Description

Technical Field

[0001] The present invention relates to the technical field of mechanical seal assembly, and particularly to an automatic assembly process and equipment for mechanical seals. Background Technique

[0002] Mechanical seals belong to one of the precision and relatively complex mechanical basic components, and are key components of various equipment such as pumps, reaction synthesis kettles, turbine compressors, and submersible motors. Gasket seals, packing seals, mechanical seals, non-contact seals, and injection-type pressure plugging are common sealing forms. Among them, packing seals should be the most common, and it also includes soft packing seals, hard packing seals, and molded packing seals. Among them, rubber sealing rings are the most representative and commonly used mechanical seals.

[0003] Currently, when putting a rubber sealing ring on the outside of a specified pipe body of a mechanical device, the caliber of the rubber sealing ring is often manually enlarged and then put on the outside of the specified pipe body. However, for some rubber sealing rings with greater toughness, the installation work of the installer will be very time-consuming and laborious; and during the installation process, the position of the rubber sealing ring cannot be automatically aligned, and manual adjustment of the position of the rubber sealing ring on the outside of the pipe body is often required, making it impossible for the operator to quickly and accurately put the rubber sealing ring on the corresponding position outside the specified pipe body of the machine, thus reducing the use effect of the mechanical seal assembly equipment; at the same time, when installing the rubber sealing ring into the groove inside the specified pipe body of the mechanical device, currently, a corresponding sealing ring holder is still needed to bend and deform it before it can be sent into the inner groove of the specified pipe body. However, since the distance between the three groups of struts of the existing sealing ring holder is often fixed, it cannot be applied to rubber sealing rings of different calibers.

[0018] Compared with the prior art, the present invention provides a mechanical seal automatic assembly process and equipment, which has the following beneficial effects:

[0019] 1. After the rubber sealing ring is sleeved on the outer sides of the eight arc-shaped plates, the present invention controls the first driving device to drive the rotating pipe to rotate clockwise, so that the sliding blocks on the sliding rods gradually move away from the fixed ring. At this time, the eight arc-shaped plates will synchronously move away from the center position of the circular plate, thereby enlarging the diameter of the rubber sealing ring. Then, it is sleeved on the outer side of the designated pipe body of the mechanical equipment. Next, the eight arc-shaped plates are controlled to move towards the center position of the circular plate, so that the diameter of the rubber sealing ring gradually returns. Then, it is pushed away from the outer sides of the eight arc-shaped plates, and the rubber sealing ring will automatically and tightly sleeve on the outer side of the designated pipe body of the mechanical equipment. In the whole process, there is no need for manual effort to enlarge it, which saves time and effort, reduces the installation difficulty of the installers, and also enables the equipment to enlarge rubber sealing rings of different diameters. And during the process of the rubber sealing ring being stretched to enlarge its diameter by itself, the force on each part is relatively uniform, avoiding a certain part of the rubber sealing ring from being over-stretched and losing its elastic recovery ability.

[0020] 2. After the present invention enlarges the diameter of the rubber sealing ring through the eight arc-shaped plates, all four first support columns are inserted into the inner side of the designated pipe body of the mechanical equipment. Then, the second driving device is controlled to drive the rotating rod to rotate clockwise, so that the second internal thread ring on the first lead screw gradually moves away from the center position of the circular plate until all four first support columns abut against the inner side of the designated pipe body of the mechanical equipment. At this time, the whole assembly equipment will be facing the pipe body, and the distances between different parts on the inner side of the rubber sealing ring outside the arc-shaped plate and the outer side of the pipe body are the same. Then, during the process of controlling the diameter of the rubber sealing ring to recover, the rubber sealing ring can accurately stay at the designated position on the outer side of the pipe body, which helps the rubber sealing ring to accurately sleeve on the corresponding position on the outer side of the pipe body after leaving the outer side of the arc-shaped plate, avoiding the need to manually adjust the position of the rubber sealing ring subsequently, and greatly improving the use effect of the whole assembly equipment.

[0021] 3. When the rubber sealing ring is installed into the inner groove of the pipe body, the rubber sealing ring is placed flat on the table. Then, two first support columns on one side of the transmission gear are inserted into the inner side of the rubber sealing ring, while the other two first support columns are located outside the rubber sealing ring, and the second support column is also located outside the rubber sealing ring. Then, the sleeve is manually rotated to make the second support column approach the two first support columns located inside the inner ring of the rubber sealing ring. At this time, these two first support columns and the second support column will function like a sealing ring holder, squeezing and bending the rubber sealing ring to deform it, so that the rubber sealing ring at this time presents a "U"-shaped structural shape, thereby facilitating the bent and deformed rubber sealing ring to be sent into the inner side of the pipe body and installed into the inner groove of the pipe body. And since the positions of the first support columns can be adjusted and changed, the two first support columns cooperating with the second support column can bend and deform rubber sealing rings of different diameters, thus improving the applicable range of the whole assembly equipment.

