Description

Technical Field

[0001] This utility model relates to the field of gantry robot technology, specifically a gantry three-axis flat guide rail gantry robot. Background Technology

[0002] In modern industrial automation, gantry robots are widely used in material handling, parts assembly, and machine tool loading and unloading processes due to their stable structure, high motion precision, and large workspace. In particular, gantry robots with a gantry structure can achieve large-scale, high-precision three-dimensional spatial motion control through X, Y, and Z axis linkage, meeting the automation needs of complex industrial scenarios.

[0003] Currently, traditional gantry robots typically use a fixed-spacing gantry structure during installation. When the pre-set mounting hole positions on the ground in the actual installation environment do not match the gantry base, it is necessary to re-process the mounting foundation or customize a gantry of special dimensions. This not only increases installation costs and time but also limits the rapid deployment and adaptability of the equipment in different work scenarios. Utility Model Content

[0022] 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.

[0023] like Figure 1-4 As shown, this utility model provides a technical solution:

[0024] A gantry robot with three axes and flat guide rails includes two gantry frames 1. X-axis electric slide rails 2 are fixedly connected to the top of each gantry frame 1. A Y-axis electric slide rail 3 is positioned between the two X-axis electric slide rails 2. Both ends of the Y-axis electric slide rail 3 are fixedly connected to the sliders of the two X-axis electric slide rails 2. A Z-axis electric slide rail 4 is positioned on the front of the Y-axis electric slide rail 3, and its back is fixedly connected to the slider of the Y-axis electric slide rail 3. Flat guide rails 18 are symmetrically fixedly connected to both sides of the front of the Z-axis electric slide rail 4. Limiting blocks 19 are fixedly connected to the sliders of the Z-axis electric slide rail 4. Rollers 20 that cooperate with the flat guide rails 18 are rotatably connected to both ends of the limiting blocks 19 via bearings. A fixing seat 21 is fixedly connected to the front of the limiting blocks 19. A U-shaped frame 5 is fixedly connected to the bottom of the gantry frame 1. A mounting seat 6 is positioned at the bottom of the U-shaped frame 5. The mounting seat 6 is positioned between the U-shaped frame 5 and the mounting seat 6. A horizontal fine-tuning mechanism is provided, which includes a linear guide rail 7 horizontally fixedly connected to the middle of the top of the mounting base 6, and a rotating rod 8 rotatably connected to the middle of the U-shaped frame 5 via bearings. A movable groove 9 is provided in the middle of the top of the linear guide rail 7. A rack 10 is fixedly connected to the right wall of the movable groove 9. A gear 11 that meshes with the rack 10 is fixedly connected to the bottom of the rotating rod 8. The top of the rotating rod 8 extends into the interior of the gantry frame 1 and is fixedly connected to a worm gear 12. A handwheel 13 is rotatably connected to the outer side of the bottom of the gantry frame 1 via bearings. A worm 14 that meshes with the worm gear 12 is fixedly connected to the output shaft of the handwheel 13. The horizontal fine-tuning mechanism also includes rollers 15 rotatably connected to the four corners of the inner wall of the U-shaped frame 5 via bearings. Bosses 16 are fixedly connected to the outer sides of both ends of the linear guide rail 7. The rollers 15 roll in contact with the surface of the bosses 16. Scale bars 17 are evenly distributed on both sides of the top of the linear guide rail 7.

[0025] In this embodiment, the handwheel 13, worm gear 14, worm wheel 12, rotating rod 8, gear 11 and rack 10 are used in combination to achieve precise fine adjustment of the position of the gantry frame 1. This solves the problem that the traditional gantry frame must be strictly matched with the preset installation hole position on the ground during installation, enabling the equipment to quickly adapt to different installation environments and significantly improving installation efficiency and site adaptability.

[0026] Furthermore, the coordinated use of the linear guide rail 7, the boss 16, and the roller 15 ensures the smooth movement and precise positioning of the gantry 1 during the lateral adjustment process, solving the problems of jamming and positional deviation that are prone to occur during the adjustment of traditional gantry frames, and improving the motion accuracy and long-term working stability of the equipment.

[0027] Working principle: Two gantry frames 1 are fixed to the ground via U-shaped frames 5 and mounting bases 6 at their bottom ends, which are pre-drilled in the mounting holes. Once the mounting bases 6 are fixed to the ground, if it is necessary to adjust the lateral spacing between the two gantry frames 1, the handwheel 13 can be turned to rotate the worm gear 14. The worm gear 14 drives the worm wheel 12 to rotate, causing the rotating rod 8 to rotate synchronously. The gear 11 at the bottom of the rotating rod 8 meshes with the rack 10 in the movable groove 9 of the linear guide rail 7 fixed on the mounting base 6, thereby driving the U-shaped frame 5 and the gantry frame 1 above it to move along the linear guide rail 7 horizontally. The robot moves in one direction to achieve precise adjustment of the distance between the two gantry frames 1. At the same time, the rollers 15 at the four corners of the inner wall of the U-shaped frame 5 roll in contact with the bosses 16 at both ends of the linear guide rail 7 to ensure smooth movement. The scale bar 17 at the top of the linear guide rail 7 provides a precise reference for the distance adjustment. After the distance between the gantry frames 1 is adjusted to the correct position, the X-axis electric slide rail 2 is fixedly connected to the top of the gantry frame 1, and the installation and positioning of the whole machine is finally completed. This enables the robot to adapt to the installation requirements of different working scenarios and ensures the precise coordination of the X, Y and Z axis movements.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
