[0047] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0048] Example: See Figure 1 - Fig.11 , a household appliance sheet metal riveting device, comprising a base 1 and a turntable 2 rotatably connected to the top of the base 1, a first motor 7 is installed inside the base 1, and an output end of the first motor 7 is fixedly connected to the center of the bottom of the turntable 2;

[0049] By controlling the first motor 7 to drive the turntable 2 to rotate clockwise for every quarter turn and pause, the turntable 3 is driven to rotate from the workpiece placement station to the stud 9 loading station, the riveting station and the separation station in sequence, and finally returns to the workpiece placement station.

[0050] Also includes:

[0051] A positioning mechanism is arranged inside the turntable 2 and is used for positioning the workpiece to be riveted. The positioning mechanism includes a plurality of turntables 3 rotatably connected inside the turntable 2 and a positioning slot 4 provided on the top of the turntable 3. The number of the positioning slots 4 is four, and the four positioning slots 4 are distributed in a circular array with the output end of the first motor 7 as the center; the turntable 3 is arranged through the turntable 2; a plurality of support columns 5 are fixedly connected inside the positioning slot 4, and a docking slot 6 is provided inside the support column 5. The positioning slot 4 is square, and the riveted workpiece is also square. The workpiece is adapted to the positioning slot 4. The number of the support columns 5 is four and they are distributed along a square track;

[0052] First, the staff places the workpiece inside the positioning groove 4 on the left, the workpiece just matches the positioning groove 4, the four riveting holes on the workpiece are vertically aligned with the docking grooves 6 on the four support columns 5, and the upper edge of the workpiece is at the same level as the upper edges of the turntable 3 and the turntable 2.

[0053] The docking feeding mechanism is arranged above the turntable 2 and is used to automatically transport the studs 9 for riveting to the riveting position. The docking feeding mechanism includes a first bracket 8 installed on the top of the base 1, a feeding rack 10 installed on the top of the first bracket 8, and a material guide component installed inside the first bracket 8; a moving groove 11 is opened inside the first bracket 8 along its horizontal direction, and a feeding groove 12 is also opened inside the first bracket 8 along its height direction, and a turning groove 13 inclined downward is provided between the moving groove 11 and the feeding groove 12; the studs 9 are stacked inside the feeding rack 10, and the feeding rack 10 and the moving groove 11 are connected. The interiors are connected, and the material guide assembly includes an electric push rod 14 installed inside the first bracket 8 and a driving bar 15 slidably connected inside the moving groove 11; the extended end of the electric push rod 14 is fixedly connected to one end of the driving bar 15, and the other end of the driving bar 15 is provided with a supporting component, and the supporting component includes an extension plate 16 slidably connected to the other end of the driving bar 15 along the height direction thereof and limit blocks 17 respectively fixed to both sides of the top of the extension plate 16; two limit grooves 18 are provided inside the driving bar 15, and the two limit grooves 18 are symmetrically arranged on both sides of the extension plate 16, and the limit blocks 17 are slidably connected inside the limit grooves 18;

[0054] After the workpiece is placed, the first motor 7 is controlled to drive the turntable 2 to rotate a quarter of a turn and then stop, driving the workpiece to rotate to the stud 9 loading position, that is, driving the workpiece to rotate to the bottom of the loading trough 12. At this time, one of the docking grooves 6 is located directly below the loading trough 12. By controlling the electric push rod 14 to extend, the driving bar 15 is driven to move along the inner wall of the moving groove 11 toward the loading trough 12, thereby driving the stud 9 at the front end of the driving bar 15 to move synchronously, and the top of the driving bar 15 limits the other studs 9 stacked in the vertical direction, so that the other studs 9 will not enter the moving groove 11. After the stud 9 at the front end of the driving bar 15 enters the steering groove 13, it will slide downward at an angle, and one end will be aligned with the inner wall of the loading trough 12. At the same time, the extension plate 16 slides downward under the action of its own gravity, thereby driving the bar 15 to continue to move, so that the inclined stud 9 is gradually supported. After the stud 9 is supported, it falls vertically along the loading chute 12, passes through the riveting hole on the workpiece and enters the docking groove 6. The head of the stud 9 abuts against the top of the workpiece, and then the electric push rod 14 is controlled to drive the driving bar 15 to reset, and at the same time, the turntable 3 is driven to rotate 90° through the linkage mechanism, driving the next riveting hole and the docking groove 6 to rotate to the bottom of the loading chute 12, repeating the above stud 9 loading steps, inserting the next stud 9 into the riveting hole and the docking groove 6, and in this cycle, four studs 9 are inserted into the corresponding riveting holes and the docking groove 6 in turn;

[0055] When the electric push rod 14 drives the driving bar 15 to reset, the extension plate 16 automatically moves up along the inclined surface of the steering groove 13 to the inside of the driving bar 15. When the driving bar 15 is completely reset, the bottom stud 9 arranged in the vertical direction falls to the front end of the driving bar 15, thereby facilitating the subsequent driving of the stud 9 to move.

