Description

Technical Field

[0001] This invention belongs to the field of gantry machine tool technology, specifically a gantry machine tool for processing large mechanical equipment. Background Technology

[0002] Gantry milling machines are widely used in large-scale machining, typically for processing heavy workpieces such as molds, aerospace components, and ship structures. Their design features give them high machining accuracy and stability, enabling them to meet complex and demanding machining tasks. A gantry milling machine usually consists of a crossbeam and two columns. The crossbeam spans across the top of the two columns, forming a "gate" structure. This design effectively improves the rigidity and stability of the machine tool, reducing vibration and deformation that may occur during machining. A spindle is usually mounted on the crossbeam, which can perform various cutting, milling, drilling, and other machining operations.

[0003] A Chinese invention patent, CN104972354B, discloses a gantry milling machine. The key technical features include: a bed, a crossbeam, a worktable, a vacuum chuck, a column, a machine head, a tool magazine, an X-axis slide, a protective mechanism, and a dust collection mechanism. The crossbeam is mounted to the bed via brackets at both ends, the worktable is mounted to the bed, and the vacuum chuck is mounted to the worktable. The column is mounted to the crossbeam, and the machine head is mounted to the column. The tool magazine is mounted to the brackets. The protective mechanism is mounted to the X-axis slide, covering the crossbeam, the column, and the brackets. This invention removes a large amount of dust generated during processing by using a dust collection mechanism, ensuring smooth processing and high precision. Furthermore, the vacuum chuck grips the workpiece tightly, reducing its height and preventing damage, while also facilitating the installation of the protective mechanism.

[0004] However, the above technologies often have the following drawbacks: it is not convenient to clean up the waste generated during the processing in a timely manner. It is necessary to wait until the processing is completed and then manually clean the machine tool table. The cleaning effect is relatively poor. Moreover, if too much material residue accumulates, the table may not be able to operate normally. The machine must be stopped for cleaning before processing can continue, which greatly affects production efficiency.

[0005] Therefore, the present invention provides a gantry milling machine for processing large-scale mechanical equipment. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

The adjustment assembly includes a first guide rail, the inside of which is fixedly connected to one end of the placement assembly. A stepper motor is fixedly installed on one side of the first guide rail. A rotating rod is fixedly connected to the output end of the stepper motor. Connecting parts are fixedly connected to both sides of the outer surface of the rotating rod. A connecting ring is rotatably connected to the middle of the outer surface of the rotating rod. A cylinder is fixedly connected to the lower surface of the connecting ring. A protective shell is fixedly connected to the outer surface of the cylinder. The water spray assembly includes a water supply pipe, both ends of which are fixedly connected to the inside of a connector. A high-pressure nozzle is fixedly installed in the middle of the outer surface of the water supply pipe. One end of the water supply pipe is rotatably connected to a water pump via a first bearing. A folded pipe is fixedly connected to the input end of the water pump.

[0008] The placement assembly includes a base, both ends of which are fixedly connected to the inner side of the first guide rail. A pad is fixedly connected to the upper surface of the base. A cavity is opened inside the base. A slot is opened on one side of the bottom wall of the cavity. A locking rod is locked inside the slot. A frame is fixedly connected to the top of the locking rod. A filter screen is fixedly connected inside the frame.

[0009] The positioning component includes a first slider, the outer surface of which is slidably connected to the interior of any T-slot. An extension frame is rotatably connected to the upper surface of the first slider via a second bearing. A hydraulic rod is fixedly connected to the lower surface of the extension frame, and a pressing plate is fixedly connected to the bottom end of the hydraulic rod.

[0010] An anti-slip pad is fixedly connected to the lower surface of the pressing plate, and an anti-slip groove is formed on the lower surface of the anti-slip pad.

[0011] The movable component includes a movable rail, the inner side of which is fixedly connected to one side of the base. A movable seat is slidably connected to the upper surface of the movable rail. A gantry frame is fixedly connected to the upper surface of the movable seat. Guide rods are slidably connected to both sides of the front surface of the movable seat.

