Description

Multi-point clamping device

This creation is about a tool holding device, especially a multi-point clamping device.

The common basic structure of the vise is mainly provided with a fixed cymbal at one end, and a movable cymbal that is driven by the screw to slide on the top surface of the vise, thereby holding the workpiece fixed by the fixed cymbal and the movable cymbal, However, such a vise structure can only clamp a workpiece at a time and perform a single workpiece processing, so that the processing personnel must frequently loosen and replace the workpiece on the vise during a large number of processing operations. Caused troubles and inconveniences in processing operations.

In addition, a conventional fixture structure, such as the fixture structure of the two-way cooperating clamping positioning, which is approved by the Department of Economics on August 21, 1987, is mainly included in the following: The two abutting blocks are respectively formed with a tapered tapered surface on opposite sides of the two abutting blocks, and a pushing block having the same taper as the tapered mask is disposed between the tapered faces of the two abutting blocks. The upper part is provided with a bolt penetrating through the pushing block, and the two side surfaces of the abutting block providing spring are respectively provided with a spring bucking block for the spring to be hooked, and the side of the abutting block provided with the spring is provided with one side plate, respectively The side plate is convexly formed with a restriction strip that can abut against the spring.
