The magnetic type electric spark machining fixture capable of being matched with parts with different appearances provided by the second embodiment only realizes the automatic clamping process of machining all surfaces in electric spark machining, but in the actual machining process, only any surfaces need to be machined at times, and the surfaces have no fixed angle relation, at the moment, if the clamping of one surface is carried out on one surface, the work efficiency is slow, the workpiece can be damaged by multiple times of clamping, and in order to avoid the situation that the workpiece is clamped for multiple times, the magnetic type electric spark machining fixture can be matched with a machine tool terminal control system and the fixture to carry out the following operations:
after one processing surface of a workpiece is processed, a specific other surface to be processed needs to be processed, an X surface and a Y surface are preferentially determined similarly to the second embodiment, the Z surface is a moving surface in the vertical direction of the workpiece, the electric telescopic rod 13 can be driven by the waterproof motor 5 to realize displacement on the Z surface, the first embodiment can know that an included angle between the spatial position of the surface to be processed and the processed surface can be detected by a laser distance meter on the outer surface of the elastic clamping plate 7, the required rotation angle of the workpiece can be calculated by a machine tool terminal, and then the workpiece is decomposed on the X axis, the Y axis and the Z axis, so that the workpiece is controlled to rotate along the X axis, the Y axis and the Z axis to reach a processing surface, the specific operation can be combined with the second embodiment, two electric telescopic rods 13 on the Y surface are electrically controlled to shrink firstly, the magnetic fixing block 12 on the surface is not contacted with the workpiece, and at the moment, the electric telescopic rod 13 on the X surface is controlled to rotate along the X axis by a certain angle, and controls the waterproof motor 5 to control the electric telescopic rod 13 to lift in the vertical direction, thereby determining that the proper height is reached, then electrically controls the Y-surface electric telescopic rod 13 to extend, so that the magnetic fixed block 12 is contacted with and clamped by the workpiece, then the X-surface electric telescopic rod 13 contracts for a certain distance, so that the X-surface magnetic fixed block 12 is not contacted with the workpiece, at the moment, the operations are repeated, so that the workpiece rotates for a certain angle along the Y axis, and controls the electric telescopic rod 13 on the X surface to lift to a certain height, then controls the electric telescopic rod 13 on the X surface to clamp the workpiece, then repeats the positioning and clamping operation of the first embodiment to the workpiece to enable the clamp to clamp the workpiece, when multiple surfaces of a workpiece need to be machined, the optimal rotation mode is selected by the machine tool terminal only after the angle is measured initially, and then the operation is carried out according to the optimal rotation mode, and repeated operation is not repeated.
The invention solves the problem that the surface to be processed of the workpiece is changed in space in the actual processing process by arranging two groups of electric telescopic rods 13, elastic clamping plates 7 and magnetic fixing blocks 12 which are symmetrically distributed, when the surface to be processed of the workpiece is changed into any one surface of the workpiece, the space needs to be controlled to rotate for a proper angle along one shaft, then the workpiece rotates for a certain angle along the other shaft, and finally the laser range finder judges whether the workpiece reaches a proper position. The automatic clamping device is convenient and quick to operate, can realize one-time clamping to process the characteristic surface of a workpiece instead of processing, completely releases manpower, is completely completed by mechanical operation, and is combined with a previous positioning and clamping mode, so that the clamping precision is higher, and the operation is simpler and more convenient.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
