Clamp of milling machine for quickly positioning and clamping workpiece

Abstract

The invention belongs to the field of clamps, and particularly relates to a clamp of a milling machine for quickly positioning and clamping a workpiece. Auxiliary mechanisms are symmetrically arranged at two ends of a clamping block, wherein the left end of the clamping block is movably connected with the right ends of the auxiliary mechanisms; a control block is arranged below the auxiliary mechanisms, and the interior of the control block is fixedly connected with the bottom of the clamping block; a contraction ring is arranged in the clamping block; the inner wall of the clamping block is fixedly connected with the outer surface of the contraction ring; telescopic columns are symmetrically arranged at two ends of the contraction ring, and the left end of the contraction ring is fixedly connected with the right ends of the telescopic columns; the control block comprises a shell, hydraulic columns are evenly arranged in the shell, and the inner wall of the shell is fixedly connected with the bottom ends of the hydraulic columns; and a connecting column is arranged at the top ends of the hydraulic columns, the top ends of the hydraulic columns are fixedly connected with the bottom end of the connecting column, and the top end of the connecting column is fixedly connected with the bottom of the clamping block.

Description

technical field [0001] The invention belongs to the field of fixtures, in particular to a fixture for quickly positioning and clamping workpieces for milling machines. Background technique [0002] During milling machine processing, the workpiece will be affected by cutting force, centrifugal force, inertial force and gravity. In order to ensure that under the action of these external forces, the workpiece can still be processed by the positioning element in the fixture without vibration and displacement. Therefore, certain clamping devices must be set in the fixture structure to clamp the workpiece reliably. [0003] However, the existing milling machines generally use three-jaw chucks for clamping and positioning. The three-jaw chucks need to continue to fix and clamp the two ends of the workpiece with a long length, which wastes working time. The position has specific requirements, and only the edge of the workpiece can be clamped. First, a fixture for quickly positionin...

Problems solved by technology

[0003] However, the existing milling machines generally use three-jaw chucks for clamping and positioning. The three-jaw chucks need to continue to fix and clamp the two ends of the workpiece with a long length, which wastes working time. The part has specific requirements, and only the edge of the workpiece can be clamped. First, a fixture for quickly positioning and clamping the workpiece for a milling machine is proposed to solve the above-mentioned problems.
