[ detailed description ] embodiments

The invention will be described in detail below with reference to the drawings, wherein examples of the embodiments are shown in the drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1 of the drawings, there is shown an interchangeable machining jig comprising a base 10 and two or more replacement plates 20 on which products to be machined are positioned and clamped, the base 10 being adapted to be clamped on a machining machine, and if it is desired to place the products one by one on the jig in the machine, there is a significant time delay so that a replacement plate on which loading has been completed is directly mounted on the base and the base is fed into the machine for machining, and in the course of machining a first replacement plate, the time is used to unload and load a second replacement plate, and after the first replacement plate is removed, the loaded second replacement plate is directly fed onto the base, so that the machining process can be completed in a very short time, and the machining process can be repeated for the previous cycle. Therefore, the standby time is short, and the efficiency is high.

The base 10 comprises a fixing plate 11, a pneumatic fixing piece 12 and a positioning plate 15, the positioning plate 15 is arranged on the fixing plate 11 of the base 10, the pneumatic fixing piece 12 is arranged on the side face of the positioning plate 15, and when the replacement plate 20 is positioned and placed on the positioning plate 11, the pneumatic fixing piece 12 is started and presses the replacement plate.
