[0001] The utility model relates to the field of gantry machining centers, and more specifically, to a beam moving device of a gantry machining center. Background Art

[0002] A gantry machining center is 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 portal structure frame composed of double columns and a top beam. There is also a crossbeam in the middle of the double columns. It is particularly suitable for processing large workpieces and workpieces with complex shapes. There are fixed beam type (crossbeam is fixed, worktable moves / rotates), movable beam type (crossbeam moves up and down, worktable moves back and forth), movable column type (worktable is fixed, gantry moves), and overhead crane type (worktable is fixed, crossbeam moves).

[0003] However, the beam moving device of the gantry machining center in the prior art cannot automatically lubricate the beam moving device when in use, and the staff needs to manually lubricate the beam moving device, which is very inconvenient to use and affects the normal movement of the beam moving device. To address this problem, it is necessary for technicians in this field to develop a beam moving device for a gantry machining center. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a beam moving device for a gantry machining center. By setting a sliding part and an oil-immersed part, when the beam moving device is insufficiently lubricated and the sliding part is pulled, the friction between the sliding part and the top of the beam increases, causing the sliding part to contract through the connecting plate squeezing the spring, and finally the lubricating oil inside the oil-immersed part will lubricate the beam, so as to achieve the effect of automatically lubricating the beam moving device, thereby solving the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a crossbeam moving device of a gantry machining center, comprising a machining center body, the top of the machining center body is rotatably connected to a connecting rod, the outer wall of the connecting rod is rotatably connected to a control panel box, one side of the machining center body is slidably connected to a protective door, an observation window is fixedly installed on the outer wall of the machining center body, a workbench and a longitudinal beam are fixedly installed inside the machining center body, the top of the longitudinal beam is slidably connected to a crossbeam, the top of the crossbeam is slidably connected to a slide box, the outer wall of the slide box is slidably connected to a ram, the outer wall of the slide box is fixedly installed with a lubricating oil tank, and the top of the lubricating oil tank is threadedly connected to a sealing cover.

[0006] In a preferred embodiment, the bottom of the lubricating oil tank is connected to a stop valve, and the end of the valve stem of the stop valve is fixedly connected to a gear.

[0007] In a preferred embodiment, one end of the stop valve is connected to a hose, and one end of the hose away from the stop valve is connected to a sliding member, and the sliding member is provided on one side of the slide box.

[0008] In a preferred embodiment, the sliding member is slidably connected to the top of the beam, an oil-immersed member is fixedly installed inside the sliding member, and the oil-immersed member is slidably connected to the top of the beam.

[0012] Technical effects and advantages of this utility model:

[0013] 1. The utility model is provided with a sliding part and an oil-immersed part. When the crossbeam moving device is insufficiently lubricated and the sliding part is pulled, the friction between the sliding part and the top of the crossbeam increases, causing the sliding part to squeeze the spring through the connecting plate and contract. Finally, the lubricating oil inside the oil-immersed part will lubricate the crossbeam, thereby achieving the effect of automatically lubricating the crossbeam moving device. Manual lubrication is not required, which prevents the staff from failing to lubricate in time and affecting the service life of the crossbeam moving device of the gantry machining center.

[0014] 2. The utility model is provided with a rack and a spring. When the oil-immersed part completes lubrication of the crossbeam, the friction between the crossbeam and the sliding part is reduced, so that the spring can push the sliding part to reset through the connecting plate, and finally the rack drives the gear to rotate and reset, so that the stop valve is closed and re-sealed, and the discharge of lubricating oil into the sliding part is stopped, so as to achieve the effect of automatic recovery after lubrication is completed and wait for the next lubrication.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1: Refer to the attached instructions Figure 1-3 The utility model is a beam moving device for a gantry machining center, including a machining center body 1, see Figure 1 The top of the machining center body 1 is rotatably connected to a connecting rod 2, and the outer wall of the connecting rod 2 is rotatably connected to a control panel box 3. A protective door 4 is slidably connected to one side of the machining center body 1. An observation window 5 is fixedly installed on the outer wall of the machining center body 1. A workbench 6 and a longitudinal beam 7 are fixedly installed inside the machining center body 1. The top of the longitudinal beam 7 is slidably connected to a crossbeam 8. The top of the crossbeam 8 is slidably connected to a slide box 9. The outer wall of the slide box 9 is slidably connected to a ram 10. See Figure 3 , a lubricating oil tank 11 is fixedly mounted on the outer wall of the sliding box 9, and a sealing cover 12 is connected to the top of the lubricating oil tank 11 by a thread;

