An Efficient and Fast Electrode Replacement Clamping Fixture

Abstract

The invention discloses an efficient and fast electrode replacing clamping fixture. The efficient and fast electrode replacing clamping fixture comprises a supporting seat. A top column is mounted atthe top end of the supporting seat. A fixed ring is mounted in the center of the top end of the top column. A center round hole is formed in the top end of the fixed ring. A plurality of clamping grooves are formed in the outer side of the circumference of the surface of the top end of the top column. Second grooves are formed in the left side and the right side of the bottom end of each clampinggroove. A second clamping plate is mounted on the inner side of each second groove. According to the efficient and fast electrode replacing clamping fixture, when an electrode is replaced, by placingthe inner sides of the clamping grooves into an electrode column, and a pushing rod is pressed to move by pressing the electrode; when the electrode column needs to be taken out, the pushing rod is pressed to move by pressing the electrode, a pressing plate is pressed to move through the pushing rod, and a pulling rod is driven to divorced from the inner side of a clamp groove, so that the secondclamping plates are divorced, the pushing rod can move upwards, the electrode column is pushed out of the inner sides of the clamping grooves, and thus performance operation is simple, the convenientand fast effects are achieved, and effective promotion is brought for replacement of the electrode.

Description

technical field [0001] The invention relates to the technical field of electrode clamping jigs, in particular to an efficient and fast electrode replacement clamping jig. Background technique [0002] When EDM machine tools are used to process and manufacture electrodes, due to the complex shape of the machine tool and the small size of the electrodes, there are usually problems in the manufacture of electrodes that cannot process reference planes and electrodes used in tool magazines. The existing electrode clamping Fixtures can improve the above problems to a certain extent, but there are still problems such as inaccurate positioning reference, poor positioning accuracy, long electrode replacement and adjustment time, and low efficiency. For example, the patent with application number 201420562666. Chuck, locking device, clamping rivet, auxiliary locator and chuck, the positioning plate and the chuck are respectively installed on both sides of the base, the locking device ...

Problems solved by technology

[0002] When EDM machine tools are used to process and manufacture electrodes, due to the complex shape of the machine tool and the small size of the electrodes, there are usually problems in the manufacture of electrodes that cannot process reference planes and electrodes used in tool magazines. The existing electrode clamping Fixtures can improve the above problems to a certain extent, but there are still problems such as inaccurate positioning reference, poor positioning accuracy, long electrode replacement and adjustment time, and low efficiency. For example, the patent with application number 201420562666. Chuck, locking device, clamping rivet, auxiliary locator and chuck, the positioning plate and the chuck are respectively installed on both sides of the base, the locking device is installed on the opposite side of the chuck and the base, and the auxiliary The positioner is installed on the other side of the positioning plate opposite to the base. The base is provided with a first threaded central hole and four cross-distributed opening structures. The positioning plate is provided with a hollow round hole and four cross-distributed squares. hole, the chuck is fixedly connected with the opening structure and square hole, although the human error is greatly reduced, but it is troublesome to install and take the electrode column, which is very inconvenient and brings more workload to replace the electrode
