A Secondary Flywheel Pneumatic Balance Fixture with Automatic Centering Device

Abstract

The invention discloses a secondary flywheel pneumatic balance clamp with an automatic centering device. The secondary flywheel pneumatic balance clamp comprises a working base station, wherein a vertical gas-pressure telescopic pole is fixedly arranged above the working base station; a fixed tray is fixedly welded at the upper end of the telescopic end of the vertical gas-pressure telescopic pole; limiting rods are fixedly welded on the left side, the right side, the rear side and the front side inside the fixed tray; movable clamping plates are inserted into the limiting rods in a penetrating mode; slide wheels are fixedly connected below the movable clamping plates through connecting steel strips; and the slide wheels are in rolling fit to the inner bottom surface of the fixed tray. Thesecondary flywheel pneumatic balance clamp is simple and convenient in configuration in comparison with the existing advanced original factory instrument, can greatly reduce cost, is very suitable for equipping in a common car repair factory, has market prospect and competitiveness, can be suitable for clamping flywheels of different models, is higher in applicability and cost performance, avoidsmanual inaccurate positioning for a center of the flywheel, and greatly improves efficiency.

Description

technical field [0001] The invention relates to the field of flywheel positioning and clamping, in particular to a secondary flywheel pneumatic balancing clamp with an automatic centering device. Background technique [0002] In order to reduce the torsional vibration of the transmission system caused by the unbalanced rotation of the engine, a torsional damper is traditionally used in the clutch to achieve the purpose of vibration reduction. But on the one hand, the torsional damper cannot reduce the natural frequency of the entire power transmission system below the idle speed of the engine, so resonance still exists during the entire engine operation; on the other hand, due to the installation radius of the torsional damper spring To limit and transmit torque, it is difficult to reduce torsional vibration by reducing the spring stiffness in actual design. Vibration effect, the first mass-produced dual-mass flywheel in the history of automobiles was put into production ar...

Problems solved by technology

That is to say, in any case, the resonant speed is outside the speed range of engine operation, but this device still has some disadvantages in processing or testing: at present, there is no relatively simple fixing fixture that can effectively control it. Fix it, because it needs to be effectively fixed and clamped in some repairs, and there are no expensive original factory fixed precision instruments in ordinary car repair shops; the existing clamping fixture can only be used for certain fixed types of flywheels Fixed clamping cannot adapt to different types of flywheels; manual positioning of the flywheel center is not accurate enough, and the speed is relatively slow and the steps are cumbersome
