s1, a workpiece is firstly placed on a supporting plate (504) in a supporting piece (5), then an adjusting motor (301) is used for driving an adjusting rod (302) to rotate, a threaded area (303) on the adjusting rod (302) is used for driving a driving clamping plate (306) on a driving block (305) to move, so that the two driving clamping plates (306) are close to each other, two ends of the workpiece are respectively placed between the two corresponding clamping blocks (404), then a worm area (304) on the adjusting rod (302) drives a screw rod (502) to rotate through a worm wheel (501) along with the rotation of the adjusting rod (302), the screw rod (502) drives the supporting plate (504) to move downwards through a threaded cylinder (503) in cooperation with the guiding of a second telescopic rod (505), and the supporting plate (504) is separated from the workpiece;
s2, driving a bidirectional screw rod (402) to rotate through a servo motor (401), wherein the bidirectional screw rod (402) drives two moving blocks (403) to be close to each other, and the two moving blocks (403) drive corresponding clamping blocks (404) to clamp a workpiece, so that the workpiece is positioned at the center of the two moving blocks (403); simultaneously, the two moving blocks (403) drive the plate body (4072) to move through the two first telescopic rods (4071), so that the rotating plate (4074) on the plate body (4072) is attached to the outer wall of the workpiece, and the length of the workpiece can be measured through the first sensing probes (4075) in the two rotating plates (4074), wherein the length is the distance between the two first sensing probes (4075);
s3, driving a horizontal screw rod (601) to rotate through a horizontal motor (6), driving a horizontal screw block (602) to horizontally move by the horizontal screw rod (601) so that a mounting plate (606) on the horizontal screw rod moves to the upper part of a workpiece, and then driving the mounting plate (606) through an electric push rod (605) so that a measurer on the mounting plate (606) is close to the workpiece; then the double-shaft motor (6071) drives the double-shaft screw rod (6072) to rotate, the double-shaft screw rod (6072) drives the groove plates (6074) on the two groove blocks (6073) to be close to each other, so that the vertical plates (6076) are attached to the outer wall of a workpiece, the width of the workpiece is measured through the second sensing probes (6077) in the corresponding two vertical plates (6076), and as a plurality of the two sensing probes are arranged, the different positions of the workpiece are measured at the same time, and the distance between the two second sensing probes (6077) is the width of the workpiece;
s4, after the size of the workpiece in the required direction is measured, the rotating plate (4074) is driven to rotate by the rotating motor (4073), at the moment, the position of the workpiece is changed, the size of the workpiece can be measured again through the steps, and the required size of the workpiece can be obtained through cyclic action;
s5, when the moving wheel (703) is driven to move by the air cylinder (702) to enable the moving wheel (703) to move out of the bottom groove (701), and then the workbench (1) can be moved by the moving wheel (703).
