Description

Technical Field

[0001] The invention relates to the technical field of turning equipment, and more specifically to a device and process for processing pocket holes of a spherical iron self-aligning roller cage. Background Art

[0002] Ductile iron spherical roller is a rolling bearing element made of ductile iron material. It has the characteristics of self-alignment, impact and vibration resistance, wear resistance, corrosion resistance and low noise. It is widely used in spherical roller bearings, tapered roller bearings and spherical roller bearings. Ductile iron spherical roller cage is a component used to evenly distribute ductile iron spherical rollers and keep them in the correct position in the bearing. The spherical rollers are separated by pockets evenly arranged on the cage that are compatible with the spherical rollers. It plays the role of maintaining the roller spacing, preventing the rollers from falling off, guiding the roller movement and reducing noise for the ductile iron spherical rollers in the bearing, so as to ensure the normal operation and service life of the bearing.

[0003] In the related art, a turning device is generally used to process the pockets of ductile iron spherical roller cages. When processing an extra-large ductile iron spherical roller cage, since both the top and the bottom need to be processed, when using a traditional turning device, after completing the processing of one side, the cage needs to be flipped. Since the traditional turning device needs to maintain sufficient processing operation space and needs to adapt to different types of processing workpieces, it is not suitable to add a special matching flipping mechanism on the basis of the original structure. Therefore, the flipping operation of the cage is generally completed with the help of external lifting equipment and manual cooperation. Due to the size and gravity of the cage, this flipping method is difficult to operate and takes a long time. During the flipping process, the lifting equipment and manual cooperation are required, which is difficult to be applied to the batch processing environment of extra-large ductile iron spherical roller cages. Therefore, there is an urgent need for a pocket processing device with an automatic flipping function that does not affect the processing operation space and is suitable for batch processing of extra-large ductile iron spherical roller cages.

DETAILED DESCRIPTION

[0018] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples. Embodiment 1

[0019] Please refer to Figures 1 to 3 The first aspect of the present invention discloses a ductile iron spherical roller cage pocket processing device, comprising: a base 1, a turning mechanism 2, a clamping mechanism 3 and a flipping mechanism 4, the turning mechanism 2 comprises a beam assembly 21 with a flipping function, a turning assembly 22 for turning pockets on a cage 5 and two support beam assemblies 23 with linear displacement functions, the turning assembly 22 and the flipping mechanism 4 are respectively arranged on two different sides of the beam assembly 21, the two ends of the beam assembly 21 are respectively connected to the tops of the two support beam assemblies 23, the bottom of the support beam assembly 23 is slidably connected to the top of the base 1, the turning assembly 22 is provided with a translation mechanism, which can make it translate along the beam assembly 21, and the support beam assembly 23 is provided with a power mechanism, which can make the entire turning mechanism 2 translate on the top of the base 1. Since they all belong to the prior art, the specific structures of the turning assembly 22 and the support beam assembly 23 are not disclosed here.

[0020] The clamping mechanism 3 includes a clamp 31 for clamping and fixing the retaining frame 5, a rotating platform 32 with a rotating function, and two locking components 33. The clamp 31 and the rotating platform 32 can be detachably assembled together. The locking component 33 is used to lock the assembled clamp 31 and the rotating platform 32. The locking component 33 includes a locking member and an unlocking member. The locking member is arranged on the rotating platform 32. The rotating platform 32 is installed on the top of the base 1. The rotating platform 32 is driven to rotate by a driving source. Since it belongs to the prior art, the specific structure is not disclosed here.

[0021] The flipping mechanism 4 includes a two-way telescopic component 41 and a flipping driving component 42 of the same number as the locking component 33. The fixed end of the two-way telescopic component 41 is connected to one side of the beam component 21. The two-way telescopic component 41 can be a two-way cylinder. The two flipping driving components 42 are respectively fixedly connected to the two telescopic ends of the two-way telescopic component 41. The unlocking part is correspondingly installed on the flipping driving component 42. The two-way telescopic component 41 drives the flipping driving component 42 to dock with the outer side of the clamp 31, so that the unlocking part triggers the corresponding locking component to release the locking effect of the clamp 31. The clamp 31 and the retaining frame 5 are driven to move up and flip at a preset angle through the flipping driving component 42.

