Description

Technical Field

[0001] The invention relates to the technical field of processing equipment, and in particular to a multi-axis machine tool fixture. Background Art

[0002] In machine tools, tools are usually set on multiple axes so that they can cut at multiple angles and directions. Currently, there are seven-axis machine tools, which are very convenient to adjust the tools during cutting and have high precision. However, even these most advanced machine tools still have some angles or directions that tools cannot reach, such as drilling from the bottom up. This type of machine tool only focuses on the adjustment of the angle and direction of the tool, but does not consider the adjustment of the angle and direction of the workpiece from the fixture side. If the angle of the workpiece can be adjusted on the workpiece side, then a wider processing range can be achieved, which can reduce the requirements of the machine tool.

[0003] In addition, when processing a circular shape on the workpiece, such as a circular groove, it is very simple to use the workpiece rotation. However, currently the tool rotates around the workpiece, and the tool rotation is superimposed by the horizontal direction and the longitudinal direction. Therefore, the roundness of the circular groove processed by it is not as high as the roundness of the workpiece rotation. Summary of the invention

[0004] In order to solve the problems in the above-mentioned background technology, the present invention provides a multi-axis machine tool fixture for use in a machine tool, and solves the problem in the prior art that the fixture cannot adjust its position at multiple angles.

[0006] The above structure also includes a third connecting rod, which is arranged on one side of the third motor. The center line of the third connecting rod is perpendicular to the rotation center line of the third motor. The length of the third connecting rod is greater than the sum of the length of the first connecting rod, the length of the second connecting rod, the length of the first motor, the diameter of the second motor, and the diameter of the third motor.

The center line of the third connecting rod passes through the center of the second permanent magnetic suction cup. The center line of the third connecting rod is perpendicular to the adsorption plane of the second permanent magnetic suction cup so that the first permanent magnetic suction cup can be adsorbed on the machine tool.

[0008] In the above structure, the first permanent magnetic chuck is electrically connected to the control board so that the control board can control the adsorption surface of the first permanent magnetic chuck to release the workpiece when it is horizontal.

[0009] In the above structure, the second permanent magnetic chuck is electrically connected to the control board so that the control board can control the second permanent magnetic chuck to release the connection between the second permanent magnetic chuck and the machine tool after releasing the workpiece on the adsorption surface of the first permanent magnetic chuck.

[0010] In the above structure, when the center line of the first connecting rod is colinear with the center line of the second connecting rod and the center line of the third connecting rod, the first motor rotates to process the circular shape of the top of the workpiece.

[0011] In the above structure, when the center line of the second connecting rod is perpendicular to the center line of the first connecting rod and / or the center line of the third connecting rod, the first motor rotates to process a circular shape on the side of the workpiece.

[0012] In the above structure, when the center line of the first connecting rod is parallel to the center line of the third connecting rod and the center line of the third connecting rod is perpendicular to the center line of the second connecting rod and / or the first connecting rod, the first motor rotates to process the circular shape of the bottom of the workpiece.

[0013] In the above structure, the first permanent magnetic chuck, the first motor, the first connecting rod, the second motor, the second connecting rod, and the third motor are connected in sequence.

[0014] In the above structure, the first permanent magnetic chuck, the first motor, the first connecting rod, the second motor, the second connecting rod, the third motor, the third connecting rod, and the second permanent magnetic chuck are connected in sequence.

[0015] To sum up, the beneficial effects of the present invention are as follows: by setting the first motor, the second motor, and the third motor, the fixture for fixing the workpiece can adjust the orientation of the workpiece at any time according to the processing status, making it more convenient for the tool to process the workpiece, and the processed workpiece has higher precision and higher roundness precision, which is beneficial to improving the quality of the workpiece and reducing the requirements for equipment during processing.
