US Patent 11766762 Adjustable vise system

A workholding system includes an adjustable vise, a fixed vise, and a fixture plate. The adjustable vise and the fixed vise are secured to the fixture plate using a T-slot and a fastener. The system includes multiple precision locating surfaces, including interchangeable precision locating surfaces, to secure a working part. In one embodiment, a T-slot fastener facilitates the creation of an entire workholding system that facilitates the rapid installation of studs into receiving members. The fastener includes a quarter turn fastener used in workholding applications to quickly hold and release components of the system, such as tooling, parts, and plates. The compact design of the system makes possible the ability to insert the quarter turn fastener into a device that can fit into a T-slot and still have considerable holding power. The system is lower in cost than other solutions.
