Abstract

The invention relates to an upper-pressing type mechanically-clamped indexable turning tool teaching aid based on 3D printing, which comprises a tool bar (1), a blade (2), a tool pad (3), a pin shaft (4), a compression screw (5) and a pressing plate (6), and can show the integral structure of an upper-pressing type mechanically-clamped indexable turning tool after assembly. All spare parts are printed through 3D and are accomplished, and cutter arbor (1), blade (2), shim (3), round pin axle (4), housing screw (5) and clamp plate (6) can demonstrate alone, also can assemble show overall structure. The parts are printed by adopting materials with different colors, so that the demonstration effect of the teaching aid is enhanced. The great part of size all adopts the hollow structure that 3D printed, and intensity is high and the quality is little. This teaching aid make full use of 3D printing technique is in the aspect of the model manufacturing advantage, and the component part and the overall structure of pressure formula machine clamp indexable turning tool on the show directly perceived have intensity height, quality little, no peculiar smell, clean environmental protection, low price, no material waste, advantage with low costs, can play fine classroom demonstration effect.

Description

Upper pressure type mechanically-clamped indexable turning tool teaching aid based on 3D printing

Technical Field

The invention relates to an upper-pressure type mechanically-clamped indexable turning tool teaching aid based on 3D printing, and belongs to the field of teaching instruments.

Background

The students for training the mechanical manufacturing engineering courses have the basic capabilities of reasonably selecting machine tools and determining the typical part machining method, and the students are the basis for the learning and respect of the special courses of numerical control machining and die design. Wherein knowledge of the knife requires that students be familiar with the knife structure. Most students need corresponding tool material objects and teaching aids as teaching aids due to weak basic knowledge of mechanical drawing and lack of space imagination. However, the tool object is small in size and difficult to demonstrate in class as a teaching aid, and the traditional tool model is usually manufactured by adopting an organic glass plate adhesion splicing method, so that the problems of less reflected section information, unreliable connection of components and low strength exist. The 3D printing technique, also known as additive manufacturing, is based on digital model files, and uses bondable materials such as metal powders or plastic wires to build objects by layer-by-layer printing. The technology is applied to the fields of mold manufacturing, model manufacturing in the field of industrial design and direct manufacturing of parts at a later time, and has application in the fields of automobiles, aerospace, medical treatment, education, geographic information, civil engineering and the like. With the maturity of desktop 3D printer technology and the reduction of material cost, the application in modeling is rapidly expanding. Therefore, based on the 3D printing technology, various teaching aid models are developed, a new idea is provided for the design and manufacture of teaching instruments, and the requirement of classroom teaching is better met.

Disclosure of Invention

The invention provides an upper-pressing type machine-clamped indexable turning tool teaching aid based on 3D printing, which makes full use of the advantages of a 3D printing technology in model manufacturing, visually displays the tool structure of an upper-pressing type machine-clamped indexable turning tool and better meets the requirements of classroom teaching.

The technical scheme adopted by the invention for solving the technical problems is as follows:

1. the utility model provides an go up pressure formula machine and press from both sides indexable turning tool teaching aid based on 3D prints, includes cutter arbor (1), blade (2), shim (3), round pin axle (4), housing screw (5) and clamp plate (6), can demonstrate the overall structure of pressure formula machine and press from both sides indexable turning tool after the assembly.

2. A but go up pressure formula machine clamp transposition lathe tool teaching aid based on 3D prints, its characterized in that: all spare parts are printed through 3D and are accomplished, and cutter arbor (1), blade (2), shim (3), round pin axle (4), housing screw (5) and clamp plate (6) can demonstrate alone, also can assemble show overall structure.

3. A but go up pressure formula machine clamp transposition lathe tool teaching aid based on 3D prints, its characterized in that: the parts are printed by adopting materials with different colors, so that the demonstration effect of the teaching aid is enhanced.

4. A but go up pressure formula machine clamp transposition lathe tool teaching aid based on 3D prints, its characterized in that: the great part of size all adopts the hollow structure that 3D printed, and intensity is high and the quality is little.

The beneficial effects obtained by the invention are as follows:

1. the components and the integral structure of the upper pressing type mechanically-clamped indexable turning tool are displayed by adopting a simple and visual three-dimensional model.

2. Each spare part all adopts 3D to print the manufacturing, satisfies the assembly accuracy requirement, and the assembly is firm and convenient to use, and the spare part adopts the material of different colours to print, can play better classroom demonstration effect.

3. The great part of size all adopts 3D to print hollow structure, and intensity is high and the quality is little, and the classroom of being convenient for is used, has no peculiar smell, clean environmental protection, low price, no material waste, advantage with low costs simultaneously.

Drawings

Fig. 1 is an upper pressing type mechanically-clamped indexable turning tool assembling model.

Detailed Description

The present invention will be further described with reference to the following examples.

Example 1 was carried out:

the device comprises a cutter bar (1), a blade (2), a cutter pad (3), a pin shaft (4), a compression screw (5), a pressing plate (6) and an upper pressing type mechanically-clamped indexable turning tool assembly model, as shown in figure 1. On the premise that the 3D printed part meets the assembling precision, the cutter pad (3) is pressed on the cutter bar (1) through the pin shaft (4), then the blade (2) is positioned above the cutter pad (3), the blade (2) is pressed on the cutter pad (3) through the pressing plate (6) and the pressing screw (5), the upper-pressing type machine-clamp indexable turning tool assembly is completed, and the component parts and the whole structure of the turning tool are displayed.
