Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The purpose of the present invention is to provide a positioning drilling tool for processing a speed regulator housing, which can assist workers in locating the hole position and complete the drilling processing procedure.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 to Figure 2As shown, this embodiment provides a positioning drilling tool for processing a speed regulator housing, including: a drilling template body 3 and a base plate 1, the base plate 1 is used to ensure stability during drilling, the drilling template body 3 is located above the base plate 1, and the lower surface of the drilling template body 3 is provided with a groove matching the upper surface shape of the upper half of the housing, the drilling template body 3 and the base plate 1 are connected by a positioning shaft, a first positioning structure 13 is provided on the base plate 1, a second bushing is provided between the first positioning structure 13 and the base plate 1, a second positioning structure 9 is provided on the drilling template body 3, a third bushing 8 is provided between the second positioning structure 9 and the drilling template body 3, the first positioning structure 13 and the second positioning structure 9 are both diamond pins, and a drill sleeve 7 is also provided on the drilling template body 3 to facilitate workers to locate the hole position when drilling.

[0025] Specifically, in this embodiment, the positioning shaft passes through the shell, and a third positioning structure 2 and a fourth positioning structure are provided on the positioning shaft. The third positioning structure 2 and the fourth positioning structure cooperate with the inner hole of the shell to complete partial positioning. The third positioning structure 2 and the fourth positioning structure are both cylindrical pins. The third positioning structure 2 is located on the base plate 1 and is detachably connected to the base plate 1 by a set screw 10. The fourth positioning structure is located on the drilling template 3.

[0026] In this embodiment, the positioning shaft and the drilling template body 3 are detachably connected, a fourth bushing 11 is arranged between the positioning shaft and the drilling template body 3, and the upper end of the positioning shaft is threadedly connected to the nut 5, and the drilling template body 3 is limited by the nut 5.

[0027] In this embodiment, the drill sleeve 7 is detachably connected to the drill template body 3. The drill sleeve 7 is a standard quick-change drill sleeve. A first bushing 6 is arranged between the drill sleeve 7 and the drill template body 3. The drill sleeve 7 is detachably connected to the first bushing 6 by a lateral screw 12. When the drill sleeve 7 is worn, the screw 12 is removed to replace the drill sleeve 7.
