Description
Technical field
The present invention relates to tooling and fixture technical field, particularly it is a kind of can be used for six-cylinder engine crankshaft rod journal it is thick,
The fixture of finishing.
Background technology
Bent axle functional parameter：Bent axle is one of five big core parts for ensureing the external output characteristics of multi-cylinder engine, is led
Geometric accuracy parameter is wanted to include crank up central coaxial degree, same-phase rod journal concentricity, out of phase rod journal phase
To centre of gyration bounce, out of phase rod journal with respect to centre of gyration circumferential phase difference etc..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 is other than the general processing rule with axis class, also with its unique structure, technique
Feature mainly has complex-shaped, poor rigidity, technology to require high, and process answers specific aim to take corresponding measure.It is domestic at present
The multi-process assembly line that Crankshaft Machining is mostly formed using machine tool and special purpose machine tool, there are quality control, productions for manufacturing process
The problems such as efficiency, the degree of automation.Such as：(1) roughing process commonly uses multicut lather turning main bearing journal and rod journal,
Since the stability of process quality is affected by factors such as lathe, fixture, operation, detections, finished product accuracy needs to be ensured stay
There is larger allowance for finish；(2) finishing passes, it is complete on common crankshaft fixture using special crankshaft grinding machine (such as MQ8260)
Into corase grinding-half fine grinding-fine grinding-polishing, operator is needed in installation, adjustment, processing, detection process compared with high professional qualification, is seriously affected
The stability of processing efficiency and product quality.
Six-cylinder engine crankshaft industrial analysis：Six-cylinder engine crankshaft design feature：1) six rod journals are coaxial two-by-two,
Axial line and main bearing journal center parallel, and to press 120 ° of circle distributions on the basis of it；2) main bearing journal center and each company
Bar journal centre eccentricity is equal；3) in every place's rod journal Position Design counterweight, ensure crankshaft quality center and geometric center
It overlaps.
Rod journal processing is one of bottleneck technique for restricting Production of Crankshaft：
1) special fixture ensures that rod journal is coaxial two-by-two and coaxial with machining tool main shaft at six, and process is opposite
Main bearing journal eccentricity dimensional accuracy and the depth of parallelism are stablized；
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, ensures process fixture and workpiece total quality center and machine tool chief axis centre of gyration weight
It closes.
Invention content
The goal of the invention of the present invention is, in view of the above-mentioned problems, providing a kind of crankshaft-link rod diameter of axle processing tool system, uses
Mechanical, electrical, calculation overall-in-one control schema technology passes through the approach that design basis, technological datum, three base weight of detection benchmark are closed, once mounting
Whole rod journal processing are completed in positioning.Lathe, tooling, personnel are reduced to greatest extent to the influence degree of mismachining tolerance, are had
Effect improves the stability and processing efficiency of rod journal processing quality.
In order to achieve the above objectives, the technical solution adopted in the present invention is：
