Description

Technical Field

[0001] This application relates to the technical field of bearing housing manufacturing, and in particular, to a flange-produced bearing housing and its manufacturing method. Background Art

[0002] A flange bearing housing is a tool for assembling and fixing a bearing. Using a combined processing machine to process the flange bearing housing can improve the processing efficiency and ensure the centralized and complete processing of the process without subsequent continuous conveying and processing. When using a combined processing machine to process the flange bearing housing, a clamping device is needed to fix the flange bearing housing to ensure the stability of the flange bearing housing processing.

[0003] Among them, the publication number is CN212019431U, named a fixture for processing a flange bearing housing. The fixture includes a base shell, a movable member, and a backing plate. The backing plate is installed on the base shell, the movable member is movably arranged on the base shell, the movable member is located between the base shell and the backing plate, and the movable member is used to externally connect a driving mechanism; at least two clamping jaws are spaced apart on the movable member, and the clamping jaws protrude from one end of the backing plate to the other end of the backing plate, and the clamping jaws are used to fix the flange bearing housing on the backing plate. By using the clamping jaws to clamp and fix the flange bearing housing on the backing plate and then performing machining, the present invention is convenient to operate and accurate in positioning when clamping the bearing housing.

[0004] The above-mentioned prior art uses rotating clamping jaws to fix the flange bearing housing. Although this structure can be positioned when fixing the bearing housing, it cannot ensure that the bearing housing is positioned at the central position, resulting in the processing mechanism being unfavorable for accurately processing the central hole position of the bearing housing. Summary of the Invention

[0005] In order to quickly and accurately position and fix the flange bearing housing to achieve a more precise processing purpose, this application provides a flange-produced bearing housing and its manufacturing method.

[0006] In a first aspect, this application provides a flange-produced bearing housing, adopting the following technical solution: A flange production bearing seat, comprising a workbench which is horizontally arranged. The workbench includes a top plate, side plates and a bottom plate. The top plate is fixedly connected to the side plates, and the side plates are fixedly connected to the bottom plate. A turntable is coaxially arranged on the workbench. A middle column is fixed at the bottom of the turntable. A first servo motor is fixed at the bottom of the middle column. The first servo motor drives the middle column to rotate bidirectionally relative to the bottom plate. The rotation axis direction of the middle column is along the vertical direction. Three clamping plates are arranged at intervals on the periphery of the turntable. The three clamping plates are distributed in an equilateral triangle. Three sliding holes are spaced apart along the periphery of the turntable on the top plate. The sliding holes are arranged along the radial direction of the turntable itself. A connecting rod is fixed on the clamping plate. The clamping plate is slidably connected to the workbench. The clamping plate reciprocally slides in a direction close to or away from the center point of the turntable. A turntable for driving the three clamping plates to approach or move away from each other simultaneously is arranged on the middle column. The connecting rod passes through the sliding hole and is connected to the turntable.

[0007] By adopting the above technical solution, place the flange bearing seat to be processed on the turntable. At this time, it cannot be ensured that the placement position of the flange bearing seat is at the center position. First, rotate the turntable. At this time, the three clamping plates simultaneously approach the flange bearing seat. Because the three clamping plates are distributed in an equilateral triangle, the center of the three clamping plates is also the center of the turntable. The rotation of the middle column drives the rotation of the turntable. And while the turntable is rotating, the turntable is also rotating. Therefore, while the flange bearing seat is rotating following the turntable, the three clamping plates will simultaneously clamp and fix the flange bearing seat. Similarly, when it is necessary to remove the flange bearing seat, only need to rotate the middle column in the reverse direction to drive the clamping plate away from the flange bearing seat.

[0008] Optionally, the turntable is fixedly connected to the middle column. Three through holes are spaced apart on the turntable. The through holes are opened from the center position of the turntable along the circumferential direction of the turntable gradually towards the edge of the turntable. The connecting rod passes through the through hole and slides along the length direction of the through hole.

[0009] By adopting the above technical solution, the turntable is fixed to the middle column. When the middle column rotates, the turntable also rotates together. Since the through holes on the turntable are opened from the center position gradually towards the edge, when the turntable rotates, the turntable will drive the connecting rod to move. The connecting rod is simultaneously under the limiting action of the sliding hole on the top plate of the workbench, so that the clamping plate and the connecting rod can move towards each other or away from each other simultaneously.

[0010] Optionally, the clamping plate itself is provided with a curvature. A plurality of rotating rollers are rotatably connected to the clamping plate. The plurality of rotating rollers are spaced apart along the arc length direction of the clamping plate. The rotation axis direction of the rotating roller is along the vertical direction. A receiving box is fixed on one side of the clamping plate facing away from each other. The receiving box is fixed to the connecting rod. When the rotating roller abuts against the flange bearing seat, the rotating roller gradually slides into the receiving box.

