Description

Technical Field

[0001] This invention relates to the field of bearing assembly technology, and in particular to a fully automatic assembly machine for spherical roller bearing housings. Background Technology

[0002] Spherical roller bearings, also known as outer spherical bearings, belong to the deep groove ball bearing family. Their key feature is a spherical outer ring surface, which fits into the corresponding concave spherical surface of the bearing housing for self-aligning. Each spherical roller bearing is not used individually; it must be assembled into a housing for overall machine operation. The process of assembling spherical roller bearings into the housing is not as simple as it seems, requiring many complex steps. Currently, there is no automated equipment available for this assembly work, and many steps still need to be performed manually. Furthermore, due to the high labor intensity of these assembly tasks, inconsistent quality is easily generated, leading to a high defect rate in the assembled products. This reliance on manual assembly also reduces the overall efficiency of the production line.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art.

[0039] refer to Figure 1-12This invention provides a fully automatic spherical roller bearing seat assembly machine, including a feeding mechanism 1 and a discharging mechanism 2 arranged sequentially along the material inlet direction; a pre-pushing mechanism 3 and a skid mechanism 4 are provided between the feeding mechanism 1 and the discharging mechanism 2 (here, the feeding mechanism 1 and the discharging mechanism 2 refer to the sequence of assembly operations along the material inlet direction, that is, the pre-pushing mechanism 3 is located downstream of the feeding mechanism 1, and the skid mechanism 4 is located downstream of the pre-pushing mechanism 3 and upstream of the discharging mechanism 2); it also includes a controller (such as a PLC controller), the feeding mechanism 1, the discharging mechanism 2, and the pre-pushing mechanism 4. Both mechanism 3 and the skid mechanism are electrically connected to the controller. Both the pre-push mechanism 3 and the skid mechanism 4 include a workpiece fixing device 53. The workpiece fixing device 53 is used to fix the workpiece (i.e., the bearing with a seat) during assembly. There can be one or multiple workpiece fixing devices 53. The workpiece fixing device 53 includes a pressure plate and a power (such as a cylinder or hydraulic cylinder) to drive the pressure plate to move towards the first fixed position 501 / second fixed position 510. The power drives the pressure plate to move above the first fixed position 501 / second fixed position 510, thereby fixing the workpiece in the fixed position and preventing it from shaking. The pre-push mechanism 3 includes a first drive source 30, a push rod 31 and a first assembly table 50. The first assembly table 50 is provided with the first fixed position 501. The first drive source 30 can drive the push rod 31 to move towards the first fixed position 501. The skid mechanism 4 includes a drive device, a pry bar 42 and a second assembly table 51. The second assembly table 51 is provided with the second fixed position 510. The drive device can drive the pry bar 42 to move towards the second fixed position 510. like Figure 8 As shown, the first assembly station 50 and the second assembly station 51 can be multiple integrated units.

[0040] The fully automatic spherical roller bearing housing assembly machine provided by this invention operates as follows: During assembly, the feeding mechanism 1 feeds the spherical roller bearing (hereinafter referred to as: bearing) and the bearing housing (mainly square bearing housing / rhomboid bearing housing). The bearing can be pre-positioned in a certain posture within the bearing housing to form a mounted bearing. At this time, both ends of the bearing protrude from the bearing housing (i.e.,...) Figure 10 In the first state of assembly, the bearing is placed on the first fixed position 501, and the two ends of the bearing housing are fixed by the workpiece fixing device 53 to prevent the bearing housing from shifting during assembly. At this time, the first drive source 30 (such as a cylinder) drives the push rod 31 to move towards the first fixed position 501, so that the push rod 31 contacts the bearing and forms a thrust on the bearing. The push rod 31 pushes the part of the bearing that protrudes from the bearing housing, so that the bearing has a certain angle of inclination within the bearing housing (i.e., Figure 11The second state in the process); then proceed to the next process (i.e., the prying seat process), the drive device drives the pry bar 42 to move towards the second fixed position 510, so that the pry bar 42 is inserted into the inner cavity of the bearing from top to bottom, and the bearing is pried by the pry bar, and under the action of external force, the bearing is completely pried into the bearing seat (i.e., the second state in the process); then proceed to the next process (i.e., the prying seat process), the drive device drives the pry bar 42 to move towards the second fixed position 510, so that the pry bar 42 is inserted into the inner cavity of the bearing from top to bottom, and the bearing is pried into the bearing seat by the pry bar, and under the action of external force ..., the bearing is completely pried into the bearing seat (i.e., the second state in the process). Figure 12 The third state in the process completes the assembly between the bearing and the bearing housing. The assembled workpiece is then transported to the subsequent process (such as film wrapping or box packaging) by the discharge mechanism 2. Previously, the pre-push and prying steps could only be done manually, which was very inconvenient.

