Description

Technical Field

[0001] This invention relates to the field of bearing outer ring press-fitting technology, specifically to a ball bearing outer ring press-fitting device. Background Technology

[0002] There are two main methods for pressing bearing outer rings: automatic pressing and manual pressing. Manual pressing is inefficient and poses an accidental danger to the operator, while automatic pressing equipment is expensive and it is inconvenient to assist in positioning the bearing outer ring during the pressing process. Therefore, manually feeding the bearing outer ring and then automatically pressing it with a press is a new pressing method for pressing bearing outer rings.

[0003] The manual loading of the bearing outer ring requires visual alignment, which is difficult. If the bearing outer ring is placed crookedly, the bearing outer ring will be subjected to uneven force during pressing, which may cause it to be crooked or even damaged, affecting the quality of the bearing outer ring pressing. To address this, we propose a ball-positioning bearing outer ring pressing device. Summary of the Invention

Each sector plate 202 is connected to a mounting plate 203 through a guide assembly. The mounting plate 203 has a mounting hole 204. A positioning rod 205 is installed inside the mounting hole 204 by means of a thread. The positioning rod 205 is provided with a ball limiting assembly for limiting the lower end of the outer ring after alignment and positioning. The positioning disk 201 is provided with a lifting assembly for raising and lowering each set of mounting plates 203.

[0035] A movable component is provided on the press machine 101 for movable connection to the support platform 102, and a cleaning component is provided on the support platform 102 for cleaning the lower end of the positioning plate 201.

[0036] It should be noted that during the press-fitting of the bearing outer ring, the press-fitting operation is completed through the cooperation of the alignment and positioning components, the ball limit components, the lifting components, and the adjustment components. The entire press-fitting process can quickly align, position, and limit the bearing outer ring, and also automatically push and press the bearing outer ring, ensuring the quality of the press-fitting of the bearing outer ring while improving the press-fitting efficiency.

[0037] Preferably, the bead limiting assembly includes a mounting cavity 301 disposed inside the positioning rod 205, a mounting groove 302 for mounting the bead body 303 is provided between the mounting cavity 301 and the outer side of the positioning rod 205, and a compression spring 304 for pressing and pushing the bead body 303 is disposed inside the mounting cavity 301.

[0039] Preferably, the guide assembly includes a guide groove 401 formed on the sector plate 202, a mounting plate 203 located inside the guide groove 401, and a plurality of round rods 402 slidably connected on the mounting plate 203, the round rods 402 being fixed inside the guide groove 401;

[0040] It should be noted here that the guide groove 401 and the round rod 402 facilitate the guiding of the lifting and lowering movement of the mounting plate 203.

[0041] Preferably, the lifting assembly includes a lifting plate 501 disposed below the positioning plate 201. The lifting plate 501 is located inside each group of sector plates 202. A threaded sleeve 502 is fixed on the lifting plate 501. A threaded rod 503 is threadedly engaged with the threaded sleeve 502. One end of the threaded rod 503 is rotatably connected to the lower end of the positioning plate 201. A drive pin 504 is fixed to the other end of the threaded rod 503. A telescopic assembly for assisting telescopic connection is provided between the lifting plate 501 and the mounting plate 203.

[0042] It should be noted here that: the threaded rod 503 is driven to rotate by the drive pin 504. During the rotation of the threaded rod 503, the lifting plate 501 is subjected to force and moves up and down through the meshing transmission between the threaded rod 503 and the threaded sleeve 502. During the up and down movement of the lifting plate 501, the connecting action of the telescopic component drives the lifting of each set of mounting plates 203 and the positioning rods 205 on the mounting plates 203. By adjusting the lifting of each set of positioning rods 205, the position of the glass ball body 303 on the positioning rod 205 can be adjusted. The adjustment of the position facilitates the limit operation after the bearing outer ring of different thicknesses is aligned and positioned.

[0043] Preferably, the telescopic assembly includes a sleeve 601 fixed to the outside of the lifting plate 501, a slide rod 602 slidably connected to the sleeve 601, and one end of the slide rod 602 being fixed to one side of the mounting plate 203.

[0044] It should be noted that the sleeve 601 and the slide rod 602 facilitate the telescopic connection between the auxiliary lifting plate 501 and the mounting plate 203, and the sleeve 601 and the slide rod 602 facilitate the synchronous lifting and lowering of the mounting plate 203 while the lifting plate 501 is lifting.

[0045] Preferably, the sliding assembly includes a sliding groove 701 formed on the positioning plate 201, a sliding block 702 slidably connected to the sliding groove 701, and one end of the sliding block 702 fixed to the upper end of the sector plate 202; the adjusting assembly includes a threaded cylinder 801 sleeved on the outside of the pressure head 104, the threaded cylinder 801 being threadedly engaged with the outside of the pressure head 104, a drive ring 802 for driving the threaded cylinder 801 being fixed at the upper end of the threaded cylinder 801, a transmission ring 803 being connected to the lower end of the threaded cylinder 801 through a rotating assembly, a connecting rod 804 being provided between the transmission ring 803 and the sliding block 702, and the two ends of the connecting rod 804 being rotatably connected to the outer sides of the sliding block 702 and the transmission ring 803, respectively;

[0046] It should be noted that: the threaded cylinder 801 is driven to rotate by the drive ring 802. During the rotation of the threaded cylinder 801, the threaded engagement transmission between the threaded cylinder 801 and the outer side of the pressure head 104, as well as the connection of the rotating components, causes the threaded cylinder 801 and the drive ring 803 to move up and down on the outer side of the pressure head 104. During the up and down movement of the drive ring 803, the connection transmission of each set of connecting rods 804 and the sliding connection between the sliding groove 701 and the sliding block 702 cause each set of sliding blocks 702 and the sector plate 202 to move closer or further apart under force, adjusting the distance between each set of sector plates 202. By adjusting the distance, it is convenient for each set of sector plates 202 to perform alignment and positioning operations for bearing outer rings with different bore diameters.

