Detailed Description
Example 1
As shown in fig. 1-4, a clamping device for processing a thin-wall pipe fitting comprises a clamping part 1, wherein a locking part 2 is arranged on one side of the clamping part 1, at least one through groove 201 is arranged on the periphery side of the locking part 2, locking blocks 4 are arranged on two sides of the through groove 201, and the locking blocks 4 are connected through bolts;
the thin-wall pipe fitting 3 is abutted against the clamping part 1 and the locking part 2, and the inner wall of the locking part 2 is contracted and abutted against the thin-wall pipe fitting 3 by screwing the bolt. With the structure, the thin-wall pipe fitting 3 is sleeved in the clamping part 1 and the locking part 2, and the locking part 2 can be contracted by screwing the bolts to tightly hold and fix the thin-wall pipe fitting 3. Therefore, when the machine tool is clamped, the clamping force of the chuck jaws directly acts on the locking part 2, so that deformation caused by the fact that the machine tool chuck directly clamps the outer surface of the thin-wall part can be avoided.
In the preferred scheme, the inner diameter and the outer diameter of the clamping part 1 and the locking part 2 are in step type, the outer diameter of the clamping part 1 is larger than the outer diameter of the locking part 2, and the inner diameter of the clamping part 1 is smaller than the inner diameter of the locking part 2. With the structure, the joint of the inner diameter steps of the clamping part 1 and the locking part 2 is provided with the conical surface guide, so that the thin-wall pipe fitting 3 can be conveniently introduced into the clamping part 1.
In the preferred scheme, the inner wall of clamping part 1 is laminated on the outer wall of thin-walled pipe fitting 3, and the internal diameter of locking part 2 is slightly greater than the external diameter of thin-walled pipe fitting 3. With the structure, the inner wall of the clamping part 1 is jointed and penetrated with the outer wall of the thin-wall pipe fitting 3, so that the deformation of the thin-wall pipe fitting 3 can be avoided during clamping. When the locking portion 2 is compressed and contracted by the bolt, a locking force uniformly distributed in the circumferential direction is applied to the thin-walled tube member 3.
