Abstract

The invention relates to a quick polishing device, which is used for grinding cylinders and comprises a main rod, grinding branches and grinding heads. The grinding branches are obliquely formed on the main rod in an axially staggered manner, and the grinding heads are disposed at ends of the grinding branches and are grinding head bodies capable of rotating along the grinding branches. The grinding branches are structurally designed into staggered oblique forms, accordingly, staggered oil storage pits are formed in an inner cavity of a cylinder liner conveniently, and the purpose of lubricating when a piston moves left and right is achieved. In addition, rotating sleeves are disposed on the grinding heads, accordingly, grinding grooves formed when the grinding heads are used for grinding are crescent, and the service lives of the grinding heads are prolonged. Furthermore, as the grooves are disposed on the grinding heads, the grinding heads are sharp when used for grinding. Besides, due to the reasonable structure and the crescent oil storage pits which are formed on the surface of the cylinder liner after the cylinder liner is ground, the quality of the cylinder liner is remarkably improved, and service performances of the cylinder liner are enhanced.

Description

A kind of brisk rub down device

Technical field

The present invention relates to a kind of grinding tool, specifically cylinder block is carried out a kind of brisk rub down device of rapid stock-removal.

Background technology

Through the relevant patent documentation of retrieval, do not retrieve a kind of brisk rub down device identical at present as yet with structure of the present invention.Existing automobile engine and internal combustion engine cylinders are added, carried out grinding to reach the required precision to the surface after generally taking man-hour to process.Because the wheel grinding grit of a part is squeezed on the inner surface of cylinder block during wheel grinding, make that in use for some time abrasive particle comes off step by step, thereby has aggravated the wearing and tearing between cylinder sleeve and the piston.Though seeing has the flexible grinding of employing that cylinder sleeve is processed; Can play on the cylinder sleeve surface and form a kind of microcosmic surface oil-stored hole, reach the purpose of oil storage, reduce the wearing and tearing between cylinder sleeve and the piston; But also since in grinding process grinding machine head and cylinder sleeve inside still be in a kind of rigid grinding; The abrasive particle that produces when making grinding is present on the cylinder sleeve surface, and because formed oil storage tank is in coherent state, makes the oil storage effect still not reach desirable effect.In order to improve the service life of cylinder sleeve, reduce the wearing and tearing of piston ring and cylinder sleeve, so be necessary to develop novel grinding attachment to improve the quality of cylinder sleeve further.

Summary of the invention

The objective of the invention is to provide a kind of improvement on existing grinding tool basis, have after grinding and can form a kind of micro-pit of intersection, and make micro-pit have more a kind of brisk rub down device of oil storage function on the cylinder sleeve surface.

Technical characterictic of the present invention is: considering that oil storage is effective, be designed to a kind of brisk rub down device of being made up of mobile jib, mill branch, bistrique on the basis easy to use, on mobile jib, be provided with the mill branch that interlocks and be formed slopely vertically; End at each mill branch is provided with bistrique; Described bistrique is can be along the grinding machine head body of mill branch rotation.

Described mill branch is an elastic cylinder.

Described mill branch is made up of mill end of the branch, branch bar, and the branch bar is fixed on the mobile jib, and the mill end of the branch is a body greater than the branch shank diameter, and the pivoted housing in mill end of the branch and the bistrique matches.

Described bistrique is made up of a body, groove, pivoted housing, is fixed with a body in the periphery of pivoted housing, and groove is arranged on the body, makes a body form the staggered grinding flute body that tilts; Described body is the grinding machine head body that abrasive particle and binding agent cementation form; Described groove tilts to be rotatably provided on the body.

During production, at first pivoted housing is processed, the mill end of the branch suit that will grind branch then is fixed in the pivoted housing, makes pivoted housing and mill end of the branch axial restraint, and pivoted housing is rotated along the mill branch; To grind branch again, pivoted housing puts into mould, and injects the body that mixes of abrasive particle and binding agent, and abrasive particle is solidificated on the pivoted housing, after baking and curing, forms bistrique; Again each is ground branch rotational fixation on mobile jib, the mill branch is staggered to be tilted on the mobile jib.

During use, mobile jib is fixed on electric drill or the drilling machine chuck, rotation drive mobile jib and mill end of the branch through electric drill are positioned over brisk rub down device of the present invention in the cylinder sleeve, and move back and forth along the cylinder sleeve axial direction, make bistrique carry out grinding at the cylinder sleeve inner chamber.Bistrique is provided with pivoted housing, its objective is to be provided with for bistrique when cylinder sleeve is carried out grinding rotation; Bistrique is provided with groove and its objective is in order to increase bistrique the grinding of cylinder sleeve inside is provided with; Mill branch is designed to a staggered structure that tilts, and its objective is in order to make after grinding the cylinder sleeve inner chamber form staggered netted cutting texture to be provided with.

Advantage of the present invention is; Because the mill branch is designed to the version of staggered inclination, thereby is convenient to form staggered oil-stored hole at the cylinder sleeve inner chamber, makes piston when carrying out move left and right, can both reach lubricated purpose; Owing on bistrique, be provided with pivoted housing, thereby the grinding flute that bistrique is formed is the version of crescent shape when grinding, and makes bistrique integral body obtain uniform grinding, improved the service life of bistrique; Owing on bistrique, be provided with groove, thereby grinding is sharper when making grinding, and the abrasive particle that comes off in the time of making grinding is simultaneously in time removed, and makes grinding more reliable; Because the cylinder sleeve surface forms meniscate oil-stored hole after rational in infrastructure, the grinding, and quality of the cylinder liner is obviously improved, and has improved the serviceability of cylinder sleeve; Because bistrique is provided with pivoted housing, thereby make grinding have more the characteristics of flexible grinding, make the metal surface after the grinding finer and close, and stress is eliminated; Since simple in structure, easy to use, so very big practical and popularizing value is arranged.
