Description

Technical Field

[0001] The utility model relates to the technical field of welded pipe fixing, in particular to an inner and outer locking type locomotive welded pipe fixing device. Background Art

[0002] Each component of a motorcycle frame is made through machining and then assembled into a bicycle frame. Machining refers to the process of changing the size or performance of a workpiece through a mechanical device. Turning, milling, planing, grinding, cutting, welding, etc. all belong to machining, among which welding is a common method of workpiece processing. Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Frame welded pipes are a common part of mechanical equipment. Traditional locomotive welded pipes are mostly welded and fixed by two welded pipes, while inner and outer locking locomotive welded pipes are fixed by two welded pipes through a connecting sleeve.

[0003] However, when some internal and external locking locomotive welded pipes are butt-jointed, two welded pipes are usually held manually and then butt-jointed, which results in poor butt-jointing effect and affects subsequent fixing work. In addition, the manual holding and lifting workload is large, time-consuming and labor-intensive. Therefore, we propose an internal and external locking locomotive welded pipe fixing device to solve the above problems. Utility Model Content
