Abstract

The invention relates to an auxiliary device for drilling holes in the outer edge of a shaft and belongs to the technical field of mechanical manufacturing and design. The auxiliary device comprises two hydraulic lifting devices and a positioning sleeve, wherein a plurality of uniformed formed positioning threaded holes are formed in the wall of the positioning sleeve, and hollow bolts are screwed inside the positioning threaded holes; supporting frames for keeping the hydraulic lifting devices stable are arranged on the hydraulic lifting devices, protective barrels are arranged at tops of the supporting frames, the hydraulic lifting devices are sleeved with the protective barrels, bracket plates are arranged on the hydraulic lifting devices, supporting grooves are formed in the bracket plates, and supporting groove covers matched with the supporting grooves in shape are arranged on the supporting grooves and are in hinged connection with the supporting grooves. During specific usage, the shaft is placed on the bracket plates on the two hydraulic lifting devices and sleeved with the positioning sleeve, according to the size of the shaft, the hollow bolts on the positioning sleeve are tightened towards the shaft by the aid of the positioning threaded holes, finally, the shaft is clamped by a plurality of hollow bolts, and drilling equipment penetrates through the holes of the hollow bolts to drill the holes in the shaft.

Description

technical field [0001] The invention relates to an auxiliary device for drilling a shaft outer edge, which belongs to the technical field of mechanical manufacturing design. Background technique [0002] The shaft is a cylindrical object that goes through the middle of the bearing, the middle of the wheel or the middle of the gear. According to the actual production needs, the shaft often needs to be drilled on the outer edge of the shaft. When using drilling, in order to ensure the quality of the drilling and avoid the non-vertical and inclined holes that need to be drilled, it is necessary to ensure that the drilling is level with the ground when drilling. But often difficult. Although some existing professional large-scale drilling equipment can realize accurate drilling of holes, the equipment has a complex structure and is prone to problems, and maintenance after problems occur is relatively cumbersome. Therefore, people are in urgent need of a drilling device or auxi...
