Fixing platform for bicycles

Abstract

The invention provides a fixing platform for bicycles. The fixing platform comprises an operation platform, wherein a bracket is fixedly arranged in the position, close to the edge part, of the upper end face of the operation platform; a mounting shaft is arranged on the bracket; a top plate is arranged on the mounting shaft in a sleeving manner; the top plate performs rotation motion, with the mounting shaft adopted as the center line; guide blocks are symmetrically arranged in the positions, on one side of the top plate, in the operation platform, with the geometric center line of the operation platform adopted as the symmetry axis; a base plate is arranged between the symmetrically distributed guide blocks; limiting rods are further arranged on the base plate parallel to the guide blocks; the limiting rods and the operation platform are connected in a sliding manner; and the limiting rods comprise locating blocks used for limiting positions of the limiting rods. The fixing platform has the beneficial effects that two to-be-welded bicycle steel pipes are successfully subjected to butt joint through the arranged guide blocks, the two to-be-welded bicycle steel pipes are reinforced through the arranged limiting rods, and the problem that a weld joint is increased due to shaking during the welding process is avoided; and in the design, through well limiting the steel pipes, the flat welding quality is greatly improved.

Description

technical field [0001] The invention relates to the technical field of bicycle processing equipment, in particular to a bicycle fixing platform. Background technique [0002] During the manufacturing process of bicycles, steel pipes need to be welded to meet the structural design requirements of bicycle frames. In the welding process, the most common is flat welding, that is, two steel pipes are fixedly connected as a whole by welding on the same central axis. This welding process seems simple. However, in the actual operation process, if the two steel pipes are not firmly fixed or misaligned, it will have a serious negative impact on the welding quality, and then the strength of the welded steel pipe will be greatly reduced. This welded steel pipe cannot be used in the production and processing of bicycles because it cannot meet the high-strength requirements of bicycle frames, and can only be used as waste materials. [0003] It can be seen that how to develop a bicycle ...

Problems solved by technology

This welding process seems simple. However, in the actual operation process, if the two steel pipes are not firmly fixed or misaligned, it will have a serious negative impact on the welding quality, and then the strength of the welded steel pipe will be greatly reduced.

Since this kind of welded steel pipe cannot meet the high strength requirements of the bicycle frame, it cannot be used in the production and processing of bicycles and can only be used as waste materials
