Abstract

The invention discloses a pump body steel ball pressing fitting machine. The pump body steel ball pressing fitting machine is of a vertical structure, and is composed of a machine tool table, a steel ball automatic feeding device, a pressing fitting device and an oil pump clamp. Pressing fitting is driven through a servo motor so that it can be guaranteed that the pump body steel ball pressing fitting machine has the good accuracy, the good rigidity and the good operation stability. A pressure sensor is installed on a pressing head, and changes of displacement and pressure in the pressing fitting process can be monitored in real time. One-face-two-pin positioning is adopted in the clamp, and clamping through an air cylinder is achieved. Pressing fitting process automation is achieved, automatic feeding of a steel ball is achieved through the steel ball automatic feeding device, and the labor production rate is improved.

Description

technical field [0001] The invention belongs to assembly equipment, and is especially suitable for automatic press assembly of steel balls in oil pump bodies. Background technique [0002] The oil pump is an important component in the automobile lubrication system. Its function is to increase the oil to a certain pressure, and then forcefully press it to the moving surfaces of the various parts of the engine. A pressure limiting valve is installed on the pump body. The pressure limiting valve is a steel ball type. When the oil pressure at the outlet of the oil pump reaches a certain pressure value, the pressure acting on the steel ball overcomes the spring thrust of the pressure limiting valve, and the steel ball is pushed away. A part of lubricating oil flows directly back to the oil pan through the oil return pipe. Most of the steel balls in the existing oil pump body are manually operated, which has the problems of low efficiency and unreliable installation. Contents o...
