Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] The welding frock structure of the front triangle of a titanium alloy bicycle provided by the invention is as follows: figure 1 As shown, it includes a bottom plate 17, a fixed plate 1, a support plate 10 and a positioning device, wherein the fixed plate 1 is fixed on the bottom plate 17 with bolts. Two support plates 10 are arranged parallel to the direction perpendicular to the fixing plate 1, and are used to support the titanium alloy tube 5 of the bicycle front tripod. Each titanium alloy tube 5 and the support plate 10 are provided with a tube spacer 4 at the junction of each titanium alloy tube 5, which is used to support and fix the The titanium alloy pipe 5 and the pipe spacer 4 are composed of a spacer a11 and a connecting block 12. The spacer b11 is provided with a groove 13 which is consistent with the diameter of the titani...

Abstract

The invention discloses a front triangular welding fixture of a titanium alloy bicycle, which comprises fixing plates fixed on a bottom plate and two supporting plates; the middle part of the fixing plates is provided with a slide rail; two supporting plates are in parallel to the fixing plates and located at the same side of the fixing plates; a titanium alloy pipe is used for supporting and fixing the front triangular frame of a bicycle. The front triangular welding fixture of the titanium alloy bicycle has the advantages of being simple in structure, convenient to operate; through a circular water cold device, the rapid cooling of the welding part is realized, the influence of a hot influence wide zone and welding deformation is reduced; the welding seam quality is improved; besides, the practicability is strong, and the assembly degree of freedom is big; the front triangular welding fixture can be applied to weld and repair various types of bicycle frames.

Description

technical field [0001] The invention belongs to the technical field of nonferrous metal processing, and relates to a titanium alloy bicycle front triangle welding tool. Background technique [0002] The fast-paced development of modern urban life has made people have higher and higher requirements for travel vehicles. Traditional bicycle frames are made of stainless steel and other alloy materials, which are heavy and not convenient to use. Titanium and titanium alloy pipes have high strength. , good corrosion resistance, high and low temperature resistance and other advantages have been widely used in various bicycle frames at home and abroad. As a highly active metal, titanium is easy to react with elements such as hydrogen and nitrogen during welding in air to cause weld embrittlement, and titanium has low thermal conductivity and wide welding heat-affected zone. Thin-walled titanium and titanium alloys that require high dimensional accuracy The welding of curved surface...