[0022] It should be noted that when the above-mentioned processing device performs pocket hole processing on the retaining frame 5, the retaining frame 5 is first placed on the top surface of the rotating platform 32, and the middle part of the outer ring surface of the retaining frame 5 is squeezed and fixed by the clamp 31. After that, the support beam assembly 23 is translated on the top of the base 1, driving the crossbeam assembly 21 and the turning assembly 22 to move together until the turning assembly 22 reaches the processing position of the retaining frame 5, and then the pocket hole processing is performed on the retaining frame 5 by the turning assembly 22; and after the top surface processing of the retaining frame 5 is completed, the retaining frame 5 needs to be turned over and the pocket hole processing is performed on the other side. At this time, the turning assembly 22 can be driven to turn upward away from the retaining frame 5 by the rotation of the crossbeam assembly 21, and the turning mechanism 4 is synchronously turned downward close to the retaining frame 5. After the turning mechanism 4 rotates to the position aligned with the clamp 31, the crossbeam assembly 21 stops rotating (the state of the turning mechanism 4 after switching can be referred to in the attached Fig.12), the two flip driving components 42 are driven by the bidirectional telescopic component 41 to move simultaneously close to the outside of the clamp 31. During the docking process between the bottom end of the flip driving component 42 and the outside of the clamp 31, the unlocking piece follows the flip driving component 42 to move close to the locking piece. After the flip driving component 42 is completely docked with the clamp 31, the unlocking piece triggers the locking piece to release the locking effect of the clamp 31. After that, the two flip driving components 42 are driven together to first drive the clamp 31 and the retaining frame 5 to move up to a preset height. The preset height is at least greater than the diameter of the clamp 31, so that the clamp 31 can have a suitable flipping space, and then the flip driving component 42 drives the clamp 31 and the retaining frame 5 to flip 180 degrees together. , and then the flip driving assembly 42 drives the clamp 31 and the retaining frame 5 to move downward together, so that the clamp 31 is assembled with the rotating platform 32 again, and the bottom of the retaining frame 5 is in contact with the top surface of the rotating platform 32. The two flip driving assemblies 42 are driven by the two-way telescopic assembly 41 to translate and separate from the two sides of the clamp 31, and the unlocking part follows the flip driving assembly 42 to move and separate from the locking part, so that the locking part locks the clamp 31 again, completing the flipping operation of the retaining frame 5, and then the crossbeam assembly 21 is rotated to make the turning assembly 22 flip down and reset, and the flip mechanism 4 flips upward and reset synchronously, and then the turning assembly 22 is used to process the pocket on the other side of the retaining frame 5, and the retaining frame 5 can be taken out after the processing is completed.

[0023] In this way, the present invention can realize the function of fast and automatic flipping of the retaining frame 5 by setting the flipping mechanism 4 for use in conjunction with the assembled clamping mechanism 3, wherein, by setting the flipping mechanism 4 and the turning component 22 at different side positions of the beam component 21, when the turning component 22 is processed, the flipping mechanism 4 is located above the base 1, and will not occupy the activity space of the base 1, nor will it interfere with the processing of the turning component 22. When the retaining frame 5 needs to be flipped, the position of the flipping mechanism 4 and the turning component 22 can be swapped by rotating the beam component 21, so that the flipping mechanism 4 can drive the clamp 31 and the retaining frame 5 to flip together, without the assistance of external lifting equipment or manual coordination, thereby reducing the difficulty of flipping the retaining frame 5 and accelerating the flipping speed, and can be well applied to the batch processing scenario of extra-large ductile iron spherical roller retaining frames 5.

[0024] Please refer to Figures 4 to 6The locking member includes a plug connector 331, a card body 332 and a support spring 333. The plug connector 331 is fixedly installed at the bottom of the clamp 31. A plug slot 334 is provided inside the clamp 31. The card body 332 is slidably installed in the plug slot 334. The support spring 333 is fixedly installed between the card body 332 and the inner wall of the plug slot 334. The bottom end of the plug connector 331 is slidably inserted in the plug slot 334. The card body 332 is slidably engaged with one side of the plug connector 331. A first inclined groove body 335 is provided on one side of the card body 332. The unlocking member is a contact plate 336 with an inclined surface at one end matching the first inclined groove body 335.

