Description

Technical Field

[0002] Spherical ball bearings, also known as outer spherical bearings, belong to deep groove ball bearings. They are characterized by a spherical outer diameter surface of the outer ring, which can be matched with the corresponding concave spherical surface of the bearing seat (ball seat) to play a role in self-alignment. Each set of spherical ball bearings is not used alone. They must be installed inside the bearing seat as a whole.

[0039] refer to Figure 1-12The 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 incoming direction; a pre-pushing mechanism 3 and a prying mechanism 4 are arranged 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 along the incoming direction, according to the order of the assembly process, that is, 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); and also includes a controller (such as a PLC controller), the feeding mechanism 1, the discharging mechanism 2, the pre-pushing mechanism 3 and the prying mechanism 4 are arranged between the feeding mechanism 1 and the discharging mechanism 2. The mechanism 3 and the sled mechanism are both electrically connected to the controller. The pre-pushing mechanism 3 and the sled mechanism 4 both include a workpiece fixing device 53, which is used to fix the workpiece (i.e., the seat 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 the first fixed position 501 / the second fixed position 510. The pressing plate is driven by the power to move to the top of 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 sled mechanism 4 includes a driving device, a pry bar 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 pry bar 42 to move toward the second fixed position 510. like 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 present invention 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. Fig.10 The first state in the assembly process is then placed on the first fixed position 501, and the two ends of the bearing seat are fixed by the workpiece fixing device 53 to prevent the bearing seat from displacement during the assembly process; at this time, the first driving source 30 (such as a cylinder) drives the push rod 31 to move in the direction of the first fixed position 501, so that the push rod 31 contacts the bearing and forms 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. Fig.11Then, the next step (i.e., the prying seat step) is entered, and the pry bar 42 is driven by the driving device 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., Fig.12 The third state in the drawing) is achieved, thereby completing 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 present invention 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 the overall work efficiency, and the assembly quality is also guaranteed to a certain extent, 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 a 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 driving 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 driving member 41 first drives the pry bar 42 to move downward until the pry bar 42 is inserted into the inner cavity of the bearing, and then the transverse driving member 40 drives the pry bar 42 to move forward and backward. The process of the pry bar 42 moving forward and backward simulates the action of prying by human hands, which can be regarded as inserting one end of the pry bar 42 into the inner cavity of the bearing, and then the human hand 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 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 may refer to the same fixed position). Although both move in the direction of the fixed position, the movement directions of the two are not the same. 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; the bearing is pushed by the push rod 31 to make its angle relatively inclined, so that the opening direction of the bearing inner cavity is upward, thereby facilitating the pry bar 42 to be smoothly inserted into the bearing inner cavity when it moves downward.

[0045] refer to Figure 4-5 In a preferred embodiment, the driving device includes a connected transverse driving member 40 and a longitudinal driving member 41; the transverse driving member 40 includes a second driving 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, and the second driving source 401 can drive the slide 403 to slide forward and backward on the fixed seat 402; a position sensor (not shown) is also provided on the fixed seat, and the position sensor is electrically connected to the second driving source for detecting the motion stroke of the second driving source. In this embodiment, the second driving source 401 is a motor and a screw rod, the motor is fixed to the fixed seat 402, one end of the screw rod is connected to the motor, and the other end is connected to the slide 403, the screw rod can convert the circumferential motion of the motor into axial motion, thereby driving the slide 403 to reciprocate on the fixed seat 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, and the reciprocating motion of the slide 403 on the fixed seat 402 can also be driven by the telescopic motion of the cylinder. The longitudinal driving member 41 is disposed 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 arranged 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 in the direction of the second fixed position 510.

[0046] The working principle of the driving device is as follows: first, the third driving source 410 of the longitudinal driving 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 driving source 401 of the transverse driving member 40 drives the pry bar 42 to move forward and backward, thereby forming a prying action on the bearing. Specifically, when the lower end of the pry bar 42 (the end close 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 to form a support point), at this time, when the second driving source 401 drives the pry bar 42 to move forward and backward, the upper end of the pry bar 42 will naturally have a certain swing, 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, through the hinged design between the mounting seat 411 and the sliding seat 403, the other end of the pry bar 42 can have a certain swing space, thereby prying the bearing into the bearing seat. In this way, the actions that originally needed to be operated manually are transformed into mechanical control, which further improves the efficiency of assembly and reduces the labor intensity of manual labor.

