Centering and jacking device for short-stroke pipe

Abstract

The invention designs a centering and jacking device for a short-stroke pipe. According to the technical scheme, the centering and jacking device comprises a base, wherein the base is connected with a centering and jacking assembly through a lifting driving assembly, the lifting driving assembly can drive the centering and jacking assembly to do lifting motion on the base, a rotary driving assembly is arranged on the centering and jacking assembly, and the centering and jacking assembly is connected with a centering rod folding assembly; and the rotary driving assembly can drive the centering rod folding assembly to rotate in the horizontal direction, and a folding driving assembly is arranged on the centering rod folding assembly and can drive the centering rod folding assembly to move from the horizontal folding state to the vertical working state. The jacking function is achieved through driving of the lifting driving assembly; the centering and jacking assembly is matched with the centering rod folding assembly to center and clamp the to-be-machined pipe; and the centering rod folding assembly can be folded to be parallel to the horizontal plane when not working, the height of the whole device is greatly reduced, the height of a lathe bed of a pipe cutting machine is reduced, the structural compactness is improved, and space is saved.

Description

technical field [0001] The invention relates to the technical field of laser cutting, in particular to a pipe centering and jacking device. Background technique [0002] Nowadays, the metal processing industry pays more and more attention to the use of laser cutting. Laser cutting has the advantages of high speed, high efficiency and high precision. It is especially important for the cutting efficiency of professional laser pipe cutting machines. It is inevitable that there will be more or less deviations in the same position. Among them, there is a certain inclination for the pipe cutting machine body, which is the most fatal shortcoming. At this time, it is necessary to equip the laser pipe cutting machine with a certain deviation correcting jacking device, that is, a centering jacking device. For slender pipe processing, if only two three-jaw chucks are used for clamping, because the pipe is thin, there will be a collapse in the middle, and the situation will be more ser...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a short-stroke pipe centering jacking device. The technical problem it can solve is that the jacking distance of the jacking device is relatively high, which makes the overall length of the jacking cylinder longer, resulting in cutting The bed structure of the tube machine is large in height, and the structure is not compact enough, which takes up a lot of unnecessary space
