[0002] In production, it is often necessary to process positioning pin holes on gears for positioning during gear installation; however, in the production workshop, when processing larger gears, because the gears are very heavy, tools such as cranes in the workshop are often used When hoisting the gear to the machine tool, since the upper end of the machine tool is often hung on the cable of the crane, it is inconvenient to set the gear in this way, and the number of positioning pins that need to be processed on the gear is large, and each positioning pin hole needs to be cooperated with the crane Rotate the gear, so not only the positioning accuracy is poor, but also the production efficiency is particularly low

Embodiment 1
[0038] As shown in the accompanying drawings, a drilling method controlled by gear positioning pins in this patent includes the following steps:
[0039] Step 1: Set a horizontal slide rail 1 outside the drilling machine, and the horizontal slide rail 1 extends to the bottom of the drilling machine.
[0040] Step 2: Install a positioning trolley 2 on the horizontal slide rail 1, the positioning trolley 2 includes a frame body 5 and four traveling wheels 6; the outer edge of the frame body 5 is provided with a recess 7; the traveling wheels 6 are arranged under the frame body 5 Or the outside is used to support the frame body 5; the traveling wheels 6 are arranged on the horizontal slide rail 1 and can move on the horizontal slide rail 1; the positioning trolley 2 can move along the horizontal slide rail 1 to the bottom of the drilling machine.
[0041] Step 3: Install a supporting device 3 on the positioning trolley 2, the supporting device 3 includes a fixed plate 8, a rotati...

The invention discloses a drilling method for a gear locating pin hole. The drilling method can be matched with a drill machine tool very conveniently to machine the locating pin hole for a gear. The gear does not need to be moved again after locating, the machining precision of the locating pin hole is improved, the production efficiency can be improved, and the production cost is reduced. According to the drilling method, a locating trolley is arranged, thus the beneficial effect of convenient locating is achieved, the locating trolley can move out of the range of the drill machine tool, thus lifting of the gear through an overhead crane is facilitated, and obstruction of the drill machine tool to a cable of the overhead crane is avoided. In addition, according to the drilling method, an anti-rotation device is arranged, thus the gear does not rotate during machining of the locating pin hole, and the machining precision of the locating pin hole is further improved.
