Description

TECHNICAL FIELD

[0001] The present application relates to the field of ultrasonic welding equipment, in particular to an ultrasonic welding machine and a fine adjustment stroke assembly and a use method thereof. BACKGROUND

[0002] The ultrasonic welding machine is an advanced high-tech equipment that converts high-frequency electric energy into mechanical vibration energy through a transducer and acts on workpieces to generate high-frequency friction between the surfaces of the workpieces until the surfaces are melted and welded together. The ultrasonic welding machine has the advantages of high work efficiency, simple operation and labor cost saving, and is widely used in the daily necessities industry, toy industry, electrical industry, automobile manufacturing industry and electronic industry.

[0003] The fine adjustment stroke assembly of the existing ultrasonic welding machine is arranged in a fixed seat and is threadedly connected with the fixed seat. The fine adjustment stroke assembly mostly adopts a fine adjustment pointer and a scale groove on a machine head panel to cooperate, so as to facilitate observation and adjustment of the descending stroke of the vibration cylinder assembly. The fine adjustment stroke assembly of the ultrasonic welding machine is fixed by a limiting bolt arranged on the side wall of the fixed seat to prevent the fine adjustment stroke assembly from rotating in the process of working of the ultrasonic welding machine, so that the set stroke changes and causes welding deviation and reduces welding quality. However, the scheme has many parts and is complex to install. The machine head panel is provided with a groove. When the limiting bolt needs to be tightened, the machine head shell blocks the side wall of the fixed seat, and the locking effect is limited. The hand of the user needs to be inserted into the machine head shell to rotate the limiting bolt, and there is a risk of rotation out of position. SUMMARY

[0005] The second object of the present application is to provide an ultrasonic welding machine comprising the fine adjustment stroke assembly.

[0006] The third object of the present application is to provide a use method applied to the fine adjustment stroke assembly.

The fine adjustment knob is fixedly connected with the fine adjustment screw rod. The locking part is threadedly connected with the fine adjustment screw rod and can move along the axial direction of the fine adjustment screw rod.

[0008] From the above, through the locking component arranged on the fine adjustment screw rod together with the fine adjustment knob, the locking component is rotated to lock the fine adjustment screw rod, the structure is simple, convenient to disassemble and lock, and the locking effect can be further improved.

[0017] From the above, the counterbore hole arranged on the surface of the end wall of the locking knob close to the fixed seat can avoid the problem that the locking knob cannot abut to the bottom surface of the fixed seat due to the machining tolerance of the fine adjustment mounting seat, preventing the problem of unable to lock and the problem of certain precision deviation.

[0018] Further, the outer surface of the fine adjustment knob close to the fixed seat is provided with a second scale line arranged in the circumferential direction of the fine adjustment knob.
