Description
Technical field
The utility model relates to a kind of marine engine oil head bushing dismounting tool, belongs to and builds ship technical field.
Background technology
" Sha Li " takes turns during main frame repairs, and main frame cylinder head goes to other unit to renovate to return to go on board after installation terminates, find when oil head is installed in Seiko oil head cover lower plane by light low cause oil head lower plane and oil head overlap plane contact less than, gas leakage oil leakage phenomenon can be produced like this.This extracts oil head cover with regard to needs and processes, and because installation site is narrow and small, oil head cover generally adopts interference fits, and conventional construction method workshop is entered in whole cylinder head dismounting handling remove again, such wasting manpower and material resources.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of marine engine oil head bushing dismounting tool, and its structure is simple, easy to operate, effectively improves efficiency of construction and has saved construction cost.
The purpose of this utility model is achieved in that a kind of marine engine oil head bushing dismounting tool, it comprises two columns in left and right, described column top is provided with alignment pin, top board is set with between two alignment pins in left and right, described top board center is coated with screw mandrel, described screw mandrel upper end is connected with top board by the second nut, described screw mandrel lower end is provided with the connector of a back taper, described connector is provided with the connector of two semicylinder shapes, the connector center of described semicylinder shape offers bellmouth, described bellmouth matches with the connector of back taper, the connector outer surface of described semicylinder shape is annular knurl face, pad and the first nut is provided with above described connector.
Compared with prior art, the utility model has following beneficial effect:
A kind of marine engine oil head of the utility model bushing dismounting tool, its structure is simple, easy to operate, effectively improves efficiency of construction and has saved construction cost.
