Description

Technical Field

[0001] This utility model relates to the technical field of gantry drilling and milling machining centers, and more specifically, to a tool magazine structure for a gantry drilling and milling machining center. Background Technology

[0002] Gantry milling and drilling machining centers, as high-precision and high-efficiency metal cutting equipment, are widely used in aerospace, rail transportation, heavy machinery and other fields. Their tool magazine, as a core functional component, directly determines the tool changing efficiency, machining accuracy and long-term operational stability of the equipment.

[0003] Currently, the tool magazines in gantry milling and drilling machining centers on the market lack adequate dust protection. Most tool magazines, due to their simplified structure, lack effective sealing and protection mechanisms, or only use simple grilles and baffles for shielding. During machining, dust, metal shavings, cutting fluid droplets, and other impurities from the external environment can easily enter the tool magazine. These impurities not only adhere to the cutting edges of the milling cutters and the surfaces of the clamping components, leading to decreased tool accuracy and shortened tool life, but may also seep into the drive mechanism (such as the motor and gear set), causing component wear, jamming, and other malfunctions. This seriously affects the long-term stable operation of the tool magazine, increasing equipment maintenance costs and downtime. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art, and then to propose a tool magazine structure for a gantry drilling and milling machining center.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A tool magazine structure for a gantry milling and drilling machining center includes an outer shell with an opening and a door assembly installed at the opening. A drive motor is installed inside the outer shell and connected to a mounting bracket. Multiple push cylinders are arranged circumferentially on the mounting bracket. Each push cylinder is connected to a set of clamping components for fixing the milling cutter. The clamping components cooperate with the opening. When changing tools, the door assembly automatically opens, and the corresponding push cylinder pushes the clamping component connected to it to the outside of the opening.

[0006] Furthermore, the above solution includes two guide rails vertically and symmetrically arranged on both sides of the opening, with a stop door slidingly fitted on both guide rails, and the stop door is connected to a telescopic cylinder disposed on the outer shell.

[0007] Furthermore, in the above solution, the telescopic cylinder extends to close the opening with the stop gate, and retracts to move the stop gate away from the opening, thus opening the opening.

[0008] Furthermore, the above solution includes a mounting base connected to a push cylinder, a limiting seat on the mounting base, clamping plates symmetrically arranged on both sides of the limiting seat, and each clamping plate is connected to the mounting base through a rotating shaft, and a spring is connected between the tail ends of the two clamping plates to make the clamping ends of the two clamping plates elastic.

[0009] Furthermore, the above solution includes a push cylinder mounted on a mounting bracket via an adjustment component, allowing for fine-tuning of the push cylinder's forward distance.

[0010] Furthermore, the above solution includes a slide rail horizontally mounted on a mounting bracket, a slider for mounting a push cylinder slidably fitted on the slide rail, and the slider is connected to the slide rail by a positioning bolt.

[0011] Furthermore, the above solution includes an open top panel with a cover for mounting the drive motor, and the cover is connected to the outer casing by fastening bolts.

[0012] Furthermore, the above-mentioned solution includes an open top cover for mounting a drive motor, and two vertically mounted lifting cylinders connected to the cover on the outer casing.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention features a door assembly at the opening of the outer casing, which remains closed when the tool magazine is not in operation. This creates a completely sealed protective space, effectively preventing external dust, metal shavings, cutting fluid droplets, and other impurities from entering the casing. This reduces equipment maintenance frequency and costs, ensures long-term stable operation of the tool magazine, and enhances the continuous operation capability of the machining center. When the machining center triggers a tool change command, the system sequentially controls the door assembly to automatically open, the drive motor to precisely rotate the mounting bracket to the target drill / end mill cutter position, and the push cylinder to push the clamping assembly and drill / end mill cutter outside the opening. The entire process requires no manual intervention, significantly shortening the tool change cycle and improving tool change efficiency. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: A tool magazine structure for a gantry milling and drilling machining center, see attached figure. Figure 1 and attached Figure 2 As shown, the tool magazine includes an outer casing 1 with an opening 11 for drill and milling cutters to enter and exit. A door assembly 2 is installed at the opening 11. The door assembly 2 remains closed when the tool magazine is not in operation, effectively preventing external dust, debris, and other impurities from entering the outer casing 1 and avoiding contamination or damage to internal components and drill and milling cutters, thus ensuring long-term stable operation of the tool magazine. A drive motor 3 is installed inside the outer casing 1, and the drive motor 3 is connected to a mounting bracket 4, which can drive the mounting bracket 4 to achieve precise circumferential rotation. Multiple push cylinders 5 are arranged circumferentially on the mounting bracket 4. The number of push cylinders 5 can be adapted according to the actual storage requirements of drill and milling cutters. Each push cylinder 5 is connected to a set of clamping components 6 for fixing drill and milling cutters. The clamping components 6 cooperate with the opening 11. When changing tools, the door assembly 2 automatically opens, and the corresponding push cylinder 5 pushes the clamping components 6 connected to it to the outside of the opening 11.

