Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled machine tools, in particular to a numerically controlled gantry crossbeam bracket. Background Art

[0002] A CNC machine tool is an automated machine tool equipped with a program control system that can logically process programs specified by control codes or other symbolic instructions, decode them, represent them in coded numbers, and input them into the CNC device through information carriers. The gantry beam is used in machine tools with a portal frame and a horizontal long bed, and the machining surface is processed by moving the gantry beam and controlling the movement of the milling cutter.

[0003] The gantry beam itself is heavy. When installing it, it is usually lifted up by a lifting equipment. Most gantry beams have hanging holes for connecting with the lifting hooks of the lifting equipment or hanging rods for connecting with the hooks are fixed on the surface of the gantry beam. However, after the lifting equipment places the beam in the specified position, it is difficult to remove the hook quickly, and manual labor is required to reach the hook for disassembly, and the hook cannot be detached from the beam by controlling the lifting equipment.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The CNC gantry crossbeam support comprises two mounting seats and a crossbeam rod fixedly mounted on the upper ends of the two mounting seats, a slide rail is fixedly mounted on the upper end of the crossbeam rod, a mounting frame is slidably mounted on the upper end of the slide rail, the crossbeam rod is hollow, through-mouth grooves are respectively opened on both sides of the upper end of the crossbeam rod, and a hanging assembly for hook connection is respectively arranged inside the two through-mouth grooves;

[0007] The hanging component includes a rotating shaft and two sliding blocks symmetrically slidably arranged on the inner wall of the through-mouth groove, the two ends of the rotating shaft are respectively rotatably connected to the two sliding blocks, a hanging rod is fixedly arranged at the lower end of the rotating shaft, and the hanging rod is located inside the crossbeam, and the two sliding blocks are connected to the inner wall of the through-mouth groove via elastic ropes on the sides away from the hanging rod, and an inclined rod in contact with the upper end surface of the crossbeam is fixedly arranged on the side of the rotating shaft away from the hanging rod.

[0008] As a further description of the above technical solution:

[0009] A rotating shaft is rotatably provided through the middle of the hanging rod, a torsion spring is sleeved in the middle of the rotating shaft, a pressure plate matched with the inner top surface of the crossbeam is provided at one end of the rotating shaft, and a stopper is provided at the other end of the rotating shaft to prevent the hook from detaching from the hanging rod.

[0010] As a further description of the above technical solution:

[0011] The hanging rod is fixedly connected to the rotating shaft through a bolt, and the upper end of the bolt passes through the rotating shaft and is threadedly connected with a nut.

[0012] As a further description of the above technical solution:

[0013] The lower end surface of the rotating shaft is provided with a groove matched with the hanging rod.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0015] In the utility model, a rotating shaft, a slider, an elastic rope and a hanging rod are provided, and the hook sleeve is hung on the outside of the hanging rod so that the crossbeam rod is lifted. When the hook needs to be removed, the crossbeam rod is placed on the mounting seat. As the hook is released and moves downward, the hook releases the lifting force on the hanging rod. Under the action of the elastic rope, the slider is pulled to move, and then the inclined rod is squeezed to make the rotating shaft flip, driving the hanging rod to flip downward, so that the hanging rod is separated from the downwardly flipped hanging rod during the downward movement of the hanging rod, and the whole process does not require manual removal of the hook;

[0016] In the utility model, a rotating shaft, a pressure plate and a stopper are provided, so that when the hanging rod is lifted by the hook, the stopper is deflected so that the two ends of the stopper protrude outside the hanging rod, thereby achieving the effect of blocking the hook and preventing the hook from being separated from the hanging rod. When the hanging rod is separated from the hook, the pressure plate and the top surface of the inner side of the crossbeam are squeezed and contacted to cause deflection during the downward flipping of the hanging rod, thereby causing the rotating shaft to deflect and drive the stopper to deflect, so that the two ends of the stopper do not protrude outside the hanging rod, and then the hook can slide downward along the hanging rod and separate from the hanging rod.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] like Figure 1-3 As shown, the CNC gantry crossbeam support comprises two mounting seats 1 and a crossbeam rod 2 fixedly mounted on the upper ends of the two mounting seats 1, a slide rail 3 is fixedly mounted on the upper end of the crossbeam rod 2, a mounting frame 4 is slidably mounted on the upper end of the slide rail 3, and the mounting frame 4 is used to install the operating equipment. The crossbeam rod 2 is hollow, and through-mouth grooves 5 are respectively opened on both sides of the upper end of the crossbeam rod 2, and the two through-mouth grooves 5 are respectively provided with hanging components for hook connection;

[0024] The hanging component includes a rotating shaft 8 and two sliding blocks 7 symmetrically slidably arranged on the inner wall of the through-mouth groove 5, the two ends of the rotating shaft 8 are rotatably connected to the two sliding blocks 7, a hanging rod 10 is fixedly arranged at the lower end of the rotating shaft 8, the hanging rod 10 is located inside the crossbeam 2, and the two sliding blocks 7 are connected to the inner wall of the through-mouth groove 5 by elastic ropes 9 on the side away from the hanging rod 10, and an inclined rod 6 in contact with the upper end surface of the crossbeam 2 is fixedly arranged on the side of the rotating shaft 8 away from the hanging rod 10. During use, when it is necessary to remove the hook, the staff releases the hook to move downward by operating the lifting equipment to release the lifting force on the hanging rod 10. At this time, under the resetting action of the elastic rope 9, the sliding block 7 is pulled to drive the rotating shaft 8 to move. During the movement of the rotating shaft 8, the inclined rod 6 is squeezed against the crossbeam 2, thereby causing the rotating shaft 8 to deflect, causing the hanging rod 10 to flip downward, and then the hook will automatically disengage from the hanging rod 10 when it moves downward.

[0025] Furthermore, the hanging rod 10 is fixedly connected to the rotating shaft 8 by means of a bolt 13 , the upper end of the bolt 13 passes through the rotating shaft 8 and is threadedly connected with a nut 14 , so that the staff can conveniently connect and fix the hanging rod 10 to the rotating shaft 8 .

[0026] Furthermore, a groove 15 matching with the hanging rod 10 is formed on the lower end surface of the rotating shaft 8, which effectively ensures the stability of the connection between the rotating shaft 8 and the hanging rod 10 and facilitates and quickly aligns the threaded holes of the rotating shaft 8 and the hanging rod 10.

[0027] Embodiment 2:

[0028] like Figure 1-3As shown, a rotating shaft is provided through the middle of the hanging rod 10, a torsion spring is sleeved in the middle of the rotating shaft, a pressure plate 12 is provided at one end of the rotating shaft and matches with the inner top surface of the crossbeam 2, and a stopper 11 is provided at the other end of the rotating shaft to prevent the hook from detaching from the hanging rod 10. When the two end surfaces of the stopper 11 protrude outside the hanging rod 10, it can effectively prevent the hook from sliding off from one end of the hanging rod 10. The deflection of the stopper 11 will make the two end surfaces not protrude outside the hanging rod 10, thereby allowing the hook to slide off from the hanging rod 10.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
