Description

Technical Field

[0001] This utility model relates to the field of crystal oscillator lead trimming machine technology, and more specifically, it relates to a crystal oscillator lead trimming machine. Background Technology

[0002] A crystal oscillator lead trimming machine is a specialized device used for automatically or semi-automatically cutting off excess length from the leads of a quartz crystal resonator (crystal oscillator). It is widely used in the pre-processing steps of electronic component manufacturing and PCB assembly. Its core objective is to precisely, efficiently, and non-destructively trim the crystal oscillator leads to a uniform standard length, avoiding problems such as lead misalignment, housing breakage, and inconsistent lengths caused by manual lead trimming.

[0003] Existing crystal oscillator lead cutting machines are not convenient to adjust to the required cutting length for different cylindrical crystal oscillator leads, which limits their use. Moreover, when the blade cuts the crystal oscillator, the downward force of the blade can easily cause the crystal oscillator to move downward, thereby damaging the crystal oscillator.

The support frame is slid to a suitable position according to the length of the crystal oscillator, and the two sets of T-blocks slide in the two sets of T-slots of the operating table. Then, the two sets of bolts are rotated, and the two sets of bolts are threadedly connected to the two sets of mounting plates, thereby fixing the support frame and facilitating the adjustment of the position of the support frame according to the length of the crystal oscillator.
