Single-row and double-row side peripheral clamp switching device

The utility model discloses a single-row and double-row side peripheral clamp switching device comprising an air cylinder or a hydraulic cylinder arranged on a single-row and double-row side peripheral clamp substrate; the end part of a piston rod of the air cylinder or the hydraulic cylinder is hinged with a sliding plate, a sliding seat is fixed on the upper surface of the sliding plate, and provided with a linear guide rail in a sliding manner, and one end part of the linear guide rail is connected with the single-row and double-row side peripheral clamp substrate. The single-row and double-row side peripheral clamp switching device has the advantages that the sliding plate is arranged on the single-row and double-row side peripheral clamp substrate and is driven by the air cylinder to move linearly; therefore, when the side periphery of an automobile is processed and manufactured, a positioning-supporting assembly can be installed on the sliding plate according to the designed single-row and double-row si
