Description

A turning fixture for CNC machine tools

Technical Field

The utility model relates to the technical field of jigs, in particular to a turning jig for CNC machine tools.

Background Art

A fixture is a large category of tools for carpentry, ironwork, fitter, machinery, electronic control and some other handicrafts. It is mainly used as a tool to assist in controlling position or motion (or both). Many fixtures are produced due to business needs, because there are many types of fixtures that are customized, some of which are designed to improve productivity, repeat specific actions, or make work more precise, while fixtures focus on work and guide tools.

CNC machine tool is the abbreviation of numerical control machine tool. After calculation and processing, the numerical control device sends various control signals to control the movement of the machine tool, and automatically processes the parts according to the shape and size required by the drawing. However, most of the existing CNC machine tool fixtures are fixed, which is not convenient for rotating and adjusting the angle of the fixture. For some workpieces that need to be processed by four axes, after the CNC machine tool completes the processing of two axes, the direction of the workpiece is changed to process the other two axes, which causes inconvenience.

A fixture is a large category of tools for carpentry, ironwork, fitter, machinery, electronic control and some other handicrafts. It is mainly used as a tool to assist in controlling position or motion (or both). Many fixtures are produced due to business needs, because there are many types of fixtures that are customized, some of which are designed to improve productivity, repeat specific actions, or make work more precise, while fixtures focus on work and guide tools.

CNC machine tool is the abbreviation of numerical control machine tool. After calculation and processing, the numerical control device sends various control signals to control the movement of the machine tool, and automatically processes the parts according to the shape and size required by the drawing. However, most of the existing CNC machine tool fixtures are fixed, which is not convenient for rotating and adjusting the angle of the fixture. For some workpieces that need to be processed by four axes, after the CNC machine tool completes the processing of two axes, the direction of the workpiece is changed to process the other two axes, which causes inconvenience.

In order to solve the above problems, the present embodiment discloses a flip jig for a CNC machine tool, the structure of which is shown in FIG1 .