[0012] The drive assembly includes a first drive motor, one side of which is fixedly mounted on one side of the moving rail. The output end of the first drive motor is fixedly connected to a first threaded rod, and one end of the first threaded rod is fixedly connected to a pulley. A belt is rotatably connected to the outer surface of the pulley.

[0013] The upper surface of the moving rail is provided with three sliding grooves. The inner part of the middle sliding groove is rotatably connected to the outer surface of the first threaded rod, while the inner parts of the two side sliding grooves are fixedly connected to the outer surface of the guide rod.

[0014] The processing assembly includes a second drive motor, the outer surface of which is fixedly mounted inside the mounting groove.

[0015] The beneficial effects of this invention are as follows: 1. The gantry milling machine tool for large-scale mechanical equipment processing described in this invention, through the setting of adjustment components and water spray components, starts the cylinder to drive the rotating rod to move up and down through the connecting ring. The first guide rail moves up and down synchronously to support the two ends of the rotating rod, thereby facilitating the adjustment of the height of the water supply pipe. This allows the high-pressure nozzle to cool and reduce dust on the processing parts when processing equipment of different heights. Then, an external power supply starts the stepper motor, and the rotating rod rotates accordingly. Through the connecting parts, it drives the water supply pipe to rotate, adjusting the spray angle of the high-pressure nozzle. Subsequently, the water pump is started to deliver water to the inside of the water supply pipe through the folded pipe, thus facilitating the cleaning of waste on the processing table at any time. This avoids excessive accumulation of material residue, which could prevent the worktable from operating normally and affect production efficiency. Furthermore, the thorough rinsing ensures a good cleaning effect.

[0016] 2. The gantry milling machine tool for large-scale mechanical equipment processing described in this invention, through a set placement component, allows waste debris flushed by a high-pressure nozzle to fall into the interior of the frame. A filter screen intercepts and filters the waste debris, and the filtered water is stored in the cavity inside the base. It can then be pumped back for use, which helps to save resources and reduce production costs. Furthermore, the frame is secured to the inner bottom wall of the cavity by a clamping rod, making it easy to remove the frame and filter screen as a whole, thereby cleaning the waste debris intercepted inside the filter screen. The operation is convenient and easy to use. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1: As Figures 1 to 7 As shown in the figure, a gantry milling machine for large mechanical equipment processing according to an embodiment of the present invention includes a placement component. The upper surface of the placement component is provided with a T-slot. The number of T-slots is several. A positioning component is slidably connected inside any T-slot. An adjustment component is fixedly connected to both ends of the placement component. A water spraying component is fixedly connected inside the adjustment component. A moving component is fixedly connected to both sides of the placement component. A driving component is fixedly installed in the middle of one side of the moving component. An installation groove is formed on the front surface of the moving component. A processing component is fixedly installed inside the installation groove. The adjustment assembly includes a first guide rail 1, which is fixedly connected to one end of the assembly. A stepper motor 2 is fixedly mounted on one side of the first guide rail 1. A rotating rod 3 is fixedly connected to the output end of the stepper motor 2. Connecting parts 4 are fixedly connected to both sides of the outer surface of the rotating rod 3. A connecting ring 5 is rotatably connected to the middle of the outer surface of the rotating rod 3. A cylinder 6 is fixedly connected to the lower surface of the connecting ring 5. A protective shell 7 is fixedly connected to the outer surface of the cylinder 6. When the cylinder 6 is started, it drives the rotating rod 3 to move up and down through the connecting ring 5. The first guide rail 1 moves up and down synchronously to support the two ends of the rotating rod 3, thereby facilitating the adjustment of the height of the water pipe 8. This allows the high-pressure nozzle 9 to cool and reduce dust on the processing parts when processing equipment of different heights. When the stepper motor 2 is started by an external power supply, the rotating rod 3 rotates accordingly. The water pipe 8 rotates through the connecting parts 4, and the spray angle of the high-pressure nozzle 9 is adjusted to facilitate the cleaning of the workbench. The water spray assembly includes a water supply pipe 8, with both ends of the outer surface of the water supply pipe 8 fixedly connected to the inside of the connector 4. A high-pressure nozzle 9 is fixedly installed in the middle of the outer surface of the water supply pipe 8. One end of the water supply pipe 8 is rotatably connected to a water pump 11 through a first bearing 10. A folded pipe 12 is fixedly connected to the input end of the water pump 11. When the water pump 11 is started, water is delivered to the inside of the water supply pipe 8 through the folded pipe 12, which facilitates the cleaning of waste on the processing table at any time, avoiding excessive accumulation of material residue, which would prevent the worktable from operating normally and affect production efficiency. Furthermore, the thorough rinsing ensures a good cleaning effect.

