Description

Technical Field

[0001] This utility model relates to the field of disc-type tool magazine technology, and in particular to a disc-type tool magazine for vertical machining centers. Background Technology

[0002] A disc-type tool magazine typically consists of a tool disc, a drive motor, a robotic arm, and a tool position detection device. The tool changing process generally includes several steps, such as tool selection, rotating the tool disc to the target position, the robotic arm grabbing the tool, and exchanging the old and new tools. First, the CNC system issues a command, the tool magazine starts selecting a tool, then positions itself in the correct position, then the robotic arm extends and clamps the tool, the old tool on the spindle is released, the robotic arm rotates to exchange the old and new tools, and finally resets.

[0003] However, after the old tool is finished, its surface is often covered with foreign objects such as metal shavings. If it is not cleaned and put directly back into the tool magazine, the entire tool magazine may be contaminated with foreign objects, which is not conducive to the accuracy control of precision machining center products, nor to the management of tool life. In addition, before a new tool is placed in the tool magazine and reloaded, its surface may have accumulated dust and other foreign objects. If it is not cleaned before loading the tool, it may affect the product quality and accuracy. Based on this, a disc-type tool magazine for vertical machining centers is proposed. Utility Model Content

[0004] To address the technical problem of cleaning tools in disc-type tool magazines, this utility model provides a disc-type tool magazine for vertical machining centers.

[0005] This utility model is achieved using the following technical solution: a disc-type tool magazine for a vertical machining center, comprising a rotating plate and a tool magazine. Gripper units are fixedly connected to both ends of the rotating plate. Multiple sliding rods are slidably connected to the rotating plate. A connecting plate is fixedly connected to the lower ends of the multiple sliding rods. Limiting cylinders are fixedly connected to both ends of the connecting plate. Sleeves are rotatably connected to the inner sides of the two limiting cylinders. Multiple brushes are fixedly connected to the inner sides of the two sleeves. A limiting drive mechanism is provided on one side of each of the two limiting cylinders. A tool changing mechanism is provided on one side of the tool magazine. A tool magazine base is fixedly connected to the lower side of the tool magazine.

[0006] As a further improvement to the above solution, the limiting drive mechanism includes multiple spiral grooves respectively opened on the outer sides of the two sleeves, limiting grooves respectively opened on the outer sides of the two limiting cylinders, and a locking rod pushing mechanism respectively provided on the inner side of the two limiting grooves.

[0007] As a further improvement to the above solution, the lever pushing mechanism includes two insert plates that are fixedly connected to the lower side of the rotating plate. A pointer is fixedly connected to the lower end of each insert plate near the sleeve. The insert plates on each side are slidably connected to the inner side of the limiting groove on the same side, and the pointer is slidably connected to the inner side of the spiral groove.

[0008] As a further improvement to the above solution, the tool changing mechanism includes a mounting plate rotatably connected to the upper ends of the two slide bars. One side of the mounting plate is fixedly connected to one side of the tool magazine. The upper side of the mounting plate is provided with a tool changing and swapping mechanism that rotates the rotating plate, and the lower side of the mounting plate is provided with a tool pulling mechanism that pulls out the old and new tools.

[0009] As a further improvement to the above solution, the tool changing and adjusting mechanism includes a servo motor fixedly connected to the upper side of the mounting plate. The output end of the servo motor is fixedly connected to a second bevel gear, which meshes with a first bevel gear. The first bevel gear is rotatably connected to the upper side of the mounting plate, and the lower side of the first bevel gear passes downward through the mounting plate and is fixedly connected to the upper ends of the two slide rods.

[0010] As a further improvement to the above solution, the knife-pulling mechanism includes a hydraulic cylinder that is fixedly connected to both of the slide bars, and the output end of the hydraulic cylinder is fixedly connected to the upper side of the rotating plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a hydraulic cylinder to push down, which drives the rotating plate and the insert plate to press down. The pointer in the limit groove interacts with the spiral slide groove to push the sleeve to rotate. The brush set inside the sleeve can rotate and clean the side surface of the tool, avoiding the accumulation of foreign matter on the tool surface over a long period of time, which would reduce the service life of the tool.

[0013] 2. This utility model can not only clean the surface of old tools that have just been processed, but also clean the surface of new tools that have just come out of the tool magazine. The cleaned new tools help improve the precision of the tools, and indirectly improve the quality and pass rate of the products. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Example:

[0022] Please combine Figure 1 - Figure 4 This embodiment of a vertical machining center disc-type tool magazine includes a rotating plate 5 and a tool magazine 2. The two ends of the rotating plate 5 are respectively fixedly connected to gripper units 8, which can firmly grip the sides of the tools on both sides. In this embodiment, two slide rods 9 are slidably connected on the rotating plate 5. The lower ends of the two slide rods 9 are fixedly connected to a connecting plate 6. The two ends of the connecting plate 6 are respectively fixedly connected to limit cylinders 7. Each limit cylinder 7 is located directly below each gripper unit 8. The inner sides of the two limit cylinders 7 are respectively rotatably connected to sleeves 15. The inner sides of the two sleeves 15 are respectively fixedly connected to three brushes 17. One side of each of the two limit cylinders (7) is provided with a limit drive mechanism. One side of the tool magazine 2 is provided with a tool changing mechanism. The lower side of the tool magazine 2 is fixedly connected to a tool magazine base 1.

