Abstract

The invention relates to the technical field of laser cutting machining, in particular to a rotary body clamping and positioning jig and a cutting machine. The rotary body clamping and positioning jigcomprises a supporting component, a clamping component and a driving device; the clamping component comprises a pulling-pressing part, a aligning device and a fixing disc; the pulling-pressing part is connected with the aligning device; a plurality of positioning parts are arranged on the fixing disc, and a rotary body workpiece is clamped between the aligning device and the fixing disc and is positioned in a limiting space enclosed by the plurality of positioning parts; and the output end of the driving device is arranged at the center of the fixing disc in a penetrating mode. According to the rotary body clamping and positioning jig, the output end of the driving device, the axis of the rotary body workpiece, the central axis of the aligning device and the pulling-pressing part are located on the same straight line, so that the distance between the machining surface of the rotary body workpiece and a laser lens is fixed; and the driving device is started, the output end of the driving device drives the rotary body workpiece to rotate, so that the surface of the rotary body workpiece can be uniformly cut.

Description

technical field

[0001] The present application relates to the technical field of laser cutting, in particular to a clamping and positioning jig for a revolving body and a cutting machine. Background technique

[0002] Laser cutting process is to use high-energy-density laser beam to act on the target, so that the target surface generates enough heat to melt the material, and the high-pressure gas coaxial with the beam directly removes the molten material, so as to achieve the purpose of cutting. The lens of the laser processing equipment must keep a certain distance from the workpiece, and the appearance characteristics of the rotary body cannot meet the requirements of laser processing, so it is difficult to perform laser cutting on the rotary body workpiece. Based on this objective requirement, a special fixture is needed to Keep a fixed distance between the surface processing area of ​​the rotating body and the laser lens. Contents of the invention
