[0002] Insert ball bearings, also commonly known as outer spherical bearings, belong to the category of deep groove ball bearings. Their characteristic is that the outer diameter surface of their outer ring is spherical, which can be fitted into the corresponding concave spherical surface of the bearing seat (ball seat) to play a role in centering. Each set of insert ball bearings is not used alone, but must be installed inside the bearing seat as a whole.

The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0039] refer to Figure 1-12 The present invention provides a fully automatic outer spherical ball bearing seat assembly machine, comprising a feeding mechanism 1 and a discharging mechanism 2 arranged in sequence along the direction of incoming materials; a pre-pushing mechanism 3 and a prying mechanism 4 are provided between the feeding mechanism 1 and the discharging mechanism 2 (the so-called between the feeding mechanism 1 and the discharging mechanism 2 here refers to the direction of incoming materials. According to the order of the assembly process, the pre-pushing mechanism 3 is located downstream of the feeding mechanism 1, and the prying mechanism 4 is located downstream of the pre-pushing mechanism 3 and upstream of the discharging mechanism 2); the pre-pushing mechanism 3 and the prying mechanism 4 both include a workpiece fixing device 53, which is used to fix the workpiece (i.e., the seated bearing) during assembly. The workpiece fixing device 53 can be the same or multiple; the workpiece fixing device 53 includes a pressing plate and a power (such as a cylinder or a hydraulic cylinder) that drives the pressing plate to move toward a first fixed position 501 / a second fixed position 510; the power drives the pressing plate to move above the first fixed position 501 / the second fixed position 510, thereby fixing the workpiece in the fixed position to prevent it from shaking. The pre-pushing mechanism 3 includes a first driving source 30, a push rod 31 and a first assembly platform 50. The first assembly platform 50 is provided with a first fixed position 501. The first driving source 30 can drive the push rod 31 to move toward the first fixed position 501. The prying mechanism 4 includes a driving device, a prying rod 42 and a second assembly platform 51. The second assembly platform 51 is provided with a second fixed position 510. The driving device can drive the prying rod 42 to move toward the second fixed position 510. Figure 8 As shown, the first assembly station 50 and the second assembly station 51 may be a plurality of integral arrangements.

[0040] The fully automatic outer spherical ball bearing seat assembly machine provided by the utility model has the following working principle: during assembly, the outer spherical ball bearing (hereinafter referred to as: bearing) and the bearing seat (mainly a square bearing seat / diamond bearing seat) are loaded through the feeding mechanism 1, and the bearing can be preliminarily placed in the bearing seat in a certain posture to form a seated bearing. At this time, the two ends of the bearing protrude from the bearing seat setting (i.e. Figure 10The first state in the assembly process is then performed), and the first fixed position 501 is placed on the first fixed position, and the two ends of the bearing seat are fixed by the workpiece fixing device 53 to prevent the bearing seat from being displaced during the assembly process; at this time, the first driving source 30 (such as a cylinder) drives the push rod 31 to move toward the first fixed position 501, so that the push rod 31 contacts the bearing and generates a thrust on the bearing, and the push rod 31 pushes the part of the bearing protruding from the bearing seat, so that the bearing has a certain angle of inclination in the bearing seat (i.e. Figure 11 Then, the next step (i.e., the pry seat step) is entered, and the driving device drives the pry bar 42 to move toward 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 the bearing is completely pried into the bearing seat under the action of external force (i.e., Figure 12 The third state in the drawing) completes the assembly between the bearing and the bearing seat. The assembled workpiece is transported to the subsequent process (such as film covering or packaging) through the discharge mechanism 2. In the past, the two steps of pre-pushing and prying the seat could only be performed manually, which was very inconvenient.

[0041] The fully automatic outer spherical ball bearing seat assembly machine provided by the utility model has the following beneficial effects:

[0042] The fully automated operation between the outer spherical ball bearing and the bearing seat from loading, assembly to unloading is realized. No manual prying is required during the assembly process, which greatly reduces the labor intensity of workers. At the same time, the use of automated operation is more conducive to efficient assembly work, improves overall work efficiency, and also has a certain guarantee for assembly quality, reducing the defective rate of products.

[0043] refer to Figure 4 and 5 In a preferred embodiment, the driving device includes a transverse driving member 40 and a longitudinal driving member 41. The transverse driving member 40 is connected to the longitudinal driving member 41 through a transmission connection, and the longitudinal driving member 41 is also connected to the pry bar 42; the transverse driving member 40 can drive the longitudinal driving assembly to move forward and backward (the forward and backward movement referred to here is Figure 4 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: the longitudinal drive member 41 first drives the pry bar 42 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 back and forth. This continuous back and forth movement of the pry bar 42 simulates the action of a human hand prying. It can be thought of as 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 up and down, thereby prying the bearing into the bearing seat.

