The outer side of each elastic clamping block 14 is provided with an outer conical surface 1401 that matches the inner conical surface 8001 of the machine tool spindle 8000. The clamp body 1 is also connected with a locking member 15 for locking the clamp body 1 onto the machine tool spindle 8000. This utility model discloses an auxiliary fixture for machining oblique circular holes on steel pipes. In use, the steel pipe is first inserted into the oblique positioning circular hole on the first positioning block. Then, the position of the steel pipe relative to the fixture body is adjusted by the adjustment mechanism. Then, the locking element pulls the fixture body. The outer conical surface of the elastic clamping block cooperates with the inner conical surface of the machine tool spindle, causing the two elastic clamping blocks to retract inward, thereby quickly locking the steel pipe.

[0026] In this embodiment, the adjusting frame 131 is provided with an adjusting part 1311 that is parallel to the end face of the steel pipe 1000. The threaded hole is connected to the adjusting part 1311. The parallelism between the adjusting part 1311 and the end face of the steel pipe 1000 can improve the accuracy of the steel pipe position adjustment.
