Automatic pipe centering clamping and rotating device for laser cutting

Abstract

The invention relates to an automatic pipe centering clamping and rotating device for laser cutting. The automatic pipe centering clamping and rotating device comprises a base body, the base body is provided with a main shaft connecting bearing, the base body is connected with a main shaft body sleeving an outer ring of the main shaft connecting bearing in a sleeved mode through the main shaft connecting bearing, the base body is provided with a rotating mechanism for driving the outer ring of the main shaft connecting bearing to rotate, the main shaft body is rotationally connected with a synchronous movement mechanism, the main shaft body is connected with a guide rail base, the guide rail base is provided with an air cylinder driving assembly for driving the synchronous movement mechanism to operate, and the synchronous movement mechanism is connected with a plurality of clamping units used for clamping pipes. According to the automatic pipe centering clamping and rotating device for laser cutting, the pipes of different specifications and sizes can be automatically clamped at a time in a full stroke, the pipes can also be driven to synchronously rotate, so that the pipe circumferential cutting advantage is realized, moreover, the synchronous movement of the clamping units is ensured by arranging the synchronous movement mechanism, so that the centers of the pipes are concentric with the rotating center of the main shaft of the automatic pipe centering clamping and rotating device, clamping and positioning are reliable, so that the precision of cutting is guaranteed.

Description

technical field [0001] The invention relates to the technical field of clamping equipment for laser tube fittings, in particular to an automatic centering clamping and rotating device for tubes used for laser cutting. Background technique [0002] As a fast and efficient processing method, laser cutting is widely used in many industrial fields. In the application of pipe cutting, a device is needed that can hold the pipe well and drive it to rotate. At present, the manual clamping devices on the market require manual operation for clamping, which is slow in speed, small in clamping force, low in precision, and only realizes the clamping function, so the work efficiency is low. Although the conventional automatic clamping device can realize the clamping and rotating functions of the pipe, there are problems such as low clamping accuracy, poor coaxial accuracy, small size range of the clamping tube, large rotational inertia, and abnormal noise when the rotation speed is change...