[0025] The first and second clamping portions 332 and 333 of the clamp 31 are locked together, and the first and second clamping portions 332 are locked together. After the flipping is completed, the plug connector 331 follows the clamp 31 to move down and is assembled with the top of the rotating platform 32 again and is synchronously plugged into the plug slot 334. After the flipping driving component 42 is separated from the clamp 31, the contact plate 336 is separated from the first inclined groove, and the clamping body 332 is reset under the elastic force of the support spring 333 and is clamped with the plug connector 331 again; in this way, the locking component 33 is used in conjunction with the flipping driving component 42 to realize the synchronous adaptive switching function of the use state of the flipping driving component 42 and the use state of the locking component 33, so that the flipping driving component 42 and the clamp 31 are docked, the clamp 31 is unlocked, the flipping driving component 42 is separated from the clamp 31, and the clamp 31 is locked. The actions are carried out in an orderly manner without the need for manual active control switching or setting of program collaborative control, which is very convenient to use.

[0026] Please refer to Figure 7 The clamp 31 includes a supporting ring body 311, four identical linear telescopic members 312 and a clamping plate 313. The supporting ring body 311 is located at the top of the rotating platform 32. The four linear telescopic members 312 are evenly distributed on the outer ring surface of the supporting ring body 311. The linear telescopic member 312 can be a cylinder. The four clamping plates 313 are evenly distributed on the inner side of the supporting ring body 311. The telescopic ends of the four linear telescopic members 312 are fixedly connected to one side of the four clamping plates 313. The inner side of the clamping plate 313 is provided with a protective layer of rubber material.

[0027] It should be noted that when the above-mentioned clamp 31 clamps and fixes the retaining frame 5, after the retaining frame 5 is placed on the top surface of the rotating platform 32, the four linear telescopic members 312 are extended at the same time, which can drive the four clamping plates 313 to synchronously approach the outer ring surface of the retaining frame 5. Under the joint pushing action of the four clamping plates 313, if the retaining frame 5 is not in the standard installation position, the retaining frame 5 can be pushed to the standard position. When the retaining frame 5 is no longer pushed, the retaining frame 5 remains in a fixed state.

[0028] Please refer to Figure 7 The flip driving component 42 includes a fixed frame 421, a linear lifting member, a docking member and a flip driving member. The fixed frame 421 is fixedly connected to the telescopic end of the two-way telescopic component 41. The top of the fixed frame 421 is slidably connected to one side of the beam assembly 21. The docking member is slidably installed on the fixed frame 421, which is used to cooperate with the outer side of the clamp 31. The linear lifting member and the flip driving member are both connected to the docking member. The unlocking member is installed on one side of the fixed frame 421. The two fixed frames 421 are driven to approach the two sides of the clamp 31 through the two-way telescopic component 41, so that the docking member docks with the outer side of the clamp 31. The unlocking member triggers the locking member to unlock the clamp 31, and the docking member and the retaining frame 5 are driven to move up together through the linear lifting member. After the retaining frame 5 reaches a preset height, the flip driving member drives the docking member and the retaining frame 5 to flip together at a preset angle.

[0029] For details, please refer to Figures 8 to 9The docking parts include a sliding seat 422 and a docking head 423. A sliding groove 424 is provided on one side of the fixed frame 421. The outer side of the sliding seat 422 is slidably connected to the inner side of the sliding groove 424. The docking head 423 is rotatably installed on one side of the sliding seat 422. A matching shaft 425 adapted to the docking head 423 is fixedly installed on the outer side of the clamp 31. The flip driving member includes a matching gear 426 and a mounting shell 427. The matching gear 426 is fixedly sleeved on the outer side of the docking head 423. The mounting shell 427 is fixedly mounted on the upper end of the fixed frame 421. A plurality of tooth blocks 428 that are compatible with the matching gear 426 are linearly and equidistantly mounted on the inner side of the mounting shell 427. A torsion spring 429 is mounted between the rotating end of the tooth block 428 and the inner wall of the mounting shell 427. A limiting groove 4210 is provided at one end of the tooth block 428 close to the torsion spring 429. A plurality of limiting blocks 4211 corresponding to the tooth blocks 428 are fixedly mounted on one side of the inner wall of the mounting shell 427 close to the limiting groove 4210. One end of the limiting block 4211 contacts the upper end of the inner wall of the corresponding limiting groove 4210. The linear lifting component includes a driving motor 4212 and a transmission screw 4213. The driving motor 4212 is fixedly installed on the top of the fixed frame 421. The bottom end of the transmission screw 4213 is rotatably connected to the inner bottom wall of the slide groove 424, and its top end is fixedly connected to the driving end of the driving motor 4212. The sliding seat 422 is threadedly mounted on the outer side of the transmission screw 4213.

