Engine net torque detection fixture

Abstract

An engine net torque detecting equipment comprises an adapter front section and an adapter rear section which are respectively arranged at two sides of an adapter middle section being in a pipe structure, three sections are fixed together and the axes are coincident, the inner wall of the adapter front section, being in a pipe structure, is adapted with an oil pump installation stage on an engine crankshaft, and the adapter rear section is sleeved on a positioning post at end part of a constant torque wrench, and the axis of the adapter rear section is perpendicular to the axis of the constant torque wrench. The invention, having the characteristics of artistic design, convenient execution, simple operation, and the like, is capable of quickly, accurately performing test to net torque of the engine, thereby guaranteeing the assembly quality of the engine, preventing repeated labor caused by repeated assembly and disassembly, reducing labor intensity of workers greatly, and improving assembly efficiency of the engine effectively.

Description

technical field [0001] The invention relates to a tooling fixture, in particular to an engine net torque detection tool to accurately detect whether the engine net torque meets requirements. Background technique [0002] In the assembly process of the automobile engine, in accordance with the requirements of relevant industry standards, it is necessary to detect the net torque of the crankshaft in three stages: after the crankshaft is installed, after the connecting rod and piston assembly is installed, and after the whole machine is assembled, so as to judge the movement of the engine. Whether the size of the frictional resistance between the pairs is up to standard. The traditional detection method is carried out by workers manually rotating the crankshaft. The workers judge by hand feel and assembly experience. Since there is no quantitative standard, the accuracy of this detection method is poor, so that the friction resistance between the engine motion pairs does not me...

AI Technical Summary

Problems solved by technology

The traditional detection method is carried out by workers manually rotating the crankshaft. The workers judge by hand feel and assembly experience. Since there is no quantitative standard, the accuracy of this detection method is poor, so that the friction resistance between the engine motion pairs does not meet the standard. Can pass the test, resulting in a decrease in engine power and torque, an increase in fuel consumption, and an increase in exhaust temperature

What's more, the engine cannot be started normally, and must be disassembled and reassembled, which leads to duplication of labor for workers, increased labor intensity of workers, and low assembly efficiency
