[0042] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0043] The embodiment of the present invention provides a riveting machine for riveting a bearing into a housing. Figure 3, the housing 91 is the housing 91 of the iron core micromotor, and the housing 91 is a cylindrical shape with one end open and one section closed, and the housing 91 forms an inner cavity, and the housing 91 is provided with a rivet hole 910 at the bottom of the cylinder, and the rivet hole 910 passes through the outer surface and the inner surface of the bottom of the cylinder of the housing 91, wherein the inner surface faces the inner cavity. The bearing 92 can be cylindrical or stepped, and both are suitable for the riveting all-in-one machine. In the following embodiments, the bearing 92 riveted to the housing 91 is first described as a stepped shape. Among them, the bearing 92 includes concentric small and large rings, and the small and large rings are arranged axially and form a middle hole 920 together. The central axis of the middle hole 920 coincides with the central axis of the small and large rings, and the size of the small ring matches the size of the rivet hole 910 at the bottom of the cylinder of the housing 91.

[0044] See also Figure 1 The riveting machine includes a feeding mechanism 10 , an introduction mechanism 20 , a traveling mechanism 30 and a riveting mechanism 40 .

[0045] The feeding mechanism 10 is used to export multiple bearings 92 one by one, the importing mechanism 20 is used to arrange multiple bearings 92 one by one along a preset path, the traveling mechanism 30 is used to take out a single bearing 92 of the importing mechanism 20, and stack the bearing 92 and the housing 91, and the riveting mechanism 40 is used to complete the riveting of the bearing 92 and the housing 91.

[0046] The feeding mechanism 10 has a feeding cavity 120 and a discharge port, wherein the feeding cavity 120 is used to hold a plurality of bearings 92, and the discharge port is connected to the feeding cavity 120 and is used to allow a single bearing 92 to leak out. The plurality of bearings 92 in the feeding cavity 120 leak out one by one through the discharge port.

[0047] Please combine Figure 2 The introduction mechanism 20 is provided with a guide channel 201 extending along a first direction, and the first direction can be selected as the up and down direction, that is, the guide channel 201 extends along a straight line perpendicular to the horizontal plane, and the two ends of the guide channel 201 in the up and down directions respectively form a feed opening 2011 and a discharge opening 2012, that is, the upper end of the guide channel 201 forms a feed opening 2011, and the lower end forms a discharge opening 2012, and the guide channel 201 can accommodate the bearings 92 leaking out of the discharge port 101 to be arranged one by one along the up and down directions, that is, the feed opening 2011 of the guide channel 201 is opposite to the discharge port of the feeding mechanism 10, and the bearings 92 leaking out of the discharge port enter the guide channel 201 one by one through the feed 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 discharge opening 2012 of the guide channel 201 may be slightly smaller than the diameter of the bearing 92, so that the lowest bearing 92 in the guide channel 201 is stuck at the discharge opening 2012 to prevent the bearing 92 in the guide channel 201 from leaking out of the discharge opening 2012, or, at least the lowest bearing 92 among the bearings 92 in the guide channel 201 is clamped or interference fit, as long as the lowest bearing 92 can be limited and does not affect the entry of other bearings 92 into the guide channel 201 housing 91.

[0049] Please combine Figure 3 and Figure 4 The travel mechanism 30 includes a rivet 31 and a positioning shaft 32. The housing 91 can be firstly put on the rivet 31, and the rivet 31 extends into the inner cavity of the housing 91. The top of the rivet 31 is opposite to the inner surface of the bottom of the housing 91. The positioning shaft 32 is penetrated in the rivet 31 along the up and down direction, that is, the rivet 31 is provided with a through hole 310 along the up and down direction, and the positioning shaft 32 is penetrated in the through hole 310 and passes through the riveting hole 910 of the housing 91. The traveling mechanism 30 can move along the second direction to make the positioning shaft 32 move the bearing 92 at the discharge opening 2012, so that the bearing 92 at the discharge opening 2012 escapes from the guide channel 201 and is sleeved on the positioning shaft 32. The bearing 92 falls on the outer surface of the bottom of the housing 91 along the positioning shaft 32 under the action of gravity. At this time, the small ring of the bearing 92 is located below the large ring. The small ring can be located outside the riveting hole 910 of the housing 91, or partially enter the riveting hole 910. The second direction is set at an angle to the first direction. In this embodiment, the second direction can be selected as the left and right direction, that is, the second direction is perpendicular to the first direction. The traveling mechanism 30 may also include a traveling drive 33. The movement of the riveted part 31 and the positioning shaft 32 can be realized by the traveling drive 33. The traveling drive 33 can provide power for the movement of the riveted part 31. The traveling drive 33 includes but is not limited to a cylinder, an electric push rod, a linear motor, a hydraulic cylinder, etc.