[0041] The fully automatic spherical bearing seat assembly machine provided by this invention has the following beneficial effects:

[0042] It realizes fully automated operation of the outer spherical ball bearing and bearing housing from loading, assembly to unloading. The assembly process does not require manual prying of the housing, which greatly reduces the labor intensity of workers. At the same time, the automated operation is more conducive to efficient assembly work, improves the overall work efficiency, and also ensures a certain level of assembly quality, reducing the product defect rate.

[0043] refer to Figure 4 and 5 In a preferred embodiment, the driving device includes a lateral driving member 40 and a longitudinal driving member 41, which are connected by a transmission connection. The longitudinal driving member 41 is also connected to a pry bar 42. The lateral driving member 40 can drive the longitudinal driving component to move back and forth (the back and forth movement referred to here is...). Figure 4 (in the left and right directions); the longitudinal drive member 41 can drive the pry bar 42 to move up and down along the second fixed position 510. The prying process is as follows: first, the longitudinal drive member 41 drives the pry bar 42 to move downward until the pry bar 42 is inserted into the inner cavity of the bearing. Then, the transverse drive member 40 drives the pry bar 42 to move back and forth. The process of the pry bar 42 moving back and forth continuously simulates the action of a human hand prying. It can be regarded as inserting one end of the pry bar 42 into the inner cavity of the bearing, and then a person holds the other end of the pry bar 42 and pries it up and down, thereby prying the bearing into the bearing seat.

[0044] refer to Figure 3-5 In a further preferred embodiment, the direction of movement of the push rod 31 driven by the longitudinal drive member 41 is perpendicular to the direction of movement of the pry bar 42 driven by the first drive source 30. Specifically, in this embodiment, the longitudinal drive member 41 is disposed above the second fixed position 510, and the pre-push mechanism 3 is disposed on one side of the first fixed position 501 (the first fixed position 501 and the second fixed position 510 can refer to the same fixed position). Although both move towards the fixed position, their directions of movement are not the same; "perpendicular" means that their directions of movement are relatively perpendicular. (Reference) Figure 3 The direction of motion of push rod 31 is forward and backward (i.e., Figure 3 (In the left and right direction), the direction of the pry bar 42 when inserted into the bearing is up and down; by pushing the bearing with the push rod 31, its angle is tilted, so that the opening direction of the bearing cavity is upward, so that the pry bar 42 can be smoothly inserted into the bearing cavity when it moves downward.

[0045] refer to Figure 4-5 In a preferred embodiment, the driving device includes a transverse driving member 40 and a longitudinal driving member 41 connected together. The transverse driving member 40 includes a second driving source 401, a fixed base 402, and a slide 403. The fixed base 402 is located on one side of the second assembly table 51. The second driving source 401 can drive the slide 403 to slide back and forth on the fixed base 402. A position sensor (not shown) is also provided on the fixed base. The position sensor is electrically connected to the second driving source and is used to detect the movement stroke of the second driving source. In this embodiment, the second driving source 401 is a motor and a lead screw. The motor is fixed to the fixed base 402. One end of the lead screw is connected to the motor, and the other end is connected to the slide 403. The lead screw can convert the circumferential motion of the motor into axial motion, thereby driving the slide 403 to reciprocate on the fixed base 402. In other embodiments, the second driving source 401 can also be a cylinder. The output end of the cylinder can be connected to the slide 403. The extension and retraction of the cylinder can also drive the slide 403 to reciprocate on the fixed base 402. The longitudinal drive component 41 is mounted on the slide block 403. The process of the second drive source 401 driving the slide block 403 to move back and forth also drives the pry bar 42 to move back and forth (the so-called back and forth movement refers to...). Figure 4 (Moves left and right in the middle), the longitudinal drive member 41 is located above the second assembly table 51. The longitudinal drive member 41 includes a third drive source 410 (such as a cylinder) and a mounting base 411. The mounting base 411 is hinged to the slide 403. The mounting base 411 can swing relative to the slide 403 around the hinge point. The third drive source 410 is provided on the mounting base 411, and the output end of the third drive source 410 is connected to the pry bar 42. The third drive source 410 can drive the pry bar 42 to move up and down in the direction of the second fixed position 510.

