[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A roller shoulder hole machining and positioning device comprises a machining table, wherein the top wall of the machining table is provided with symmetrically distributed first slide grooves, the top wall of the machining table is also provided with symmetrically distributed second slide grooves, and further comprises:
