Detailed Description
A novel stroke adjusting mechanism for an oil cylinder of a punch press comprises a cylinder body 12, wherein a cavity is formed in the cylinder body 12, a piston 9 capable of moving relative to the cylinder body 12 is arranged in the cavity, an oil inlet is formed in the lower portion of the cylinder body 12 and communicated with the cavity formed between the cylinder body 12 and the piston 9, and an oil seal 10 and a guide ring 11 are arranged between the outer surface of the piston 9 and the inner surface of the cylinder body 12;
the piston 9 is provided with an adjusting screw rod 1, and is provided with a motor driving device for driving the adjusting screw rod 1 to move up and down, the motor driving device comprises a motor, a worm 17 driven by the motor and a worm wheel 15 driven by the worm 17, and the worm wheel 15 drives the adjusting screw rod 1 to move up and down.
Further, an adjusting pad 8 is arranged between the upper surface of the piston 9 and the lower surface of the adjusting screw rod 1.
Furthermore, a clamping key 7 is arranged on the upper portion of the inner wall of the cylinder body 12, and the clamping key 7 is arranged on a path of the upward movement of the piston 9 to limit the movement of the piston 9.
Further, the worm 17 is supported by a tapered roller bearing 18, and a corresponding bearing cover 19 is disposed on the tapered roller bearing 18.
Further, the worm wheel 15 drives the adjusting screw rod 1 to move up and down through the flat key 14.
Further, the worm wheel 15 is arranged in a worm wheel box 4, the worm wheel box 4 is arranged on the cylinder body 12, a gland 3 is arranged on the worm wheel box 4, and an oil filter screen 5 positioned on the upper portion of the worm wheel 15 is arranged on the gland 3.