[0046] The working principle of the drive device is as follows: First, the third drive source 410 of the longitudinal drive member 41 drives the pry bar 42 downward until one end of the pry bar 42 is inserted into the inner cavity of the bearing. Then, the second drive source 401 of the transverse drive member 40 drives the pry bar 42 to move back and forth, forming a prying action on the bearing. Specifically, when the lower end of the pry bar 42 (the end closest to the workpiece fixing position) extends into the inner cavity of the bearing, it will abut against the inner wall of the bearing (equivalent to the place where the pry bar 42 contacts the inner wall of the bearing forming a support point). At this time, when the second drive source 401 drives the pry bar 42 to move back and forth, the upper end of the pry bar 42 will naturally swing to a certain extent, which simulates the action of manually prying the bearing (that is, manually inserting one end of the pry bar 42 into the inner cavity of the bearing, and then holding the other end of the pry bar 42 and prying it up and down). Therefore, through the hinged design between the mounting base 411 and the slide 403, the other end of the pry bar 42 can have a certain swing space, thereby prying the bearing into the bearing housing. This method transforms actions that originally required manual operation into mechanical control, further improving assembly efficiency while reducing the labor intensity of manual workers.

[0047] In a further preferred embodiment, a pressure sensor (not shown) is also provided on the fixed base, and the pressure sensor is electrically connected to the second drive source. The pressure sensor can be used to detect the prying force (torque) during the prying process. Specifically, by detecting whether the torque in the actual process exceeds a preset range value, the tightness of the assembly between the bearing and the bearing housing can be determined. During the assembly process, if the torque is too large, it may cause the assembly between the bearing and the bearing housing to be too tight; while if the torque is too small, it may cause the assembly to be too loose. Both excessive tightness and excessive looseness will affect the final assembly quality. Therefore, by setting a pressure sensor, the prying force can be better controlled within a suitable range value to improve the assembly quality between the bearing and the bearing housing.

[0048] refer to Figure 4-5 In a preferred embodiment, the slide 403 is provided with a guide plate 412, which is located on one side of the mounting base 411 and extends upward relative to the slide 403. The guide plate 412 has a guide groove 413 along its height direction, and the mounting base 411 is provided with a guide rod 414, which is matched and connected to the guide groove 413. Through the mutual cooperation between the guide groove 413 and the guide rod 414, the pry bar 42 has a certain limiting effect during its swinging process.

[0049] refer to Figure 1 , 2In preferred embodiments, 6 and 8 further include a pre-assembly mechanism 6, located between the feeding mechanism 1 and the pre-pushing mechanism 3. The pre-assembly mechanism 6 includes a third assembly table 52 and a first clamping and transferring part 60. The feeding mechanism 1 includes a bearing loading platform 10 and a bearing housing loading platform 11, located on opposite sides of the third assembly table 52. The first clamping and transferring part 60 can reciprocate between the bearing loading platform 10, the bearing housing loading platform 11, and the third assembly table 52. The pre-assembly mechanism 6 is mainly used to pre-place the bearing into the bearing housing. The first clamping and transferring part 60 first clamps the bearing housing from the bearing housing loading platform 11 to the third assembly table 52, then clamps the bearing and places it in the bearing housing to form a bearing with a housing, before proceeding to the next process. This eliminates the tedious manual pre-assembly, automatically completing the pre-assembly work and further improving assembly efficiency. In this embodiment, the first assembly station 50, the second assembly station 51, and the third assembly station 52 can be integrated into one unit.

[0050] refer to Figure 1 , 2 6. In a preferred embodiment, the first clamping and transferring unit 60 includes a support frame 601, a connecting plate 602 slidably connected to the top of the support frame 601, and a first power component 603 for driving the connecting plate 602 to move. A clamping robot 604 is provided on the connecting plate 602. Both the connecting plate 602 and the clamping robot 604 are located above the bearing loading platform 10, the bearing housing loading platform 11, and the third assembly table 52. Multiple clamping robots 604 are provided, spaced apart along the length of the connecting plate 602. By providing multiple clamping robots 604, the bearing and bearing housing can be clamped simultaneously, resulting in higher efficiency. Furthermore, the connecting plate 602 is equipped with multiple lifting cylinders 605, each of which is connected to the clamping robot 604. During operation, the first power component 603 drives the connecting plate 602 to move left and right above the bearing loading platform 10 / bearing housing loading platform 11. Then, the lifting cylinders 605 control the clamping robot 604 to descend onto the platform to clamp the workpiece. After clamping, the lifting cylinders 605 control the clamping robot 604 to rise. Then, the first power component 603 drives the clamping robot 604 to move horizontally above the third assembly table 52. At this time, the lifting cylinders 605 work again to drive the clamping robot 604 to descend, placing the clamped workpiece onto the assembly table, and then rising again. This cycle repeats to complete the pre-assembly work between the bearing and the bearing housing.

