Description

Technical Field

[0001] The utility model relates to the technical field of crossbeams, and more specifically, the utility model relates to a split crossbeam of a five-axis gantry machining center. Background Art

[0002] A gantry machining center refers to a machining center with a spindle axis perpendicular to the workbench, which is mainly suitable for machining large parts. As the carrier of the main components of the gantry machining center, the crossbeam needs to have the characteristics of large load-bearing capacity, good bending resistance, torsion resistance, compression resistance, and good vibration resistance.

[0003] Among them, the patent with the publication number CN218363301U discloses a split crossbeam of a five-axis gantry machining center, including a crossbeam body. The crossbeam body includes a first crossbeam and a second crossbeam arranged symmetrically. The first crossbeam and the second crossbeam have the same structure and screw fixed seats are arranged on the inner sides. A hollow sandwich is formed between the first crossbeam and the second crossbeam, and the sides with the screw fixed seats are arranged oppositely. A connecting plate for fixed connection is arranged at the end of the crossbeam body, and a fixed seat is arranged at the bottom of the crossbeam body;

[0004] When this structure is in use, the bending deformation of the crossbeam is reduced by the split crossbeam with a symmetrical structure. At the same time, the inner side of the crossbeam is a hollow structure, reducing the overall weight of the crossbeam. The load-bearing, compression resistance, and vibration resistance are improved through the Y-shaped reinforcing rib plates, improving the stability and accuracy of the gantry machining center. However, when this structure is in use, it is only a single specified beam body, which is not easy to ensure the accuracy during position adjustment during machining, and the single Y-shaped structure is not easy to relieve force, resulting in a relatively low anti-deformation performance of itself. Summary of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a split crossbeam of a five-axis gantry machining center, aiming to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A split crossbeam of a five-axis gantry machining center, including a bottom beam, and a strengthening and supporting component is arranged on the bottom beam;

[0007] The strengthening and supporting component includes a supporting beam arranged on the top of the bottom beam. Both ends of the bottom beam are rotatably connected with strengthening transverse axes, and supporting wheels are installed at both ends of each strengthening transverse axis through bolts. Guide rings are sleeved on the outer sides of the two supporting wheels, and side baffles are fixedly arranged on one side of each supporting wheel;

[0008] A first connecting concave block is arranged on the bottom beam and between the two strengthening transverse axes. The top of the first connecting concave block is installed with a first hydraulic rod through bolts, and the output end of the first hydraulic rod is installed with a second connecting concave block through bolts.

[0009] It can be seen that in the above technical solution, when the bottom beam displaces, it drives the supporting wheels to displace. The guide ring and the side baffle are used to guide and limit the displacement of the supporting wheels when they displace, ensuring the stability of the bottom beam and the supporting beam when moving on the gantry;

[0010] Optionally, in a possible implementation manner, the second connecting concave block is located at the bottom of the supporting beam and is detachably connected to the supporting beam by bolts. The first connecting concave block covers the top of the bottom beam and is detachably connected to the bottom beam by bolts. Both sides of the inner cavity bottom of the second connecting concave block are rotatably connected with first reinforcing support rib plates. Both sides of the inner cavity top of the first connecting concave block are rotatably connected with second reinforcing support rib plates. The two second reinforcing support rib plates are respectively located at the bottoms of the corresponding first reinforcing support rib plates, and one end of the first reinforcing support rib plate extends to the second reinforcing support rib plate and is detachably connected to the second reinforcing support rib plate by bolts. The tops of the two second reinforcing support rib plates are both installed with third connecting concave blocks by bolts, and each third connecting concave block is located at the bottom of the supporting beam and is detachably connected to the supporting beam by bolts. Two second hydraulic rods are rotatably connected to one side of the bottom beam through pin shafts, and the output ends of each second hydraulic rod extend to one side of the supporting beam and are rotatably connected to the supporting beam through pin shafts;

[0011] It can be seen that in the above technical solution, when the supporting beam is under force of lifting, it will drive the third connecting concave block and the first connecting concave block to displace downward. When the third connecting concave block and the first connecting concave block displace downward, they will squeeze the first reinforcing support rib plate and the second reinforcing support rib plate. Through the toughness of the first reinforcing support rib plate and the second reinforcing support rib plate themselves, it drives the supporting beam to displace upward, realizing the function of reducing the force received by the device. At the same time, when the device is in use, it starts through the first hydraulic rod and the second hydraulic rod, driving the supporting beam to displace upward. The traction of the output ends of the first hydraulic rod and the second hydraulic rod extending can form a triangular support function for the supporting beam, ensuring its stability during support.

[0012] The technical effects and advantages of the present utility model:

[0013] By setting the reinforcing support assembly, compared with the prior art, the overall design is simple and the structure is reasonable. Through the corresponding cooperation of each structure, the bottom beam is used as the support point, and the supporting beam is used for lifting. When the bottom beam displaces, it drives the supporting wheels to displace. The guide ring and the side baffle are used to guide and limit the displacement of the supporting wheels when they displace, ensuring the stability of the bottom beam and the supporting beam when moving on the gantry;

[0014] When the third connecting concave block and the second connecting concave block are displaced downward, they will squeeze the first reinforcing rib plate and the second reinforcing rib plate. Driven by the toughness of the first reinforcing rib plate and the second reinforcing rib plate themselves, the supporting beam is displaced upward, realizing the function of reducing the force received by the device. At the same time, when the device is in use, it is started through the first hydraulic rod and the second hydraulic rod, driving the supporting beam to displace upward. The traction extended from the output ends of the first hydraulic rod and the second hydraulic rod can form a triangular support function for the supporting beam, ensuring its stability during support.