[0011] By adopting the above technical solution, the arc of the clamping plate itself is to adapt to the shape of the flange bearing seat. When multiple rollers approach the flange bearing seat, they first come into contact with the flange bearing seat, and at the same time, the rollers gradually move into the receiving box. This can not only reduce the wear on the edge of the flange bearing seat but also not affect the clamping and fixing of the flange bearing seat by the clamping plate.

[0012] Optionally, a rotating rod is coaxially arranged on the roller, the roller rotates relative to the rotating rod, a spring is fixed on the rotating rod, and one end of the spring away from the rotating rod is fixed to the receiving box. When the roller comes into contact with the flange bearing seat, the spring is in a compressed state.

[0013] By adopting the above technical solution, when the roller comes into contact with the flange bearing seat, it will compress the spring and move into the receiving box at the same time. The spring is gradually compressed, which can provide some buffering for the movement of the roller and facilitate increasing the service life of the roller.

[0014] Optionally, a plurality of enclosing plates are arranged on the workbench, and the plurality of enclosing plates are arranged at intervals along the circumferential direction of the top plate. The height of the enclosing plates is higher than that of the top plate. A plurality of air blowing openings are arranged at intervals on the side of the enclosing plates facing the turntable. The enclosing plates slide reciprocally in the vertical direction relative to the top plate, and a sliding component for driving the enclosing plates to slide is arranged in the workbench.

[0015] By adopting the above technical solution, the height of the enclosing plates is set higher than the workbench surface at the beginning, which can effectively prevent the flange bearing seat from falling out of the workbench. After the flange bearing seat is processed, the enclosing plates are raised again, and the air blowing openings on the enclosing plates can clean the workbench surface.

[0016] Optionally, the sliding component includes a threaded sleeve, a connecting block, and a support rod. The threaded sleeve is rotatably connected to the middle column, the connecting block is threadedly connected to the threaded sleeve, one end of the support rod is fixed to the connecting block, and the other end is fixed to the enclosing plate. A driving component for driving the threaded sleeve to rotate is arranged in the workbench.

[0017] By adopting the above technical solution, when the threaded sleeve is rotated, the threaded sleeve is threadedly connected to the connecting block. Due to the limiting effect of the plurality of support rods and the enclosing plate, the connecting block can move in the vertical direction. At this time, while the connecting block moves upward, it can drive the enclosing plate upward.

[0018] Optionally, the driving component includes a driving gear, a driven gear, and a second servo motor. The second servo motor is fixed to the bottom plate, the motor shaft of the second servo motor is fixed to the driving gear, the threaded sleeve is fixed to the driven gear, and the driving gear and the driven gear are meshed.

[0019] By adopting the above technical solution, when the second servo motor is started, it drives the driving gear to rotate. The driving gear is meshed with the driven gear, thereby driving the threaded sleeve to rotate. When the threaded sleeve rotates, the driving of the connecting block can be realized, that is, the rising of the enclosing plate can be realized. Similarly, when the enclosing plate needs to descend, just start the servo motor in the reverse direction.

[0020] Optionally, the inside of the surrounding plate is hollow, a hair dryer is fixedly connected to the bottom of the surrounding plate, a dust collection box for collecting dust is fixedly installed at the bottom of the turntable, and the turntable and the dust collection box slide vertically relative to the top plate.

[0021] By adopting the above technical solution, after the flange bearing seat is processed, when the air outlet on the surrounding plate cleans the workbench surface, the turntable is raised to expose the dust collection box, facilitating the collection of dust and debris on the table surface.

[0022] Optionally, a feed hole is provided on the dust collection box, and a plurality of material leakage holes are provided on the top plate, and the plurality of material leakage holes are arranged at intervals along the circumferential direction of the turntable.

[0023] By adopting the above technical solution, during the processing of the flange bearing seat, some dust and debris will enter the dust collection box through the material leakage holes on the top plate, and both the feed hole of the dust collection box and the material leakage holes of the top plate can accelerate the entry of dust and debris into the dust collection box, improving the cleaning speed.

