Description

Technical Field

[0001] This utility model relates to the field of fluid transmission and control technology, specifically to an automatic oil injection and lubrication mechanism for a CNC vertical-horizontal conversion swing head. Background Technology

[0002] In modern manufacturing, CNC machine tools are rapidly developing towards higher speed, higher precision, and more complex designs. Among them, the vertical-to-horizontal conversion swivel head, as a core functional component, directly determines the overall machining quality through its operating accuracy and stability.

[0003] Existing automatic oil filling solutions mostly rely on sensors and electrically controlled solenoid valves to achieve timed automatic oil filling. This not only requires an additional control system, increasing equipment costs, but also makes the solenoid valves and sensors prone to failure under oily or vibrating conditions. Some solutions use a manual shutdown oil filling mode, where operators need to open the protective cover every once in a while to add oil. Manual judgment can easily lead to missed or excessive filling.

[0004] Therefore, an automatic oiling and lubrication mechanism for a CNC vertical-horizontal conversion swing head is proposed to solve the problems mentioned above. Utility Model Content

[0023] 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. Example:

[0024] Please see Figure 1 - Figure 5 An automatic oiling and lubrication mechanism for a CNC vertical-horizontal convertible swivel head in this embodiment includes a base 1, a lifting platform 2 fixedly mounted on the upper end of the base 1, a loading platform 3 slidably mounted on the upper end of the base 1, at least two sliding limit posts 4 fixedly mounted on the outer side of the lifting platform 2, a sliding seat 5 slidably mounted on the outer side of the sliding limit posts 4, a swivel head shell 7 and a swivel head drive shell 16 fixedly mounted on the side of the sliding seat 5 near the loading platform 3, a hydraulic column 6 fixedly mounted on the outer side of the lifting platform 2, and a vertical-horizontal swivel head rotatably mounted between the swivel head shell 7 and the swivel head drive shell 16. 8. An oil storage box 9 is fixedly installed at the upper end of the swing head housing 7 and the swing head drive housing 16. An oil injection pipe 24 is fixedly installed at the lower end of the oil storage box 9. The oil injection pipe 24 extends into the bearing cavity inside the swing head drive housing 16. An oil filling pipe 10 and a rotating motor 13 are fixedly installed at the upper end of the oil storage box 9. A drive column 11 is rotatably installed at the upper end of the oil filling pipe 10. An oil filling port sealing column 19 is slidably installed inside the oil filling pipe 10. An oil filling port sealing column 20 is fixedly installed at the lower end of the oil filling port sealing column 19. An extension column 21 is fixedly installed at the upper end of the oil filling port sealing column 19.

[0025] When lubricating oil needs to be replenished in the oil reservoir 9, the rotating motor 13 is started. The starting of the rotating motor 13 drives the drive column 11 to rotate, and the rotation of the drive column 11 drives the extension column 21 to move downward. The movement of the extension column 21 causes the filler port sealing column 19 and the filler port sealing column 20 to move downward synchronously. As the filler port sealing column 19 gradually moves, a gap appears inside the filler pipe 10. At this time, the filler port sealing column 20 moves into the filler pipe 24. Then the rotating motor 13 is stopped, and lubricating oil is replenished into the oil reservoir 9 through the drive column 11 and the filler pipe 10. After the oil filling is completed, the rotating motor 13 is started in reverse, causing the filler port sealing column 19, the filler port sealing column 20, and the extension column 21 to move upward until the filler port sealing column 19 blocks the filler pipe 10. At this time, the filler port sealing column 20 is closed. The lower end of the plug 20 remains inside the oil injection pipe 24, creating a sealing effect on the oil injection pipe 24. When the equipment is ready to automatically lubricate, the forward and reverse rotation and rotation speed of the rotating motor 13 are controlled. First, the rotating motor 13 is slowly rotated in the reverse direction, causing the oil filling port plug 19, the oil injection port plug 20, and the extension column 21 to move upward until the oil injection port plug 20 disengages from the oil injection pipe 24, thereby injecting oil into the bearing inside the swing head drive housing 16. Then, the rotating motor 13 rotates in the forward direction, causing the oil filling port plug 19, the oil injection port plug 20, and the extension column 21 to move downward until the oil injection pipe 24 is blocked, and the oil filling port plug 19 is about to release the blockage of the oil filling pipe 10. Then, the rotating motor 13 rotates in the reverse direction again, thus completing one automatic oil injection cycle.

[0026] The lifting platform 2 is located on the upper edge of the base 1. The lifting platform 2 and the platform 3 are horizontally distributed. The sliding limit post 4 is located on the side of the lifting platform 2 near the platform 3. The swing head shell 7 is located above the platform 3.

[0027] The lifting platform 2 is located at the edge of the base 1, which can save space in the middle of the base 1 and reserve a larger sliding stroke for the platform 3. The sliding limit post 4 is located on the side of the lifting platform 2 close to the platform 3, which shortens the distance between the slide 5 and the platform 3.