[0021] The bottom of the lubricating oil tank 11 is connected to a stop valve 13, the valve stem end of the stop valve 13 is fixedly connected to a gear 14, one end of the stop valve 13 is connected to a hose 15, and the end of the hose 15 away from the stop valve 13 is connected to a sliding member 16, which is arranged on one side of the slide box 9, and the slide 16 is slidably connected to the top of the beam 8. An oil immersion member 17 is fixedly installed inside the slide 16, and the oil immersion member 17 is slidably connected to the top of the beam 8, and a connecting plate 18 is fixedly connected to the top of the slide 16, and a rack 19 is fixedly connected to the outer wall of the connecting plate 18, and the rack 19 is meshed with the outer wall of the gear 14, and a spring 20 is fixedly installed on one side of the connecting plate 18, and a limiting member 21 is inserted into the inside of the spring 20, and the limiting member 21 is fixedly connected to one side of the slide box 9.

[0022] It should be noted that, when the staff controls the gantry machining center through the control panel box 3, the crossbeam 8 will slide on the top of the longitudinal beam 7 (the crossbeam 8 has the same structure as the slide box 9, which can automatically lubricate the longitudinal beam 7), and the slide box 9 will slide on the top of the crossbeam 8. The sliding of the slide box 9 will push the slide 16 to slide along the top of the crossbeam 8, or pull the slide 16 to slide along the top of the crossbeam 8 through the limiter 21, the spring 20, and the connecting plate 18. When the top of the crossbeam 8 is not lubricated enough and the slide 16 is pulled, the friction between the slide 16 and the top of the crossbeam 8 increases, causing the slide 16 to slide through the connecting plate 18. The plate 18 squeezes the spring 20 to contract, thereby causing the connecting plate 18 to drive the gear 14 to rotate through the rack 19, allowing the gear 14 to drive the stop valve 13 to open through the valve stem, allowing the lubricating oil inside the lubricating oil tank 11 to enter the inside of the hose 15 through the stop valve 13, allowing the hose 15 to discharge the lubricating oil into the inside of the sliding part 16 and immerse it in the inside of the oil-immersed part 17. Then, the lubricating oil inside the oil-immersed part 17 will lubricate the crossbeam 8, thereby achieving the effect of automatically lubricating the crossbeam moving device, without the need for manual lubrication by the staff, to prevent the staff from failing to lubricate in time and affecting the service life of the crossbeam moving device of the gantry machining center;

[0023] Furthermore, when the oil immersion member 17 has completed lubrication of the crossbeam 8, the slide box 9 continues to pull the slide 16 to slide along the top of the crossbeam 8 through the limit member 21, the spring 20, and the connecting plate 18, the slide 16 will slide to the part of the crossbeam 8 that has been lubricated. At this time, the friction between the lubricated crossbeam 8 and the slide 16 is reduced, so that the spring 20 can push the slide 16 to reset through the connecting plate 18, and then the relative position of the slide 16 and the slide box 9 is reset, and then the slide 16 drives the rack 19 to reset through the connecting plate 18, and the rack 19 drives the gear 14 to rotate and reset, so that the stop valve 13 is closed and re-sealed, and the lubricating oil is stopped from being discharged into the interior of the slide 16, so as to achieve the effect of automatic recovery after lubrication is completed and wait for the next lubrication.
