Problems solved by technology

In a conventional jet processing machine tool, it is necessary to be equipped with at least two rotating axes to realize two free angle adjustments of the nozzle, so the volume and range of motion of the machine tool's kinematic mechanism are large, and the development cost of the machine tool is very high. At the same time, the movement of each axis The control algorithm becomes extremely complex

Abstract

The invention provides a jet polishing compound machine tool. The compound machine tool adjusts an injecting angle of a rotating nozzle through a parallel mechanism, so that the axis of a main shaft is consistent with the normal vector direction in a workpiece surface machining point, and the precise positioning of the normal direction of a free curved surface of a workpiece along with machining functions and any angles can be realized. An X-axle slide block is provided with a working mode switching joint for replacing two vector nozzles for the parallel mechanism; one is a two-dimensional superposition vector nozzle structure scheme; and the other one is a spherical hinge vector nozzle structure scheme. The jet polishing compound machine tool has the advantages of small and compact structure and relatively simple motion shaft control algorithm, and can replace a conventional multi-shaft machine tool for jet polishing curved surface machining.

Description

Technical field [0001] The invention belongs to the field of mechanical processing devices, and specifically relates to a jet polishing composite machine tool. Background technique [0002] In the process of jet polishing machining of curved workpieces, the forming spot polishing technology requires that the jet direction of the nozzle should always be maintained at a certain angle with the normal vector direction of the workpiece surface. At the same time, the nozzle rotates around the spindle axis and forms a Gaussian spot after one revolution. . The axis of the spindle must be consistent with the direction of the normal vector at the processing point on the surface of the workpiece, and the Gaussian spot is moved through the feed to perform polishing processing in the surface normal following mode. In conventional jet processing machine tools, at least two rotating shafts are required to realize the two free angle adjustments of the nozzle. Therefore, the volume and range of ...
