The invention discloses an automobile instrument desk tubular beam tooling support, which comprises a first frame, a second frame and a third frame. The second frame is installed at one end of the topof the first frame, and the third frame is installed on the top of the second frame; the middle end of the top of the first frame and the bottom of one end of the third frame are correspondingly andhorizontally provided with mounting plates, the end, away from the second frame, of the top of the first frame is connected with a mounting frame, the opposite sides of the mounting frame and the second frame are correspondingly provided with connecting plates, and two groups of first oil cylinders are installed between the end part of the third frame and the mounting plates and between the end part of the second frame and the connecting plates. According to the automobile instrument desk tube beam tooling support, contraction of second oil cylinders at both ends drives a stressed plate to move towards the inner part of a tubular beam continuously, the stressed plate can not only straighten the tubular beam, but also expand the tubular beam in the process of straightening, so that the tubular beam can be processed to be various forms simultaneously, and processing efficiency is high.
