Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for gantry milling machines, and in particular to a rapid linear tool changer. Background Technology

[0002] As large-scale machining equipment, gantry milling machines often require multiple tools to operate alternately. Traditional tool changing relies on expensive chain-type or disc-type tool magazines. On the one hand, the cost of such tool magazines is usually tens of thousands of yuan or more, and they require complex electrical wiring connections and signal matching with the machine tool control system, resulting in a long installation and debugging cycle (3-5 days). On the other hand, chain / disc tool magazines have complex structures, and the tool changing process requires multiple steps of "tool removal-rotation-positioning-tool insertion", with a tool changing time of ≥15 seconds, which can easily affect machining efficiency due to mechanical jamming.

[0003] To reduce costs, some small businesses use manual tool changing, which not only takes 1-2 minutes but also easily leads to decreased machining accuracy due to tool holder installation errors. Current technology lacks a low-cost, easy-to-install, and quick-change solution, making it difficult to meet the high-efficiency machining needs of small and medium-sized enterprises using gantry milling machines.

[0004] Therefore, those skilled in the art have provided a rapid linear tool changer to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a rapid linear tool changer. This device allows for the assembly and use of the tool holder and gantry milling machine via positioning pins and connecting bolts, eliminating the need for wiring connections and shortening installation and debugging time. It solves the problems of "complex installation and long cycle" in traditional tool magazines. The overall design adopts "mechanical positioning + program adaptation," eliminating the need for additional electrical wiring and reducing costs for small and medium-sized enterprises. Furthermore, the linear tool change path is short and there is no rotational movement, effectively reducing machining auxiliary time, improving equipment utilization, and supporting disassembly at any time for flexible switching of machining scenarios.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rapid linear tool changer includes a gantry milling machine and a tool position bracket. The tool position bracket is detachably mounted on the gantry milling machine. The gantry milling machine has multiple pre-reserved slots inside. A stop block is slidably mounted on the upper end of the gantry milling machine at the corresponding pre-reserved slot. Multiple claw slots are equidistantly mounted on the upper end of the gantry milling machine. An elastic chuck is detachably mounted on the upper end of the gantry milling machine at the corresponding claw slot. A pneumatic push rod is fixedly mounted on one side of the gantry milling machine at the corresponding pre-reserved slot.

[0008] The above technical solution enables the tool holder to be assembled and used with the gantry milling machine through positioning pins and connecting bolts, eliminating the need for wiring connections and shortening installation and debugging time. This solves the problems of "complex installation and long cycle" of traditional tool magazines. The overall design adopts "mechanical positioning + program adaptation", eliminating the need for additional electrical wiring and reducing costs for small and medium-sized enterprises. At the same time, the linear movement tool changing path is short and there is no rotation, effectively reducing machining auxiliary time, improving equipment utilization, and supporting disassembly at any time, which facilitates flexible switching of machining scenarios.

[0009] Furthermore, the lower end of the gantry machine tool is provided with multiple screw holes at equal intervals, and each screw hole on the gantry machine tool is provided with a connecting bolt threaded thereon. The screw holes at the lower ends of the multiple connecting bolts are threadedly connected to the inside of the corresponding stop blocks.

[0010] The above technical solution enables rapid alignment of the tool holder by connecting bolts and stops, without the need to adjust the installation reference throughout the process.

[0011] Furthermore, each of the multiple stops is threaded with a positioning pin, and the multiple positioning pins pass through the corresponding stop and are threaded into the reserved slot.

[0012] The tool holder can be fixed by using the above technical solution, through the positioning pin and the reserved slot.

[0013] Furthermore, each of the multiple elastic claws is provided with a through hole, and each of the multiple elastic claws is provided with a disassembly bolt at the upper end of the corresponding through hole, and the lower end of each of the multiple disassembly bolts passes through the corresponding through hole and the tool holder.

[0014] The above technical solution allows for the replacement of the elastic jaws by disassembling and assembling bolts, further improving the clamping of cutting tools and reducing cost consumption.

[0015] Furthermore, the tool holder is made of aluminum alloy frame, and the surface of the tool holder is hard anodized.

[0016] The above technical solutions, using aluminum alloy materials and hard anodizing treatment, can reduce the weight of the tool holder, reduce the physical exertion of the installer, and improve the wear resistance of the tool holder.

