[0034] A display screen 13 is installed on one side of the laser rangefinder 12;

[0035] It should be noted that when the gear shaping machine with adjustable tool position is in use, the servo motor 7 is first connected to the control system of the gear shaping machine body 1, and the control system is used to set the forward and reverse programs for the servo motor 7. After the workpiece is clamped and fixed by the fixture, the laser rangefinder 12 is turned on, and the lead screw 5 is driven to rotate by the servo motor 7, so that the ball 9 rolls on the inner side of the guide groove 6, and then the movable seat 8 drives the gear shaping cutter 3 to approach the workpiece. The laser rangefinder 12 and the reflector 11 can accurately measure the moving distance of the gear shaping cutter 3, and the data is displayed on the display screen 13 for the convenience of the staff to watch, so that the gap between the gear shaping cutter 3 and the workpiece can be accurately controlled to ensure the processing accuracy of the workpiece, and then the gear shaping cutter 3 is driven up and down by the telescopic spindle 2 to process the workpiece.
