A surface cam adjustable constant force output mechanism

Abstract

The invention provides a curved surface cam adjustable constant force output mechanism. The mechanism is composed of a base assembly, a horizontal adjustment assembly, a horizontal restraint assembly, an output force assembly and a vertical auxiliary adjustment assembly; the base assembly is composed of a top cover and a sleeve body. It is composed of the flange cover and the parts are installed in sequence; the horizontal adjustment assembly consists of an outer sleeve, an inner sleeve, a roller mounting frame, a roller, a pin, a spring, a bottom plate and an adjustment screw, and all parts are connected in sequence; the horizontal restraint assembly consists of The driving piece, the mounting frame, the roller, the pin shaft and the roller mounting block are installed in sequence; the output force component is composed of a cam, and the cam is matched with the center hole of the top cover; the vertical auxiliary adjustment component is composed of a screw rod, a nut, a torsion spring and a vertical adjustment screw The cam is connected with the horizontal adjustment component, the horizontal restraint component and the vertical auxiliary adjustment component; the invention has the advantages of large bearing capacity, large adjustable constant force range, simple structure and high reliability.

Description

technical field [0001] The invention belongs to a constant force loading mechanism, and particularly provides a surface cam adjustable constant force output mechanism. Background technique [0002] The constant force mechanism is a device that can make the internal mechanism generate a certain displacement and output a constant force under the action of non-constant force input. At present, the constant force mechanism is 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 has broad application prospects and economic value. However, the current method of constant force output is mainly mechatronic control, which detects the size of the load through sensors arranged in the end effector, and forms a closed-loop system for dynamic control to achieve a relatively constant output force. However, mechatronics is generally complicated in st...

Problems solved by technology

However, the constant force output by this mechanism is constant, and cannot output adjustable constant force, so it is difficult to apply to complex actual engineering projects
