Abstract
The invention relates to a micro step hole structure. The micro step hole structure comprises a basal plate, and step holes formed in the basal plate, wherein the adjacent hole diameter difference of the step holes is 0.01-0.1 mm. Compared with the prior art, the micro step hole structure has such advantages as improvement of production efficiency, wide use range and high product pass percent.
Description
Technical field
The present invention relates to a kind of step hole, especially relate to a kind of micro-step hole structure.
Background technique
The Conventional processing methods in current hole is: brill, expansion, hinge, boring four kinds, the hole circle cylinder that these four kinds of processing methods process is the concentric circle geometry set of equal diameters, as illustrated in fig. 1 and 2.That is being equal with the upper and lower diameter in hole that traditional processing method processes, even if there is the unequal result of upper and lower diameter, is also artificially uncontrollable.So just determine hole machined once overproof will causing is done over again or scrapped, scrapping is exactly the waste of cost increase and resource.
Summary of the invention
Object of the present invention is exactly provide a kind of to overcome defect that above-mentioned prior art exists to improve manufacturing efficiency, using scope is wide, conforming product rate is high micro-step hole structure.
Object of the present invention can be achieved through the following technical solutions:
A kind of micro-step hole structure, it is characterized in that, comprise substrate and be located at the step hole on substrate, the adjacent apertures difference of this step hole is 0.01 ~ 0.1mm.
The adjacent apertures difference of described step hole is 0.04mm.
The cylinder bore that described step hole is increased successively by three diameters is formed by connecting.
Described step hole is processed by hole milling mode.
Compared with prior art, the present invention has the following advantages:
1, improve manufacturing efficiency, due to a hole be designed to three diameters not wait cylinder bore, the diameter dimension in hole divides three intervals, like this axle assembled with hole or the requirement of selling diameter dimension are lowered, improve the assembling degree of conformity of hole and axle or pin, namely reduce scrapping because of axle or the axle sold overproof and cause or pin part in production process, namely reduce cost of production, accelerate and produce joint and gather.
2, using scope is wide: this technology can be applicable to the numerically controlled machine equipment such as high-precision digital control milling machine, machining center and turning milling center;
3, facts have proved that hole machined size qualification rate is high, do over again few, at the bottom of scrappage.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram in existing hole;
Fig. 2 is the plan structure schematic diagram in existing hole;
Fig. 3 is sectional structure schematic diagram of the present invention;
Fig. 4 is plan structure schematic diagram of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As shown in Figures 3 and 4, a kind of micro-step hole structure, the step hole comprising substrate 1 and be located on substrate, the adjacent apertures difference of this step hole is 0.01 ~ 0.1mm.
The cylinder bore that described step hole is increased successively by three diameters is formed by connecting, and be respectively lower cylindrical hole 23, middle cylindrical hole 22 and upper cylindrical hole 21, its diameter is respectively D3, D2 and D1.Such as the hole of φ 50mm x30mm ± 0.05, φ 50.04mm x10mm+ φ 50mm x10mm+ φ 49.96mm x10mm tri-sections of cylindrical bodys can be designed to according to tolerance.
Described step hole is processed by hole milling mode.Hole milling is a kind of new hole forming method, and it will be applied to the processing method in hole as a kind of new processing method.Reason is that the numerically controlled machine equipment such as current high-precision digital control milling machine, machining center and turning milling center have spread in machining industry.
Embodiment 2
The adjacent apertures difference of described step hole is 0.04mm.Other are with embodiment 1
Embodiment 3
The adjacent apertures difference of described step hole is 0.1mm.Other are with embodiment 1.
Claims (4)
1. a micro-step hole structure, is characterized in that, comprises substrate and is located at the step hole on substrate, and the adjacent apertures difference of this step hole is 0.01 ~ 0.1mm.
2. the micro-step hole structure of one according to claim 1, is characterized in that, the adjacent apertures difference of described step hole is 0.04mm.
3. the micro-step hole structure of one according to claim 1, it is characterized in that, the cylinder bore that described step hole is increased successively by three diameters is formed by connecting.