[0028] The hydraulic column 6 is positioned between the two sliding limit columns 4, and the lower end of the hydraulic column 6 is fixedly connected to the upper end of the slide block 5.

[0029] The hydraulic column 6 is positioned between the two sliding limit columns 4 to ensure that the slide block 5 is subjected to uniform force, thereby preventing the slide block 5 from tilting due to uneven load during lifting and lowering, and ensuring the lifting accuracy of the slide block 5.

[0030] A rotating column 14 is fixedly connected to the output end of the rotating motor 13. A drive gear 15 is fixedly installed on the upper end of the rotating column 14. A rotating gear 12 is fixedly installed on the outer side of the drive column 11. The rotating gear 12 is meshed with the drive gear 15.

[0031] When the rotating motor 13 starts, the rotating motor 13 drives the rotating column 14 to rotate, the rotating column 14 drives the drive gear 15 to rotate, the drive gear 15 drives the rotating gear 12 that meshes with it to rotate, and the rotating gear 12 in turn drives the drive column 11 to start rotating.

[0032] A transmission column 22 is fixedly installed on the outside of the extension column 21, and an arc-shaped drive groove 23 is opened through the outside of the drive column 11, with the transmission column 22 installed inside the arc-shaped drive groove 23.

[0033] As the drive column 11 rotates, the structure of the arc-shaped drive groove 23 drives the transmission column 22 and the extension column 21 to move up and down. The arc-shaped drive groove 23 is designed to prevent lubricating oil from flowing out when oil is poured gently.

[0034] The drive column 11 is a hollow cylindrical structure, and the filler pipe 10 is a multi-segment hollow structure, divided into upper and lower parts. The upper part of the filler pipe 10 is a cylindrical structure, and the lower part is a gradually increasing conical structure. The filler port sealing column 19 is a cylindrical structure, and the size of the cavity of the filler port sealing column 19 is the same as that of the upper part of the filler pipe 10. The filler port sealing column 20 is a cylindrical structure, and the size of the cavity of the filler pipe 24 is the same as that of the filler pipe 24.

[0035] When the filler port sealing column 19 moves inside the filler pipe 10, it blocks the filler pipe 10 as it moves to the upper part of the filler pipe 10. As it moves to the lower part of the filler pipe 10, the sealing effect is released, allowing for oil filling. When the filler port sealing column 20 moves into the filler pipe 24, it blocks the filler pipe 24. When the filler port sealing column 20 detaches from the filler pipe 24, automatic oil filling is achieved. The filler port sealing column 19 and the filler port sealing column 20 are made of oil-resistant elastic material, such as rubber.

[0036] The working principle of the above embodiment is as follows: When it is necessary to replenish lubricating oil to the oil storage box 9 at the upper end of the sway head shell 7 and the sway head drive shell 16, the rotating motor 13 at the upper end of the oil storage box 9 is started. The rotating motor 13 drives the rotating column 14 fixed at the output end to rotate. The rotating column 14 drives the driving gear 15 fixed at the upper end to rotate. The driving gear 15 meshes with the rotating gear 12 fixed on the outside of the driving column 11, causing the driving column 11 to rotate around the oil filling pipe 10. The arc-shaped driving groove 23 on the outside of the driving column 11 drives the transmission column 22 on the outside of the extension column 21, thereby causing the extension column 21 to drive the oil filling port sealing column 19 and the oil filling port sealing column 20 fixed at the lower end to move down synchronously. The oil filling port sealing column 19 moves to the lower part of the oil filling pipe 10, and a gap appears inside the oil filling pipe 10. At this time, lubricating oil can be replenished to the oil storage box 9 through the oil filling pipe 10. After replenishing the oil, the rotating motor 13 is started in reverse, causing the oil filling port sealing column 19 and the oil filling port sealing column 20 to move down synchronously. The plug 20 moves upward and resets with the extension 21, sealing the oil injection pipe 24 and the oil filling pipe 10. When the equipment needs automatic lubrication, the control motor 13 slowly reverses, driving the oil filling port plug 19 and the oil injection port plug 20 upward until the oil filling port plug 20 disengages from the oil injection pipe 24. The lubricating oil in the oil storage box 9 flows into the bearing cavity inside the swing head drive housing 16 through the oil injection pipe 24. Then the motor 13 rotates forward, causing the plug to move downward and block the oil injection pipe 24, and the oil filling port plug 19 is close to releasing the blockage of the oil filling pipe 10. Then the motor 13 rotates in reverse again, thus completing one automatic oil injection cycle. The forward and reverse rotation of the motor 13 is controlled by the output signal of the CNC equipment. The CNC equipment sends a signal to the driver of the motor 13 to drive the motor 13 to rotate forward or in reverse. The cycle of oil injection is realized by preset signal sending time of the CNC equipment.

[0037] The use of CNC equipment and the control of the rotating motor 13 by CNC equipment are common existing technologies. The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. They are common knowledge in the field. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
