[0019] The present application will be further described in detail below with reference to all the accompanying drawings.

[0020] This application discloses an intelligent tool magazine for machining centers.

[0021] Reference Figures 1-6 A smart tool magazine for a machining center includes a frame 1, a tool changing mechanism 2, and a machining mechanism 3. A tool magazine housing 4 is fixedly installed on the frame 1. The tool changing mechanism 2 is located between the tool magazine housing 4 and the machining mechanism 3. The machining mechanism 3 is an existing machining equipment for machining workpieces and is prior art, which will not be described in detail in this application.

[0022] A fixing ring 5 is fixedly installed inside the tool magazine housing 4. Two mounting rings 6 are located inside the tool magazine housing 4 on both sides of the fixing ring 5. Both mounting rings 6 are rotatably connected to the tool magazine housing 4. A first motor 11 is fixedly installed on the frame 1. The output shaft of the first motor 11 is connected to a rotating shaft 12. Two rotating gears 13 are coaxially fixedly installed on the rotating shaft 12. The inner side of the two mounting rings 6 is provided with an internal gear ring 61 that mates with the rotating gears 13. When the first motor 11 is started, the rotating shaft 12 rotates, which drives the two mounting rings 6 to rotate.

[0023] The tool magazine housing 4 contains a fixing plate 41 located between a fixing ring 5 and a mounting ring 6. The fixing plate 41 is fixedly connected to the fixing ring 5. On the outer sides of both mounting rings 6, several spacer plates 62 are evenly spaced (circumferentially distributed) around the tool magazine housing 4. Tool holders 63 are located between adjacent spacer plates 62 on the mounting rings 6, each tool holder 63 holding a different tool. The bottom of the tool magazine housing 4 has two tool outlets 42 that mate with the mounting rings 6. The tool magazine housing 4 contains two pushing components 43 for pushing the tool holders 63 out of the tool outlets 42. Each pushing component 43 corresponds to one of the two mounting rings 6. Each pushing component 43 includes a pushing cylinder 431 and a pushing plate 432. A fixing block 44, fixedly connected to the frame 1, is installed inside the tool magazine housing 4. The fixing block 44 is fixedly connected to the fixing ring 5 via a fixing rod 45. The pushing cylinder 431 is fixedly installed inside the tool magazine housing 4 and fixedly connected to the fixing block 44. The pushing plate 432 is fixedly installed on the pushing cylinder 431. At the piston rod end of cylinder 431, a push port 64 with a cross-sectional area smaller than that of the tool holder 63 is provided on the mounting ring 6. The push plate 432 can pass through the push port 64. Mounting plates 65 are fixedly provided on the two mounting rings 6 on the side away from each other. During the rotation of the mounting rings 6, the mounting plates 65 rotate with the mounting rings 6. The fixed plate 41 and the mounting plate 65 are provided with guide grooves 651 along the moving direction of the tool holder 63 on the side near the tool holder 63. Guide blocks 631 located in the guide grooves 651 are provided on both sides of the tool holder 63.

[0024] A first magnetic chuck 632 is installed on the side of the tool holder 6 near the mounting ring 6. A second magnetic chuck 433 that cooperates with the first magnetic chuck 632 is installed on the push plate 432. A third magnetic chuck 66 that cooperates with the first magnetic chuck 632 is installed on the mounting ring 6.

[0025] When the mounting ring 6 is rotated, the designated tool is positioned above the exit port 42. The piston rod of the push cylinder 431 extends, and the push plate 432 moves towards the tool holder 63. The second magnetic suction member 433 on the push plate 432 cooperates with the first magnetic suction member 632 on the tool holder 63, connecting the push plate 432 to the tool holder 63. At the same time, the push plate 432 pushes the tool holder 63 downward, causing the first magnetic suction member 632 to separate from the third magnetic suction member 66. As the tool holder 63 moves towards the exit port 42, the guide block 631 moves along the guide groove 651 to improve the stability of the tool holder 63's movement. When the tool holder 63 extends from the exit port 42, the tool on the extended tool holder 63 is replaced with the tool on the machining mechanism 3 through the tool changing mechanism 2.

[0026] The mounting plate 65 has several unit numbers on its outer side that correspond one-to-one with the cutting tools. Each unit number increases sequentially in a clockwise direction, making it convenient for staff to find the corresponding cutting tool.

[0027] The mounting ring 6 is equipped with a protective plate 67 located at the tool outlet 42. The protective plate 67 can prevent debris from falling into the tool magazine 4 during the machining process and causing damage to the tool and tool holder 63.

