The invention discloses a differential shell inner spherical surface turning fixture, relates to the field of part machining tools and provides a fixture special for turning of an inner spherical surface of a differential shell. The fixture comprises a differential shell fixing frame, an intermediate supporting plate, a positioning pin, a positioning pin mounting strip, a clamping shaft and a compression structure. The differential shell fixing frame comprises a first end plate, a second end plate and four connecting strips for connecting the first end plate with the second end plate; the first end plate is provided with a bearing mounting outer circle fixing groove; the intermediate supporting plate is located between the first end plate and the second end plate and provided with a semicircular positioning outer circle fixing groove; the positioning pin is located between the first end plate and the intermediate supporting plate; the clamping shaft is perpendicular to the second end plate and is connected to the outer side of the second end plate; the clamping shaft, the bearing outer circle fixing groove and the positioning outer circle fixing groove are coaxially arranged / formed; and the compression structure is connected with a top connecting strip. According to the fixture, it can be guaranteed that turning machining of the inner spherical surface of the differential shell is smoothly conducted, and machining accuracy is guaranteed.
Description
technical field [0001] The invention relates to the field of parts processing tooling, in particular to a spherical surface turning fixture in a differential housing. Background technique [0002] Common automotive differential housings such as Figure 4 As shown, there is a bearing installation outer circle at both ends of the automobile differential housing, and the differential housing also has an installation positioning outer circle concentric with the bearing installation outer circle and two vertically intersecting bearing installation outer circles. The inner side of the planetary gear shaft hole and the differential case has an inner spherical surface, and the center of the inner spherical surface is located at the intersection of the axis of the outer circle of the bearing and the axis of the planetary gear shaft hole. When turning the inner spherical surface, due to the complexity of the differential housing, it is inconvenient to fix, and the requirement for the ...
