Description

Technical Field

[0001] This utility model relates to the field of gantry crane technology, and in particular to a high-mounted gantry bed structure. Background Technology

[0002] The elevated gantry bed structure includes a gantry beam, which is the core load-bearing and moving component spanning the machine tool gantry frame. Its main function is to support the Z-axis assembly and the laser cutting head, and drive them to perform high-precision linear motion along the X-axis of the machine tool. According to the patent application number CN202020581731.0, a gantry-type three-dimensional five-axis laser cutting machine's beam is disclosed, which includes a welded box-type beam body. Both ends of the beam body are equipped with mounting brackets for supporting the X-axis dual drive motors. The weight is greatly reduced, and the strength can meet the support requirements, thus meeting the needs of increasing machine tool operating speed.

[0003] The aforementioned device reduces the overall weight of the crossbeam by using a box-type beam structure. However, in actual use, due to the reduced weight of the crossbeam, the Z-axis assembly, laser cutting head, and dual drive motor installed on the side of the crossbeam still have a certain weight. This causes the crossbeam to generate additional bending moments due to the shift in the center of gravity when it moves, thereby reducing the stability of the crossbeam during movement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-bay gantry bed structure. It solves the technical problem that, due to the reduced weight of the crossbeam, the Z-axis assembly, laser cutting head, and dual drive motors mounted on the side of the crossbeam still have considerable weight. These components cause additional bending moments during crossbeam movement due to center of gravity shift, reducing the stability of the crossbeam during movement. This new structure solves the problems of heavy crossbeams and slow movement speed while ensuring a consistent center of gravity throughout the profile frame's movement, guaranteeing the profile frame remains in a pure translational state and improving its stability during movement.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a high-mounted gantry bed structure, including a main body of a crossbeam that slides on the top of the bed, the main body of the crossbeam including a profile frame, with mounting components at both ends of the profile frame, and a load-bearing component slidably connected to the profile frame; The mounting components include mounting plate one and mounting plate two symmetrically arranged on both sides of the profile frame. Horizontal rails are fixedly installed on the outer walls of both sides of the profile frame. The load-bearing components include load-bearing plate one and load-bearing plate two symmetrically arranged on both sides of the profile frame and slidably connected to the horizontal rails. A drive plate is fixedly connected to the top of load-bearing plate one and load-bearing plate two. The profile frame is internally equipped with reinforcing components.

[0006] Preferably, the profile frame has a wall thickness of -mm and an internal hollow structure.

[0007] Preferably, the mounting plate one and the mounting plate two are fixedly mounted on opposite sides and are fixedly connected to the profile frame, and a reinforcing plate inserted inside the profile frame is fixedly mounted between the two sets of connecting plates.

[0008] Preferably, a protective plate is vertically fixed around the perimeter of the first mounting plate and the second mounting plate, and a reserved through hole is provided at the connecting plate.

[0009] Preferably, the outer walls of the first bearing plate and the second bearing plate are respectively fixedly installed with fixing plates.

[0010] Preferably, the reinforcing component includes traction plates fixedly installed on the inner walls of both sides of the profile frame, multiple sets of stiffening plates fixedly installed between the two sets of traction plates, and inclined reinforcing ribs fixedly installed between adjacent sets of stiffening plates.

[0011] Preferably, the multiple sets of stiffeners are evenly distributed along the length of the profile frame.

[0012] By employing the above technical solution, this utility model provides a high-mounted gantry bed structure, which has at least the following beneficial effects: 1. This utility model uses a box-type beam structure made of high-strength steel welded into the profile frame, replacing existing castings and other structures. This significantly reduces weight while maintaining sufficient strength to support the beams. It effectively solves the problems of heavy beams and slow movement speed. Furthermore, by reserving and installing the same support components for the dual-drive motor and Z-axis components in the profile frame, it ensures that the center of gravity remains consistent throughout the frame's movement, completely offsetting the off-center load of the front motor and eliminating additional bending moments at the source. This ensures that the profile frame remains in a pure translational state, improving its stability during movement.

[0013] 2. This utility model improves the strength and rigidity of the entire profile frame by installing a reinforcing component inside the profile frame. The reinforcing component is composed of multiple high-strength steel ribs and reinforcing bars. It can reduce local stress in the profile frame, avoid stress concentration, achieve good stress distribution, and extend service life. Attached Figure Description

[0017] 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.

[0018] Example 1 Addressing the existing technical problem that, due to the reduced weight of the crossbeam, the Z-axis assembly, laser cutting head, and dual drive motors mounted on the sides of the crossbeam still possess considerable weight. This weight causes additional bending moments due to center of gravity shift during crossbeam movement, reducing stability. This embodiment provides a high-bay gantry bed structure that solves the problems of heavy crossbeams and slow movement speed while ensuring a consistent center of gravity throughout the profile frame's movement. This guarantees the profile frame remains in a pure translational state, improving stability during profile frame movement. Please refer to... Figure 1 - Figure 4 The elevated gantry bed structure includes a main beam 1 that slides on the top of the bed. The main beam 1 includes a profile frame 11. Mounting components 12 are provided at both ends of the profile frame 11. The mounting components 12 are used to support the X-axis dual drive motors and provide a power source for the sliding of the profile frame 11. A bearing component 13 is slidably connected to the profile frame 11. The bearing component 13 is used to mount the Z-axis component and the cutting head. The profile frame 11 is responsible for driving the Z-axis component and the cutting head to slide along the X-axis, and the bearing component 13 is responsible for driving the Z-axis component and the cutting head to slide along the Y-axis.

