Description
Technical Field
[0001] This utility model belongs to the field of alloy cast iron roll technology, and in particular relates to an alloy cast iron roll cleaning device. Background Technology
[0002] Alloy cast iron rolls are a type of roll widely used in the steel metallurgical industry due to their excellent wear resistance, thermal crack resistance, and high strength. They are mainly used in the rolling process of various steel rolling mills to meet the plastic deformation requirements of steel. During use, alloy cast iron rolls accumulate various contaminants, such as oil, iron filings, and oxides. These contaminants affect the surface quality of the rolls. Therefore, cleaning alloy cast iron rolls is an important step to ensure their normal operation and extend their service life. Tools such as grinding wheels, sanding belts, or grinding heads are usually used to remove contaminants and defects from the roll surface through physical friction. By grinding and cleaning, these impurities can be effectively removed, restoring the metallic luster and smoothness of the roll surface, thereby improving the quality of rolled products.
[0003] The problem with the existing technology is that if no positioning measures are taken when grinding and cleaning alloy cast iron rolls, the rolls may shift or rotate during the grinding and cleaning process, causing the grinding belt to fail to make stable contact with the roll surface, thus affecting the cleaning effect of the rolls. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides an alloy cast iron roll cleaning device, which has the advantage of positioning the roll before controlling it for grinding and cleaning, thus preventing the roll from shifting. This solves the problem that if the existing alloy cast iron rolls are not positioned during grinding and cleaning, the rolls may shift or rotate during the grinding and cleaning process, causing the grinding belt to fail to make stable contact with the roll surface, thus affecting the cleaning effect of the roll.
[0005] This utility model is implemented as follows: an alloy cast iron roll cleaning device includes a base, a main body, a fixed-rotation assembly, a fixing structure, and a locking structure. A working arm is fixedly connected to the rear side of the top of the base. A push cylinder is fixedly connected to the top of the working arm. A grinding machine is fixedly connected to the output end of the push cylinder. Support arms are fixedly connected to the left and right sides of the top of the base, respectively. The main body is located on the side of the two support arms that are close to each other. A fixed-rotation assembly is located on the top of each of the two support arms. The fixed-rotation assembly includes two fixing rings. The outer surfaces of the two fixing rings are rotatably connected to the top of the support arm. The rear ends of the two fixing rings are rotatably connected via rotating shafts. Fixing rods are fixedly connected to the side of the two fixing rings away from the main body. Fixing handles are sleeved on the ends of the two fixing rods away from the fixing rings. The inner wall of the fixed ring is provided with a fixing structure, which includes an active plate and a passive plate. The rear ends of the active plate and the passive plate are rotatably connected by a rotating shaft. Rubber rings are fixedly connected to the inner walls of the active plate and the passive plate on their respective sides. The inner walls of the two rubber rings are respectively attached to one end of the main body. A positioning block is fixedly connected to the bottom of the front of the active plate. A positioning groove is opened at the bottom of the positioning block. The bottom of the passive plate is fixedly connected to the inner wall of the bottom fixed ring. A connecting groove is opened on the inner wall of the passive plate. An opening is opened at the top of the front of the passive plate. A horizontal groove is opened at the bottom of the passive plate. The positioning block is inserted into the inner wall of the opening. The connecting groove is connected to the opening and the horizontal groove respectively. Horizontal rods are fixedly connected to the left and right sides of the inner wall of the connecting groove. A locking structure is provided on the inner wall of the connecting groove.
[0006] In a preferred embodiment of this invention, the locking structure includes a movable slider, which is disposed at the bottom of the driven plate. The outer surface of the movable slider is slidably connected to the inner wall of the horizontal groove. A driven member is fixedly connected to the bottom of the movable slider, and a movable sliding arm is fixedly connected to the top of the movable slider. By setting the movable slider, when the driven member is pushed backward, it can drive the movable slider to slide backward in the horizontal groove, thereby driving the movement of the movable sliding arm.
