The invention relates to a shell part high-precision interchange device which solves the problems that time and energy are wasted, cost is high and production efficiency is low, wherein the problems exist in interchange processes of existing shell part tools. The shell part high-precision interchange device comprises a right-angle-shaped base, a plurality of pre-positioning rods are evenly arranged on the inner end surface of a vertical plate of the base by using the center of the inner end face as the centre of a circle, annular interchange bases are arranged in the pre-positioning rods, the interchange bases are fixed with the base through self-raising pins, positioning pins penetrate through the interchange bases and the base, workpiece positioning pins and supporting blocks are arranged on the interchange bases, lever cylinders which are located around the interchange bases are fixed on the base, pressing plates are arranged on the lever cylinders, an energy accumulator and a connecting valve are arranged on the upper end surface of a horizontal plate of the base, hoisting rings and an oil pressure gauge are arranged on the upper end surface of the vertical plate of the base, and tool setting holes are arranged in the center position of the side surfaces of the vertical plate of the base. According to the shell part high-precision interchange device, structural design is reasonable and reliable, production efficiency is greatly improved, positioning precision of the interchange device is improved, and cost of tool manufacturing is reduced.
Description
technical field [0001] The invention relates to an exchange fixture for mechanical processing, in particular to a high-precision exchange device for shell parts. Background technique [0002] With the increasingly fierce market competition, the "multi-variety, medium and large batch, low-cost" production method has become the leading production method in the machining industry. Machining centers have become the main processing equipment for shell parts, and the tooling used in them is often bulky and heavy. In addition, different box parts often have relatively large differences in shape, volume, weight, etc., and the tooling is unique and not interchangeable, which does not meet the needs of the current production method. Contents of the invention [0003] In order to solve the problems of time-consuming, labor-intensive, high cost and low production efficiency in the exchanging process of existing shell parts tooling, the present invention provides a high-precision exch...
