Technical Field

The invention relates to the technical field of machining, in particular to a process for machining oil groove parts by utilizing a macro program.

Background

With the increasing requirements on the functions of mechanical structures, high requirements are also put on the structures and relative movement relationships of some parts, so that relative movement of a plurality of shaft or shaft sleeve parts is required, and oil grooves for storing and distributing lubricating oil are required on the relative movement surfaces of the relative movement parts, so that a uniform oil film is formed on the movement surfaces to reduce friction. The distribution and shape of the oil grooves directly affect the formation of an oil film and finally affect the running quality of parts. Currently, common oil grooves include an open oil groove having annular grooves (undercut grooves) at both ends or one end; a closed oil groove, which has no oil groove with annular grooves (clearance grooves) at both ends; closing an oil groove through the hole, wherein one of two cross points of the oil groove is provided with an oil inlet hole to be sleeved; the oil grooves are additionally arranged in inner holes of a plurality of shaft sleeve parts on engineering machinery and are often 8-shaped or double 8-shaped closed oil grooves, the existing machining single oil groove can be removed by an oil groove chisel after being scribed by a bench worker, but the machining mode has the disadvantages of high labor intensity, low efficiency and low precision; the batch processing needs to use a special machine tool for turning, the processing mode has high efficiency, but needs special manual machine turning operation, and has high processing cost; when the commonly used economic numerically controlled lathe is used for processing the parts, the spiral groove part of the shaft sleeve is easy to be turned on, the parts are easy to deform, the use performance of the parts is affected, and particularly, the parts are easy to leak oil or have point friction with the shaft, so that the product percent of pass is low, and the conventional economic numerically controlled lathe is not suitable for processing 8-shaped or double 8-shaped closed oil grooves.
