Problems solved by technology

At present, the detection method to control its angle is to use three coordinates or a terminal detection plane to detect it during the production process. The detection time is long and the efficiency is low. The average time is 5 to 7 minutes to detect whether the phase angle of the double-stage tower wheel is qualified.
In addition, in the production process, it is impossible to inspect the products produced in large quantities by using the three-coordinate or terminal inspection plane, so there are uncontrollable risks in the production

Abstract

The invention relates to the technical field of two-stage cone pulleys, and discloses a two-stage cone pulley phase angle error detecting device and a detecting method thereof. The device comprises ameasuring base, a two-stage cone pulley centering component, a pinion cogging positioning component and a large gear phase offset distance measuring component. The pinion cogging positioning componentis disposed at the pinion side of the two-stage cone pulley to be detected and radially positions the pinion cogging; the large gear phase offset distance measuring component is disposed on the largegear side of the two-stage cone pulley to measure the offset of the center position of a tooth socket being closet to the axis of the pinion cogging positioning component relative to the corresponding position of a two-stage cone pulley calibration component. The two-stage cone pulley phase angle error detecting device and the detecting method thereof employ the two-stage cone pulley centering component and the pinion cogging positioning component to locate the two-stage cone pulley to be detected to measure the deviation value to obtain an error value so as to greatly improve the detection efficiency of the two-stage cone pulley phase angle.

Description

technical field [0001] The invention relates to the technical field of double-stage tower wheels, in particular to a double-stage tower wheel phase angle error detection device and a detection method thereof. Background technique [0002] The overhead camshaft of the engine can shorten the distance between the camshaft and the valve, which omits the tappet and tappet of the valve, thus simplifying the transmission mechanism between the camshaft and the valve, making the engine compact and reducing the overall system cost. The quality of reciprocating motion improves the transmission efficiency and reduces the transmission noise under high-speed operation. Therefore, the application of overhead camshaft is more and more extensive. [0003] Although the overhead camshaft shortens the distance from the valve, it increases the distance between the camshaft and the crankshaft. Therefore, in order to shorten the transmission chain and reduce the moment of inertia, the applicatio...
