Technical Field
[0001] This utility model relates to the field of rolling mill technology, specifically a connection structure between a rolling mill and a rolling mill shaft. Background Technology
[0002] Rolling mills are tools that cause plastic deformation of metals. They are important consumable components that determine the efficiency of rolling mills and the quality of rolled products. Rolls are important parts on rolling mills in steel mills. They use the pressure generated by the rolling of a pair or a group of rolls to roll steel. They mainly bear the dynamic and static loads during rolling, as well as the effects of wear and temperature changes.
[0003] Chinese Utility Model Patent Publication No. CN222369948U discloses a connection structure between a roll and a roll shaft. The specification of this connection structure includes a positioning post that limits the rotation of the rotating plate on the threaded rod, preventing loose threads from affecting the use of the roll body and the roll shaft body. The positioning post is inserted into a positioning groove to limit the threaded rod, thus preventing loose threads. However, while this connection structure allows for the design of the threaded rod, it lacks a limiting structure between the roll and the roll shaft. This can easily lead to problems when the screw holes are not on the same horizontal plane, making subsequent fastening with fasteners difficult and resulting in poor practicality. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a connection structure between a roll and a roll shaft. It can effectively solve the problem in the prior art that although the threaded rod design can be realized, the limiting structure between the roll and the roll shaft is not designed. This easily leads to the problem that when the two are connected, the screw holes are not on the same horizontal plane, which makes it inconvenient to use fasteners for fixation and results in poor practicality.
[0005] The technical solution adopted by this utility model is: a connection structure between a roll and a roll shaft, including a roll body, a roll shaft assembly one, and a roll shaft assembly two. A slot one is provided at one end of the roll body near the roll shaft assembly one, and a slot two is provided at one end of the roll body near the roll shaft assembly two. A connecting flange one is fixedly installed at one end of the roll body near the roll shaft assembly one, and a connecting flange two and a connecting flange three are fixedly installed at one end of the roll body near the roll shaft assembly two. The roll body and the roll shaft assembly two are connected by an insertion joint. Limiting components are provided at the ends of the roll shaft assembly one and the roll shaft assembly two away from the roll body.
[0006] The first roll shaft assembly includes a first connecting roll shaft, a connecting plate is fixedly installed on the outer edge of the first connecting roll shaft, and a plug is fixedly installed on one end of the first connecting roll shaft near the roll body.
[0007] The second roll shaft assembly includes a second connecting roll shaft. A first limiting plate and a second limiting plate are fixedly installed on the outer edge of the second connecting roll shaft. A second insert post is fixedly installed at one end of the second connecting roll shaft near the roll body and is inserted into the slot second.
[0008] Preferably, a limiting groove is provided at one end of the roll body near the roll shaft assembly, and an insert is fixedly installed at the outer edge of the insert post. The limiting groove and the insert have a "T" shaped cross-section, and the limiting groove and the insert are installed by insertion.
[0009] Through the above technical solution, by combining the limiting groove and the insert bar, when the roll body and the roll shaft assembly are installed, the insert post can be inserted through the slot, and the insert bar can be inserted into the limiting groove. This not only enables the quick alignment of the roll body and the roll shaft assembly, but also prevents the roll body and the roll shaft assembly from rotating during subsequent fixing, thus reducing the difficulty of subsequent installation.
[0010] Preferably, a limiting post is fixedly installed at the end of the connecting disc away from the first connecting roller shaft, and is plugged into the connecting flange. Multiple limiting posts are provided, and the multiple limiting posts are distributed in a ring about the center line of the roller body.
[0011] Through the above technical solution, by designing the limiting post, when the limiting groove and the insert are installed, the limiting post can be inserted into the mounting hole of the connecting flange at the same time, which can achieve dual positioning and facilitate subsequent locking.
[0012] Preferably, a fixing post 1 is fixedly installed at one end of the limiting plate 1 near the roll body, and a fixing post 2 is fixedly installed at one end of the limiting plate 2. The diameter of the limiting plate 2 is larger than the diameter of the limiting plate 1. The diameter of the limiting plate 1 is the same as the diameter of the connecting flange 2. The diameter of the limiting plate 2 is the same as the diameter of the connecting flange 3. The fixing post 1 and the fixing post 2 are adapted to the connecting flange 2 and the connecting flange 3.
[0013] Through the above technical solution, by cooperating with the first and second limiting plates, when installing the second roll shaft assembly, the first and second limiting plates can engage with the second and third connecting flanges, while the first and second fixing posts can be inserted into the second and third connecting flanges, thus achieving the initial positioning of the roll body and the second roll shaft assembly, which facilitates subsequent locking.
[0014] Preferably, the limiting component includes a limiting cover, a threaded post, and a second anti-loosening retaining ring fixedly installed at the outer edge of the first and second roll shaft assemblies.
