Description

Technical Field

[0001] This invention relates to the field of bearing housing manufacturing technology, and specifically to a manufacturing process for a low-temperature resistant and corrosion-resistant bearing housing. Background Technology

[0002] Where there are bearings, there must be support points. The inner support point of a bearing is the shaft, and the outer support is what is commonly referred to as the bearing housing. In low-temperature, humid, and highly corrosive environments, bearing housings made of materials with good corrosion resistance are required, such as stainless steel and corrosion-resistant cast iron. These materials can effectively resist the erosion of corrosive media, extend the service life of the bearing housing, and reduce equipment maintenance costs.

[0003] In the production process of stainless steel bearing housings, it is necessary to move the steel blank and fix it on a lathe, and perform operations such as punching on its surface using a lathe tool. In order to pursue processing efficiency, most existing technologies rely on workers to move the steel blank. The disadvantage of this approach is that when the bearing housing model is large, the steel blank is heavy and cannot be easily moved by workers.

[0004] Another solution is to use an overhead crane to lift steel billets. This method has the advantage of high lifting capacity, but overhead cranes still have many inconveniences in use. For example, they are not easy to adapt to the shape of the steel billets. Since most bearing housing steel billets are solid cylinders, existing lifting devices are mostly difficult to fix, resulting in a high risk of falling. Furthermore, the long working stroke of the overhead crane can easily lead to low efficiency and energy waste when moving steel billets whose weight exceeds the limits of human strength. Most importantly, overhead cranes are not convenient for stable movement of steel. Since overhead cranes mostly connect heavy objects with chains, swaying occurs during movement, further increasing safety risks. Moreover, processing the bearing housing billets requires aligning the steel with the fixtures on a lathe, making it extremely inconvenient to use and requiring improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a manufacturing process for low-temperature and corrosion-resistant bearing housings that can stably and quickly move steel blanks, reduce the workload of workers, and lower safety risks.

[0047] like Figures 1 to 15 As shown:

[0048] A manufacturing process for a low-temperature and corrosion-resistant bearing housing includes the following steps: Step 1: Move a pair of frame bodies 1 to position them on both sides of a steel material 17. The steel material 17 is clamped by a lifting assembly 3 installed on the frame body 1, which can adapt to the shape of the steel material 17 for easy lifting. Step 2: A drive assembly 2 is installed on the frame body 1, which can drive the lifting assembly 3 to rise and lift the steel material 17. An anti-fall mechanism 5 is installed on the lifting assembly 3 to further prevent the steel material 17 from falling during lifting. Step 3: While lifting the steel material 17, an anti-sway assembly 4 installed on the frame body 1 can fix the steel material 17 to prevent it from swinging during movement. Step 4: Universal wheels 11 are installed at the bottom of the frame body 1, allowing the frame body 1 to... It can easily move the steel 17 to a suitable position, and then adjust the steel 17 to align with the fixture on the lathe through the fine adjustment mechanism 46 installed on the frame 1, and install it on the lathe to be processed into a bearing seat. It also includes a pair of frames 1, a drive assembly 2, a lifting assembly 3 and a pair of anti-sway assemblies 4. The two frames 1 are detachably connected. The frame 1 includes a base 10, multiple casters 11, a support column 12 and a top plate 13. The multiple casters 11 are respectively installed at the four corners of the bottom of the base 10. The bottom of the support column 12 is fixedly connected to the top of the base 10, and one end of the support column 12 is fixedly connected to the top of the vertical plate 321. Pushing the support column 12 to make the casters 11 roll can drive the frame 1 and the steel 17 to move. The drive assembly 2 is installed on one of the frames 1. The drive assembly 2 is used to drive the lifting assembly 3 to lift and lower. The lifting assembly 3 includes a housing 30, a pair of rotating shafts 31, a pair of clamping mechanisms 32, a clamping plate 33, and a fall protection mechanism 5. The two rotating shafts 31 are symmetrically distributed on both sides of the housing 30. The top of the rotating shafts 31 is fixedly connected to the bottom of the housing 30. The clamping mechanism 32 includes a pair of jaws 320, a pair of vertical plates 321, and a thrust spring 322. The two pairs of jaws 320 are rotatably connected to the periphery of the two rotating shafts 31 respectively. The two jaws 320 form a ring structure. The bottom of the vertical plate 321 is fixedly connected to the top of the jaws 321. A pair of slots 300 are opened on the top of the housing 30. The vertical plates 321 pass through the slots 300 and are slidably connected to them. The two ends of the thrust spring 322 are fixedly connected to the two vertical plates 321 respectively. A through slot 301 is opened on one side of the housing 30. The slot 301 is inserted into the clamping plate 33. The two sides of the clamping plate 33 are respectively engaged with the grooves on the vertical plates 321.The moving frame 1 positions the steel 17 between the two frames 1. The lifting assembly 3 is lowered by the drive assembly 2, and the clamping mechanism 32 moves down aligned with the steel 17. At this time, the jaws 320 rotate around the pivot 31 and open to both sides under the push of the steel 17. The vertical plate 321 rotates and compresses the thrust spring 322. Then the thrust spring 322 rebounds, and the jaws 320 reset under the push of the thrust spring 322, clamping the steel 17. Then the clamping plate 33 is inserted into the slot 301 and locked between the two vertical plates 321, fixing the vertical plates 321 so that they cannot rotate and preventing the jaws 320 from loosening. This makes it easier to fix the steel 17. The lifting assembly 3 is then lifted by the drive assembly 2, and the steel 17 can be lifted. The fall protection mechanism 5 is installed on the lifting device assembly 3. The fall protection assembly is used to prevent the steel 17 from falling when the gripper 320 is loose. The anti-sway assembly 4 is installed on the frame 1. The anti-sway assembly 4 is used to prevent the steel 17 from swinging.

