Abstract
Disclosed is a planetary gear carrier drilling process of a planetary gear speed reducer. A planetary gear carrier is provided with an upper layer of carrier plate and a lower layer of carrier plate, wherein the upper layer of carrier plate is provided with an upper through hole, the lower layer of carrier plate is provided with a lower through hole opposite to the upper through hole, and the diameter of the upper through hole and the lower through hole is 3.55 mm. The planetary gear carrier drilling process comprises the following steps that A, a spotting drill is used for abutting against and positioning the upper layer of carrier plate; B, a twist drill with the outer diameter of a drill bit being 3.1 mm is used for drilling out the upper through hole in the upper layer of carrier plate; C, a three-blade milling cutter with the outer diameter of a milling head being 3.4 mm is used for milling the upper through hole; D, a twist drill with the outer diameter of a drill bit being 3.1 mm is used for drilling out the lower through hole in the lower layer of carrier plate; E, a three-blade reamer with the outer diameter of a reaming head being 3.55 mm is used for reaming the upper through hole; F, a four-blade milling cutter with the outer diameter of a milling head being 3.4 mm is used for milling the lower through hole; and G, a four-blade reamer with the outer diameter of a reaming head being 3.55 mm is used for reaming the lower through hole. By means of the method, the concentricity of the upper through hole and the lower through hole is further improved, and the size accuracy of the upper through hole and the lower through hole is further improved.
Description
Technical field
The present invention relates to a kind of pinion frame bore process of planetary reducer.
Background technology
The pinion frame of planetary reducer have upper strata frame plate and lower floor's frame plate, upper strata frame plate is provided with through hole, lower floor's frame plate is provided with the lower through-hole (namely go up through hole with lower through-hole coaxial) relative with upper through hole, generally goes up through hole, the diameter of lower through-hole is 3.55mm.In the prior art, simple bore process is adopted to the processing of upper through hole and lower through-hole, be difficult to the concentricity and the size precision that ensure lower through-hole.
Summary of the invention
In order to overcome the deficiency of the pinion frame bore process of planetary reducer in prior art, the invention provides a kind of pinion frame bore process guaranteeing the concentricity of upper lower through-hole and the planetary reducer of size precision further.
The technical scheme that the present invention solves its technical problem is: a kind of pinion frame bore process of planetary reducer, this pinion frame has upper strata frame plate and lower floor's frame plate, described upper strata frame plate is provided with through hole, described lower floor's frame plate is provided with the lower through-hole relative with described upper through hole, and the diameter of described upper through hole, lower through-hole is 3.55mm;
This technique comprises the following steps:
A. adopt pilot drill that upper strata frame plate is withstood location;
B. fluted drill is adopted on the frame plate of upper strata, to get out through hole, the external diameter of the drill bit of this fluted drill
For 3.1mm;
C. adopt three blade milling cutters to carry out milling to upper through hole, the external diameter of the milling head of this three blade milling cutter is
3.4mm；
D. adopt fluted drill to get out lower through-hole on lower floor's frame plate, the external diameter of the drill bit of this fluted drill is 3.1mm;
