Technical Field

The utility model belongs to the technical field of spare part, specific electrode 3R anchor clamps extracting tool in electric spark equipment that says so.

Background

After the electrode pair is processed on a workpiece, the 3R clamp needs to be disassembled and installed on other electrodes for processing. The connecting and positioning of the clamp and the electrode are fixed by two positioning pins with the diameter of 6mm, the precision is 0.002mm, the gap is very small, the connection is very tight, and the clamp cannot be taken down from the electrode without a tool.

Usually, an operator clamps and fixes the electrode by using a bench vice, aligns a tool such as a screwdriver or a flat shovel at a quasi-joint of the clamp and the electrode, strikes the electrode by using a hammer, and pries the clamp down after loosening.

The 3R clamp belongs to a precision clamp, the positioning precision is 0.002mm, the price is high, the precision of the clamp is reduced by using the knocking method, the clamp is mounted on an electrode again for use, the quality risk is very high, the detached electrode cannot be reused due to the looseness of the positioning pin, the waste is great, and the manufacturing cost of a die is increased.

Disclosure of Invention

The utility model discloses dismantle and develop to electrode holder among the electric spark equipment, the utility model provides a simple structure's electrode 3R anchor clamps extracting tool in the electric spark equipment, it can be quick to utilize this kind of instrument, the 3R anchor clamps of harmless dismantlement, guarantee the anchor clamps precision, the effectual precision that has avoided knocking to bring for the electrode after anchor clamps and the shaping of this instrument descends, the electrode repeatedly usable who utilizes this instrument to dismantle, reduce the mould cost, improve mould market competition, the current accurate junction of aiming at anchor clamps and electrode with the instrument of screwdriver or flat shovel class has been solved, strike with the hammer, it gets off the not hard up that there is the locating pin to shake not hard up the back with the anchor clamps sled, also can't reuse, cause very big waste, the problem of the manufacturing cost of mould has been increased.

The technical scheme of the utility model is explained as follows with the attached drawings:

an electrode 3R clamp dismounting tool in electric spark equipment comprises a screw rod wrench 1 and a jaw main body 2; the screw rod wrench 1 is in threaded connection with the jaw main body 2; the bottom of the jaw body 1 is uniformly distributed with jaws 3, and the jaws 3 are fixed with a 3R clamp.

The lower end of the screw rod wrench 1 is provided with an external thread with the diameter of 10 mm.

The jaw body 1 is a cylinder.

The middle of the jaw body 1 is provided with an internal thread matched with the external thread.

The claw 3 is of a reverse L shape.

The number of the clamping jaws 3 is four, and the clamping jaws are clamped on four bosses 4 at the middle hole of the 3R clamp respectively.

The utility model has the advantages that:

1) the utility model has simple structure, and can reduce the cost;

2) the utility model can rapidly and nondestructively disassemble the 3R clamp, thereby ensuring the precision of the clamp, and effectively avoiding the reduction of precision brought by knocking the clamp and the formed electrode;

3) utilize the utility model discloses the electrode repeatedly usable who dismantles reduces the mould cost, improves mould market competition.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 5, an electrode 3R jig removing tool in an electric discharge apparatus includes a screw wrench 1 and a jaw body 2.

The jaw body 1 is a hollow cylinder, and the middle of the jaw body is provided with an internal thread.

Four clamping jaws 3 are uniformly distributed at the bottom of the clamping jaw main body 1.

The jack catch 3 is the reverse L shape, in order to be the same with lead screw spanner screw-in direction, avoids hook and 3R anchor clamps boss 4 to break away from. When in use, the four bosses 4 at the middle hole of the 3R clamp are hooked.

The lower end of the screw rod wrench 1 is provided with an external thread with the diameter of 10mm, the external thread is in threaded connection with the internal thread of the jaw body 1, and the rotary motion of the screw rod wrench 1 is converted into the axial motion to realize the ejection action.
