Hydraulic motor driven feeding mechanism

Abstract

This invention relates to the field of hydraulic motor technology and discloses a hydraulic motor-driven feeding mechanism, including a drive motor device body. A fixed housing is fixedly connected to the top of the drive motor device body, and an internally threaded tube is fixedly installed at the bottom inside the fixed housing. A threaded post is connected to the internal threads of the internally threaded tube. This hydraulic motor-driven feeding mechanism, by setting a first gear, a second gear, and a threaded post, utilizes the threaded connection between the threaded post and the internally threaded tube to allow the connecting post to rise and fall smoothly. The first gear has more teeth than the second gear. Therefore, during the rising and falling of the threaded post, when the main meshing gear on the output shaft surface contacts and rotates with the first or second gear, the rotational speed of the main meshing gear slows down or speeds up, resulting in a stronger or weaker rotational meshing force. This achieves the purpose of adjusting the feeding force, facilitating the conveying of materials of different weights.

Description

Technical Field

[0001] This invention relates to the field of hydraulic motor technology, specifically to a hydraulic motor-driven feeding mechanism. Background Technology

[0002] A rolling mill is a piece of equipment that realizes the metal rolling process. It generally refers to a device that completes the entire process of rolling production. It consists of rolls, mill stand, bearing housing, bearings, self-contained take-up and unwinding platform, base, roll adjustment device, upper roll balancing device, and roll changing device. The hydraulic motor is the driving energy of the rolling mill's feeding mechanism. The hydraulic motor converts the liquid pressure energy provided by the hydraulic pump into the mechanical energy of its output shaft, thereby conveying the material.

[0003] Existing hydraulic motors generate a constant pushing force during operation, which can easily lead to problems when encountering heavy materials, affecting work efficiency. In addition, hydraulic motors use oil as their power source, but the oil intake cannot be controlled during the oil absorption process. Too much or too little oil will increase the damage rate of the hydraulic motor. Therefore, this invention provides a hydraulic motor-driven pushing mechanism. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a hydraulic motor-driven feeding mechanism, which has the advantages of easy control of rotational speed and oil discharge volume. It solves the problems mentioned in the background art, such as the constant driving force generated by existing hydraulic motors during operation, which easily leads to the inability to transport heavy materials, and the inability to control the oil intake during oil absorption, with both excessive and insufficient oil discharge increasing the damage rate of the hydraulic motor.

[0005] The present invention provides the following technical solution: a hydraulic motor-driven feeding mechanism, comprising a drive motor device body, a fixed sleeve fixedly connected to the top of the drive motor device body, an internally threaded tube fixedly installed at the bottom of the fixed sleeve, a threaded post internally threaded into the internally threaded tube, a connecting sleeve fixedly installed at the top of the threaded post, a connecting shaft fixedly engaged inside the connecting sleeve, a first gear movably sleeved on the surface of the connecting shaft, a fixed shaft fixedly connected to the top of the connecting sleeve, another connecting sleeve fixedly connected to the top of the fixed shaft, another connecting shaft fixedly engaged inside the other connecting sleeve, a second gear movably sleeved on the surface of the other connecting shaft, and a connecting post fixedly connected to the top of the other connecting sleeve.

[0006] Preferably, the surface of the drive motor device body is provided with a wall groove, a connecting pipe is fixedly connected inside the wall groove, an oil storage device shell is fixedly installed on the side of the connecting pipe, two extension blocks are fixedly connected to one side of the inner wall of the oil storage device shell, a fixing plate is fixedly snapped onto the side of the two extension blocks, a spring is fixedly installed on the side of the fixing plate, and a second L-shaped connecting plate is fixedly installed on the side of the spring.

[0007] Preferably, the top of the fixed sleeve is provided with a top groove, and a connecting column is movably connected inside the top groove.

[0008] Preferably, a connecting handle is fixedly attached to the surface of the connecting column, and a main meshing gear meshes with the surfaces of the first gear and the second gear.

[0009] Preferably, an output shaft is movably connected to the side of the fixed housing, a main meshing gear is fixedly engaged on the surface of the output shaft, and a limit plate is fixedly engaged on the surface of the connecting shaft.

[0010] Preferably, a first L-shaped connecting plate is fixedly installed on the inner wall of the connecting pipe, the internal structure of the first L-shaped connecting plate and the second L-shaped connecting plate are the same, a connecting pipe port is fixedly installed on the side of the oil storage equipment shell, and a sealing cap is provided on the surface of the connecting pipe port.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The hydraulic motor-driven feeding mechanism, by setting a first gear, a second gear and a threaded column, utilizes the threaded connection between the threaded column and the internal threaded tube to make the connecting column rise and fall smoothly. The number of teeth on the surface of the first gear is greater than the number of teeth on the surface of the second gear. Thus, when the main meshing gear on the surface of the output shaft contacts and rotates with the first gear or the second gear during the lifting and lowering of the threaded column, the rotational speed of the main meshing gear is slowed down or sped up, and the resulting rotational biting force is stronger or weaker, thereby achieving the purpose of adjusting the pushing force and facilitating the conveying of materials of different weights.

