[0002] As a key piece of equipment in the machining field, the guide rail of the boring machine is the core component that ensures the accurate linear motion of the worktable, column and other parts. The fitting accuracy between the guide rail and the slide directly affects the dimensional accuracy and surface quality of the boring process. Continuous and uniform lubrication is an important guarantee for reducing friction and wear between the two, extending service life and maintaining motion stability. Therefore, lubricating the guide rail is of utmost importance.

[0003] However, commonly used lubrication methods have shortcomings. Traditional lubrication of boring machine guideways is mainly done manually, that is, the operator manually applies or adds lubricating oil to the guideway surface at regular intervals. This method takes a lot of time and consumes a lot of labor. Moreover, the lubrication time is judged manually, which can easily lead to problems of untimely lubrication due to operational negligence, thus affecting the normal use of the equipment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 - Figure 3 One embodiment of this utility model is an automatic lubrication device for a boring machine guide rail, including a support base 1 for supporting the overall device, a guide rail body 2 for providing guidance mounted on the upper surface of the support base 1, a slide 3 for driving the column 4 to move on the inner surface of the guide rail body 2, a column 4 mounted on the upper surface of the slide 3, an automatic lubrication mechanism for realizing automatic lubrication and ensuring smooth movement is provided inside the slide 3, and an indicator component 7 for easy observation of the oil level by personnel from the outside is provided on the front surface of the slide 3.

[0020] Reference Figure 2 - Figure 4 The automatic lubrication mechanism includes a positioning component 5, which includes a connecting seat 52. The connecting seat 52 is piston-connected to the inner wall of the slide 3. The connecting seat 52 moves laterally. A roller 55 is provided at the right end of the connecting seat 52. The center of the roller 55 is always in the connecting seat 52. The positioning component 5 also includes multiple sets of stops 51 that squeeze the roller 55 to drive the connecting seat 52 to move. The multiple sets of stops 51 are evenly distributed front and back and fixedly connected to the left and right ends of the inner surface of the guide rail body 2. The inner wall of the slide 3 is elastically connected to a slider 53 through an elastic element 54.

[0021] Reference Figure 1 , Figure 3 , Figure 5 The automatic lubrication mechanism also includes a lubrication component 6 for oiling and lubrication. The lubrication component 6 includes a one-way valve 61, which is existing technology and can be implemented by those skilled in the art. The one-way valve 61 allows only external lubricating oil to be added. The one-way valve 61 is disposed through the upper section of the front surface of the slide block 3. An oil reservoir 62 for storing lubricating oil is formed in the inner wall of the slide block 3. A drainage groove 63, L-shaped, is formed through the upper surface of the connecting seat 52. Initially, the drainage groove 63 and the oil reservoir 62 are not aligned. When the stop block 51 squeezes the roller shaft 55 and drives the connecting seat 52 to move toward the center of the slide block 3, it will gradually align with the oil storage cavity 62. The lubricating oil will be stored in the diversion groove 63 for lubrication. A sponge ring 64 is fixedly connected to the outer wall of the roller shaft 55. The sponge ring 64 can absorb the lubricating oil, and the sponge ring 64 is in contact with the inner surface of the guide rail body 2 to achieve lubrication. A positioning block 66 is fixedly connected to the right surface of the connecting seat 52. A positioning groove 65 is opened on the outer wall of the roller shaft 55. The positioning block 66 and the positioning groove 65 fit together.

[0022] Reference Figure 1 , Figure 3 , Figure 5 The right end of the drainage groove 63 is aligned with the sponge ring 64. The lubricating oil in the drainage groove 63 will flow to the sponge ring 64. The sponge ring 64 is set as an annular shape. The positioning groove 65 is also annular. The cross-section of the positioning groove 65 and the positioning block 66 are both "T-shaped", which can provide guidance for the roller 55. The right end of the roller 55 is in contact with the inner surface of the guide rail body 2. The slider 53 is slidably connected to the inner wall of the slide block 3. When the slider 53 slides toward the middle of the slide block 3, it will squeeze the elastic element 54 to generate a reaction force. The rear surface of the slide block 3 is fixedly connected to the front surface of the connecting seat 52.

[0023] Reference Figure 1 , Figure 2 , Figure 6 The indicator component 7 includes an observation tube 71, which is made of transparent material for easy observation. The observation tube 71 is connected through and fixed to the bottom of the front surface of the slide block 3. A float ball 72 is provided on the inner wall of the observation tube 71. The front surface of the observation tube 71 is marked with a scale. By observing the scale at the corresponding position of the float ball 72, it can be determined whether refueling is needed.

[0024] Working principle: When the slide 3 moves back and forth along the guide rail body 2, multiple sets of stops 51 at both ends of the inner surface of the guide rail body 2 will contact the roller 55. The stops 51 squeeze the roller 55, causing the connecting seat 52 to move laterally towards the middle of the slide 3. At this time, the slider 53 connected to the connecting seat 52 slides synchronously on the inner wall of the slide 3 and squeezes the elastic element 54 to generate a reaction force. During the movement of the connecting seat 52, the L-shaped drainage groove 63 on its surface gradually aligns with the oil storage cavity 62 on the inner wall of the slide 3. The lubricating oil in the oil storage cavity 62 flows through the drainage groove 63 to the annular sponge ring 64 on the outer wall of the roller 55. Since the sponge ring 64 keeps in contact with the inner surface of the guide rail body 2 and the slide 3 moves continuously, the sponge ring 64 will evenly spread the absorbed lubricating oil on the guide rail body 2 to achieve automatic lubrication.

[0025] When the slide block 3 moves to disengage from the stop block 51, the reaction force of the elastic element 54 pushes the slider 53 to reset, thereby driving the connecting seat 52 and the roller 55 back to their initial positions. The flow channel 63 is misaligned with the oil storage chamber 62, stopping the oil supply and avoiding excessive lubrication.

[0026] In addition, lubricating oil can be added to the oil reservoir 62 through the one-way valve 61. The one-way valve 61 can prevent the lubricating oil from flowing back. A float 72 is installed in the transparent observation tube 71. The float 72 will rise and fall with the change of oil volume in the oil reservoir 62. The operator can judge whether lubricating oil needs to be added according to the scale corresponding to the float 72.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