[0049] like Figures 1 to 11 As shown:

[0050] The fall arrestor 5 includes a steel belt 50, a buckle 51, a connecting rod 52, and a first torsion spring 53. The top of one end of the steel belt 50 is fixedly connected to the bottom of one end of the housing 30. A through vertical groove 302 is opened at the top of the other end of the housing 30. The other end of the steel belt 50 is inserted into the vertical groove 302. Multiple slots 500 are opened on the inner wall of the steel belt 50. The slots 500 are engaged with one end of the buckle 51. The other end of the buckle 51 is rotatably connected to the bottom of the connecting rod 52. The first torsion spring 53 is sleeved on the periphery of one end of the buckle 51. The two ends of the first torsion spring 53 are fixedly connected to the buckle 51 and the connecting rod 52 respectively. The connecting rod 52 is horizontally slidably installed inside the housing 30. After the clamping mechanism 32 lifts the steel 17 off the ground, the steel belt 50 is moved to pass through the bottom of the steel 17 and insert into the vertical groove 302. At this time, the steel belt 50 squeezes and pushes one end of the buckle 51 to rotate upward, the first torsion spring 53 is compressed, and then the first torsion spring 53 rebounds and pushes the buckle 51 into one of the slots 500. When the steel belt 50 is tightened and covers the outside of the steel 17, one end of it is located in a suitable position in the vertical groove 302 and locked with the buckle 51. This can support the steel 17 when the gripper 320 is loose, further preventing the risk of the steel 17 falling.

[0051] like Figures 1 to 11 As shown:

[0052] The fall arrestor 5 also includes a long rod 54, a push block 55, and a tension spring 56. One end of the long rod 54 is fixedly connected to the top of the connecting rod 52, and the other end of the long rod 54 is fixedly connected to the push block 55. A sliding groove 303 is provided inside the housing 30. One end of the sliding groove 303 is connected to the slot 301, and the other end of the sliding groove 303 is connected to the vertical groove 302. The bottom of the sliding groove 303 is slidably connected to the connecting rod 52 and the buckle 51, and the top of the sliding groove 303 is slidably connected to the long rod 54 and the push block 55. The tension spring 56 is sleeved around the long rod 54. One end of the tension spring 56 is fixedly connected to the connecting rod 52, and the other end of the tension spring 56 is fixedly connected to the inner wall of the empty groove 300. When the locking plate 33 is inserted into the slot 301, it presses against the pusher block 55, causing it to slide into the slide groove 303. At this time, the long rod 54 pushes the connecting rod 52 and the buckle 51 to slide towards the vertical groove 302. The tension spring 56 is stretched, and the bottom of the buckle 51 abuts against the bottom wall of the slide groove 303, so that the locking block can only rotate upwards, thus ensuring that the steel strip 50 can only be tightened and cannot be loosened during lifting. Conversely, when the locking plate 33 is disengaged from the slot 301, the tension spring 56 rebounds, causing the connecting rod 52 and the buckle 51 to move in the opposite direction, and the buckle 51 disengages from the locking groove 500, thus facilitating the release of the steel strip 50.

[0053] like Figures 1 to 13 As shown:

[0054] The drive assembly 2 includes a steel cable 20, a winding roller 21, a pair of rotating seats 22, a pulley 23, and a motor 24. The steel cable 20 is wound around the periphery of the winding roller 21. Both sides of the winding roller 21 are rotatably connected to the two rotating seats 22. The bottom of the rotating seats 22 is fixedly connected to the top of one of the top plates 13. One end of the steel cable 20 passes through the bottom of the pulley 23 and is fixedly connected to the bottom of the top plate 13. The other end of the steel cable 20 is fixedly connected to the periphery of the winding roller 21. The pulley 23 is mounted on the top of the housing 30. The motor 24 is mounted on the top plate 13 and is used to drive the winding roller 21 to rotate. When the motor 24 is energized, it drives the winding roller 21 to rotate, causing the steel cable 20 to rotate and tighten, which in turn drives the pulley 23 and the housing 30 to rise, thus lifting the steel 17.