[0016] In the specific implementation process, when the machining center triggers the tool change command, the system first controls the door assembly 2 to open automatically, so that the opening 11 of the outer shell 1 is unobstructed; then the drive motor 3 starts, driving the mounting bracket 4 to rotate to the position where the clamping assembly 6 corresponding to the target drill and milling cutter is aligned with the opening 11; finally, the push cylinder 5 connected to the corresponding clamping assembly 6 extends, pushing the clamping assembly 6 and the fixed drill and milling cutter together to the outside of the opening 11, so that the subsequent tool change mechanism can complete the gripping and replacement operation of the drill and milling cutter. The whole process does not require manual intervention, and the tool change efficiency and accuracy are effectively guaranteed.

[0017] Specifically, for the above scheme, refer to the appendix. Figure 2As shown, the door assembly 2 includes two guide rails 21 vertically and symmetrically arranged on both sides of the opening 11. A stop door 22 is slidably fitted on both guide rails 21, and the stop door 22 is connected to a telescopic cylinder 23 disposed on the outer shell 1, so that the telescopic cylinder 23 extends to close the stop door 22 to the opening 11, and conversely, the telescopic cylinder 23 retracts to move the stop door 22 away from the opening 11 and open the opening 11.

[0018] In the design, the door assembly 2 is guided by the vertically symmetrical guide rails 21 on both sides of the opening 11. Its movement trajectory is restricted by the sliding cooperation with the stop door 22. The telescopic cylinder 23 on the outer shell 1 provides power. When the telescopic cylinder 23 extends, it drives the stop door 22 to move vertically upward along the guide rail 21, completely covering the opening 11 to achieve closure and isolate impurities. When changing tools, the telescopic cylinder 23 retracts, pulling the stop door 22 to move vertically downward along the guide rail 21 away from the opening 11, opening the opening 11 for the drill and milling cutter to enter and exit. After changing tools, the telescopic cylinder 23 extends again to reset and close the stop door 22.

[0019] Specifically, for the above scheme, refer to the appendix. Figure 2 As shown, the clamping assembly 6 includes a mounting base 61 connected to the push cylinder 5. The mounting base 61 is provided with a limiting seat 62. Clamping plates 63 are symmetrically arranged on both sides of the limiting seat 62. Each of the two clamping plates 63 is connected to the mounting base 61 through a rotating shaft 64. A spring 65 is connected between the tail ends of the two clamping plates 63 so that the clamping ends of the two clamping plates 63 are elastic, which facilitates the placement of the drill and milling cutter.

[0020] In this design, the elastic force of the spring 65 enables the clamping ends of the two clamping plates 63 to open and close elastically, facilitating the insertion of the drill and milling cutter. This avoids the misfit or jamming problems caused by traditional fixed clamping, while also providing a stable fixation of the drill and milling cutter through elastic clamping, thus meeting the needs for drill and milling cutter storage and pushing.

[0021] In the above solution, to adapt the push cylinder 5 to push the drill cutter to the appropriate position, please refer to the attached diagram. Figure 3 and attached Figure 4 As shown, the push cylinder 5 is mounted on the mounting frame 4 via an adjustment assembly 7, allowing for fine-tuning of the forward distance of the push cylinder 5. Specifically, the adjustment assembly 7 includes a slide rail 71 horizontally mounted on the mounting frame 4, with a slider 72 slidably fitted on the slide rail 71 for mounting the push cylinder 5, and the slider 72 is connected to the slide rail 71 via a positioning bolt 73.

[0022] In the solution, the adjustment component 7 is based on the slide rail 71 horizontally mounted on the mounting bracket 4. The slider 72 of the push cylinder 5 is slidably mounted on the slide rail 71. By pushing the slider 72 to slide along the slide rail 71, the initial position of the push cylinder 5 can be adjusted, and its forward distance can be finely adjusted. After the adjustment is in place, the slider 72 is fixed to the slide rail 71 with the positioning bolt 73, which can lock the position of the push cylinder 5 and meet the precise distance requirements of the drill and milling cutter push.

[0023] In the above scheme, considering the ease of maintenance and repair of the internal components of the outer casing 1, therefore; In one embodiment, specifically, refer to the appendix. Figure 5 As shown, the top of the outer casing 1 is open and equipped with a cover plate 12 for mounting the drive motor 3, and the cover plate 12 is connected to the outer casing 1 by fastening bolts 13. In daily use, the cover plate 12 can securely mount the drive motor 3 and close the top of the outer casing 1 to ensure the safety of internal components; when maintenance and repair are required, the cover plate 12 can be removed by removing the fastening bolts 13, directly exposing the internal space of the outer casing 1 without disassembling the overall structure, which greatly reduces the difficulty of maintenance operations and improves maintenance efficiency.

[0024] In another embodiment, specifically, refer to the appendix. Figure 6 As shown, the top of the outer casing 1 is open and equipped with a cover plate 12 for mounting the drive motor 3. Two lifting cylinders 14 connected to the cover plate 12 are also vertically mounted on the outer casing 1. In daily use, the cover plate 12 can stably support the drive motor 3 and close the top of the outer casing 1 to protect the internal components. When maintenance or repair is required, the lifting cylinders 14 extend to automatically raise the cover plate 12, directly opening the top space of the outer casing 1. There is no need for manual disassembly and handling of the cover plate 12, making operation more convenient and labor-saving, improving maintenance efficiency, and avoiding the risk of bumps and damage when manually handling the cover plate 12.
