Machining reference structure of work piece on non-standard wedge of die

A machining reference structure of a work piece on a non-standard wedge of a die comprises a lower die base, a wedge sliding block, an upper die base and a reference block. The lower die base is provided with a wedge sliding block driving block, and the upper surface of the wedge sliding block driving block is provided with a guide slope gradually declining towards the front side. The front end of the wedge sliding block is used for installing the work piece to be machined, the wedge sliding block is located on the guide slope, the upper surface of the wedge sliding block is provided with a spring, the rear end of the spring is fixed to the wedge sliding block, and the front side of the wedge sliding block is provided with a reference surface. The upper die base is provided with a compression surface capable of compressing the spring from the front end of the spring, and a reference block installation surface corresponding to the reference surface. The reference block is fixed to the reference block installation surface. The machining reference structure is simple and convenient to install and use, prevents the non-standard wedge from shaking in the machining process, enables the non-standard wedge to be stable in the machining process and then achieves high accuracy of machining of the work piece.
