Detailed Description
The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
A differential mechanism shell inner spherical surface position degree detection tool shown in figures 1-2 comprises a mandrel 1, a detection block 2, a positioning pin 3 and an anti-rotation block 4. The detection block 2 is sleeved at the lower part of the mandrel 1; the positioning pin 3 is arranged below the detection block 2; the anti-rotation block 4 is embedded on the detection block 2, a screw 5 is arranged on the detection block 2 to fix the anti-rotation block 4, and the screw 5 can also pass through the anti-rotation block 4 to be tightly fixed on the mandrel 1; the lower part of the mandrel 1 has a chamfered plane 6 in contact with the anti-rotation block 4, thus preventing the rotation of the positioning pin 3 relative to the mandrel. The upper part of the mandrel 1 is provided with a flange 7, the upper end surface of the flange 7 is vertical to the axis of the mandrel 1, and the roughness of the upper end of the flange 7 is not more than Ra0.8. The upper end of the mandrel 1 is provided with a handle 8, so that the mandrel 1 can be conveniently rotated.
As shown in fig. 2, the using method of the position degree checking fixture is that a differential casing is supported on a positioning platform, a planetary gear shaft hole is kept in a vertical position, a mandrel 1 penetrates through the planetary gear shaft hole at the upper end, a detection block 2 is placed in advance in the casing from a hole on the side face of the differential, a positioning pin 3 is kept downward, the detection block 2 is sleeved on the lower portion of the mandrel 1, a guide cone 9 is arranged at the lower end portion of the mandrel 1 for convenient sleeving, the guide cone 9 and the shaft rod of the mandrel 1 are in smooth transition, and the detection block 2 can rotate along with the mandrel 1 through limiting of a rotation prevention block 4 and a chamfered plane 6. The lower extreme of dabber 1 wears out the planet wheel shaft hole of differential mechanism casing below, and the lower extreme of locating pin 3 contacts with the interior sphere of differential mechanism casing, and in order to make dabber 1 rotate smoothly, and guarantee that interior sphere is not by the fish tail, the lower tip of locating pin 3 is the bulb in this embodiment.
The locating platform is provided with a dial indicator, a measuring rod of the dial indicator is in contact with the upper end face of the flange 7, the mandrel 1 is rotated through the handle 8, and the locating pin 3 is in sliding contact with the inner spherical surface, so that position error can be reflected to the dial indicator.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the description should not be construed as a limitation to the present invention.
