Description
Technical field
The utility model relates to grinding technique field, particularly relates to the portable end-face grinder of a kind of diesel engine upper cylinder half mouth.
Background technology
On engine cylinder block, cylinder holes seam plane there will be spot corrosion or erosion defect because of Long-Time Service, causes occurring drainage between seam plane and cylinder sleeve.And manufacture with repair-deficiency again by scene, meet the serviceability of engine, numerous engine maintenance worker endeavours the problem solved.Field maintenance adopts cold welding or imitation laser or the surface strengthening technology such as thermal spraying or built-up welding to be conventional measures usually.Needing by front processing to eliminate blemish before strengthening, and guarantee certain strengthening layer thickness, is the means that scene must adopt.
State Patent Office discloses and " on a kind of diesel engine cylinder holes seam plane lapping instrument " the license CN204053746U authorized.Which disclose cylinder holes seam plane lapping instrument on a kind of diesel engine, effectively can solve the problem that upper cylinder half hole seam plane removes burr, burr, the roughness precision of cylinder holes seam plane in raising, when making it install cylinder sleeve, contact surface is wider.This patent is mainly used in cylinder holes seam plane lapping on diesel engine, but its location is only by one side location, is difficult to the concentricity ensureing processing, and causes the wearing and tearing of cylinder inner wall, affect cylinder sleeve quality of fit, significantly limit the application of diesel engine field maintenance.
Summary of the invention
The utility model is for deficiency of the prior art, provide the portable end-face grinder of a kind of diesel engine upper cylinder half mouth, by endoporus centralized positioning, realize the axially accurate mobile of abrasive wheel and with endoporus Concentric rotation, carry out the on-the-spot precise finiss processing of end face, reach the technical requirements such as the size of regulation, precision and concentricity, and considerably improve on-site grinding working (machining) efficiency.
For achieving the above object, the present invention adopts following technical scheme:
The portable end-face grinder of a kind of diesel engine upper cylinder half mouth, it is characterized in that: there is locating ring, described locating ring downside end is the first pyramidal structure, described first pyramidal structure is combined with location tapered sleeve, locating ring upper side end is the second pyramidal structure, described second pyramidal structure is combined with locking tapered sleeve, the fastening lock-screw of realization is provided with between described second pyramidal structure and locking tapered sleeve, the fairlead for realizing centrally axle location movement is provided with in locating ring, guide cylinder is inner is used for stationary spindle by bearing, fairlead top is by tightened bolt presses bearing cap, axle is fastenedly connected by shaft coupling is concentric with electric rotating machine, abrasive disk is fixed in axle, electric rotating machine is placed on motor supporting base, motor supporting base is connected with the one-way precise module with servomotor, described one-way precise module is connected on module fixed support.
Compared with prior art, the utility model has following effectively effect: the portable end-face grinder of a kind of diesel engine upper cylinder half mouth, locating ring is realized concentric with inner bore of part by bottom location tapered sleeve and locking tapered sleeve, locking tapered sleeve and locating ring fastening is realized by lock-screw, prevent locating ring from rotating, effectively can pass through inner bore of part centralized positioning.By controlling electric rotating machine and one-way precise module, axially accurate mobile to realize abrasive disk, and realize the precise finiss to part end face by the rotary speed of regulation, to reach the technical requirement of regulation, complete the attrition process work of end face, to keep in repair at the scene or in process, to realize the on-the-spot precise finiss processing to seam end face on diesel engine, guarantee to process the size of end face, precision, concentricity and and the technical requirement such as flatness, promote on-the-spot processing or repair quality.