[0013] 2. The hydraulic motor-driven feeding mechanism, through the setting of a spring, a first L-shaped connecting plate and a second L-shaped connecting plate, ensures normal oil input when the oil output speed is normal. When the oil output speed is too fast, the oil exerts a pushing force on the second L-shaped connecting plate, causing the spring to contract and gradually reducing the distance between the first L-shaped connecting plate and the second L-shaped connecting plate. This achieves adaptive control of the oil volume and reduces the failure rate. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-4The hydraulically driven feeding mechanism includes a drive motor body 1, a fixed housing 2 fixedly connected to the top of the drive motor body 1, an internally threaded tube 13 fixedly installed at the bottom inside the fixed housing 2, and a threaded post 23 internally threadedly connected to the internally threaded tube 13. The threaded connection between the threaded post 23 and the internally threaded tube 13 allows the connecting post 4 to rise and fall smoothly, preventing wobbling during the meshing rotation of the main meshing gear 11 driving the first gear 20 or the second gear 25. A connecting housing 21 is fixedly installed on the top of the threaded post 23, and a connecting shaft 24 is fixedly engaged inside the connecting housing 21. The surface of the first gear 20 is movably sleeved with the first gear 20. The top of the connecting sleeve 21 is fixedly connected to the fixed shaft 19. The top of the fixed shaft 19 is fixedly connected to another connecting sleeve 21. The inside of the other connecting sleeve 21 is fixedly snapped with another connecting shaft 24. The surface of the other connecting shaft 24 is movably sleeved with the second gear 25. The top of the other connecting sleeve 21 is fixedly connected to the connecting column 4. The number of teeth on the surface of the first gear 20 is greater than the number of teeth on the surface of the second gear 25. Therefore, when it contacts the main meshing gear 11, it passively controls the rotation speed and biting force of the main meshing gear 11, which is convenient for conveying materials of different weights.

[0021] The drive motor equipment body 1 has a wall groove 6 on its surface. A connecting pipe 7 is fixedly connected inside the wall groove 6. An oil storage device shell 8 is fixedly installed on the side of the connecting pipe 7. Two extension blocks 17 are fixedly connected to one side of the inner wall of the oil storage device shell 8. A fixing plate 18 is fixedly snapped onto the side of the two extension blocks 17. A spring 16 is fixedly installed on the side of the fixing plate 18. A second L-shaped connecting plate 15 is fixedly installed on the side of the spring 16. When the oil delivery speed is too fast, the oil liquid exerts a pushing force on the second L-shaped connecting plate 15, causing the spring 16 to contract and gradually reduce the distance between the first L-shaped connecting plate 14 and the second L-shaped connecting plate 15, thereby achieving the purpose of adaptive control of the oil volume.

[0022] The top of the fixed housing 2 is provided with a top groove 12, and a connecting column 4 is movably connected inside the top groove 12.

[0023] Among them, the connecting handle 5 is fixedly snapped onto the surface of the connecting column 4, and the main meshing gear 11 is engaged with the surfaces of the first gear 20 and the second gear 25. When the main meshing gear 11 on the surface of the output shaft 3 contacts and rotates with the first gear 20 or the second gear 25 during the lifting and lowering process of the threaded column 23, the rotational speed of the main meshing gear 11 slows down or speeds up, and the resulting rotational biting force becomes stronger or weaker, thereby achieving the purpose of adjusting the pushing force.

[0024] The fixed housing 2 is movably connected to the side of the output shaft 3, the surface of the output shaft 3 is fixedly engaged with the main meshing gear 11, and the surface of the connecting shaft 24 is fixedly engaged with the limit plate 22.

[0025] Among them, a first L-shaped connecting plate 14 is fixedly installed on the inner wall of the connecting pipe 7. When the oil output speed is normal, the spring 16 drives the second L-shaped connecting plate 15 to be placed at the free tension position of the spring 16, forming an alternation with the first L-shaped connecting plate 14 to ensure normal oil input. The internal structure of the first L-shaped connecting plate 14 and the second L-shaped connecting plate 15 is the same. A connecting pipe port 10 is fixedly installed on the side of the oil storage equipment shell 8, and a sealing cover 9 is provided on the surface of the connecting pipe port 10.

[0026] Working principle: During operation, when the operator needs to adjust the driving force of the output shaft 3, the connecting handle 5 controls the threaded post 23 fixedly installed on the two connecting sleeves 21 at the bottom of the connecting shaft 24 to rotate the internal threaded tube 13 at the bottom of the fixed sleeve 2. This causes the first gear 20 and the second gear 25 on the surface of the fixed shaft 19 inside the two connecting sleeves 21 to rise and fall. Utilizing the fact that the number of teeth on the surface of the first gear 20 is greater than the number of teeth on the surface of the second gear 25, the main meshing gear 11 on the surface of the output shaft 3 meshes with either the first gear 20 or the second gear. When wheel 25 rotates, it slows down or speeds up the rotational speed of the main meshing gear 11, resulting in a stronger or weaker rotational meshing force. When the oil output speed is normal, spring 16 drives the second L-shaped connecting plate 15 to be positioned at the free tension position of spring 16, forming an interlocking structure with the first L-shaped connecting plate 14 to ensure normal oil input. When the oil output speed is too fast, the oil exerts a pushing force on the second L-shaped connecting plate 15, causing spring 16 to contract and gradually reduce the distance between the first L-shaped connecting plate 14 and the second L-shaped connecting plate 15, indirectly reducing the gap for oil discharge.