[0007] In a preferred embodiment of this invention, the movable sliding arm is disposed on the inner wall of the connecting groove, the bottom of the movable sliding arm is fixedly connected to the top of the movable sliding block, and movable sliding rods are fixedly connected to the left and right ends of the top of the movable sliding arm, respectively. Active arms are respectively sleeved on the outer surfaces of the two movable sliding rods. By setting the movable sliding arm, the movable sliding arm can be driven by the passive sliding block to move backward in the connecting groove, synchronously driving the movement of the two movable sliding rods. Thus, the movement of the two movable sliding rods simultaneously drives the two active arms to rotate.
[0008] In a preferred embodiment of this invention, the two active arms are respectively disposed on the inner walls of the connecting groove. The ends of the two active arms that are far apart from each other are rotatably connected to the inner walls of the connecting groove via rotating shafts. Active grooves are respectively formed on the surfaces of the ends of the two active arms that are close to each other. The ends of the inner walls of the two active grooves that are far apart from each other are respectively in contact with the outer surfaces of the two movable sliding rods. Push arms are respectively fixedly connected to the ends of the two active arms that are far apart from each other. By setting the active arms, the two movable sliding rods squeeze the two active grooves while moving, thereby driving the two active arms to rotate relative to each other. In this way, when the two active arms rotate, they can respectively drive the two push arms to rotate in the same direction.
[0009] In a preferred embodiment of this invention, the back sides of the two push arms are fixedly connected to the front sides of the two active arms at opposite ends. The tops of the two push arms are each provided with an opening, and the sides of the two push arms that are close to each other are each provided with a stop arm. By providing the push arms, the two push arms can be offset from the horizontal bar through the openings during rotation, and push the two stop arms respectively, so that the two stop arms are subjected to force and move closer together.
[0010] In a preferred embodiment of this invention, the two stop arms are slidably connected to the outer surface of the horizontal rod at their respective rear ends. The sides of the two stop arms that are far apart from each other are respectively attached to the two push arms. The sides of the two stop arms that are close to each other are fixedly connected to a stop spring. The stop spring is sleeved on the outer surface of the horizontal rod. The top of the two stop arms is fixedly connected to a stop block. By setting the stop arms, the two stop arms are pushed by the push arms and slide close to each other on the surface of the horizontal rod, compressing the stop spring. The sliding of the two stop arms then drives the two stop blocks to move closer to each other.
[0011] As a preferred embodiment of this utility model, the two stop blocks are respectively fixedly connected to the top of the two stop arms on opposite sides. The opposite ends of the two stop blocks are respectively inserted into the inner wall of the positioning groove. By setting the stop blocks, the two stop blocks can be disengaged from the positioning groove when they move closer together, thereby releasing the fixation of the positioning blocks and thus releasing the fixed connection between the active plate and the passive plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, by setting up a base, main body, fixed rotation component, fixing structure and locking structure, achieves the effect of solving the problem that when existing alloy cast iron rolls are ground and cleaned, if no positioning measures are taken, the rolls may shift or rotate during the grinding and cleaning process, resulting in the grinding belt not being able to stably contact the roll surface, thus affecting the cleaning effect of the rolls.
[0014] 2. This utility model, by setting up a main body and a fixed-rotation component, enables the fixed structure and the locking structure to work together. The locking structure fixes the active plate and the passive plate, allowing them to clamp and position the two ends of the main body roller with rubber rings. Then, the roller is ground and cleaned by a grinding machine. The positioning measures for the roller ensure that the roller remains fixed during the grinding and cleaning process, thus guaranteeing the cleaning effect of the roller. Attached Figure Description

