Description

Linear cutting and chuck cutting tool for easily-deformed thin-wall sleeve

Technical Field

The utility model relates to a machining technical field, it is exact to say that it is a chuck frock is cut to wire-electrode cutting that is used for yielding thin wall cover to use.

Background

At present, the easily-deformed thin-wall sleeve cutting chuck is directly clamped at two points of the left end surface and the right end surface of the thin-wall sleeve for linear cutting, the bottom of the easily-deformed thin-wall sleeve is directly placed on a cross beam, and the excircle of the sleeve is supported by one line, so that the thin-wall sleeve cannot be uniformly stressed and cannot be uniformly supported. In the wire cutting process of the mode, the deformation amount is further increased by the easily-deformed thin-wall sleeve, and the thin-wall sleeve with an extremely thin wall and high precision is scrapped due to large deformation, so that the problem of low yield is particularly prominent. Therefore, the prior art can not meet the technical requirements of the thin-wall sleeve with extremely thin wall and high precision.

Disclosure of Invention

The utility model discloses a to the technological improvement that chuck frock was cut in the wire-electrode cutting of easy deformation thin wall cover, its purpose just provides a wire-electrode cutting who is used for easy deformation thin wall cover to cut chuck frock, does not increase the deflection of easy deformation thin wall cover, and the yield improves by a wide margin, application method is simple and convenient, can satisfy the removal chuck wire-electrode cutting frock of the thin wall cover that the wall is extra thin, the precision is high.

The utility model provides a chuck frock is cut in wire-electrode cutting that is used for yielding thin wall cover to use which characterized in that: the supporting body consists of a supporting seat and a supporting side plate, wherein the supporting side plate is provided with two fixing holes A for fixing the pressure plate 2, the pressure plate of the nested workpiece is locked and fixed by nuts B, the supporting seat is provided with bolt holes A and bolt sliding grooves, split V-shaped iron is fixed on the supporting seat by two sets of bolts A and nuts A, and the included angle is adjusted to be 60 degrees^oThe distance between the two split V-shaped irons ensures that the contact line of the workpiece and the split V-shaped irons is at the equal part of the circumference 3 of the workpiece.

The pressing body and the force-equalizing disc of the pressing disc transmit pressing force through three force-transmitting columns which are uniformly distributed on the circumference, and uniform stress of the easily-deformed thin-wall sleeve is ensured.

When the diameter size of the workpiece is 330mm, 300 mm and 270 mm, the distances 9 between the bottoms of the split V-shaped irons are respectively adjusted to be 190 mm, 173mm and 155mm, and the supporting points are ensured to be on three equal parts of the circumference of the workpiece.

The utility model has the advantages that: it can not guarantee that thin wall cover atress is even when having overcome yielding thin wall cover line among the prior art and cutting off the chuck, causes yielding thin wall cover further to produce the problem of warping, the utility model discloses the clamping is stable, the atress is even, reduce the deformation of wire-electrode cutting process, and the clamp is cut to wire-electrode cutting's effectual, especially adapted wall is extra thin, the yielding thin wall cover class work piece that the precision requirement is high.

Detailed Description

Example (b):

the embodiment of the utility model provides a diameter 330 millimeters, the yielding thin wall cover of wall thickness only 4.5 millimeters, the implementation adopts low carbon steel sheet material processing supporter 1, guarantees the flatness of 11 upper surfaces of supporting seat with the perpendicular and two surfaces of support curb plate 12 working face, opens two fixed orificess A14, a fabrication hole 16 and two hole for hoist 18 on supporting curb plate 12 according to the drawing, opens two bolt holes A13 on supporting seat 11, processing bolt sliding tray 15 and two fixed orificess B17. The support body 1 is fixed on a wire cutting machine through two bolts B7 and the included angle 60 is adjusted^oThe distance between the two split V-shaped irons 4 is 190 mm, so that the contact line of the workpiece 8 and the split V-shaped iron 4 is at the position of the circumference 3 of the workpiece which is equally divided, firstly, the nut of the bolt A5 is slid into the bolt sliding groove 15 of the supporting seat 11, the screw rod penetrates into the bolt hole B41 of the split V-shaped iron 4, and the nut A6 is used for locking. The pressing disc body 21, the force transmission column 22 and the force equalizing disc 23 are welded together and then machined, the two connecting studs 25 are welded on the cross rod 24 and then are spot-welded on the force equalizing disc 23, the end of a workpiece chuck is placed in the pressing disc body 21, the two connecting studs 25 are inserted into the fixing holes 14 in the supporting side plates 12 and are locked by nuts B3, and the rotor core is ensured to be uniformly fixed on a fixture under stress.

The utility model is suitable for a chuck wire-electrode cutting is removed to various yielding thin wall covers such as rotor core, and the concrete size of pressure disk part 2 can be decided according to the concrete size of thin wall cover.
