Description

Technical Field

[0001] The utility model relates to the technical field of gantry machining, in particular to a lubrication device for a gantry machining center. Background Technique

[0002] A gantry machining center refers to a machining center with a spindle axis perpendicular to the workbench. Its overall structure is a gantry frame, composed of two columns and a top beam, and there is also a crossbeam in the middle. It is especially suitable for machining large workpieces and workpieces with complex shapes. A slider is a die component that can slide perpendicular to the mold opening and closing direction or at a certain angle to the mold opening and closing direction during the mold opening action of the mold. The slider slides on the slide rail, and generally lubricating fluid is added to achieve the lubrication purpose to ensure the normal operation of the guide rail and the slider, improve the friction state of the friction pair to reduce the friction resistance and slow down the wear. In addition, the lubricating fluid also has functions such as rust prevention, vibration reduction, sealing, and power transmission. Making full use of modern lubrication technology can significantly improve the service performance and life of the machine and reduce energy consumption. For the lubrication of the slider of the gantry machining center, situations such as too much or too little lubricating oil being applied often occur during use, wasting a lot of lubricating oil, and a large amount of dust will adhere during use, resulting in the machine breaking down very early. Moreover, some existing lubrication devices for the slider of the gantry machining center often have a simple structure and are difficult to clean the slider, making it impossible to obtain a good lubrication effect. Therefore, we propose a lubrication device for a gantry machining center. Content of the Utility Model

[0003] The utility model provides a lubrication device for a gantry machining center, which solves the problems raised in the above background technique.

An infusion channel connected to the transmission channels is opened inside the slide rail. At the same time, moving blocks for controlling the liquid outlet are movably installed on both sides of the slide rail.

[0011] The utility model has the following beneficial effects:

[0012] 1. For the lubrication device for a gantry machining center, through the drive of the moving block, the lubricating liquid in the transmission channel can be discharged from the liquid outlet to add to the inner side wall of the slider. At the same time, the lubricating liquid in the transmission channel is added to the coating roller. Under the rotation of the coating roller, the inner top of the slider can be coated. Thus, when the slider slides, the lubricating liquid can be added, making the addition of the lubricating liquid more convenient.

[0013] 2. For the lubrication device for a gantry machining center, through the movement of the moving block, the hydraulic film can be driven to move.

[0014] 3. For the lubrication device for a gantry machining center, through the cooperation of the valve, the first plugging ball, and the second plugging ball, the lubricating liquid in the transmission channel can be discharged smoothly, then added between the slider and the slide rail.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 6, a lubrication device for a gantry machining center, including a slide rail 1. A lubrication groove is opened at the top of the slide rail 1, and lubricating fluid can be applied to the outer surface of the application roller 2 through the lubrication groove. The application roller 2 is connected to the lubrication groove by a pin, enabling the application roller 2 to rotate at a fixed position on the slide rail 1. Under the rotation of the application roller 2, the lubricating fluid can be smoothly applied to the inner top of the slider. Moreover, liquid outlets are opened on both sides of the slide rail 1, so that the lubricating fluid can be smoothly added between the slide rail 1 and the inner side wall of the slider. Additionally, a plurality of transmission channels 5 corresponding to the liquid outlets and the lubrication groove are opened inside the slide rail 1, and the transmission channels 5 are connected to the liquid outlets and the lubrication groove, so that the lubricating fluid in the transmission channels 5 can smoothly enter the liquid outlets and the lubrication groove. An infusion channel 4 connected to the transmission channels 5 is opened inside the slide rail 1, and the lubricating fluid in the infusion channel 4 can enter the transmission channels 5. Meanwhile, moving blocks 3 for controlling liquid outflow are movably installed on both sides of the slide rail 1. When the slider moves to the position of the moving block 3, it then pushes the moving block 3 to move into the inside of the slide rail 1, and at this time, the liquid outlets and the lubrication groove are opened.

