A Universal Fixture for Rotary Table Chuck with Laser Precise Positioning

Abstract

The invention provides a rotary table chuck universal fixture for laser precise positioning. The fixture comprises a rotary hollow shaft, a main support, two outer side adjusting mechanisms and four inner side adjusting mechanisms. The rotary hollow shaft is in a hollow cylinder shape of a two-layer lantern ring structure. The rotary hollow shaft comprises an inner ring and an outer ring which are connected through a bearing. The center axis of the inner ring coincides with that of the outer ring. A locking pin structure is arranged between the inner ring and the outer ring. The outer ring of the rotary hollow shaft is fixedly connected with the main support through a flange along the axial end, and the outer radial rotary face at the other end is used for being clamped to a three-jaw or multi-jaw chuck of a rotary table. The inner ring of the rotary hollow shaft is internally provided with a two-way emitting laser indicator and a laser distance measuring device. The eccentric distance between the measuring position of the laser distance measuring device on a butterfly plate and the rotary center point of the butterfly plate is larger than 1 mm. The rotary table chuck universal fixture for laser precise positioning is precise in positioning, reliable in clamping, convenient to adjust, good in adaptability, flexible to disassemble and assemble, easy to manufacture and low in cost.

Description

technical field [0001] The invention belongs to the technical field of laser application, and in particular relates to a universal fixture for a rotary table chuck with precise laser positioning. Background technique [0002] The laser cladding process has the advantages of high energy density, small deformation, narrow heat-affected zone, high cladding speed, easy automatic control, and no subsequent processing. In recent years, it is becoming an important means of metal material processing and manufacturing, and it is becoming more and more widely used It is widely used in automotive, aerospace, defense industry, shipbuilding, ocean engineering, nuclear power equipment and other fields, and the materials involved cover almost all metal materials. [0003] During the laser cladding process, the workpiece needs to be clamped and fixed by special fixtures. For workpieces with irregular shapes or eccentric structures, clamping and fixing has always been a problem. For example...

Problems solved by technology

For example, the traditional three-eccentric butterfly valve butterfly plate processing fixture generally adopts a special oblique die for inclined cone surface processing that makes the centerline of the cone coincide with the turning centerline of the lathe, but the manufacturing accuracy of this kind of fixture is very difficult to guarantee, and the cost is high.
