Technical Field

[0001] The utility model relates to the technical field of machine tool crossbeams, in particular to an anti-deformation mechanism for a crossbeam of a numerically controlled gantry machine tool. Background Art

[0002] CNC gantry machine tools are large CNC machine tools that combine the structure of gantry machine tools with CNC technology and are used to process large, heavy and complex workpieces. Since the milling machines, boring machines, lathes and other machine tools are relatively large in size, beams are needed as load-bearing parts to install other heavier guide rails, spindles and other components.

[0003] According to the Chinese patent with announcement number: CN216371041U, a deformation-resistant concealed machine tool beam structure includes an outer beam frame and an inner beam extending in the left and right transverse directions, a first cavity is formed inside the outer beam frame, an annular rib plate is arranged in the first cavity, the inner edge of the annular rib plate surrounds a center hole and the outer edge is fixedly connected to the outer beam frame, the annular rib plates are arranged in the left and right directions, the inner beam is located in the first cavity and is erected on the annular rib plate through the center hole, the inner beam is fixedly connected to the annular rib plate or the outer beam frame, and the length of the inner beam is more than half of the length of the outer beam.

[0004] In the above scheme, the guide rail is usually fixed on the front side of the outer beam frame, which leads to the following disadvantages: after long-term operation, the guide rail is prone to aging and wear due to long-term use. At this time, the aged and worn guide rail needs to be replaced, and the guide rail is directly fixed on the beam, which reduces the convenience of replacing the guide rail. Utility Model Content

[0005] The utility model aims to provide a crossbeam anti-deformation mechanism for a numerically controlled gantry machine tool, so as to solve the problem that the guide rail is directly fixed on the crossbeam, which reduces the convenience of replacing the guide rail.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a CNC gantry machine tool beam anti-deformation mechanism, including a machine tool body, the machine tool body is arranged below the erection beam, resistance plates are fixed on both sides of the interior of the erection beam, one side of the resistance plate is fixed to the inner top surface of the erection beam, an installation folding plate is slidably arranged inside the erection beam, two sliding plates are slidably arranged below the installation folding plate, a plurality of sliding grooves are opened on the top surface of the sliding plate, a sliding rod is fixed on one side of the interior of the sliding groove, a plurality of connecting plates are fixed on the bottom surface of the installation folding plate, and the sliding rod and the connecting plate are slidably inserted.

[0007] Preferably, a fixing ring is fixed to the top surface of the mounting folding plate, a bearing is fixed inside the fixing ring, a threaded tube is fixed to the inner wall surface of the inner ring of the bearing, a threaded column is connected to the internal thread of the threaded tube, and the top end of the threaded column is fixed to the inner top surface of the mounting beam.

[0008] Preferably, two stabilizing rods are fixed to the inner top surface of the erection crossbeam, and stabilizing arc plates are fixed to both sides of the installation folding plate, respectively, and the stabilizing arc plates and the stabilizing rods are slidably arranged.

[0009] Preferably, thread grooves are respectively opened on both sides of the machine tool body, and through holes are respectively opened on both sides of the mounting crossbeam. Fixing bolts are rotatably inserted inside the through holes, and one end of the fixing bolts is threadedly connected to the thread groove.

[0010] Preferably, storage grooves are respectively provided on both sides of the erection beam, and a limit plate is detachably provided inside the storage groove. A positioning hole is provided on one side of the limit plate, and the positioning hole is rotatably inserted with a fixing bolt.

[0011] Preferably, universal wheels are fixed respectively at the four corners of the bottom surface of the machine tool body.

[0012] Compared with the prior art, a CNC gantry machine tool crossbeam anti-deformation mechanism using the above technical solution has the following beneficial effects:

[0013] 1. When installing the guide rail on the machine tool body, the guide rail will be installed with the installation beam as support. Since there are two resistance plates fixed inside the installation beam, the weight that the installation beam can bear is increased to prevent the installation beam from being deformed. Before installing the guide rail, the staff will first apply a force to the two sliding plates to move away from each other, that is, to push the two sliding plates away from each other, and during the sliding process, the sliding rod will be driven to slide in the connecting plate, so that the opening below the installation folding plate remains unobstructed, which is convenient for the staff to lay and install the guide rail inside the installation folding plate. After moving the guide rail to the inside of the installation folding plate, the staff will push the two sliding plates closer to each other again and intercept them under the guide rail to prevent the guide rail from falling out of the inside of the installation folding plate. The staff can control the loading and unloading of the guide rail by controlling the sliding of the sliding plate, which increases the convenience when loading and unloading the guide rail.

[0014] Second, when rotating the threaded tube, the staff can use the threaded connection between the threaded tube and the threaded column to control the installation folding plate to move up and down inside the erection beam, so as to adjust the height of the guide rail on the top surface of the machine tool body. When the installation folding plate moves up and down, the stabilizing arc plate will slide up and down synchronously on the surface of the stabilizing rod, so as to increase the stability of the installation folding plate when it moves up and down;

[0015] 3. When the staff installs the erection beam on the machine tool body, the staff will first lift the erection beam and move it so that the penetration hole moves to the position corresponding to the thread groove. Then the staff will place the limit plate into the storage groove, and finally pass the fixing bolt through the positioning hole and the penetration hole and screw it into the thread groove to fix the position of the erection beam on the machine tool body. The use of the limit plate increases the pressure on the erection beam and increases the firmness of the erection beam after installation. BRIEF DESCRIPTION OF THE DRAWINGS

Since there are two resistance plates 3 fixed inside the mounting crossbeam 2, the weight that the mounting crossbeam 2 can bear is increased to prevent the mounting crossbeam 2 from being deformed. Before installing the guide rail, the staff will first apply a force to the two sliding plates 5 to move away from each other, that is, to push the two sliding plates 5 away from each other, and during the sliding process, the sliding rod 7 will be driven to slide in the connecting plate 8, so that the opening below the mounting folding plate 4 remains unobstructed, which is convenient for the staff to lay and install the guide rail inside the mounting folding plate 4. After the guide rail is moved to the inside of the mounting folding plate 4, the staff will push the two sliding plates 5 closer to each other again and intercept them under the guide rail to prevent the guide rail from falling out of the inside of the mounting folding plate 4. The staff can control the loading and unloading of the guide rail by controlling the sliding of the sliding plate 5, which increases the convenience when loading and unloading the guide rail.

When the installation folding plate 4 moves up and down, the stabilizing arc plate 14 will synchronously slide up and down on the surface of the stabilizing rod 13, so as to increase the stability of the installation folding plate 4 when moving up and down.

[0026] like Figure 2 As shown, thread grooves 15 are respectively provided on both sides of the machine tool body 1, and through holes 16 are respectively provided on both sides of the mounting crossbeam 2.