[0015] With the above technical solution, through the cooperation of the limiting cover and the threaded column, after the initial locking of the first and second roll shaft assemblies is completed, the threaded column can pass through the first and second roll shaft assemblies and extend into the first and third connecting flanges to achieve locking.
[0016] Preferably, an anti-loosening retaining ring one is fixedly installed at the outer edge of the threaded post, and a retaining tooth is fixedly installed at one end of the anti-loosening retaining ring one near the anti-loosening retaining ring two. A retaining groove is opened at one end of the anti-loosening retaining ring two near the anti-loosening retaining ring one, and the retaining tooth engages with the retaining groove.
[0017] Through the above technical solution, the design of anti-loosening retaining ring one and anti-loosening retaining ring two allows the retaining components to engage with the retaining teeth in the retaining groove when tightened, thus preventing them from easily loosening due to the movement of the roll body itself.
[0018] Preferably, the limiting components are provided in multiple identical sets, one set of the limiting components passes through the second roll shaft assembly and is threadedly connected to the third connecting flange, and another set of the limiting components passes through the first roll shaft assembly and is threadedly connected to the first roll shaft assembly.
[0019] The above technical solution, through the design of multiple limit components, can reduce the installation steps, and the use of multiple limit components can avoid the easy damage of a single limit component, thereby affecting its normal use.
[0020] Compared with the prior art, the present invention provides a connection structure between a roll and a roll shaft, which has the following advantages:
[0021] 1. The connection structure between the roll and the roll shaft, through the cooperation of the limiting groove and the insert bar, allows the insert bar to be inserted into the slot when the roll body and the roll shaft assembly are installed. At the same time, the insert bar can be inserted into the limiting groove. This enables the quick alignment of the roll body and the roll shaft assembly and also prevents the roll body and the roll shaft assembly from rotating during subsequent fixing, reducing the difficulty of subsequent installation. In addition, the design of the limiting post allows the limiting post to be inserted into the mounting hole of the connecting flange, which can achieve dual positioning and facilitate subsequent locking. This avoids the problem of not being able to use fasteners for fixing when the holes are not on the same horizontal plane during installation.
[0022] 2. The connection structure between the roll and the roll shaft, through the design of anti-loosening retaining ring one and anti-loosening retaining ring two, allows the retaining teeth to engage in the retaining groove when the limiting components are tightened, which can prevent the two from easily loosening due to the movement of the roll body itself. In addition, the design of multiple limiting components can reduce the installation steps, and the use of multiple limiting components can prevent the individual limiting components from being easily damaged, thereby improving their service life.

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.
[0032] Example 1: As Figure 1-7As shown, the present invention provides a connection structure between a roll and a roll shaft, including a roll body 1, a roll shaft assembly 1 5, and a roll shaft assembly 2 9. A slot 1 2 is provided at one end of the roll body 1 near the roll shaft assembly 1 5, and a slot 2 6 is provided at one end of the roll body 1 near the roll shaft assembly 2 9.

The roll body 1 and the roll shaft assembly 2 9 are connected by an insertion joint. A limit component 10 is provided at the end of the roll shaft assembly 1 5 and the roll shaft assembly 2 9 away from the roll body 1.
[0033] The roll shaft assembly 5 includes a first connecting roll shaft 501, a connecting plate 502 is fixedly installed on the outer edge of the first connecting roll shaft 501, and a plug 504 is fixedly installed on one end of the first connecting roll shaft 501 near the roll body 1.
[0034] The second roller shaft assembly 9 includes a second connecting roller shaft 901. A first limiting plate 902 and a second limiting plate 904 are fixedly installed on the outer edge of the second connecting roller shaft 901. A second insert post 906 that is inserted into the slot 6 is fixedly installed at one end of the second connecting roller shaft 901 near the roller body 1.
[0035] Specifically, a limiting groove 3 is provided at one end of the roll body 1 near the roll shaft assembly 5. An insert strip 505 is fixedly installed on the outer edge of the insert post 504. The limiting groove 3 and the insert strip 505 have a "T" shaped cross-section. The limiting groove 3 and the insert strip 505 are installed by insertion. The advantage is that, through the cooperation of the limiting groove 3 and the insert strip 505, when the roll body 1 is installed with the roll shaft assembly 5, the insert post 504 can be inserted through the slot 2, and at the same time, the insert strip 505 can be inserted into the limiting groove 3. This can achieve quick alignment between the roll body 1 and the roll shaft assembly 5, and at the same time, it can prevent the roll body 1 and the roll shaft assembly 5 from easily rotating during subsequent fixing, reducing the difficulty of subsequent installation.
[0036] Specifically, a limiting post 503 is fixedly installed at the end of the connecting plate 502 away from the first connecting roller shaft 501, which is inserted into the connecting flange 4. Multiple limiting posts 503 are provided, and the multiple limiting posts 503 are distributed in a ring about the center line of the roll body 1. The advantage is that, through the design of the limiting post 503, when the limiting groove 3 and the insert bar 505 are installed, the limiting post 503 can be inserted into the mounting hole of the connecting flange 4 at the same time, which can achieve dual positioning and facilitate subsequent locking.