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0022] like Figures 1 to 4As shown in the figure, the alloy cast iron roll cleaning device provided by this utility model includes a base 1, a main body 2, a fixed rotation assembly 3, a fixing structure 4, and a locking structure 5. A working arm 101 is fixedly connected to the rear side of the top of the base 1. A push cylinder 102 is fixedly connected to the top of the working arm 101. A grinder 103 is fixedly connected to the output end of the push cylinder 102. Support arms 104 are fixedly connected to the left and right sides of the top of the base 1, respectively. The main body 2 is provided on the side of the two support arms 104 that is close to each other. The fixed rotation assembly 3 is provided on the top of the two support arms 104, and the fixed rotation assembly 3 includes two fixing rings 301. The outer surfaces of the two fixing rings 301 are rotatably connected to the top of the support arms 104, and the rear ends of the two fixing rings 301 are rotatably connected by rotating shafts. Fixing rods 302 are fixedly connected to the side of the two fixing rings 301 away from the main body 2, and fixing handles 30 are sleeved on the ends of the two fixing rods 302 away from the fixing rings 301. 3. The inner walls of the two fixed rings 301 are provided with a fixing structure 4. The fixing structure 4 includes an active plate 6 and a passive plate 7. The rear ends of the active plate 6 and the passive plate 7 are rotatably connected by a rotating shaft. Rubber rings 401 are fixedly connected to the inner walls of the active plate 6 and the passive plate 7 respectively on the side close to each other. The inner walls of the two rubber rings 401 are respectively attached to one end of the main body 2. A positioning block 601 is fixedly connected to the bottom of the front of the active plate 6. A positioning groove 602 is opened at the bottom of the positioning block 601. The bottom of the passive plate 7 is fixedly connected to the inner wall of the bottom fixed ring 301. A connecting groove 8 is opened on the inner wall of the passive plate 7. An opening 701 is opened at the top of the front of the passive plate 7. A horizontal groove 702 is opened at the bottom of the passive plate 7. The positioning block 601 is inserted into the inner wall of the opening 701. The connecting groove 8 is connected to the opening 701 and the horizontal groove 702 respectively. Horizontal rods 801 are fixedly connected to the left and right sides of the inner wall of the connecting groove 8. A locking structure 5 is provided on the inner wall of the connecting groove 8.
[0023] refer to Figure 3 and Figure 4 The locking structure 5 includes a movable slider 9, which is disposed at the bottom of the driven plate 7. The outer surface of the movable slider 9 is slidably connected to the inner wall of the horizontal groove 702. The bottom of the movable slider 9 is fixedly connected to the driven member 10, and the top of the movable slider 9 is fixedly connected to the movable sliding arm 11.
[0024] The above solution is adopted: by setting the movable slider 9, when the driven member 10 is pushed backward, it can drive the movable slider 9 to slide backward in the horizontal groove 702, and the sliding movable slider 9 can drive the movable sliding arm 11 to move.
[0025] refer to Figure 4 The movable sliding arm 11 is disposed on the inner wall of the connecting groove 8. The bottom of the movable sliding arm 11 is fixedly connected to the top of the movable sliding block 9. Movable sliding rods 12 are fixedly connected to the left and right ends of the top of the movable sliding arm 11, and active arms 13 are respectively sleeved on the outer surfaces of the two movable sliding rods 12.
[0026] The above scheme is adopted: by setting the movable sliding arm 11, the movable sliding arm 11 can be driven by the passive slider 9 to move backward in the connecting groove 8, and simultaneously drive the two movable sliding rods 12 to move. Thus, the movement of the two movable sliding rods 12 simultaneously drives the two active arms 13 to rotate.
[0027] refer to Figure 4 Two active arms 13 are respectively positioned on the inner wall of the connecting groove 8. The ends of the two active arms 13 that are far apart from each other are rotatably connected to the inner wall of the connecting groove 8 through a rotating shaft. Active grooves 14 are respectively opened on the surfaces of the ends of the two active arms 13 that are close to each other. The ends of the inner walls of the two active grooves 14 that are far apart from each other are respectively attached to the outer surfaces of the two movable sliding rods 12. Push arms 15 are respectively fixedly connected to the ends of the two active arms 13 that are far apart from each other.
[0028] The above scheme is adopted: by setting an active arm 13, the two movable slide rods 12 squeeze the two active grooves 14 while moving, thereby driving the two active arms 13 to rotate relative to each other. In this way, when the two active arms 13 rotate, they can respectively drive the two push arms 15 to rotate.
[0029] refer to Figure 4 The back of the two push arms 15 are fixedly connected to the front of the two active arms 13 at opposite ends. The top of the two push arms 15 is provided with an opening 16, and the two push arms 15 are provided with a stop arm 17 on the side that is close to each other.
[0030] The above solution is adopted: by setting the push arm 15, the two push arms 15 can be offset from the horizontal bar 801 through the through port 16 during rotation, and push the two stop arms 17 respectively, so that the two stop arms 17 are subjected to force and move closer together.
