Detailed Description

As shown in fig. 1-4, a locking device of a turning clamp includes a first bracket 1 disposed on a turning clamp 12, a second bracket 6 disposed on a turning clamp base 13 and having an arc-shaped sliding hole 8, a sliding base 2 disposed on the first bracket 1, a cylinder block 4 disposed in an inner cavity of the sliding base 2, a piston rod 5 having one end disposed in the cylinder block 14 and the other end connected to the arc-shaped sliding hole 8 of the second bracket 6, a gland 3 connected to one end of the sliding base 2 and having a core portion provided with an adjusting rod 9, a spring 11 disposed in the inner cavity of the sliding base 2 and having one end connected to the piston rod 5 and the other end connected to the adjusting rod 9, locking pads 7 disposed on the piston rod 5 and respectively located at two sides of the second bracket 6, and an oil inlet 10 penetrating through the inner cavity of the cylinder block 4 is further disposed on the gland 13.

Further, the axis of the inner cavity of the sliding seat 2 is concentric with the axis of the oil cylinder body 4.

Further, the axis of the cylinder block 4 is concentric with the axis of the gland 3.

Further, the axis of the gland 3 is concentric with the axis of the adjusting rod 9.

Further, a screw hole 3-1 for screwing connection with the adjusting rod 9 and a counter bore 3-2 adjacent to the screw hole 3-1 for sliding the adjusting rod 9 inside are arranged at the center of the gland 3;
