Problems solved by technology

[0009] The above is the necessary process for processing a single workpiece, which takes about 20 minutes, so the efficiency of correcting the workpiece and aligning the workpiece coordinates before EDM is very low
If multiple workpieces of the same type are processed together, it will waste more time and the efficiency will be lower

Abstract

A discharging correction edge-finding tool is installed on a discharging machine and comprises a fixed end which has one end connected with the main shaft of the discharging machine, and is provided with a groove; and a working end composed of two working faces perpendicular to each other, and having one end fixed in the groove and the other end in contact with a workpiece. In workpiece correction, the right-angle side of the workpiece is abutted against the working face of the working end, the workpiece and the main shaft form a positive electrode and a negative electrode respectively, the buzzer of the discharging machine sounds, the workpiece is then fixed and the workpiece coordinates are set. The inventive discharging correction edge-finding tool is simple and convenient to operate, and can simplify workpiece correction edge-finding, originally accomplished by a plurality of steps and a plurality of tools, to be accomplished by one step and one tool, to shorten time from original 20min to 2min and improve correction and coordinate finding efficiency.

Description

【Technical field】 [0001] The invention relates to a jig, in particular to a discharge correction centering jig applied to a mold. 【Background technique】 [0002] Before electric discharge machining, the correction of the workpiece and the determination of the coordinate position are particularly important for the efficiency and quality of the workpiece processing. The usual steps are: [0003] 1. Place the workpiece on the magnetic table; [0004] 2. Install the dial indicator; [0005] 3. Use the dial gauge and copper rod to assist in the horizontal correction of the workpiece in the X and Y directions; [0006] 4. Apply magnetism to the magnetic table to absorb and fix the workpiece, and install the centering reference rod; [0007] 5. Use the centering reference rod to find the center of the workpiece in the X and Y directions; [0008] 6. Set the workpiece center coordinates. [0009] The above is the necessary process for processing a single workpiece, which takes...
