Description

technical field [0001] The invention relates to a torque detection device, in particular to a detection device for detecting the anti-torque performance of a processed combined camshaft. Background technique [0002] The traditional structure of the camshaft of an automobile engine is an integral casting structure, which is complex in processing, low in production efficiency, low in product qualification rate, high in energy consumption, and high in pollution. In recent years, combined camshafts have been commonly used in foreign engine industries. The advantages are: the processing process is environmentally friendly, the processing cycle is short, and the technical performance of engines using combined camshafts is more advanced. Since the combined camshaft is assembled by an interference fit between a set of cam plates and the mandrel, the bonding force between the cam plates and the mandrel must be tested to meet the design requirements. Foreign countries such as Krupp r...

Problems solved by technology

At present, the domestic processing technology is relatively extensive, and the detection torque is applied by manpower with a torque wrench. The operation is time-consuming, laborious, inefficient, and poor in reliability. It is only suitable for single-piece and small-batch production.
