Intelligent control flexible rack

Abstract

The invention discloses an intelligent control flexible rack. The intelligent control flexible rack comprises a base, wherein a support and a workpiece support are arranged on the base; the support isconnected with a cross beam through a rotating shaft, and a balance device is arranged at one end of the cross beam, and an operation mechanism is arranged at the other end of the cross beam; the balance device comprises tension springs, one ends of the tension springs are fixed on the cross beam, the other ends of the tension springs are connected with piston rings, and the piston rings are in sliding connection with a strip-shaped groove in a driving arm through pull rods; the end part of the driving arm is fixed to a driving wheel, and the driving wheel is meshed with a motor output wheel;the driving wheel and a motor are arranged on the support; an encoder is fixed on the driving wheel; and a motor controller is connected with a PLC, and the encoder is connected with the PLC. The intelligent control flexible rack has the advantages that the operation structure is a motor-driven tension adjusting structure, the PLC judges the rotation angle of the driving wheel according to signals transmitted by the encoder, and then the tension of the spring is calculated and proportioned to the gravity on the right side so as to realize the adjustment of the downward pressure on the right side.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a flexible balance frame, which can be widely used in various mechanical equipment. Background technique [0002] Existing racks are generally of rigid structure. When in use, if flexible processing is required, special flexible devices are often required; for example, the polishing machine is generally a cloth wheel polishing machine, which uses a motor to drive the cloth wheel to rotate, and the worker holds the workpiece and the cloth. Wheel contact is used for polishing; for larger workpieces, on the contrary, the workpiece is polished by a hand-held small polishing machine; this polishing method is not only completely controlled by the operator, but also cannot guarantee the accuracy of the operation; in addition, injuries often occur. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide an intelligently...