[0047] Preferably, the rotating assembly includes an annular groove 901 formed at the end of the threaded cylinder 801, and an annular plate 902 is rotatably connected inside the annular groove 901. The annular plate 902 is fixed to the upper end of the transmission ring 803.

[0048] It should be noted that the annular groove 901 and the annular plate 902 facilitate the rotatable connection between the transmission ring 803 and the threaded cylinder 801, and the annular groove 901 and the annular plate 902 facilitate the lifting and lowering of the transmission ring 803 while the threaded cylinder 801 is being upgraded.

[0049] Preferably, the moving component includes a slide rail 1001 disposed between the press machine 101 and the support platform 102 for assisting the sliding of the support platform 102, and a push cylinder 1002 installed on the press machine 101 for pushing the support platform 102.

[0050] It should be noted that the sliding connection of the slide rail 1001 and the pushing action of the push cylinder 1002 facilitate the movement of the auxiliary support platform 102.

[0051] Preferably, the cleaning component includes a mounting cylinder 1101 fixed to the upper end of the support platform 102, and an annular cleaning pad 1103 for abutting against the lower end of the positioning plate 201 is mounted on the upper end of the mounting cylinder 1101 through an annular inner groove 1102.

[0052] It should be noted that when the lower end of the positioning plate 201 needs to be cleaned, the support platform 102 is moved by the moving component. By moving, the mounting cylinder 1101 is positioned below the pressure head 104. At this time, the lifting cylinder 105 drives the pressure head 104 to descend and make the positioning plate 201 abut against the annular cleaning pad 1103 to clean the positioning surface of the positioning plate 201.

[0053] In this solution: a ball bearing outer ring press-fitting device includes the following steps:

[0054] During the press-fitting operation of the bearing outer ring, the bearing outer ring is pushed towards the lower end of the positioning plate 201 and abuts against it. During this pushing process, the inner side of the bearing outer ring is fitted against the outer side of each set of sector plates 202. Through the abutting action between the upper end of the bearing outer ring and the lower end of the positioning plate 201, the bearing outer ring to be press-fitted is aligned and positioned. During the positioning and pushing process of the bearing outer ring towards the positioning plate 201, the inner ring of the bearing outer ring first abuts against the glass ball body 303 at the front end of the positioning rod 205 on each set of mounting plates 203. During this abutting process, through the abutting action between the inner side of the bearing outer ring and the glass ball body 303, the glass ball body 303 is pushed towards the interior of the mounting cavity 301. After the bearing outer ring is aligned and positioned, the abutting action of the compression spring 304 on the glass ball body 303 causes the glass ball body 303 to reset and abut against the lower end of the aligned and positioned bearing outer ring (see...). Figure 11 (In the state of the bearing), the outer ring of the bearing after alignment and positioning is limited. After the alignment, positioning and limiting operation of the outer ring of the bearing, the lifting cylinder 105 pushes the pressure head 104 toward the workpiece placed on the support table 102. During the movement, the positioning plate 201 pushes the outer ring of the bearing, pressing the outer ring of the bearing into the inside of the workpiece, thus completing the pressing operation of the outer ring of the bearing. The entire pressing process can quickly align, position and limit the outer ring of the bearing, and automatically push and press the outer ring of the bearing, ensuring the pressing quality of the outer ring of the bearing while improving the pressing efficiency. After the outer ring of the bearing is pressed, the lifting cylinder 105 drives the pressure head 104 and the positioning plate 201 to reset. During the reset process, the glass ball body 303 and the inner side of the outer ring of the bearing pull and contract, causing each group of sector plates 202 to separate from the pressed outer ring of the bearing.

[0055] During the press-fitting of the bearing outer ring, the threaded cylinder 801 is driven to rotate by the drive ring 802. During the rotation of the threaded cylinder 801, the threaded engagement transmission between the threaded cylinder 801 and the outer side of the press head 104 and the connection of the rotating components cause the threaded cylinder 801 and the drive ring 803 to move up and down on the outer side of the press head 104. During the up and down movement of the drive ring 803, the connection transmission of each set of connecting rods 804 and the sliding connection between the sliding groove 701 and the sliding block 702 cause each set of sliding blocks 702 and the sector plate 202 to move closer or further apart under force, adjusting the distance between each set of sector plates 202. By adjusting the distance, it is convenient for each set of sector plates 202 to perform alignment and positioning operations for bearing outer rings with different bore diameters.

[0056] Furthermore, during the press-fitting of the bearing outer ring, the threaded rod 503 is driven to rotate by the drive pin 504. During the rotation of the threaded rod 503, the lifting plate 501 is subjected to force and moves up and down through the meshing transmission between the threaded rod 503 and the threaded sleeve 502. During the up and down movement of the lifting plate 501, the connecting action of the telescopic component drives the lifting of each set of mounting plates 203 and the positioning rods 205 on the mounting plates 203. By adjusting the lifting of each set of positioning rods 205, the position of the glass ball body 303 on the positioning rod 205 can be adjusted. The adjustment of the position facilitates the limit operation after the bearing outer ring of different thicknesses is aligned and positioned.