[0022] The placement component includes a base 13, both ends of which are fixedly connected to the inner side of the first guide rail 1. A pad 14 is fixedly connected to the upper surface of the base 13. A cavity is opened inside the base 13, and a slot is opened on one side of the bottom wall of the cavity. A locking rod 15 is locked inside the slot. A frame 16 is fixedly connected to the top of the locking rod 15. A filter screen 17 is fixedly connected inside the frame 16. Waste debris washed out by the high-pressure nozzle 9 falls into the interior of the frame 16. The filter screen 17 intercepts and filters the waste debris. The filtered water is stored inside the cavity of the base 13 and is pumped back by the water pump 11 for use, which saves resources and reduces production costs. The locking rod 15 locks the frame 16 to the inner bottom wall of the cavity, making it easy to remove the frame 16 and the filter screen 17 as a whole, thereby cleaning the waste debris intercepted inside the filter screen 17. The operation is convenient and easy to use.

[0023] Example 2: Figures 1 to 7 As shown in Example 1, another embodiment of the present invention is as follows: The positioning assembly includes a first slider 18, the outer surface of which is slidably connected to the inside of any T-slot. An extension frame 20 is rotatably connected to the upper surface of the first slider 18 via a second bearing 19. A hydraulic rod 21 is fixedly connected to the lower surface of the extension frame 20. A pressing plate 22 is fixedly connected to the bottom end of the hydraulic rod 21. After the workpiece to be processed is placed on the upper surface of the pad 14, the first slider 18 is slid to a suitable position inside the T-slot. The extension frame 20 is rotated above the workpiece via the second bearing 19. The hydraulic rod 21 is then activated to push the pressing plate 22 downward, thereby pressing and fixing the workpiece to be processed to prevent displacement during processing and reduce processing accuracy.

[0024] An anti-slip pad 23 is fixedly connected to the lower surface of the pressing plate 22. The lower surface of the anti-slip pad 23 has an anti-slip groove. The anti-slip pad 23 increases the friction between the pressing plate 22 and the workpiece to be processed, improves its fixed stability, and the anti-slip groove increases the anti-slip performance of the anti-slip pad 23.

[0025] The moving assembly includes a moving rail 24, the inner side of which is fixedly connected to one side of the base 13. A moving seat 25 is slidably connected to the upper surface of the moving rail 24, and a gantry frame 26 is fixedly connected to the upper surface of the moving seat 25. Guide rods 27 are slidably connected to both sides of the front surface of the moving seat 25. The moving seat 25 moves on the upper surface of the moving rail 24, thereby driving the gantry frame 26 to move, so that the spindle 36 is in the required position. The guide rods 27 limit the direction of movement of the moving seat 25 to avoid shaking during movement and affecting the machining accuracy.

