Automatic positioning and tensioning universal device for rocker arms

Abstract

A universal automatic positioning and tensioning device for rocker arms is mainly used for automatic positioning and clamping during rocker arm machining. It consists of a tensioning component, a positioning component, a limiting component, and a driving component. The inner cavity of the tensioning block at the upper end of the tensioning mandrel of the tensioning component is adapted to the upper end of the hexagonal bevel screw. The positioning block of the positioning component is fixed to the fixture base plate. The limiting block of the limiting component is fixed to the fixture base plate, with its inner surface facing the upper plane of the threaded hole of the rocker arm. The cylinder end of the block-shaped hydraulic cylinder of the driving component is fixed to the fixture base plate by a hexagonal bevel screw, and the piston rod end of the block-shaped hydraulic cylinder is connected and fixed to the lower end of the hexagonal bevel screw. The cylinder end of the single-acting cylinder is fixed to the inner surface of the side clamping support block, with its piston rod end facing the lower plane of the threaded hole of the rocker arm. This invention has strong versatility, high positioning accuracy, and simple operation. It can adapt to the machining needs of parts of different shapes and sizes, eliminates the need for frequent fixture changes, reduces production costs, and improves production efficiency.
