Description

Technical Field

[0001] The invention belongs to the technical field of bearing fixing, and in particular relates to an adjustable bearing fixing device. Background Art

[0002] In current strip steel production processes, furnace roller bearing bases are commonly installed using a fixed method, securely fastened directly to the furnace frame. While this installation method offers advantages such as structural stability and ease of installation, it has a significant drawback: once installed, the angle and position of the furnace roller bearing base cannot be adjusted.

[0003] During strip production, numerous factors can cause the strip to exhibit abnormalities. For example, defects in the strip's profile, such as wavy edges or bowing in the center, can lead to uneven stress distribution within the furnace. Uneven heating within the furnace, with areas of the strip overheating or underheating, can cause different areas of the strip to expand at different rates, affecting its trajectory. These factors can easily cause the strip to stray at the furnace exit.

[0004] Once a strip deviates, it can cause a series of serious production problems. Minor deviations can lead to slowdowns, as operators must reduce production speeds to minimize the impact on product quality while seeking a solution. However, when deviation becomes severe, the strip edge can scrape against the furnace or other equipment, causing edge scraping. As the deviation worsens, the strip may even break, a severe strip break. Strip breaks not only render the currently produced strip scrapped, resulting in a waste of raw materials, but also force production line downtime for equipment maintenance and cleanup, significantly increasing production costs and lead times.

Since the mounting block 1 is located inside the bearing body, the bearing body can be limited and fixed. Finally, the extrusion block is moved away from the inside of the fixed shell by driving the motor, and the resilience of the elastic part is used to adsorb the neodymium magnet on the surface of the slide rail 1, so that the bearing body can be fixed, thereby improving the accuracy and stability of the angle adjustment between the strip steel and the furnace roller, and providing a strong guarantee for the high-quality and high-efficiency operation of the strip steel production.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1 to 6 As shown, the present invention provides an adjustable bearing fixing device, comprising a base 1 and a bearing body 7, and further comprising:

[0033] An adjusting mechanism 2 is provided at the top of the base 1. The adjusting mechanism 2 includes a slide rail 201 fixedly connected to the top of the base 1, and the bearing body 7 can slide on the surface of the slide rail 201. A fixed shell 202 is provided on one side of the slide rail 201. A mounting block 203 located inside the bearing body 7 is fixedly installed on the side of the fixed shell 202 close to the slide rail 201. A motor 204 is fixedly installed on the top of the base 1. A screw rod 205 is fixedly installed on the output end of the motor 204. A threaded block 206 is threadedly sleeved on the surface of the screw rod 205. An extrusion block 207 located inside the fixed shell 202 is fixedly installed on one side of the threaded block 206. A connecting block 208 is fixedly installed on the top and bottom ends of the extrusion block 207.

[0034] The fixing mechanism 3 is disposed at the bottom end of the fixing shell 202 .

[0035] The above solution is adopted: the operator can drive the motor 204 to rotate the screw rod 205. Since the screw rod 205 is threadedly connected to the threaded block 206, the threaded block 206 will slide on the surface of the rotating screw rod 205. Then the threaded block 206 will drive the extrusion block 207 and the connecting block 208 to move. During the movement of the extrusion block 207, it will push the fixing mechanism 3 to cancel the fixation of the bearing body 7. Then the surface of the connecting block 208 will contact one side of the fixed shell 202. As the connecting block 208 continues to advance, the connecting block 208 will push the fixed shell 202 to move, and the fixed shell 202 will drive the installation block 203 to move. Since the installation block 203 is located inside the bearing body 7, the moving installation block 203 will push the bearing body 7 to slide on the surface of the slide rail 201, thereby adjusting the position of the bearing body 7. Finally, the connecting block 208 is driven by the motor 204 to push the fixed shell 202 and the bearing body 7 to move, thereby adjusting the angle between the strip and the furnace roller, and controlling it within the range of seventy-five to one hundred and five degrees, effectively improving the deviation of the running direction of the furnace roller and the strip, improving the processing quality of the strip, and reducing production failures and scrap rates caused by deviation.