[0042] Furthermore, first bearings are symmetrically installed at both ends of the outer side of the rotating rod 207, and the outer rings of the two sets of first bearings are fixedly connected to the inner wall of the fixing ring 9 and the inner wall of the power compartment 7 respectively, which helps to improve the stability of the rotating rod 207 during the rotation process.

[0043] Furthermore, second bearings are symmetrically installed at both ends of the outer side of the second screw rod 305, and the outer rings of the two sets of second bearings are fixedly connected to the inner wall of the main bin 6, which helps to ensure the stability of the second screw rod 305 during rotation.

[0048] Embodiment 1, as Figures 1-5 and Figures 7-11 As shown, after the caliber of the rubber sealing ring is expanded by eight groups of arc plates 5, the four groups of first support columns 204 are all inserted into the inner side of the designated tube body of the mechanical equipment, and then the second driving device 208 is controlled to drive the rotating rod 207 to rotate clockwise. The rotating rod 207 drives the four groups of first screw rods 201 to rotate synchronously through the transmission of the active bevel gear 206 and the driven bevel gear 205. The second internal thread ring 202 on the first screw rod 201 is gradually moved away from the center position of the circular plate 1 by the thread effect, and the first support column 204 on the second internal thread ring 202 will also move synchronously and slide inside the second strip hole 203. The cooperation between the second strip hole 203 and the first support column 204 can allow the second internal thread ring 202 to move stably until the four groups of first support columns 204 are all against the inner side of the designated tube body of the mechanical equipment. At this time, the entire assembly equipment will be facing the tube body. In the process of controlling the caliber of the rubber sealing ring to recover, the rubber sealing ring can accurately stay at the designated position outside the tube body.

[0049] Embodiment 2, as Figures 1-11As shown in the figure, place the rubber sealing ring flat on the tabletop. Then, insert the two groups of first support columns 204 on one side of the transmission gear 306 into the inner side of the rubber sealing ring, while the other two groups of first support columns 204 are located on the outer side of the rubber sealing ring, and the second support column 304 is also located on the outer side of the rubber sealing ring. Then, manually rotate the sleeve 301, and the sliding ring 15 slides inside the annular chute 16. The transmission between the annular rack 307 and the transmission gear 306 can drive the second lead screw 305 to rotate clockwise. Using the thread action, the third internal thread ring 303 is forced to stably move from the position of the first group of transmission gears 306 to the position of the second group of transmission gears 306. The second support column 304 slides inside the third strip-shaped hole 302, making the second support column 304 approach the two first support columns 204 located inside the inner ring of the rubber sealing ring. At this time, these two first support columns 204 and the second support column 304 will function like a sealing ring clamp, squeezing and deforming the rubber sealing ring, making the rubber sealing ring present a "U"-shaped structure at this time, so as to facilitate the deformed rubber sealing ring to be sent into the inner side of the pipe body and installed in the groove on the inner side of the pipe body.

[0050] Working principle: Before use, connect the device to the power supply. Then, put the rubber sealing ring on the outside of the eight arc-shaped plates 5, and control the first driving device 19 to drive the rotating pipe 12 to rotate clockwise through the control panel 18. Using the thread action, the first internal thread ring 13 is forced to gradually move towards the direction of the circular plate 1 on the outside of the rotating pipe 12. During this process, the sliding block 10 on the sliding rod 11 gradually moves away from the fixed ring 9. At this time, the eight arc-shaped plates 5 will synchronously move away from the center position of the circular plate 1, expanding the diameter of the rubber sealing ring. Then, put it on the outside of the specified pipe body of the mechanical equipment, and then control the eight arc-shaped plates 5 to move towards the center position of the circular plate 1, making the diameter of the rubber sealing ring gradually recover until the inner sides of the eight arc-shaped plates 5 are all attached to the outside of the pipe body. Then, push the rubber sealing ring away from the outside of the eight arc-shaped plates 5. After the rubber sealing ring leaves the outside of the eight arc-shaped plates 5, it will automatically tightly fit on the outside of the specified pipe body of the mechanical equipment.
