Abstract
The utility model discloses a gear lapping clamp for an axle drive bevel gear, which comprises a locating holder, wherein the locating holder is used for clamping and locating a workpiece, the locating holder comprises a cylindrical fixed part and a movable part arranged in the fixed part, the fixed part can be fixedly arranged on a work table of a gear lapping machine, the movable part can be connected to a pull rod of the work table of the gear lapping machine, and the movable part is matched with an outer circle of a shaft part of the workpiece under the pull action of the pull rod to automatically clamp and locate the workpiece. Gear lapping belongs to gear finishing processing. The work principles of the gear lapping are basically the same with those of gear shaving and gear honing. Two gear surfaces produce relative sliding motion when being freely meshed without a side clearance after slight braking. When a lapping agent is filled between the gear surfaces, a relative lapping function is performed. Special equipment and the gear lapping clamp are needed during the gear lapping processing. The gear lapping clamp for the axle drive bevel gear has the advantages of high locating precision and high assembling and clamping speed and is favorable to the improvement of the processing quality and efficiency.
