Abstract

The application belongs to the field of columnar part assembly, and particularly relates to a tool clamp for columnar part assembly, which comprises a supporting structure, a clamping structure and a supporting structure; the clamping structure comprises a positioning base arranged on the supporting structure and a linear pressing assembly, the positioning base can stably accommodate and support the columnar part to ensure that the part remains stable during assembly, and the linear pressing assembly is used for applying pressure and clamping and fixing the columnar part in cooperation with the positioning base; the design of the sliding rail ensures that the movement direction of the linear pressing assembly is consistent with the central surface of the positioning base, thereby realizing axial centering clamping and reducing stress concentration caused by eccentric clamping, so that, through axial limiting of the positioning base and the movable supporting piece and in combination with uniform pressure of the linear pressing assembly, the gap problem of the gap frame and the tiger table clamp can be effectively eliminated, the part can be prevented from shaking during assembly, and the clamping stability can be significantly improved.
