Abstract
A center vise structure includes a base with two sides, two side slots and/or two embedding slots. Multiple zero point positioning pins are connected to a bottom of the base. A vise is placed on the base. A transmission shaft includes two external threaded parts having different thread directions, which are respectively connected with two internal threaded parts of the vise. A supporting seat is located inside the base and is used to support and position the transmission shaft. Before a mechanical arm grips the vise and installs it into a machine tool, by rotating one end of the transmission shaft, the vise grips the workpiece and automatically aligns with its machining reference center point position.

A center vise structure, comprising:
- a base (1) having a receiving slot (11) that communicates with a top surface (12) and two end faces (13) of the base (1), a zero point slot (14) located at a middle of a bottom of the receiving slot (11), several zero point positioning pins (16) provided on a bottom of the base (1), the zero point positioning pins (16) adapted to be fit into a processing table of a machine tool;
- a vise (2) having a first movable jaw block (21) and a second movable jaw block (22) that are opposite to each other and symmetrical to the zero point slot (14), the first movable jaw block (21) having a first embedding part (211) connected to an underside thereof, a second embedding part (221) connected to an underside of the second movable jaw block (22), the first and second embedding parts (211, 221) located in the receiving slot (11) of the base (1), the first embedding part (211) and the second embedding part (221) respectively having a first internal threaded part (212) and a second internal threaded part (222), spiral directions of internal threads of the first internal threaded part (212) and the second internal threaded part (222) being different;
- a transmission shaft (3) having a first external threaded part (31) and a second external threaded part (32) respectively located on two sides of a middle pivot connection (30), the first external threaded part (31) and the second external threaded part (32) respectively connected with the first internal threaded part (212) and the second internal threaded part (222) of the first embedding part (211) and the second embedding part (221) of the vise (2), two ends of the transmission shaft (3) being connecting ends (33), and
- a supporting seat (4) having a lower part thereof connected to the zero point slot (14), an upper part of the supporting seat (4) connected to the middle pivot connection (30) of the transmission shaft (3) to support and position the transmission shaft (3), by using a hand tool (7) to connect to one of the connecting ends (33) of the transmission shaft (3), and rotating the transmission shaft (3), the vise (2) grips or releases a workpiece (5).
