Manufacturing method for oil pump oil nozzle plunger sleeve

Abstract

The invention provides a manufacturing method for an oil pump oil nozzle plunger sleeve and relates to the technical field of oil pump oil nozzle plunger sleeve production. The manufacturing method for the oil pump oil nozzle plunger sleeve comprises the following steps that (1) a workpiece is located on a lathe, the head of the workpiece is leveled, the end faces of a blank is lathed flat, the total length is determined; the center is determined and a drill bit is aligned to the center of the blank; a hole is drilled and the center hole is drilled in a penetrating mode; the center hole is reamed roughly and precisely; (2) an outer circle is lathed: a step is lathed, an angle is chamfered and a groove is formed; (3) an oil return hole is drilled; (4) a key groove, a ring groove and a straight groove are machined. Due to the fact that the blank is not taken off after rough reaming, the blank is precisely reamed directly, then the outer circle is lathed, head leveling, center determining, hole drilling, rough reaming, precise reaming of the center hole of the plunger sleeve are formed at a time, and meanwhile, secondary clamping of the workpiece is avoided, so that the quality of the product is guaranteed, work time and work procedure are shortened, the labor intensity of operators is reduced, production cost is effectively reduced, and production quality and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of production of oil pump nozzle plunger sleeves. Background technique [0002] The processing steps of the existing oil pump nozzle plunger sleeve: the first step is to flatten the end face of the blank, and the total length is fixed; then center, align the drill bit with the center of the blank; The center hole is opened; then the center hole is roughly reamed; the second step is to remove the workpiece, and the second clamping is performed, and the outer circle is turned; the third step is fine reaming. After rough reaming, it is necessary to remove the rough material and carry out fine reaming on the outer circle of the car. This processing method has the following defects: 1. The second clamping affects the concentricity and smoothness of the workpiece, resulting in low precision. 2. The labor intensity of the workers is high. 3. There are many processes. 4. High cost.