[0036] like Figure 3 、 Figure 4 and Figure 6 As shown, the fixing mechanism 3 includes a second slide rail 301 arranged at the bottom end of the fixed shell 202, and the second slide rail 301 is fixedly connected to the top of the base 1. The surface of the second slide rail 301 is slidably connected to the second slider 302. A U-shaped plate 303 is fixedly installed on one side of the second slider 302. The U-shaped plate 303 is elastically connected to the fixed shell 202 through an elastic member 304. A neodymium magnet 305 is fixedly installed on the side of the mounting block 1 203 close to the first slide rail 201.

[0037] With the above solution, through the design of the fixing mechanism 3, when the extrusion block 207 moves, it squeezes and pushes the fixed shell 202 to move. When the fixed shell 202 moves, the elastic member 304 is compressed, and then the fixed shell 202 pulls the mounting block 1 203 and the neodymium magnet 305 away from the surface of the slide rail 1 201, thereby canceling the fixation of the bearing body 7. Then, the connecting block 208 pushes the fixed shell 202 to move. When the fixed shell 202 moves, the elastic member 304, the U-shaped plate 303 and the second slider 302 slide on the surface of the second slide rail 301.

[0038] When the bearing body 7 moves to the specified position, the motor 204 can be used again to make the screw rod 205 rotate in the opposite direction, and the threaded block 206 will pull the extrusion block 207 away from the fixed shell 202. At this time, the compressed elastic member 304 will push the fixed shell 202, the mounting block 203 and the neodymium magnet 305 to move toward the surface of the slide rail 1 201, and then the neodymium magnet 305 will contact the surface of the slide rail 1 201, and the magnetic force of the neodymium magnet 305 will make it adsorbed on the surface of the slide rail 1 201. Since the mounting block 1 203 is located inside the bearing body 7, the bearing body 7 can be limited and fixed. Finally, the extrusion block 207 is moved away from the inside of the fixed shell 202 by driving the motor 204, and the resilience of the elastic member 304 is used to make the neodymium magnet 305 adsorbed on the surface of the slide rail 1 201, so that the bearing body 7 can be fixed, thereby improving the accuracy and stability of the angle adjustment of the strip steel and the furnace roller, and providing a strong guarantee for the high-quality and high-efficiency operation of the strip steel production.

[0039] like Figure 6 As shown, it also includes:

[0040] The rolling assembly 4 is arranged on both sides of the surface of the second slide rail 301. The rolling assembly 4 includes slide grooves 401 opened on both sides of the surface of the second slide rail 301. The interior of the second slider 302 is rollingly connected with the ball 402 located inside the slide groove 401.

[0041] Adopting the above-mentioned scheme: through the design of the rolling component 4, when the slider 2 302 slides on the surface of the slide rail 2 301, it will drive the ball 402 to roll inside the slide groove 401, thereby enabling the slider 2 302 to move more smoothly, and the surface of the ball 402 fits with the inner wall of the slide groove 401, and then cooperates with the slide rail 2 301 to limit the slider 2 302.

[0042] like Figure 4 As shown, it also includes:

[0043] The limiting component 5 is arranged inside the fixed shell 202. The limiting component 5 includes a fixing groove 501 opened inside the fixed shell 202. The internal sliding connection of the fixing groove 501 is a limiting block 502, and the bottom end of the limiting block 502 is fixedly connected to the surface of the threaded block 206.

[0044] Adopting the above-mentioned scheme: through the design of the limiting component 5, the threaded block 206 will drive the limiting block 502 to slide inside the fixed groove 501 in the process of driving the extrusion block 207 to move, and during the sliding process, the threaded block 206 can be limited to ensure that the threaded block 206 can move stably on the surface of the screw rod 205.

[0045] like Figure 5 As shown, it also includes:

[0046] The support assembly 6 is arranged on the surface of the screw rod 205. The support assembly 6 includes a support plate 601 arranged on the surface of the screw rod 205, and the support plate 601 is fixedly connected to one end of the slide rail 2 301. The surface of the screw rod 205 is fixedly connected with a limit plate 602 located on both sides of the support plate 601.

[0047] Adopting the above solution: through the design of the support assembly 6, when the screw rod 205 rotates, it will drive the limit plate 602 to rotate on both sides of the support plate 601. The support plate 601 can support the screw rod 205, and the limit plate 602 can limit the screw rod 205.

