[0041] Working principle: Place the workpiece to be processed, such as a metal sheet, on top of several support heads so that the lower surface of the metal sheet contacts the upper surface of the movable push rod of the support head. Due to the metal characteristics of the metal sheet itself, the surface of the sheet will be warped and uneven to a certain extent. The movable push rod of each support head moves downward for a distance or does not move under the action of the metal sheet. After the movable push rods of each support head are stable, a support surface consistent with the undulation of its lower surface can be determined for the metal sheet placed above it. At this time, push the movable block of each support head upward, and the movable block drives the movable sleeve above it to move upward. The inner cone surface of the movable sleeve moves up and acts on the outer cone surface of the clamping sleeve. The clamping sleeve is squeezed and contracted, clamping the movable push rod and limiting the movement of the movable push rod, so that the movable push rods of the support heads are all in a fixed state, thereby providing stable support for the workpiece placed above it that fits the lower surface of the workpiece, which is convenient for milling and other processing operations on the sheet.

When it moves to a suitable position, the movable sleeve is driven to move up through the movable block, and the inner cone surface of the movable sleeve moves up to act on the outer cone surface of the clamping sleeve. The clamping sleeve is squeezed and contracted, clamping the movable ejector rod, limiting the movement of the movable ejector rod, and playing the role of fixed support. The downward movement distance of the movable ejector rod depends entirely on the action force of the workpiece, that is, the downward movement distance of the movable ejector rod is continuously adjustable, which can be suitable for workpieces in different situations. When multiple support heads are used in combination to support the workpiece, the downward movement distance of the movable ejector rod of each support head varies according to the different curvature degrees of the lower surface of the workpiece. Therefore, it is possible to support the workpiece with a curved lower surface and maintain the natural curvature of the workpiece. The structure is ingenious and the operation is simple.

[0043] In addition, it adopts a clamping sleeve to replace the steel ball clamping mechanism in the original scheme, which has a simple structure and eliminates the processing process of installing steel balls, greatly improving the processing efficiency of the support head; in addition, through the setting of the first wire groove and the second wire groove, and the first wire groove extends to the second jacket without cutting the second jacket, similarly, the second wire groove extends to the first jacket without cutting, thereby enhancing the contraction force of the clamping sleeve and the stability of the structure, so that the stability of the clamping sleeve clamping the movable push rod can be ensured, thereby ensuring the stable support of the push rod to the workpiece; in addition, the setting of the arc surface or spherical surface makes the support for the workpiece a point contact support, thereby ensuring the accuracy of the support, and in addition, the protrusion is embedded in the spring, which plays a certain limiting role on the spring, thereby preventing the spring from deviating and affecting the rebound support force and the support accuracy.
