Description

Technical Field

[0001] The utility model belongs to the technical field of linear rail lubrication, in particular to a linear rail for a vertical machining center machine tool. Background Art

[0002] The main function of a machining center's linear rails is to support the operation of the worktable and the movement of the three axes of the machining center. The linear rails consist of two parts: a slider and a rail. The slider contains balls or rollers, and the rails can be customized to any length. A modular design, the linear rails use the rolling friction of the balls or rollers to move the worktable. To ensure smooth sliding during use, the linear rails require lubrication. Insufficient lubrication of the linear rails can increase friction, affecting the efficiency and accuracy of the machine tool.

[0003] Currently, there are two main methods of lubrication for linear rails. One is manual lubrication, which requires regular checks and re-lubrication at regular intervals or repetitions. The other is automatic lubrication, which automatically lubricates the equipment according to preset parameters during operation, either periodically or continuously. Automatic lubrication eliminates the need for manual operation, and the lubrication cycle and frequency can be automatically adjusted, resulting in stable and reliable lubrication. However, it is important to note that automatic lubrication requires parameter setup and adjustment, and the equipment has specific requirements for lubricant quality and refueling volume.

[0004] Problems with existing technologies:

[0005] For the above two methods, the slider itself does not have the effect of storing oil, so it needs to be frequently refueled or rely on an external oil pipe for oil supply. In this way, the external oil pipe is prone to bending or wear during the movement of the slider, thereby causing leakage of lubricating oil. Secondly, the output amount of lubricating oil during the lubrication of the slider cannot be controlled, thereby increasing the loss of lubricating oil. Utility Model Content

[0006] The purpose of the utility model is to provide a vertical machining center machine tool linear rail that can solve the above technical problems.

[0007] The technical solutions adopted by this utility model are as follows:

[0008] The utility model provides a vertical machining center machine tool linear rail, comprising a slide rail and a slider assembly connected thereto, the slider assembly comprising a sliding support block and two sealed end plates, two groups of ball sliders being slidably arranged on the slide rail, a lubrication mechanism for lubrication being provided between each group of the ball sliders, the sliding support block being connected to a support connecting plate via a hexagon socket screw, a support connecting plate being welded between each group of the ball sliders, and the two sealed end plates connecting the sliding support block and the ball sliders via hexagon socket screws;

[0009] The lubrication mechanism includes two lubrication wheels and a telescopic storage bag that fit in the upper and lower slide grooves formed on the side of the slide rail. A barrier frame for wrapping the extended storage bag is provided between each group of ball sliders. The barrier frame is fixed on the fastening plate. Two hollow rotating tubes are rotatably provided on the barrier frame. The lubrication wheels are interconnected with the hollow rotating tubes. The telescopic storage bag is provided with an oil pipeline that is interconnected. The oil pipeline is provided with two branch pipes, and the two branch pipes are respectively sleeved in the hollow rotating tubes.

[0010] The main sleeve of the oil pipeline is arranged in the clamping hole formed on the clamping hole plate, the inner side surface of the enclosure frame is fixedly connected to the clamping hole plate, and the clamping hole on the clamping hole plate is correspondingly provided with an adjusting screw, and the adjusting screw is matched with the thread of the fastening plate.

[0011] The above-mentioned vertical machining center machine tool linear rail is adopted. By rotating the adjusting screw, the adjusting screw is squeezed against the main pipe of the oil delivery pipe on the card hole plate, thereby reducing the output. In this way, the amount of oil in the lubricating wheel can be controlled, and the lubricating oil in the lubricating wheel is immersed in the lubricating cotton. Then, when the slider assembly slides along the slide groove on the slide rail, the lubricating cotton is rotated to fit the upper and lower surfaces of the slide groove and covered with lubricating oil. In this way, when the ball slider slides, the ball contacts and adheres to the lubricating oil on the upper and lower surfaces of the slide groove, thereby performing lubrication treatment.

[0012] Preferably, the supporting connecting plate is provided with a plug-in plate through a formed plug-in hole, and the two sealing end plates are detachably connected to a fastening plate through hexagon socket screws, and the plug-in plate is fixed on the fastening plate.

[0013] Preferably, a self-sealing hollow column made of rubber is glued to the fastening plate, and the self-sealing hollow column is glued to the telescopic storage bag.

[0014] Preferably, the lubricating wheel is made of rubber and has a plurality of oil outlet holes extending inside and outside the circumferential surface. An inner support plate is provided on the inner circumferential surface of the lubricating wheel, and the inner support plate is connected to the free end of the branch pipe of the oil pipeline through a formed circular hole.

[0015] Preferably, lubricating cotton is glued to the outer peripheral surface of the lubricating wheel, and the lubricating cotton is squeezed and attached to the upper and lower surfaces of the sliding groove formed on the slide rail.

