[0047] The pressing block 180 is provided with a through hole matched with the angular positioning arm 170 , and the angular positioning arm 170 at the same side passes through the through hole of the pressing block 180 .

[0048] The method for using a novel lathe automatic fixture provided by the embodiment of the utility model is as follows:

[0049] 1. Figure 4-5 As shown; the worker places the automobile exhaust end cone 200 between the two clamping blocks 180, and inserts the small port 230 of the automobile exhaust end cone 200 into the circular boss 160 for preliminary positioning;

[0050] 2. The hydraulic cylinder works, pulling the connecting column 120 to move downward, and the connecting column 120 moves downward to drive the angular positioning arm 170 to move downward; the two pressing blocks 180 on the two angular positioning arms 170 move toward each other and clamp on the outer side of the flange 200a of the small port 230 to complete the clamping and fixing operation;

[0051] 3. After the machining operation of the large port 220 is completed, the hydraulic cylinder works again to push the connecting column 120 upward, causing the two clamping blocks 180 on the two angular positioning arms 170 to move in the opposite direction, thereby releasing the clamping and positioning operation of the automobile exhaust end cone 200.

[0052] In this embodiment, a vertical limiting notch 180 a is provided on the inner side of the pressing block 180 along the side of the pressing block 180 ; the limiting notch 180 a facilitates better pressing of the flange 200 a of the small port 230 .

[0053] In this embodiment, an auxiliary positioning mechanism is also included, and the auxiliary positioning mechanism includes two sets of auxiliary positioning members, and the two sets of auxiliary positioning members are located on both sides of the circular boss 160;