[0051] refer to Figure 2 and 7In a preferred embodiment, the system further includes a stop ball positioning mechanism 70 and a flipping mechanism 71. The feeding mechanism 1 includes a bearing loading platform 10, and the bearing loading platform 10, the stop ball positioning mechanism 70, and the flipping mechanism 71 are arranged sequentially along the material feeding direction. The flipping mechanism 71 includes a fixing member 710 and a flipping drive member 711 connected to one end of the fixing member 710 for driving the fixing member 710 to flip. The flipping drive member 711 drives the fixing member 710 to flip at an angle of 90°±5°. The stop ball positioning mechanism 70 is mainly used to determine the position of the stop ball on the outer ring spherical surface of the bearing, thereby ensuring that the position of the stop ball matches the position of the concave spherical surface in the bearing housing during assembly. For the structure of the stop ball positioning mechanism 70, please refer to the applicant's previous Chinese patent CN209664731U. The structure of the stop ball positioning mechanism 70 in this application is the same as that in the patent document.

[0052] refer to Figure 7 The flipping mechanism 71 is mainly used to flip the angle of the bearing so that it is placed vertically in the inner cavity of the bearing housing (the vertical orientation referred to here is as follows). Figure 10 (Regarding the bearing's orientation), the flipping drive 711 can be a rotary cylinder; after the stop ball positioning mechanism 70 completes the positioning test of the bearing, it proceeds to the next process, placing the positioned bearing on the fixing part 710. The flipping drive 711 drives the fixing part 710 to rotate, simultaneously causing the bearing to flip. The preferred flipping angle is 90°, although there may be a 5° error in actual operation. For example, the actual flipping angle may be 85°, 90°, or 95°, but 90° is preferred. At this point, the bearing changes from an orientation with the cavity opening facing upwards to an orientation with the cavity opening facing both sides (e.g., ...). Figure 6 The bearing shown is in a vertical position. Then, the first clamping and transferring part 60 clamps it and places it into the bearing housing for the next pre-pushing process. Further, the fixing member 710 includes two parallel clamping plates. A clamping cylinder 712 is connected to the end of the flipping drive member 711. In one embodiment, the output end of the clamping cylinder 712 is connected to the two clamping plates, allowing control to move the two clamping plates closer or further apart, thereby clamping or releasing the bearing. In another embodiment, the output end of the clamping cylinder 712 is connected to one of the clamping plates, allowing control to move one clamping plate closer or further away from the other clamping plate, thereby clamping or releasing the bearing.

[0053] refer to Figure 2 and 7In a preferred embodiment, a second clamping and transferring unit 74 is also included. A face recognition mechanism 72 and a flipping mechanism 73 are provided between the bearing loading platform 10 and the stop ball positioning mechanism 70. The bearing loading platform 10 includes a bearing loading belt 101 and a pushing part 102. The pushing part 102 and the face recognition mechanism 72 are located on opposite sides of the bearing loading belt 101, respectively. The pushing part 102 can move towards the face recognition mechanism 72. The second clamping and transferring unit 74 can reciprocate between the face recognition mechanism 72 and the flipping mechanism 71. The face recognition mechanism 72 is mainly used to detect that the side of the bearing outer ring with the stop ball is facing upwards. If it is detected that it is not facing upwards, the flipping mechanism 73 flips the bearing by 180°±5°. In this embodiment, the flipping mechanism 73 and the flipping mechanism 71 have the same structure. The only difference is that the flipping mechanism 73 flips the bearing by 180°, while the flipping mechanism 71 flips the bearing by 90°. In practice, a certain angle error is allowed. Of course, the bearing can also be controlled to be on the correct assembly side when the material is received in the early stages of the process. This way, there is no need to set up an additional face recognition mechanism 72 and a face flipping mechanism 73 to recognize and flip the bearing.

[0054] refer to Figure 7 In a further preferred embodiment, the bearing feeding belt 101 can be driven to rotate by a drive motor. Specifically, the two ends of the bearing feeding belt 101 are connected to transmission rollers. The drive motor drives the bearing feeding belt 101 to rotate through the transmission rollers, thereby conveying the bearing. The pushing part 102 includes a pushing cylinder 1020 and a pushing plate 1021. When the bearing is conveyed to the front of the pushing plate 1021, the pushing cylinder 1020 drives the pushing plate 1021 to move, pushing the bearing toward the work position of the face recognition mechanism 72. The bearing feeding belt 101 and the detection work position of the face recognition mechanism 72 are at the same horizontal height.

