Technical Field
[0001] The utility model relates to the technical field of steering systems, in particular to a device for quickly calibrating and positioning the mechanical zero point position of a rotating spindle. Background Art
[0002] The precision tool changing turret is an important part of automated machining equipment. In daily turret maintenance and repair work, the turret spindle must re-calibrate the mechanical position of the spindle rotation into position sensing groove after replacing the bearing. The sensing groove is processed on a round nut and installed and fixed to the upper end of the spindle. The position of the sensing groove must be distributed vertically at 90° with the flat key on the lower end face of the spindle. The sensing position of the spindle rotation into position sensor is called the spindle mechanical 0 point. If the calibration and positioning of the spindle mechanical 0 point sensing position is inaccurate, it will directly affect the accuracy of the turret 0 point calibration. The spindle mechanical 0 point sensing groove is on the nut at the upper end of the spindle, and the calibration reference point flat key is on the lower end face of the spindle. Due to the structural distribution, the spindle mechanical 0 point calibration and positioning operation is difficult. Previously, the measurement method of guiding the extension of the reference point was used for measurement, calibration and positioning, which resulted in large errors and seriously affected the accuracy of the spindle 0 point calibration.
[0003] The 0-point calibration and working principle of the turret: The turret is driven by a servo motor to rotate the turret spindle. After the spindle rotates to the tool change angle with the servo motor, the spindle mechanical 0 point must rotate to the precise position where it meshes with the tool spindle in the turret. The 0-point calibration of the turret means that the motor 0 point must correspond to the spindle's own mechanical 0 point. During the tool change cycle of the turret with the 0-point calibration, the gear meshing must be smooth, and no jamming, interference or collision is allowed. This requires that the position setting of the spindle mechanical 0 point must be accurate. If the spindle itself If the mechanical 0-point sensing position calibration is not accurate, it will directly affect the accuracy of the turret 0-point calibration, causing poor meshing between the rotating toothed disc on the turret body and the loose teeth of the spindle during the tool change cycle, resulting in collision or biting; it will cause the meshing interference between the spindle flat key and the tool shaft slot, causing abnormal rotation of the turret spindle, and the turret retraction lock will be misaligned, causing the turret spindle loose teeth and the gear wear and damage of the turret body toothed disc, resulting in inconsistent gear clearance size, and causing serious faults such as reduced turret precision and life. Therefore, how to ensure the accuracy of the turret spindle mechanical 0-point sensing position calibration is an urgent problem that our machine repair department needs to solve.
