceptance of cutter knowledge.
Description
Technical field
The present invention relates to a kind of split type round broach teaching aid based on 3D printing, belongs to instruments used for education field.
Background technique
Mechanical manufacturing engineering course training student, which has, reasonably selects lathe, cutter and determining typical part processing method
Basic capacity, be the fixed basis of study honor of numerical control processing, mold design specialized courses.Wherein about the understanding of cutter, it is desirable that
Student is familiar with cutter structure.Most students are since mechanical drawing rudimentary knowledge is weak, and space imagining ability shortcoming is in addition in kind
The smaller specific structure for being difficult to be envisioned as cutter of the cutting tip of cutter.Traditional cutter teaching mode is viscous using poly (methyl methacrylate) plate
Even joining method production, has that reflected cross section information is few, and the connection of component part is not convenient and reliable enough, and intensity is lower to ask
Topic.3D printing technique is also named " increasing material manufacturing ", it, can with powdery metal or plastic etc. based on digital model file
Jointing material constructs object by layer-by-layer printing.Early stage is for mold manufacture, the model system of industrial design field
It makes, is gradually available for the direct manufacture of components later, the technology is in jewelry, footwear, industrial design, building, engineering and construction, vapour
Vehicle, aerospace, dentistry and medical industries, education, GIS-Geographic Information System, civil engineering, gun and other field are answered
With.With the reduction of the maturation and cost of desktop type 3D printer technology, the application field in terms of modelling is rapid
Expand.Therefore it is based on 3D printing technique, various teaching aid model exploitations is carried out, one kind will be provided for the design of instruments used for education and production
New thinking better meets classroom instruction demand.
Summary of the invention
The present invention provides a kind of split type round broach teaching aid based on 3D printing, makes full use of 3D printing technique in model
The advantage of manufacture view, the intuitive cutter structure for showing round broach, better meets classroom instruction demand.
The technical solution adopted by the present invention to solve the technical problems is:
1. a kind of split type round broach teaching aid based on 3D printing, including pull end, neck, transition cone, front pilot, rough cut
Tooth, finish cutting tooth, accurate tooth and rear pilot, rough cut tooth, finish cutting tooth and calibration toothed portion carry out cutting along intermediate cross-section.
A kind of split type round broach teaching aid based on 3D printing described in 2., it is characterised in that: the cross between each section
Section can show the cross sectional shape and size of broaching tool different piece, sectional cross section can show rough cut tooth, finish cutting tooth and
The form of finishing teeth can show the overall structure of broaching tool after assembling.
3. a kind of split type round broach teaching aid based on 3D printing according to claim 1, it is characterised in that:
Section between each separate structure is embedded in strong magnets, and the assembling for realizing each separate structure of broaching tool is attracted by magnet, in conjunction with
Secured and easy to use, each separate structure uses the file printing of different colours, enhances the demonstrating effect of teaching aid.
4. a kind of split type round broach teaching aid based on 3D printing according to claim 1, it is characterised in that:
It is mutually attracted the back side of magnet between adjacent two separate structure equipped with antifreeze plate, excludes dry between the non-pull magnet of two adjacent groups
It disturbs.
5. a kind of split type round broach teaching aid based on 3D printing according to claim 1, it is characterised in that:
All separate structures are the hollow structure of 3D printing.
Beneficial effect obtained by the present invention is:
1. showing the overall structure and cutter tooth shape of round broach using intuitive threedimensional model and corresponding seperated and cutting structure
State.
2. being attracted between each separate structure by the strong magnets of insertion, it is firmly combined and easy to use, each separate structure
Using the file printing of different colours, good class demonstration effect can be played, improves student to the acceptance of cutter knowledge.
3. being mutually attracted the back side of magnet between adjacent separate structure equipped with antifreeze plate, the non-pull magnet of two adjacent groups is excluded
Interference, guarantee good actuation effect.
4. all separate structures are the hollow structure of 3D printing, intensity is high and quality is small, uses convenient for classroom, has simultaneously
Have the advantages that free from extraneous odour, it is clean it is environmentally friendly, cheap, without waste of material, at low cost.
Detailed description of the invention
Fig. 1 is broaching tool composition model.
Specific embodiment
The present invention is further described below with reference to embodiment.
Embodiment 1:
This embodiment device include the split type round broach teaching aid based on 3D printing each separate structure and cross section,
Sectional cross section and the whole displaying of assembling, as shown in Figure 1.The solid tool structure that round broach is shown by composition model, by tearing open
The shape and size for dividing cross section to show broaching tool different piece section pass through the cutter tooth form that sectional cross section shows round broach.
