Parameter verification device, system and method for special-shaped machined part

Abstract

The invention discloses a parameter verification device, system and method for a special-shaped machined part. The device comprises a positioning part which is provided with a bearing body which is arranged in an inclined manner, wherein the bearing body bears a first tracer; and a verification part which is arranged on the bearing body. According to the invention, the parameter verification device is installed on an inclined plane instead of being installed on a vertical plane in the prior art, and the inclined plane of the parameter verification device provided by the invention can be parallel to an optical tracker, so that the optical tracker can be aligned at the tracer on the optical tracker. According to the parameter verification method for the special-shaped machined part, the accuracy problem of the measurement precision after an operating device is installed at the tail end of a mechanical arm is solved, and the stability and reliability of the system precision are guaranteed.

Description

technical field [0001] The invention relates to the field of precision verification of processed parts, in particular to a parameter verification system and method for special-shaped processed parts. Background technique [0002] Robotic surgery system is a complex integrating multiple modern high-tech means, which has a wide range of uses and has a large number of clinical applications in surgery. Surgeons can operate the machine away from the operating table, which is completely different from the traditional concept of surgery, and it is a well-deserved revolutionary surgical tool. During surgery, it is usually necessary to install an operating device at the end of the robotic arm to directly manipulate the surgical operation. Considering the safety of surgical operations, accuracy is one of the important parameters that determine whether a robot can be used in surgery, and the difference in the design and processing accuracy of the end-of-manipulator device will directl...

[0003] However, due to the different types of operations, the end-effectors also have different shapes and functions, so they cannot be directly measured. Only indirect methods can be used to measure the positional relationship of some key points, and how to determine the positional relationship of these measurement points It is very difficult to evaluate the accuracy of

[0004] In addition, the tracer of the existing parameter verification device is installed on a vertical surface, and there is always a certain angle between the optical tracker and the tracer on the parameter verification device and the mechanical arm.
