Abstract
The utility model relates to a crankshaft flywheel positioning device, which is mainly used for installing and positioning flywheels at two ends of a crankshaft. The crankshaft flywheel positioning device comprises a positioning platform and three sets of identical crankshaft V-shaped roller supports which are arranged on the positioning platform side by side, each crankshaft V-shaped roller support comprises a support body and two rollers which are symmetrically disposed above the support body, a supporting seat is further fixed on the positioning platform, and the support bodies are connected with the supporting seat via adjusting bolts. The crankshaft flywheel positioning device is used for installing and positioning the flywheels at the two ends of the crankshaft, is simple in structure, can conveniently complete measurement of axial and radial circular runout tolerances of end surfaces of the flywheels after the crankshaft and the flywheels are in butt joint via non-articulated bolts, is high in measurement precision and fast in detection speed, and can be directly used in fields. Operators can finally guarantee concentricity of the crankshaft and the flywheels by means of adjusting the non-articulated bolts according to the circular runout tolerances measured by a dial indicator.
Description
Technical field
The utility model relates to a kind of crankshaft-flywheel positioner, is mainly used in the installation location of crankshaft two end flywheel.
Background technology
Bent axle is one of key components and parts of diesel engine, and bent axle mainly is the rectilinear motion that the fuel oil blast produces to be changed into rotatablely move, and power output; This outer crankshaft still drives the parts of systems such as valve actuating mechanism, fuel oil, lubricated, cooling, speed governing.The flywheel of diesel engine mainly is the effect of playing storage power and balance.Flywheel is to be installed in crankshaft two end by non-articulation bolt and articulation bolt.When flywheel is installed, in order to guarantee the balance of bent axle and flywheel integral body, prevent to produce centrifugal force, two parts just must be coaxial so, guarantees can change down assembly process over to one after the axiality.Before diesel engine assembling was ground watt, the articulation positioning bolt hole that bent axle is connected with flywheel must be processed at the boring machine of assembly shop.In order to guarantee assembly precision, before the articulation positioning bolt hole that the bent axle that drills and reams is connected with flywheel, should finish the measurement of the axial and radial run-out tolerance of the non-articulation bolt butt joint of bent axle and flywheel rear flywheel end face, and then could guarantee that when assembling round run-out tolerance of flywheel seam is qualified, checks but also there is related device can finish the crankshaft-flywheel location now.
Summary of the invention
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and be used for the installation location of crankshaft two end flywheel and can guarantee bent axle and the crankshaft-flywheel positioner of the whole axiality of flywheel.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of crankshaft-flywheel positioner, it is characterized in that: comprise locating platform and three groups of identical bent axle V-arrangement rolling wheel supports that are arranged side by side on locating platform, bent axle V-arrangement rolling wheel support comprises support body and is symmetricly set on two rollers of support body top, also be fixed with supporting seat on the locating platform, support body is connected with supporting seat by regulating bolt.
Operation principle and process:
During use, at first bent axle is supported on three bent axle V-arrangement rolling wheel supports, after regulating bolt adjusting centering, make bent axle be positioned at horizontal direction, flywheel is connected crankshaft two end with non-articulation bolt, use dial gauge (band magnetic force gauge stand) to detect the axial and radial run-out tolerance (the same prior art of detection method) of flywheel end face then, if it is defective, can regulate non-articulation bolt, in the scope of circle run-out tolerance in specification requirement, it is coaxial to be that bent axle and flywheel have kept, at last tight non-articulation bolt, can change the processing that boring machine carries out bent axle and flywheel align reaming positioning bolt hole over to.
The application of crankshaft-flywheel positioner, measurement by the axial and radial run-out tolerance that can finish the flywheel end face after the non-articulation bolt of bent axle and flywheel docks easily, its certainty of measurement height, detection speed is fast, can directly use at the scene, the size of the round run-out tolerance that the operator can measure according to dial gauge is by regulating non-articulation bolt, the final axiality that guarantees bent axle and flywheel is used when this crankshaft-flywheel positioner can be used for each type crankshaft of diesel engine flywheel align reaming.In addition,, whole crankshaft-flywheel positioner can be installed near the boring machine of machined workshop section of assembly shop, change the processing of boring machine operation thereby be convenient to measure the flywheel seam back of beating for easy to use.
The beneficial effect that the utility model had is: a kind of crankshaft-flywheel positioner is provided, the installation location that is used for the crankshaft two end flywheel, simple in structure and can finish easily flywheel end face after the non-articulation bolt butt joint of bent axle and flywheel axially and the measurement of radial run-out tolerance, its certainty of measurement height, detection speed is fast, can directly use at the scene, the size of the round run-out tolerance that the operator can measure according to dial gauge, by regulating non-articulation bolt, finally guarantee the axiality of bent axle and flywheel.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Shown in Fig. 1～4, the crankshaft-flywheel positioner comprises locating platform 1 and three groups of identical bent axle V-arrangement rolling wheel supports 4 that are arranged side by side on locating platform 1, bent axle V-arrangement rolling wheel support 4 comprises support body 5 and is symmetricly set on two rollers 6 of support body 5 tops, also be fixed with supporting seat 2 on the locating platform 1, support body 5 is connected with supporting seat 2 by regulating bolt 3.
Operation principle and process:
During use, at first bent axle is supported on three bent axle V-arrangement rolling wheel supports 4, after regulating bolt 3 adjusting centerings, make bent axle be positioned at horizontal direction, flywheel is connected crankshaft two end with non-articulation bolt, use dial gauge (band magnetic force gauge stand) to detect the axial and radial run-out tolerance (the same prior art of detection method) of flywheel end face then, if it is defective, can regulate non-articulation bolt, in the scope of circle run-out tolerance in specification requirement, it is coaxial to be that bent axle and flywheel have kept, at last tight non-articulation bolt, can change the processing that boring machine carries out bent axle and flywheel align reaming positioning bolt hole over to.
The application of crankshaft-flywheel positioner, measurement by the axial and radial run-out tolerance that can finish the flywheel end face after the non-articulation bolt of bent axle and flywheel docks easily, its certainty of measurement height, detection speed is fast, can directly use at the scene, the size of the round run-out tolerance that the operator can measure according to dial gauge is by regulating non-articulation bolt, the final axiality that guarantees bent axle and flywheel is used when this crankshaft-flywheel positioner can be used for each type crankshaft of diesel engine flywheel align reaming.In addition,, whole crankshaft-flywheel positioner can be installed near the boring machine of machined workshop section of assembly shop, change the processing of boring machine operation thereby be convenient to measure the flywheel seam back of beating for easy to use.
