Description

Technical Field

[0001] This utility model relates to the field of guide rail maintenance mechanisms, and more particularly to a guide rail lubrication mechanism for a flat cutting machine. Background Technology

[0002] In machining, guideways are used very frequently. If proper maintenance is neglected, their lifespan will be very short. Guideway lubrication is a key measure to reduce friction, wear, and heat generation in mechanical systems. By forming a lubricating film on the guideway contact surface, it reduces motion resistance, improves motion accuracy, and extends equipment life. It also dissipates heat, prevents rust, and prevents contaminants from entering, making it suitable for high-precision applications such as machine tools and automated equipment.

[0003] In the existing technology, if the guide rail lacks or is missing a lubricating film, workers usually use manual operation, that is, to lubricate the guide rail by manually dripping or applying lubricating oil, or to directly add lubricating grease to the slide rail to achieve the purpose of lubricating the guide rail.

[0004] Regarding the aforementioned technologies, the inventors believe that during manual lubrication, in order to ensure personal safety, the ongoing work on the guide rail needs to be stopped. This delays the completion time of the entire operation and reduces work efficiency, leaving room for improvement. Utility Model Content

[0005] To reduce the inefficiency of existing manual lubrication guide rails, this invention provides a guide rail lubrication mechanism for a flat cutting machine.

[0006] The present invention provides a guide rail lubrication mechanism for a flat cutting machine, which adopts the following technical solution:

[0007] A guide rail lubrication mechanism for a planar cutting machine includes an oil tank installed on the planar cutting machine and moving with the planar cutting machine, an oil outlet on the oil tank, oil nozzles on the oil tank facing each surface of the guide rail, the oil outlet and the oil nozzles being interconnected, and an opening and closing assembly on the oil tank that opens the oil nozzles as the machine moves and closes the oil nozzles when the machine stops moving.

[0008] By adopting the above technical solution, the guide rail lubrication mechanism is automated by installing an oil tank that moves with the flat cutting machine and having an oil nozzle that opens as the machine moves, thereby improving the working efficiency and portability of the guide rail lubrication mechanism.

[0009] Optionally, the opening and closing assembly includes a gravity ball, a sliding track mounted on the flat cutting machine and parallel to the guide rail, and a connecting bracket. The gravity ball is located inside the oil tank and at the oil outlet, and seals the oil outlet. The connecting bracket is located inside the oil tank, with one end fixedly connected to the gravity ball and the other end extending through the oil tank to the outside. The end of the connecting bracket extending outside the oil tank abuts against the sliding track, and the sliding track has a contact surface that abuts against the connecting bracket. The contact surface is provided with a series of uneven surfaces.

[0010] By adopting the above technical solution, which includes a sliding rail, a connecting bracket, and a gravity ball, the force generated by the up-and-down movement during the movement is transmitted to the gravity ball through the connecting bracket to control the opening or closing of the oil outlet. This achieves automation of the guide rail lubrication mechanism and improves its working efficiency and portability.

[0011] Optionally, the oil tank is provided with an arc-shaped groove, the arc-shaped groove and the oil outlet are coaxially arranged, and the gravity ball is partially embedded in the arc-shaped groove and fits against each other.

[0012] By adopting the above technical solution, and by providing an arc-shaped groove on the oil tank and coaxially arranging the arc-shaped groove and the oil outlet, the gravity ball is partially embedded in the arc-shaped groove and fits against each other. When the gravity ball is lifted, the oil outlet opens, and when the gravity ball is lowered, the oil outlet closes. This realizes the automation of the guide rail lubrication mechanism by opening the oil outlet as the guide rail lubrication device moves and closing the oil outlet when it stops moving, thereby improving the portability of the guide rail lubrication mechanism.

[0013] Optionally, the sidewall of the arc-shaped groove is provided with a rubber pad that partially conforms to the gravity ball.

[0014] By adopting the above technical solution, a rubber pad is provided on the side wall of the arc-shaped groove to partially fit the gravity ball, so that the gravity ball can be completely sealed when it fits with the arc-shaped groove, thereby avoiding oil leakage and improving the stability of the guide rail lubrication mechanism.

[0015] Optionally, the gravity ball has a spike on the side near the arc-shaped groove, and when the gravity ball and the arc-shaped groove are in contact, the spike is embedded in the oil outlet.

