[0026] like Figure 1 As shown, this embodiment provides a universal turning fixture for a commercial vehicle chassis steering bracket lathe, including a fixed base 1. The top surface of the fixed base is provided with a left front positioning surface 2, a right front positioning surface 3, a first middle rear positioning surface 4, and a second middle rear positioning surface 5. Several locking bolts 6 are screwed onto the left and right front positioning surfaces. A downward clamping assembly is provided on the first and second middle rear positioning surfaces. A positioning pin 7 is provided in the middle of the top surface of the fixed base.

[0027] In this embodiment of the utility model, the top surface of the fixed base is screwed with a left front positioning block 8 and a right front positioning block 9. The left front positioning surface is located at the top surface of the left front positioning block, and the right front positioning surface is located at the top surface of the right front positioning block.

[0028] In this embodiment of the utility model, the positioning pin is axially vertical and its bottom end is screwed to the top surface of the fixed base.

[0029] In this embodiment of the invention, the first middle and rear positioning surface is located in front of the second middle and rear positioning surface.
