Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber processing, in particular to a lifting mechanism for drilling carbon fiber pipes. Background Art

[0002] Carbon fiber tubes have the advantages of high temperature resistance, corrosion resistance, wear resistance, high strength, long life, corrosion resistance, light weight and low density. They are widely used in aviation model aircraft, lighting brackets, medical equipment, sports equipment and other mechanical equipment.

[0003] During the application process, the carbon fiber tube will be punched according to the use requirements. Usually, the tube is fixed on the workbench before drilling. In most cases, multiple holes need to be drilled at different angles of the tube. At this time, the tube needs to be manually rotated to adjust the drilling angle. When the tube is rotated, the tube contacts the table surface of the workbench, which can easily scratch the surface of the tube, causing damage to the surface of the carbon fiber tube and affecting the appearance. In severe cases, the tube needs to be repaired, which is not conducive to the work. Utility Model Content

[0021] Specifically, a through hole 13 is formed on the vertical plate 3 , and the turntable of the rotary cylinder 4 passes through the through hole 13 .

[0022] In this embodiment, the through hole 13 is used as a avoidance design to facilitate the connection between the rotary cylinder 4 and the internal expansion clamp 5. The internal expansion clamp 5 is a clamping device, mainly composed of three parts: a clamp body, a tightening screw and a center shaft. When in use, the clamp body is inserted into the clamped workpiece, and the outer surface of the workpiece is clamped by rotating the tightening screw to generate resistance, thereby achieving the effect of fixing and clamping.

One end of the pipe is placed on the core shaft of the internal expansion clamp 5 for expansion, and the other end is placed on the arc clamp block 10 for clamping.

[0029] When in use, one end of the pipe is put on the core shaft of the internal expansion clamp 5 for expansion and tightening, and the other end is placed on the arc clamping block 10 for clamping. The pipe is lifted by the jacking cylinder 2 to achieve the separation of the pipe from the workbench, and the pipe is continued to be lifted upward to the rotating drill bit to perform the drilling operation.

The tube is lifted by the lifting cylinder 2 to achieve the separation of the tube from the workbench, and the tube is continued to be lifted upward to the rotating drill bit for drilling operation. The rotary cylinder 4 can drive the tube to rotate axially to a certain angle, which is convenient for drilling holes at different angles in the tube. The structure of the mechanism is simple and is conducive to the development of work.
