Description

Technical Field

[0001] This utility model relates to the field of modular hydraulic technology, and in particular to a modular hydraulic transmission device. Background Technology

[0002] In the field of industrial production, with the continuous improvement of automation and the increasing complexity of production processes, the requirements for power transmission and mechanical motion control are becoming more and more refined. Traditional hydraulic equipment has relatively simple functions and cannot meet the complex needs of performing multiple actions and functions at the same time. Therefore, a modular combined hydraulic transmission equipment is needed.

[0003] In some automated production lines, precise hydraulic drives are needed to operate robotic arms for material handling and component assembly, while extraction systems are required to clean up debris and dust generated during processing or to provide a vacuum environment for certain processing steps. Currently, hydraulic oil leaks occur at the connection points between modules or at the mating points of internal components. Due to the modular design requiring the combination of multiple components, there are many connection points. At the interface of the hydraulic pump and hydraulic motor module, the seals are prone to aging and damage, causing hydraulic oil to flow from the high-pressure area to the low-pressure area, resulting in a drop in system pressure and affecting the power output of the equipment. Existing solutions control the cylindricity and surface roughness of the interface to a very small range, allowing the seals to better fit the interface surface. High-precision CNC machining equipment can ensure the accuracy of the interface dimensions and reduce poor sealing caused by dimensional deviations. However, focusing too much on interface leakage can lead to an overemphasis on sealing performance, affecting power stability. High-precision interface machining increases the rigidity of the connection points, making it impossible to buffer pressure changes through elastic deformation as before when the hydraulic system pressure fluctuates. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a modular combined hydraulic transmission device, including a fixed box 1. A fixed plate 3 is fixedly connected to the bottom right side of the outer wall of the fixed box 1. A hydraulic pump 4 is fixedly connected to the top front side of the fixed plate 3. A push rod 5 is fixedly connected to the top rear side of the fixed plate 3. A hydraulic cylinder 6 is provided on the rear side of the inner wall of the fixed box 1. The output end of the push rod 5 passes through the right side of the outer wall of the fixed box 1 and is slidably connected to the inner wall of the right end of the hydraulic cylinder 6. Two connecting pipes 7 are connected to the left and right ends of the front side of the outer wall of the hydraulic cylinder 6. The front ends of the two connecting pipes 7 are connected to an air extraction cylinder 9. An air extraction pipe 8 is provided on the right end of the air extraction cylinder 9. The output end of the hydraulic pump 4 passes through the right side of the outer wall of the fixed box 1 and is fixedly connected to the air extraction pipe 8. A moving column 11 is slidably connected to the inner wall of the air extraction cylinder 9. Moving disks 10 are fixedly connected to the left and right sides of the outer wall of the moving column 11. A heat dissipation mechanism 2 is provided in the middle of the bottom end of the fixed plate 3. The heat dissipation mechanism 2 is used for cooling.

[0032] Specifically, the fixed box 1 serves as the basic support, constructed with robust materials. Its right bottom fixed plate 3 supports key components. The hydraulic pump 4 is located in front of the fixed plate 3. Upon power-on, its internal precision structure operates at high speed, transforming into a powerful power source. The rear push rod 5 is always ready. Upon receiving a command, its output end smoothly penetrates the side wall of the fixed box 1 and precisely embeds into the inner wall of the right end of the hydraulic cylinder 6, driving its operation. The hydraulic cylinder 6 is hidden behind the inner wall of the fixed box 1. Its excellent cylinder body efficiently converts mechanical thrust into hydraulic energy, which is then transmitted through the connecting pipes 7 on both sides of the outer wall. The connecting pipes 7 lead to the air extraction cylinder 9. The air extraction pipe 8 at the right end of the air extraction cylinder 9 is connected to the hydraulic pump 4. When the hydraulic pump 4 is working, it not only supplies power for the hydraulic transmission but also creates negative pressure for the air extraction cylinder 9 with the help of the air extraction pipe 8. The moving column 11 and the moving disc 10 inside the air extraction cylinder 9 move in coordination with the influx of hydraulic oil and the negative pressure suction. All components are interlocked to ensure the stable operation of the equipment.

[0033] Reference Figure 2 , Figure 3 and Figure 4 The heat dissipation mechanism 2 includes a fixed box 201. The top of the outer wall of the fixed box 201 is fixedly connected to the middle of the bottom of the fixed plate 3. A micro motor 202 is fixedly connected to the middle of the bottom of the inner wall of the fixed box 201. A bevel gear 203 is fixedly connected to the output end of the micro motor 202. Two fixed rods 204 are fixedly connected to the left and right sides of the bottom of the inner wall of the fixed box 201. A rotating column 205 is rotatably connected to the top of each of the two fixed rods 204. Multiple bevel gears are fixedly connected to both ends of each of the two rotating columns 205. Wheel 206, the outer left and right sides of bevel gear 1 203 are meshed with the adjacent end of bevel gear 206, the top left and right sides of the inner wall of fixed box 201 are fixedly connected to two fixed rods 207, the adjacent side of the two fixed rods 207 is rotatably connected to a rotating fan 209, the bottom end of the two rotating fans 209 is fixedly connected to a bevel gear 3 208, the two bevel gears 3 208 are meshed with the far end of bevel gear 206, and the top center of fixed plate 3 is fixedly connected to an air outlet box 210.

