Description
Technical field
The present invention relates to technical field of tooling clamps, particularly one can be used for six-cylinder engine crankshaft rod journal thick,
The fixture of polish.
Background technology
Bent axle functional parameter: one of bent axle five big core parts being to ensure that the external output characteristics of multi-cylinder engine, it is main
Geometric accuracy parameter is wanted to include crank up central coaxial degree, same phase rod journal axiality, out of phase rod journal phase
Beat the centre of gyration, out of phase rod journal is poor relative to centre of gyration circumferential phase.Bent axle and cylinder body, connecting rod, piston
The gas pressure that internal combustion is formed is transformed into rotary power output by composition slider-crank mechanism.
State of art: Production of Crankshaft, in addition to the general processing rule with axle class, also has the structure of its uniqueness, technique
Feature, mainly has complex-shaped, poor rigidity, technology to require high, and the course of processing answers specific aim to take corresponding measure.The most domestic
Crankshaft Machining many employings machine tool and the multiple operation streamline of special purpose machine tool composition, there is quality control, production in manufacture process
The problem such as efficiency, automaticity.As: (1) roughing process, conventional multicut lather turning main bearing journal and rod journal,
Due to process quality stability by lathe, fixture, operate, the factor such as detection is affected relatively big, finished product accuracy to be ensured needs to stay
There is bigger allowance for finish；(2) finishing passes, uses special crankshaft grinding machine (such as MQ8260) complete on common crankshaft fixture
Become corase grind-half fine grinding-fine grinding-polishing, operator installing, adjust, process, detection process needs relatively high professional qualification, have a strong impact on
Working (machining) efficiency and the stability of product quality.
Six-cylinder engine crankshaft industrial analysis: six-cylinder engine crankshaft construction features: 1) six rod journals are coaxial two-by-two,
Axial line and main bearing journal center parallel, and by 120 ° of circle distribution on the basis of it；2) main bearing journal center and each company
Bar journal centre eccentric throw is equal；3) rod journal Position Design counterweight is often being located, it is ensured that crankshaft quality center and geometric center
Overlap.
Rod journal processing is one of bottleneck technique of restriction Production of Crankshaft:
1) special fixture ensures that at six, rod journal is coaxial and coaxial with machining tool main shaft two-by-two, and the course of processing is relative
Main bearing journal eccentric throw dimensional accuracy and the depth of parallelism are stable；
2) can be on the basis of crank spindle line, circumference precisely indexes 120 °, and once mounting completes rod journal processing at six；
3) fixture carries counterweight, it is ensured that course of processing fixture and workpiece total quality center and machine tool chief axis centre of gyration weight
Close.
Summary of the invention
The goal of the invention of the present invention is, for the problems referred to above, it is provided that a kind of crankshaft-link rod diameter of axle processing tool system, uses
Mechanical, electrical, calculation overall-in-one control schema technology, the approach closed by design basis, technological datum, detection benchmark three basic weight, once mounting
Location, completes the processing of whole rod journal.Reduce lathe, frock, personnel's influence degree to mismachining tolerance to greatest extent, have
Effect improves stability and the working (machining) efficiency of rod journal crudy.
For reaching above-mentioned purpose, the technical solution adopted in the present invention is:
