[0042] In order to make the purpose, technical scheme and advantages of the utility model more clear and explicit, the utility model is further described in detail below with the help of drawings and examples.

[0043] The utility model embodiment provides a riveting integrated machine for riveting bearing into the shell. Figure 3 The shell 91 is the shell 91 of the iron core micromotor, which is a cylindrical shape with one end opening and one end closed, and the shell 91 forms an inner cavity. The riveting hole 910 is provided at the bottom of the cylinder, which penetrates the outer surface and the inner surface of the bottom of the cylinder. The inner surface faces the inner cavity. The bearing 92 can be cylindrical or stepped, both of which can be applied to the riveting integrated machine. In the following examples, the bearing 92 riveted to the shell 91 is described as an example of a stepped shape. The bearing 92 includes concentric small and large rings, which are arranged along the axial direction and form a central hole 920 together. The central axis of the central hole 920 coincides with the central axes of the small and large rings, and the size of the small ring matches the size of the riveting hole 910 at the bottom of the cylinder of the shell 91.

[0044] Please refer to Figure 1 The riveting integrated machine includes a feeding mechanism 10, a guiding mechanism 20, a traveling mechanism 30 and a riveting mechanism 40.

[0045] The feeding mechanism 10 is used to guide a plurality of bearings 92 out one by one, the guiding mechanism 20 is used to arrange a plurality of bearings 92 along a predetermined path one by one, the traveling mechanism 30 is used to take out a single bearing 92 from the guiding mechanism 20 and stack the bearing 92 with the shell 91, and the riveting mechanism 40 is used to complete the riveting of the bearing 92 and the shell 91.

[0046] The feeding mechanism 10 has a feeding cavity 120 for containing a plurality of bearings 92 and a discharging opening communicating with the feeding cavity 120 and for discharging the bearings 92 one by one.

[0047] Please refer to Figure 2 The feeding mechanism 20 is provided with a guide channel 201 extending along a first direction, which can be the up-down direction, i.e. the guide channel 201 extends along a straight line perpendicular to the horizontal plane. The two ends of the guide channel 201 in the up-down direction form a feeding opening 2011 and a discharging opening 2012, respectively. That is, the upper end of the guide channel 201 forms the feeding opening 2011, and the lower end forms the discharging opening 2012. The guide channel 201 can be used to arrange the bearings 92 discharged from the discharging opening 101 one by one along the up-down direction. In other words, the feeding opening 2011 of the guide channel 201 is opposite to the discharging opening of the feeding mechanism 10. The bearings 92 discharged from the discharging opening enter the guide channel 201 one by one through the feeding opening 2011 and are arranged in the guide channel 201 along the extension direction of the guide channel 201.

[0048] It should be noted that the width of the discharging opening 2012 of the guide channel 201 can be slightly smaller than the diameter of the bearing 92, so that the lowermost bearing 92 in the guide channel 201 is clamped at the discharging opening 2012, thereby preventing the bearings 92 in the guide channel 201 from leaking out of the discharging opening 2012. Alternatively, at least the lowermost bearing 92 in the guide channel 201 is clamped or interference fitted. As long as the lowermost bearing 92 can be limited and other bearings 92 can enter the guide channel 201.

[0049] Please refer to Figure 3 and Figure 4The advancing mechanism 30 includes a riveting piece 31 and a positioning shaft 32. The shell 91 is sleeved on the riveting piece 31, the riveting piece 31 extends into the inner cavity of the shell 91, the top end of the riveting piece 31 is opposite to the inner surface of the bottom of the shell 91, and the positioning shaft 32 is arranged in the riveting piece 31 in the up-down direction, that is, the riveting piece 31 is provided with a through hole 310 in the up-down direction, the positioning shaft 32 is arranged in the through hole 310 and passes through the riveting hole 910 of the shell 91. The advancing mechanism 30 can move in the second direction to drive the positioning shaft 32 to push the bearing 92 at the discharge opening 2012, so that the bearing 92 at the discharge opening 2012 is separated from the guide channel 201 and is sleeved on the positioning shaft 32. Under the action of gravity, the bearing 92 falls on the outer surface of the bottom of the shell 91 along the positioning shaft 32, at this time, the small ring of the bearing 92 is below the large ring, and the small ring can be located outside the riveting hole 910 of the shell 91 or partially enter the riveting hole 910. The second direction is arranged at an angle with the first direction, and in this embodiment, the second direction can be the left-right direction, that is, the second direction is perpendicular to the first direction. The advancing mechanism 30 can further include an advancing drive 33, the movement of the riveting piece 31 and the positioning shaft 32 can be realized by the advancing drive 33, and the advancing drive 33 can provide power for the movement of the riveting piece 31. The advancing drive 33 includes but is not limited to a cylinder, an electric push rod, a linear motor, a hydraulic cylinder and the like.

[0050] It should be noted that the guide-in mechanism 20 avoids the positioning shaft 32 in the movement path of the positioning shaft 32 to avoid affecting the movement of the positioning shaft 32. The positioning shaft 32 can push the lower half of the bearing 92 through the top to make the bearing 92 flip, so that the bearing 92 leaks from the discharge opening 2012 and is sleeved on the positioning shaft 32 through the through hole 920. In order to realize the sleeving of the bearing 92 and the positioning shaft 32, the top of the positioning shaft 32 can be conical. After the bearing 92 at the discharge opening 2012 is moved out of the guide channel 201, the bearing 92 immediately above the bearing 92 at the discharge opening 2012 moves downward under the action of gravity and moves to the discharge opening 2012 to be ready for the next time the positioning shaft 32 pushes.

[0051] The riveting mechanism 40 includes a riveting drive 41 and a pressure head 42 connected to the riveting drive 41. The riveting drive 41 can drive the pressure head 42 to extrude the bearing 92 towards the riveting piece 31, so that the bearing 92 is riveted to the riveting hole 910 of the shell 91. It can be understood that the riveting drive 41 drives the pressure head 42 to extrude the bearing 92 from top to bottom, wherein the pressure head 42 avoids the positioning shaft 32 during downward movement, and the pressure head 42 extrudes the small ring of the bearing 92 into the riveting hole 910 by pressing, and the small ring is riveted to the inner surface of the riveting hole 910 of the bottom of the shell 91 under the support of the top surface of the riveting piece 31. The riveting drive 41 includes but is not limited to a cylinder, an electric push rod, a linear motor, a hydraulic cylinder and the like.

[0052] Please refer to Figure 5 The riveting all-in-one machine is provided with a feeding mechanism 20, so that a plurality of bearings 92 can be arranged in sequence. Then, the positioning shaft 32 pushes the bearing 92 out of the discharging opening 2012, so that the single bearing 92 is moved out of the feeding mechanism 20 and is placed on the riveting hole 910 of the machine shell 91. The positioning shaft 32 also realizes the alignment of the bearing 92 and the riveting hole 910 on the machine shell 91, so that the pressing head 42 can directly rivet the bearing 92 on the riveting hole 910 of the machine shell 91 by pressing. In this way, the machine shell 91 and the bearing 92 realize automatic riveting by the riveting all-in-one machine, without the need for manual participation, saving labor and processing cost, and improving production efficiency.

[0053] Please refer to Figure 3 and Figure 4 Optionally, in order to avoid affecting the middle hole 920 of the bearing 92, the top surface of the riveting piece 31 can be provided with a avoiding groove 3101. The riveting piece 31 rivets the edge portion of the small ring of the bearing 92 through the edge groove side edge portion 132 of the avoiding groove 3101. The avoiding groove 3101 is used to accommodate the main body portion of the small ring, so as to avoid the extrusion deformation of the middle hole 920 of the bearing 92.

[0054] Please refer to Figure 1 In some embodiments, the riveting all-in-one machine further comprises a support frame 80. The feeding mechanism 10, the feeding mechanism 20, the advancing mechanism 30 and the riveting mechanism 40 are connected to the support frame 80 to form an integrated structure.

[0055] Please refer to Figure 6 and Figure 7In some embodiments, the feeding mechanism 10 comprises a stirring driving member 11, a feeding cylinder 12, a feeding base 13, and a stirring member 14. The feeding base 13 comprises a guide portion 131 and a rim portion 132. The guide portion 131 is in the shape of a circular truncated cone or a circular cone. The guide portion 131 has a conical surface 130 arranged around a central axis. The central axis of the guide portion 131 extends in the up-down direction. The bottom of the guide portion 131 has a larger diameter than the top. The rim portion 132 is connected to the bottom rim of the guide portion 131 and can be arranged around the guide portion 131. The rim portion 132 can be in the shape of a flange 122 formed at the bottom rim of the guide portion 131 or can be in the same direction as the conical surface 130 of the guide portion 131. The rim portion 132 is provided with a discharge opening 101 adapted to the bearing 92. The discharge opening 101 allows a single bearing 92 to leak out in a specific posture. The feeding cylinder 12 is in the shape of a ring and is sleeved outside the rim portion 132. The feeding cylinder 12 and the feeding base 13 jointly define a feeding cavity 120. The feeding cavity 120 is used to contain a plurality of bearings 92. The feeding opening of the feeding cavity 120 is upward. The discharge opening 101 is at the bottom of the feeding cavity 120. The conical surface 130 of the guide portion 131 is inclined relative to the horizontal plane. This allows the bearings 92 in the feeding cavity 120 to move toward the rim portion 132 under the action of gravity. The stirring member 14 extends into the feeding cavity 120. The stirring driving member 11 can drive the stirring member 14 to move circumferentially around the central axis of the guide portion 131 to stir the bearings 92 in the feeding cavity 120 to move around the central axis of the guide portion 131. This allows a constant number of bearings 92 to leak out through the discharge opening 101 in a specific posture.

[0056] Optionally, the stirring member 14 can be connected to the feeding cylinder 12. The stirring driving member 11 can drive the feeding cylinder 12 to rotate. The feeding cylinder 12 can drive the stirring member 14 to move circumferentially synchronously during rotation. In this way, the feeding cylinder 12 can drive the bearings 92 in the feeding cavity 120 to move by friction to increase the number of bearings 92 moving around the guide portion 131 and improve the efficiency of the bearings 92 leaking out one by one from the discharge opening.

[0057] Further, the stirring member 14 is above the rim portion 132. The distance between the stirring member 14 and the rim portion 132 is greater than or equal to the diameter of a single bearing 92. In this way, the stirring member 14 can avoid stirring away the bearings 92 about to leak out through the discharge opening 101. The stirring member 14 can be a screw. The top of the feeding cylinder 12 can be provided with a flange 122. The screw of the stirring member 14 can be arranged at the flange 122 to be inserted into the feeding cavity 120 from top to bottom.

[0058] Please refer to Figure 8Optionally, the discharge port 101 comprises a tapered hole 1011 and a lead-out hole 1012, the tapered hole 1011 is arranged above the lead-out hole 1012 and the width gradually decreases along the upward direction, so that the bearing 92 can roll into the lead-out hole 1012 along the hole wall of the tapered hole 1011, the lead-out hole 1012 is opened along the upward and downward direction, the cross section of the lead-out hole 1012 matches the cross section of the bearing 92, so that the bearing 92 leaks out in a specific posture. In this embodiment, the specific posture can be that the central axis of the hole 920 in the bearing 92 extends along the horizontal direction, the small ring is close to the central axis of the guide part 131 and the large ring is away from the central axis of the guide part 131.

[0059] Optionally, the material stirring driving member 11 has an output rod 111, the end of the output rod 111 is connected with a driving rod 112, the output rod 111 extends along the upward and downward direction, the extending direction of the driving rod 112 is perpendicular to the extending direction of the output rod 111, the central axis of the output rod 111 coincides with the central axis of the guide part 131, the top surface of the barrel 12 is convexly provided with a limiting convex 121, when the output rod 111 is driven to rotate by the material stirring driving member 11, the driving rod 112 rotates and can push the limiting convex 121 to move circumferentially, the limiting convex 121 drives the barrel 12 to rotate. In this way, the material stirring driving member 11 can be independent of the barrel 12, when the material is needed, the material stirring driving member 11 can be moved away to avoid blocking the opening of the material cavity 120. The limiting convex 121 can be a screw. In order to improve the stability of the driving rod 112 stirring the barrel 12, the limiting convex 121 can be provided with two, the connecting line of the two limiting convexes 121 passes through the central axis of the guide part 131, the two ends of the driving rod 112 can respectively stir the two limiting convexes 121. Of course, in other embodiments, the material stirring driving member 11 can also be fixedly connected with the barrel 12, which is not limited here.

The guide 21 is further provided with a first avoiding hole 202 penetrating through the inner wall of the guide channel 201 in the left-right direction and penetrating through the end face where the outfeed opening 2012 is located and the end face where the infeed opening 2011 is located, i.e., the guide channel 201 forms an aperture through the first avoiding hole 202, and the operator can observe whether the bearing 92 in the guide channel 201 is fully filled through the aperture, and the central axis of the bearing 92 in the guide channel 201 extends in the left-right direction, the first avoiding hole 202 is opposite to the center hole 920 of the bearing 92 in the guide channel 201 in the left-right direction, and the aperture width of the first avoiding hole 202 is smaller than the diameter of the bearing 92 to avoid the bearing 92 from leaking out of the first avoiding hole 202. The side of the guide 21 opposite to the first avoiding hole 202 is provided with a second avoiding hole 203 penetrating through the inner wall of the guide channel 201, and the width of the second avoiding hole 203 is greater than or equal to the diameter of the bearing 92. When the positioning shaft 32 moves the bearing 92 at the outfeed opening 2012, the bearing 92 can move out of the guide channel 201 from the second avoiding hole 203 and rotate 90° to be sleeved on the positioning shaft 32. The second avoiding hole 203 provides an opening for the bearing 92 to move out of the guide channel 201.

[0061] Please refer to Figure 9 In some embodiments, the guide-in mechanism 20 further comprises a turnover piece 22 movably connected to the guide 21, and the turnover piece 22 has a limiting position and a turnover position. When the turnover piece 22 is at the limiting position, the turnover piece 22 can be clamped in the second avoiding hole 203 together with the guide 21 to hold the bearing 92 at the outfeed opening 2012, and when the turnover piece 22 is at the turnover position, the turnover piece 22 partially avoids the second avoiding hole 203 in the left-right direction to enable the turnover piece 22 to move from the limiting position to the turnover position when the positioning shaft 32 moves the bearing 92. When the positioning shaft 32 moves the bearing 92 in the direction from the first avoiding hole 202 to the second avoiding hole 203, the bearing 92 pushes the turnover piece 22 to move from the limiting position to the turnover position, the bearing 92 is turned 90° to be sleeved on the positioning shaft 32 and moves out of the guide channel 201 from the second avoiding hole 203.

[0062] Optionally, the turnover member 22 is rotationally connected to the guide member 21, and specifically, the turnover member 22 is rotationally connected to the wall of the second avoiding hole 203 through a rotation shaft 221, so as to be conveniently arranged.

[0063] Further, when the turnover member 22 rotates, not only the lower half of the turnover member 22 can avoid the second avoiding hole 203 so that the bearing 92 at the discharging opening 2012 moves out of the guide channel 201, but also the upper half of the turnover member 22 can rotate to extend into the guide channel 201, so as to limit the second last bearing 92 in the guide channel 201 from moving downward, thereby avoiding that when the lowermost bearing 92 moves out of the second avoiding hole 203, the second last bearing 92 also moves out of the second avoiding hole 203 or is stuck with the turnover member 22 in the process of moving downward, so as to improve the reliability of the guide-in mechanism 20.

[0064] In other embodiments, the turnover member 22 can also be flexibly connected to the guide member 21 or slidingly connected to the guide member 21, which is not limited here.

[0065] Optionally, the guide-in mechanism 20 further comprises a first elastic member 23 connected between the guide member 21 and the turnover member 22, and the first elastic member 23 can exert an elastic force on the turnover member 22 to rotate toward the limiting position when the turnover member 22 rotates toward the turnover position. When the turnover member 22 is moved to the turnover position under the pushing action of the bearing 92, the turnover member 22 can be reset to the limiting position by the elastic force of the first elastic member 23, so as to realize the automatic reset of the turnover member 22. Of course, in other embodiments, the turnover member 22 can also be reset by its own gravity or magnetic attraction, which is not limited here.

[0066] Further, the first elastic member 23 can be a rubber ring, which is sleeved on the guide-in mechanism 20 and sleeves the guide member 21 and the turnover member 22 together, so as to be conveniently processed and replaced.

[0067] In other embodiments, the guide-in mechanism 20 can also not be provided with the turnover member 22, and the bearing 92 abuts against the inner wall of the first avoiding hole 202 on the side of the guide channel 201. Alternatively, the second avoiding hole 203 is not provided, and the first avoiding hole 202 can be used for the bearing 92 at the discharging opening 2012 to rotate 90° to move out of the guide channel 201, which is not limited here. In the above case, the extension direction of the guide channel 201 can also not be the vertical direction perpendicular to the horizontal plane, but a smaller angle with the vertical direction, and at this time, the extension direction of the guide channel 201 can still be considered as extending along the up-down direction.

[0068] Please refer to Figure 1Optionally, the infeeding mechanism 20 also includes an air blowing element 24, which enables an airflow to form within the guide channel 201 from the feed opening 2011 to the discharge opening 2012. After the bearing 92 exits from the discharge port 101 of the feeding mechanism 10, it enters the feed opening 2011 of the guide channel 201. Its movement toward the discharge opening 2012 can be propelled by its own gravity and the airflow from the air blowing element 24, thus preventing the bearing 92 from getting stuck in the guide channel 201.

[0069] Please see Figure 2 In some embodiments, the feeding mechanism 20 further includes a propulsion drive 25, which is capable of driving the guide 21 at the discharge port 101 of the feeding mechanism 10 (in conjunction with...). Figure 7 The guide 21 moves between the feeding position below and the guide position on the moving path of the positioning shaft 32. When the guide 21 is in the feeding position, the feeding opening 2011 of the guide channel 201 is located below the discharge port 101 of the feeding mechanism 10. When the guide 21 is in the guide position, the top of the positioning shaft 32 is aligned with the central hole 920 of the lowest bearing 92 in the guide channel 201 in the left-right direction during the movement. The pushing drive component includes, but is not limited to, cylinders, electric push rods, linear motors, hydraulic cylinders, etc.

[0070] Please see Figure 10 In some embodiments, the traveling mechanism 30 further includes a traveling drive 33, which can drive the riveting piece 31 to move in the left-right direction. The positioning shaft 32 can move in the through hole 310 of the riveting piece 31 as the riveting piece 31 moves. When the positioning shaft 32 moves the bearing 92, the top end of the positioning shaft 32 is opposite to the middle hole 920 of the bearing 92 to be moved in the left-right direction, so that the bearing 92 can be sleeved on the positioning shaft 32 after flipping. The traveling drive 33 can also drive the riveting piece 31 to move below the pressure head 42 after the positioning shaft 32 has sleeved the bearing 92, so that the pressure head 42 can rivet the bearing 92.

