[0002] As a large-scale, high-precision CNC machining equipment, the gantry machining center occupies a pivotal position in modern manufacturing. It is mainly used for milling, boring, and tapping various large and complex-shaped workpieces. With its unique gantry frame structure, it can bear heavy workpieces and provide stable support for the machining process, which greatly improves production efficiency and product machining accuracy. It plays a key role in promoting the development of the manufacturing industry towards high-end and intelligent manufacturing.

[0003] The cantilevered feed device in a gantry machining center is a key component responsible for the precise transport of cutting tools or workpieces. Installed cantilevered on one or both sides of the gantry frame, it has the ability to move flexibly in multiple coordinate axes. Driven by a motor, the lead screw and guide rails achieve precise positioning and feed motion of the cutting tool or workpiece in the X, Y, and Z axes. Its function is to accurately deliver the cutting tool to the workpiece's machining area and perform cutting operations at an appropriate speed and feed rate according to the machining process requirements, thereby ensuring the continuity and accuracy of the machining process. This directly impacts the overall machining quality and efficiency of the gantry machining center.

[0004] The existing feed device of the gantry machining center is installed on the gantry frame. When feed operation is required, due to the irregular shape of the workpiece, it is difficult for the feed device to flexibly adjust the tool position in a limited space. In the existing technology, the operating range of the feed device is increased by adding a moving slide rail to the feed device, so that it can be used for more workpieces. However, in actual use, when machining large workpieces, the feed device on the front side of the gantry frame cannot machine the side of the workpiece, resulting in a machining blind zone.

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.

[0032] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a cantilevered feed device for a gantry machining center, comprising a base 1, which provides stable support for the entire device, and a transmission belt 14, which transmits power and drives related components to move. The base 1 has a U-shaped frame 3 fixedly connected to both its left and right sides. The U-shaped frame 3 connects and supports other components. Lifting components are provided at both ends of the front side of the U-shaped frame 3, which can adjust the height of related components. Crossbars 8 are fixedly connected to the front sides of both lifting components, which connect and fix other parts. Moving slots 9 are provided on adjacent sides of the two crossbars 8, providing installation and rotation space for components such as rotating rods. The rear ends of the two crossbars 8 on opposite sides are fixedly connected to... A second motor 10 is fixedly connected to the rotating rod 11, which provides rotational power to the rotating rod 11. The output ends of both second motors 10 pass through the moving slot 19 and are fixedly connected to the rotating rod 11. The rotating rod 11 transmits the power of the second motor 10 to the rotating wheel 13. A second rotating rod 12 is rotatably connected to the front side of the interior of both moving slots 19. The second rotating rod 12, in conjunction with the rotating rod 11, drives the rotating wheel 13 to rotate. The outer walls of the rotating rod 11 and the second rotating rod 12 are fixedly connected to the rotating wheel 13. The rotating wheel 13 drives the transmission belt 14 to move by rotating. The outer walls of the two rotating wheels 13 are connected by the transmission belt 14. The transmission belt 14 can move horizontally under the drive of the rotating wheel 13. A U-shaped plate 15 is fixedly connected to the top of the transmission belt 14. The U-shaped plate 15 is used to install the third motor 16 and the blade. The tool 19 has components such as 19. A motor 16 is fixedly connected to the front side of the U-shaped plate 15, providing power for the rotation of the tool 19. The output end of the motor 16 passes through the U-shaped plate 15 and is fixedly connected to a rotating shaft 17. The rotating shaft 17 transmits the power of the motor 16 to the drive gear 18. The drive gear 18 is fixedly connected to the outer wall of the rotating shaft 17. The drive gear 18 drives the tool 19 to rotate by meshing with a half gear 20. The tool 19 is rotatably connected to the left side of the U-shaped plate 15 and is used for machining the workpiece. A half gear 20 is fixedly connected to the right side of the tool 19. The half gear 20 cooperates with the drive gear 18 to achieve intermittent rotation of the tool 19. The half gear 20 meshes with the drive gear 18 to complete the power transmission, causing the tool 19 to rotate intermittently. The base 1 is rotated in a specific manner. A placement mechanism 2 is provided on the top of the base 1. The placement mechanism 2 is used to place the workpiece and provides a stable placement platform for the workpiece. The lifting component includes a sliding groove 4, which provides guidance for the movement of the sliding block 7. Two sliding grooves 4 are respectively opened on the left and right ends of the front side of the U-shaped frame 3, limiting the movement trajectory of the sliding block 7. Motors 5 are fixedly connected to the top left and right sides of the U-shaped frame 3. Motors 5 provide power for the rotation of the threaded rod 6. The output ends of the two motors 5 pass through the corresponding sliding grooves 4 and are fixedly connected to the threaded rod 6. The threaded rod 6 drives the sliding block 7 to move up and down by rotating. The outer walls of the two threaded rods 6 are threaded with the sliding block 7. The sliding block 7 drives the crossbar 8 component to lift and lower.