[0016] By adopting the above technical solution, and by providing spikes on the side of the gravity ball near the arc-shaped groove, the oil outlet can be cleared by the spikes during the undulation of the gravity ball, so as to prevent the oil stains from accumulating and solidifying and causing blockage, thereby improving the stability of the guide rail lubrication mechanism.

[0017] Optionally, the oil tank is provided with an installation box, and the connecting bracket includes a connecting part, a first protrusion, and a second protrusion. The connecting part is located inside the oil tank and connected to a gravity ball. The end of the connecting part away from the gravity ball is fixedly connected to the first protrusion. The end of the first protrusion away from the connecting part is provided with a spring. The end of the spring away from the first protrusion is connected to the second protrusion. The end of the second protrusion away from the spring abuts against a sliding track. The spring is located inside the installation box, and the end of the spring away from the first protrusion is connected to the end of the second protrusion away from the sliding track.

[0018] By adopting the above technical solution, with the oil tank equipped with an installation box and the first and second extended parts of the connecting bracket connected by springs, the force generated by the continuous expansion and contraction of the springs during the movement of the guide rail lubrication mechanism is transmitted to the gravity ball through the connecting part, thereby realizing the opening and sealing of the oil outlet by the gravity ball, realizing the automation of the guide rail lubrication mechanism and improving its portability.

[0019] Optionally, the connecting bracket further includes a guide block, which is located at one end of the second protrusion near the sliding track, and the other end of the guide block away from the second protrusion abuts against the sliding track. The contact surfaces of the guide block and the sliding track are arc-shaped.

[0020] By adopting the above technical solution, a guide block is provided at one end of the second extension that abuts against the sliding track. The guide block carries the connecting bracket to move on the sliding track, which reduces the friction generated when the connecting bracket moves, reduces the wear of the connecting bracket, and extends the service life of the guide rail sliding.

[0021] Optionally, the inner wall of the oil tank is provided with a dovetail groove, which is arranged along the length direction of the spring. The connecting bracket also includes a guide part, one end of which is connected to the connecting part. A dovetail block is provided at the end of the guide part away from the connecting part, and the dovetail block is embedded and fits into the dovetail groove.

[0022] By adopting the above technical solution, a dovetail groove is provided on the inner wall of the oil tank, and one end of the guide part is connected to the connecting part. The end of the guide part away from the connecting part is connected to the dovetail block. The dovetail block is embedded in the dovetail groove, thereby restricting the displacement direction of the gravity ball, so that the gravity ball can only move in the vertical direction, preventing the gravity ball from deviating from its original position as it moves, and improving the stability of the guide rail lubrication mechanism.

[0023] Optionally, the oil nozzle is equipped with an integral valve.

[0024] By adopting the above technical solution and setting an integral valve on the oil nozzle, the entire guide rail lubrication mechanism can be manually controlled to determine whether oil is being dispensed, thus improving the overall controllability and portability of the guide rail lubrication mechanism.

[0025] Optionally, the oil tank has a transparent window on its side wall.

[0026] By adopting the above technical solution, and by providing a transparent window on the side wall of the oil tank, staff can easily observe the oil content in the oil tank directly through the transparent window, which can minimize the occurrence of insufficient lubricating oil and improve the portability of the guide rail lubrication mechanism.

[0027] In summary, this utility model has at least one of the following beneficial technical effects:

[0028] By setting up uneven sliding tracks and connecting the guide rail lubrication device to the flat cutting machine, the guide rail sliding device can lubricate the guide rail as the flat cutting machine moves and stop lubrication when the flat cutting machine stops moving, thus realizing the automation of the lubrication function.

[0029] By setting oil nozzles that point towards each surface of the guide rail, the guide rail lubrication device can fully lubricate the guide rail. Attached Figure Description

Detailed Implementation

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0035] This utility model discloses a guide rail lubrication mechanism for a flat cutting machine.

[0036] Reference Figures 1 to 3A guide rail lubrication mechanism for a planar cutting machine includes an oil tank 1, an opening / closing assembly 2, and an oil outlet assembly 3. The oil tank 1 is fixedly connected to the planar cutting machine and can move with the planar cutting machine. The oil tank 1 has an oil outlet 11, and the oil outlet assembly 3 is installed on the oil tank 1 to open and close as oil flows out of the oil outlet 11 as the oil tank 1 moves. The opening / closing assembly 2 is installed inside the oil tank 1 to control the oil outlet assembly 3 to dispense or close oil.

[0037] Reference Figure 2 and Figure 3 The side wall of the oil tank 1 has a transparent window 12 to facilitate the user to observe the amount of oil in the oil tank 1.