[0034] Specifically, the fixed box 201 is firmly connected to the bottom center of the fixed plate 3, providing a safe space for the internal components. The micro motor 202 in the bottom center of its inner wall starts running quickly, and the output end drives the bevel gear 1 203 to rotate rapidly. The bevel gear 1 203 meshes tightly with the bevel gear 206 at both ends of the rotating column 205 supported by the fixed rod 1 204 on both sides of the bottom of the fixed box 201. The power is instantly transmitted. The bevel gear 206 on the rotating column 205 then precisely drives the bevel gear 3 208 at the bottom of the rotating fan 209, causing the rotating fan 209 to rotate at high speed. With the assistance of the fixed rod 207, the rotating fan 209 flexibly cuts the air, and a large amount of cold air is drawn into the fixed box 201 to fully exchange heat. Then the hot air is smoothly discharged through the air outlet box 210 in the middle of the top of the fixed plate 3, continuously circulating, keeping the equipment in a good temperature environment and ensuring stable operation.

[0035] Reference Figure 1 , Figure 2 and Figure 5 The bottom left and right sides of the fixed box 1 are provided with two brackets 12. The top front and rear sides of the outer wall of the two brackets 12 are threaded with multiple screws 13, which are threaded to the bottom of the fixed box 1. The top left side of the fixed box 1 is fixedly connected with a cover plate 14, and the right side of the inner wall of the cover plate 14 is slidably connected with a movable plate 15. The top right side of the movable plate 15 is provided with an installation groove 16, and the inner wall of the installation groove 16 is fixedly connected with a handle 17.

[0036] Specifically, two brackets 12 are provided on the left and right sides of the bottom of the fixed box 1. Multiple screws 13 are threaded to the top front and rear sides of the outer wall of the two brackets 12. These screws 13 are threaded to the bottom of the fixed box 1 to provide stable support for the fixed box 1. A cover plate 14 is fixedly connected to the top left side of the fixed box 1. A movable plate 15 is slidably connected to the inner right side of the cover plate 14. An installation groove 16 is opened on the top right side of the movable plate 15. A handle 17 is fixedly connected to the inner wall of the installation groove 16. The movable plate 15 can be operated as needed to adjust the internal spatial layout of the equipment or to perform maintenance operations.

[0037] Reference Figure 2 , Figure 3 and Figure 5Two fixing blocks 18 are fixedly connected to the front and rear ends of the right side of the outer wall of the fixing box 1. Two connecting rods 19 are fixedly connected to the outer walls of the two fixing blocks 18. Two connecting blocks 20 are fixedly connected to the front and rear ends of the top right side of the fixing plate 3. The outer walls of the two connecting blocks 20 are fixedly connected to the right ends of the connecting rods 19. A control button 21 is fixedly connected to the middle of the right side of the fixing box 1. The control button 21 is electrically connected to the micro motor 202. Two connecting pieces 22 are fixedly connected to the front and rear ends of the right side of the outer wall of the air outlet box 210. The bottom of the two connecting pieces 22 is threaded to the top right side of the fixing plate 3.

[0038] Specifically, the fixing blocks 18 at the front and rear ends of the right side of the outer wall of the fixed box 1 are connected to the connecting blocks 20 at the front and rear ends of the top right side of the fixed plate 3 via connecting rods 19, which further enhances the connection stability between the fixed box 1 and the fixed plate 3. When the control button 21 in the middle of the right side of the fixed box 1 is pressed, the operation of the micro motor 202 can be controlled because the control button 21 is electrically connected to the micro motor 202. The connecting pieces 22 at the front and rear ends of the right side of the outer wall of the air outlet box 210 are threadedly connected to the top right side of the fixed plate 3, ensuring the stability of the position of the air outlet box 210. During the operation of the equipment, the various components cooperate with each other to complete hydraulic transmission and related gas processing operations.

[0039] Working Principle: When the hydraulic pump 4 on the fixed plate 3 is powered on, the internal impeller rotates at high speed, generating powerful force. Simultaneously, the push rod 5 receives an instruction and starts, its output end precisely penetrating the side wall of the fixed box 1 and smoothly inserting into the inner wall of the right end of the hydraulic cylinder 6, applying mechanical thrust to the hydraulic cylinder 6. Under this force, the hydraulic oil inside the cylinder 6 is squeezed, causing a sudden pressure increase. This pressure then rapidly flows through the connecting pipes 7 on both sides of the outer wall towards the suction cylinder 9. The moving column 11 and the moving discs 10 on the left and right sides of the suction cylinder 9 are forced to slide inside the cylinder under the combined impact of the high-pressure hydraulic oil and the negative pressure suction. The moving discs 10 serve a sealing and auxiliary pushing function, making the suction process more efficient, realizing the transfer and utilization of hydraulic energy, and meeting the equipment's needs under different working conditions.

[0040] Furthermore, it is fixed to the bottom center of the fixed plate 3 by the fixed box 201. When it needs to work, the micro motor 202 in the bottom center of its inner wall receives the signal and starts to run. The output end drives the bevel gear 203 to rotate rapidly. The bevel gear 203 meshes with the bevel gears 206 at both ends of the rotating column 205, which is supported by the fixed rod 204 on both sides of the bottom of the fixed box 201 and can rotate flexibly. This causes the rotating column 205 and the bevel gears 206 on it to rotate together. 206 precisely meshes with the bevel gear 208 at the bottom of the rotating fan 209, driving the bevel gear 208 to rotate. This, in turn, causes the rotating fan 209 to rotate at high speed with the assistance of the fixed rod 207. The rotating fan 209 draws a large amount of cold air into the fixed box 201, where it fully contacts and exchanges heat with the equipment. Finally, the air is smoothly discharged through the air outlet box 210 at the top center of the fixed plate 3, forming a continuous heat dissipation cycle. This ensures that the equipment will not malfunction due to overheating and will always maintain a good operating condition.

[0041] 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.