[0047] In a further preferred embodiment, a pressure sensor (not shown) is further provided on the fixed seat, and the pressure sensor is electrically connected to the second driving 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 the preset range value, the tightness of the assembly between the bearing and the bearing seat can be 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, so by setting the 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 the guide plate 412 is extended upward relative to the slide 403; a guide groove 413 is provided along the height direction of the guide plate 412, and a guide rod 414 is provided on the mounting seat 411, and the guide rod 414 is matched and connected with 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 the swinging process.

[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 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 reciprocate 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 with a seat, and then enters the next process, eliminating the tediousness of manual pre-installation, automatically completing the pre-installation work, and 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 may be integrally arranged.

[0050] refer to Figure 1 , 2 6. In a preferred embodiment, the first clamping and transferring part 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 driving the connecting plate 602 to move; a clamping manipulator 604 is arranged on the connecting plate 602, and the connecting plate 602 and the clamping manipulator 604 are both located above the bearing loading platform 10, the bearing seat loading platform 11 and the third assembly platform 52. There are multiple clamping manipulators 604, and the multiple clamping manipulators 604 are arranged at intervals along the length direction of the connecting plate 602. By arranging multiple clamping manipulators 604, the bearing and the bearing seat can be clamped at the same time, which is more efficient. 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 to clamp the workpiece by the lifting cylinder 605. 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 by 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 the preferred embodiment, it also includes a stop ball positioning mechanism 70 and a flip mechanism 71. The feeding mechanism 1 includes a bearing feeding platform 10. The bearing feeding platform 10, the stop ball positioning mechanism 70 and the flip mechanism 71 are arranged in sequence along the incoming material direction; the flip mechanism 71 includes a fixing member 710, and a flip driving member 711 connected to one end of the fixing member 710 for driving the fixing member 710 to flip; the flip driving 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 spherical surface of the outer ring of the bearing, so as to ensure that the position of the stop ball matches the position of the concave spherical surface in the bearing seat during assembly. The structure of the stop ball positioning mechanism 70 can be referred to the Chinese patent CN209664731U previously applied by the applicant. The structure of the stop ball positioning mechanism 70 in this application is the same as the structure in the 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 Fig.10 The flipping 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 flipping drive 711 drives the fixing member 710 to rotate and also drives the bearing to flip. The flipping 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 flipping angle may be 85°, 90° or 95°, preferably 90°. At this time, the bearing changes from a posture with the cavity facing upward to a posture with the cavity facing both sides (such as Figure 6 The bearing shown in the figure is in a vertical state), and then the first clamping and transferring part 60 clamps it into the bearing seat to carry out the next pre-pushing process. Further, the fixing member 710 includes two clamping plates arranged in parallel, and 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, and the two clamping plates can be controlled to move closer to 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, and one of the clamping plates can be controlled to move closer to or farther from the other clamping plate, thereby clamping or loosening the bearing.

[0053] refer to Figure 2 and 7In the preferred embodiment, the second clamping and transferring part 74 is also included. A 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 push part 102. The push part 102 and the recognition mechanism 72 are respectively located on both sides of the bearing loading belt 101. The push part 102 can move in the direction of the recognition mechanism 72. The second clamping and transferring part 74 can reciprocate between the recognition mechanism 72 and the flipping mechanism 71. The recognition mechanism 72 is mainly used to detect that the side with the stop ball on the outer ring of the bearing is facing upward. If it is detected that it is not facing upward, the flipping mechanism 73 flips the bearing by 180°±5°. In this embodiment, the flipping mechanism 73 has the same structure as the flipping mechanism 71. The only difference is that the flipping mechanism 73 flips the bearing at an angle of 180°, and the flipping mechanism 71 flips the bearing at an angle of 90°. In practice, a certain angle 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 with the correct assembly, so that there is no need to additionally set up the face recognition mechanism 72 and the face turning mechanism 73 to recognize and turn 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.

[0058] The automatic assembly machine for external spherical ball bearings of the present invention works as follows:

[0059] First, the bearing and the bearing seat are loaded respectively through the bearing loading platform 10 and the bearing seat loading platform 11, and then the incoming bearing is inspected by the recognition mechanism 72, and it is determined whether the bearing needs to be turned over 180° based on the inspection results. If it needs to be turned over, the bearing is 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-mentioned processes, the bearing can be clamped and transferred by the second clamping and transferring part 74. After that, the first clamping and transferring part 60 clamps the bearing 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 part of the bearing protruding from the bearing seat is pushed by the push rod 31, so that the bearing has a certain angle of inclination in the bearing seat (from a vertical state to an inclined state, that is, by Fig.10 The first state in the transformation is Fig.11The second state in the assembly process is completed; 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, and the entire assembly work is completed; finally, the assembled bearing seat 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.