[0016] The beneficial effects are:

[0017] The utility model uses the lubrication mechanism on the slider assembly to enable the telescopic storage bag on the lubrication mechanism to supply lubricating oil to the two lubricating wheels by relying on the telescopic storage bag, and at the same time relies on the adjustment screw to squeeze the main pipe of the oil pipeline, thereby independently adjusting the output of the oil pipeline, reducing the refueling frequency, and further reducing the loss of lubricating oil.

[0025] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0026] like Figure 1-5 As shown, a vertical machining center machine tool linear rail includes a slide rail 1 and a slider assembly connected thereto. The slider assembly includes a sliding support block 2 and two sealed end plates 3. Two groups of ball sliders 4 are slidably arranged on the slide rail 1. A lubrication mechanism 5 for lubrication is provided between each group of ball sliders 4. The sliding support block 2 is connected to a support connecting plate 41 via an inner hexagonal screw. A support connecting plate 41 is welded between each group of ball sliders 4. The two sealed end plates 3 connect the sliding support block 2 and the ball slider 4 via inner hexagonal screws.

[0027] The lubrication mechanism 5 includes two lubrication wheels 510 and a telescopic storage bag 508 that fit in the upper and lower slide grooves formed on the side of the slide rail 1. A barrier frame 506 for wrapping the extended storage bag is provided between each group of ball sliders 4. The barrier frame 506 is fixed on the fastening plate 501. Two hollow rotating tubes 509 are rotatably provided on the barrier frame 506. The lubrication wheels 510 are interconnected with the hollow rotating tubes 509. The telescopic storage bag 508 is provided with an oil delivery pipe 507 that is interconnected. The oil delivery pipe 507 is provided with two branch pipes, and the two branch pipes are respectively sleeved in the hollow rotating tube 509.

[0028] The main sleeve of the oil delivery pipe 507 is installed in the card hole formed on the card hole plate 505, and the inner surface of the enclosure frame 506 is fixedly connected to the card hole plate 505. The card hole on the card hole plate 505 is correspondingly provided with an adjusting screw 504, and the adjusting screw 504 is threadedly matched with the fastening plate 501. With this arrangement, the enclosure frame 506 can be used to limit the expansion space of the telescopic storage bag 508, thereby avoiding excessive expansion of the telescopic storage bag 508 and causing friction on the slide rail 1.

[0029] As an optional embodiment, the support connecting plate 41 is provided with a plug-in plate 503 through a formed plug-in hole, and the two sealing end plates 3 are detachably connected to the fastening plate 501 through hexagon socket screws. The plug-in plate 503 is fixed on the fastening plate 501. Such a configuration allows the lubrication mechanism 5 to be installed by utilizing the plug-in relationship between the plug-in plate 503 and the support connecting plate 41, so that the lubrication mechanism 5 can be easily installed and then fastened.

[0030] Refer to the attached Figure 3 and attached Figure 4 A self-sealing hollow column 502 made of rubber is glued to the fastening plate 501, and the self-sealing hollow column 502 is glued to the telescopic storage bag 508. With this arrangement, when replenishing lubricating oil in the telescopic storage bag 508, a syringe can be used to puncture the self-sealing hollow column 502 into the telescopic storage bag 508 for replenishment.

[0031] Refer to the attached Figure 5 The lubricating wheel 510 is made of rubber and has a plurality of oil outlet holes running through it on its circumferential surface. An inner support plate 510a is provided on the inner circumferential surface of the lubricating wheel 510. The inner support plate 510a is connected to the free end of the branch pipe of the oil pipe 507 through a formed circular hole. With this arrangement, the lubricating oil in the telescopic storage bag 508 can be transported to the lubricating wheel 510 through the branch pipe of the oil pipe 507, and the oil is evenly immersed in the lubricating cotton 510b by the rotation of the lubricating wheel 510.

[0032] Furthermore, lubricating cotton 510b is glued to the outer peripheral surface of the lubricating wheel 510, and the lubricating cotton 510b is squeezed and attached to the upper and lower surfaces of the slide groove formed on the slide rail 1. When the lubricating cotton 510b rotates, it can be squeezed with the upper and lower surfaces of the slide groove, thereby ensuring that the lubricating oil adsorbed in the lubricating cotton 510b is squeezed out and attached to the upper and lower surfaces of the slide groove, thereby improving the coverage effect of the lubricating oil.

[0033] With the above structure, by rotating the adjusting screw 504, the adjusting screw 504 squeezes the main pipe of the oil delivery pipe 507 on the card hole plate 505, thereby reducing the output. In this way, the amount of oil in the lubricating wheel 510 can be controlled, so that the lubricating oil in the lubricating wheel 510 is immersed in the lubricating cotton 510b, and then when the slider assembly slides along the slide groove on the slide rail 1, the lubricating cotton 510b is rotated to fit the upper and lower surfaces of the slide groove and covered with lubricating oil. In this way, when the ball slider 4 slides, the balls contact and adhere to the lubricating oil on the upper and lower surfaces of the slide groove, thereby performing lubrication.

[0034] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
