A kind of piston ring port repairment machine die sleeveTechnical field:
The invention belongs to the one of die sleeve, be specifically related to a kind of piston ring port repairment machine die sleeve.
Background technology:
Repairing mouth is requisite one procedure in piston ring production process, certainly be unable to do without use and repaiies a mouthful machine die sleeve, in the market repair a mouthful machineDie sleeve shape, material, structure are multifarious, and wearability is the most very poor, and the relative usage life-span is the shortest, and the sized precision of die sleeve internal diameter is the highest,Thus machining accuracy when reducing piston ring repair opening, in order to improve service life and the machining accuracy of piston ring port repairment machine die sleeve, therefore my inventionThis piston ring port repairment machine die sleeve.
Summary of the invention:
It is an object of the invention to provide a kind of piston ring port repairment machine die sleeve, simple in construction, easy to use, practical, anti-wear performance is good, easilyIn processing, piston ring repair opening machining accuracy is greatly improved.
For reaching above-mentioned purpose, one piston ring port repairment machine die sleeve of the present invention: it is connected spiral shell by die sleeve main body (1), die sleeve mouth (2), feather keyKeyhole (3,9), notch (4), ring-shaped step (5), lower fastening bolt holes (6), strut bolt hole (7), upper fastening bolt holes (8) is constituted,It is characterized in that: die sleeve main body be upper big under smaller Rotary-table, the side of die sleeve main body (1) has a notch (4), and notch (4) both sides are openedThere is lower fastening bolt holes (6), strut bolt hole (7), (8) three bolts hole of upper fastening bolt holes, lower fastening bolt holes (6) and upper fastening spiral shellThe hole of (8) two bolt pore area threads of keyhole is in the same side, and struts the hole of bolt hole (7) band thread at opposite side.
In technique scheme, described a kind of piston ring port repairment machine die sleeve, it is characterized in that: concave spherical is processed in the both sides of notch (4)Shape, it is therefore an objective to facilitate cutting abrasive wheel to retreat.
In technique scheme, described a kind of piston ring port repairment machine die sleeve, it is characterized in that: piston ring port repairment machine die sleeve inner headed face chromium plating,It is plated to one with die sleeve main body inner headed face.
In technique scheme, described a kind of piston ring port repairment machine die sleeve, it is characterized in that: the internal diameter of piston ring port repairment machine die sleeve can lead toCross down fastening bolt holes (6), strut bolt hole (7) and upper fastening bolt holes (8) triple interaction is adjusted.

Detailed description of the invention:
Below in conjunction with the accompanying drawings one piston ring port repairment machine die sleeve of the present invention is described in further detail；
As seen from Figure 1, this enforcement is a kind of piston ring port repairment machine die sleeve: it is by die sleeve main body (1), die sleeve mouth (2), feather key connecting boltHole (3,9), notch (4), ring-shaped step (5), lower fastening bolt holes (6), strut bolt hole (7), upper fastening bolt holes (8) is constituted,It is characterized in that: die sleeve main body be upper big under smaller Rotary-table, the side of die sleeve main body (1) has a notch (4), and notch (4) both sides are openedThere is lower fastening bolt holes (6), strut bolt hole (7), (8) three bolts hole of upper fastening bolt holes, lower fastening bolt holes (6) and upper fastening spiral shellThe hole of (8) two bolt pore area threads of keyhole is in the same side, and struts the hole of bolt hole (7) band thread at opposite side.
In the present invention, described a kind of piston ring port repairment machine die sleeve, it is characterized in that: concave spherical surface shape, mesh are processed in the both sides of notch (4)Be to facilitate cutting abrasive wheel to retreat.
A kind of piston ring port repairment machine die sleeve described in the technical program, is characterized in that: piston ring port repairment machine die sleeve inner headed face chromium plating, with die sleeve masterInternal disc is plated to one.
A kind of piston ring port repairment machine die sleeve described in the technical program, is characterized in that: the internal diameter of piston ring port repairment machine die sleeve can by lower tightlyFixing bolt hole (6), strut bolt hole (7) and upper fastening bolt holes (8) triple interaction is adjusted.
The Main Function of invention is to provide a kind of piston ring port repairment machine die sleeve, simple in construction, and easy to use, practical, anti-wear performance is good,Being prone to processing, piston ring repair opening machining accuracy is greatly improved.
