The third cylinder 51 can drive the driving rod 52 to move along the extension direction of the lower slide 421 to drive the steel ball to move from the second pre-riveting position to the steel ball hole of the shell 9 for pressure riveting. The four riveting parts 5 correspond to the four lower slides 421 of the two steel ball moving parts 4, respectively, so as to realize the simultaneous riveting of the four steel ball holes of the shell 9.

[0045] Preferably, Figure 1 and Figure 2 As shown, in an embodiment, the steel ball riveting device may further include: an electric control cabinet 7 and a safety grating 8. The electric control cabinet 7 may be fixed to the first end of the upper part of the substrate 1 (which may be the end of the substrate 1 where the fourth cylinder 23 is installed) by bolts, and the electric control cabinet 7 may be connected to the housing moving part 2, the incoming bin 3, the steel ball moving part 4, the riveting part 5 and the housing pressing part 6 by wires, and the electric control cabinet 7 is used to control the start and stop of the steel ball riveting device. A safety grating 8 may also be installed at the second end of the upper part of the substrate 1 (which may be the opposite end of the first end). The safety grating 8 is installed in groups on both sides of the second end of the substrate 1 and fixed to the upper part of the substrate 1 by a bracket 80. The bottom end of the bracket 80 may be bolted to the top of the substrate 1, and the safety grating 8 may be fixed to the middle part of the bracket 80 by bolts. When the safety grating 8 detects a staff member, the steel ball riveting device will not start to avoid injury to the staff member.

[0046] During use, the staff can first install the shell 9 on the slider 22, and then press the start button of the electric control cabinet 7 with both hands. The shell moving part 2 moves the shell 9 to the first pre-riveting position 91, and the shell pressing part 6 presses the shell 9. The brush body 32 in the incoming bin 3 rotates and drives the steel balls, so that the steel balls continuously flow into the discharge channel 330, and move through the first through hole 410 of the upper plate 41 to the lower slide 421 of the lower plate 42. In the meantime, the photoelectric sensor 45 detects the falling of the steel balls in the first through hole 410 to avoid missing rivets. After the second cylinder 44 drives the lower plate 42 to move the steel balls to the second pre-riveting position, the driving rod 52 of the riveting and pressing part 5 drives the steel balls to move to the steel ball holes of the shell 9 for riveting. The four riveting and pressing parts 5 work simultaneously so that the shell 9 can complete the riveting of four steel ball holes at one time. Finally, the shell moving part 2 moves the shell 9 with the steel ball riveted from the first pre-riveting position 91 to facilitate the staff to replace the shell 9. In this way, the efficiency of the steel ball riveting of the shell 9 is improved, and the steel ball riveting device is driven by a cylinder, which can further reduce the cost.
