Adjustable cam controller with mechanical limiting function

Abstract

The invention relates to an adjustable cam controller with a mechanical limiting function. The adjustable cam controller comprises a camshaft and a cam component which is arranged on the camshaft, wherein the cam component comprises a shaft sleeve, and an outer cam piece and an inner cam piece which are sleeved on the shaft sleeve; two side end faces of the inner cam piece are provided with gear rings; one side end face of the outer cam piece is provided with a gear ring; a side end face of the shaft sleeve is provided with a gear ring; the gear ring on one side end face of the inner cam piece is meshed with the gear ring on the end face of the shaft sleeve; the gear ring on the other side end face of the inner cam piece is meshed with the gear ring on the end face of the outer cam piece; the inner sides of the gear rings on the two end faces of the inner cam piece are provided with a first limiting device and a second limiting device; the inner side of the gear ring on the end face of the outer cam piece is provided with a third limiting device which can rotate in a range of less than 360 degrees relative to the first limiting device; and the inner side of the gear ring on the end face of the shaft sleeve is provided with a fourth limiting device which can rotate in a range of less than 360 degrees relative to the second limiting device. The inner and outer cam pieces only can be adjusted in the specified angle range.

Description

technical field [0001] The invention relates to an adjustable cam controller with a mechanical limit function, especially a cam controller used for automation equipment in iron and steel, metallurgy, machinery, light industry, mines and various automatic assembly lines, suitable for forging Mechanical or "mechanical-electrical" safety control systems for mechanical presses. Background technique [0002] The adjustable mechanical cam controller is an important part of the electrical control system in the "mechanical-electrical" safety control system of the mechanical press. In a working cycle of a mechanical press, the actions of each working mechanism of the main machine and the auxiliary machine (especially the auxiliary machine that controls the movement of the press slider) have a strict logical relationship, including the sequence of actions and the time taken by the actions. The method of dealing with the logical relationship of the working mechanism is usually to dist...
