Description

Technical Field

[0001] The utility model relates to the technical fields of industrial robots and composite machining equipment manufacturing, and particularly relates to a positioning auxiliary device. Background Technique

[0002] Industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices widely used in the industrial field. They have a certain degree of automation and can rely on their own power sources and control capabilities to achieve various industrial processing and manufacturing functions. During the manufacturing process, composite machining equipment is also required. Composite machining equipment is an advanced manufacturing equipment that integrates multiple processing technologies and functions.

[0003] The manufacturing of industrial robots and composite machining equipment has extremely high precision requirements. Therefore, in order to more accurately measure, calibrate, and adjust the positions, angles, and motion trajectories of each component, and ensure that the final product meets the high-precision standards required by the design, a positioning auxiliary device is needed.

[0004] When the existing positioning auxiliary device positions a workpiece, in order to ensure the stability of the workpiece, a fixture is usually used to position the workpiece. However, when the existing fixture positions the workpiece, it usually judges whether the workpiece is fixed tightly by manual judgment or pulling the workpiece. Therefore, during the auxiliary positioning process of the workpiece, it is extremely easy to occur that the workpiece is not fixed tightly or fixed too tightly, resulting in deformation and damage of the workpiece. At the same time, a large amount of waste chips and impurities are generated during the manufacturing of the workpiece. The waste chips and impurities adhere to the workpiece, which will cause the fixture to be unstable when fixing the workpiece and scratch the workpiece. To solve this problem, we propose a positioning auxiliary device. Content of the Utility Model