[0050] It should be noted that the introduction mechanism 20 avoids the positioning shaft 32 on the moving path of the positioning shaft 32 to avoid affecting the movement of the positioning shaft 32. The positioning shaft 32 can flip the lower half of the bearing 92 by its top, so that the bearing 92 leaks out from the discharge opening 2012 and is sleeved on the positioning shaft 32 through the middle hole 920. In order to facilitate the sleeve connection between the bearing 92 and the positioning shaft 32, the top of the positioning shaft 32 can be in a pointed cone shape. At the same time, after the bearing 92 at the discharge opening 2012 moves 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, so as to prepare for the next movement of the positioning shaft 32.

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

[0052] Please combine Figure 5 The riveting machine is provided with an introduction mechanism 20 so that a plurality of bearings 92 can be arranged in sequence, and then the bearing 92 at the discharge opening 2012 is moved by the positioning shaft 32, so that a single bearing 92 can be moved out of the introduction mechanism 20 and placed on the riveting hole 910 of the housing 91. The positioning shaft 32 can also realize the alignment of the bearing 92 and the riveting hole 910 on the housing 91, so that the pressure head 42 can directly rivet the bearing 92 to the riveting hole 910 of the housing 91 by pressing down. In this way, the housing 91 and the bearing 92 are automatically riveted by the riveting machine without manual participation, saving manpower and processing costs, and improving production efficiency.

[0053] See also Figure 3 and Figure 4 Optionally, in order to avoid affecting the middle hole 920 of the bearing 92, an avoidance groove 3101 may be opened on the top surface of the rivet member 31, and the rivet member 31 rivets the edge portion of the small circular ring of the bearing 92 through the edge portion 132 of the side groove 3101. The avoidance groove 3101 is used to accommodate the main body of the small circular ring to avoid squeezing and deforming the middle hole 920 of the bearing 92.

[0054] See also Figure 1 In some embodiments, the riveting machine further includes a support frame 80, and the feeding mechanism 10, the introduction mechanism 20, the travel mechanism 30 and the riveting mechanism 40 are all connected to the support frame 80 to form an integrated structure.

[0055] See also Figure 6 and Figure 7In some embodiments, the feeding mechanism 10 includes a material-dispensing driving member 11, a barrel 12, a feeding base 13, and a material-dispensing member 14. The feeding base 13 includes a guide portion 131 and an edge portion 132. The guide portion 131 is truncated cone-shaped or conical. The guide portion 131 has a conical surface 130 arranged around the central axis. The central axis of the guide portion 131 extends in the up-down direction, and the bottom diameter of the guide portion 131 is greater than the top diameter. The edge portion 132 is connected to the bottom edge of the guide portion 131 and can be arranged around the guide portion 131. The edge portion 132 can form a flange 122-shaped structure at the bottom edge of the guide portion 131, or it can be in the same direction as the conical surface 130 of the guide portion 131, which is not limited here. The edge portion 132 is provided with a discharge port 101 adapted to the bearing 92, and the discharge port 101 allows a single bearing 92 to leak out in a specific posture. The barrel 12 is annular and sleeved outside the edge portion 132. The barrel 12 and the feed base 13 are jointly arranged to form a feed chamber 120. The opening of the feed port faces upward. The feed chamber 120 is used to hold a plurality of bearings 92. The discharge port 101 is located at the bottom of the feed chamber 120. Since the conical surface 130 of the guide portion 131 is inclined relative to the horizontal plane, the bearings 92 in the feed chamber 120 can move toward the edge portion 132 under the action of gravity. The material-digging member 14 extends into the feed chamber 120, and the material-digging driving member 11 can drive the material-digging rod to move in a circle around the central axis of the guide portion 131 to dig the bearings 92 in the feed chamber 120 to move around the central axis of the guide portion 131, so that the bearings 92 can continuously leak out through the discharge port 101 in a specific posture.

[0056] Optionally, the material shifting member 14 can be connected to the barrel 12, and the material shifting driving member 11 can drive the barrel 12 to rotate, and the barrel 12 can drive the material shifting member 14 to synchronously move in a circular motion during its rotation. In this way, the barrel 12 can drive the bearings 92 in the feed cavity 120 to move through friction, so as to increase the number of bearings 92 moving around the guide portion 131 and improve the efficiency of the bearings 92 leaking out of the discharge hole one by one. The shifting member can assist the barrel 12 in shifting, further increasing the shifting range.

[0057] Furthermore, the material-pickup member 14 is located above the edge portion 132, and the distance between the material-pickup member 14 and the edge portion 132 is greater than or equal to the large ring diameter of a single bearing 92, so that the material-pickup member 14 can prevent the bearing 92 that is about to leak out of the discharge port 101 from being pushed away. The material-pickup member 14 can be a screw, and a flange 122 can be provided at the top of the barrel 12. The screw serving as the material-pickup member 14 can be provided at the flange 122 so as to be inserted into the feed cavity 120 from top to bottom.

[0058] Please combine Figure 8Optionally, the discharge port 101 includes a tapered hole 1011 and an outlet hole 1012. The tapered hole 1011 is disposed above the outlet hole 1012, and its width gradually decreases from top to bottom, so that the bearing 92 can roll into the outlet hole 1012 along the hole wall of the tapered hole 1011. The outlet hole 1012 is extended in the up-down direction, and the cross section of the outlet hole 1012 matches the cross section of the bearing 92, so that the bearing 92 can leak out in a specific posture. In this embodiment, the specific posture can be a posture in which the central axis of the hole 920 in the bearing 92 extends in the horizontal direction, the small circle is close to the central axis of the guide portion 131, and the large circle is away from the central axis of the guide portion 131.

[0059] Optionally, the material-pickling driving member 11 has an output rod 111, and the end of the output rod 111 is connected to a driving rod 112, the output rod 111 extends in the up-down direction, the extension direction of the driving rod 112 is perpendicular to the extension direction of the output rod 111, the central axis of the output rod 111 coincides with the central axis of the guide portion 131, and a limiting protrusion 121 is convexly provided on the top surface of the barrel 12. When the material-pickling driving member 11 drives the output rod 111 to rotate, the driving rod 112 rotates and can push the limiting protrusion 121 to move in a circle, and the limiting protrusion 121 drives the barrel 12 to rotate. In this way, the material-pickling driving member 11 can be independent of the barrel 12, and when feeding is required, the material-pickling driving member 11 can be removed to avoid blocking the opening of the feeding chamber 120. Among them, the limiting protrusion 121 can be optionally a screw. In order to improve the stability of the driving rod 112 in moving the barrel 12, two limiting protrusions 121 can be provided, and the connecting line of the two limiting protrusions 121 passes through the central axis of the guide portion 131, and the two ends of the driving rod 112 can respectively move the two limiting protrusions 121. Of course, in other embodiments, the material-moving driving member 11 can also be fixedly connected to the barrel 12, which is not limited here.

Optionally, the guide channel 201 is provided with equal width in the up and down directions, and the limiting structure 211 is connected to the lower end surface of the guide member 21 and can block part of the discharge opening 2012 to prevent the bearing 92 from leaking from the discharge opening 2012, wherein the limiting structure 211 avoids the positioning shaft 32. The limiting structure 211 can be detachably connected to the guide member 21, or can be integrally formed with the guide member 21, which is not limited here. The guide member 21 is also provided with a first avoidance hole 202, which penetrates the inner wall of the guide channel 201 in the left-right direction, and penetrates the end face where the discharge opening 2012 and the feed opening 2011 are located, that is, the guide channel 201 forms a gap through the first avoidance hole 202, through which the operator can observe whether the bearing 92 in the guide channel 201 is fully loaded. The central axis of the bearing 92 in the guide channel 201 extends in the left-right direction. The first avoidance hole 202 is opposite to the middle hole 920 of the bearing 92 in the guide channel 201 in the left-right direction. The opening width of the first avoidance hole 202 is smaller than the diameter length of the bearing 92 to prevent the bearing 92 from leaking out of the first avoidance hole 202. A second avoidance hole 203 is provided on the side of the guide member 21 that is opposite to the first avoidance hole 202 and penetrates the inner wall of the guide channel 201. The width of the second avoidance hole 203 is greater than or equal to the diameter length of the bearing 92. When the positioning shaft 32 moves the bearing 92 at the discharge opening 2012, the bearing 92 can move out of the guide channel 201 from the second avoidance hole 203 and can be rotated 90° to be sleeved on the positioning shaft 32. The second avoidance hole 203 provides an opening for the bearing 92 to move out of the guide channel 201.

[0061] See also Fig. 9 In some embodiments, the introduction mechanism 20 further includes a flip member 22 movably connected to the guide member 21, and the flip member 22 has a limit position and a flip position. When the flip member 22 is at the limit position, the flip member 22 can clamp the bearing 92 at the discharge opening 2012 together with the guide member 21 in the second avoidance hole 203. When the flip member 22 is at the flip position, the flip member 22 partially avoids the second avoidance hole 203 in the left and right directions, so that the flip member 22 can move from the limit position to the flip position when the positioning shaft 32 moves the bearing 92. When the positioning shaft 32 moves the bearing 92 from the first avoidance hole 202 to the second avoidance hole 203, the bearing 92 pushes the flip member 22 to move from the limit position to the flip position, and the bearing 92 flips 90° to be sleeved on the positioning shaft 32, and moves out of the guide channel 201 from the second avoidance hole 203.

[0062] Optionally, the flip member 22 is rotatably connected to the guide member 21 . Specifically, the flip member 22 can be rotatably connected to the hole wall of the second avoidance hole 203 via a rotating shaft 221 for easy installation.

[0063] Furthermore, when the flip member 22 rotates, not only can the lower half of the flip member 22 avoid part of the second avoidance hole 203 to allow the bearing 92 at the discharge opening 2012 to move out of the guide channel 201, but the upper half of the flip member 22 can also rotate to extend into the guide channel 201 to limit the downward movement of the second-to-last bearing 92 in the guide channel 201, thereby preventing the lowest bearing 92 from moving out of the second avoidance hole 203, and preventing the second-to-last bearing 92 from also moving out of the second avoidance hole 203 or jamming the flip member 22 during the downward movement, thereby improving the reliability of the introduction mechanism 20.

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

[0065] Optionally, the introduction mechanism 20 further includes a first elastic member 23 connected between the guide member 21 and the flip member 22, and the first elastic member 23 can apply an elastic force to the flip member 22 to rotate toward the limit position when the flip member 22 rotates toward the flip position. When the flip member 22 moves to the flip position under the push of the bearing 92, the flip member 22 can be reset to the limit position by the elastic force of the first elastic member 23, thereby realizing the automatic reset of the flip member 22. Of course, in other embodiments, the flip member 22 can also be reset by its own gravity or magnetic attraction, which is not limited here.

[0066] Furthermore, the first elastic member 23 may be a rubber ring, which is sleeved on the introduction mechanism 20 and sleeves the guide member 21 and the flip member 22 together for easy processing and replacement.

[0067] In other embodiments, the introduction mechanism 20 may not be provided with the flipping member 22, and the bearing 92 may be against the inner wall of the first avoidance hole 202 side of the guide channel 201. Alternatively, the second avoidance hole 203 is not provided, and the first avoidance hole 202 allows the bearing 92 at the discharge opening 2012 to flip 90° and move out of the guide channel 201, which is not limited here. In the above case, the extension direction of the guide channel 201 may not be the vertical direction perpendicular to the horizontal plane, but may be at a smaller angle to the vertical direction. In this case, the extension direction of the guide channel 201 can still be regarded as extending in the up-down direction.

[0068] Please combine Figure 1Optionally, the introduction mechanism 20 further includes a blowing member 24, which can form an airflow from the feed opening 2011 to the discharge opening 2012 in the guide channel 201. The bearing 92 leaks out from the discharge opening 101 of the feed mechanism 10 and enters the feed opening 2011 of the guide channel 201. The movement of the bearing 92 toward the discharge opening 2012 can be driven by its own gravity and the airflow of the blowing member 24 to prevent the bearing 92 from being stuck in the guide channel 201.

