The structure of the core is complex, the processing difficulty is big, the cost is high, and it is usually made of high-precision material to ensure the service life and precision of the die.

[0003] When processing the core of the stamping die, the jig is needed to fix it, but the current jig usually directly contacts the core of the stamping die with hard (usually metal, alloy, etc.) structure, and in the subsequent polishing process, the core of the stamping die may vibrate, which may cause wear with the hard structure, resulting in the decrease of the precision of the core of the stamping die. UTILITY MODEL CONTENT

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a jig for polishing the core of the stamping die, comprising a supporting mechanism and a driving mechanism arranged on the supporting mechanism, the supporting mechanism comprising a workbench and a protective fence fixed on the workbench, a side groove is arranged on the inner end face of the protective fence, a sliding groove is arranged on the upper end face of the workbench, the driving mechanism comprises a motor, a screw rod connected with the output end of the motor, and a sliding seat screwed on the screw rod, the motor is fixed on the protective fence, the sliding seat is attached to the inner wall of the side groove, and the end of the sliding seat away from the screw rod is fixed with a positioning plate, further comprising a positioning mechanism, the positioning mechanism comprising an air pump fixed on the positioning plate, an air pipe connected with the air pump, and a suction cup matched with the air pipe, the suction cup is fixed on the positioning plate.

[0006] Preferably, the screw rod is horizontally arranged in the side groove, and the screw rod is rotatably connected with the protective fence, so that the screw rod can stably operate.

[0007] Preferably, an extension seat is arranged on the lower end face of the positioning plate, the extension seat is slidingly arranged in the sliding groove, and the extension seat is attached to the inner wall of the sliding groove; so that the positioning plate drives the extension seat to translate in the sliding groove when moving.

[0008] Preferably, a spring is arranged on the outer side of the sliding seat, and the two ends of the spring are fixedly connected with the protective fence and the positioning plate respectively.

[0009] Preferably, an inner pipeline is arranged in the interior of the positioning plate, and the air pipe is communicated with the suction cup through the inner pipeline.

[0010] Preferably, the air pump and the air pipe are both installed on the upper end surface of the positioning plate, so that the air pump and the air pipe are kept stable in structure.

[0011] Preferably, the driving mechanism and the positioning mechanism are both provided in multiple groups, one group of the driving mechanism corresponds to one group of the positioning mechanism, and the multiple groups of the positioning mechanism are distributed in a circumferential array along the vertical central axis of the supporting mechanism.

[0012] Compared with the prior art, the utility model has the advantages that before polishing the stamping die core, the positioning mechanism is contacted with the stamping die core, and the inner side space of the suction cup is vacuumized by the air pump and the suction cup, so that the stamping die core is firmly adsorbed by the suction cup, thereby ensuring that the stamping die core is kept stable in structure during polishing. The stamping die core is fixed by the soft suction cup, so that the stamping die core is not pressed by the hard structure, thereby avoiding abrasion of the stamping die core due to vibration during polishing, and ensuring the precision of the stamping die core.
