The working principle is as follows: the metal plate to be processed is placed above the plurality of supporting devices, the lower surface of the metal plate is in contact with the upper surfaces of the movable columns of the supporting devices, the surface of the metal plate is warped but not flat due to the metal characteristics of the metal plate, the movable column of each supporting device moves downwards for a certain distance or does not move under the action of the metal plate, after the movable column of each supporting device is stabilized, a supporting surface which is consistent with the fluctuation of the lower surface of the metal plate above the supporting device can be determined, at the moment, the push block of each supporting device is pushed upwards, the push block drives the elastic component above the push block to upwards push the movable sleeve to upwards move, the movable sleeve upwards moves to upwards move steel balls which are in contact with the inner wall of the movable sleeve, so that the fixed sleeve tightly holds the movable column, the up-and-down movement of the movable column is limited, and the movable columns of the supporting devices are all in a fixed state, therefore, the support which is stable and is matched with the lower surface of the plate material is provided for the plate material arranged above the support, and the processing operations such as milling and flattening of the plate material are facilitated.
When the CNC processing device for the electronic equipment parts is adopted, the movable column can adjust the downward moving distance according to the bending degree of the plate to be processed placed on the movable column through the free movement of the movable column in the vertical direction, so that the plate to be processed can be accurately supported under the condition of keeping the self bending state, the clamping and fixing of the movable column are realized through the matching of the pushing block and the movable sleeve, the steel balls and the fixed sleeve, the support of the plate to be processed is stable and reliable, the plate is stably and reliably supported by combining at least three floating support components, a support surface is provided for the plate, the support surface is matched with the bending degree of the plate, the plate is stably supported under the most natural state, an accurate plane can be obtained only by milling the plate once, and then the surface processing can be carried out on the plate under the support of the plane support jig, the whole processing of the plate can be completed only by turning over once, so that the processing procedure is greatly saved, the production efficiency and precision are improved, the material consumption of the plate is greatly reduced, the waste of the raw material is reduced, the cost is saved, and the product efficiency is improved;
secondly, the reset spring is arranged, so that after the thrust force applied to the push block is removed, a downward acting force is applied to the movable sleeve, the movable sleeve moves downwards, the steel balls in the containing cavity can be driven to roll downwards, the steel balls roll downwards and return to the initial state, the movable column is loosened by the fixed sleeve, the movable column returns to move up and down, the effect of automatically returning to the initial state is achieved through a simple structural design, each component returns to the initial state without adding a downward pulling force, the structure is ingenious, and the use is convenient;
thirdly, the baffle and the first flange are arranged to respectively block the upper part and the lower part of the cavity to prevent the steel balls in the cavity from jumping out, so that the stability of the whole structure is ensured, the second flange is arranged to play a good supporting role on the upper structures such as the fixed sleeve and the like, the upper structure is prevented from being loosened to influence the stability and the precision of the whole structure, the two limiting columns are matched with the second flange to limit the upward moving distance of the movable sleeve, and the phenomenon that the steel balls are pushed out by greatly pushing the movable sleeve due to overlarge stress of the push block to damage the whole structure can be effectively prevented; thirdly, the setting of its activity post internal spring, both can be when the activity post is pressed down by treating processing panel, provide a flexible reaction force to panel, play the effect of protection panel, can be after panel processing is accomplished again, provide a reaction force that recovers, make the activity post automatic recovery to initial position, and need not artifical the reset just can carry out next use, furthermore, encapsulate the spring in the outer sleeve, both can protect the spring, play good limiting displacement to the circumference of spring again, avoid the spring to appear the circumstances such as deformation and influence the use, again through the setting of double-screw bolt lower part embedding support column, play limiting displacement to activity post whole in circumference, guarantee that the activity post can only move on vertical direction, prevent that the activity post from taking place the skew and influencing the holistic precision of device.