[0019] Because dual drive motors need to be installed on both sides of the front end of the profile frame 11 to ensure its movement, a bias towards the front end will occur during the movement of the profile frame 11. Without counterweight, the profile frame 11 will generate additional bending moment due to the shift in center of gravity during movement, reducing the stability of the profile frame 11 during movement. To solve the above problem, such as Figure 1 - Figure 4 As shown, the mounting assembly 12 includes mounting plate 121 and mounting plate 122 symmetrically arranged on both sides of the profile frame 11. A horizontal rail 2 is fixedly installed on the outer walls of both sides of the profile frame 11. The bearing assembly 13 includes bearing plate 131 and bearing plate 132 symmetrically arranged on both sides of the profile frame 11 and slidably connected to the horizontal rail 2. A drive plate 133 is fixedly connected to the top of bearing plate 131 and bearing plate 132. Mounting holes are respectively provided at mounting plate 121 and mounting plate 122 for fixing the dual-drive motor and counterweight. Mounting plate 121 and mounting plate 122 support the dual-drive motor and counterweight respectively, and the weight of the counterweight is the same as the weight of the dual-drive motor. This ensures that the center of gravity of the profile frame 11 is consistent during the overall movement, completely offsetting the off-center load of the front motor, eliminating additional bending moment from the source, ensuring that the profile frame 11 is always in a pure translational state, and improving the stability of the profile frame 11 during movement.

[0020] While increasing the movement speed of the profile frame 11 by reducing weight, it is necessary to ensure the overall rigidity of the profile frame 11, such as... Figure 3 As shown, the interior of the profile frame 11 is provided with a reinforcing component 3. The reinforcing component 3 can improve the overall rigidity while reducing weight by dispersing stress.

[0021] The profile frame 11 has a wall thickness of 3-8mm and an internal hollow structure. The mounting plate 1211 and the mounting plate 122 are fixedly installed on opposite sides and are fixedly connected to the profile frame 11. A reinforcing plate 1222 is fixedly installed between the two sets of connecting plates 1211 and is inserted inside the profile frame 11. The profile frame 11 is made of hollow high-strength cast aluminum or aluminum alloy profile, which can reduce weight compared to traditional steel. At the same time, the strength is improved through aging treatment. It can reduce the weight of the beam as much as possible while ensuring strength and rigidity, and provide a foundation for a greater speed increase.

[0022] Specifically, such as Figure 1 As shown, a protective plate 1223 is vertically fixed around the mounting plate 121 and mounting plate 122. A reserved through hole is opened at the connecting plate 1211, and a through hole is opened in the profile frame 11 to communicate with the two sets of mounting plates. This is used to connect the output end of the X-axis dual drive motor to realize the movement of the crossbeam. At the same time, the protective plate 1223 can protect the X-axis dual drive motor and ensure the smoothness and efficiency of the transmission.

[0023] Example 2 Based on Embodiment 1, since a support assembly 13 for supporting the Z-axis component and the cutting head needs to be installed at the profile frame 11, in order to further ensure the stability of the profile frame 11 during movement, such as... Figure 2 As shown, the device is also equipped with a first bearing plate 131 and a second bearing plate 132 that slide synchronously on both sides of the profile frame 11. The two sets of fixed plates 1311 are provided with mounting holes for the Z-axis component, the cutting head and the counterweight, respectively, to ensure that the weight on both sides of the profile frame 11 is consistent. The outer walls of the first bearing plate 131 and the second bearing plate 132 are respectively fixedly installed with fixed plates 1311. The first bearing plate 131 slides along the direction of the horizontal rail 2 through the built-in power component, driving the Z-axis component and the cutting head to move in the Y-axis direction.

[0024] Specifically, such as Figure 3 As shown, the reinforcing component 3 includes traction plates 31 fixedly installed on the inner walls of both sides of the profile frame 11. Multiple sets of stiffening plates 32 are fixedly installed between the two sets of traction plates 31. The stiffening plates 32 are preferably made of high-strength steel to achieve lightweight and high strength. An inclined reinforcing rib 33 is fixedly installed between two adjacent sets of stiffening plates 32. A reinforcing rib 33 is also welded between two adjacent stiffening plates 32. The reinforcing rib 33 can further improve the strength and rigidity of the entire profile frame 11. One side of the profile frame 11 is in contact with two adjacent stiffening plates 32, while the other side is in contact with the inner wall of the profile frame 11. This can reduce local stress, avoid stress concentration, achieve good stress distribution, and extend service life.

[0025] Multiple sets of stiffening plates 32 are evenly distributed along the length of the profile frame 11. Several stiffening plates 32 connected end to end are welded to the inside of the profile frame 11 in a zigzag manner to improve the strength and rigidity of the entire beam. The upper and lower edges of the stiffening plates 32 are in contact with the upper and lower surfaces of the inner wall of the profile frame 11, respectively. Several stiffening plates 32 are connected end to end and arranged in a zigzag manner inside the profile frame 11, which can reduce local stress, avoid stress concentration, achieve good stress distribution, and extend service life.
