Description
技术领域 technical field
本发明涉及摩托车车架焊接工装夹具，具体指一种摩托车车架后体总成焊接夹具，属于工装夹具技术领域。 The invention relates to a welding jig for a motorcycle frame, in particular to a welding jig for a rear body assembly of a motorcycle frame, and belongs to the technical field of jigs.
背景技术 Background technique
摩托车车架是摩托车的核心部件之一，支撑着车身、骑乘者和所有载货的重量，承担着重要的安全职能。摩托车车架结构十分复杂，由许多金属管焊接而成一个空间立体结构，并根据实际安装需要，焊接有许多功能支耳和金属板。摩托车车架几乎都是通过焊接形成，因此为了焊接所需，设计有许多焊接夹具，焊接夹具主体为将焊接部件定位的定位机构和将焊接部件压紧以防止松动的快速压夹机构。焊接时，先将需要焊接的部件放置在夹具中并通过快速压夹压紧，然后开始焊接；焊接完毕，再打开快速压夹机构，即可将焊接在一起的产品从定位机构中取出。由于摩托车车架的组成部件非常多，且零散，因此目前通常先将摩托车车架分解为几大部分分别焊接成型，再将这焊接成型的几大部分组合焊接在一起形成总成，由于操作者专门焊接某固定位置，这样可以提高生产效率和质量。 The motorcycle frame is one of the core components of the motorcycle, supporting the weight of the body, rider and all cargo, and undertaking an important safety function. The structure of the motorcycle frame is very complicated. It is welded by many metal pipes to form a three-dimensional structure. According to the actual installation needs, many functional lugs and metal plates are welded. Motorcycle frames are almost all formed by welding, so many welding fixtures are designed for welding. The main body of the welding fixture is a positioning mechanism for positioning the welding parts and a quick clamping mechanism for pressing the welding parts to prevent loosening. When welding, first place the parts to be welded in the fixture and press them through the quick clamp, and then start welding; after welding, open the quick clamp mechanism, and the welded products can be taken out from the positioning mechanism. Because the components of the motorcycle frame are very many and scattered, at present, the motorcycle frame is usually decomposed into several parts and welded separately, and then the welded parts are combined and welded together to form an assembly. Operators specialize in welding certain fixed positions, which can improve production efficiency and quality.
比如，现有技术中有一款摩托车车架，其车架后体总成由右半体组合、左半体组合、用于油箱安装的油箱后安装支架组件、用于连接左右半体组合的左右连接板和用于座垫锁安装的座垫锁安装支架组件构成，其中右半体组合和左半体组合对称布置且分别由主管、支撑管和车架后加强板三部分焊接构成，支撑管斜向下方，油箱后安装支架组件、左右连接板和座垫锁安装支架组件位于车架后体总成前部、中部和尾部，油箱后安装支架组件、左右连接板和座垫锁安装支架组件左右两侧分别设有弧型卡槽，以卡在左右半体组合上的左右主管对应位置上。作为车架总成，在车架后体总成前端还需要焊接前主管和立管等构件，前主管位于左右半体组合的左右主管前端之间并焊接在一起。虽然车架后体总成由上述五部分构成，但在实际焊接时，由于其为立体异形构造，所以其焊接前各部分的夹持定位非常麻烦，不光定位效率低，而且定位精度不高，影响最终成型质量。 For example, there is a motorcycle frame in the prior art. The rear body assembly of the frame is composed of a right half body combination, a left half body combination, a fuel tank rear mounting bracket assembly for fuel tank installation, and a rear mounting bracket assembly for connecting the left and right half bodies. The left and right connecting plates are composed of the seat lock installation bracket assembly used for the installation of the seat cushion lock. The right half body combination and the left half body combination are arranged symmetrically and are composed of three parts welded by the main pipe, the support pipe and the rear reinforcement plate of the frame respectively. The pipe is inclined downward, the fuel tank rear mounting bracket assembly, the left and right connecting plates and the seat cushion lock mounting bracket assembly are located at the front, middle and rear of the frame rear body assembly, the fuel tank rear mounting bracket assembly, the left and right connecting plates and the seat cushion lock mounting bracket The left and right sides of the component are respectively provided with arc-shaped card slots to be locked in the corresponding positions of the left and right main pipes on the combination of the left and right halves. As a vehicle frame assembly, components such as the front main pipe and the standpipe need to be welded at the front end of the rear body assembly of the vehicle frame. Although the frame rear body assembly is composed of the above five parts, in actual welding, due to its three-dimensional special-shaped structure, the clamping and positioning of each part before welding is very troublesome, not only the positioning efficiency is low, but also the positioning accuracy is not high. Affect the final molding quality.
