[0040] Example

[0041] In order to improve Figure 1 The press-fit rivet efficiency of the rotating shaft A including the metal sheet A1 and the rotating shaft body A2 is shown, which reduces the labor intensity of the operator. Figure 1 and Figure 2 As shown, the present application discloses a riveting machine, comprising a machine platform 10, a dividing plate 20 provided on the machine platform 10, and a loading space provided on the machine platform 10 along a counterclockwise direction around the dividing plate 20, a first riveting mechanism 30, a second riveting mechanism 40, a riveting pressing mechanism 50, a detection mechanism 60, and a transporting and unloading mechanism 70;

[0042] The edge of the indexing plate 20 is provided with six fixtures 21 in a circular array for carrying the rotating shaft components;

[0043] The first riveting mechanism 30 includes two rivet feeders 31 (the specific structure of which is known in the art and will not be described in detail herein) provided on the machine 10 for supplying rivets, two rivet picking assemblies 32 provided on the machine 10 between the two rivet feeders 31 and the indexing plate 20 for picking up rivets from the two rivet feeders 31, a first XYZ axis driving assembly 33 mounted above the two rivet feeders 31 and the two rivet picking assemblies 32, and two rivet loading assemblies 34 provided on the first XYZ axis driving assembly 33 for receiving the rivets picked up by the two rivet picking assemblies 32 and loading them onto the rotating shaft component.

[0044] The second riveting mechanism 40 has the same arrangement structure as the first riveting mechanism 30;

[0045] The riveting mechanism 50 includes a power assembly 51 provided on the machine platform 10 and a riveting head 52 provided below the power assembly 51 for pressing the rivet into the rotating shaft component;

[0046] The detection mechanism 60 includes a second XYZ-axis drive assembly 61 mounted on the machine 10 and a CCD detection camera 62 for performing riveting detection on the second XYZ-axis drive assembly 61 (the specific structure is known in the art and will not be described in detail in this application);

[0047] The material handling and unloading mechanism includes an XZ-axis driving assembly 71 mounted on the machine platform 10 and a rotating mechanical gripper 72 mounted on the XZ-axis driving assembly 71 for grasping and placing the rotating shaft component.

[0048] The principle of the above scheme is explained as follows:

[0049] The operator assembles the metal sheet and the shaft body at the loading position and places them on the jig 21;

[0050] When the jig 21 of the indexing plate 20 reaches the first rivet installation mechanism 30, the two rivet picking assemblies 32 respectively pick up a rivet from the two rivet feeders 31. Driven by the first XYZ axis driving assembly 33, the two rivet picking assemblies 32 respectively put the picked up rivets into the rivet loading assembly 34. Driven by the first XYZ axis driving assembly 33, the rivet loading assembly 34 goes above the jig 21 and installs the two rivets in the two rivet holes of the metal sheet and the rotating shaft body respectively.

[0051] When the indexing plate 20 drives the jig 21 to the second rivet loading mechanism 40, the two rivet picking assemblies 32 respectively pick up a rivet from the two rivet feeders 31. Driven by the first XYZ axis driving assembly 33, the two rivet picking assemblies 32 move along the XYZ axis and place the picked up rivets into the rivet loading assembly 34 respectively. Driven by the first XYZ axis driving assembly 33, the rivet loading assembly 34 moves along the XYZ axis to the top of the jig 21 and installs the two rivets into the other two rivet holes on the metal sheet and the rotating shaft body respectively.

[0052] When the jig 21 of the indexing plate 20 reaches the riveting mechanism 50, the power assembly 51 drives the riveting head 52 to descend and press all four rivets into the four rivet holes on the metal sheet and the rotating shaft body at one time;

[0053] When the fixture 21 of the indexing plate 20 reaches the detection mechanism 60, the second XYZ axis driving assembly 61 drives the CCD detection camera to move along the XYZ axis to detect the rotating shaft to determine whether there is any missing assembly;

[0054] When the indexing plate 20 fixture 21 reaches the transport and unloading mechanism 70, the XZ axis driving assembly 71 drives the rotating mechanical gripper 72 to move along the XZ axis direction to sort and unload the qualified products and the unqualified rotating shafts.

[0055] refer to Figure 3 and Figure 4As shown, the fixture 21 of the present application includes a base plate 211 and a supporting block 212, two strong magnets 2111 fixed to the indexing plate 20 are respectively provided on both sides of the Y axis of the base plate 211, four guide posts 213 are respectively provided on the four sides of the upper part of the base plate 211, and guide holes (not marked) are respectively opened inside the four sides of the supporting block 212. The supporting block 212 is arranged above the base plate 211 and allows the four guide posts 213 to pass through the four guide holes respectively. The four guide posts 213 are respectively provided with springs 214 under the supporting block 212, and U-force rubber heads 2131 are respectively provided on the tops of the four guide posts. A first positioning support block 215 and a second positioning support block 216 perpendicular to each other are provided above the supporting block 212, and two positioning pins 21 are distributed on the first positioning support block 215. 51. Four rivet avoidance holes 2152 are also distributed on the first positioning support block 215. A support block 217 is provided above the bottom plate 211. Four ejector pins 2171 are provided above the support block 217 and extend into the four rivet avoidance holes 2152 respectively. In the specific implementation, the operator first places the metal sheet and the rotating shaft body to be assembled on the jig 21 and passes the positioning pin 2151 through the metal sheet and the rotating shaft body to position the two. When the jig 21 reaches the riveting mechanism 50, the power component 51 drives the riveting head 52 to descend and contact the four rivets. In the process of the power component 51 driving the riveting head 52 to continue to descend, the support block 212 elastically decreases under the action of the four springs 214. When the four rivets contact the four ejector pins 2171, it indicates that the riveting work is completed.

During the rivet picking process, the first Z-axis cylinder 321 drives the T-shaped plate 322 to descend, and when the electromagnetic suction head 323 contacts the rivet on the rivet feeder 31, it can automatically adsorb it. It should be noted here that the piston rod of the first Z-axis cylinder 321 of the present application is in an extended state in the initial state.

The plate 335 is arranged on the first Z-axis servo screw module 334. Under the drive of the first X-axis servo screw module 331, the first Y-axis servo screw module 333 moves along the X-axis direction on the first X-axis servo screw module 331 and the first X-axis linear guide 332. Under the drive of the first Y-axis servo screw module 333, the first Z-axis servo screw module 334 moves along the Y-axis. When the first Z-axis servo screw module 334 drives the slide plate 335 to move along the Z-axis, the two rivet loading assemblies 34 can move along the Z-axis direction.

[0061] In the second step, when the first XYZ-axis driving assembly 33 drives the rivet loading assembly 34 to the receiving position, the X-axis cylinder 346 drives the push plate to extend so that the receiving hole of the duckbill rivet head 348 is directly below the two electromagnetic suction heads 323. When the two electromagnetic suction heads 323 are powered off, the two rivets will automatically fall into the duckbill rivet head 348;

[0062] In the third step, when the first XYZ-axis driving assembly 33 drives the rivet loading assembly 34 to reach the material connection position, the two second Z-axis cylinders 342 drive the two pressing needles 343 to descend through the rivet holes of the two duckbill rivet heads 348.
