[0004] The technical scheme of the utility model is: a kind of fin punch ball head ball bowl gap detection adjustment device, the device includes ball head, ball head gland, oil cylinder cover plate, piston, oil cylinder, support sleeve, ball bowl, slider piston and slider oil cylinder;

[0005] The oil cylinder cover plate, piston and oil cylinder are combined into an oil cylinder assembly, the oil cylinder assembly is fitted on the ball head, the support sleeve supports the oil cylinder assembly, and the ball head gland is arranged on the upper end surface of the ball head.

[0006] The ball bowl is arranged in the slider piston.

[0007] The ball head gland presses the ball head on the ball bowl surface in the slider oil cylinder.

[0008] Preferably, the ball head gland is a spherical gland.

[0009] Preferably, the ball head and the ball bowl are in spherical surface contact, and the ball head is in a vertical state.

[0010] Preferably, the distance between the lower end surface of the ball head gland and the upper end surface of the piston is less than 5 mm.

[0011] The utility model has the advantages of solving the problem of lock-up caused by too small ball head gap or precision out-of-tolerance caused by too large gap, saving assembly time, ensuring the precision of the whole machine operation, and reducing the cost of assembly adjustment.
