[0029] The applicant has made improvements to the ultra-quiet, energy-saving small press disclosed in the earlier patent application with publication number CN202826447U.

[0030] like Figures 1 to 7 As shown, this application provides a high-stability, ultra-quiet riveting machine, including a mold frame 1, a motor assembly 2, a transmission sleeve 3, and a slider assembly 4. The motor assembly 2 includes a motor 20, a gearbox 21, and an eccentric shaft 22. The motor assembly 2 also includes a frequency converter, which is electrically connected to the motor. Based on variable frequency speed control technology, the system can achieve high-precision electronic positioning. By adjusting the motor's operating frequency in real time, the motor can be kept in a zero-speed standby mode when not in operation, significantly reducing system energy consumption.
