With the arrangement of the bevel gear 6 and the second bevel gear 11, multiple moving screws 9 can be rotated simultaneously, so that the positioning plate 10 can be displaced to clamp and position the worm wheel. When drilling is required at the rotated position of the positioned worm wheel, start the first motor 3 to drive the toothed ring 16 to rotate, so that the processing table 7 can be rotated, which is convenient for rotating the positioned worm wheel and convenient for the drilling equipment to drill other positions of the positioned worm wheel.

A placement hole is opened on the side of the vertical plate 17, a limit bearing 18 is arranged in the placement hole, one end of the moving screw 9 is fixedly connected to the inner ring surface of the limit bearing 18, the second bevel gear 11 and the bevel gear 6 are meshed and transmitted with each other. The positioning plate 10 is integrally in a "T"-shaped plate structure. Multiple groups of chutes 8 are arranged, and the multiple groups of chutes 8 are regularly arranged in a circular shape around the center point of the surface of the processing table 7. A vertical plate 17 is arranged in the chute 8.

When it is necessary to drill the rotated position of the positioned worm gear, start the first motor 3 to drive the toothed ring 16 to rotate, so that the processing table 7 can be rotated, which is convenient to rotate the positioned worm gear and convenient for the drilling device to drill other positions of the positioned worm gear. This avoids the situation that when generally positioning a worm gear, a three-jaw chuck is mainly used for positioning. However, the three-jaw chuck is relatively fixed. When the worm gear is positioned and it is necessary to drill other positions on the surface of the worm gear, it is also necessary to loosen the three-jaw chuck to rotate the worm gear by an angle, and then use the three-jaw chuck to position and drill the rotated worm gear, which not only increases the labor intensity of the staff but also reduces the processing efficiency of the worm gear.