[0038] Reference Figure 2 and Figure 3 The opening and closing assembly 2 includes a sliding rail 21 and a connecting bracket 22. The connecting bracket 22 is installed inside the oil tank 1 and one end extends outside the oil tank 1. The sliding rail 21 is installed on the flatbed cutting machine and is parallel to the guide rail, and the sliding rail 21 has an abutment surface 211. The end of the connecting bracket 22 extending outside the oil tank 1 abuts against the abutment surface 211. The abutment surface 211 is continuously uneven so that the connecting bracket 22 moves up and down as it moves with the flatbed cutting machine.

[0039] refer to Figure 2 and Figure 3 The connecting bracket 22 includes a guide block 221, a second extension 222, a spring 223, a first extension 224, a connecting part 225, and a guide part 226. The guide block 221 is fixedly connected to and abuts against the sliding rail 21 at one end of the second extension 222 to control the up and down movement of the connecting bracket 22. One end of the spring 223 is welded to the end of the second extension 222 near the oil tank 1, and the other end of the spring 223 is welded to the end of the first extension 224 near the sliding rail 21 to convert the rigid movement transmitted from the second extension 222 to the first extension 224 into elastic movement.

[0040] A mounting box 13 is fixedly connected to the side of the oil tank 1 near the sliding rail 21. A spring 223 is disposed inside the mounting box 13 to ensure that the range of motion of the spring 223 is fixed when the guide rail lubrication mechanism moves, preventing the spring 223 from deviating from its original trajectory. A connecting part 225 and a first protrusion 224 are fixedly connected to one end of the oil tank 1. A gravity ball 2251 is welded to the end of the connecting part 225 away from the first protrusion 224. The gravity ball 2251 is located at the oil outlet 11 of the oil tank 1. An arc-shaped groove 14 is formed on the oil tank 1. The arc-shaped groove 14 and the oil outlet 11 are coaxially arranged. A portion of the gravity ball 2251 is embedded in the arc-shaped groove 14 and fits against each other to seal the oil outlet 11 and prevent oil in the oil tank 1 from flowing out of the oil outlet 11. A rubber pad 141 is also installed on the side wall of the arc-shaped groove 14, which partially fits against the gravity ball 2251 to prevent oil leakage caused by gaps when the gravity ball 2251 fits against the arc-shaped groove 14. A spike 22511 is also installed on the side of the gravity ball 2251 near the arc-shaped groove 14. When the gravity ball 2251 fits against the arc-shaped groove 14, the spike 22511 is embedded in the oil outlet 11 to prevent the oil outlet 11 from accumulating oil and causing blockage over time.

[0041] The guide portion 226 is fixedly connected to one end of the connecting portion 225 near the first protrusion 224. The dovetail block 2261 is fixedly connected to the end of the guide portion 226 away from the connecting portion 225. The side wall of the oil tank 1 has a dovetail groove 15, which is arranged along the height direction of the oil tank 1. The dovetail block 2261 is embedded and slidably connected in the dovetail groove 15 to guide the entire connecting bracket 22 to move along the length direction of the dovetail groove 15.

[0042] Reference Figure 3 The oil outlet assembly 3 also includes an oil outlet nozzle 31 and an integral valve 32. The oil outlet nozzle 31 is installed on the oil tank 1 and communicates with the oil outlet 11 to control the oil outlet direction. The integral valve 32 is installed on the oil outlet nozzle 31 to control the opening and closing of the oil spraying process of the oil outlet nozzle 31.

[0043] The implementation principle of the guide rail lubrication mechanism for a planar cutting machine according to this utility model embodiment is as follows: When the planar cutting machine stops working, in the stationary state of the guide rail lubrication mechanism, regardless of whether the guide block 221 is on the concave or convex surface of the sliding track 21, the gravity ball 2251 fits against the arc-shaped groove 14 of the oil outlet 11 under the action of gravity to seal the oil outlet 11. At this time, the oil nozzle 31 cannot spray oil for lubrication. When the planar cutting machine moves, it drives the connecting bracket 22 to move synchronously on the sliding track 21. At this time, the guide block 221 moves up and down along the sliding track 21, driving the gravity ball 2251 to move up and down, so that the lubricating oil can enter the oil nozzle 31 through the oil outlet 11 and be sprayed out from the oil nozzle 31 to lubricate the guide rail.

[0044] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