[0044] refer to Figure 3-5In a further preferred embodiment, the movement direction of the push rod 31 driven by the longitudinal driving member 41 is perpendicular to the movement direction of the pry bar 42 driven by the first driving source 30. Specifically, in this embodiment, the longitudinal driving member 41 is arranged above the second fixed position 510, and the pre-pushing mechanism 3 is arranged on one side of the first fixed position 501 (the first fixed position 501 and the second fixed position 510 here can refer to the same fixed position). Although both move toward the fixed position, their movement directions are different. The so-called vertical means that the movement directions of the two are relatively perpendicular. Figure 3 , the movement direction of the push rod 31 is forward and backward movement (i.e. Figure 3 The direction in which the pry bar 42 is inserted into the bearing is up and down movement; the bearing is pushed by the push rod 31 so that its angle is relatively tilted, so that the opening direction of the bearing cavity is upward, thereby facilitating the pry bar 42 to be smoothly inserted into the bearing cavity when moving downward.

[0045] refer to Figure 4-5 In a preferred embodiment, the drive device includes a connected transverse drive member 40 and a longitudinal drive member 41; the transverse drive member 40 includes a second drive source 401, a fixed seat 402 and a slide 403, the fixed seat 402 is located on one side of the second assembly platform 51, the second drive source 401 can drive the slide 403 to slide back and forth on the fixed seat 402, and a position sensor (not shown) is also provided on the fixed seat, the position sensor is electrically connected to the second drive source for detecting the motion stroke of the second drive source. In this embodiment, the second drive source 401 is a motor and a screw, the motor is fixed to the fixed seat 402, one end of the screw is connected to the motor, and the other end is connected to the slide 403, the screw can convert the circumferential motion of the motor into axial motion, thereby driving the slide 403 to move back and forth on the fixed seat 402, in other embodiments, the second drive source 401 can also be a cylinder, the output end of the cylinder can be connected to the slide 403, and the telescopic motion of the cylinder can also drive the slide 403 to move back and forth on the fixed seat 402. The longitudinal driving member 41 is arranged on the slide 403. The second driving source 401 drives the slide 403 to move forward and backward, and also drives the pry bar 42 to move forward and backward (the so-called forward and backward movement refers to the Figure 4 The longitudinal drive member 41 is located above the second assembly table 51, and the longitudinal drive member 41 includes a third drive source 410 (such as a cylinder) and a mounting seat 411. The mounting seat 411 is hinged to the slide 403, and the mounting seat 411 can swing relative to the slide 403 around the hinge; the third drive source 410 is provided on the mounting seat 411, and the output end of the third drive source 410 is connected to the pry bar 42, and the third drive source 410 can drive the pry bar 42 to move up and down along the direction of the second fixed position 510.

[0046] The operating 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 to move downward until one end of the pry bar 42 is inserted into the inner cavity of the bearing, and 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 near the workpiece fixing position) extends into the inner cavity of the bearing, it will contact the inner wall of the bearing (equivalent to the contact point between the pry bar 42 and the inner wall of the bearing to form 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, that is, simulating the action of manually prying the bearing (i.e., 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 up and down). Therefore, the hinged design between the mounting seat 411 and the slide seat 403 allows the other end of the pry bar 42 to have a certain amount of swing space, thereby prying the bearing into the bearing seat. In this way, the actions that originally required manual operation are transformed into mechanical control, further improving the efficiency of assembly while reducing the labor intensity of manual labor.

[0047] In a further preferred embodiment, a pressure sensor (not shown) is further provided on the fixing seat, and the pressure sensor is electrically connected to the second driving source; the pressure sensor is mainly used to detect the prying force (torque) during the prying process, specifically: by detecting whether the torque in the actual process exceeds the set range value, the tightness of the assembly between the bearing and the bearing seat is judged; during the assembly process, if the torque is too large, the assembly between the bearing and the bearing seat may be too tight; and if the torque is too small, the assembly of the two may be too loose. Whether it is too tight or too loose, it will affect the final assembly quality. Therefore, by providing a pressure sensor, the prying force can be better controlled within an appropriate range value to improve the assembly quality between the bearing and the bearing seat.

[0048] refer to Figure 4-5 In a preferred embodiment, a guide plate 412 is provided on the slide 403. The guide plate 412 is located on one side of the mounting seat 411 and extends upward relative to the slide 403. A guide groove 413 is defined along the height of the guide plate 412. The mounting seat 411 is provided with a guide rod 414, which is mated with the guide groove 413. The interaction between the guide groove 413 and the guide rod 414 provides a certain degree of positional restraint during the swinging of the pry bar 42.

