Description
Technical field
The utility model is that a kind of mechanical frock detects utensil, particularly relates to a kind of engine crankshaft and detects bracing or strutting arrangement.
Background technology
Engine crankshaft can be described as one of most important parts of engine, and it coordinates the power gas pressure acted on piston being become rotation with connecting rod, passes to the transmission mechanism on chassis.Meanwhile, valve actuating mechanism and other servicing unit is driven, as fan, water pump, generator etc.During work, bent axle bears gas pressure, the effect of inertia force and moment of inertia, stressed large and stressed complexity, and bears the percussion of stress alternation.Along with development and the strengthening of engine, the condition of work of bent axle is further harsh, its planform is complicated, size and overall engine size and weight closely bound up, Crankshaft Sizes size affects appearance and size and the weight of engine to a great extent, and it accurately measures to detect has great impact for engine performance.Engine crankshaft traditional is at present measured, use three coordinate measuring machine, in the majority with gantry-type three-coordinate measuring machine, when measuring machine detects the size of bent axle, need to carry out clamping to bent axle, the stable of bent axle is ensured when gantry-type three-coordinate measuring machine chaining pin is got ready in order to enable bent axle, do not affect the precision that Crankshaft Sizes is measured, typically use V-block to play main fixed support effect, or design special fixture and carry out clamping bent axle, when detecting, first two pieces of V-blocks are put in measuring machine marble platform, bent axle is positioned over detection V-block completing size, but there are the following problems for such detection mode:
1, bent axle is positioned over detection V-block completing size, when measure change next bent axle time, due to can V-block be rocked when putting bent axle, make so also to need when three coordinate measuring engine measurement again to get location ready, very time-consuming, is unable to catch up with the progress measured when number of packages;
2, when gantry-type three-coordinate measuring machine detects dissimilar bent axle, be designed with special fixture and carry out clamping bent axle, the bent axle of one type needs a whole set of fixture, the a whole set of frock clamp of corresponding quantity is just needed when bent axle has several types, produce or buy frock clamp cost just very high, and the dissimilar bent axle rolled off the production line on crankshaft production line enters accurate measurement room, bent axle be positioned over fixture carry out three-dimensional coordinates measurement machine testing time, need not stop to change corresponding fixture, so not only time-consuming but also require great effort, have impact on the progress of detection equally.
3, bent axle is the important component part of engine interior part, the high-precision requirement of its size, especially the precision on trunnion surface determines the performance of engine, engine crankshaft is under the high idling of high speed is dynamic, with connecting rod friction, if there is the defect such as decorative pattern, scuffing on main bearing journal surface, will the overall performance of engine be affected, and service life.And the steel grade that the material that the V-block playing fixed support uses is HT200 or other materials, when bent axle being put V-block and rotary crankshaft time, can friction be produced with V-block supporting surface, because main bearing journal is suitable with this type of V-block case hardness, and then produce decorative pattern, scuffing.
