Description

Low-speed diesel engine frame guide plate process unit

Technical field

The utility model relates to a kind of low-speed diesel engine frame guide plate process unit.

Background technology

Frame is strength member in the marine low speed diesel engine, is Large Box class part, and size and weight are large, complex structure, and requirement on machining accuracy is high, need to utilize the large-sized numerical control process equipment, and all there is considerable influence quality, cost, the production cycle of complete machine.Frame guide plate face is the spigot surface that crosshad shoe slides up and down, because guide plate is thin, allowance is more, vibrates greatlyr, and the degree of depth is longer, and the processing of frame guide plate face is that key point also is difficult point.Therefore the efficient of guide plate processing directly affects the working (machining) efficiency of frame.At present for frame drive end fuel oil side and exhaust side, and the processing of frame free end fuel oil side and four locational guide plate faces of exhaust side is to carry out successively one by one, whenever finish the processing of a plate and namely need adjust the guide plate annex one time, this method working (machining) efficiency can't effectively improve.

Summary of the invention

The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of low-speed diesel engine frame guide plate process unit being provided, to improve working (machining) efficiency.

The utility model is that the technical solution problem adopts following technical scheme:

The utility model low-speed diesel engine frame guide plate process unit adopts dragon to mill Digit Control Machine Tool, is at platform portal frame to be set, and the Chief axis of lathe is installed on the portal frame crossbeam; Its design feature is: the guide plate accessories mill-head is installed in the lower end at the Chief axis of described lathe, is installed with left-handed cutterhead and dextrorotation cutterhead by joint chair respectively in the both sides of described guide plate accessories mill-head.

The method of the sharp processing of the utility model low-speed diesel engine frame guide plate is to carry out according to the following procedure:

A, frame are upright on platform, Chief axis drives the guide plate accessories mill-head and moves above the frame drive end, is installed in the roughing that left-handed cutterhead on the guide plate accessories mill-head and dextrorotation cutterhead are finished frame drive end fuel oil side and exhaust side guide plate face from top to bottom simultaneously;

B, Chief axis drive the guide plate accessories mill-head and move above the frame free end, horizontally rotate 180 °, be installed in free end fuel oil side that left-handed cutterhead on the guide plate accessories mill-head and dextrorotation cutterhead from top to bottom finish frame simultaneously and the roughing of exhaust side guide plate face.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model is installed respectively left-handed cutterhead and dextrorotation cutterhead in the both sides of guide plate accessories mill-head, processing when realizing frame fuel oil side and exhaust side guide plate face, thus greatly improved working (machining) efficiency.

2, the utility model is adding man-hour, and both sides are simultaneously stressed, and the process system rigidity is better, stable cutting.
