Description

Detection device for tappet of diesel engine part Technical Field The invention relates to the technical field of diesel engine part detection, in particular to a detection device for a tappet of a diesel engine part. Background The tappet rod of the diesel engine part is a key transmission component in a valve actuating mechanism of the diesel engine, is a slender cylindrical part, is arranged between a cam shaft and a rocker arm, and has the main effects of accurately transmitting reciprocating motion generated by a cam profile in the rotation process of the cam shaft to the rocker arm so as to push a valve to be opened, and realizing timing control of air intake and exhaust processes. In the prior tappet detection device, a plurality of dial gauges are usually relied on to work cooperatively in the cylindricity measurement process, and the shape error of the tappet detection device is evaluated by collecting multipoint data on the outer circle surface of the tappet, however, in the current mainstream detection device, most of the dial gauges only have the adjustment capability in the height direction, lack flexible displacement and layout adjustment functions in the horizontal direction, and when facing the tappet with different length dimensions, the transverse position of the dial gauges is fixed, so that the transverse distribution of the measurement points cannot be quickly adjusted according to the length change of a workpiece, thereby causing the same device to be difficult to adapt to tappet products with various specifications.