[0049] refer to Figure 1 、 2, 6, 8, in the preferred embodiment, it also includes a pre-installation mechanism 6, which is located between the feeding mechanism 1 and the pre-pushing mechanism 3; the pre-installation mechanism 6 includes a third assembly platform 52 and a first clamping and transferring part 60; the third assembly platform 52 is also provided with a third fixed position 520, the feeding mechanism 1 includes a bearing loading platform 10 and a bearing seat loading platform 11, the bearing loading platform 10 and the bearing seat loading platform 11 are respectively located on both sides of the third assembly platform 52, and the first clamping and transferring part 60 can move back and forth between the bearing loading platform 10, the bearing seat loading platform 11 and the third assembly platform 52. The pre-installation mechanism 6 is mainly used to pre-place the bearing into the bearing seat, and the first clamping and transferring part 60 first clamps the bearing seat from the bearing seat loading platform 11 to the third assembly platform 52, and then clamps the bearing and places it in the bearing seat to form a bearing seat, and then enters the next process, eliminating the tedious manual pre-installation and automatically completing the pre-installation work, further improving the efficiency of assembly. In this embodiment, the first assembly platform 50, the second assembly platform 51 and the third assembly platform 52 are integrated.

[0050] refer to Figure 1 、 2 6. In a preferred embodiment, the first gripping and transferring portion 60 includes a support frame 601, a connecting plate 602 slidably connected to the top of the support frame 601, and a first power member 603 that drives the connecting plate 602. A gripping manipulator 604 is provided on the connecting plate 602. Both the connecting plate 602 and the gripping manipulator 604 are located above the bearing loading platform 10, the bearing seat loading platform 11, and the third assembly platform 52. There are multiple gripping manipulators 604, which are spaced apart along the length of the connecting plate 602. By providing multiple gripping manipulators 604, the bearing and the bearing seat can be gripped simultaneously, which improves efficiency. Furthermore, a plurality of lifting cylinders 605 are provided on the connecting plate 602, and each lifting cylinder 605 is respectively connected to the clamping robot 604; when working, the connecting plate 602 can be driven to move left and right to above the bearing loading platform 10 / bearing seat loading platform 11 by the first power member 603, and then the clamping robot 604 is controlled to descend to the platform by the lifting cylinder 605 to clamp the workpiece. After the clamping is completed, the lifting cylinder 605 controls the clamping robot 604 to rise again, and then drives the clamping robot 604 to move horizontally to above the third assembly platform 52 through the first power member 603. At this time, the lifting cylinder 605 works again to drive the clamping robot 604 to descend, places the clamped workpiece on the assembly platform, and then rises, and repeats this cycle to complete the pre-installation work between the bearing and the bearing seat.

[0051] refer to Figure 2 and 7In a preferred embodiment, the bearing feed mechanism 1 further includes a stop ball positioning mechanism 70 and a flipping mechanism 71. The feed mechanism 1 includes a bearing loading platform 10, with the bearing loading platform 10, the stop ball positioning mechanism 70, and the flipping mechanism 71 positioned sequentially along the material feed direction. The flipping mechanism 71 includes a fixing member 710 and a flipping driver 711 connected to one end of the fixing member 710 for driving the fixing member 710 to flip. The flipping driver 711 drives the fixing member 710 to flip at an angle of 90°±5°. The stop ball positioning mechanism 70 is primarily used to determine the position of the stop ball on the spherical surface of the bearing outer ring, thereby ensuring that the stop ball matches the concave spherical surface of the bearing seat during assembly. The structure of the stop ball positioning mechanism 70 may be referenced to the Chinese patent CN209664731U previously filed by the present applicant. The structure of the stop ball positioning mechanism 70 in this application is identical to that described in that patent document.

[0052] refer to Figure 7 The flip mechanism 71 is mainly used to flip the angle of the bearing so that it can be placed in the inner cavity of the bearing seat in a vertical posture (the vertical posture referred to here is as follows Figure 10 The flip drive 711 can be a rotary cylinder; when the stop ball positioning mechanism 70 completes the positioning detection of the bearing, it enters the next process, and the positioned bearing is placed on the fixing member 710. The flip drive 711 drives the fixing member 710 to rotate and also drives the bearing to flip. The flip angle of the bearing is preferably 90°. Of course, there is an angular error of 5° up and down in the actual process. For example, the actual flip angle may be 85°, 90° or 95°, preferably 90°. At this time, the bearing changes from a cavity-upward posture to a cavity-side posture (such as Figure 6 The bearing is shown in a vertical position), and then the first clamping and transferring portion 60 clamps it into the bearing seat for the next pre-pushing process. Furthermore, the fixing member 710 includes two parallel clamping plates. A clamping cylinder 712 is connected to the end of the flip driving member 711. In one embodiment, the output end of the clamping cylinder 712 is connected to the two clamping plates, which can be controlled to move the two clamping plates closer or farther from each other, thereby clamping or loosening the bearing. In another embodiment, the output end of the clamping cylinder 712 is connected to one of the clamping plates, which can be controlled to move one clamping plate closer or farther from the other clamping plate, thereby clamping or loosening the bearing.