[0055] like Figures 1 to 15 As shown:

[0056] The anti-sway assembly 4 includes a bidirectional threaded rod 40, a guide rod 41, a pair of sliders 42, a pair of telescopic rods 43, a pressing block 44, a second torsion spring 45, and a linkage mechanism 6. The bidirectional threaded rod 40 is rotatably installed inside the support column 12, and the guide rod 41 is fixedly installed inside the support column 12. One side of the slider 42 is threadedly connected to the outer periphery of the bidirectional threaded rod 40, and the other side of the slider 42 is slidably connected to the outer periphery of the guide rod 41. The threaded grooves on the two sliders 42 are in opposite directions. One end of the slider 42 passes through the side wall of the support column 12 and is slidably connected to it. One end of the telescopic rod 43 is rotatably connected to the slider 42, and the telescopic ends of the two telescopic rods 43 are rotatably connected to both sides of the pressing block 44, respectively. The second torsion spring 45 is sleeved on one side of the pressing block 44, and both ends of the second torsion spring 45 are respectively connected to the two telescopic rods 43. The telescopic end is fixedly connected, causing the bidirectional threaded rod 40 to rotate. Through the threaded transmission between the rod and the two sliders 42, the two sliders 42 slide up and down along the guide rod 41 and move closer to each other, pushing the two telescopic rods 43 to rotate around the sliders 42. During this process, the second torsion spring 45 is compressed. Under the action of the rebound force of the second torsion spring 45, the two telescopic rods 43 maintain a vertical tendency, so that the telescopic ends of the two telescopic rods 43 protrude and push the extrusion block 44 to move horizontally closer to the housing 30. When the extrusion block 44 is in contact with the housing 30, as the movement continues, the telescopic rods 43 shorten to consume the excess stroke, thereby limiting the housing 30 through the extrusion blocks 44 on both sides, preventing the steel 17 from swinging and causing unstable movement, and preventing it from being aligned with the lathe fixture. The linkage mechanism 6 is installed on the frame 1 and is used to drive the bidirectional threaded rod 40 to rotate.

[0057] like Figures 1 to 15 As shown:

[0058] The telescopic rod 43 includes a sleeve 430, a slide rod 431, and a spring damper 432. One end of the sleeve 430 is rotatably connected to the slider 42, one end of the slide rod 431 is slidably connected to the other end of the sleeve 430, and the other end of the slide rod 431 is rotatably connected to the pressing block 44. One end of the spring damper 432 is fixedly connected to the inner wall of the sleeve 430, and the telescopic end of the spring damper 432 is fixedly connected to the slide rod 431. When the telescopic rod 43 is compressed, one end of the slide rod 431 slides inside the sleeve 430, thereby realizing the telescopic function. At the same time, the slide rod 431 compresses the spring damper 432, and the spring damper 432 absorbs the vibration transmitted by the slide rod 431, further preventing the steel 17 from swaying and providing a certain degree of shock absorption.

[0060] The linkage mechanism 6 includes a support base 60, a transmission rod 61, a second bevel gear 62, and a universal joint 63.

When the motor 24 drives the round rod 25 to rotate, it can rotate the winding roller 21. At the same time, it can also drive the first bevel gear 26 to rotate. Through the meshing transmission between the first bevel gear 26 and the second bevel gear 62, the transmission rod 61 and the universal joint 63 are driven to rotate. And through the universal joint 63, the bidirectional threaded rod 40 is rotated, thereby causing the slider 42 to slide vertically and drive the anti-sway component 4 to limit the steel 17.

[0062] It also includes a fine-tuning mechanism 46, which includes a hydraulic rod 460. One end of the hydraulic rod 460 is fixedly connected to the frame 1 on which the lifting assembly 3 is installed. The telescopic end of the hydraulic rod 460 passes through the support column 12 and abuts against the pressing block 44. During the process of fixing the steel 17 on the lathe, the hydraulic rod 460 works to slowly push the pressing block 44, causing the housing 30 and the steel cable 20 to shift at a certain angle, which allows for fine adjustment of the position of the steel 17, facilitating the fixing of the steel 17.

[0063] like Figures 1 to 5 As shown:

[0064] One of the top plates 13 has its other end fixedly connected to a pair of insert plates 14. The insert plates 14 are inserted into the other end of the other top plate 13. The insert plates 14 are connected to the top plate 13 on which the lifting assembly 3 is installed by bolts 15. The frame 1 on which the lifting assembly 3 is installed also includes multiple support bars 16. The bottom of the support bars 16 is fixedly connected to the top of the base 10 at the end away from the lifting assembly 3. The two frames 1 are detachably connected by insert plates 14 and bolts 15. When the space in the lifting position area is small, the two frames 1 can be separated, and a counterweight can be placed on the top of the support bars 16. The lifting can then be carried out by the frame 1 on which the lifting assembly 3 is installed, which improves the practicality of the device.

[0065] like Figures 1 to 9 As shown:

[0066] The clamping plate 33 includes a long plate 330 and a pair of rotating plates 331. The two rotating plates 331 are rotatably connected to both sides of the long plate 330, and the two rotating plates 331 abut against both sides of the housing 30. When the clamping plate 33 is inserted into the slot 301, the rotating plates 331 are rotated 90 degrees so that they are bottom-to-bottom with the side wall of the housing 30, which can lock the clamping plate 33 into the slot 301, preventing it from slipping out due to external force and further improving the stability of the lifting device assembly 3.