[0017] This utility model has the following beneficial effects:

[0018] This utility model proposes a rapid linear tool changer. This device can be assembled and used between the tool holder and the gantry milling machine through positioning pins and connecting bolts, without the need for wiring connections. The installation and debugging time is short, solving the problem of "complex installation and long cycle" of traditional tool magazines.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Reference Figure 1-5 This utility model provides a specific implementation method:

[0028] A rapid linear tool changer includes a gantry milling machine 1 and a tool holder 2. The tool holder 2 is detachably mounted on the gantry milling machine 1. The gantry milling machine 1 has multiple pre-drilled slots 7. A stop 3 is slidably mounted on the upper end of the gantry milling machine 1 at the corresponding pre-drilled slot 7. Multiple tool claw slots 8 are equidistantly arranged on the upper end of the gantry milling machine 1. An elastic chuck 9 is detachably mounted inside the upper end of the gantry milling machine 1 at the corresponding tool claw slot 8. A pneumatic push rod 12 is fixedly mounted on one side of each pre-drilled slot 7 inside the gantry milling machine 1, and is connected via a positioning pin 6 and... The connecting bolt 4 enables the assembly and use of the tool holder 2 and the gantry machine tool 1 without the need for wiring connections. This shortens installation and debugging time, solving the problems of "complex installation and long cycle" associated with traditional tool magazines. The overall design adopts "mechanical positioning + program adaptation," eliminating the need for additional electrical wiring and reducing costs for small and medium-sized enterprises. Furthermore, the linear tool change path is short and involves no rotation, effectively reducing auxiliary processing time and improving equipment utilization. It also supports easy disassembly for flexible switching between processing scenarios. Multiple screw holes 5 are equidistantly spaced at the lower end of the gantry machine tool 1. On the machine tool 1, connecting bolts 4 are threaded at the corresponding screw holes 5. The lower ends of the connecting bolts 4 are threaded into the corresponding stop blocks 3. The tool position support 2 can be quickly aligned through the connecting bolts 4 and the stop blocks 3 without adjusting the installation reference. Locating pins 6 are threaded on the multiple stop blocks 3. The multiple locating pins 6 pass through the corresponding stop blocks 3 and are threaded into the reserved slots 7. The tool position support 2 can be fixed through the locating pins 6 and the reserved slots 7. Through holes 11 are opened on the multiple elastic jaws 9. Multiple elastic jaws 9 are threaded with mounting bolts 10 at their upper ends and corresponding through holes 11. The lower ends of the mounting bolts 10 all penetrate the corresponding through holes 11 and the tool holder 2. The elastic jaws 9 can be replaced by the mounting bolts 10, which further facilitates tool clamping and reduces cost wear. The tool holder 2 is made of aluminum alloy frame and the surface of the tool holder 2 is hard anodized. The use of aluminum alloy and hard anodizing reduces the weight of the tool holder 2, reduces the physical burden on the installer, and improves the wear resistance of the tool holder 2.

[0029] Working Principle: During installation, the tool position bracket 2 is first placed on the gantry machine tool 1. Then, connecting bolts 4 are used to connect the tool position bracket 2 to the stop block 3. Next, positioning pins 6 are inserted into the pre-drilled slots 7 to secure the tool position bracket 2 to the gantry machine tool 1, achieving rapid centering without requiring any adjustment of the installation reference. In use, the gantry machine tool 1 program is edited to set the linkage logic of "tool change trigger command - tool position bracket 2 movement distance - spindle positioning angle," while simultaneously setting the spindle orientation parameters. When a tool change is needed, the spindle moves to the tool change position, and the target tool is delivered via the X and Y axes of the worktable. The tool is positioned directly below the spindle, and the spindle descends to complete the tool removal / insertion action. The tool is clamped by the elastic jaws 9. This enables the assembly and use of the tool holder 2 and the gantry machine tool 1, as well as the rapid tool change. Installation requires no wiring connection, and the debugging time is short, solving the problem of "complex installation and long cycle" of traditional tool magazines. The overall design adopts "mechanical positioning + program adaptation", which does not require additional electrical wiring, reducing the cost requirements for small and medium-sized enterprises. At the same time, the linear movement tool change path is short and there is no rotation, which effectively reduces the machining auxiliary time, improves the equipment utilization rate, and supports disassembly at any time, making it easy to flexibly switch machining scenarios.
