Cut-off device for fusion welding of automobile parts

Abstract

The invention discloses a cut-off device for fusion welding of automobile parts. The cut-off device comprises a workbench, a mechanical arm mechanism and a cut-off mechanism; a controller is mounted on the front surface of the workbench; the mechanical arm mechanism comprises two support frames, a first hinge arm, a second hinge arm and a third synchronous motor; a first synchronous motor is mounted on the inner side wall of each support frame; the inner side wall of the first hinge arm is welded to an output shaft of the first synchronous motor; and a second synchronous motor is installed on the front surface of the first hinge arm. The cut-off mechanism is matched with the mechanical arm mechanism, a laser range finder is used as a measurement basis, and feeding adjustment of a ball screw and driving between a rack and two sets of rockers are matched, so that parameterization adjustment is conducted on straight seam pipes with different cut-off length requirements, the cut-off requirement under the actual condition is met, and overload protection can be carried out on a saw blade according to different deflection resonance phenomena caused by the straight seam pipes made of different materials by means of a torsion limiter.

Description

technical field [0001] The invention relates to the technical field of auxiliary devices for fusion welding of automobile parts, in particular to a cutting device for fusion welding of automobile parts. Background technique [0002] In the structural parts of automobiles, straight seam high-frequency welded steel (aluminum) pipes are essential metal parts. Straight seam high-frequency welded steel pipes are rolled steel strips of a certain size into a round tube, and then The steel pipe made by high-frequency welding technology is characterized by high production speed and continuous feeding and discharging. After welding, the continuous steel pipe is cut into a certain length of steel pipe by a cutting machine. ; [0003] It is also because of the production characteristics of this kind of steel pipe. In the prior art, due to processing errors or more than welding, there will be some materials that do not meet the product requirements, and this material will become waste, ...

AI Technical Summary

Problems solved by technology

[0003] Also because of the production characteristics of this steel pipe, in the prior art, due to processing errors or excessive welding, some materials that do not meet the product requirements will appear, and this section of material will become waste, which needs to be cut off by the staff; the traditional The truncation process requires staff to manually truncate with a chainsaw or an angle grinder. This convenience consumes a lot of manpower and material resources, time-consuming and labor-intensive, and the truncation opening cannot be guaranteed to be smooth, and it will be even larger when encountering inclined and bent special-shaped pipes. Increased the operational difficulty of the staff, and could not adapt to the high efficiency and high quality process requirements of the enterprise;
