Method for grinding the inner spherical surface of the ball cage bell shell and fine milling the inner ballway of the ball cage bell shell

Abstract

The invention provides methods for grinding of inner ball surfaces of ball cage bell housings and finish milling of inner ball passages of the ball cage bell housings. According to the methods, a fixing component, a grinding shell inner ball surface component and a finish milling ball passage component are involved. The fixing component comprises a clamping part, a first lower base, a first driving device and a fourth driving device, and the fourth driving device drives the clamping part to self-rotate around the central axis of the clamping shaft. The grinding shell inner ball surface component comprises a grinding clamp and a first guiding rail, and the finish milling ball passage component comprises a finish milling clamp and a second guiding rail. According to the first specific method, a grinding block on the grinding clamp moves on the guiding rail in a reciprocating mode to grind the inner ball surfaces and to finish-mill the inner ball passages, and according to the second specific method, the grinding block moves leftward and rightwards in a reciprocating mode in the direction perpendicular to the guiding rail to grind the inner ball surfaces and to finish-mill the inner ball passages. The method for grinding of the inner ball surfaces of the ball cage bell housings and finish milling of the inner ball passages of the ball cage bell housings has the advantages that only one fixing component is needed for two tools for grinding of the inner wall surfaces and finish milling of the inner ball passages, and through the two specific methods, the different inner ball surfaces can be grinded, and the different inner ball passages can be subjected to finish milling.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a method for grinding the inner spherical surface of a ball cage bell-shaped shell and fine-milling the inner ballway of the ball cage bell-shaped shell. Background technique [0002] The ball cage bell housing is an important part in the transmission system of the car. Its function is to transmit the power of the engine from the transmission to the two front wheels to drive the car to run at high speed. The outer ball cage is to fix the steel balls in the six windows of a cage between the star-shaped sleeve and the bell-shaped shell. The steel balls are in the star-shaped sleeve and the bell-shaped shell. Half of the positions are used for driving at one time. The smooth surface treatment makes the motion of the universal joint look like a helical gear. The six steel balls respectively push the star-shaped sleeve and the ballway in the bell-shaped housing respectively, and car...
