The invention relates to an indexing device used for the processing of a hexagon bolt die, the structure of the invention comprising: a ring base seat (1) is slantways arranged, ring support seats (2) in which level steps are arranged and are fixed through screws to the upper surface of the steps; also includes: an indexing device (10), consists of indexing discs (101) which are integrated and arranged in level and vertically positioned indexing shafts (102), round discs in the level direction at the indexing discs are provided with a plurality of axial straight grooves in equal internals along the periphery of the round discs; a rotary ring (7) is sleeved to an indexing shaft which is close to the lower part of the indexing disc and between support seats; a shifting fork and correspondingly arranged bolt device, which separately comprises; a handle (1), a shifting fork seat (5), a shifting fork (6), a shifting fork seat cover (4), a bolt (12), a bolt seat (11) and a bolt seat cover (13); the bolt seat is fixed on the support seat and the bolt and the shifting fork can move axially relative to the indexing disc and insert to the straight channel of the indexing disc, which lead to the simple and quick rotation for the processing and the simple structure of the invention.
Description
technical field [0001] The invention relates to standard part processing equipment, in particular to a nut processing equipment. Background technique [0002] Nuts (nuts) are widely used as standard parts in all walks of life. The end faces of the most commonly used hexagonal nuts must be processed into inclined arc surfaces at the hexagonal positions. Therefore, in the production of nuts, the six corners must be sequentially After grinding a corner, the workpiece needs to be rotated 60° to grind the next corner. Existing grinders all work by turning a handle or a certain number of turns of the turntable, and the workpiece holding the nut is turned to the next station. This kind of mechanism involves transmission parts such as gears and chains. The structure is relatively complicated. The number of rotations must be kept in mind. become worse, resulting in a decrease in the dimensional accuracy of the nut. Contents of the invention [0003] The present invention aims to...
