Technical Field

The invention relates to the field of hardware, in particular to a simple mechanical part.

Background

The machine tools such as a press machine, a grinding machine, a milling machine, a punching machine and the like are common machine tools in hardware, along with the increase of modern requirements, the machine tool technology needs to be improved, corresponding accessories also need to be improved, the existing mechanical parts are low in strength and cannot bear large pressure and rotating force, threads on the outer surface are pipe threads or triangular coarse threads, and the fixity is poor.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: in order to overcome the defects of the prior art, the mechanical part is provided, the part body is made of stainless steel, the strength of the part is improved, the part is firm and durable, wear-resistant and corrosion-resistant, the outer surface of the part body is provided with triangular fine threads, the self-locking performance is good, and the mechanical part has wide market prospect in popularization.

The technical scheme adopted by the invention for solving the technical problems is as follows: a machine part, comprising: the shaft body is cylindrical for the stainless steel, and the surface adopts the polishing to handle, the inside of shaft body is cylindrical drilling, and the internal surface adopts the dull polish to handle, the screw thread is for revolving internal thread the bilateral symmetry of shaft body distributes, and the degree of depth is the third of the thickness of shaft body, the screw thread is the fine screw thread of triangle, and the lead angle of screw is 30 degrees.

In a preferred embodiment of the invention, the outer diameter of the thread is less than 30mm and the length is less than 80 mm.

In a preferred embodiment of the invention, the surface roughness of the threads is 1.30 ~ 0.10.10 microns.

The invention has the beneficial effects that: the mechanical part has the advantages of simple structure, good fixity, easy and labor-saving operation, smooth surface, firmness, durability, wear resistance, corrosion resistance and the like, is beneficial to large-scale production, and is high in strength, hardness, firmness, durability and corrosion resistance by adopting the stainless steel to manufacture the body of the part; the triangular fine threads are adopted, so that the thread pitch and the lead angle are reduced, and the threads are good in fixity, firm and durable; compared with the common stainless steel surface treatment, the polishing treatment is adopted, so that the high strength, the wear resistance and the corrosion resistance of the part are improved. Has considerable prospect in the mechanical parts market.

Drawings

The invention is further illustrated with reference to the following figures and examples.

Fig. 1 is a schematic structural view of a mechanical part of the present invention.

In the figure: 1. axis body, 2, screw thread.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

As figure 1, axis body 1 is the stainless steel cylinder shape, and is sturdy and durable, wear-resisting corrosion-resistant, and cylindrical atress is even, can bear great pressure and turning force, and the surface adopts the polishing to handle, and intensity is high, and is stand wear and tear, and the surface is smooth and level, the inside of axis body 1 is cylindrical drilling, makes things convenient for the fixed of bearing, and the internal surface adopts the dull polish to handle, and is convenient durable, has reduced the cost of manufacture, screw thread 2 is the dextrorotation internal thread, and 2 indents of screw thread, and the symmetric distribution is in the both sides of axis body 1, the degree of depth are the third of the thickness of axis body 1, and the degree of agreeing with is good, screw thread 2 is the triangle fine thread.

The external diameter of the thread 2 is less than 30mm, and the length is less than 80 mm.

The surface roughness of the thread 2 was 1.30 ~ 0.10.10 microns.
