Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The utility model will be further explained with reference to the drawings.

Referring to fig. 1-3, a jig for finish-turning a spline housing includes: base 1 and slide 12, base 1 top outer wall welded connection has support wall 2, supports machined part 11, and support wall 2 outer wall one side screwed connection has chuck 3, provides the installation environment who props seat 7, and base 1 top outer wall sliding connection has calibration table 14, supplementary calibration machined part 11.
