The non-contact type revolution surface profile measuring device for the large-scale revolution body part according to claim 8, wherein the sliding groove is in a rectangular groove shape, one end face of the sliding groove is open, the other end face of the sliding groove is closed, the length of the sliding groove is greater than the width of the measuring window, and two sliding grooves are provided; the two sliding grooves correspond to each other and are fixedly arranged on the lower side protection plates at two ends of the measuring window in parallel; the sealing door is in a rectangular plate shape, the size of the sealing door is not smaller than that of the measuring window, and two ends of the sealing door are respectively embedded in the two sliding grooves; the two extension springs are arranged on the two ends of the sealing door one by one correspondingly; the free ends of the two extension springs are correspondingly arranged on the other end face of the sliding chute one by one; the extension spring can pull the sealing door to move along the sliding groove; the magnetic coil is arranged on the lower side protection plate, the magnetic line of force is sleeved on the metal pull rod, and meanwhile the magnetic coil is electrically connected with the main controller and the battery respectively.
10. The non-contact type revolution surface profile measuring device for the large-scale revolution body part as claimed in claim 5, wherein the upper computer sends a measuring instruction to the non-contact type revolution surface profile measuring device for the large-scale revolution body part through a wireless transmission device, and the non-contact type revolution surface profile measuring device for the large-scale revolution body part starts to operate and measure after receiving the measuring instruction, and the measuring process is as follows:
1) the main controller simultaneously sends scanning motion instructions to the driver and the distance sensor, the driver rotates the starting motor after receiving the motion instructions, the motor drives the ball screw to rotate along the circumferential direction, and the ball screw drives the distance sensor to move downwards through the nut and the sliding block; when the distance sensor moves downwards, the grating ruler records the moving distance of the distance sensor in real time and transmits monitoring displacement data to the main controller in time; after receiving the scanning instruction, the distance sensor starts to scan the workpiece to be detected and transmits scanning data to the main controller;
2) the main controller timely records the displacement data and the scanning data in an internal memory after receiving the displacement data and the scanning data until the distance sensor displaces to a set distance;
3) and the main controller transmits all the measurement data to the upper computer through the wireless transmission module, and the measurement process is finished.
