Abstract
The invention relates to a six-degree-of-freedom vibration aging platform. The six-degree-of-freedom vibration aging platform comprises a vibration platform body, three groups of parallel crank, connecting rod and sliding block mechanisms and three control motors, wherein each parallel crank, connecting rod and sliding block mechanism comprises a crank, a connecting rod, a sliding block and a transmission connecting rod, the three cranks are respectively driven by one of the three control motors, the three control motors are fixed on a rack, and the motion of the three cranks are realized through programming. The vibration platform body can vibrate at six degrees of freedom through the three connecting rods, the three sliding blocks and the three transmission connecting rods, so that a workpiece to be processed can vibrate at multiple degrees of freedom, the modes of vibration of the workpiece to be processed in transverse direction and torsion are activated, and the problems that existing vibration at a single degree of freedom has a poor ageing treatment effect and much residual stress cannot be eliminated easily are solved.
Description
Technical field
The present invention relates to a kind of oscillating aging equipment in Machining Technology field, particularly a kind of six-degree of freedom vibration timeliness platform.
Background technology
It is a kind of conventional method of eliminating its inner residualinternal stress of engineering materials processing that oscillating aging is processed, by vibration, when making the internal stress of inside workpiece remnants and the vector of additional vibratory stress meet or exceed material yield intensity, make material that micro-viscous deformation occur, thereby make the internal stress of material internal be relaxed and alleviate.
Existing oscillating aging platform is to adopt vibrator, makes vibrator and workpiece produce certain resonance, reaches the object of oscillating aging.This oscillating aging platform is single degree of freedom, exciting in one direction, can not on the six degree of freedom of space, excite the resonance of each first order mode of workpiece, vibrating effect is very limited, especially for large-scale or baroque member, be difficult to eliminate its unrelieved stress, can not effectively reach the object of oscillating aging, this is the major reason that Vibration Aging Process fails to be used widely.
Summary of the invention
The object of this invention is to provide a kind of six-degree of freedom vibration timeliness platform, it can overcome the deficiency of existing oscillating aging platform single direction exciting, effectively excites each first order mode of workpiece, eliminates the unrelieved stress of workpiece, significantly improves the effect of oscillating aging.
The present invention achieves the above object by the following technical programs: a kind of six-degree of freedom vibration timeliness platform, involving vibrations platform, parallel crank linkage rod slide block mechanism and control motor, described shaking platform is circle or rectangular flat, described parallel crank linkage rod slide block mechanism is by kinematic link, slide block, connecting rod and crank form, described kinematic link one end is hinged on shaking platform by smooth ball hinge, the other end is hinged on slide block by smooth cylindrical hinge, slide block can slide up and down in vertical chute, vertical chute is fixed in frame, described connecting rod one end is hinged on slide block by smooth cylindrical hinge, the other end is hinged on crank by smooth cylindrical hinge, crank is connected to be controlled on motor, controlling motor is fixed in frame.
Shaking platform is driven by parallel crank linkage rod slide block mechanism and motor, and parallel crank linkage rod slide block mechanism and motor compose in parallel parallel institution in space, and parallel crank linkage rod slide block mechanism place plane is perpendicular to the line at interface point and platform center.
Described crank is by controlling electric machine control, by the motion of programming Control crank, pass through again connecting rod, slide block and connecting rod are controlled the vibration of shaking platform, parallel crank linkage rod slide block mechanism has three groups, respectively by three electric machine control, and vibration and the twisting vibration of controlled damping moving platform any direction, realize the vibration of shaking platform space six degree of freedom, effectively realize the oscillating aging of workpiece on shaking platform.
Outstanding advantages of the present invention is:
Due to the line of three groups of parallel crank linkage rod slide block mechanism place planes perpendicular to interface point and platform center, like this, platform not only can produce the transverse vibration of various directions, but also can produce twisting vibration, make processed workpiece on platform produce the multiple degree of freedom resonance of the various vibration shapes, effectively eliminate unrelieved stress, the oscillating aging that can be applicable to various workpiece is processed, comprise high rigidity, high natural frequency workpiece, as the oscillating aging of the workpiece such as roll, machine tool beam is processed.