[0033] Specifically, when motor 5 starts, it drives the threaded rod 6 to rotate. Since the sliding block 7 is threadedly connected to the threaded rod 6, the sliding block 7 will move up and down along the sliding groove 4, thereby realizing the lifting action of the lifting component. At the same time, the crossbar 8 will also rise and fall. After motor 10 starts, the rotating rod 11 rotates, driving the rotating wheel 13 to rotate. Then, through the transmission belt 14, the rotating rod 12 and the rotating wheel 13 will rotate. At this time, the transmission belt 14 moves under the drive of the rotating wheel 13. The U-shaped plate 15 fixedly connected to the top of the transmission belt 14 will move horizontally with the movement of the transmission belt 14. Motor 16 is located in front of the U-shaped plate 15. When motor 16 starts, it drives the drive gear 18 to rotate, which in turn drives the half gear 20 that meshes with it to rotate, so that the tool 19 can be adjusted in angle, realizing multi-directional processing operation of the workpiece.

[0034] Reference Figure 2 and Figure 5 The placement mechanism 2 includes a movable platform 201, which carries the workpiece and allows for positional movement. The bottom of the movable platform 201 is slidably connected to the top of the base 1, enabling the movable platform 201 to move horizontally on the base 1. Movable blocks 203 are fixedly connected to the left and right sides of the bottom of the movable platform 201. The movable blocks 203 cooperate with the second movable groove 202 to guide the movement direction of the movable platform 201. The top left and right sides of the base 1 are provided with the second movable groove 202, which provides a moving track for the movable blocks 203. A fourth motor 204 is fixedly connected to the bottom of the movable platform 201. The fourth motor 204 is a rotating column 205. The rotation of the placement tray 206 is powered by the output end of the motor 204, which passes through the mobile platform 201 and is fixedly connected to the rotating column 205. The rotating column 205 transmits the power of the motor 204 to the placement tray 206. The top of the rotating column 205 is fixedly connected to the placement tray 206, which is used to place the workpiece for processing, facilitating the processing operation of the workpiece. The top of the mobile platform 201 is provided with a limiting groove 28, which is used to limit the rotation range and center position of the placement tray 206. The bottom of the placement tray 206 is fixedly connected to a limiting ring 29, which cooperates with the limiting groove 28 to ensure the stability of the placement tray 206 when it rotates.

[0035] Specifically, the movable blocks 203 fixedly connected to the left and right sides of the bottom of the movable platform 201 cooperate with the movable slots 202 opened on the left and right sides of the top of the base 1. The movable blocks 203 can slide smoothly in the movable slots 202, thereby ensuring the stability and guidance of the movable platform 201 during the movement process. When the workpiece is placed on the placement plate 206, the motor 204 starts, and the rotating column 205 starts to rotate under the drive of the motor 204. By controlling the rotation angle of the rotating column 205 and the placement plate 206 through the motor 204, the processing position of the workpiece can be adjusted, which facilitates the processing operation and further expands the range of workpiece position adjustment of the placement mechanism 2. During the rotation of the placement plate 206, the limiting ring 29 rotates in the limiting groove 28, which restricts the horizontal displacement of the placement plate 206 and keeps it at a stable rotation axis.