[0024] Please refer to Figures 1 to 4 , one end of the moving block 3 is circular, so that the slider can more smoothly push the moving block 3 to move. And the other end of the moving block 3 extends into the inside of the slide rail 1 and is fixed with a hydraulic film 8. Under the push of the moving block 3, the middle of the hydraulic film 8 can move. The hydraulic film 8 is made of a deformable material, and the outer ring of the hydraulic film 8 is fixedly connected to the slide rail 1. Under the movement of the middle of the hydraulic film 8, the hydraulic film 8 deforms, thereby changing the pressure inside the transmission channel 5.

[0025] Please refer to Figures 1 to 4 , a first fixing frame 6 is fixedly connected inside the slide rail 1. The first fixing frame 6 is movably connected to the moving block 3, and the first fixing frame 6 can limit the movement track of the moving block 3. And a first spring 7 is fixedly connected to the moving block 3. One end of the first spring 7 is fixed to the first fixing frame 6. Under the action of the elastic force of the first spring 7, the moving block 3 can smoothly return to its original position. At the same time, the hydraulic film 8 is made of rubber material, and one side of the hydraulic film 8 is connected to the transmission channel 5, so that the pressure inside the transmission channel 5 can be changed through the deformation of the hydraulic film 8.

[0026] Please refer to Figures 1 to 4 , a cross-shaped second fixing frame 10 is fixedly connected inside the liquid outlet, so that the lubricating fluid can smoothly flow out through the second fixing frame 10. The end of the liquid outlet communicating with the outside gradually expands outward. When the second fixing frame 10 moves outward, the valve 9 can be opened, so that the lubricating fluid can smoothly drain. And a valve 9 is movably connected to the middle of the second fixing frame 10, and the second fixing frame 10 can limit the movement track of the valve 9.

[0027] Please refer to Figures 1 to 4 , a second spring 11 is sleeved on the valve 9. One end of the second spring 11 is fixed on the valve 9, and the other end of the second spring 11 is fixed on the second fixing bracket 10. Under the action of the elastic force of the second spring 11, the valve 9 can smoothly return to its original position, thereby closing the liquid outlet.

[0028] Please refer to Figures 1 to 5 , a first sealing plate 12 and a braking plate 14 with a through hole are fixedly connected to the bottom end of the conveying channel 5, so that the lubricating liquid can smoothly pass through the braking plate 14. A first plugging ball 13 is movably connected between the first sealing plate 12 and the braking plate 14. When the moving block 3 moves into the slide rail 1, the first plugging ball 13 closes the first sealing plate 12. When the moving block 3 resets, the first plugging ball 13 opens, and the first plugging ball 13 can close the first sealing plate 12.

[0029] Please refer to Figures 1 to 6 , a second sealing plate 15 is fixedly connected to the top end of the conveying channel 5. A second plugging ball 16 is movably connected between the second sealing plate 15 and the slide rail 1. When the moving block 3 moves into the slide rail 1, the second plugging ball 16 opens. When the moving block 3 resets, the second plugging ball 16 closes the second sealing plate 15, and the second plugging ball 16 can close the second sealing plate 15.

[0030] In summary, for the lubrication device used in the gantry machining center, during use, the slider on the slide rail 1 slides, and then pushes the moving block 3 to move into the slide rail 1. Under the push of the moving block 3, the hydraulic film 8 moves. Under the push of the hydraulic film 8, the pressure in the conveying channel 5 becomes larger, and then pushes the valve 9 to move outward, so that the lubricating liquid can flow out to lubricate the inner side wall of the slider, and pushes the second plugging ball 16 to open upward, so that the lubricating liquid can flow into the lubricating groove and contact the outer side of the coating roller 2. When the slider rotates, the coating roller 2 can rotate, thereby coating the inner top of the slider. When the slider moves away, under the action of the elastic force of the first spring 7, the hydraulic film 8 moves back, the pressure in the conveying channel 5 becomes smaller, and then the first plugging ball 13 opens, so that the lubricating liquid in the liquid delivery channel 4 can timely fill the conveying channel 5.
