[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] according to Figure 1-4 As shown: The utility model provides a chuck for CNC polishing of metal parts: it includes a workbench 1, a support frame 2 is fixedly connected to the workbench 1, and a polishing assembly 3 is arranged in the support frame 2; fixed boxes 5 are fixedly arranged on both sides of the support frame 2, and a first chuck 6 and a second chuck 9 are respectively arranged on one side of the two fixed boxes 5; the first chuck 6 is located at a position corresponding to the polishing assembly 3, and the second chuck 9 is located at a position away from the polishing assembly 3; the first chuck 6 and the second chuck 9 are slidably arranged on the workbench 1, and the two fixed boxes 5 are respectively provided with a first motor 4 and a second motor 10 that can control the sliding of the first chuck 6 and the second chuck 9; a control unit 8 connected to the first motor 4 and the second motor 10 is arranged on the support frame 2, and a pressure sensor 15 connected to the control unit 8 is arranged in the workbench 1, a cylindrical workpiece 7 is placed on the pressure sensor 15, and the pressure sensor 15 is located away from the polishing assembly 3.

[0021] By providing the sliding first chuck 6 and the second chuck 9, not only can the metal part be clamped and fixed, but the workpiece 7 can also be loaded and unloaded by utilizing the sliding of the two chucks, thus avoiding safety risks caused by workers directly operating and contacting the chucks.

[0022] like Figure 3 As shown, a sliding structure fixedly connected to the first chuck 6 and the second chuck 9 is slidably arranged in the fixed box 5. The sliding structure includes a moving plate 11 and a sliding rod 13. The moving plate 11 is slidably arranged in the fixed box 5, and the sliding rod 13 is fixedly connected to the moving plate 11; the sliding rod 13 slides through the fixed box 5, and the sliding rod 13 is respectively fixedly connected to the first chuck 6 and the second chuck 9. The output shafts of the first motor 4 and the second motor 10 are both fixedly connected with a screw rod 12 rotatably arranged in the fixed box 5; the moving plate 11 is threadedly connected to the screw rod 12; the inner wall of the fixed box 5 and the moving plate 11 are corresponding rectangular parallelepiped structures, and the moving plate 11 and the inner wall of the fixed box 5 fit each other, which can limit the rotation of the moving plate 11, thereby converting the rotation of the screw rod 12 into the movement of the moving plate 11, and driving the chuck to slide through the sliding rod 13.

[0023] like Figure 4 As shown, the control unit 8 is connected to the polishing assembly 3; a working state light 14 is provided on the support frame 2, and the control unit 8 is connected to the working state light 14 circuit, which is convenient for indicating the working state and reminding the staff.

[0024] Principle of the utility model

[0025] like Figure 1-2As shown, during operation, the workpiece 7 is placed on the pressure sensor 15; since the pressure sensor 15 is located away from the polishing assembly 3, there is no risk of contact between the workpiece 7 and the polishing assembly 3 when the workpiece 7 is placed; after the pressure sensor 15 senses the pressure, it transmits a signal to the control unit 8, and the control unit 8 controls the second motor 10 to start, as shown in FIG. Figure 3 As shown, the sliding of the movable plate 11 drives the sliding of the second chuck 9, and the second chuck 9 pushes the workpiece 7 toward the direction close to the first chuck 6 until the workpiece 7 is completely fixed in the two chucks. At this time, the workpiece 7 is located directly below the polishing assembly 3, and the control unit 8 controls the polishing assembly 3 to work and polish the workpiece 7. When the workpiece 7 is placed on the pressure sensor 15, the controller controls the working status light 14 to light up red, indicating that the polishing work is in progress.

[0026] After the polishing work is completed, the control unit 8 first controls the second motor 10 to reverse, and under the drive of the movable plate 11, the second chuck 9 returns to its original position; the first motor 4 is started with a delay, so that the first chuck 6 pushes the workpiece 7 towards the direction close to the second chuck 9, and pushes the workpiece 7 to the position of the pressure sensor 15 again. After the pressure sensor 15 senses the pressure for the second time, the controller controls the working status light 14 to light up green, indicating that the polishing work is completed; and at this time, when the staff takes out the polished workpiece 7, it is also from a position away from the polishing assembly 3, and there is no risk of contact with the polishing assembly 3.

[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