[0069] See also Figure 2 In some embodiments, the introduction mechanism 20 further includes a propulsion drive 25, which can drive the guide member 21 to move toward the discharge port 101 (combined with the feed mechanism 10). Figure 7 ) below and the introduction position on the moving path of the positioning shaft 32. When the guide member 21 is at 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 member 21 is at the introduction position, the top end of the positioning shaft 32 is aligned with the middle hole 920 of the lowest bearing 92 in the guide channel 201 in the left-right direction during the movement. The driving member includes but is not limited to a cylinder, an electric push rod, a linear motor, a hydraulic cylinder, etc.

[0070] See also Fig.10 In some embodiments, the travel mechanism 30 further includes a travel drive 33, which can drive the rivet stamp 31 to move in the left-right direction, and the positioning shaft 32 can move in the through hole 310 of the rivet stamp 31 along with the movement of the rivet stamp 31. 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 turning over. The travel drive 33 can also drive the rivet stamp 31 to move below the pressure head 42 after the positioning shaft 32 is sleeved with the bearing 92, so that the pressure head 42 can rivet the bearing 92.

[0071] See also Fig.11In some embodiments, the travel mechanism 30 also includes a pop-up device 34, which includes a pop-up base 341, a pop-up core 342 and a second elastic member 343. The pop-up core 342 is slidably connected to the pop-up base along the up and down directions. The second elastic member 343 is connected between the pop-up base 341 and the pop-up core 342. The pop-up core 342 stays in a supporting position under the elastic force of the second elastic member 343. The pop-up 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 rivet 31. When the housing 91 is sleeved on the travel mechanism 30, the edge of the open end of the housing 91 can abut against the top spring core 342, and the inner surface of the bottom of the housing 91 can be spaced from the rivet stamp 31. Then, when the pressure head 42 embosses the bearing 92, the bearing 92 can push the top spring core 342 downward relative to the top spring base through the housing 91 to leave the supporting position until the small ring of the bearing 92 abuts against the rivet stamp 31, and the pressure head 42 and the rivet stamp 31 jointly rivet the small ring of the bearing 92 to the inner surface of the bottom of the bearing 92. After the pressure head 42 moves up, the top spring core 342 can move up and return to the supporting position under the elastic force of the second elastic member 343. The setting of the ejector 34 allows the bottom of the casing 91 to be spaced apart from the rivet stamp 31, so that the bearing 92 can pass through the riveting hole 910 on the casing 91. In this way, when the pressure head 42 is pressed, the small ring of the bearing 92 can be riveted to the inner surface of the bottom of the bearing 92.

When the rivet stamping member 31 is in the rivet stamping position, the rivet stamping member 31 is separated from the magnetic member 36 and abuts against the support frame 80. When the pressure head 42 is pressed toward the bearing 92, the pressure head 42 pushes the rivet stamping part 31 from the magnetic attraction position to the riveting position through the bearing 92. At this time, the support frame 80 supports the rivet stamping part 31, and the rivet stamping part 31 can rivet the bearing 92. After the pressure head 42 is removed, the rivet stamping part 31 is reset to the magnetic attraction position under the magnetic attraction of the magnetic member 36 to prepare for the next riveting action. In this way, the pressure applied by the pressure head 42 to the rivet stamping part 31 can be shared by the support frame 80, reducing the pressure that the rivet stamping seat 35 needs to bear, thereby reducing the impact on the reliability of the traveling mechanism 30.

[0073] The rivet stamping part 31 may be a metal part or a magnetic part, as long as it can achieve magnetic attraction with the magnetic attraction part 36 to match the housing 91.

After the moving member 52 switches to the clamping state and clamps the housing 91, the adsorption member 53 switches to the adsorption state so that the housing 91 is adsorbed on the first clamping jaw 521. After the riveting seat 35 leaves the bottom of the housing 91, the moving member 52 switches to the loosening state, and the first clamping jaw 521 moves from the first position to the second position. At this time, the housing 91 can also move to the second position under the adsorption action of the adsorption member 53, and then the adsorption member 53 switches to the release state, and the housing 91 falls from the first clamping jaw 521 to achieve unloading.
