Abstract

The invention relates to a locating device for machinin a butterfly spring. The locating device comprises a bottom plate, support columns, a locating plate, a fixing column, a fixing assembly, a discharging ring and a lifting mechanism; the top of the bottom plate is connected with the bottom of the locating plate through the four support columns, and the fixing column is movably arranged at the center of the locating plate in a penetrating mode; the discharging ring is detachably installed at the upper end of the fixing column through the fixing assembly, and the lower end of the fixing column is connected with the lifting mechanism. The locating device has the beneficial effects that, when the locating device for machining the butterfly spring is used, the discharging ring is detached from the fixing column, and a butterfly spring to be machined is installed on the fixing column through the fixing assembly; then, the fixing column is driven by the lifting mechanism to descend, and the discharging ring is driven by the fixing column to descend; and thus, the butterfly spring can be fixedly installed on the locating plate, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of disc spring processing, in particular to a positioning device for disc spring processing. Background technique [0002] The disc spring is a special spring that is conical in the axial direction and bears the load. After being deformed under the load, it stores a certain amount of potential energy. When the bolts are loose, the disc spring releases part of the potential energy to maintain the pressure between the flange connections. Sealing requirements. The stress distribution of the disc spring decreases evenly from the inside to the outside, which can achieve the effect of low stroke and high compensation force. The existing disc spring is inconvenient to locate the disc spring during processing, so a convenient disc spring positioning is needed. The positioning device to solve this defect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide ...