[0024] In a second aspect, the present application provides a manufacturing method for producing a bearing seat from a flange, adopting the following technical solution: A manufacturing method for producing a bearing seat from a flange includes the following steps: S1. Place the to-be-processed flange bearing seat on the turntable, rotate the turntable, and the three clamping plates simultaneously move closer to the flange bearing seat. At this time, the surrounding plate can prevent the flange bearing seat from falling out of the workbench; S2. The rollers on the clamping plates first abut against the flange bearing seat. When the three clamping plates gradually clamp the flange bearing seat, the rollers gradually move into the receiving box. At this time, the flange bearing seat is fixed at the center position of the turntable; S3. After the tool to be processed finishes processing the flange bearing seat, rotate the driving gear, the driving gear drives the driven gear to rotate, thereby driving the threaded sleeve to rotate. When the threaded sleeve rotates, the connecting block is threadedly connected thereto, thereby pushing the surrounding plate upward. After the surrounding plate rises, the multiple air outlets clean the dust and debris on the workbench surface; S4. Raise the turntable, and a large amount of dust and debris on the workbench surface enter the dust collection box through the feed hole and the material leakage holes and are collected.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. First, place the flange bearing seat on the turntable, rotate the turntable, and at the same time the turntable drives the three clamping plates to move closer to the middle. The rollers on the clamping plates first abut against the flange bearing seat. When the three clamping plates clamp and fix the flange bearing seat, the rollers are retracted into the storage box, which can not only fix and clamp the flange bearing seat at the center position of the turntable, but also reduce the wear on the edge part of the flange bearing seat and the clamping plates; 2. After the flange bearing seat is processed, the sliding assembly drives the enclosure plate to rise, then the turntable is rotated in the reverse direction to drive the clamping plate away from the flange bearing seat. At this time, the turntable is raised again, and the air blowing ports on the enclosure plate clean the dust and garbage on the workbench surface. The dust and garbage enter the dust collection box through the feeding hole on the dust collection box and the material leakage hole on the top plate and are collected, which is convenient for keeping the workbench clean.

Detailed Description of the Embodiment

[0028] The following is a further detailed description of the present application in conjunction with the attached Figures 1 - 4 drawings.

[0029] The embodiment of the present application discloses a flange production bearing seat.

[0030] Referring to Figure 1 , a flange production bearing seat includes a workbench 1. The workbench 1 is horizontally arranged. The workbench 1 includes a top plate 11, side plates 12 and a bottom plate 13. The top plate 11 and the side plates 12, and the side plates 12 and the bottom plate 13 are fixedly connected. A turntable 2 is coaxially arranged on the workbench 1. The height of the turntable 2 is higher than the height of the top plate 11. Three sliding holes 111 are radially spaced apart on the top plate 11 along the turntable 2. The three sliding holes 111 are evenly distributed in an equilateral triangle. A clamping plate 3 is vertically arranged at each sliding hole 111. A connecting rod 31 is fixedly connected to the side of the clamping plate 3 facing away from each other. The connecting rod 31 passes through the sliding hole 111 and slides in the direction of approaching or separating from each other. Three enclosure plates 5 are vertically arranged outside the clamping plates 3 on the workbench 1 surface. The three enclosure plates 5 are circumferentially spaced apart along the top plate 11, and there is a gap between adjacent enclosure plates 5.

[0031] refer to Figure 2 and Figure 3 A dust box 8 is fixed at the bottom of the turntable 2, and a plurality of feeding holes 81 are spaced apart around the dust box 8. The diameter of the dust box 8 is larger than the diameter of the turntable 2. A plurality of leakage holes 112 are provided on the top plate 11 directly above the part where the diameter of the dust box 8 exceeds the turntable 2. The leakage holes 112 are spaced apart along the circumference of the turntable 2 to facilitate the dust and garbage on the workbench 1 to enter the dust box 8. A cylinder 82 is fixed at the bottom of the dust box 8, and a middle column 21 is fixed at the bottom of the cylinder 82. A first servo motor 22 is fixed at the bottom of the middle column 21, and the first servo motor 22 is fixed on the bottom plate 13. The first servo motor 22 drives the middle column 21 and the turntable 2 to rotate in both directions, and the rotation axis direction of the middle column 21 is along the vertical direction.

[0032] A turntable 4 is coaxially fixed on the center column 21, and three arc-shaped through holes 41 are spaced apart on the turntable 4. The through holes 41 are gradually opened from the center of the turntable 4 along the circumference of the turntable 4 to the edge of the turntable 4, and the positions of the through holes 41 correspond to the three splints 3 and the three connecting rods 31 respectively. The connecting rods 31 pass through the through holes 41 and slide back and forth along the length direction of the through holes 41.

[0033] refer to Figure 2 and Figure 4 The clamping plate 3 itself is provided with an arc, and the arcs all protrude toward the side of the clamping plate 3 that is away from each other. A plurality of rollers 32 are rotatably connected to the clamping plate 3. The plurality of rollers 32 are vertically arranged and spaced apart along the width direction of the clamping plate 3. The rotation axis direction of the rollers 32 is along the vertical direction. A accommodating box 33 is fixed to the side of the clamping plate 3 that is away from each other. The accommodating box 33 is fixed to the connecting rod 31. A rotating rod 321 is coaxially arranged on the rotating roller 32. The rotating roller 32 rotates relative to the rotating rod 321. A frame is fixed on the rotating rod 321. The frame is fixed to the spring 322, and telescopic rods 323 are respectively fixed on both sides of the spring 322. The telescopic rods 323 here are fixed. The rod 323 is a spring telescopic rod 323. The spring 322 and the telescopic rod 323 at one end away from the rotating rod 321 are fixed to the accommodating box 33. When the three clamps 3 gradually approach the flange bearing seat, the roller 32 first abuts against the flange bearing seat. At this time, the spring 322 and the telescopic rod 323 are gradually compressed until the clamp 3 completely clamps and fixes the flange bearing seat, and the roller 32 is completely recovered into the accommodating box 33. This not only reduces the wear on the flange bearing seat and the clamp 3, but also facilitates the flange bearing seat to move to the center of the turntable 4 faster, and does not affect the final clamping and fixation of the flange bearing seat by the clamp 3.

