Technical Field

The utility model belongs to the machining field, in particular to replace wire-electrode cutting processing frock of dividing head among wire-electrode cutting processing.

Background

The roundness error, the straight line error and the size error of the slow wire cutting machine are much better than those of the fast wire cutting machine, so that the slow wire cutting machine is widely applied to production when high-precision parts are machined. When the flexible material part is processed by wire cutting, various flexible wall grooves can be processed only by using a dividing head, and the following problems need to be solved by using the dividing head: (1) the precision of the dividing head can not be achieved; (2) and the clamping and the alignment are carried out for multiple times, so that the preparation time is far longer than the processing time.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the dividing head precision and can not reach and processing at every turn and need adorn card and alignment time overlength to the dividing head, provided a wire cut electrical discharge machining frock. In order to achieve the above purpose, the utility model adopts the following specific technical scheme:

the utility model provides a wire cut electrical discharge machining frock, includes: the square groove is machined in the center of the horizontal plane on one side of the regular 2n prism; the included angle theta between any one symmetry axis of the square groove and any one symmetry axis of the horizontal plane of the regular 2n prism body satisfies the following formula:

θ＝180°/2n

wherein θ is an integer;

n represents the number of the thin walls of the piece to be cut, and n is more than or equal to 8.

Preferably, the method further comprises machining a through hole for weight reduction at a central position, the diameter of the through hole being smaller than the diameter of the piece to be cut.

Preferably, the depth of the square groove is matched with the thickness of the fixed platform of the piece to be cut, so that the square groove is abutted to the lower surface of the fixed platform of the piece to be cut, and the upper surface of the fixed platform of the piece to be cut and the upper surface of the regular 2n prism are on the same horizontal plane.

Preferably, threaded holes are symmetrically machined in the surface, abutted to the fixing platform of the piece to be cut, of the square groove for fixing the piece to be cut.

The utility model discloses can gain following technological effect:

1. and the processing precision is improved.

2. The time for installing and aligning the card is shortened, the processing efficiency is improved, and the processing cost is saved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not constitute limitations on the invention.

The utility model aims at providing a when adopting the wire-electrode cutting processing mode to the work piece that needs the cutting to have a plurality of flexible thin walls, replace the dividing head and carry out dress card and frock of alignment. The following will explain the present invention in detail by means of specific embodiments.

As shown in fig. 3, the fixed platform of the workpiece to be cut is a square platform with the thickness of 3mm and the diameter of 24mm, the outer diameter of the workpiece is 20mm, as shown in fig. 4, the excircle of the right end phi 20 of the workpiece to be cut is taken as a reference A, and the coaxiality of the excircle of the left end phi 20, the phi 4.5 hole and the phi 8 inner hole of the right end phi 8 with the reference A is required to be phi 0.008 mm; the axial of a workpiece to be cut needs to be symmetrically processed by n being 10, the thickness of the workpiece is 3mm, the precision of the workpiece is +/-0.02 mm, the roughness of the workpiece is 0.8mm, the workpiece needs to be clamped and aligned by using the traditional dividing head for 10 times, and the workpiece needs to be water-cooled due to the nature of a linear cutting (slow wire moving) machine tool, and the dividing head is rusted after being used up, namely the precision and the wall thickness H of the part cannot be guaranteed to be 0.35 +/-0.02 mm.

Therefore, in a preferred embodiment of the present invention, as shown in fig. 1 and 2, a regular icosahedral prism 1, which is 2 n-20, is invented, a square groove 2 with a thickness of 3mm is machined at the center of one plane of the regular icosahedral prism 1, and the symmetry axis of the square groove forms an angle θ of 180 °/20 ° with the symmetry axis of the regular icosahedral prism 1.

The wire-electrode cutting processing frock is with waiting to cut a right-hand member phi 20 excircle centering, 24X 24mm orientation, the fixed platform of waiting to cut the work piece and square groove 2 butt and fix with the screw, save the time of dress card alignment at every turn during wire-electrode cutting processing, as long as it just can to wear the silk at every turn, wire-electrode cutting processing has just so saved two-thirds time, part size precision has been guaranteed after the processing, the tolerance requirement, thereby avoided leading to its rust because of using the dividing head and causing the problem that the precision can not guarantee the part precision.

In a preferred embodiment of the invention, a through hole 3 with a diameter of phi 18 is further processed in the regular twenty-prism body 1 along the axial direction so as to reduce the weight of the wire-electrode cutting processing tool.