[0026] The drive assembly includes a first drive motor 28, one side of which is fixedly mounted on one side of the moving rail 24. The output end of the first drive motor 28 is fixedly connected to a first threaded rod 29, and one end of the first threaded rod 29 is fixedly connected to a pulley 30. A belt 31 is rotatably connected to the outer surface of the pulley 30. When an external power source starts the first drive motor 28, the pulley 30 is driven to rotate through the first threaded rod 29, and the first threaded rod 29 in the moving rail 24 on the other side is driven to rotate through the belt 31. This causes the bottom ends on both sides of the portal frame 26 to slide synchronously on the outer surface of the first threaded rod 29, providing it with kinetic energy for movement.

[0027] The upper surface of the moving rail 24 is provided with three sliding grooves. The inner part of the middle sliding groove is rotatably connected to the outer surface of the first threaded rod 29, while the inner parts of the two side sliding grooves are fixedly connected to the outer surface of the guide rod 27. By setting three sliding grooves, the limiting area of ​​the moving rail 24 on the moving seat 25 is increased, thereby improving its stability during sliding.

[0028] The processing assembly includes a second drive motor 32, the outer surface of which is fixedly mounted inside the mounting slot. The output end of the second drive motor 32 is fixedly connected to a second threaded rod 33. The outer surface of the second threaded rod 33 is threadedly connected to a second sliding block 34. The front surface of the second sliding block 34 is fixedly connected to a second guide rail 35. The front surface of the second guide rail 35 is fixedly connected to a spindle 36. When an external power source is connected to start the second drive motor 32, the second threaded rod 33 drives the second sliding block 34 to move, so that the second guide rail 35 is in a suitable position. Then, the second guide rail 35 is started to drive the spindle 36 to move up and down to process the workpiece.

[0029] Working principle: First, after placing the workpiece on the upper surface of the pad 14, slide the first slider 18 to a suitable position inside the T-slot. The extension frame 20 is rotated above the workpiece via the second bearing 19. The hydraulic rod 21 is activated to push the pressing plate 22 downwards, thereby pressing and fixing the workpiece. The anti-slip pad 23 increases the friction between the pressing plate 22 and the workpiece, improving its stability. Next, the external power supply starts the first drive motor 28, which drives the pulley 30 to rotate via the first threaded rod 29. The belt 31 drives the first threaded rod 29 in the moving rail 24 on the other side to rotate, so that the bottom ends of both sides of the gantry frame 26 slide synchronously on the outer surface of the first threaded rod 29. The guide rod 27 limits the movement direction of the moving seat 25, so that the main shaft 36 is in the required position. Next, the external power supply starts the second drive motor 32, which drives the second sliding block 34 to move through the second threaded rod 33, so that the second guide rail 35 is in the appropriate position. Then, the second guide rail 35 is started to drive the main shaft 36 to move up and down to process the workpiece. At the same time, the cylinder 6 is started to drive the rotating rod 3 to move up and down through the connecting ring 5. The first guide rail 1 moves up and down synchronously to support the two ends of the rotating rod 3, so as to facilitate the adjustment of the height of the water pipe 8. This allows the high-pressure nozzle 9 to cool and reduce dust on the processing part when processing equipment of different heights. Then, the external power supply starts the stepper motor 2, and the rotating rod 3 rotates accordingly. Through the connecting piece 4, the water pipe 8 rotates to adjust the spray angle of the high-pressure nozzle 9. Then, the water pump 11 is started to deliver water to the folded pipe 12. Inside the water supply pipe 8, waste debris on the processing table can be easily cleaned off at any time. Finally, the waste debris washed off by the high-pressure nozzle 9 falls into the interior of the frame 16, where the filter screen 17 intercepts and filters the waste debris. The filtered water is stored in the cavity inside the base 13 and is pumped back by the water pump 11 for use, which helps to save resources and reduce production costs. The frame 16 is also secured to the inner bottom wall of the cavity by the clamping rod 15, making it easy to remove the frame 16 and the filter screen 17 as a whole, thereby cleaning the waste debris intercepted inside the filter screen 17.
