Abstract

The invention provides a dynamic tool tip position calibration method and system based on an optical locator, a medium and equipment. The method comprises the steps of constructing a structure; mounting an optical positioning device by forming a conical groove in a specific surface position of a reference block, and mounting the optical locater in a specific position; preparing for data collectionby tightly jacking the tool tip against the groove of the reference positioning block, and preparing to acquire data; acquiring attitude information by rotating a tool around the tool tip , and acquiring the attitude information of the tool and the attitude information of the reference positioning block through the optical locator; and acquiring relative attitude information by transmitting the acquired information to a conversion algorithm, transmitting the attitude information of the tool relative to the reference positioning block into a spherical fitting algorithm, and obtaining the offset coordinates of the tool tip phase under a tool coordinate system. According to the invention, the purpose of obtaining accurate tool tip offset data can be achieved, and meanwhile calibration operation becomes more convenient.

Description

technical field

[0001] The present invention relates to the field of optical locators, in particular to a dynamic calibration method, system, medium and equipment based on the position of the tip of a tool based on the optical locator. Background technique

[0002] The offset data of the tool tip is an important data commonly used in engineering calculations. The accuracy of the offset data of the tool tip will directly determine the accuracy of the engineering calculation. Typically, the source of the offset for the tip position is the engineering drawing, but the actual offset depends on machining accuracy. However, machining accuracy is sometimes difficult to guarantee. At this time, the actual offset of the tip cannot be guaranteed, which affects the accuracy of engineering calculations.

[0003] Patent document CN205215354U discloses a tip calibration method, the calibration device of this method is very complicated, the machining accuracy is difficult to guarantee, a...
