Description

Adjustable divider mechanism

Technical Field

The utility model relates to a technical field is cut apart to the cam, especially relates to a regulation formula decollator mechanism.

Background

The cam indexer is also called as a cam indexer in engineering and is an intermittent indexer. It is a high-precision rotating device. When the force input shaft rotates, the cam roller rotates the force output turret according to a given displacement curve, and simultaneously rolls along the inclined surface of the rib. In the region of the rib in equilibrium with the end face of the cam, i.e. in the static range, the roller engages its shaft, but the power turret itself does not rotate. The tapered support ribs are typically in contact with two or three cam rollers so that rotation of the input shaft is evenly transmitted to the output shaft.

The presence of a non-smooth condition between the cam surface of the tapered support rib and the cam roller can damage the divider. The phenomenon of unsmooth rotation can be eliminated by adjusting the distance between the shafts. The spring zone of the cam roller and cam can be accessed by adjusting the preload to stiffen the divider. The structure and function of the cam roller are the best performance of the combination of the force turret and the cam roller, and high-speed operation can be realized. The existing cam graduator has no shockproof function and poor working stability.
