Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing positioning, in particular to an electric pulse processing tool. Background Art

[0002] A machining tool is a device used to fix the parts to be machined during product machining, so as to facilitate accurate machining and reduce machining errors. During the pulse machining process, the mold parts to be machined need to be placed in the pulse machine tool and then the parts to be machined need to be straightened using a dial indicator. Then, the electrodes are used to find the center coordinates of the parts to be machined in the four-sided reference points of the parts to be machined. Each time an electrode is replaced, it needs to be re-centered to find the machining reference starting point. However, in the prior art, due to its complex operation, low efficiency, and failure to meet the mold precision requirements, it has poor practicality. Therefore, the present application discloses an electric pulse machining tool to improve the machining accuracy of high-precision parts and improve practicality. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide an electric pulse machining tool to solve the problem of ensuring accuracy when manufacturing high-precision parts.

[0004] Based on the above purpose, the utility model provides an electric pulse machining tool, including a fixed ring, a plurality of through circular grooves are provided on the fixed ring, and a plurality of fixed frames are installed on the inner wall of the fixed ring, a positioning block is installed below the fixed frame, a guide ring is installed at the center position of the fixed ring, a vertical guide rod is inserted into the circular groove, a limiting block is installed at one end of the vertical guide rod, and the other end of the vertical guide rod is fixedly installed on the positioning ring, and a vertical spring is sleeved on the vertical guide rod, and the two ends of the vertical spring respectively abut against the side surfaces of the fixed ring and the positioning ring.

[0005] Preferably, an electrode seat is provided on the guide ring, the diameter of the electrode seat is the same as the diameter of the guide ring, and an electrode is installed at the bottom end of the electrode seat.

[0006] Preferably, the inner wall of the positioning ring is provided with a matching mold positioning tooth, a connecting block is installed on the inner side of the mold positioning tooth, and the mold positioning tooth is installed on the part cylinder through the connecting block. The inner diameter of the part cylinder is the same as the inner diameter of the guide ring and the diameter of the electrode seat.

[0007] Preferably, a mold positioning block is installed on the other side of the part cylinder, and the shape of the mold positioning block is fan-shaped.

[0008] Preferably, a positioning block is installed at the bottom end of the fixing frame, and the inner wall size of the positioning block is the same as the outer wall size of the mold positioning block.

[0009] Preferably, the part cylinder can be embedded inside through the mold positioning teeth and the mold positioning block in cooperation with the positioning ring and the positioning block.

[0010] Preferably, the inner wall of the positioning ring is provided with serrations which match the positioning teeth of the mold.

[0011] The beneficial effects of the utility model are as follows: when the machine is in use, the positioning ring and the positioning block move in the direction of the vertical guide rod under the push of the fixed ring. At this time, the positioning block and the positioning ring cooperate with the mold positioning teeth and the mold positioning block to keep the angle and direction of the electrode and slowly push it into the part cylinder. Moreover, because of the action of the vertical spring, when the electrode holder pushes the electrode, it will not suddenly fall and cause damage to the parts. After a work is completed, the electrode holder will drive the electrode to be slowly pushed out through the guide ring. Moreover, because of the limiting block, the fixed ring will not fall off from the vertical guide rod after the work is completed, until it is completely in a natural state, completing a precise work.
