[0024] The embodiment of the utility model provides an automatic riveting machine for beryllium copper wire.

[0025] See also Figure 1 , Figure 2 , Figure 3 and, Figure 4 and Figure 5 , including a frame 1, a push-pushing telescopic pneumatic cylinder 2, a copper wire body 8, a riveting telescopic hydraulic cylinder 3 and a cutting structure. An L-shaped plate 19 is arranged inside the frame 1, a double-axis pneumatic cylinder 15 is arranged inside the L-shaped plate 19, clamping frames 17 are installed at both ends of the double-axis pneumatic cylinder 15, and rubber plates 18 and blades 22 are fixedly connected inside the two clamping frames 17. A material-guiding telescopic pneumatic cylinder 13 is arranged on one side of the double-axis pneumatic cylinder 15, and a clamping structure is arranged on the outside of the L-shaped plate 19.

[0026] When the utility model is in use: a pressure plate 20 is fixedly connected between the L-shaped plate 19 and the frame 1, the position of the L-shaped plate 19 is installed and fixed by the pressure plate 20, and then one end of the copper wire body 8 is inserted into the L-shaped plate 19, and the copper wire body 8 is controlled to be located partially inside the L-shaped plate 19.

[0027] A material guiding telescopic pneumatic cylinder 13 is fixedly connected to one side of the L-shaped plate 19. The staff first controls the dual-axis pneumatic cylinder 15, the material guiding telescopic pneumatic cylinder 13 and the material clamping telescopic pneumatic cylinder 11 to work. The first to work is the material clamping telescopic pneumatic cylinder 11 in the clamping structure. The material clamping telescopic pneumatic cylinder 11 extends and pushes the connecting plate 12 fixedly connected at one end to move. In addition, two clamps 9 are provided on one side of the L-shaped plate 19, one clamp 9 is fixedly connected to the L-shaped plate 19, and a connecting plate 12 is fixedly connected between the other clamp 9 and the material clamping telescopic pneumatic cylinder 11. Therefore, after the material clamping telescopic pneumatic cylinder 11 pushes the clamp 9 to move through the connecting plate 12, the two clamps 9 fit together. At this time, the friction plates 10 fixedly connected inside the two clamps 9 clamp and fix the copper wire 8, and the copper wire 8 cannot move.

[0028] At this time, the double-axis pneumatic cylinder 15 is in the stripping position, and fixed bent plates 16 are fixedly connected at both ends of the double-axis pneumatic cylinder 15, and the two fixed bent plates 16 are fixedly connected to two clamping frames 17 respectively. The double-axis pneumatic cylinder 15 that works for the first time drives the two clamping frames 17 to move through the two fixed bent plates 16. During the process of both ends of the double-axis pneumatic cylinder 15 shrinking back into the inside of the double-axis pneumatic cylinder 15 at the same time, the double-axis pneumatic cylinder 15 drives the two clamping frames 17 to move through the two fixed bent plates 16, so that the rubber plate 18 fixedly connected inside the clamping frame 17 fits with the outer side of the copper wire body 8, and the two severely deformed rubber plates 18 clamp the outer side of the copper wire body 8, and at the same time, the blade 22 cuts the outer skin of the copper wire body 8 to cut off the outer skin of the copper wire body 8.

[0029] Subsequently, the first material-guiding telescopic pneumatic cylinder 13 extends and pushes the transmission plate 14 fixedly connected at the extension end to move. Since one end of the transmission plate 14 is fixedly connected to the outer shell of the double-axis pneumatic cylinder 15, the double-axis pneumatic cylinder 15 is pushed to move synchronously, and the double-axis pneumatic cylinder 15 drives the clamping frame 17 to move through the fixed bent plate 16.

[0030] Since the rubber plate 18 fixedly connected inside the clamping frame 17 is clamped on the outside of the cut-off part of the outer skin of the copper wire body 8, the cut-off outer skin of the copper wire body 8 is pulled away from the outside of the copper wire body 8, completing the local peeling work on the outside of the copper wire body 8. After the clamping frame 17 leaves the inside of the L-shaped plate 19, the double-axis pneumatic cylinder 15 works for the second time, and the double-axis pneumatic cylinder 15 pushes the two fixed bent plates 16 away from the copper wire body 8, so that the outer skin of the copper wire body 8 clamped between the two rubber plates 18 falls off. Then the material-guiding telescopic pneumatic cylinder 13 is controlled to work for the second time, and the material-guiding telescopic pneumatic cylinder 13 drives the double-axis pneumatic cylinder 15 to move to the position closest to the clamping structure inside the L-shaped plate 19. At this time, the double-axis pneumatic cylinder 15 and the two clamping frames 17 are in the loading position.