[0031] refer to Figure 4 The two stop arms 17 are slidably connected to the outer surface of the horizontal rod 801 at the middle of their rear ends. The two stop arms 17 are respectively attached to the two push arms 15 on the side that is far apart from each other. The two stop arms 17 are fixedly connected to the stop spring 18 on the side that is close to each other. The stop spring 18 is sleeved on the outer surface of the horizontal rod 801. The top of the two stop arms 17 is fixedly connected to the stop block 19.
[0032] The above scheme is adopted: by setting stop arms 17, the two stop arms 17 are pushed by push arms 15 respectively, slide close to each other on the surface of horizontal bar 801, and compress stop spring 18. The two stop arms 17 slide and then drive the two stop blocks 19 to move close to each other.
[0033] refer to Figure 3 and Figure 4Two stop blocks 19 are fixedly connected to the top of the two stop arms 17 on opposite sides, and the opposite ends of the two stop blocks 19 are inserted into the inner wall of the positioning groove 602.
[0034] The above solution is adopted: by setting stop blocks 19, the two stop blocks 19 can be disengaged from the positioning groove 602 when they move closer together, thereby releasing the fixation of the positioning block 601 and thus releasing the fixed connection between the active plate 6 and the passive plate 7.
[0035] The working principle of this utility model:
[0036] In use, place both ends of the body 2 to be polished on the rubber rings 401 of the two driven plates 7 respectively. Then, rotate the two active plates 6 and cover them on the driven plates 7, causing the positioning block 601 to move down and insert into the opening 701. As the positioning block 601 moves down, it presses the surfaces of the two stop blocks 19, causing them to move and then drive the two stop arms 17 to slide closer on the horizontal bar 801, compressing the stop spring 18. When the positioning block 601 is fully inserted into the opening 701, the stop spring 18 pushes the two stop arms 17 to slide away, and causes the two stop blocks 19 to insert into the positioning groove 60. 2. Fix the positioning block 601 to securely connect the active plate 6 and the passive plate 7. Clamp and position one end of the main body 2 using two rubber rings 401. Simultaneously, fix the other active plate 6 to the passive plate 7, thus completing the clamping and positioning of the main body 2. Then, merge the two sets of fixing rings 301, so that the two sets of fixing rings 301 respectively wrap around the two sets of active plates 6 and passive plates 7. Then, insert the two fixing handles 303 into the fixing rods 302 on both sides to fix the two sets of fixing rings 301. Finally, push the cylinder 102 to push the grinding machine 1. 03 Approaching the main body 2, simultaneously rotating it for grinding and cleaning. During this process, the user can rotate the fixed handle 303 to control the two fixed rings 301 via the two fixed rods 302, and rotate the top of the support arm 104 to adjust the rotation of the main body 2. After grinding, first remove the two fixed handles 303 and open the fixed rings 301, then push the driven member 10 backward, causing it to drive the movable slider 9 to slide backward in the horizontal groove 702, and drive the movable sliding arm 11 to move in the connecting groove 8, simultaneously driving the two movable sliding rods 12 to move backward. As rod 12 moves backward, it simultaneously presses against the inner walls of the two active slots 14, causing the two active arms 13 to rotate relative to each other. During rotation, the two push arms 15 follow the rotation. During the rotation, the two push arms 15 pass through the through-hole 16 to offset the horizontal rod 801 and push the two stop arms 17 to slide away from the horizontal rod 801. This causes the two stop blocks 19 to disengage from the positioning slot 602, releasing the fixation of the positioning block 601. This releases the fixed connection between the active plate 6 and the driven plate 7. Then, the rod rotates upward to release the fixation of one end of the main body 2. The above operation is repeated to release the fixation of the other end of the main body 2.
[0037] It should be noted that the drive cylinder 102 and the grinder 103 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. The specific composition and principle of the power supply of the drive cylinder 102 and the grinder 103 are clear to those skilled in the art, so they will not be described in detail here.
[0038] In summary, this alloy cast iron roll cleaning device, through the coordinated operation of the base 1, main body 2, fixed rotation component 3, fixing structure 4, and locking structure 5, solves the problem that if no positioning measures are taken for the alloy cast iron roll during grinding and cleaning, the roll may shift or rotate during the grinding and cleaning process, resulting in the grinding belt not being able to stably contact the roll surface and affecting the cleaning effect of the roll.
