Description

Technical Field

[0001] The invention relates to the technical field of bearing seat manufacturing, and in particular to a low temperature resistant and corrosion resistant bearing seat manufacturing process. Background Art

[0002] Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is what is commonly called the bearing seat. In a low-temperature, humid, and highly corrosive environment, it is necessary to select a bearing seat made of a material with good corrosion resistance, such as stainless steel, corrosion-resistant cast iron, etc. These materials can effectively resist the erosion of corrosive media, extend the service life of the bearing seat, and reduce the maintenance cost of the equipment.

[0003] During the production process of stainless steel bearing seats, it is necessary to move the steel blank and fix it on the lathe, and perform operations such as punching on its surface through a lathe tool. In order to pursue processing efficiency, the existing technology mostly relies on workers to move the steel blank. The disadvantage of this solution is that when the bearing seat model is large, the steel blank is heavy and the workers cannot move it easily.

[0004] At present, there is also a solution to lift the steel blanks through an overhead crane. The advantage of this solution is that the lifting mass is large, but there are still many inconveniences in the use of the overhead crane, such as: it is not easy to adapt to the shape of the steel blank. Since the bearing seat steel blanks are mostly solid cylindrical, most of the existing hoists are not easy to fix and the risk of falling is high; and the working stroke of the overhead crane is long. When moving some steels whose mass exceeds the limited manpower range, it is easy to cause low efficiency and energy waste; the most important thing is that the overhead crane is not convenient for stable movement of steel. Since the overhead crane is mostly connected to heavy objects by chains, it will shake during the movement, which not only further increases the safety risk, but also the processing of the bearing seat blank requires the steel to be aligned with the fixture on the lathe. Therefore, it is extremely inconvenient during use and needs to be improved. Summary of the invention

[0039] like Figures 1 to 15 As shown: A manufacturing process for a low-temperature-resistant and corrosion-resistant bearing seat includes the following steps: step 1: move a pair of frames 1 so that they are located on both sides of a steel material 17, and clamp the steel material 17 through a sling assembly 3 installed on the frame 1, which can adapt to the shape of the steel material 17 for easy lifting; step 2: a driving assembly 2 is installed on the frame 1, which can drive the sling assembly 3 to rise and lift the steel material 17, and an anti-fall mechanism 5 is installed on the sling assembly 3, which can further prevent the steel material 17 from falling during the lifting process; step 3: while lifting the steel material 17, the anti-sway assembly 4 installed on the frame 1 can fix the steel material 17 to prevent it from swinging during the movement; step 4: a universal wheel 11 is installed at the bottom of the frame 1, so that the frame 1 It can conveniently drive the steel 17 to move to a suitable position, and then adjust the steel 17 to align with the fixture on the lathe through the fine-tuning mechanism 46 installed on the frame 1, and install it on the lathe to be processed into a bearing seat.

Pushing the support column 12 to make the universal wheel 11 roll can drive the frame 1 and the steel 17 to move. The driving assembly 2 is installed on one of the frames 1.

The sling assembly 3 includes a shell 30, a pair of rotating shafts 31, a pair of clamping mechanisms 32, a card plate 33 and an anti-falling mechanism 5. The two rotating shafts 31 are symmetrically distributed on both sides of the shell 30. The top of the rotating shaft 31 is fixedly connected to the bottom of the shell 30. The clamping mechanism 32 includes a pair of clamping claws 320, a pair of vertical plates 321 and a thrust spring 322. The two pairs of clamping claws 320 are respectively rotatably connected to the outer periphery of the two rotating shafts 31. The two clamping claws 320 form an annular structure. The bottom of the vertical plate 321 is fixedly connected to the top of the clamping claws 320. A pair of empty slots 300 are opened at the top of the shell 30. The vertical plate 321 passes through the empty slots 300 and is slidably connected thereto. The two ends of the thrust spring 322 are respectively fixedly connected to the two vertical plates 321. A through slot 301 is opened on one side of the shell 30. The slot 301 is plug-fitted with the card plate 33. The two sides of the card plate 33 are respectively plug-fitted with the grooves on the vertical plate 321.The frame 1 is moved so that the steel 17 is located between the two frames 1, and the sling assembly 3 is lowered by the driving assembly 2, and the clamping mechanism 32 is aligned with the steel 17 and moved downward. At this time, the clamping claw 320 rotates around the rotating shaft 31 and opens to both sides under the push of the steel 17, and the vertical plate 321 rotates to pressurize the thrust spring 322 to compress it, and then the thrust spring 322 rebounds, and the clamping claw 320 is reset under the push of the thrust spring 322 to clamp the steel 17, and then the clamping plate 33 is inserted into the slot 301 to make it stuck between the two vertical plates 321, so that the vertical plate 321 is fixed and cannot rotate, preventing the clamping claw 320 from loosening, thereby facilitating the fixing of the steel 17, and the sling assembly 3 is lifted by the driving assembly 2, so that the steel 17 can be lifted. The anti-fall mechanism 5 is installed on the sling assembly 3, and the anti-fall assembly is used to prevent the steel 17 from falling when the clamping claw 320 is loose. The anti-sway assembly 4 is installed on the frame 1, and the anti-sway assembly 4 is used to prevent the steel 17 from swinging.

