The utility model relates to the field of clamps, and discloses a copper male clamping jig which comprises a base, mounting seats fixed at the four corners of the upper end of the base and adjusting rods installed at the upper ends of the mounting seats in a threaded mode, an inner shell is fixedly arranged at the position, close to the upper end, of the interior of each adjusting rod, and limiting assemblies are installed on the two sides of the interior of each inner shell. And an extrusion assembly used for extruding the two limiting assemblies to move outwards is installed at the position, located at the upper ends of the two limiting assemblies, of the middle point in the inner shell, and top covers are fixedly arranged at the upper ends of the multiple adjusting rods correspondingly. According to the utility model, the multi-station mounting and fixing design can be realized, and meanwhile, the specificity that in the prior art, when bolts are used for fastening, abrasion is easy to occur, and a wrench is needed for disassembly and assembly is avoided.

The locking tool comprises a locking base, a sliding block, a sliding block bolt, an inclined face pressing plate, an arc face pressing plate and a pressing plate bolt, two positioning columns and a boss are arranged on the upper face of the locking base, a sliding groove is formed in the locking base, an opening is formed in the groove wall of the side, close to the positioning columns, of the sliding groove, the sliding block is arranged in the sliding groove, and the pressing plate bolt is arranged on the sliding block. The locking seat is provided with a sliding block jacking screw hole, a screw rod of the sliding block bolt is installed in the sliding block jacking screw hole and jacks the sliding block, the inclined face pressing plate is arranged on the locking seat, the boss is provided with a pressing plate screw hole, and the two ends of the cambered face pressing plate are arranged on the inclined face pressing plate and the boss respectively. And a screw rod of the pressing plate bolt penetrates through a vertical through hole in the middle of the cambered surface pressing plate from top to bottom and then is connected with the pressing plate screw hole. According to the thin-wall fin clamping and locking device, stable and reliable clamping and locking functions can be achieved in the two-side direction and the thickness direction of a thin-wall fin, the thin edge of the thin-wall fin and the whole thin-wall fin are effectively protected, and the overall machining quality, the machining efficiency and the part qualification rate are improved.

The invention relates to the technical field of gear surface grinding machining of aviation air door shaft type and limiting gear shaft type parts, in particular to a flexible inner and outer gear double-tooth-surface grinding device and machining method.The device comprises a manual reversing mechanism, a flexible double-face stress mechanism and a motor driving reciprocating mechanism; the device is high in machining efficiency, good in precision control, stable and reliable in quality and capable of meeting the high-precision machining requirement that the joint fork lugs with the rotation structures are produced in batches and cannot deform.
