Numerically-controlled machine tool clamp good in fixing effect

Abstract

The invention discloses a numerically-controlled machine tool clamp good in fixing effect. The numerically-controlled machine tool clamp comprises a fixing seat. A first sliding groove is formed in the top of the fixing seat. A first support pillar is fixedly connected to the left side of the top of the fixing seat. An extending-and-contracting rod is fixedly connected to the top of the right sideof the first support pillar. According to the numerically-controlled machine tool clamp good in fixing effect, by means of cooperation among the fixing seat, the first sliding groove, a first slidingblock, a first threaded groove, a first threaded rod, a first rotating disc, a first disc, a first fixing groove, a second sliding groove, a second threaded groove, a second threaded rod, a second disc, a second rotating disc, a first limiting groove, a first fixing plate, a second sliding block, a first reset spring, a second fixing plate, a third sliding block, an electric extending-and-contracting rod, a fourth sliding block and a third fixing plate, the good fixing effect is achieved; the numerically-controlled machine tool clamp can be adjusted according to the size of an object; the economic pressure of a manufacturer is reduced; time required for replacing the clamp is saved; and carrying-out of subsequent cutting work of a numerically-controlled machine tool is guaranteed.

Description

technical field [0001] The invention relates to the technical field of numerically controlled machine tools, in particular to a fixture for numerically controlled machine tools with good fixing effect. Background technique [0002] The CNC machine tool fixture is a device used to clamp the workpiece (and guide the tool) on the CNC machine tool. Its function is to position the workpiece so that the workpiece can obtain the correct position relative to the machine tool and the tool, and clamp the workpiece reliably. Since the working characteristics and structural forms of various machine tools are different, the structure of the fixture used is also corresponding Different requirements were made. According to the different machine tools used, fixtures can be divided into: lathe fixtures, milling machine fixtures, drilling machine fixtures, boring machine fixtures, grinding machine fixtures, gear machine tool fixtures and other machine tool fixtures. [0003] However, the fi...
