[0035] Reference Figure 1-6 A precision machine tool positioning structure that is easy to adjust is used for positioning and fixing workpieces during machine tool processing. In order to process the inclined surface of the workpiece, it is easy to adjust the angle of the workpiece.

[0036] The easily adjustable precision machine tool positioning structure comprises a base 1, a support column 11, a workbench 5 and two clamping components;

[0037] The support column 11 is fixedly connected to the base 1, and a fixed ball 12 is fixedly connected to the upper end. A movable sleeve 13 is fixedly connected to the bottom of the workbench 5. A spherical movable groove is provided at the bottom of the movable sleeve 13. The fixed ball 12 is embedded in the movable groove. The movable sleeve 13 can rotate around the fixed ball 12, so that the workbench 5 can be deflected at an angle, so that the angle of the workbench 5 can be adjusted. After the workpiece 9 is fixed on the workbench 5 by the clamping assembly, the angle of the workbench 5 can be changed together by adjusting the angle of the workbench 5, so as to facilitate inclined surface processing.

[0038] In order to improve the stability of the angle adjustment of the workbench 5, a movable cylinder 4 is fixedly connected to the bottom of the workbench 5. The outer wall of the movable cylinder 4 is spherical, and a circular opening is provided on the base 1. The outer wall of the movable cylinder 4 fits with the circular opening and can move in the circular opening. When the angle of the workbench 5 is adjusted, the movable cylinder 4 will move accordingly, thereby moving in the circular opening to support the workbench 5, thereby ensuring the stability of the angle adjustment of the workbench 5, and also facilitating the subsequent processing of the workpiece 9 on the workbench 5.

[0039] In order to fix the angle of the workbench 5, a plurality of fixing components are provided on the base 1 around the movable cylinder 4, each fixing component includes a first push rod 2 and a fixing block 3. The first push rod 2 is an electric push rod, one end of the first push rod 2 is fixedly connected to the base 1, and the other end is fixed to the fixing block 3. One side of the fixing block 3 is inclined to adapt to the outer wall of the movable cylinder 4, and a rubber plate 301 is provided on the inclined side wall. Each first push rod 2 can push a fixing block 3 to move. Since the fixing components are arranged around the movable cylinder 4, the plurality of first push rods 2 will push the fixing block 3 from all directions to clamp the outer wall of the movable cylinder 4, and the rubber plate 301 will fit the outer wall of the movable cylinder 4, so that the movable cylinder 4 after the angle is adjusted is fixed, which is convenient for processing the workpiece 9. In addition, the inner wall of the movable cylinder 4 is fixedly connected with a reinforcing rod 10, and the upper end of the reinforcing rod 10 is fixedly connected to the bottom of the workbench 5. The reinforcing rod 10 can increase the stability of the movable cylinder 4, thereby facilitating the movable cylinder 4 to support the workbench 5.

[0040] Each clamping assembly includes a movable plate 7, two clamping plates 6 and a second push rod 8. The second push rod 8 is an electric push rod. One end of the second push rod 8 is fixedly connected to the workbench 5, and the other end is fixedly connected to the movable plate 7. The movable plate 7 is slidably connected to the workbench 5. Two slots 701 are provided on the top surface of the movable plate 7. The bottoms of the two clamping plates 6 are fixedly connected to fixed rods 602. The outside of each fixed rod 602 is provided with a gear ring, and each fixed rod 602 is adapted to a slot 701. The second push rod 8 can push the movable plate 7 to move on the workbench 5, so that the clamping plates 6 on the two clamping assemblies are close to each other, so as to clamp and fix the workpiece 9. When the circular workpiece 9 needs to be clamped and fixed, the angle of the clamping plate 6 can be changed first, and then the clamping plate 6 with the changed angle can be inserted downward on the movable plate 7. Since a gear ring is provided on the outside of the fixing rod 602, the fixing rod 602 and the card slot 701 are adapted, and the fixing rod 602 can be inserted into the card slot 701 after the angle of the clamping plate 6 is changed, so that the clamping plate 6 after the angle is changed is fixed on the movable plate 7. The four clamping plates 6 are convenient for processing the circular workpiece 9, and since a rubber pad 601 is provided on one side of the clamping plate 6, the rubber pad 601 can prevent the clamping plate 6 from causing damage to the workpiece 9, thereby improving the precision of the processing of the workpiece 9.

[0041] Working principle of this easy-to-adjust precision machine tool positioning structure:

[0042] First, the workpiece 9 is fixed on the workbench 5 by the clamping assembly, and the second push rod 8 pushes the moving plate 7 to move on the workbench 5, so that the clamping plates 6 on the two clamping assemblies are close to each other, thereby clamping and fixing the workpiece 9 on the workbench 5;

[0043] When the workpiece 9 needs to be processed on an inclined surface, since the movable sleeve 13 can be movable outside the fixed ball 12, the workbench 5 can be deflected at an angle, so the workbench 5 can be adjusted in angle. The angle of the workpiece 9 can be changed together by adjusting the angle of the workbench 5, which is convenient for processing the inclined surface. After the angle adjustment is completed, the fixed block 3 is pushed from all directions by multiple first push rods 2 to clamp the outer wall of the movable cylinder 4, and the rubber plate 301 will fit the outer wall of the movable cylinder 4 to fix the movable cylinder 4, so that the workbench 5 after the angle adjustment is fixed, which is convenient for processing the inclined surface of the workpiece 9 on the workbench 5.

[0044] When the circular workpiece 9 needs to be processed, the angles of each clamping plate 6 are adjusted before the workpiece 9 is fixed. Since a gear ring is provided on the outside of the fixing rod 602, the fixing rod 602 and the slot 701 are adapted. The fixing rod 602 can be inserted into the slot 701 after the clamping plate 6 changes its angle, so that the clamping plate 6 after the angle is changed is fixed on the movable plate 7. The four clamping plates 6 clamp and fix the circular workpiece 9 under the action of the second push rod 8, thereby facilitating the processing of the circular workpiece 9.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
