AI Technical Summary

Technical Problem

The prior art is difficult to perform high-precision positioning and processing of large-sized slewing parts in the field of wind power. Traditional pneumatic chucks have excellent effects in clamping small parts but are not suitable for large-sized parts. Multi-point clamping tools have insufficient accuracy.

Method used

A clamp including a load table, a limiting assembly and a downward pressure assembly is designed. Through the cooperation of the load table and the downward pressure assembly, the vertical and horizontal positioning of the workpiece is achieved by using the static friction force of the limiting assembly and the downward pressure assembly.

Benefits of technology

It realizes rapid positioning of workpieces with larger sizes and high positioning accuracy, which can meet the high-precision processing needs of key components of wind power.

Abstract

The utility model discloses a clamp for precisely machining key wind power parts, and belongs to the technical field of clamps. The clamp comprises a bearing table, a limiting assembly and a downward pressing assembly, the limiting assembly and the downward pressing assembly are both installed on the bearing table, a workpiece to be machined is arranged on the bearing table, a clamping space is formed in the inner side of the limiting assembly and used for limiting the workpiece in the horizontal direction, and the bearing table is matched with the downward pressing assembly. The positioning device is used for positioning the workpiece in the clamping space. The bearing table is matched with the downward pressing assembly to limit the vertical position of the workpiece, the limiting assembly can rapidly limit the horizontal position of the workpiece, rotation of the workpiece is limited by static friction force borne by the workpiece under the pressure action of the downward pressing assembly, and the clamp can rapidly position the workpiece large in size and is high in positioning precision.