[0071] Please see Figure 11In some embodiments, the traveling mechanism 30 further comprises a jacking device 34, which comprises a jacking base 341, a jacking inner core 342 and a second elastic member 343. The jacking inner core 342 is slidably connected to the jacking base in the up-down direction. The second elastic member 343 is connected between the jacking base 341 and the jacking inner core 342. The jacking inner core 342 stays at a supporting position under the elastic force of the second elastic member 343. The jacking inner core 342 is used to support the lower surface of the casing 91, so that the lower surface of the casing 91 is spaced apart from the riveting member 31. When the casing 91 is sleeved on the traveling mechanism 30, the open end edge of the casing 91 can abut against the jacking inner core 342, and the inner surface of the barrel bottom of the casing 91 can be spaced apart from the riveting member 31. Then, when the bearing 92 is pressed by the pressing head 42, the bearing 92 can push the jacking inner core 342 to move downward relative to the jacking base to leave the supporting position through the casing 91, until the small annular ring of the bearing 92 abuts against the riveting member 31. The pressing head 42 and the riveting member 31 together rivet the small annular ring of the bearing 92 to the inner surface of the barrel bottom of the bearing 92. After the pressing head 42 is removed, the jacking inner core 342 can move upward and reset to the supporting position under the elastic force of the second elastic member 343. The jacking device 34 can make the barrel bottom of the casing 91 be spaced apart from the riveting member 31, so that the bearing 92 can pass through the riveting hole 910 on the casing 91. Thus, the small annular ring of the bearing 92 can be riveted to the inner surface of the barrel bottom of the bearing 92 when the pressing head 42 is pressed.

[0072] Please refer to Figure 11 In some embodiments, the traveling mechanism 30 further comprises a riveting seat 35 and a magnetic member 36.

The magnetic member 36 is connected to the riveting seat 35 and can be magnetically matched with the riveting member 31. The riveting seat 35 is connected to the supporting frame 80. The riveting member 31 has a riveting position and a magnetic position. When the riveting member 31 is at the magnetic position, the riveting member 31 is magnetically matched with the magnetic member 36 and is spaced apart from the supporting frame 80. When the riveting member 31 is at the riveting position, the riveting member 31 is separated from the magnetic member 36 and abuts against the supporting frame 80. When the pressing head 42 is pressed toward the bearing 92, the pressing head 42 pushes the riveting member 31 to move from the magnetic position to the riveting position through the bearing 92. At this time, the supporting frame 80 supports the riveting member 31, so that the riveting member 31 can rivet the bearing 92. After the pressing head 42 is removed, the riveting member 31 is reset to the magnetic position under the magnetic attraction of the magnetic member 36, in preparation for the next riveting operation. In this way, the pressure applied by the pressing head 42 to the riveting member 31 can be shared by the supporting frame 80, so that the pressure that the riveting seat 35 needs to bear is reduced, thereby reducing the influence on the reliability of the traveling mechanism 30.

[0073] The rivet 31 can be a metal piece or a magnetic piece, as long as it can be magnetically attracted to the magnet 36 and the machine shell 91. The driving piece 33 is connected to the rivet seat 35 and drives the rivet 31 to move by driving the rivet seat 35 to move.

The limiting block 3411 is used to limit the inner core 342 of the elastic top to the support position, so as to prevent the inner core 342 of the elastic top from being separated from the elastic top base 341. The spring is located in the elastic top hole 3410, and the two ends of the spring abut against the rivet seat 35 and the inner core 342 of the elastic top.

Among them, the magnet 36 can be provided with a plurality of magnets to improve the magnetic attraction force on the rivet 31. In this embodiment, the magnet 36 is provided with four magnets, and the four magnets 36 are arranged at equal intervals around the rivet 31 in the circumferential direction.

[0077] Optionally, the support frame 80 can be provided with a support rod 81 located below the rivet 31. When the pressing head 42 presses the rivet 31, the rivet 31 can abut against the support rod 81, and the support rod 81 can be made of a high-hardness material to prolong the service life. When the support rod 81 is severely damaged, the support rod 81 can be directly replaced without replacing the entire support frame 80.