[0056] A riveting mechanism, which is arranged above the turntable 2 and is used to press and rivet the stud 9 onto the workpiece, the riveting mechanism comprising a second bracket 19 mounted on the top of the base 1, a hydraulic cylinder 20 mounted inside the second bracket 19, and a pressing head 21 mounted at the extended end of the hydraulic cylinder 20;

[0057] After the stud 9 is completely loaded, the first motor 7 is controlled to drive the turntable 2 to rotate a quarter of a turn and then stop, driving the workpiece to rotate to the riveting station, that is, driving the workpiece to rotate to the bottom of the pressure head 21. At this time, one of the studs 9 is located directly below the pressure head 21. The pressure head 21 is driven downward by controlling the hydraulic cylinder 20 to rivet the stud 9 on the workpiece, and then the hydraulic cylinder 20 is controlled to drive the pressure head 21 to move up and reset, and then the turntable 3 is driven to rotate a quarter of a turn through the linkage mechanism and then stop, driving the next stud 9 to rotate to the bottom of the pressure head 21, and then driving the pressure head 21 to rivet the stud 9 on the workpiece, and this cycle is repeated to rivet the four studs 9 on the workpiece in turn.

[0058] The separation mechanism is arranged inside the base 1 and connected with the positioning mechanism, and is used to drive the riveted workpiece to separate from the positioning mechanism. The separation mechanism includes a movable groove 22 provided inside the turntable 3 and a linkage frame 23 provided inside the movable groove 22; a plurality of slide bars 24 are fixedly connected to the top of the linkage frame 23, and the slide bars 24 are also slidably connected to the inside of the docking groove 6; a lifting rod 25 is fixedly connected to the bottom of the linkage frame 23, and the bottom end of the lifting rod 25 extends to the outside of the turntable 3 and is fixedly connected with a gravity ball 26; a third bracket 27 is installed inside the base 1, and an arc-shaped adjustment platform 28 is installed on the top of the third bracket 27, and both ends of the adjustment platform 28 are provided with inclined grooves;

[0059] After the riveting is completed, the first motor 7 is controlled to drive the turntable 2 to rotate a quarter of a turn and then stop, driving the workpiece to rotate to the separation station, that is, driving the workpiece to rotate to the top of the adjustment platform 28. At this time, the turntable 3 is driven to rotate through the linkage mechanism. When the turntable 3 rotates, it drives the gravity ball 26 to revolve around the driven shaft 29 as the center. When the gravity ball 26 moves up along the inclined groove to the top of the adjustment platform 28, the linkage frame 23 is driven to move upward through the lifting rod 25, thereby driving the four slide bars 24 along the inner walls of their respective docking grooves 6. It moves upward synchronously, and then pushes the top of each stud 9 inside the docking groove 6, thereby pushing out the stud 9 and the workpiece together, so that the staff can remove the riveted workpiece, which solves the problem in the prior art that the stud 9 is difficult to remove after being riveted together with the workpiece. As the gravity ball 26 continues to rotate, the gravity ball 26 moves down along another inclined groove by its own gravity, thereby driving the linkage frame 23 and the sliding rod 24 to move down and reset through the lifting rod 25. After the linkage frame 23 is reset, it abuts against the inner wall of the bottom of the movable groove 22.

[0060] A linkage mechanism is arranged inside the base 1 and is used to drive the positioning mechanism to rotate. The linkage mechanism includes a driven shaft 29 fixed to the bottom center of the turntable 3, a one-way gear 30 installed outside the driven shaft 29, and a gear ring 31 rotatably connected to the inside of the base 1; the one-way gear 30 is meshed with the gear ring 31, and the adjustment platform 28 is not on the trajectory of the circular motion of the one-way gear 30, the driven shaft 29 and the gravity ball 26; a second motor 32 is also installed inside the base 1, and a driving gear 33 is installed at the output end of the second motor 32, the upper edge of the driving gear 33 is lower than the lower edge of the one-way gear 30, and the driving gear 33 is also meshed with the gear ring 31;

