Description

Technical Field

[0001] This application relates to the technical field of riveting machines, and in particular to a riveting machine that facilitates material turning. Background Technology

[0002] A core is formed by pressing and riveting several silicon steel sheets together to form a complete unit. After the silicon steel sheets are pressed and riveted into a core, the cores are stacked neatly in sequence to facilitate later packaging and transportation. A riveting machine is a mechanical device that uses pressure equipment (such as hydraulic or pneumatic power sources) to apply pressure to rivets based on the cold rolling principle, so as to firmly connect the rivets to the workpiece.

[0003] Regarding the aforementioned technologies, the inventors believe that in actual production processes, it is often necessary to process workpieces that require riveting on multiple sides. However, after completing the riveting of one side with a traditional riveting machine, the workpiece needs to be manually flipped over and repositioned in the working area of ​​the riveting machine for the riveting of the other side. This manual flipping method is inefficient, labor-intensive, and can easily lead to workpiece position deviation during the flipping process, affecting the riveting accuracy. Therefore, to solve the above problems, this application provides a riveting machine that facilitates material flipping. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, this application provides a riveting machine that facilitates material turning.

[0005] This application provides a riveting machine for easy material turning, comprising a processing table, two vertical plates, a spacing adjustment assembly, and a riveting assembly. Each of the two vertical plates has a rotating rod rotatably connected to its opposite side via bearings. A U-shaped plate is fixedly connected to the end of each rotating rod away from the vertical plate. A first electric telescopic rod is fixedly connected to the top wall of the U-shaped plate. A pressure plate is fixedly connected to the output end of the first electric telescopic rod. A drive motor is fixedly connected to the outer wall of one of the vertical plates. A half-gear is fixedly connected to the output end of the drive motor via a coupling. A driven gear meshes with the outside of the half-gear. One end of one of the rotating rods passes through the vertical plate and is fixedly connected to the driven gear.

[0006] Preferably, the spacing adjustment component includes a horizontal groove formed on the surface of the processing table, a servo motor is fixedly connected to the inner wall of one end of the horizontal groove, a lead screw is fixedly connected to the output end of the servo motor through a coupling, a slider is threadedly connected to the external thread of the lead screw, and the top of the slider is fixedly connected to one of the vertical plates.

[0007] Preferably, the riveting assembly includes an L-shaped plate fixedly connected to the surface of the processing table, a second electric telescopic rod fixedly connected to the top inner wall of the L-shaped plate, and a riveting block fixedly connected to the output end of the second electric telescopic rod.

[0008] Preferably, a third electric telescopic rod is fixedly connected to the surface of the processing table and directly below the U-shaped plate away from the transverse groove, and a support plate is fixedly connected to the output end of the third electric telescopic rod.

[0009] Preferably, the vertical plate away from the slider is fixedly connected to the surface of the processing table.

[0010] Preferably, one of the outer walls of the pressure plate is in close contact with the inner wall of the U-shaped plate, and at least one outer wall of the slider is in close contact with the inner wall of the transverse groove.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] The distance between the two U-shaped plates can be adjusted using the spacing adjustment component, allowing for clamping and fixing of workpieces of different lengths according to their length. The workpiece's two side edges are placed at the bottom edge of the U-shaped plate. The first electric telescopic rod moves the pressure plate towards the workpiece, thus clamping and fixing it. The servo motor sequentially drives the half gear, driven gear, rotating rod, and U-shaped plate to rotate intermittently. The U-shaped plate rotates the workpiece 180 degrees with a pause, allowing for automatic workpiece flipping. Compared to existing technologies, this application not only clamps and fixes workpieces of different lengths but also automatically flips them, reducing manual flipping time and labor intensity, and significantly shortening the entire riveting process cycle.

[0019] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0020] Example 1:

[0021] A riveting machine that facilitates material flipping, see reference. Figure 2 , Figure 3 and Figure 5 It includes a processing table 1, two vertical plates 2, a spacing adjustment component and a riveting component. The two vertical plates 2 are rotatably connected to a rotating rod 3 on opposite sides via bearings. A U-shaped plate 4 is fixedly connected to the end of the rotating rod 3 away from the vertical plate 2. A first electric telescopic rod 5 is fixedly connected to the top wall of the U-shaped plate 4. A pressure plate 6 is fixedly connected to the output end of the first electric telescopic rod 5. One of the vertical plates 2 has a drive motor 7 fixedly connected to its outer wall. The output end of the drive motor 7 is fixedly connected to a half gear 8 via a coupling. The half gear 8 is externally engaged with a driven gear 9. One end of a rotating rod 3 passes through the vertical plate 2 and is fixedly connected to the driven gear 9. First, the distance between the two vertical plates 2 is adjusted by the spacing adjustment component. The two sides of the workpiece are placed at the bottom edge of the U-shaped plate 4. By activating the first electric telescopic rod 5, the first electric telescopic rod 5 drives the pressure plate 6 to move towards the workpiece, thereby clamping and fixing the workpiece. By activating the drive motor 7, the drive motor 7 drives the half gear 8 to rotate. The diameters of the half gear 8 and the driven gear 9 are equal. The rotation of the half gear 8 drives the driven gear 9, the rotating rod 3, and the U-shaped plate 4 to rotate 180 degrees and then pause for a period of time. This allows the processed workpiece to be flipped, realizing automatic flipping of the workpiece, reducing the time and labor intensity of manual flipping, and greatly shortening the entire riveting processing cycle.

