Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The balance arm welding positioning device shown in fig. 1 to 4 comprises a platform 1, a bracket 2 and a positioning mechanism 3.

The two opposite ends of the platform 1 are provided with brackets 2, the opposite surfaces of the two brackets 2 are provided with three pairs of ear seats 4, and the three pairs of ear seats 4 are sequentially arranged on the brackets 2 from top to bottom; the length of the ear seat in the middle is less than that of the ear seats on the two sides, so that the balancing arms with different lengths can be assembled. It should be noted that one of the two brackets is fixedly connected to the platform, and the other bracket is movably connected to the platform, for example, a roller (not shown in the figure) is provided on the bracket, the roller can slide on the platform to adjust the distance between the two brackets, so as to assemble the balance arms with different lengths, and the bracket and the platform can be fixed by bolts, so as to be fixed at different positions on the platform, so as to facilitate the welding of the balance arms.
