Abstract

The invention relates to a plunger assembly, a lubricating pump, a plunger and a plunger machining method. The plunger comprises a large-diameter section and a small-diameter section. The large-diameter section and the small-diameter section are separately arranged and respectively machined. The large-diameter section is formed by turning and machining. The small-diameter section is formed throughmachining by a centerless excircle grinding machine. The large-diameter section and the small-diameter section are connected with each other after being separately machined. According to the plungerassembly, the lubricating pump, the plunger and the plunger machining method, through ingenious conception and simple structures, machining consumables are saved, the machining efficiency is improved,and more importantly, the machining precision of the plunger is improved, so that the pressure bearing capacity of the plunger is further improved, the pressure bearing capacity of the lubricating pump is improved, and a very important significance is embodied.

Description

technical field [0001] The invention relates to a plunger assembly, a lubricating pump, a plunger and a processing method for the plunger. Background technique [0002] The multi-point plunger lubrication pump is the main part of the intelligent centralized lubrication system, mainly including the oil tank and the pump head assembly. The pump head assembly is equipped with a driving device, a cam assembly and a plunger assembly used in conjunction with the cam assembly. The plunger assembly is an independent oil pump unit, which is connected to the oil pipe to lubricate each lubrication point. The plunger assembly includes a plunger housing, and the oil channel of the plunger housing is slidingly equipped with a reciprocating device to suck and push oil. The moving plunger, the sliding seal between the plunger and the oil passage, the plunger includes a small-diameter section that slides with the oil passage and a large-diameter section that cooperates with the cam assembly....
