Abstract

The invention discloses a tooling and a method for processing the inner spherical surface of a differential case by using the tooling, and relates to the field of machining, including a clamping body. A first fixing plate and a second fixing plate are fixed parallel to the front end of the clamping body. The first fixing plate The plate is provided with a first fixing groove for installing workpieces, and the second mounting plate is provided with a second fixing groove for installing workpieces. Both the front ends of the first fixing plate and the second fixing plate are equipped with fastening devices for fixing workpieces. The angle between the first fixed plate, the second fixed plate and the horizontal plane is 15°. The present invention breaks the conventional way of clamping horizontally, flatly and vertically, and places the spherical surface of the workpiece on the second fixing plate through the two first fixing plates and the second fixing plate which are 15° to the horizontal plane on the CNC lathe , and fix the workpiece on the first fixed plate and the second fixed plate through the pressure plate, screw and nut, and then use the universal inner hole turning tool bar to enter the tool from the window, and use the interpolation movement to process the entire spherical surface at one time.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a tool and a method for processing the inner spherical surface of a differential case by using the tool. Background technique [0002] There is a special-shaped differential housing with an inner cavity of SΦ92.1 full spherical surface. Through analysis, it is impossible to process this spherical surface with current conventional methods, and then jointly research with several CNC processing equipment manufacturers and tool suppliers to design a variety of processing Solutions, such as using special equipment, non-standard forming knives and other solutions, these methods have some disadvantages, 1. The spherical surface cannot be processed at one time. 2. There are risks in large investment in equipment. 3. The shape and position tolerance of the product is not easy to guarantee. Therefore, a tool that can directly process the special-shaped differential case is needed. Co...