[0040] like Figures 1 to 11 As shown: The anti-fall mechanism 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 shell 30. A vertical groove 302 is provided at the top of the other end of the shell 30. The other end of the steel belt 50 is plugged into the vertical groove 302. A plurality of slots 500 are provided on the inner wall of the steel belt 50. The slots 500 are snap-fitted 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 outer 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 can be horizontally slidably installed in the shell 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 slot 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 outer periphery of the steel 17, one end of it is located at a suitable position in the vertical slot 302 and is locked with the buckle 51, so that the steel 17 can be supported when the clamp 320 is loosened, further preventing the risk of the steel 17 falling.

When the card plate 33 is inserted into the slot 301, the card plate 33 squeezes the push block 55 to make it slide into the slide slot 303. At this time, the long rod 54 pushes the connecting rod 52 and the buckle 51 to slide toward the vertical slot 302, the tension spring 56 is stretched, and the bottom of the buckle 51 and the bottom wall of the slide slot 303 are mutually abutted, so that the block can only rotate toward the top, thereby ensuring that the steel belt 50 can only be tightened and cannot be loosened during lifting. On the contrary, when the card plate 33 is separated from the slot 301, the tension spring 56 rebounds and drives the connecting rod 52 and the buckle 51 to move in the opposite direction, and the buckle 51 is separated from the card slot 500, so that it is easy to loosen the steel belt 50.

[0042] like Figures 1 to 13 As shown: The driving 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 bottom of the rotating seat 22 is fixedly connected with 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 with the bottom of the top plate 13. The other end of the steel cable 20 is fixedly connected with the outer periphery of the winding roller 21. The pulley 23 is installed on the top of the housing 30. The motor 24 is installed on the top plate 13. The motor 24 is used to drive the winding roller 21 to rotate. The motor 24 is powered on to drive the winding roller 21 to rotate, the steel cable 20 is rotated and tightened, and the pulley 23 and the housing 30 are driven to rise, so that the steel material 17 can be hoisted.

[0043] like Figures 1 to 15 As shown: 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, an extrusion block 44, a second torsion spring 45 and a linkage mechanism 6.

The thread 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 thereto, 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 respectively rotatably connected to the two sides of the extrusion block 44, the second torsion spring 45 is sleeved on one side of the extrusion block 44, and the two ends of the second torsion spring 45 are respectively connected to the two telescopic rods 43. The telescopic end is fixedly connected to rotate the bidirectional threaded rod 40. Through the threaded transmission between the two sliders 42 and the two sliders 42, the two sliders 42 slide up and down along the guide rod 41 and approach each other, pushing the two telescopic rods 43 to rotate around the sliders 42. In this process, the second torsion spring 45 is compressed. Under the rebound force of the second torsion spring 45, the two telescopic rods 43 maintain a vertical trend, so that the telescopic ends of the two telescopic rods 43 protrude and push the extrusion block 44 to move horizontally close to the shell 30. When the extrusion block 44 fits the shell 30, as the movement continues, the telescopic rod 43 shortens and consumes the excess stroke, thereby limiting the shell 30 through the extrusion blocks 44 on both sides, preventing the steel 17 from swinging and causing unstable movement, and failing to align with the lathe fixture. The linkage mechanism 6 is installed on the frame 1, and the linkage mechanism 6 is used to drive the bidirectional threaded rod 40 to rotate.

When the telescopic rod 43 is squeezed, one end of the slide bar 431 slides in the sleeve 430, thereby realizing the telescopic function. At the same time, the slide bar 431 squeezes the spring damper 432, and the vibration transmitted by the slide bar 431 is absorbed by the spring damper 432, further preventing the steel material 17 from swinging, and achieving a certain shock absorbing effect.

[0045] like Figures 1 to 14 As shown: The linkage mechanism 6 includes a support seat 60, a transmission rod 61, a second bevel gear 62 and a universal joint 63.
