Abstract
The utility model is related to a kind of resilient tool finished for aperture for 1~4mm apertures, it is characterised in that：Resilient tool is the step bars of two cylinders of size connection composition, wherein small cylinder grooving be divided into above and below two valves, epivalve (1) has the projection of ridges, and raised height is not more than 3mm；Hypovalve (2) is the straight rod of semicircle fitted with epivalve.This patent can preferably solve the High-precision that small surplus aperture is 1~4mm apertures and finish, and operating method is simple, and the high precision after processing, the qualification rate of part brings up to 100% by 70%.In field of machining, it is related to the utility model improvement to traditional milling tool.By making suitable milling tool, coordinate grinding method to substantially increase the processing stability and machining accuracy of parts with small hole.Qualification rate brings up to 100% by 70%, with larger actual application value and economic benefit.
Description
Technical field
This patent is related to a kind of resilient tool finished for aperture for 1~4mm apertures with Ginding process.
Background technology
The characteristics of attrition process has simple machining accuracy height, equipment, small input, instant effect, so in production scene quilt
It is widely used, as shown in figure 1, the widely used porting instrument in scene is the mode of milling bar+grinding sleeve, it is cylindrical by milling bar
Grinding sleeve size, and then attrition process hole in piece part are adjusted with the taper of grinding sleeve endoporus and mutual alignment.But work as bore dia
During less than or equal to 4mm, the porting tool making difficulty of this structure is greatly increased, and crudy straight line declines, and qualification rate is only
Have 70% or so, be badly in need of by exploitation simply, effectively grinding aperture tool and method and carrying out the following aperture essences of effective resolving aperture 4mm
Processing problems.
The content of the invention
The purpose of the invention：In order to overcome existing processing scheme to meet the following aperture finishing of aperture 4mm
The problem of can be simple there is provided one kind, method for finishing manufactured effectively is ground for 1~4mm apertures to aperture, to processor
Technical merit requirement be not very high, it is possible to increase be processed hole crudy.
The technical solution of the utility model：One kind Ginding process finishing aperture is the elastic lap tool work of 1~4mm apertures
Tool, is described in detail as follows：
1st, a kind of for the resilient tool that aperture is the finishing of 1~4mm apertures, resilient tool is that two cylinders of size connect
Connect the step bars of composition, wherein small cylinder grooving be divided into above and below two valves, epivalve (1) has the projection of ridges, raised height
Degree is not more than 3mm；Hypovalve (2) is the straight rod of semicircle fitted with epivalve.
2nd, resilient tool as claimed in claim 1, the diameter of resilient tool small cylinder is less than the aperture in hole to be processed
The A/F of hypovalve is 0.1-0.3mm on 0.5mm~1mm, resilient tool small cylinder.
3rd, resilient tool as claimed in claim 1 or 2, resilient tool makes of 40Cr or 45# Steel materials.
The small cylindrical car of leading portion is broken to needing after size during manufacture, centre, which is put into after rod iron, to be tied up at opening with steel wire
Tightly, heat treatment quenching and tempering is sent afterwards, can form the projection of ridges, raised height is not more than 3mm, for micro-pore grinding.Grind
Grinding pressure is obtained by the raised crimp of ridges during mill.
The beneficial effects of the utility model：Processing method of the present utility model can resolving aperture be preferably that 1~4mm is small
Hole is ground finishing, and operating method is simple, can process allowance within 0.02, dimensional tolerance, form and position tolerance, thick
The higher part of rugosity, qualification rate brings up to 100% by 70%.
Brief description of the drawings
Fig. 1 is conventional milling bar, grinding sleeve figure；
Fig. 2 is to process part drawing with resilient tool.
Embodiment
The utility model method is described in further detail below by embodiment：Specific procedure of processing is such as
Under：
As depicted in figs. 1 and 2, a kind of for the resilient tool that aperture is the finishing of 1~4mm apertures, resilient tool is big
The step bars of small two cylinders connection composition, wherein small cylinder grooving be divided into above and below two valves, epivalve 1 has the convex of ridges
Rise, raised height is not more than 3mm；Hypovalve 2 is the straight rod of semicircle fitted with epivalve.The diameter of resilient tool small cylinder is less than
The A/F of hypovalve is 0.1-0.3mm on the aperture 0.5mm~1mm in hole to be processed, resilient tool small cylinder.Resilient tool
Made of 40Cr or 45# Steel materials.
This tool operation method is simple, being capable of the higher part of processing dimension tolerance, form and position tolerance, roughness.But work
Have elastic force limited, be not suitable for big surplus porting processing, be suitable for the porting processing below 0.02 surplus.