[0030] It should be noted that when the above-mentioned flip driving assembly 42 is in use, the flip driving assembly 42 is aligned with the clamp 31 under the rotation of the cross beam assembly 21. At this time, the docking joint 423 and the matching shaft 425 are kept aligned. Then, through the contraction of the two-way telescopic assembly 41, the two fixed frames 421 can be driven to move close to the clamp 31 at the same time. After the docking joint 423 is docked with the corresponding matching shaft 425, the flip driving assembly 42 is successfully docked with the clamp 31. At this time, the clamp 31 has also been unlocked, and the transmission screw 4213 can be driven to rotate synchronously by driving the motor 4212 forward. The sliding seat 422 is driven by the transmission screw 4213 Under the action, it starts to move up along the slide groove 424, and the docking head 423 and the matching gear 426 move up together with the sliding seat 422, and the clamp 31 and the retaining frame 5 move up together under the joint driving action of the two docking heads 423. When the matching gear 426 meshes with the lowermost tooth block 428, the tooth block 428 is pushed upward by the matching gear 426, and the tooth block 428 cannot rotate upward under the cooperation and restriction of the limiting groove body 4210 and the limiting block 4211. Therefore, during the upward movement of the matching gear 426, the tooth block 428 will not rotate, but drive the matching gear 426 to rotate, and the docking head 423 follows the matching gear When the mating gear 426 is in contact with the tooth block 428 at the top, the tooth block 428 generates a downward thrust, causing the tooth block 428 to start to rotate downward, and the torsion spring 429 is synchronously tightened under the rotation of the tooth block 428, so that when the mating gear 426 moves downward, the tooth block 428 is in contact with the tooth block 428 at the top, and the torsion spring 429 is synchronously tightened under the rotation of the tooth block 428, so that when the mating gear 426 moves downward, the tooth block 428 is in contact with the tooth block 428 at the top, and the torsion spring 429 is synchronously tightened under the rotation of the tooth block 428, so that when the mating gear 426 moves downward, the tooth block 428 is in contact with the tooth block 428 at the top, and the torsion spring 429 is synchronously tightened under the rotation of the tooth block 428, so when the mating gear 426 moves downward, the torsion spring 429 is synchronously tightened. The tooth block 428 will not generate a rotational driving force on the mating gear 426, so that the mating gear 426 will not rotate during the downward movement. When the mating gear 426 is separated from the tooth block 428, the tooth block 428 can be driven to rotate and reset under the elastic force of the torsion spring 429 until the sliding seat 422 slides to the bottom of the slide groove 424, so that the clamp 31 is assembled with the rotating platform 32 again. In this way, the flipping action of the retaining frame 5 is completed by driving the flipping driving component 42. The flipping process is completed during the upward movement of the retaining frame 5. There is no need to rely on external lifting equipment and manual coordinated operations, and the retaining frame 5 can be quickly flipped.

[0031] Please refer to Figure 8 , Fig.10 and Fig.11The docking parts also include an extrusion plate 4214, a clamping shaft 4215 and a return spring 4216. The extrusion plate 4214 is fixedly installed on the upper end of the inner wall of the slide groove 424. The bottom end of the extrusion plate 4214 is provided with an extrusion inclined surface. The clamping shaft 4215 is slidably installed in the sliding seat 422. The return spring 4216 is fixedly installed between the clamping shaft 4215 and the sliding seat 422. One side of the clamping shaft 4215 is provided with a second inclined surface groove body 4217 adapted to the extrusion inclined surface. One side of the matching gear 426 is provided with a matching clamping hole 4218. One end of the clamping shaft 4215 is slidably clamped with the matching clamping hole 4218.