[0028] The tool magazine housing 4 has a receiving cavity 46 communicating with two tool outlets 42. A moving slot is formed on the side wall of the fixed plate 41 along the moving direction of the tool holder 63. A moving block 52 is movably disposed within the moving slot. One end of the moving block 52 is fixedly connected to a moving rack 53 located within a fixed ring 5. A connecting plate 54 is fixedly installed within the fixed ring 5. Two connecting wheels 55 are rotatably connected to the connecting plate 54, and the two connecting wheels 55 are connected by a belt 56. Both connecting wheels 55 are coaxially fixedly connected to a connecting gear 57. A connecting gear 57 is provided on the protective plate 67. The rack 671 is connected, with one connecting gear 57 meshing with the moving rack 53 and the other connecting gear 57 meshing with the connecting rack 671. The connecting racks 671 on the two fixed plates 41 are not on the same straight line and do not interfere with each other. A spring plate 58 is installed on the connecting plate 54, and an elastic spring 581 is installed on the spring plate 58. One end of the elastic spring 581 is fixedly connected to the spring plate 58, and the other end is fixedly connected to the end of the moving rack 53. When the elastic spring 581 is in its natural state, the protective plate 67 is located inside the exit port 42. During the movement of the tool holder 63, the tool holder 63 abuts against the moving block 52, causing the moving block 52 to move along the moving slot, driving the moving rack 53 to move. At the same time, the elastic spring 581 deforms, causing one of the connecting gears 5713 to rotate. This rotation, via the connecting wheel 55 and belt 56, drives the other connecting gear 5713 to rotate. Through the connecting rack 671, the protective plate 67 moves from the tool outlet 42 into the receiving cavity 46, extending the tool from the tool outlet 42. After the tool is retracted into the tool magazine housing 4, the tool holder 63 no longer restricts the moving block 52, the elastic spring 581 returns to its original position, driving the moving rack 53 to move, thereby moving the protective plate 67 located in the receiving cavity 46 into the tool outlet 42.

[0029] The tool changing mechanism 2 includes a support frame 21, a tool changing shaft 22, two tool changing arms 23, a lifting assembly 24, and a rotating assembly. The lifting assembly 24 and the rotating assembly are mounted on the support frame 21. The rotating assembly includes a second motor 25 and a drive shaft 251. The second motor 25 is mounted on the support frame 21, and its output shaft is coaxially and fixedly connected to the drive shaft 251. The drive shaft 251 has a polygonal cross-section. The end of the tool changing shaft 22 has a connecting groove that mates with the drive shaft 251. The drive shaft 251 is located in the connecting groove and is movably connected to the tool changing shaft 22. When the second motor 25 is working, the drive shaft 251 rotates and drives the tool changing shaft 22 to rotate.

[0030] The lifting assembly 24 is used to adjust the height position of the tool changer 22. The lifting assembly 24 includes a third motor 241, a rotating disk 242, and a connecting arm 243. The third motor 241 is mounted on the support frame 21, and its output shaft is coaxially and fixedly connected to the rotating disk 242. The rotating disk 242 has an integrated groove, which includes a first arc-shaped groove 244, a second arc-shaped groove 245, and two straight grooves 246. The radius of the first arc-shaped groove 244 is smaller than that of the second arc-shaped groove 245. The radius is such that the first arc-shaped groove 244 and the second arc-shaped groove 245 are connected at both ends by two straight grooves 246. One end of the connecting arm 243 is rotatably connected to the support frame 21, and the other end of the connecting arm 243 is provided with a lifting block 247. Two connecting rings 221 are provided on the outer wall of the tool changing shaft 22. The lifting block 247 is located between the two connecting rings 221, and the upper and lower sides of the lifting block 247 are in contact with the sides of the two connecting rings 221. A synchronization block 248 is provided on the connecting arm 243 located in the integrated groove. Through the design of the first arc-shaped groove 244, the second arc-shaped groove 245 and the two straight grooves 246, as the rotating disk 242 rotates, the synchronization block 248 moves in the integrated groove, causing the connecting arm 243 to swing up and down. The lifting block 247 and the connecting rings 221 drive the tool changing shaft 22 to move up and down reciprocally, so that the tool can move straight up and down relative to the tool holder 63 during the tool changing process, avoiding the tool from shifting during the tool changing process and affecting the connection between the tool and the tool holder 63.

[0031] Two tool changing arms 23 are horizontally positioned and mounted on both sides of the tool changing shaft 22. Support plates 231 are located on both sides of the tool changing shaft 22, and adjusting cylinders 232 are mounted on each support plate 231. A connecting piece 233 is fixedly connected to the piston rod end of the adjusting cylinder 232, and the connecting piece 233 is fixedly connected to the tool changing arm 23. A guide rod 234 is provided at one end of the tool changing arm 23, and a guide groove that mates with the guide rod 234 is provided on the support plate 231. By adjusting the position of the tool changing arm 23 using the adjusting cylinders 232, the tool changing arm 23 is aligned with the positions of the two mounting rings 6, allowing the tool on the machining mechanism 3 to be replaced with the tool on the two different mounting rings 6.

[0032] Working principle: Tool holders 63 are installed between the spacers 62 on the two mounting rings 6. Under the existing spatial layout, the number of tools installed is increased, the tool capacity of the machining center tool magazine is improved, and the machining needs of the machining center using different tools are met. Under the existing spatial layout, the number of tool holders installed is increased. When one tool changing arm 23 is aligned with the tool of the machining mechanism 3 and the other tool changing arm 23 is aligned with the tool on the designated mounting ring 6, the tool changing shaft 22 is moved downward by the lifting component 24, moving the tools of the machining mechanism 3 and the tool magazine housing 4 downward. Then, the tool changing shaft 22 is driven to rotate, and at the same time, the mounting ring 6 in the tool magazine housing 4 is driven to rotate, so that the tools of the machining mechanism 3 can be put back into the corresponding tool holders 63 in the tool magazine housing 4 through the tool changing arm 23. At the same time, new tools are installed on the machining mechanism 3 so that the tools on the machining mechanism 3 can be replaced.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
