[0002] Gantry machining center refers to a machining center in which the axis of the spindle Z axis is set perpendicular to the worktable. The overall structure is a large-scale machining center with a double column and a top beam forming a gantry structure frame, and there is a crossbeam in the middle of the double column. It is especially suitable for machining large workpieces and workpieces with complex shapes.

[0003] When processing large workpieces, the milling head is driven by the top crossbeam of the gantry CNC center to process at different positions of the workpiece.

[0004] However, the beams of the existing gantry CNC centers are all integrated. When transporting and assembling the beams, it is difficult for workers to adjust the beams during installation because the beams are too heavy, which makes installation inconvenient and reduces work efficiency.

[0005] In addition, the existing crossbeams need a certain degree of rigidity to prevent deformation during use, and the weight of the crossbeams cannot be too heavy. The existing reinforcement structures are all integrated and too heavy. Utility Model Content

[0006] The utility model aims to provide a crossbeam structure of a gantry CNC machining center to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a beam structure of a gantry CNC machining center, including a beam body, characterized in that: a shell is located on one side of the beam body; a slide groove is provided on one side of the beam body, and the side of the beam body away from the slide groove is connected to the shell by a snap-fitting form, one side of the shell is connected to the side bolt through a thread, one end of the side bolt is connected to the reinforcement block through a thread, the top of the beam body is connected to the top bolt through a thread, one end of the top bolt is connected to the top of the reinforcement block through a thread, a top fixing plate is provided on one side of the reinforcement block, a bottom fixing plate is provided under the top fixing plate, and limit blocks are provided on both sides of the shell.

[0008] Preferably, a screw rod is provided inside the slide groove, and both ends of the screw rod are connected to the inner wall of the slide groove through a rotating shaft, the top of the beam body is connected to one end of the support column through a fastener, the end of the support column away from the beam body is connected to the telescopic column in an embedded form, and the end of the telescopic column away from the support column is connected to the limit block through a fastener.

[0009] Preferably, a bracket is provided on the inner side of the reinforcement block, and two ends of the bracket are connected to the inner wall of the reinforcement block by welding, and the bracket is in a cross form on the reinforcement block.

[0010] Preferably, the reinforcement block is provided with weight-reducing holes, the weight-reducing holes are distributed at equal intervals on the reinforcement block, and the reinforcement blocks are distributed at equal intervals inside the shell.

[0011] Preferably, a top side of the reinforcement block is connected to the top fixing plate by welding, and a bottom side of the reinforcement block is connected to the bottom fixing plate by welding.

[0012] Preferably, the top of the bottom fixing plate is connected to the column by welding, and one end of the column away from the bottom fixing plate is connected to the bottom of the top fixing plate by welding.

[0013] Preferably, the interior of the support column is connected to one end of the elastic member via a fastener, and the end of the elastic member away from the support column is connected to the end of the telescopic column away from the limit block via a fastener.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] First, the utility model can facilitate the installation of the beam body by providing a shell and a limit block. When the beam body needs to be installed, the beam body is moved to the top of the double columns for fixation, and then the reinforcement block and the shell are connected by side bolts, and the connected reinforcement block and shell are moved to one side of the beam body, and the limit block is pushed upward. The limit block moves upward to squeeze the elastic member through the telescopic column, and then pushes the shell. The shell moves until one end moves to the limit block on the other side, and then the beam body and the reinforcement block are fixed by the top bolts, and the installation of the beam body is completed, which prevents the beam body from being too heavy and making it difficult to install the beam body, and embodies the practicality of this device.

[0016] Second, the utility model can increase the rigidity of the beam body by arranging reinforcement blocks and columns. Inward grooves are opened on both sides of the reinforcement blocks, and a through hole is opened in the center of the reinforcement blocks. This reduces the weight while increasing the strength of the structure. The bracket is located in the groove of the reinforcement block to prevent the reinforcement block from being deformed when squeezed. The bracket forms a triangular structure in the form of an oblique angle. The bottom fixing plate and the top fixing block are inclined in opposite directions. The top fixing plate and the top fixing plate are connected to each other through the columns. The other ends of the top fixing plate and the bottom fixing plate are used to connect with another reinforcement block to increase the strength of the beam where there is no reinforcement block, and to support the downward force of the beam body. The reinforcement block is used to prevent the beam body from tilting and deforming to both sides, so as to achieve the goal of making the beam body rigid while reducing its weight.
