Claims

[Scope of utility model registration request]

A clamp claw 4 is provided at the front of the clamp body 3, and a spring return type single-acting cylinder 5 is provided at the rear thereof. The spring return type single-acting cylinder 5 is pivoted so as to be able to swing forward and backward through A cylindrical piston rod 2 is connected from the piston 14 to the piston 14 for forward movement.
0 protrudes forward, and the output part 21 at the tip of the piston rod 20 is connected to the force point part 2 at the back of the clamp claw 4.
2, the return spring 18 is inserted into the cylindrical hole 23 of the piston rod 20, the rear end of the return spring 18 is received by the rear end wall 23a of the cylindrical hole 23, and the front end of the spring is received by the spring receiver. The spring receiving pin 25 is received by the abdomen 26 of the pin 25, and is inserted across the clamp body 3, the piston rod 20, and the cylindrical hole 23 and into a pair of pin support holes 28, 28 formed in the clamp body 3. The piston rod 20 is supported on both sides, and a floating groove 30 is formed in the front and back direction to avoid interference with the spring receiving pin 25, and fixing bolt insertion holes 38, 3 are provided in the front and rear parts of the clamp body 3.
In the spring return type single-acting cylinder-driven clamp pawl swing type hydraulic clamp constructed by vertically penetrating the clamp body 9, a pair of pin support holes 28, 28 are formed vertically in the upper wall 3a and lower wall 3b of the clamp body 3. By passing the floating groove 30 vertically through the upper circumferential wall portion 20a and the lower circumferential wall portion 20b of the cylindrical piston rod 20, the spring receiving pin 25 is disposed in the vertical direction. A spring return type single-acting cylinder-driven clamp claw swing type hydraulic clamp characterized by having front fixing bolt insertion holes 38 located on both lateral sides of the clamp.