[0061] When the first motor 7 drives the turntable 2 to rotate clockwise, it drives the one-way gears 30 to revolve synchronously in the clockwise direction. Through the meshing effect with the ring gear 31, the one-way gear 30 also rotates counterclockwise, but the driven shaft 29 does not rotate at this time, so the turntable 3 does not rotate either. During the time when the turntable 2 stops rotating, the second motor 32 is controlled to drive the driving gear 33 to rotate clockwise, and then the ring gear 31 is also driven to rotate clockwise synchronously. The ring gear 31 drives the one-way gear 30 to rotate clockwise, thereby driving the driven shaft 29 and the turntable 3 to rotate clockwise. Only when the turntable 2 stops and each turntable 3 reaches the corresponding workstation, the turntable 3 is driven to rotate. The turntable 2 rotates to the position where the turntable 3 does not rotate.

[0062] Working principle: When in use, the staff first places the workpiece inside the positioning groove 4 on the left, the workpiece just coincides with the positioning groove 4, the four riveting holes on the workpiece are vertically aligned with the docking grooves 6 on the four support columns 5, and the upper edge of the workpiece is at the same horizontal height as the upper edges of the turntable 3 and the turntable 2. The first motor 7 is controlled to drive the turntable 2 to rotate a quarter of a turn and then stop, driving the workpiece to rotate to the stud 9 loading position, that is, driving the workpiece to rotate to the bottom of the loading trough 12. At this time, one of the docking grooves 6 is located directly below the loading trough 12. By controlling the electric push rod 14 to extend, the drive bar 15 is driven to move along the inner wall of the moving groove 11 toward the loading trough 12, thereby driving the stud 9 at the front end of the drive bar 15 to move synchronously, and the front end of the drive bar 15 After the stud 9 enters the steering groove 13, it will slide downwardly, and one end will abut against the inner wall of the feeding groove 12. At the same time, the extension plate 16 will slide downward under the action of its own gravity, thereby driving the bar 15 to continue to move, so that the inclined stud 9 is gradually supported. After the stud 9 is supported, it falls vertically along the feeding groove 12, passes through the riveting hole on the workpiece and enters the docking groove 6. The head of the stud 9 abuts against the top of the workpiece, and then the electric push rod 14 is controlled to drive the driving bar 15 to reset. At the same time, the turntable 3 is driven to rotate 90° through the linkage mechanism, driving the next riveting hole and the docking groove 6 to rotate to the bottom of the feeding groove 12, repeating the above-mentioned stud 9 loading steps, inserting the next stud 9 into the riveting hole and the docking groove 6, and repeating this cycle. Insert the four studs 9 into the corresponding riveting holes and docking grooves 6 in turn. After loading is completed, control the first motor 7 to drive the turntable 2 to rotate a quarter of a turn and then stop, drive the workpiece to rotate to the riveting station, that is, drive the workpiece to rotate to the bottom of the pressure head 21. At this time, one of the studs 9 is located directly below the pressure head 21, and the pressure head 21 is driven downward by controlling the hydraulic cylinder 20 to rivet the stud 9 on the workpiece, and then the hydraulic cylinder 20 is controlled to drive the pressure head 21 to move up and reset, and then the turntable 3 is driven to rotate a quarter of a turn through the linkage mechanism and then stop, drive the next stud 9 to rotate to the bottom of the pressure head 21, and then drive the pressure head 21 to rivet the stud 9 on the workpiece, and repeat this cycle, and rivet the four studs 9 on the workpiece in turn. After the riveting is completed, control the first The motor 7 drives the turntable 2 to rotate a quarter of a turn and then stops, driving the workpiece to rotate to the separation station, that is, driving the workpiece to rotate to the top of the adjustment platform 28. At this time, the turntable 3 is driven to rotate through the linkage mechanism. When the turntable 3 rotates, it drives the gravity ball 26 to revolve around the driven shaft 29. When the gravity ball 26 moves up along the inclined groove to the top of the adjustment platform 28, the linkage frame 23 is driven to move upward through the lifting rod 25, thereby driving the four slide bars 24 to move upward synchronously along the inner walls of their respective docking grooves 6, and then push the tops of the studs 9 inside the docking grooves 6, thereby ejecting the studs 9 and the workpiece together, so that the staff can remove the riveted workpiece, which solves the problem in the prior art that the studs 9 are difficult to remove after being riveted together with the workpiece.
