Description
Technical field
The utility model relates to a kind of high speed Crankshaft of Marine Diesel Engine mounting surface and hole system processing unit (plant)s, are mainly used in
Diesel engine part processing technique field.
Background technique
The processing of middle high speed diesel engine crankshaft balance weight face and hole system is typically more fixed on traditional equipment, draws first flat
Then weight face processing line goes to boring machine centering workpiece and manually rotates to Working position progress face milling, in conversion phase
During need again by line centering, balance weight face is balanced repeated hole system scribing process again after processing is completed, is finally transferred to general
The processing of equipment progress hole system.Process is tedious, complicated for operation, high labor cost.
Utility model content
Technical problem to be solved by the utility model is: providing a kind of high speed Crankshaft of Marine Diesel Engine mounting surface and hole system
Processing unit (plant), easy to operate, high in machining efficiency, saving processing cost, solves the conjunction in multi items crankshaft balance weight face and hole system
And processing problems, save the interspersed operation between process.
High speed Crankshaft of Marine Diesel Engine mounting surface described in the utility model and hole system processing unit (plant), including pedestal, bottom
Dividing head Mobile base and hydraulic tailstock is respectively set in the both ends of seat, installation NC dividing head at the top of dividing head Mobile base, on pedestal
Fixed support and adjustable Auxiliary support are distributed between dividing head Mobile base and hydraulic tailstock, the top of fixed support is respectively set
The phase terminal pad of corresponding connection is arranged in hydraulic clamp arm, corresponding NC dividing head.
The fixed support and adjustable Auxiliary support arranged for interval.
The medial surface medium position of the phase terminal pad and hydraulic tailstock is respectively set top.
The adjustable Auxiliary support includes support portion and adjustment portion, and support portion is connected with pedestal, setting at the top of adjustment portion
Arc, bottom are arranged screw rod, nut are arranged on screw rod, and screw rod setting internal thread hole, support portion and adjustment portion are corresponded in support portion
It is connected through a screw thread.
The fixed support includes the support portion of bottom and the positioning region at top, and positioning region and hydraulic clamp arm form circle
Shape cavity.
The processing unit (plant) is using clamped one time processing balance weight face and hole system, and the determination of initial phase is by boss
Uniform datum hole determines, ensure that the accuracy of phase；It is adjusted not by adjusting the height of fixed support and Auxiliary support
Center with kind crankshaft is high；In addition, to reduce error caused by human intervention, workpiece initial alignment turns after determining in phase
The operation for changing compression is all made of hydraulic realization, and is all hole system cutters of chip removal problem of guarantee in process using interior cold
Cutter had both improved the processing quality that stock-removing efficiency in turn ensures hole system.
The beneficial effects of the utility model are:
The processing method of the high speed Crankshaft of Marine Diesel Engine balance weight face and hole system is applicable to the song of multi items type
Axis processing has many advantages, such as easy to operate, high in machining efficiency, saving processing cost, in actual application more original processing
60% is improved in mode efficiency, and reduces the expenditure cost of two operators.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, NC dividing head；2, phase terminal pad；3, hydraulic clamp arm；4, hydraulic tailstock；5, dividing head is mobile
