Quick and batch clamping jig for linear cutting machining

Abstract

The invention discloses a quick and batch clamping jig for linear cutting machining. The quick and batch clamping jig comprises a jig body and auxiliary parts. The jig body is provided with a centering zero position hole and four square holes, and the geometric centers of the four square holes coincide with the center of the centering zero position hole. Threaded through holes communicating with the square holes in a one-to-one correspondence manner are formed in the side wall of the jig body, and grub screws are connected into the threaded through holes in a threaded manner. Two threaded blind holes and a plurality of V-shaped grooves used for containing cylindrical inserts are symmetrically formed in a set of opposite side walls of the jig body, and the cylindrical inserts placed in the V-shaped grooves are tightly abutted through the auxiliary parts. The quick and batch clamping jig has the beneficial effects that the jig not only can clamp and fix the inserts, but also can correct the reference surface and conduct centering, so that the correcting and centering time before linear cutting is greatly shortened. The correcting and centering effects are good, and the machining precision of the mold inserts is guaranteed. The plurality of mold inserts can be machined at a time, so that the machining efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of wire-cut processing mold inserts, in particular to a fast and batch clamping jig for wire-cut processing. Background technique [0002] Wire cutting is a very important process in the processing of mold inserts. When processing inserts by wire cutting, it is necessary to divide the inserts first. The centering of wire cutting refers to finding the center point of the part. Take a square part as an example. When centering, adjust the spark, let the spark touch one side, and reset the scale of the hand wheel to zero, then let the spark touch the opposite side, and see the number of scales. , the number of scales divided by two is the center position of the two opposite sides, and the other two opposite sides are also operated in the same way. [0003] At present, when wire cutting inserts are processed, the inserts are directly fixed on the working platform, and the working platform is used as the referenc...

Problems solved by technology

This processing method can only fix one entry at a time, and there is no zero reference position when the entry is divided into numbers. Every time an entry is processed, it must be divided and counted several times. The process is cumbersome and very time-consuming (one It takes about 15 minutes for the average time to correct the centering of the inserts), and there is no guarantee that there will be no centering errors when each insert is cut online. If there is an error, the processed inserts will be scrapped