[0031] When the guiding telescopic pneumatic cylinder 13 completes its second operation, the pushing telescopic pneumatic cylinder 2 pushes the conductive terminal placed on the top of the pressure plate 20 into the L-shaped plate 19, and then the pushing telescopic pneumatic cylinder 2 is reset, and another conductive terminal is placed on the top of the pressure plate 20 {the automated loading of the conductive terminal is an existing mature technology, for example: placement by staff or placement by a robot, no specific restrictions are made here, and it is subject to processing needs}, and is sleeved onto the outside of the peeled part of the copper wire body 8, and then the riveting telescopic hydraulic cylinder 3 works to rivet the conductive terminal and the copper wire body 8 together.

[0032] After the riveting is completed, the staff controls the double-axis pneumatic cylinder 15 to work for the third time, the material-guiding telescopic pneumatic cylinder 13 to work for the third time, and the material-clamping telescopic pneumatic cylinder 11 stops working to drive the clamp 9 to reset, and the outer side of the copper wire body 8 loses its fixation. The double-axis pneumatic cylinder 15 that works for the third time drives the two clamping frames 17 to move toward the copper wire body 8 for a period of time and then stops working. At this time, the rubber plate 18 is slightly deformed and contacts the copper wire body 8. The blade 22 does not break the outer skin of the copper wire body 8. The two clamping frames 17 and the two rubber plates 18 cooperate to clamp the copper wire body 8. Subsequently, the material-guiding telescopic pneumatic cylinder 13 pushes the double-axis pneumatic cylinder 15 to move, and the clamped copper wire 8 is pulled, so that the conductive terminal connected to the copper wire 8 and a certain length of the copper wire 8 are pulled out of the L-shaped plate 19. When the material-guiding telescopic pneumatic cylinder 13 stops working, the material-clamping telescopic pneumatic cylinder 11 works again to clamp and fix the outer side of the copper wire 8, and the cutting structure works to cut off the copper wire 8. Subsequently, the double-axis pneumatic cylinder 15 works to drive the clamping frame 17 to reset, and the cut copper wire 8 falls, completing the riveting work of a section of the copper wire 8 and the conductive terminal, ensuring that the length of the cut copper wire 8 is roughly the same, and the quality of the riveting process of the copper wire 8 and the conductive terminal is ensured.

[0033] Then the material guiding telescopic pneumatic cylinder 13 drives the double-axis pneumatic cylinder 15 back to the inside of the L-shaped plate 19, and controls the double-axis pneumatic cylinder 15 to stay at the peeling position. Then the above process steps are repeated to automatically complete the peeling, quantitative cutting and riveting of the copper wire 8, avoiding the low product yield caused by manual peeling and positioning, and reducing labor cost investment.

[0034] The push-material telescopic pneumatic cylinder 2 is fixedly connected to one side of the inner part of the frame 1 to avoid the extra space occupied by the push-material telescopic pneumatic cylinder 2 , and the riveting telescopic hydraulic cylinder 3 is fixedly installed on the top of the frame 1 .

[0035] When the cutting structure is working, the cutting telescopic hydraulic cylinder 4 works. After the cutting telescopic hydraulic cylinder 4 fixedly installed on the frame 1 through the mounting frame 5 works and extends, the lifting frame 6 fixedly connected to the extended end of the cutting telescopic hydraulic cylinder 4 is pushed up. At this time, one side of the lifting frame 6 is fixedly connected to the drive motor 7 and the other side is rotatably connected to the tool 23 to move up. After the lifting frame 6 moves up a certain distance, the cutting telescopic hydraulic cylinder 4 drives the lifting frame 6, the drive motor 7 and the tool 23 to reset. During the working process of the cutting telescopic hydraulic cylinder 4, the drive motor 7 works. Since the tool 23 is fixedly connected to the output end of the drive motor 7, the tool 23 rotates to cut the copper wire 8 and cuts off the copper wire 8.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
