[0023] like Figure 1-4 As shown, a CNC machine tool for batch processing includes a three-axis machine base, a fixture 1, a frame 2, and a tool holder 3. The tool holder 3 is located above the fixture 1. The top of the fixture 1 is provided with a plate 14 for placing blanks 17. The top of the plate 14 is provided with several crisscrossing air grooves 15. Vacuum holes 16 are provided at the intersection of two air grooves 15. The vacuum holes 16 are connected to an external vacuum pump. After the blanks 17 are placed on the plate 14, the vacuum pump will adsorb the blanks 17 through the vacuum holes 16 to prevent the blanks from loosening during processing and improve processing quality. The air grooves 15 can increase the adsorption of the blanks. The fixture 1 is fixed on the support platform of the three-axis machine tool. There are two box frames 2, which are symmetrically arranged about the fixture 1. One box frame 2 is used to stack blanks, and the other box frame 2 is used to stack products (finished blanks). The top of the support platform is provided with positioning plates 7 that correspond one-to-one with the two box frames 2. The top of the positioning plates 7 is provided with two positioning posts 8, and the bottom of the box frames 2 is provided with positioning holes that correspond one-to-one with the two positioning posts 8. This allows both box frames 2 to be detachably connected to the support platform, which is convenient for batch loading and unloading of materials. It can process blanks in batches, avoid frequent machine stops for loading and unloading of materials, improve processing efficiency, and reduce the labor intensity of operators.

[0024] The top of the tool holder 3 is connected to the tool magazine of the three-axis machine tool. A mounting plate 9 is fixed to the bottom of the tool holder 3, and a clamping cylinder 5 is fixed to the bottom of the mounting plate 9. Air pipes 4 are fixed to both sides of the clamping cylinder 5, which can be used to purge the air groove 15 to avoid reducing the adsorption effect on the blank and to purge the blank, improving the finished product quality. Clamping plates 6 are fixed to the output ends of both ends of the clamping cylinder 5. A first three-way valve 10 and a second three-way valve 11 are fixed to the side of the tool holder 3. The air inlet of the No. 1 three-way valve 10 is connected to the external No. 1 air pump. Both exhaust ports of the No. 1 three-way valve 10 are connected to the clamping cylinder 5 through the No. 1 air pipe 12, which provides air supply to the clamping cylinder 5 and allows the output end of the clamping cylinder 5 to extend or retract. The air inlet of the No. 2 three-way valve 11 is connected to the external No. 2 air pump. Both exhaust ports of the No. 2 three-way valve 11 are connected to two blowing pipes 4 through the No. 2 air pipe 13, which provides air supply to the blowing pipes 4 and allows the blowing pipes 4 to perform a purging function.

[0025] The three-axis machine tool includes a support frame, a drive cylinder, a first linear motor, and a second linear motor. The drive cylinder and the first linear motor are fixed to the support frame. The output end of the drive cylinder is fixedly connected to the tool magazine. The second linear motor is fixed to the mover of the first linear motor. The support platform is fixed to the mover of the second linear motor. The drive cylinder drives the tool magazine to move up and down, the first linear motor drives the second linear motor to move forward and backward, and the second linear motor drives the support platform to move left and right, thus enabling the support platform to move forward, backward, left, and right. The drive cylinder is connected to the CNC machine's air supply system. The vacuum pump, the first air pump, the second air pump, the drive cylinder, the first linear motor, and the second linear motor are all electrically connected to the CNC machine's controller.

[0026] Working principle:

[0027] like Figure 1 and 2 As shown, when the material handling device is in use, open the working door of the CNC machine, then take out the box rack 2 used for stacking blanks 17, place the batch of blanks 17 into the box rack 2, then align the box rack 2 and place it into the corresponding positioning plate 7, then close the working door, start the CNC machine, and call the NC program that has been edited in advance in the controller.

[0028] First, by coordinating the first and second linear motors, the fixture 1 is moved to directly below the tool holder 3. Then, the second air pump blows the plate 14 on top of the fixture 1 through the air pipe 4. After the blowing time reaches the set time, the second air pump is turned off.

[0029] The second step involves using the cooperation of linear motor 1 and linear motor 2 to move the box frame 2 containing the stacked blanks 17 directly below the tool holder 3. Then, air pump 1 is activated, and the clamping plates 6 at both ends of clamping cylinder 5 are opened. After that, the drive cylinder drives the tool holder 3 to descend to the set height, and air pump 1 is turned off. The two clamping plates 6 will then clamp the blanks 17. After that, the drive cylinder drives the tool holder 3 to rise back to its original position. Then, using the cooperation of linear motor 1 and linear motor 2, the fixture 1 is moved directly below the tool holder 3. The drive cylinder drives the tool holder 3 to descend, allowing the blanks 17 to be placed on the plate 14. Clamping cylinder 5 releases the blanks 17, and then the drive cylinder drives the tool holder 3 to rise back to its original position.

[0030] The third step is to start the vacuum pump and suck up the blank 17 through the vacuum hole 16. Then, through the cooperation of the first linear motor and the second linear motor, the blank 17 is moved to the corresponding processing position. Then, the processing module in the CNC machine will perform processing operation on the blank 17. After the blank 17 is processed, the product is moved to the bottom of the tool holder 3 through the cooperation of the first linear motor and the second linear motor. Then, the second air pump blows the surface of the product through the air pipe 4. After the blowing time reaches the set time, the second air pump and the vacuum pump are turned off.

[0031] Fourth step: The first air pump is started, the clamping plates 6 at both ends of the clamping cylinder 5 are opened, and then the drive cylinder drives the knife handle 3 to descend to the set height. After that, the first air pump is turned off, and the two clamping plates 6 will clamp the product. Then, the drive cylinder drives the knife handle 3 to rise back to the original position. Through the cooperation of the first linear motor and the second linear motor, the box rack 2 used for stacking products moves to directly below the knife handle 3. Then, the drive cylinder drives the knife handle 3 to descend to the set height, and the clamping cylinder 5 releases the blank 17, allowing the product to be stacked in the box rack 2. After that, the drive cylinder drives the knife handle 3 to rise back to the original position.

[0032] Continue running the NC program, repeating steps one through four until all blanks 17 are processed. Then open the CNC machine's working door and take out the stacking rack 2 for stacking products. This allows for batch processing of blanks, avoiding frequent machine stops for material handling and improving processing efficiency while reducing the workload of operators.