[0037] Specifically, a fixing post 903 is fixedly installed at one end of the limiting plate 1 near the roll body 1, and a fixing post 905 is fixedly installed at one end of the limiting plate 2 904.

The fixing posts 1 903 and 2 905 are compatible with the connecting flange 2 7 and the connecting flange 3 8. The advantage is that, through the cooperation of the limiting plate 1 902 and the limiting plate 2 904, when installing the roll shaft assembly 2 9, the initial positioning of the roll body 1 and the roll shaft assembly 2 9 can be achieved through the snap-fit cooperation between the limiting plate 1 902 and the limiting plate 2 904 and the connecting flange 2 7 and the connecting flange 3 8, while the fixing posts 1 903 and 2 905 are snapped into the connecting flange 2 7 and the connecting flange 3 8, which facilitates subsequent locking.
[0038] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.
[0039] Specifically, the limiting component 10 includes a limiting cover 1001, a threaded post 1002, and an anti-loosening retaining ring 1005 fixedly installed at the outer edge of the first roll shaft assembly 5 and the second roll shaft assembly 9. The advantage is that, through the cooperation of the limiting cover 1001 and the threaded post 1002, after the first roll shaft assembly 5 and the second roll shaft assembly 9 are initially locked, the threaded post 1002 can pass through the first roll shaft assembly 5 and the second roll shaft assembly 9 and extend into the first connecting flange 4 and the third connecting flange 8 to achieve locking.
[0040] Specifically, an anti-loosening retaining ring 1003 is fixedly installed on the outer edge of the threaded post 1002. A retaining tooth 1004 is fixedly installed on the end of the anti-loosening retaining ring 1003 near the end of the anti-loosening retaining ring 1005. A retaining groove 1006 is opened on the end of the anti-loosening retaining ring 1005 near the end of the anti-loosening retaining ring 1003. The retaining tooth 1004 engages with the retaining groove 1006. The advantage is that, through the design of the anti-loosening retaining ring 1003 and the anti-loosening retaining ring 1005, the retaining tooth 1004 can be engaged in the retaining groove 1006 when the limiting component 10 is tightened, which can prevent the two from loosening easily due to the movement of the roller body 1 itself.
[0041] Specifically, the limit components 10 are provided in multiple sets. One set of limit components 10 passes through the second roll shaft assembly 9 and is threadedly connected to the third connecting flange 8. Another set of limit components 10 passes through the first roll shaft assembly 5 and is threadedly connected to the first roll shaft assembly 5. The advantage is that by designing multiple limit components 10, the installation steps can be reduced. Furthermore, by using multiple limit components 10, it is possible to avoid damage to a single limit component 10, which would affect its normal use.
[0042] Working Principle: During use, through the cooperation of the limiting groove 3 and the insert 505, when the roll body 1 and the roll shaft assembly 5 are installed, the insert 504 can be inserted through the slot 2, and the insert 505 can be inserted into the limiting groove 3. This achieves quick alignment of the roll body 1 and the roll shaft assembly 5, and also prevents the roll body 1 and the roll shaft assembly 5 from rotating during subsequent fixing, reducing the difficulty of subsequent installation. Through the design of the limiting post 503, when the limiting groove 3 and the insert 505 are installed, the limiting post 503 can be inserted into the mounting hole of the connecting flange 4 at the same time, achieving double positioning and facilitating subsequent locking. Through the cooperation of the limiting plate 902 and the limiting plate 904, when the roll shaft assembly 9 is installed, the locking cooperation between the limiting plate 902 and the connecting flange 7 and the connecting flange 8 can simultaneously fix the insert 504 and the connecting flange 7. The fixing post 2 905 is inserted into the connecting flange 2 7 and the connecting flange 3 8 to achieve initial positioning of the roll body 1 and the roll shaft assembly 2 9, which facilitates subsequent locking. Through the cooperation of the limiting cover 1001 and the threaded post 1002, after the roll shaft assembly 1 5 and the roll shaft assembly 2 9 are initially locked, the threaded post 1002 can pass through the roll shaft assembly 1 5 and the roll shaft assembly 2 9 and extend into the connecting flange 1 4 and the connecting flange 3 8 to achieve locking. Through the design of the anti-loosening retaining ring 1 1003 and the anti-loosening retaining ring 2 1005, the retaining teeth 1004 can be engaged in the retaining groove 1006 when the limiting component 10 is tightened, which can prevent the two from loosening easily due to the movement of the roll body 1 itself. The design of multiple limiting components 10 can reduce the installation steps, and the use of multiple limiting components 10 can prevent the individual limiting component 10 from being easily damaged, thus affecting its normal use.
