ELECTRIC CLAMP APPARATUS Russian patent published in 2016 - IPC B25B5/12 B25B5/16 

FIELD: electricity.

SUBSTANCE: invention relates to electric clamp apparatus. Electric clamp apparatus (10) for gripping blank with rotary clamping lever (20) includes body (12) and located inside body: drive unit (14) which is driven rotatably by electric signal; transmission mechanism (18) to transmit rotary drive force (14); worm gear to convert rotary motion transmitted by transmission mechanism (18) in to linear motion; toggle link mechanism (16) for converting linear motion transmitted by worm gear in to turning operation of clamping lever (20) clamping blank between lever (20) and support element (22) with clamping section (24); mechanism (52) of clamping lever (20), including pin (54) with distal end to clamp blank arranged to displace in hole (50) formed at the end of clamping lever (20), for use when gripping blanks of different thickness without need to adjust toggle link mechanism.

EFFECT: technical result consists in ensuring stable force for clamping blanks with different thickness without necessity of adjustment operations on clamping lever.
