[0002] A vertical machining center is a highly automated, multi-functional CNC machine tool. Its working principle involves using a CNC system to control the spindle and feed system to achieve various complex cutting operations. The specific process includes a preparation stage, a programming stage, starting the machining process, executing the machining operation, and completing the machining. In the programming stage, based on the machining plan, a computer generates a CNC program, setting all the necessary machine tool actions and process parameters into information codes that the CNC device can receive, and storing them. These codes are read out during machining and sent to the CNC device. After a series of processing and calculations, they are converted into pulse signals, driving the relevant machine tool components to make the tool and workpiece move according to the preset program. It is equipped with a tool magazine and an automatic tool changer, which can automatically select and change tools, automatically change the machine tool spindle speed, feed rate, and tool-to-workpiece movement trajectory, as well as other auxiliary functions.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Specific Implementation

[0033] This embodiment describes an automatic tool changer for a vertical machining center.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the base 1 and the upper disc 2 are connected together by a horizontal adjustment assembly. The upper disc 2 has a placement opening 3 on its side, which is arranged in an array. The lower side of the upper disc 2 is provided with a connecting post 4, which is engaged with a groove 6. The groove 6 is located on the upper side of the clamping disc 5. The clamping disc 5 is rotatably connected to the lower disc 9. The outer side of the clamping disc 5 is provided with a connecting claw 7, which is arranged in an array and corresponds one-to-one with the placement opening 3. The upper side of the lower disc 9 is provided with a connecting block 8, which is arranged in an array and corresponds one-to-one with the upper disc 2. The upper side of the connecting block 8 is tightly fitted with the lower side of the upper disc 2.

[0035] like Figure 3 , Figure 4 and Figure 5 As shown, a connecting plate 10 is provided on the lower side of the lower disc 9, and a first servo motor 11 is provided on the upper side of the connecting plate 10. The output shaft of the first servo motor 11 is fixedly connected to the full gear 12. The full gear 12 is meshed with the half gear 13. The half gear 13 is located on the outer side of the clamping disc 5. A connecting cylinder 14 is provided on the lower side of the clamping disc 5. The connecting cylinder 14 is slidably connected to the extension column 15. A receiving disc 16 is provided on the lower side of the extension column 15. Limiting holes 17 are provided on the outer side of the extension column 15. The limiting holes 17 are arranged in an array. A connecting bolt 18 is slidably connected inside the limiting holes 17. The connecting bolt 18 is slidably connected to the connecting cylinder 14.

[0036] It should be noted that a lateral moving mechanism is provided on the lower side of the base 1 for movement. The moving mechanism consists of a fixed plate, a limiting rod, a moving block, a lead screw, and a servo motor. The moving mechanism allows the tool to move as a whole with the movement of the upper disc 2, and then connect with the tool connecting assembly in the connecting frame. For the specific operation method, please refer to the comparison patent. This patent is an improvement on the comparison patent and plays a protective role for the tool. The specific connection method is not the focus of this patent.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, before placing different tools in the middle of the placement opening 3, the first servo motor 11 on the upper side of the connecting plate 10 needs to be started. The first servo motor 11 will drive the full gear 12 to rotate, and the rotating full gear 12 will drive the half gear 13 to rotate, thereby causing the clamping plate 5 to rotate. Since the upper disc 2 and the lower disc 9 are connected together by the connecting block 8, there will be a space in the middle of the upper disc 2 and the lower disc 9 for the clamping plate 5 to rotate. In addition, a connecting post 4 is provided on the lower side of the upper disc 2. The connecting post 4 is engaged with the groove 6 on the upper side of the clamping plate 5 to prevent the clamping plate 5 from tilting when rotating, so that the connecting claw 7 can rotate in the upper disc 2 and the lower disc 9 with the center of the upper disc 2 and the lower disc 9 as the center. When the connecting claw 7 rotates through the half gear 13, the tool will be clamped in the middle of the connecting claw 7 and the placement opening 3 to prevent it from falling off.

[0038] In addition, the rotation direction of the upper disc 2 is opposite to that of the clamping disc 5, thereby preventing the tool from disconnecting from the connecting claw 7 and thus preventing the tool from falling accidentally. When the tool needs to be replaced, the connecting claw 7 is rotated in the opposite direction. At this time, the tool is no longer restricted by the connecting claw 7 and can be replaced. After the replacement is completed, the connecting claw 7 is still needed to restrict the tool.

[0039] like Figure 3 , Figure 4 and Figure 5 As shown, the lower side of the clamping plate 5 is provided with a connecting cylinder 14, an extension column 15 and a receiving plate 16. The upper side of the receiving plate 16 is provided with cushioning cotton. When the tool is accidentally dropped, the cushioning cotton can cushion the tool and prevent damage. The lengths of the connecting cylinder 14 and the extension column 15 are adjustable, which makes it convenient to place tools of different lengths. First, remove the connecting bolt 18. After the height is adjusted, connect the connecting bolt 18 with the limiting hole 17 inside the connecting cylinder 14 and the extension column 15 to achieve the purpose of adjusting the height.
