The actuator rod of the under test turbocharger is located When placing above the hole, adjust the height of the turbocharger actuator to be tested by starting the lifting servo motor 202, and at the same time adjust the position of the turbocharger to be tested in the horizontal direction, so that the actuator rod is just in the placement hole 507. The pneumatic servo valve injects compressed air into the actuator cavity, and the actuator rod expands outward as the pressure increases. The falling height of the measuring plate 504 is measured by the distance sensor 506, which is the elongation of the actuator rod. Normal length is the standard, and abnormal elongation is non-standard.
[0035] Based on the above, the present invention is simple in structure and in terms of operation. By setting the horizontal sliding mechanism and the longitudinal sliding mechanism, the relative position of the measuring bracket and the clamping mechanism in the horizontal direction can be changed, and the device can be applied to turbines whose actuator rod is not straight. The detection of the supercharger actuator can be used to detect different types of turbocharger actuators by setting the lifting mechanism and the clamping mechanism, which has good applicability. At the same time, the setting of the buffer mechanism can clamp the turbocharger actuator conveniently Perform testing.
