Description
Technical field
The present invention relates to a kind of detection methods, are examined more particularly, to a kind of turbocharging shell and bonnet assemblies postwelding angle
Survey device and detection method.
Background technology
Due to being limited by air capacity in sucking cylinder, generated maximum power can be also restricted engine,
When the runnability of engine cannot be promoted further, can only be entered by compressing more air to increase output power
Cylinder increases fuel quantity to improve burning capacity for work, to increase the output power of engine.In current technology condition
Under, turbocharger is the only mechanical device that engine can be made to increase output power in the case where working efficiency is constant.Whirlpool
Wheel booster is to drive compressor impeller high speed rotation using the exhaust gas of engine discharge, and supply after compresses fresh air is started
Machine reaches the optimum state of burning.It not only increases the dynamic property of engine, and can efficiently reduce having in discharge exhaust gas
Evil composition, reduces noise, has energy saving and environmentally friendly double dominant.
Currently, turbocharger has been spread on the automobile of many types, especially obtained in automobile repacking fully
Using.It compensates for the inadequate natural endowment of some NA engines, makes engine in the feelings for not changing cylinder capacity
10% or more output power can be improved under condition, therefore many auto makers are all started using this supercharging technology to improve
The output power of machine uses the high performance for realizing car.
The design of turbocharger is related to multiple subjects such as aerodynamics, hydrodynamics, and surface modeling is complicated, to system
Making level of processing has higher requirement, wherein the control to turbocharger housing and bonnet assemblies postwelding angle requires just very
Height, therefore need to test to it according to testing requirements in postwelding.It is conventional generally within 3 degree due to the angle value very little
Detection means cannot reach required precision, to be usually detected by three-coordinates measuring machine.However, this needs to purchase three seats
Mark measuring instrument is simultaneously equipped with specialized operations personnel, not only increases the cost of investment of enterprise, and three-coordinates measuring machine is complicated for operation.
Number of patent application CN201320157506.4 discloses a kind of turbocharger exhaust gas by-pass valve valve rod rocking arm welding
Angle detects auxiliary device, which has main body, and the back side of main body is as reference plane, the right side of the front upper of main body
Edge is equipped with upper fixture block outstanding forward, and upper fixture block is equipped with the U-lag that Open Side Down, the left side edge of the positive lower part of main body
Equipped with lower fixture block outstanding forward, lower fixture block is equipped with the V-shaped groove that Open Side Down, passes through U-lag center line and V-shaped groove center line
Plane and main body frontoparallel.U-lag on the upper fixture block of the utility model blocks the axle sleeve of turbine case, the V on lower fixture block
Slot is stuck on pin, parallel with the main body back side with the plane of V-shaped groove center line by U-lag center line, in this way can be by valve rod
The back side that the line at the pin center on external part center and rocking arm is transferred to main body is detected in reference plane, using common omnipotent
The measurement of rocking arm soldering angle can be realized in bevel protractor.However, the utility model needs U-lag blocking the axle sleeve of turbine case simultaneously
V slots are stuck on pin, are not suitable for the measurement of turbocharging shell and bonnet assemblies postwelding angle.
