Description

Technical Field

[0002] Oiling machines, as the name suggests, are mainly used to deliver lubricating oil in the lubrication systems of various mechanical equipment. According to different driving methods, oiling machines can be divided into pneumatic oiling machines, hydraulic oiling machines, manual oiling machines and motor-driven oiling machines. The application field of oiling machines is very wide, and they are more commonly used in the mechanical field. During operation, the oiling machine is used to forcibly pressurize lubricating oil into friction parts to reduce wear on machine parts and ensure normal operation of the machine.

[0003] The oiling machine mainly includes an oil pump, an oil barrel, a driving mechanism, an oil pipeline and a control valve. During processing, the oil barrel shell needs to be drilled in order to connect the oil pipeline, seals and valves. Since the oil barrel shell is generally barrel-shaped, it is currently only simply clamped by a clamp during processing, and the clamping tightness is difficult to control. If the clamping is too tight, the oil barrel shell is easy to be damaged. If the clamping force is insufficient, the oil barrel shell is easy to roll and slide, resulting in poor processing accuracy. At the same time, the drilling of oil barrels has different requirements for the drilling position according to different models. The current drilling equipment is difficult to achieve precise drilling with flexible adjustment at different positions. Utility Model Content
