Publication number: 20190126416Abstract: A clamping device for an engine parts grinder, and its three-point clamping structure and pivoting control structure. With the three-point clamping structure and the pivoting control structure, the clamping device is capable of clamping the workpiece in a three point clamping manner with a stable clamping force. The pivoting control structure moves in pivoting motion to control the operating member to make the clamping member move downward or upward to clamp or to release the workpiece, and therefore the operation is very simple. Meanwhile, the operating member and the pressing unit provide a one-way self-locking function, and the elastic abutting unit presses against the cam portion of the pressing unit to create a position restricting effect. In addition to providing a stable clamping force, the operating member can be automatically locked when pivoted to a positioning position, which makes the clamping device very convenient to use.Type: ApplicationFiled: November 2, 2017Publication date: May 2, 2019Inventor: Feng-Yu Chang
