Clamping device of numerical control machine tool

Abstract

The invention discloses a clamping device of a numerical control machine tool. The clamping device of the numerical control machine tool is larger in moving range, capable of clamping multiple workpieces at a time and performing machining in turn, and higher in working efficiency. The clamping device comprises a first base, a first moving plate is arranged on the first base in a sliding fit manner, a first lead screw is arranged in the first moving plate in a thread fit manner, and the first lead screw is connected with a first driving motor on the first base; a second base is fixed to the first moving plate, a second moving plate is arranged on the second base in a sliding fit manner, and a second lead screw is arranged in the second moving plate in a thread fit manner; the second lead screw is connected with a second driving motor on the second base, a mounting seat is arranged on the second moving plate, and the mounting seat is longitudinally parallel to a second guide rail; a third driving motor is arranged on the mounting seat, and a rotating disc is fixed to a rotating shaft of the third driving motor; four clamps are arranged on the rotating disc, and a square is formed by the four clamps; and the crossing point of the diagonal lines of the square is located on the axis line of the first driving motor.

Description

technical field [0001] The invention relates to the field of numerically controlled machine tools, in particular to a clamping device for numerically controlled machine tools. Background technique [0002] At present, when a workpiece is processed on a CNC machine tool, a single part is fixed on the workbench. After the CNC machine tool completes the structure of the workpiece, it is necessary to replace the next workpiece and clamp it again, and then process the next workpiece, which cannot be realized. Multiple workpieces are clamped at one time and processed in turn. The work efficiency is low, which increases the production cost of the factory. On the other hand, the existing CNC machine tool has a low degree of freedom of the fixture, and cannot move in a large range on the workbench of the CNC machine tool, and there are processing blind spots. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art a...
