[0015] The following combines the drawings to specifically describe the present utility model. As shown in the attached Figure 1 figures, an automatic fixing fixture for machining of a machine tool includes a fixture seat 1. A motor 2 is drivingly installed at the middle part of the lower part of the fixture seat 1. Slide grooves 3 are arranged in the fixture seat 1 in a divergent manner with the center of the fixture seat 1 as the center to the outside. A clamping block 4 is slidably arranged on the upper part of each slide groove 3. The clamping block 4 is fixed to the fixture seat 1 by bolts and nuts. A central column assembly 5 is fixedly installed at the center of the upper part of the fixture seat 1.

[0016] In this implementation manner, as shown in the attached Figure 2 figures, the central column assembly 5 includes a fixed pipe 51. An internal thread is provided inside the upper end of the fixed pipe 51. A stud 52 is installed at the upper end of the fixed pipe 51 through the internal thread. A connecting column 53 is arranged at the lower end of the stud 52. Through grooves 54 are opened on both sides of the fixed pipe 51. V-shaped rods 55 are arranged on both sides of the fixed pipe 51. The V-shaped rod 55 is formed by pin-connected two steel rods in a V shape. The upper end of the upper V-shaped rod 55 is pin-connected to the connecting column 53, and the lower end of the lower V-shaped rod 55 is pin-connected to the fixed pipe 51. A cylindrical workpiece is sleeved outside the fixed pipe 51. The stud 52 is rotated, so that the stud 52 drives the connecting column 53 to move downward, thereby pressing down the V-shaped rod 55, and the outside of the V-shaped rod 55 presses against the inside of the cylindrical workpiece, making the workpiece more firmly fixed.
