Abstract

The invention provides an adjustable constant force output mechanism with a curved cam. The mechanism is composed of a base assembly, a horizontal adjusting assembly, a horizontal restraining assembly, an output force assembly and a vertical auxiliary adjusting assembly; the base assembly is composed of a top cover, a sleeve body and a flange cover, and the parts are sequentially installed; the horizontal adjusting assembly is composed of an outer sleeve, an inner sleeve, a roller installation frame, a roller, a pin shaft, a spring, a bottom plate and an adjusting screw, and all the parts are sequentially connected; the horizontal restraining assembly is composed of a driving piece, an installation frame, a roller, a pin shaft and a roller installation block, and all the parts are sequentially installed; the output force assembly is composed of the cam, and the cam is matched with a center hole of the top cover; the vertical auxiliary adjusting assembly is composed of a lead screw, a nut, a torsional spring and a vertical adjusting screw, and all the parts are sequentially and fixedly connected; and the cam is connected with the horizontal adjusting assembly, the horizontal restraining assembly and the vertical auxiliary adjusting assembly. The adjustable constant force output mechanism has the beneficial effects of being large in bearing capacity, large in adjustable constant force range, simple in structure and high in reliability.

Description

technical field [0001] The invention belongs to a constant force loading mechanism, and in particular provides an adjustable constant force output mechanism with a curved surface cam. Background technique [0002] The constant force mechanism is a device that can produce a certain displacement of the internal mechanism and output a constant force under the action of a non-constant force input. At present, constant force mechanisms are widely used in the fields of mechanical automation, electrical automation, aviation equipment and instrumentation, especially in the fields of mechanical processing and electrical control, which have broad application prospects and economic value. However, the current constant force output method is mainly mechatronic control, which detects the load size through the sensor arranged on the end effector, and forms a closed-loop system for dynamic control to achieve a relatively constant output force. However, mechatronics generally has complex s...
