Detailed Description
The embodiments of the present invention will be described with reference to the accompanying drawings.
Referring to fig. 1, the turning clamp for the round tube of the crystallizer copper tube blank comprises a supporting tube body 1 with a flange at the rear end, wherein the supporting tube body 1 is a round-section tube and is coaxially connected to the front end of a lathe spindle through the flange, and during specific implementation, the supporting tube body 1 is fixedly connected with a lathe chuck base plate through the flange. The front part of the supporting tube body 1 is provided with a pair of axial long holes 2 which penetrate through in the radial direction, and the axial long holes 2 are long round holes. The supporting pipe body 1 is internally and coaxially penetrated with a push-pull rod 3 with a circular section, the rear end of the push-pull rod 3 is coaxially connected with a piston rod of a cylinder arranged on a lathe spindle box through a rotatable connecting joint, and the rotatable connecting joint can realize the free rotation of the push-pull rod 3 while realizing the coaxial connection of the push-pull rod 3 and the piston rod of the cylinder. The rear part of the supporting pipe body 1 is provided with a rear conical surface sleeve 4, the front part of the supporting pipe body 1 is provided with a front conical surface sleeve 5, the outer diameter surfaces of the rear conical surface sleeve 4 and the front conical surface sleeve 5 are surfaces combining a cylindrical surface and a conical surface, and the conical surfaces of the rear conical surface sleeve 4 and the front conical surface sleeve 5 are arranged oppositely. The rear conical surface sleeve 4 is fixedly arranged on the supporting pipe body 1 through screws 6 distributed along the circumferential direction, and the front conical surface sleeve 5 is connected with a bolt 7 penetrating through the axial long hole 2 and the push-pull rod 3 and is arranged on the supporting pipe body 1 in a sliding fit manner. And expansion sleeves 8 are arranged outside the rear conical surface sleeve 4 and the front conical surface sleeve 5, and the expansion sleeves 8 are made of spring steel. The two ends of the expansion sleeve 8 are respectively provided with conical surface holes matched with the conical surface of the rear conical surface sleeve 4 and the conical surface of the front conical surface sleeve 5, the two ends of the expansion sleeve 8 are respectively provided with cylindrical surfaces matched with the inner diameter of a processed blank circular tube 10, the two ends of the expansion sleeve 8 are respectively provided with expansion grooves 9 uniformly distributed along the circumference, the axial length of each expansion groove 9 at each end is greater than one half of the axial length of the expansion sleeve 8, and the expansion grooves 9 at the two ends are arranged in a staggered mode in the circumferential direction.
When the turning clamp for the blank circular tube of the crystallizer copper tube is used, the blank circular tube 10 to be machined is sleeved outside the expansion sleeve 8, the cylinder is started to enable the piston rod to move backwards, the push-pull rod 3 drives the front conical surface sleeve 5 to move backwards through the bolt 7, the rear conical surface sleeve 4 and the front conical surface sleeve 5 force the working cylindrical surface of the expansion sleeve 8 to be tightly matched with the inner diameter surface of the blank circular tube 10 to be machined, locking of the blank circular tube 10 is achieved, and the outer diameter of the blank circular tube 10 to be turned by a lathe is started. After cutting, the cylinder is started to enable the piston rod to move forwards, the push-pull rod 3 drives the front conical surface sleeve 5 to move forwards through the bolt 7, locking of the working cylinder surface of the expansion sleeve 8 on the processed blank circular tube is released, the processed blank circular tube is removed, and then turning of the next blank circular tube is carried out.
