[0002] A rolling mill is a device that realizes the metal rolling process. It generally refers to the equipment that completes the entire process of rolling production. According to the number of rollers, rolling mills can be divided into two-roller, four-roller, six-roller, eight-roller, twelve-roller, eighteen-roller, etc.; according to the arrangement of rollers, they can be divided into "L" type, "T" type, "F" type, "Z" type and "S" type. In order to ensure the normal rotation of the rollers on the rolling mill when the rolling mill is working, it is necessary to connect the universal joint shaft to the rollers with the help of shaft sleeves on the rolling mill side.

[0003] The current rolling mill side shaft sleeve is mainly composed of an integrated sleeve body, a mounting hole opened in the universal connection part of the sleeve body, and a fixing bolt for mounting the sleeve body roll connection part. Although the rolling mill side shaft sleeve of the above structure can realize the connection transmission between the universal connection shaft and the roll on the rolling mill when in use, since the sleeve body and the roll are connected mainly by manually screwing the bolts one by one to achieve the limitation of the sleeve body and the roll shaft, the operation process is relatively cumbersome, which not only increases the labor intensity of the staff, but also makes the connection and fixing efficiency of the sleeve body and the roll relatively low, which is not convenient for the efficient use of the sleeve body.

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] like Figure 1-Figure 3As shown, a rolling mill side sleeve structure in this embodiment includes a sleeve body 1, the sleeve body 1 includes a universal connection part 101 connected to the universal connection shaft on the rolling mill and a roller connection part 102 formed at one end of the universal connection part 101, wherein a threaded part 6 is installed on the outer side of the roller connection part 102, a sliding sleeve 5 is installed on the roller connection part 102 at the threaded part 6, a spiral ring 13 is formed on one side of the sliding sleeve 5, and a conical groove 7 is opened on the side of the sliding sleeve 5 facing away from the spiral ring 13, and two rows of receiving grooves 3 are opened in an annular shape on one side of the sliding sleeve 5 on the roller connection part 102, and a conical pressure block 2 is installed in each receiving groove 3, and the upper side of the conical pressure block 2 is a conical structure. The taper is the same as that of the conical groove 7. When the sliding sleeve 5 moves to the conical pressure block 2, the conical pressure block 2 can be moved downward by sliding in contact with the conical surface, so that the limit rod 9 can be inserted into the roller shaft on the rolling mill roller. The conical pressure block 2 is installed with a limit rod 9 on the side facing the receiving groove 3. A spring 8 is installed on the outside of the limit rod 9. A sliding hole 10 for the limit rod 9 to pass through is opened at the bottom end of the spring 8 in the receiving groove 3. Four levers 4 are also installed in a ring shape on the outside of the sliding sleeve 5. A gap is reserved between the part of the sliding sleeve 5 located between the spiral ring 13 and the conical groove 7 and the outer wall of the roller connecting part 102, so that the conical pressure block 2 can be easily moved downward after the conical groove 7 contacts the straight surface on the conical pressure block 2.

[0030] like Figure 1-Figure 3 As shown, in this embodiment, a mounting hole 12 is further provided in the universal connection part 101, and a slot 11 is provided at the place where the roller connection part 102 is connected to the roller on the rolling mill. The mounting hole 12 is mainly cooperated with the external screw and the nut to realize the connection between the sleeve body 1 and the universal connection shaft on the rolling mill. The roller connection part 102 is also mainly used to realize the connection between the sleeve body 1 and the bearing seat on the rolling mill. The threaded part 6 is formed on the roller connection part 102, and the screw ring 13 is screwed to the threaded part 6. The cooperation between the screw ring 13 and the threaded part 6 can realize the convenient rotation and sliding of the sleeve 5 relative to the roller connection part 102.

[0031] like Figure 1-Figure 3 As shown, in this embodiment, the limit rod 9 is welded to the conical pressure block 2, and the limit rod 9 passes through the spring 8. The limit rod 9 is mainly matched with the mounting hole pre-opened on the roller shaft, so as to realize the convenient connection and fixation between the roller and the sleeve body 1. The top end of the spring 8 is welded to the conical pressure block 2, and the bottom end of the spring 8 is welded to the receiving groove 3. The spring 8 is mainly used to realize the automatic lifting and resetting of the conical pressure block 2 after the sliding sleeve 5 slides.

[0032] The specific implementation process of this embodiment is as follows: when in use, after the roller shaft is inserted into the sleeve body 1, the sleeve 5 is first rotated by rotating the lever 4, so that the sleeve 5 can slide along the roller connecting portion 102 under the action of the threaded transmission. During the sliding of the sleeve 5 along the roller connecting portion 102, the conical groove 7 squeezes the upper side of the conical pressure block 2, which will cause the conical pressure block 2 to move into the receiving groove 3. After the conical pressure block 2 enters the receiving groove 3, the limiting rod 9 will be inserted into the limiting hole pre-opened on the roller shaft, thereby realizing the quick connection and fixation of the sleeve body 1 and the roller. Because the above-mentioned installation method eliminates the tedious operation of manually tightening the bolts one by one, it not only saves manpower but also improves the connection and fixation efficiency of the sleeve body 1 and the roller.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