[0022] Reference Figure 1 , Figure 2 and Figure 4The spacing adjustment component includes a horizontal groove 10 formed on the surface of the processing table 1. A servo motor 11 is fixedly connected to the inner wall of one end of the horizontal groove 10. A lead screw 12 is fixedly connected to the output end of the servo motor 11 through a coupling. A slider 13 is threadedly connected to the outside of the lead screw 12. The top of the slider 13 is fixedly connected to one of the vertical plates 2. When the servo motor 11 is started, the servo motor 11 drives the lead screw 12 to rotate. The rotation of the lead screw 12 drives the slider 13 to move outside, thereby driving the vertical plate 2 connected to the slider 13 to move towards the other vertical plate 2, so as to adjust the distance between the two vertical plates 2. The distance between the two U-shaped plates 4 can also be adjusted, so as to adjust the distance between the two U-shaped plates 4 according to the length of the workpiece, so as to achieve clamping and fixing of workpieces of different lengths.

[0023] Reference Figure 1 , Figure 2 and Figure 3 The riveting assembly includes an L-shaped plate 14 fixedly connected to the surface of the processing table 1. A second electric telescopic rod 15 is fixedly connected to the top inner wall of the L-shaped plate 14. A riveting block 16 is fixedly connected to the output end of the second electric telescopic rod 15. By activating the second electric telescopic rod 15, the movement of the second electric telescopic rod 15 will drive the riveting block 16 to move towards the workpiece, thereby realizing the riveting operation on the workpiece.

[0024] Reference Figure 1 and Figure 5 A third electric telescopic rod 17 is fixedly connected to the surface of the processing table 1 and directly below the U-shaped plate 4 away from the transverse groove 10. The output end of the third electric telescopic rod 17 is fixedly connected to a support plate 18. When riveting the workpiece, the third electric telescopic rod 17 is activated to drive the support plate 18 to move until the support plate 18 contacts the bottom of the U-shaped plate 4, so as to prevent the U-shaped plate 4 from shifting when riveting the workpiece. When the U-shaped plate 4 rotates, the third electric telescopic rod 17 retracts to drive the support plate 18 to descend, so as to prevent the support plate 18 from obstructing the rotation of the U-shaped plate 4.

[0025] Reference Figure 1 and Figure 2 The vertical plate 2, which is away from the slider 13, is fixedly connected to the surface of the processing table 1.

[0026] Reference Figure 3 and Figure 5 One of the outer walls of the pressure plate 6 is tightly fitted to the inner wall of the U-shaped plate 4 to prevent the pressure plate 6 from rotating and shifting during movement. At least one outer wall of the slider 13 is tightly fitted to the inner wall of the transverse groove 10 to prevent the slider 13 from rotating and shifting when it moves outside the lead screw 12.

[0027] The implementation principle of a riveting machine for easy material turning in this application embodiment is as follows: The first electric telescopic rod 5, the second electric telescopic rod 15, and the third electric telescopic rod 17 are all preferably of the LX600 model. The first electric telescopic rod 5, the drive motor 7, the servo motor 11, the second electric telescopic rod 15, and the third electric telescopic rod 17 are all electrically connected to an external power supply via a switch. The drive motor 7 is preferably of the YE2132M-4 model. The drive motor 7 is started by the switch, and its operation drives the lead screw 12 to rotate. The external helical opening angle of the lead screw 12 is 20 degrees, and the thread self-locking condition is met. The following formula is used to calculate: Self-locking condition = coefficient of friction × tan(helix angle) ≥ 1. The rotation of the lead screw 12 drives the external slider 13 to move outside, thereby driving the vertical plate 2 connected to the slider 13 to move towards another vertical plate 2, which is used to adjust the distance between the two vertical plates 2. The distance between the two U-shaped plates 4 can be adjusted according to the length of the workpiece, so as to achieve clamping and fixing of workpieces of different lengths. The two sides of the workpiece are placed at the bottom edge of the U-shaped plate 4. The first electric telescopic rod 5 is started by the switch. The first electric telescopic rod 5 is activated by a switch. The first electric telescopic rod 5 drives the pressure plate 6 towards the workpiece, thereby clamping and fixing the workpiece. The second electric telescopic rod 15 is activated by a switch. The movement of the second electric telescopic rod 15 drives the riveting block 16 towards the workpiece, realizing the riveting operation. The servo motor 11, preferably an HBS57 type, is activated by a switch. The servo motor 11 drives the half gear 8 to rotate. The half gear 8 and the driven gear 9 have the same diameter. The rotation of the half gear 8 drives the driven gear 9, the rotating rod 3, and the U-shaped plate 4 to rotate one revolution per revolution. The 180-degree rotation will pause for a period of time, which can drive the processed workpiece to flip over, realizing the automatic flipping of the workpiece. When the workpiece is riveted, the third electric telescopic rod 17 is activated to drive the slide plate 18 to move until the slide plate 18 contacts the bottom of the U-shaped plate 4, so as to prevent the U-shaped plate 4 from shifting when the workpiece is riveted. When the U-shaped plate 4 rotates, the third electric telescopic rod 17 retracts and drives the slide plate 18 to descend, so as to prevent the slide plate 18 from obstructing the rotation of the U-shaped plate 4. The whole process reduces the time and labor intensity of manual flipping, and greatly shortens the entire riveting processing cycle.
