The invention discloses a mould for drilling holes in a worm wheel, and the mould comprises a fixed bottom plate, a rotary bottom plate, a drill mould, a pressure plate and a rotating shaft; the rotating shaft is vertically arranged on the fixed bottom plate; the rotary bottom plate is sleeved on the rotating shaft and is rotationally arranged on the fixed bottom plate through a bearing; the upper end surface of the rotary bottom plate is provided with a boss which is matched with an inner hole of the worm wheel; the drill mould which is matched with a screw hole of the worm wheel is fixedly arranged on the worm wheel through the pressure plate; and the drill mould and the pressure plate are sleeved on the rotating shaft. According to the mould for drilling holes in the worm wheel, the working efficiency can be improved, the labor cost is reduced, the product precision is improved, and the product quality is ensured. The mould for drilling holes in the worm wheel has higher efficiency particularly when a drilling machine operates a work piece which is longer than a drilling boom.
Description
technical field [0001] The invention relates to a mold, in particular to a mold for drilling holes in worm gears. Background technique [0002] In worm gear products, the screw holes are arranged in equal parts with a center as the center. The traditional drilling method of worm gears is: firstly mark the positions on the worm gears that need to be drilled, and then fix the worm gears on the drilling machine. The drill bit is drilled at a marked position, and after the hole is completed, the drill bit is turned to make the drill bit realign to the next marked position, and then the drilling operation is performed, and so on, until all holes are completed. The disadvantages of this method are: low drilling efficiency and inconvenient operation; due to the need to constantly align the position, the accuracy is poor, and defective products are prone to occur. Contents of the invention [0003] In order to overcome the problems existing in the prior art, the object of the p...
