Clamping device of numerical control machine tool

Abstract

The invention discloses a clamping device of a numerical control machine tool. The clamping device is wider in moving range, capable of clamping a plurality of workpieces at a time and conducting machining in turn and higher in working efficiency. The clamping device comprises a first base, wherein the first base is in sliding fit with a first moving plate, and a first screw rod is in internal thread fit with the first moving plate and is connected with a first driving motor arranged on the first base; the first moving plate is fixedly provided with a second base which is in sliding fit with a second moving plate, and a second screw rod is in internal thread fit the second moving plate and is connected with a second driving motor arranged on the second base; the second moving plate is provided with a mounting base, and the longitudinal direction of the mounting base is parallel to a second guide rail; the mounting base is provided with a third driving motor; a rotating shaft of the third driving motor is fixedly provided with a turntable on which four fixtures are arranged; the four fixtures form a square; and the intersection point of diagonals of the square is located on the axis 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...