[0055] refer to Figure 7 In a further preferred embodiment, the second clamping and transferring part 74 is disposed on one side of the face recognition mechanism 72. The second clamping and transferring part 74 includes an X-axis slide 740, a Y-axis slide 741, and a clamping plate 742 connected in sequence. The clamping plate has a notch on the side facing the face recognition mechanism 72 for clamping the bearing. The Y-axis slide 741 is disposed on the X-axis slide 740. One end of the X-axis slide 740 is connected to an X-axis drive cylinder, and the bottom of the X-axis slide 740 is connected to a slide rail. The X-axis drive cylinder is used for... The X-axis slide 740 is driven to reciprocate between the face recognition mechanism 72 and the flipping mechanism 71; one end of the Y-axis slide 741 is connected to a Y-axis drive cylinder, which is used to drive the Y-axis slide 741 to move back and forth (i.e., reciprocate towards the face recognition mechanism 72). During the back and forth movement of the Y-axis slide 741, the bearing can be engaged in the notch of the clamping plate 742 or disengaged from the notch of the clamping plate 742, thereby realizing the transportation of the bearing between the face recognition mechanism 72 and the flipping mechanism 71.

[0056] refer to Figure 1 , 2 9. In a preferred embodiment, a correction mechanism 8 is further included, which is located between the skid mechanism 4 and the discharge mechanism 2. The correction mechanism 8 is mainly used to apply a certain pressure to the assembled bearing again to make it correctly positioned and to avoid any misalignment after skidding. Specifically, the correction mechanism 8 includes a correction table 80, a correction pressure head 81 and a correction drive cylinder 82 disposed on the correction table 80; similarly, a workpiece fixing position is provided below the correction pressure head 81, and the correction pressure head 81 is spaced above the workpiece fixing position. The correction drive cylinder 82 is used to drive the correction pressure head 81 to move towards the workpiece fixing position, so that the correction pressure head 81 further presses and corrects the assembled bearing to avoid misalignment. The workpiece fixing position in this embodiment is the same as the workpiece fixing position structure of other assembly mechanisms, or it can be shared with other assembly mechanisms.

[0057] In a further preferred embodiment, a third clamping and transferring part is provided between the first assembly table 50 and the correction table 80. The third clamping and transferring part is used to clamp the workpiece to different processing stations. The structure of the third clamping and transferring part can be the same as that of the second clamping and transferring part 74.

[0058] The automatic assembly machine for outer spherical ball bearings in this invention works as follows:

[0059] First, the bearing and bearing housing are loaded onto the bearing loading platform 10 and bearing housing loading platform 11 respectively. Then, the bearing is inspected by the face recognition mechanism 72, and the inspection results determine whether the bearing needs to be flipped 180°. If flipping is required, the bearing is flipped 180° by the flipping mechanism 71. Next, the stop ball positioning process is performed to determine the assembly position between the bearing and the bearing housing (i.e., the stop ball matches the concave spherical surface inside the bearing housing). Then, the bearing is flipped 90° by the flipping mechanism 71, changing it from a horizontal to a vertical position. During these processes, the bearing can be clamped and transferred by the second clamping and transferring unit 74. Afterwards, the first clamping and transferring unit 60 clamps the bearing and bearing housing respectively, and places them on the workpiece fixing position of the pre-assembly mechanism 6 to complete the initial pre-assembly. Then, the pre-pushing mechanism 3 pushes the part of the bearing protruding from the bearing housing by the push rod 31, causing the bearing to tilt at a certain angle within the bearing housing (changing from a vertical to an inclined state, i.e., from a horizontal to an inclined state). Figure 10 The first state in the middle is transformed into Figure 11In the second state of the process, the longitudinal drive member 41 of the prying mechanism 4 drives the pry bar 42 to be inserted into the inner cavity of the bearing, and the transverse drive member 40 drives the pry bar 42 to move back and forth to form a prying action, so that the bearing is completely pryed into the bearing seat, completing the entire assembly work; finally, the assembled bearing with seat is pressed and corrected by the correction mechanism 8, and then the product is transferred to the next process by the unloading mechanism 2 for plastic film or packaging.

[0060] This assembly machine automates the entire process of assembling bearings and bearing housings, resulting in higher assembly efficiency and a certain level of quality assurance.