[0034] refer to Figure 2The starting height of the enclosure 5 is higher than the turntable 2, which is convenient for preventing the flange bearing seat from falling off the workbench 1 during processing. After the flange bearing seat is processed, the enclosure 5 is raised. A plurality of blowing ports 51 are opened on the side of the enclosure 5 facing the turntable 2. The plurality of blowing ports 51 are arranged at intervals along the width of the enclosure 5. Then the turntable 2 is raised, and the feed hole 81 of the dust box 8 is leaked out of the top plate 11. A sliding component 6 for driving the enclosure 5 to slide is arranged in the workbench 1.

[0035] The sliding assembly 6 includes a threaded sleeve 61, a connecting block 62 and a support rod 63. The threaded sleeve 61 is rotatably connected to the center column 21. The connecting block 62 is threadedly connected to the threaded sleeve 61. One end of the support rod 63 is fixed to the connecting block 62, and the other end is fixed to the enclosure 5. A driving assembly 7 is arranged in the workbench 1. The driving assembly 7 includes a driving tooth 71, a driven tooth 72 and a second servo motor 73. The second servo motor 73 is fixed to the bottom plate 13. The motor shaft of the second servo motor 73 is fixed to the driving tooth 71. The threaded sleeve 61 is fixed to the driven tooth 72. The driving tooth 71 and the driven tooth 72 are meshed; the enclosure 5 The interior is hollow, and a hair dryer 52 is fixedly connected to the bottom of the enclosure 5. The hair dryer 52 and the enclosure 5 are connected by a hose. The second servo motor 73 is started, driving the active gear 71 to rotate, and the active gear 71 is engaged with the driven gear 72, thereby driving the threaded sleeve 61 to rotate. When the threaded sleeve 61 rotates, the connecting block 62 is threadedly connected to the threaded sleeve 61, and the connecting block 62 moves in the vertical direction under the limiting and guiding action of the support rod 63 and the enclosure 5, thereby driving the enclosure 5 to move upward. When the enclosure 5 needs to be lowered, it only needs to reversely start the second servo motor 73 to achieve the lowering of the enclosure 5.

[0036] The implementation principle of a flange bearing seat production embodiment of the present application is: first place the flange bearing seat to be processed on the turntable 2, rotate the turntable 2, and at the same time, the three clamps 3 move synchronously to the middle position, and the roller 32 on the clamp 3 first abuts against the flange bearing seat, and is gradually recovered into the receiving box 33. When the three clamps 3 completely clamp and fix the flange bearing seat, the roller 32 completely enters the receiving box 33, and the flange bearing seat is located at the center of the turntable 2 at this time. In addition, after the flange bearing seat is processed, the enclosure 5 and the turntable 2 are raised, and the dust and garbage on the table are collected in the dust box 8 to keep the table clean.

[0037] The embodiment of the present application also discloses a method for manufacturing a flange bearing seat.

[0038] The following steps are involved: S1. Place the flange bearing seat to be processed on the turntable 2, rotate the turntable 2, and the three clamping plates 3 are simultaneously moved closer to the flange bearing seat. At this time, the enclosure plate 5 can prevent the flange bearing seat from falling off the workbench 1; S2. The roller 32 on the clamping plate 3 first abuts against the flange bearing seat. When the three clamping plates 3 gradually clamp the flange bearing seat, the roller 32 gradually moves into the receiving box 33. At this time, the flange bearing seat is fixed at the center position of the turntable 4; S3. After the tool to be processed finishes machining the flange bearing seat, rotate the driving gear 71. The driving gear 71 drives the driven gear 72 to rotate, thereby driving the threaded sleeve 61 to rotate. When the threaded sleeve 61 rotates, the connecting block 62 is threadedly connected thereto, thereby pushing the surrounding plate 5 upward. After the surrounding plate 5 rises, the plurality of air blowing ports 51 clean the dust and debris on the table surface of the workbench 1; S4. Raise the turntable 2. A large amount of dust and debris on the table surface of the workbench 1 enter the dust collection box 8 through the feed hole 81 and the leakage hole 112 and are collected.