[0023] Please combine Figure 3 As shown, in this embodiment, the limiting drive mechanism includes two spiral grooves 16 respectively opened on the outer sides of the two sleeves 15. The starting and ending angles of the spiral grooves 16 are adapted to the switching angles of the new and old tools. Limiting grooves 18 are respectively opened on the outer sides of the two limiting cylinders 7, and a locking rod pushing mechanism is respectively provided on the inner side of the two limiting grooves 18.

[0024] Please combine Figure 3As shown, the lever pushing mechanism includes two insert plates 10 fixedly connected to the lower side of the rotating plate 5. One end of the insert plate 10 is inserted into the limiting groove 18, and the pointer 14 on the side is located in the spiral groove 16. The lower end of the two insert plates 10 is fixedly connected to the pointer 14 on the side near the sleeve 15. The insert plate 10 on each side is slidably connected to the inner side of the limiting groove 18 on the same side, and the pointer 14 is slidably connected to the inner side of the spiral groove 16. When the insert plate 10 drives the pointer 14 to move up and down, it can drive the sleeve 15 to rotate forward or backward inside the limiting cylinder 7.

[0025] Please combine Figure 1 As shown, the tool changing mechanism includes a mounting plate 4 that is rotatably connected to the upper ends of the two slide bars 9. One side of the mounting plate 4 is fixedly connected to one side of the tool magazine 2. The upper side of the mounting plate 4 is provided with a tool changing and swapping mechanism that rotates the rotating plate 5, and the lower side of the mounting plate 4 is provided with a tool pulling mechanism that pulls out the old and new tools.

[0026] Please combine Figure 2 As shown, the tool changing and adjusting mechanism includes a servo motor 3 fixedly connected to the upper side of the mounting plate 4. The output end of the servo motor 3 is fixedly connected to a second bevel gear 13, which meshes with a first bevel gear 12. The first bevel gear 12 is rotatably connected to the upper side of the mounting plate 4. The lower side of the first bevel gear 12 passes downward through the mounting plate 4 and is fixedly connected to the upper ends of the two slide rods 9. It should be noted that when the second bevel gear 13 pushes the first bevel gear 12 to rotate, the lower end of the first bevel gear 12 passes through the mounting plate 4 and can directly push the hydraulic cylinder 11 and the two slide rods 9 to rotate, thereby realizing the turning of the rotating plate 5 and the connecting plate 6.

[0027] The tool-pulling mechanism includes a hydraulic cylinder 11 fixedly connected to two slide rods 9. The output end of the hydraulic cylinder 11 is fixedly connected to the upper side of the rotating plate 5. When the hydraulic cylinder 11 is started, it can push the rotating plate 5 to slide up and down along the slide rods 9. On the one hand, it can pull out and install the new and old tools fixed by the gripper unit 8 on both sides. On the other hand, it can insert the pulled-out tool into the sleeve 15 and the insert plate 10 can move up and down in the limiting groove 18. The up and down movement of the insert plate 10 and the pointer 14 can drive the brush 17 to rotate, so as to achieve the cleaning work.

[0028] The implementation principle of a disc-type tool magazine for a vertical machining center in this embodiment is as follows: When the working wheel of the tool magazine 2 rotates, the selected tool extends from the bottom. The servo motor 3 is started to drive the second bevel gear 13, which in turn drives the first bevel gear 12 to rotate through meshing. Since the lower side of the first bevel gear 12 passes through the mounting plate 4 and is fixedly connected to the hydraulic cylinder 11 and the slide rod 9, when the first bevel gear 12 rotates, it can drive the hydraulic cylinder 11, the rotating plate 5 and the connecting plate 6 to rotate together. After rotating 180 degrees, the gripper unit 8 grabs the new tool extending from the bottom of the tool magazine 2 at one end and the old tool that needs to be replaced from the machining center at the other end. After both ends are grabbed, the hydraulic cylinder 11 is started to push the rotating plate 5 downward. At this time, the rotating plate 5 moves downward relative to the slide rod 9, so that the new and old tools grabbed at both ends of the rotating plate 5 are simultaneously inserted into the sleeve 15.

[0029] Meanwhile, since the insert plates 10 are fixedly connected to both sides of the lower side of the rotating plate 5, the insert plates 10 slide down along the inside of the limiting groove 18, and the pointer 14 fixedly connected to one side of the insert plate 10 is inserted into the spiral groove 16 on the outside of the sleeve 15. At this time, the pointer 14 can push the sleeve 15 to rotate. The rotation of the sleeve 15 indirectly drives the brush 17 installed inside the sleeve 15 to rotate, thereby realizing the function of the brush 17 cleaning the new and old tools inserted into the sleeve 15 on both sides. After cleaning, the servo motor 3 starts and pushes the rotating plate 5 to rotate, realizing the turning of the new and old tools on both sides. Then the hydraulic cylinder 11 is started again to push the rotating plate 5 upward in the opposite direction. At this time, the brush 17 reverses and realizes cleaning again. At the same time, the gripper units 8 on both sides are pushed upward, and the new tool is reinserted into the machining center, while the old tool is put back into the tool magazine 2.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
