A motorcycle engine pneumatic clamping device for dynamometer

Abstract

The invention discloses a pneumatic fixture for use in power measurement of motorcycle engines. A fixing plate (4) is provided with two first positioning pins (5) penetrating the fixing plate (4), with one pin located above the other; a moving plate (6) is disposed on the left of a vertical plate (3); the front end of the moving plate (6) is provided with two second positioning pins (7); a back plate (8) is disposed at the rear of the upper end of the vertical plate (3); a cylinder (9) is fixed to two rib plates (8a) parallel to each other in a penetrating manner; a cross beam (A) is disposed above the vertical plate (3); the cross section of the cross beam (A) is L shaped; a positioning post (C) is disposed at one end of the top of the cross beam (A); the positioning post (C) is perpendicular to the cross beam (A). The pneumatic fixture is ingenious in design and easy to implement, is good for arrangement of electrical components for testing, helps ensure positioning reliability of the engines, allows the performance of each engine to be more accurately tested and is higher in testing efficiency; the cylinder for power supply is firmly mounted on the back plate and is convenient to demount and mount, and the mounting position of the cylinder is easy to adjust.

Description

technical field [0001] The invention belongs to the technical field of motorcycle engines, and in particular relates to a mechanism for measuring the dynamometer of motorcycle engines. Background technique [0002] After the motorcycle engine is assembled, it needs to be tested on the bench to verify whether the performance of the engine meets the requirements. The existing engine performance test bench is not only complex in structure and takes up a lot of space, but also the operation of installing the engine on the bench is very cumbersome, time-consuming and laborious, and the labor intensity of workers is high, which will greatly affect the efficiency of the test. At the same time, the reliability of the positioning of the engine on the bench is poor, which will cause the test results to be inconsistent with the real situation, so that the consistent production of the engine is difficult to meet the requirements.
