Abstract

The invention relates to the technical field of sphere machining equipment, and discloses a clamping mechanism used during machining of a bolt sphere reference surface. The clamping mechanism comprises a mounting base, wherein a fixing sleeve is fixedly arranged inside the left side of the mounting base, the inside of the fixing sleeve is movably connected with a locking nut in a sleeving mode, the fixing sleeve is in transmission connection with the locking nut through an adjusting mechanism, a locking screw rod is in threaded connection with the inside of the locking nut, a fixed pressing plate is arranged at the right end of the locking screw rod, and the inside of the right side of the mounting base is movably connected with an adjusting sleeve in a sleeving mode. According to the clamping mechanism used during machining of the bolt sphere reference surface, through the arrangement of a three-claw pressure rod, the pressure can be simultaneously applied to one side of a bolt spherefrom three directions, and with the cooperation of the extrusion by the fixed pressure plate, the bolt sphere can be stably and effectively fixed at a certain position, the problem of rolling or tilting due to cutting stress is avoided, and the stability and the reliability of the clamping mechanism are effectively improved.

Description

technical field

[0001] The invention relates to the technical field of sphere processing equipment, in particular to a clamping mechanism for processing a bolt ball datum plane. Background technique

[0002] Bolt ball is a grid structure with multiple holes containing internal threads on the sphere to connect multiple connecting rods at one point. Cutting processing, processing and forming of threaded holes, etc., where the datum plane is used as the processing standard of the threaded hole, which can directly affect the processing accuracy of the threaded hole.

[0003] Moreover, the datum planes of the bolt balls are usually arranged in two groups and symmetrically (such as figure 1 shown), in order to avoid the influence of the fixed fixture on the cutting tool when cutting the threaded hole. At present, when cutting the datum plane of the bolt ball, the method of fixing the three-jaw chuck is adopted, but due to The bolt ball is a spherical structure, which makes it po...
