[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 , Figure 2 As shown, a roller assembly of a stainless steel pipe rolling machine includes a roller shaft 4, a plug block 5 is fixedly connected to the right side of the roller shaft 4, a side mounting assembly 1 is plugged into the right side of the plug block 5, a base assembly 2 is fixedly connected to the bottom of the side mounting assembly 1, and a clamp assembly 3 is threadedly connected to the left side of the base assembly 2.

[0027] The base assembly 2 assists the side mounting assembly 1 and the clamp assembly 3 to be stably installed at a predetermined position, and the clamp assembly 3 and the side mounting assembly 1 assist the installation of the roller shaft 4 and the insert block 5 .

[0028] like Figure 2 , Figure 3 As shown, the side mounting assembly 1 includes a side panel 11, the bottom of the side panel 11 is fixedly connected to the top right side of the base assembly 2, the inner wall of the side panel 11 is rotatably connected to a rotating shaft 12, a slot 13 is provided on the left side of the rotating shaft 12, the inner wall of the slot 13 is plugged into the surface of the plug block 5, and the base assembly 2 includes a base plate 21, the top right side of the base plate 21 is fixedly connected to the bottom of the side panel 11, and a slide groove 22 is provided on the top left side of the base plate 21.

[0029] By placing the left side shaft of the roller shaft 4 in the grooves of the two clamping blocks 31 and then plugging the plug block 5 fixedly connected to the right side of the roller shaft 4 into the slot 13, the movable installation of the roller shaft 4 is achieved, so that the rotating shaft 12 rotatably connected to the inner wall of the side plate 11 assists in the installation of the roller shaft 4.

[0030] like Figure 4 , Figure 5As shown, the inner wall of the slide groove 22 is rotatably connected to a threaded shaft 26, the front of the threaded shaft 26 is fixedly connected to a hand crank 27 and the hand crank 27 is located in front of the base plate 21, the top of the base plate 21 is rectangular and rotatably connected to four threaded shafts 23, the outer surfaces of the four threaded shafts 23 are threadedly connected to a rolling block plate 24, a groove 25 is provided in the middle of the top of the rolling block plate 24, the inner wall of the groove 25 overlaps the surface of the roller shaft 4, the clamp assembly 3 includes two clamping blocks 31, the bottoms of the two clamping blocks 31 are fixedly connected to push blocks 32, and the inner walls of the two push blocks 32 are threadedly connected to the outer surfaces of the threaded shaft 26.

[0031] When the stainless steel pipe moves through the groove 25, the four threaded shafts 1 23 connected in a rectangular shape and rotatably connected at the top of the base plate 21 are used to rotate and adjust, and the distance between the rolling block plate 24 and the roller shaft 4 is adjusted by the threads, so as to better assist the stainless steel pipe rolling machine in controlling the stainless steel pipe, thereby not hindering the rotation of the roller shaft 4 and the rotating shaft 12 to assist the movement of the stainless steel pipe. At the same time, the slide groove 22 opened on the left side of the top of the base plate 21 is used to assist the installation of the threaded shaft 26. The manual clockwise rotation of the hand crank 27 drives the rotation of the threaded shaft 26, thereby the threads drive the two clamping blocks 31 to move closer to each other. When they rotate counterclockwise, the two clamping blocks 31 move away from each other, thereby better facilitating the maintenance and replacement of the installation of the roller shaft 4.

[0032] like Figure 5 As shown, the arc grooves on the opposite surfaces of the two clamping blocks 31 are fixedly connected with wear-resistant blocks 33 , and the surface of the wear-resistant blocks 33 is rotatably connected to the left outer surface of the roller shaft 4 .

[0033] The roller shaft 4 is driven to rotate when the stainless steel pipe moves through the groove 25 , and the wear-resistant blocks 33 fixedly connected to the arc grooves on the opposite surfaces of the two clamping blocks 31 play a role in wear-resistant reinforcement.

[0034] The working principle of the utility model is as follows: by placing the left side shaft body of the roller shaft 4 in the grooves of the two clamping blocks 31, and then using the plug block 5 fixedly connected to the right side of the roller shaft 4 to plug into the slot 13, the movable installation of the roller shaft 4 is realized. When the stainless steel pipe moves through the groove 25, the four threaded shafts 1 23 connected in a rectangular rotation at the top of the base plate 21 are used to rotate and adjust, and the distance between the rolling block plate 24 and the roller shaft 4 is adjusted by the thread, so as to better assist the stainless steel pipe rolling machine to control the stainless steel pipe, thereby not hindering the rotation of the roller shaft 4 and the rotating shaft 12 to assist the movement of the stainless steel pipe. At the same time, the slide groove 22 opened on the left side of the top of the base plate 21 is used to assist the installation of the threaded shaft 26, and the manual clockwise rotation of the hand crank 27 drives the rotation of the threaded shaft 26, so that the thread drives the two clamping blocks 31 to move close to each other, and rotate counterclockwise, so that the two clamping blocks 31 can move away from each other, thereby better repairing and replacing the installation of the roller shaft 4.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
