A fixture for dynamometer

Abstract

The invention discloses a clamp for measuring power. A bottom plate (2) is connected with a base plate (10) by a bolt; the upper plate surface of the bottom plate (2) is provided with two rubber blocks (P) which are arrayed in parallel from left to right; upper and lower first positioning pins (5) are arranged on a fixed plate (4) in a penetrating manner; a movable plate (6) is arranged on the left side of a vertical plate (3); two second positioning pins (7) are arranged at the front end of the movable plate (6); a piston rod of an air cylinder (9) leftwards stretches out and is connected with the rear end of the movable plate (6); a transverse beam (A) is arranged above the vertical plate (3) and the cross section of the transverse beam (A) is L-shaped; a positioning column (C) is arranged at one end of the top of the transverse beam (A); the positioning column (C) is vertical to the transverse beam (A). The clamp for measuring the power has an ingenious design and is easy to carry out; an engine can be positioned reliably; the rubber blocks are arranged on the bottom plate in parallel so that the engine can be effectively prevented from falling off and being damaged; the air cylinder for providing the power is firm to mount on a backboard and convenient to detach and mount.

Description

technical field [0001] The invention belongs to the technical field of motorcycle engines, and in particular relates to a test fixture for 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. Contents of the invention [0003] The technical problem to be solved by the pre...