[0036] Reference Figure 1 and Figure 2 A display 22 is fixedly connected to the upper right side of the U-shaped frame 3. The display 22 is used to display real-time information such as equipment operating parameters and processing progress. A protective shell 23 is fixedly connected to the outer wall of the display 22 to prevent the display 22 from being damaged by external impacts, scratches, etc. A switch 21 is fixedly connected to the lower right side of the U-shaped frame 3. The switch 21 is used to control the start and stop of the equipment and the power supply of each motor and the display 22. The switch 21 is electrically connected to motor 5, motor 10, motor 16, motor 204 and the display 22 respectively to realize the power control of each component. The left side of the U-shaped frame 3 is fixed A mounting plate 24 is connected to the U-shaped frame 3. The mounting plate 24 is used to install and fix the warning sign 25. The warning sign 25 is fixedly connected to the left side of the mounting plate 24. The warning sign 25 can display safety precautions, warning signs, etc. to the operators to prevent safety accidents. Two sliding grooves 26 are opened inside the left and right sides of the U-shaped frame 3. The sliding grooves 26 provide guidance and support for the movement of the slider 27. The left and right sides of the two sliding blocks 7 are fixedly connected to the sliders 27. The sliders 27 are used to cooperate with the sliding grooves 26 to enhance the stability of the sliding blocks 7 when moving. Multiple sliders 27 are slidably connected to the interior of the corresponding sliding grooves 26 to ensure that the sliding blocks 7 move up and down smoothly.

[0037] Specifically, the display 22 is used to display the equipment operating parameters in real time. The protective shell 23 fits tightly against the outer wall of the display 22, which can effectively prevent external collisions. Operators can conveniently turn on or off each motor and control the operation of the equipment by operating the switch 21. The mounting plate 24 securely connects the warning sign 25 to the left side of the U-shaped frame 3. The warning sign 25 is marked with equipment operation precautions and safety warning slogans to constantly remind operators to operate in accordance with regulations. When the sliding block 7 moves up and down along the sliding groove 4 under the drive of the threaded rod 6, the slider 27 slides synchronously in the sliding groove 26, providing additional guidance and support for the movement of the sliding block 7.

[0038] Working principle: When using the cantilever feed device of the gantry machining center, when motor 1 5 starts, it drives the threaded rod 6 to rotate. Since the sliding block 7 is threadedly connected to the threaded rod 6, the sliding block 7 will move up and down along the sliding groove 4, thereby realizing the lifting action of the lifting component. At the same time, the crossbar 8 will also rise and fall. After motor 2 10 starts, the rotating rod 11 rotates, driving the rotating wheel 13 to rotate, and then driving the rotating rod 2 12 and the rotating wheel 13 to rotate through the transmission belt 14. At this time, the transmission belt 14 moves under the drive of the rotating wheel 13. The U-shaped plate 15 fixedly connected to the top of the transmission belt 14 will move horizontally with the movement of the transmission belt 14. Motor 3 16 is located in front of the U-shaped plate 15. When motor 3 16 starts, it drives the drive gear 18 to rotate, and then drives the half gear 20 that meshes with it to rotate, so that the tool 19 can be adjusted in angle, realizing multi-directional machining operation of the workpiece.

[0039] Furthermore, the movable blocks 203 fixedly connected to the left and right sides of the bottom of the movable platform 201 cooperate with the movable slots 202 opened on the left and right sides of the top of the base 1. The movable blocks 203 can slide smoothly in the movable slots 202, thereby ensuring the stability and guidance of the movable platform 201 during the movement process. When the workpiece is placed on the placement plate 206, the motor 204 starts, and the rotating column 205 starts to rotate under the drive of the motor 204. By controlling the rotation angle of the rotating column 205 and the placement plate 206 through the motor 204, the processing position of the workpiece can be adjusted, which facilitates the processing operation and further expands the range of workpiece position adjustment of the placement mechanism 2.
