Rotating device for laser carving

Abstract

The invention discloses a rotating device for laser carving, characterized in that the sub supporting mechanism (2) includes a first upper fulcrum bar (9), a second upper fulcrum bar (10), a first lower fulcrum bar (11), a second lower fulcrum bar (12), an elevating platform (3) and a screw (13), the first upper fulcrum bar and the first lower fulcrum bar, and the second upper fulcrum bar and thesecond lower fulcrum bar are hinged by a pin shaft (16) with screw, the elevating platform is mounted on the first upper fulcrum bar and the second upper fulcrum bar, a driven frictional wheel (4) ismounted on the elevating platform, the connecting end parts of the first upper fulcrum bar and the second upper fulcrum bar and the first lower fulcrum bar and the second lower fulcrum bar have toothparts (18, 19) and are engaged with each other, the screw matches to the pin shaft with screw. The invention uses this sub supporting mechanism to settle difficult problems of unsteady elevating of the processed goods in prior art, with simple structure and good stability to realize purpose of unexcentric elevating of the center.

Description

technical field [0001] The invention relates to a laser engraving device, in particular to a laser engraving machine for rotary engraving. Background technique [0002] At present, laser rotary engraving devices have various structures, among which there are many engraving devices with advanced structures, such as the "Coaxial Engraving Device" that Mr. Hu Wentang applied to the State Intellectual Property Office in 1995, and its patent number is: 95210245.5. But this coaxial engraving device is not suitable for processing objects that are cylindrical materials. Check the Chinese patent in addition, wherein the patent number is: 94192004.6, and the name is called in the international application of " roller supporting device and supporting method of engraving machine ", disclose following content: " a kind of engraving machine that is used for band headstock and tailstock a roll handling system, headstock and tailstock jointly rotatably supporting the roll at the engraving ...

AI Technical Summary

Problems solved by technology

As a result, there will be errors in the engraving position of the workpiece, and it will easily lead to an increase in the incidence of scrap

In addition, the engraved objects of this kind of engraving machine are generally cylindrical. When engraving, the cylindrical body is placed on the driving friction wheel and the driven friction wheel. When there is out-of-roundness, non-cylindricity or non-straightness, there will be insufficient friction, which often causes the cylindrical body to slide on the friction wheel, and the rotation accuracy cannot be controlled during rotation, which will also cause deviation of the laser engraving position