[0048] like Figure 5 As shown, the extrusion block 207 is designed as a mirror image, and the side of the extrusion block 207 opposite to the fixed shell 202 is designed as an inclined surface, and the two inclined surfaces are designed to be parallel.

[0049] The above solution is adopted: through the design of the fixed shell 202 and the extrusion block 207, since the extrusion block 207 is a mirror image design, it can drive the bearing body 7 to move left and right, and the side of the extrusion block 207 opposite to the fixed shell 202 is a bevel design, which can reduce the friction between the extrusion block 207 and the fixed shell 202, making it easier for the extrusion block 207 to squeeze the fixed shell 202 to move.

[0050] like Figure 2 and 6 As shown, a telescopic rod is provided inside the elastic member 304 , and both ends of the telescopic rod are fixedly connected to the U-shaped plate 303 and the fixed shell 202 . A threaded hole is provided at the bottom end of the base 1 , and there are multiple threaded holes.

[0051] The above solution is adopted: through the design of the elastic member 304, when the elastic member 304 is squeezed, the telescopic rod will shrink, and the shrinking telescopic rod can limit the elastic member 304 and support the fixed shell 202. Through the design of the base 1, since the bottom end of the base 1 is provided with a threaded hole, the base 1 can be fixed on the furnace body frame, and there are multiple threaded holes, thereby ensuring the stability of the fixation.

[0052] like Figure 2 and 5 As shown, baffles are fixedly installed on both sides of the second slide rail 301, and the baffles are mirror-image designs. A protective shell located on the surface of the motor 204 is fixedly installed on the top of the base 1, and a gap is provided between the fixed shell 202 and the second slider 302.

[0053] The above solution is adopted: through the design of the slide rail 2 301, since both ends of the slide rail 2 301 are baffles, the movement of the slider 2 302 can be blocked, and the slider 2 302 can be prevented from separating from the surface of the slide rail 2 301. Through the design of the motor 204 and the fixed shell 202, since a protective shell is provided on the surface of the motor 204, the motor 204 can be protected, thereby improving the service life of the motor 204, and a gap is provided between the fixed shell 202 and the slider 2 302, so that the moving fixed shell 202 and the slider 2 302 do not interfere with each other.

[0054] The working principle and use process of the present invention:

[0055] First, the operator uses bolts to fasten the base 1 to the furnace frame. When the strip steel deviates, the motor 204 can be driven to rotate the screw rod 205. The threaded block 206 will slide on the surface of the screw rod 205. The threaded block 206 will drive the extrusion block 207 and the connecting block 208 to move. During the movement of the extrusion block 207, it will squeeze and push the fixed shell 202 to move. At this time, the elastic member 304 will be compressed, and the fixed shell 202 will pull the mounting block 203 and the neodymium magnet 305 away from the surface of the slide rail 201, thereby canceling the fixation of the bearing body 7 and the surface of the connecting block 208. The surface will contact one side of the fixed shell 202. As the connecting block 208 continues to advance, the connecting block 208 will push the fixed shell 202 to move. The fixed shell 202 will push the elastic member 304, the U-shaped plate 303 and the second slider 302 to slide on the surface of the second slide rail 301. The fixed shell 202 will also drive the mounting block 1 203 to move. Since the mounting block 1 203 is located inside the bearing body 7, the moving mounting block 1 203 will push the bearing body 7 to slide on the surface of the first slide rail 201, thereby adjusting the position of the bearing body 7 and improving the deviation of the furnace roller and the running direction of the strip.

[0056] When the bearing body 7 moves to the specified position, the motor 204 can be used again to make the screw rod 205 rotate in the opposite direction, and the threaded block 206 will pull the extrusion block 207 away from the fixed shell 202. At this time, the compressed elastic member 304 will push the fixed shell 202, the mounting block 203 and the neodymium magnet 305 to move toward the surface of the slide rail 201, and then the neodymium magnet 305 will contact the surface of the slide rail 201. The magnetic force of the neodymium magnet 305 will make it adsorbed on the surface of the slide rail 201. Since the mounting block 203 is located inside the bearing body 7, the bearing body 7 can be limited and fixed, thereby improving the accuracy and stability of the angle adjustment between the strip steel and the furnace roller, and finally completing the operation process.
