Abstract

The invention discloses a clamping mechanism for general gasoline engine testing. The clamping mechanism comprises a base, a positioning clamping cylinder which is fixed on the base with a first mounting plate and a guiding track which is arranged on the base. A driving clamping cylinder which corresponds to the positioning clamping cylinder is arranged on a second mounting plate. A horizontal mounting plate is perpendicularly fixed with the second mounting plate and is arranged on the guiding track of the base. One end of the horizontal mounting plate away from the positioning clamping cylinder is connected with one end of a chain and the chain wraps around a chain wheel. The other end of the chain is connected with one end of the horizontal mounting plate next to the positioning clamping cylinder and the chain wheel is connected with an output shaft of a stepping motor. The smooth running of the driving clamping cylinder at a constant speed can be achieved by setting specified parameters to the stepping motor, so that huge impact caused by clamping on general gasoline engines can be avoided. Additionally, the chain and the chain wheel can be driven by the stepping motor to achieve fine-tuned clamping after the driving clamping cylinder contacts to the general gasoline engines.

Description

technical field [0001] The invention relates to general machine technology, in particular to a clamping mechanism for general machine testing. Background technique [0002] In order to ensure that the small general-purpose gasoline engine has excellent performance in all aspects, it is usually necessary to test the performance of the small general-purpose gasoline engine in all aspects before leaving the factory. The main detection parameters of the small general-purpose gasoline engine are detection of power value, rotational speed, emission value and fuel consumption value. The equipment used for the above detection mainly includes a workbench and an electrical console. The workbench is equipped with a clamping mechanism, a speed testing mechanism, and a gasoline engine parameter detection mechanism. At present, the clamping mechanism on the workbench is generally clamped by the action of the cylinder, which cannot realize fine-tuning during clamping, and because there ...