[0078] In other embodiments, the advancing mechanism 30 can also not be provided with the elastic top 34, or not be provided with the rivet seat 35 and the magnet 36, which is not limited here.

The moving piece 52 can take the casing 91 off the traveling mechanism 30 as the press head 42 is moved up. The blanking mechanism 50 is used to realize the blanking of the casing 91 assembled with the bearing 92. The way the moving piece 52 holds the casing 91 includes but is not limited to clamping, vacuum adsorption, magnetic adsorption, etc.

[0080] Optionally, the moving piece 52 comprises a first clamping jaw 521 and a second clamping jaw 522.

The moving piece 52 can clamp the casing 91 when it is in the clamping state, and at least one clamping jaw can be away from the casing 91 when it is in the loosening state. After the press head 42 completes riveting and pressing of the bearing 92, the moving piece 52 can be switched to the clamping state to clamp the casing 91, and then the moving piece 52 moves the casing 91 upward to the positioning shaft 32 as the press head 42 is moved up. Then the traveling driving piece 33 can drive the riveting seat 35 to reset, in preparation for the sleeve connection of the next casing 91.

[0081] Optionally, the blanking mechanism 50 further comprises a suction accessory 53. The first clamping jaw 521 can be moved from a first position to a second position when the moving piece 52 is switched from the clamping state to the loosening state. The suction accessory 53 has a suction state and a release state. The suction accessory 53 can be switched to the suction state when the moving piece 52 is in the clamping state, and can be switched to the release state when the first clamping jaw 521 is moved to the second position. After the moving piece 52 is switched to the clamping state and clamps the casing 91, the suction accessory 53 is switched to the suction state, so that the casing 91 is adsorbed on the first clamping jaw 521. After the riveting seat 35 moves away from below the casing 91, the moving piece 52 is switched to the loosening state, the first clamping jaw 521 is moved from the first position to the second position, and at this time the casing 91 can also be moved to the second position under the adsorption of the suction accessory 53. Then the suction accessory 53 is switched to the release state, and the casing 91 falls off from the first clamping jaw 521, realizing unloading.

[0082] Optionally, the riveting all-in-one machine can further be provided with a discharging chute 60 below the second position.

The advancing driving member 33 is used to drive the fixed plate 83 to slide along the slide rails 82. In order to improve the assembly efficiency, two sets of advancing mechanisms 30 can be connected to the fixed plate 83, and correspondingly, two sets of riveting mechanisms 40 and discharging mechanisms are also provided to simultaneously realize the riveting of the two sets of machine housings 91 and bearings 92.

[0085] Please refer to Figure 13 and Figure 14 The riveting integrated machine can also insert the cylindrical bearing into the riveting hole of the machine housing. Please refer to Figure 15 When the bearing 92 is cylindrical, the working process of the riveting integrated machine includes: first, the bearing 92 in the leading-in mechanism 20 is sleeved into the positioning shaft 32 through the left-right movement of the advancing mechanism 30, and then the machine housing 91 is sleeved, at this time, the bearing 92 is located in the inner cavity of the machine housing 91 and abuts against the top surface of the riveting piece 31. When the pressing head 42 is pressed down (please refer to Figure 1 ), the pressing head 42 contacts the machine housing 91 and extrudes the machine housing 91 downward until the cylindrical bearing 92 is inserted into the riveting hole 910 of the machine housing 91. It can be seen that the riveting integrated machine can adapt to the assembly of the bearing 92 and the machine housing 91 in two different types of motors, has strong universality and is suitable for flexible production.

[0086] In the above embodiments, in order to ensure that the bearing 92 can be pressed into the riveting hole 910, no relief groove is formed on the top surface of the riveting piece 31, so as to provide a large enough support area for the bearing 92 and avoid deformation of the bearing 92.
