Description

Technical Field

[0001] This utility model relates to the field of machine tool component technology, and more specifically, to a bridge-type gantry beam structure for CNC machine tools. Background Technology

[0002] Gantry CNC machine tools, also known as gantry machining centers, are milling machines with a gantry frame and a horizontal long bed. Gantry CNC machine tools can use one or more milling cutters to process workpieces simultaneously, offering high machining accuracy and production efficiency. They are suitable for machining large workpieces' planar and inclined surfaces in batch and mass production, and can also machine spatial curved surfaces and some specific parts. The bridge-type crossbeam is one of the main components of this type of CNC machine tool. Existing crossbeam structures are relatively cumbersome to install, resulting in low convenience and affecting the efficiency of CNC machine tool installation and subsequent maintenance. Therefore, designing a bridge-type gantry crossbeam structure for CNC machine tools has become a problem we need to solve. Utility Model Content

[0003] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide a bridge-type gantry beam structure for CNC machine tools. By setting spherical guide members, the beam is lifted and inserted into the top of the frame. After entering the frame, the guide members gradually slide to the bottom to complete positioning, thereby improving the convenience of beam installation and solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bridge-type gantry beam structure for a CNC machine tool, comprising a beam, a fixing bolt inserted inside the beam, a frame connected to the outer side of the fixing bolt, the frame being located at the bottom of the beam, a connecting block slidably connected inside the beam, a connecting bolt inserted inside the connecting block, a spherical guide connected to the outer side of the connecting bolt, the spherical guide being located at the bottom of the beam and inserted inside the frame, and a limit post fixedly installed at the bottom of the connecting block, the limit post being inserted inside the spherical guide.

[0005] In a preferred embodiment, a first oil groove is fixedly installed on the top of the crossbeam, and a first slide rail is fixedly installed on the inner side of the first oil groove.

[0006] In a preferred embodiment, a second oil groove is provided on one side of the crossbeam, and a second slide rail is fixedly installed on the inner side of the second oil groove.

[0007] In a preferred embodiment, a limiting member is fixedly installed on one side of the crossbeam, and a drive screw is rotatably connected to the inner side of the limiting member.

[0008] In a preferred embodiment, a drive motor is fixedly mounted on one side of the crossbeam, and the drive screw is fixedly mounted on the output end of the drive motor.

[0009] In a preferred embodiment, the beam is internally fitted with reinforcing ribs.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model, by setting up spherical guides, allows for easy installation of the crossbeam. By installing spherical guides on both sides of the bottom of the crossbeam and lifting the crossbeam, the spherical guides are inserted into the interior of the crossbeam. The smooth spherical surface of the spherical guides allows them to slide down to the bottom after entering the frame, thus aligning with the center point of the frame. This facilitates convenient positioning of the crossbeam, which can then be fixed by installing multiple fixing bolts, thereby improving the ease of crossbeam installation.

[0016] 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.

[0017] Refer to the instruction manual appendix Figure 1-3 ,like Figure 1As shown, an embodiment of this utility model discloses a bridge-type gantry beam structure for a CNC machine tool, comprising a beam 1, a fixing bolt 2 inserted inside the beam 1, a frame 3 threadedly connected to the outer side of the fixing bolt 2, the frame 3 being located at the bottom of the beam 1, a connecting block 4 slidably connected inside the beam 1, a connecting bolt 5 inserted inside the connecting block 4, a spherical guide 6 threadedly connected to the outer side of the connecting bolt 5, the spherical guide 6 being located at the bottom of the beam 1 and inserted inside the frame 3, a limiting post 7 fixedly installed at the bottom of the connecting block 4, the limiting post 7 being inserted inside the spherical guide 6, and a first oil groove 8 fixedly installed at the top of the beam 1. The first oil groove 8 allows lubricating oil to be added, facilitating lubrication of the slide after installation. A second oil groove 11 is similarly provided. The first oil groove 8 has a first slide rail 9 fixedly installed on its inner side. The first slide rail 9, together with the second slide rail 10, can limit the installation of the slide block during later installation. A second oil groove 11 is opened on one side of the crossbeam 1. The second slide rail 10 is fixedly installed on the inner side of the second oil groove 11. A limit member 13 is fixedly installed on one side of the crossbeam 1. A drive screw 14 is rotatably connected to the inner side of the limit member 13. The drive screw 14 and the drive motor 15 are set together so that the slide block can be driven after the slide block is installed. A drive motor 15 is fixedly installed on one side of the crossbeam 1. The drive screw 14 is fixedly installed at the output end of the drive motor 15. A reinforcing rib 12 is fixedly installed inside the crossbeam 1. The reinforcing rib 12 can reduce the overall weight of the crossbeam 1 while increasing its strength.

[0018] It should be noted that during the installation of the crossbeam 1, the connecting block 4 is placed inside the crossbeam 1, allowing the limiting post 7 to be inserted into the spherical guide 6. The spherical guide 6 is then fixed to the bottom of the crossbeam 1 by connecting bolts 5. After installing the spherical guide 6 on both sides of the crossbeam 1, the crossbeam 1 is lifted, allowing the spherical guide 6 to be inserted into the top of the frame 3. At this point, the spherical guide 6 contacts the inner side of the frame 3. Because the spherical guide 6 is spherical, it will gradually slide to the bottom after entering the frame 3, ensuring the center of the spherical guide 6... Aligning the point with the frame 3 improves the ease of positioning the crossbeam 1. At this time, multiple fixing bolts 2 are installed to connect the crossbeam 1 to the frame 3, completing the fixation. When disassembling the crossbeam 1, the connecting bolts 5 are removed and the connecting block 4 is separated from the inside of the crossbeam 1, thereby causing the spherical guide 6 to lose connection with the crossbeam 1. Then, the multiple fixing bolts 2 are removed, so that the crossbeam 1 can be removed. This avoids lifting the crossbeam 1 too high, which would increase the difficulty of disassembly. This achieves the purpose of convenient positioning of the crossbeam 1 during installation, improving the ease of installation, and also improving the ease of disassembling and assembling the crossbeam 1.

[0019] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