[0032] It should be noted that before the mating gear 426 comes into contact with the tooth block 428, the mating gear 426 can be locked by engaging the engaging shaft 4215 with the engaging hole 4218 on the mating gear 426, so that it cannot rotate, and the docking head 423 cannot rotate either. In this way, the clamp 31 and the retaining frame 5 will not rotate relative to each other before moving up to the flip position, but will maintain a horizontal and stable state, thereby improving the stability of the retaining frame 5. Before the mating gear 426 meshes with the lowermost tooth block 428, the bottom end of the extrusion plate 4214 first contacts the second inclined groove 4217 on the engaging shaft 4215. As the sliding seat 422 continues to move upward, the engaging shaft 4215 is squeezed by the extrusion plate 4214 and begins to shrink toward the inside of the sliding seat 422 and gradually moves away from the engaging hole 4218. The return spring 4216 is squeezed by the engaging shaft 421 4218, and the mating gear 426 is locked again, so that the clamp 31 and the retaining frame 5 remain stable when they move downward, so as to ensure that the clamp 31 can be smoothly assembled with the rotating platform 32.

[0033] Please refer to Figure 2 The crossbeam assembly 21 includes a rotating motor 211 and a crossbeam 212. The two ends of the crossbeam 212 are rotatably connected to the two support beam assemblies 23 respectively. The rotating motor 211 is fixedly installed on one side of one of the support beam assemblies 23. The rotating end of the rotating motor 211 is fixedly connected to one end of the crossbeam 212.

[0034] It should be noted that when the flipping mechanism 4 and the turning assembly 22 need to be swapped, the motor 211 can be rotated to drive the beam 212, the turning assembly 22 and the flipping mechanism 4 to rotate together. After the beam 212 rotates ninety degrees, the flipping mechanism 4 moves to the position of the turning assembly 22. Embodiment 2

[0035] like Fig.13 As shown, when the above-mentioned processing device is used to process the pockets using the existing process, the processing method is: first use the hollow drill 6 to perform roughing treatment on the retaining frame 5 with a hole diameter of a and a roughing reserve of b, and then use the forming boring tool 7 for one fine boring. However, the problem with this processing technology is that since the pocket shape of the retaining frame 5 is large at the upper end and small at the lower end, forming a funnel shape, the hollow drill 6 can only select the tool according to the size of the lower end of the pocket, and the roughing reserve at the upper end is much larger than the roughing reserve at the lower end, which will not only lead to a large processing amount of the forming tool and severe tool wear, but also affect the dimensional accuracy of the pocket, resulting in a short tool life, and due to the small feed rate, the overall processing efficiency is low. Based on this, the present invention also provides a processing technology for the pockets of a ductile iron spherical roller retainer, which can be applied to the above-mentioned ductile iron spherical roller retainer pocket processing device, and includes the following operating steps: S1, placing the retainer 5 on the workstation to be processed, and squeezing and fixing the middle part of the outer ring surface of the retainer 5; S2, using a plunge milling cutter 9 to perform step roughing with a roughing hole diameter c according to the shape of the pocket hole, controlling the roughing allowance d at the upper and lower ends to be controlled at 0.5 mm, and processing to form a preliminary pocket hole; S3, after completing one preliminary pocket hole processing, the cage 5 is driven to rotate so that the next pocket hole to be processed of the cage 5 reaches the preset processing station, and the operation is repeated until all the preliminary pocket holes on the top surface of the cage 5 are processed; S4, replacing the forming boring tool 7, and performing fine boring processing on the preliminary pocket holes in sequence, removing the roughing allowance, and obtaining the forming pocket holes 8 of the required size, and repeating the operation until all the preliminary pocket holes are processed into the forming pocket holes 8; S5, lifting the holder 5 in the fixed state to move it away from the processing station, and after the holder 5 rises to a preset height, driving the holder 5 to flip 180 degrees, so that the bottom of the holder 5 turns upward, and then driving the holder 5 to move down and reset to the processing station; S6. Repeat the above-mentioned S2-S4 operations to complete the forming pocket 8 processing on the other side of the retainer 5.

[0036] It should be noted that if Fig.14As shown, the improved pocket hole processing technology mentioned above is used, which uses a plunge milling cutter 9 for roughing. Since the tool diameter of the plunge milling cutter 9 is smaller than the minimum size of the pocket hole opening, step roughing can be performed according to the shape of the pocket hole, and the roughing allowance at the upper and lower ends is controlled to be about 0.5 mm, so that the tool wear is small and the service life of the tool can be extended. At the same time, the plunge milling cutter 9 leaves a very small machining allowance for fine boring after roughing, and then the forming boring cutter 7 is used to process to the finished product size. Due to the small amount of fine boring, the overall machining efficiency is significantly improved compared with the existing machining technology.

[0037] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
