DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 2-Figure 4The utility model provides an embodiment: a dual-pump main shaft connection support structure, including two connecting blocks 2, the bottom of the connecting block 2 is rotatably connected with a connecting block 1, the outside of the connecting block 1 is fixedly connected with a fixed block 11, the inside of the fixed block 11 is slidably connected with a push rod 12, the inside of the fixed block 11 is slidably connected with a plug-in block 15, the plug-in block 15 is slidably connected with a baffle 13, the outside of the baffle 13 is fixedly connected with a spring 14, the bottom of the plug-in block 15 is fixedly connected with a baffle 21, the bottom of the baffle 21 is fixedly connected with a spring 21, the outside of the connecting block 1 is fixedly connected with a fixed block 217, the inside of the fixed block 21 is slidably connected with a baffle 21, a circulation component is arranged at the bottom of the connecting block 2, two main shafts 4 are rotatably connected between the connecting block 22 and the connecting block 1, and the two main shafts 4 are connected by flanges.

[0032] Specifically, when disassembling, push the push rod 12 into the fixed block 11, and then squeeze out the baffle 13, so that the spring 14 is compressed, so that the plug-in block 15 slides down and compresses the spring 2 16 until the two are separated. Then open the fixed block 11 to facilitate the removal of the main shaft 4. When installing, first place the main shaft 4 on the connecting block 2, rotate the connecting block 1, and then press the baffle 13 to release the spring 2 16, so that the baffle 21 and the plug-in block 15 rise, and then the spring 14 recovers, so that the baffle 13 is re-placed in the fixed block 11, and the installation is completed. This process ensures the precise positioning and reliable connection of the main shaft 4.

[0033] Reference Figure 3 The circulation component includes a lubricating oil tank 9, the top of the lubricating oil tank 9 is fixedly connected to the bottom of the connecting block 2, a water pipe 2 5 is fixedly connected to the middle side of the top of the lubricating oil tank 9, a water pipe 3 is fixedly connected to the middle side of the outside of the lubricating oil tank 9, the upper outer side of the water pipe 3 is fixedly connected to the inside of the connecting block 1, a filter screen 10 is slidably connected to the inside of the lubricating oil tank 9, and two bolts 18 are threadedly connected to the outer side of the filter screen 10, a water pump 8 is arranged on the outer side of the lower part of the water pipe 3, and a water pump 23 is arranged on the outer side of the water pipe 25.

[0034] Specifically, during the operation of the two main shafts 4, the crucial lubrication link begins with opening valve 17 and starting the high-efficiency water pump 18. This force drives the lubricant in the lubricating oil tank 9 to be continuously injected into the connecting block 1 along the water pipe 25, providing necessary lubrication protection for the precision main shaft 4. After sufficient lubrication, the valve 22 is opened in time, and the lubricating oil returns to the lubricating oil tank 9 again under the action of the water pump 23. In this process, the filter 10 is like a protective barrier, filtering out impurities therein to ensure the purity of the lubricating oil, thereby realizing the efficient recycling of the lubricating oil, avoiding unnecessary loss of resources, and maintaining the excellent performance of the lubricating oil. When the filter 10 needs to be regularly maintained or replaced, the operator only needs to gently twist the bolt 18. As the bolt 18 rotates, it will gradually detach from the inside of the filter 10 until it is completely removed from the lubricating oil tank 9. This process is simple and safe, does not require special tools, and reflects the humanization of the design. The easy removal of the filter 10 provides great convenience for replacement and ensures the long-term stable operation and work efficiency of the system.

[0035] Reference Figure 2-Figure 4 , a plurality of support columns 6 are fixedly connected to the bottom of the connecting block 2, the left end of the spring 14 is fixedly connected to the inner wall of the plug-in block 15, the bottom end of the spring 16 is fixedly connected to the inner bottom wall of the fixed block 17, a slide groove 20 is provided inside the fixed block 17, a slide groove 19 is provided inside the plug-in block 15, the outer side of the water pipe 25 is fixedly connected to the inside of the connecting block 22, the outer sides of the two bolts 18 are both threadedly connected to the inside of the lubricating oil tank 9, the outer side of the middle part of the water pipe 3 is fixedly connected to the valve 7, and the outer side of the water pipe 25 is fixedly connected to the valve 22.

[0036] Specifically, the design of the connection block 2 is extremely stable, and its bottom is equipped with multiple support columns 6 to ensure stability under various working conditions. The spring 14 is cleverly embedded in the inner wall of the plug-in block 15, as an important part of the disassembly system, pushing the push rod 12 when needed. The spring 16 is fixed at the bottom of the fixed block 17, and the existence of its slide groove 20 makes the spring expansion and contraction smoother. The slide groove 19 inside the plug-in block 15 matches the spring 14, and they jointly participate in the installation and disassembly operations. The water pipe 25 is tightly fixed inside the connection block 22 to provide a channel for the lubrication system. The two bolts 18 are located inside the lubricating oil tank 9, and are connected by threads to ensure the stable installation and disassembly of the filter 10. In addition, a valve 7 is provided on the outside of the middle part of the water pipe 3 to control the flow of oil, and the outside of the water pipe 25 is connected to the valve 22, allowing the lubricating oil to return to the lubricating oil tank 9 after lubrication and be purified by the filter 10.

[0037] Working principle: When it is necessary to disassemble the two spindles 4, push the push rod 12 to move inside the fixed block 11, and then squeeze the baffle 13 to completely leave the fixed block 11, so that the spring 14 is compressed, and then squeeze the plug-in block 15 to move downward, and then compress the spring 2 16 until the plug-in block 15 leaves the plug-in block 15. At this time, the fixed block 11 can be opened to disassemble the two spindles 4. When it is necessary to install the two spindles 4, put the two spindles 4 on the connecting block 2, and close the connection by rotating the connection. Connecting block 1, at this time, it is necessary to press baffle 13, spring 2 16 will be compressed, so that baffle 21 moves upward, and plug-in block 15 moves upward until spring 14 recovers from the compressed state and pushes baffle 13 to be re-inserted into the interior of fixed block 11, and the installation is successful at this time. When the two main shafts 4 are working, open valve 17, start water pump 18 to drive the lubricating oil in lubricating oil tank 9 from water pipe 25 into connecting block 1 to lubricate main shaft 4, after lubrication, open valve 22, and the lubricating oil will pass through water pump 2. Under the action of 23, it will enter lubricating oil tank 9 from water pipe 25 again, and clean impurities through filter 10, at this time, it can be recycled without reducing the quality of lubricating oil, avoiding waste of resources, when it is necessary to disassemble filter 10, twist bolt 18, at this time bolt 18 rotates and will leave the inside of filter 10, until it completely leaves the inside of lubricating oil tank 9, at this time, filter 10 can be removed for replacement.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
