[0014] The present invention provides an ultrasonic welding machine for precision mechanical engineering that prevents splashing. It has the following beneficial effects:

[0015] (1) The ultrasonic welding machine for preventing splashing for precision mechanical engineering uses a U-shaped frame to move and reset to contact the inner wall of the shielding hole and limit the splash plate. By limiting the splash plate by the U-shaped frame, it can ensure that the splash plate is always in a shielding state during the welding process, thereby effectively blocking welding spatter, sparks and other high-temperature substances, and effectively preventing the protective cover from accidentally opening during operation. When the ultrasonic welding equipment is used for welding, the splash plate is limited by the U-shaped frame and cooperates with the baffle to shield the waste slag generated by the welding. The splashing waste slag will cause damage to the equipment. By setting the splash plate and the baffle, the waste slag can be prevented from contacting sensitive parts, thereby extending the service life of the equipment and ensuring the safety of workers.

[0016] (2) The ultrasonic welding machine for preventing splashing for precision mechanical engineering drives the arc plate to move by moving the T-shaped plate in a direction away from the U-shaped frame. The arc plate moves to squeeze and align the workpiece inside the processing groove. By squeezing and aligning the workpiece by the movement of the arc plate, the position of the workpiece during the welding process can be ensured to be stable, thereby avoiding poor welding caused by inaccurate position of the workpiece. The side of the workpiece is squeezed by the pressing plate in conjunction with the pressing spring to ensure the close fit of the welding place of the two workpieces. The cooperation of the pressing plate and the pressing spring can effectively make the two workpieces close together during the welding process, thereby preventing welding failure or uneven welds caused by poor contact.

[0017] (3) The ultrasonic welding machine for preventing splashing for precision mechanical engineering drives the protective rod to move by moving the protective plate toward the button. The protective rod moves out of contact with the protective groove and releases the limit on the button. The button can be pressed only after the limit on the button is released. The button is pressed to drive the ultrasonic welding equipment to perform welding. If the position of the workpiece is not accurate, it will cause uneven vibration and affect the welding effect. The ultrasonic welding equipment can be started by pressing the button only after the accurate position of the workpiece is detected, which can ensure the precise docking of the welding surfaces and improve the welding quality.
