Description

Technical Field

[0001] This utility model belongs to the field of milling head processing technology, and in particular relates to a universal milling head with automatic lubrication function. Background Technology

[0002] As a key component in the field of machining, the performance of the universal milling head directly affects machining accuracy and efficiency.

[0003] During milling, the mating parts between the milling cutter head and the connecting end are prone to wear due to high-speed rotation and frequent loads, directly affecting machining accuracy and shortening equipment life. Continuous and reliable lubrication is necessary to reduce friction, lower temperature rise, and extend service life. Traditional universal milling heads rely heavily on manual, periodic lubrication, which can easily lead to untimely or uneven lubrication, causing abnormal wear or even sudden malfunctions, posing safety hazards.

[0004] Therefore, those skilled in the art have proposed a universal milling head with automatic lubrication function. Utility Model Content

[0005] The purpose of this utility model is to provide a universal milling head with automatic lubrication function in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a universal milling head with automatic lubrication function, comprising a connecting end, an oil reservoir being provided inside the connecting end, a working groove being provided inside the connecting end and on one side of the oil reservoir, a button being slidably connected inside the working groove, a limiting groove being symmetrically provided inside the connecting end and on one side of the working groove in an upper and lower structure, a limiting cylinder being symmetrically fixedly connected to one side of the button, one end of the limiting cylinder extending into the interior of the limiting groove, a second spring being sleeved on the outer side of the limiting cylinder and between the button and the inner wall of the working groove, and a movable plate being fixedly connected to one side of the button and between the two limiting cylinders.

[0007] Preferably, the oil storage tank is internally slidably connected to a lifting plate, and the top of the lifting plate and the bottom of the moving plate are both configured as mutually cooperating inclined structures.

[0008] Preferably, the bottom of the connecting end is provided with a threaded hole and a milling cutter is connected to it by an internal hex bolt.

[0009] Preferably, a first spring 8 is fixedly connected inside the connecting end and between the lifting plate and the oil storage tank.

[0010] Preferably, an oil inlet is provided inside the connecting end and on one side of the oil storage tank, and an oil cap is threadedly connected to the inside of the oil inlet.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] 1. This device has a good automatic reset function, which effectively ensures the stability and reliability of the device. When the button is released, the lifting plate resets under the action of the first spring's rebound force, and the lifting plate pushes the moving plate backward. This automatic reset allows the device to quickly return to its initial state after each lubrication operation, preparing it for the next lubrication.

[0013] 2. It avoids uneven lubrication or device malfunctions that may result from parts not being reset, ensuring the consistency and stability of lubrication effect; on the other hand, it reduces the need for manual intervention and adjustment, lowers the risk of human error, and extends the service life of the device.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a universal milling head with automatic lubrication function, including a connecting end 1, an oil storage groove 7 is provided inside the connecting end 1, a working groove 5 is provided inside the connecting end 1 and on one side of the oil storage groove 7, a button 2 is slidably connected inside the working groove 5, a limiting groove 14 is symmetrically provided inside the connecting end 1 and on one side of the working groove 5 in an upper and lower structure, a limiting cylinder 13 is symmetrically fixedly connected to one side of the button 2, one end of the limiting cylinder 13 extends into the interior of the limiting groove 14, a second spring 16 is sleeved on the outer side of the limiting cylinder 13 and between the button 2 and the inner wall of the working groove 5, and a moving plate 15 is fixedly connected to one side of the button 2 and between the two limiting cylinders 13.

[0021] In this embodiment: when the user presses button 2, button 2 pushes the limiting cylinder 13 to slide in the limiting groove 14. At the same time, button 2 pushes the moving plate 15 to move forward. At this time, the moving plate 15 pushes the lifting plate 9 to move downward in the oil storage tank 7. When the limiting cylinder 13 touches the bottom of the limiting groove 14, button 2 is released and button 2 is reset by the second spring 16.

[0022] In a preferred embodiment, a lifting plate 9 is slidably connected inside the oil storage tank 7, and the top of the lifting plate 9 and the bottom of the moving plate 15 are both configured as mutually cooperating inclined structures.

[0023] In this embodiment: when the moving plate 15 pushes the lifting plate 9, the lifting plate 9 moves downward inside the oil storage tank 7.

[0024] In a preferred embodiment, the bottom of the connecting end 1 is provided with a threaded hole and is connected to a milling cutter 4 by an internal hex bolt 10. The bottom of the oil storage tank 7 and the top of the threaded hole are both embedded with metal plates 11. A hollow rubber pipe 12 is fixedly connected inside the connecting end 1 and between the two metal plates 11.

[0025] In this embodiment, the milling cutter disc 4 and the connecting end 1 are fixedly connected by the internal hex bolt 10. When the lifting plate 9 moves downward inside the oil reservoir 7, it will put pressure on the lubricating oil inside the oil reservoir 7. Under the action of pressure, the lubricating oil flows through the hollow rubber pipe 12, causing the lubricating oil to slide down to the internal hex bolt 10.

[0026] In a preferred embodiment, a first spring 8 is fixedly connected inside the connecting end 1 and between the lifting plate 9 and the oil storage tank 7.

[0027] In this embodiment: when the lifting plate 9 moves downward inside the oil storage tank 7, the lifting plate 9 applies pressure to the first spring 8. At this time, when the button 2 is released, the first spring 8 rebounds, helping the lifting plate 9 to reset.

[0028] In a preferred embodiment, an oil inlet 6 is provided inside the connecting end 1 and on one side of the oil storage tank 7, and an oil cap 3 is threadedly connected inside the oil inlet 6.

[0029] In this embodiment: when the injection of lubricating oil into the oil inlet 6 is finished, the oil cap 3 is covered, so that the oil inlet 6 is internally threaded with the oil cap 3, and the oil cap 3 prevents the lubricating oil from being directly exposed to the air.

[0030] Working principle: In actual use, the user injects lubricating oil into the oil reservoir 7, and after filling, covers it with the oil cap 3. At this time, the user presses button 2, which pushes the limiting cylinder 13 to move within the limiting groove 14. Since the moving plate 15 is fixedly connected to button 2, button 2 will drive the moving plate 15 to move forward. When the moving plate 15 moves forward, it will give a pushing force to the lifting plate 9. At this time, the lifting plate 9 moves downward within the oil reservoir 7, and the lifting plate 9 squeezes the lubricant. The lubricant slides through the hollow rubber tube 12 onto the internal hex bolt 10, which plays a lubricating role. At this time, button 2 is released, and the lifting plate 9 returns to its original position under the action of the return force of the first spring 8. At this time, the lifting plate 9 pushes the moving plate 15 to move backward, and button 2 returns to its original position under the action of the return force of the second spring 16.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
