Abstract
The utility model discloses a grinding device for an inner bore surface, which comprises a lathe, a grinding rod and a grinding sleeve, wherein one end of the grinding rod is connected with a tailstock of the lathe while the other end is connected with the grinding sleeve; the grinding sleeve is used for grinding the inner bore surface of parts; a through slot and at least one groove are arranged on the axial periphery of the grinding sleeve; and a spiral slot for storing a grinding paste is arranged on the radial periphery of the grinding sleeve. The grinding device provided by the utility model is especially used for grinding the inner bore surface of the parts; by grinding, hidden channels and pores on the inner bore surface of the parts are extruded and plugged, so that the quality of the inner bore surface of the parts is optimal and the air leakage of the inner bore surface of the parts is effectively prevented; the grinding device is especially suitable for grinding the inner bore surface of the parts with high air-tightness demand and also is suitable for grinding other common inner bore surface of the parts; and the grinding device has the characteristics of reasonable design, simple structure, convenience in operation, high efficiency, quickness, high reliability, strong practicability, and the like.
Description
Technical field
The utility model relates to the lapping device of part endoporus; It specifically is a kind of bore area lapping device; It is especially suitable for use as grinds the demanding part bore area of gas tightness; For example urceolus endoporus of undercarriage oil gas buffer etc. also is suitable as other common parts bore area is ground.
Background technology
Be equipped with buffer (also claiming damper) on the undercarriage of aircraft; Aircraft is when high ski-running is run on touchdown moment or the runway in injustice; With ground violent bump takes place, except that pneumatic tire can play the fraction cushioning effect, most of Impact energy will lean on buffer to absorb.Using the widest buffer on the present generation aircraft is the oil gas buffer.
The oil gas buffer requires very high to gas tightness, do not allow the urceolus of buffer to have gas leak phenomenon, in order to prevent the gas leakage of buffer urceolus; Common solution is that the chromium plating bore area to urceolus carries out honing, and nonetheless, still there is slight gas leak phenomenon in most buffer urceolus; Cause product quality defective, have potential safety hazard, need carry out the fine processing of multiple operation repeatedly; Seriously delayed the product delivery time, the regular traffic that has directly influenced enterprise is carried out.
Summary of the invention
The purpose of the utility model is: to the deficiency of above-mentioned prior art; A kind of simple to operate, practical bore area lapping device is provided; This device is especially suitable for use as the demanding part bore area of gas tightness is ground; Can effectively improve the bore area quality, prevent the gas leakage of part bore area.
The technical scheme that the utility model adopts is: a kind of bore area lapping device; Comprise lathe, milling bar and grinding sleeve; One end of said milling bar is connected on the tailstock of lathe, and the other end connects grinding sleeve, and said grinding sleeve is as the bore area that grinds part; The axial periphery of said grinding sleeve is provided with a groove and at least one groove, and the circular radial side face of grinding sleeve is provided with the helicla flute as the storage abrasive pastes.
The end that said milling bar connects grinding sleeve is a male cone (strobilus masculinus), and tapering is 1:50, and said grinding sleeve has the taper hole that the male cone (strobilus masculinus) with milling bar is complementary.
The end that said milling bar connects tail stock is a Morse taper shank.
The beneficial effect of the utility model is: above-mentioned lapping device grinds as the part bore area specially; Through grinding; The trickle secret tunnel hole that the part bore area is existed pushes, shutoff, makes the quality of part bore area reach optimum state, can effectively prevent the gas leakage of part bore area; Be especially suitable for use as the demanding part bore area of gas tightness is ground, also be suitable as other common parts bore area is ground.It has characteristics such as reasonable in design, simple in structure, easy to operate, efficient quick, reliability be high, practical.
