[0030] Reference Figure 1-3 A precision machine tool positioning device that is easy to guide and position is used for positioning and fixing workpieces in machine tool processing, in order to facilitate the replacement of fixtures to adapt to workpieces of different shapes.

[0031] The precision machine tool positioning device convenient for guiding and positioning comprises a workbench 1, two moving plates 4, two clamping plates 5 and a driving mechanism;

[0032] The workbench 1 is provided with a plurality of parallel chute grooves 101, each of which is slidably connected with a slider 401, and the top of each slider 401 is fixed to the movable plate 4, and the slider 401 can slide along the chute 101, thereby guiding the movable plate 4 to slide on the workbench 1 and approach the workpiece 6. A plurality of slots 402 are provided on the side where the two movable plates 4 are close to each other, and each slot 402 is arranged at equal intervals along the length direction of the movable plate 4. A magnet 501 is fixedly connected to one side of the two clamping plates 5, and each magnet 501 is inserted into a slot 402, so that the movable plate 4 can be moved. So that each clamping plate 5 is fixed to one side of a movable plate 4, and since the movable plate 4 is made of magnetic material, the magnet 501 can be adsorbed in the slot 402 on the movable plate 4, thereby improving the convenience of disassembly and installation of the clamping plate 5 and the movable plate 4, and facilitating the replacement of the clamping plate 5. One side of the clamping plate 5 is arc-shaped or flat. The clamping plate 5 with an arc-shaped side is convenient for clamping cylindrical workpieces, and the clamping plate 5 with a flat side is convenient for clamping square workpieces. Different clamping plates 5 can be replaced by the magnet 501, so that the device can clamp and fix workpieces of different shapes.

[0033] A first fixed box 2 and a second fixed box 7 are fixedly connected to the workbench 1, and a driving mechanism includes a threaded rod 3 and a driving motor 9. The driving motor 9 is arranged inside the first fixed box 2. Two threaded rods 3 are provided, and the two ends of the threaded rod 3 are respectively rotatably connected with the first fixed box 2 and the second fixed box 7. The output shaft of the driving motor 9 and one end of one of the threaded rods 3 are provided with a bevel gear 10, and the two bevel gears 10 are meshed. The two threaded rods 3 are arranged in parallel and have pulleys at the ends. The outer sleeve of the pulley at the same end is provided with a synchronous belt 8. The driving motor 9 can drive one of the threaded rods 3 to rotate, and then through the synchronous belt 8, the two threaded rods 3 rotate synchronously. The threads at the two ends of the threaded rod 3 are in opposite directions. Threaded through holes are opened on the two movable plates 4. The two ends of the threaded rod 3 are respectively threadedly connected with the two movable plates 4 through the two threaded through holes. The driving motor 9 drives the two threaded rods 3 to rotate together, so that the two movable plates 4 move closer to each other on the workbench 1, so that the two clamping plates 5 clamp and fix the workpiece 6.

[0034] The working principle of the precision machine tool positioning device which is convenient for guiding and positioning is as follows: when in use, the workpiece 6 is placed on the workbench 1, and then a suitable clamping plate 5 is selected according to the shape of the workpiece 6. For cylindrical workpieces, a clamping plate 5 with an arc-shaped side is selected, and for square workpieces, a clamping plate 5 with a flat side is selected. When installing the clamping plate 5, the magnet 501 is inserted into the corresponding slot 402. The magnet 501 is inserted into the slot 402 so that the clamping plate 5 is fixed, and suction is generated between the magnet 501 and the moving plate 4 made of magnetic material, so as to further enhance the stability of the clamping plate 5. At the same time, when disassembling, it is also convenient to remove the magnet 501 from the slot 402, so as to facilitate the installation and disassembly of the clamping plate 5.

[0035] Finally, one of the threaded rods 3 is driven to rotate by the driving motor 9, and the threaded rod 3 drives the other threaded rod 3 to rotate synchronously through the synchronous belt 8. Since the threads at both ends of the threaded rod 3 are in opposite directions, the two movable plates 4 move closer to each other through the threads with opposite directions, so that the two clamping plates 5 clamp and fix the workpiece 6.

[0036] 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.