[0053] refer to Figure 2 and 7In a preferred embodiment, a second clamping and transporting portion 74 is further included. A face recognition mechanism 72 and a flipping mechanism 73 are also 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 pusher 102. The pusher 102 and face recognition mechanism 72 are located on either side of the bearing loading belt 101, respectively. The pusher 102 can move toward the face recognition mechanism 72. The second clamping and transporting portion 74 can reciprocate between the face recognition mechanism 72 and the flipping mechanism 71. The face recognition mechanism 72 is primarily used to detect whether the side of the bearing outer ring with the stop ball is facing upward. If it is not, the flipping mechanism 73 flips the bearing 180°±5°. In this embodiment, the flipping mechanism 73 and the flipping mechanism 71 have the same structure, the only difference being that the flipping mechanism 73 flips the bearing by 180°, while the flipping mechanism 71 flips the bearing by 90°. In practice, a certain angular error is allowed. Of course, it is also possible to control the incoming materials in the early process so that the bearing is kept on the side that is correctly assembled, so that there is no need to additionally set up the face recognition mechanism 72 and the flipping mechanism 73 to recognize and flip the bearing.

[0054] refer to Figure 7 In a further preferred embodiment, the bearing loading belt 101 can be driven to rotate by a driving motor. Specifically, transmission rollers are connected to both ends of the bearing loading belt 101, and the driving motor drives the bearing loading belt 101 to rotate through the transmission rollers, thereby conveying the bearings; 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 to the work station of the recognition mechanism 72. The bearing loading belt 101 and the detection station of the 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 arranged on one side of the recognition mechanism 72, and 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.

[0056] refer to Figure 1 、 2 9. In a preferred embodiment, it also includes a correction mechanism 8, which is arranged between the pry seat mechanism 4 and the discharge mechanism 2. The correction mechanism 8 is mainly used to apply a certain amount of pressure to the assembled bearing again to make it in the right position, so as to avoid the situation where it is not properly assembled after the pry seat. Specifically, the correction mechanism 8 includes a correction table 80, and a correction pressure head 81 and a correction drive cylinder 82 arranged 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 arranged above the workpiece fixing position at intervals. The correction drive cylinder 82 is used to drive the correction pressure head 81 to move in the direction of the workpiece fixing position, so that the correction pressure head 81 can further press and correct the assembled bearing seat to avoid it being not properly assembled. The workpiece fixing position in this embodiment has the same structure as the workpiece fixing position of other assembly mechanisms, and can also share the same workpiece fixing position with other assembly mechanisms.

[0057] In a further preferred embodiment, a third clamping and transferring portion is further included. The third clamping and transferring portion is used to clamp the workpiece to different processing stations. The structure of the third clamping and transferring portion may be the same as that of the second clamping and transferring portion 74 .

[0058] The fully automatic outer spherical ball bearing seat assembly machine in the utility model works as follows:

[0059] First, the bearings and bearing seats are loaded respectively through the bearing loading platform 10 and the bearing seat loading platform 11, and then the incoming bearings are inspected by the recognition mechanism 72, and it is determined whether the bearings need to be turned over 180° based on the inspection results. If it needs to be turned over, the bearings are driven to turn over 180° by the flipping mechanism 71; then the process of positioning the stop ball is entered to determine the assembly position between the bearing and the bearing seat (that is, the stop ball matches the concave spherical surface position in the bearing seat), and then the bearing is flipped 90° by the flipping mechanism 71, so that it is flipped from a horizontal state to a vertical state. In the above processes, the bearings can be clamped and transferred by the second clamping and transferring part 74. Afterwards, the first clamping and transferring part 60 clamps the bearings and the bearing seat respectively, and then places them on the workpiece fixing position of the pre-installation mechanism 6 to complete the preliminary pre-installation work, and then enters the process of the pre-pushing mechanism 3, and the push rod 31 pushes the part of the bearing protruding from the bearing seat, so that the bearing has a certain angle of inclination in the bearing seat (from a vertical state to an inclined state, that is, from a vertical state to an inclined state). Figure 10 The first state in the transformation is Figure 11The second state in the assembly process is completed. Then, the longitudinal driving member 41 of the pry seat mechanism 4 drives the pry bar 42 to be inserted into the inner cavity of the bearing, and the transverse driving member 40 drives the pry bar 42 to move back and forth to form a prying action, so that the bearing is completely pried into the bearing seat, completing the entire assembly work. Finally, the assembled seated bearing is pressed and corrected by the correction mechanism 8, and then the product is transferred to the next process by the discharge mechanism 2 for plastic film or packaging.

[0060] The assembly machine can automate the entire assembly process between the bearing and the bearing seat, which improves the assembly efficiency and ensures the assembly quality to a certain extent.
