Abstract
The invention discloses a mechanical part comprising a shaft body and screw threads, wherein the shaft body is of a stainless steel cylinder, the surface of the stainless steel cylinder is polished, a cylindrical drill hole is formed in the shaft body, and the inner surface of the cylindrical drill hole is sanded; the screw threads are internal right-handed threads and symmetrically distributed at two ends of the shaft body, the depth of each screw thread is a half of the thickness of the shaft body, each screw thread is a fine triangular thread, and the lead angle is 30 DEG. In such a way, the mechanical part disclosed by the invention has the advantages of simple structure, good self-locking performance, benefit for large-scale production, simplicity and labor conservation in operation, surface smoothness, firmness and durability, wear resistance, corrosion resistance and the like so as to have wide market prospect for popularization.
Description
Technical field
The present invention relates to the five metals field, particularly relate to a kind of mechanical parts.
Background technique
The lathes such as grinding machine, milling machine, punch press, press are the most frequently used precision machine tools in five metals field, along with improving constantly of secret machine tool technology, its corresponding accessory also needs to change thereupon, existing bearing Machine Components Strength is lower, Chang Buneng bears larger pressure and rotatory force, the screw thread of outer surface is often pipe thread or triangle coarse-pitch thread in addition, and self-locking performance is poor.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of mechanical parts,, by using stainless steel finished parts body, increases part strength, sturdy and durable, wear resistant corrosion resistant, outer surface adopts the triangle fine thread, self-locking performance is good, popularizing of mechanical parts, market prospects is widely arranged.
For solving the problems of the technologies described above, the invention provides a kind of mechanical parts, comprising: axis body and screw thread, described axis body are that stainless steel is cylindrical, polishing treatment is adopted on surface, the inside of described axis body is cylindrical bore, and internal surface adopts frosted to process, and described screw thread is the dextrorotation internal thread, be symmetrically distributed in the two ends of described axis body, the degree of depth is half of thickness of axis body, and described screw thread is the triangle fine thread, and lead angle is 30 degree.
In a preferred embodiment of the present invention, the external diameter of described screw thread is less than 25mm, and length is less than 100mm.
In a preferred embodiment of the present invention, the surface roughness of described screw thread is 1.25 ~ 0.08 microns.
The invention has the beneficial effects as follows: mechanical parts of the present invention have simple in structure, the advantages such as self-locking performance good, be conducive to mass production, laborsaving, surfacing simple to operate, sturdy and durable, wear resistant corrosion resistant, on mechanical parts universal, market prospects are widely arranged.
Description of drawings
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of mechanical parts one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, axis body, 2, screw thread.
Embodiment
Below will the technological scheme in the embodiment of the present invention be clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skills, not making all other embodiments that obtain under the creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
A kind of mechanical parts comprise: axis body 1 and screw thread 2.
described axis body 1 is that stainless steel is cylindrical, sturdy and durable, wear resistant corrosion resistant, cylindrical stressed even, can bear larger pressure and rotatory force, polishing treatment is adopted on surface, intensity is high, wear-resistant, smooth surface is smooth, the inside of described axis body 1 is cylindrical bore, facilitate the fixing of bearing, internal surface adopts frosted to process, convenient durable, reduced fabricating cost, described screw thread 2 is the dextrorotation internal thread, screw thread 2 indents, be symmetrically distributed in the two ends of described axis body 1, the degree of depth is half of thickness of axis body 1, compatible degree is good, described screw thread 2 is the triangle fine thread, lead angle is 30 degree, lift angle is little, self-locking performance is good.
The external diameter of described screw thread 2 is less than 25mm, and length is less than 100mm.
The surface roughness of described screw thread 2 is 1.25 ~ 0.08 microns.
The classify beneficial effect of booking software of the present invention is:
One, by adopting stainless steel to make the body of part, thereby make the intensity of part high, hardness is high, sturdy and durable, corrosion-resistant;
Two,, by adopting the triangle fine thread, reduce pitch and lift angle, thereby make the self-locking performance of screw thread good, sturdy and durable;
Three, process with respect to general stainless steel surfaces, adopt polishing treatment here, thereby increased the high strength of part, wear-resistant, decay resistance.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in scope of patent protection of the present invention.
