Description

Indexing device for blade die based on wire cut electrical discharge machining

Technical Field

The utility model relates to a wire-electrode cutting indexing means, concretely relates to indexing means based on spark-erosion wire cutting is used for blade mould is applicable to some parts that need surely distribute the groove on the circumference.

Background

In the process of machining parts, linear cutting is a frequently-used machining mode, but the existing linear cutting machine tool cannot rotate around the center of a workpiece for one circle, the requirement cannot be met by the currently frequently-used machining mode for the workpieces needing to be grooved on the circumference, and the machining precision of the parts can be influenced by secondary clamping. Although the prior domestic numerical control dividing head has a relatively perfect specification system, the numerical control dividing head has the following defects:

1. the volume is large, and some small-sized wire cutting equipment cannot be installed.

2. High cost and difficult maintenance.

To sum up, the utility model designs a indexing means for blade mould based on spark-erosion wire cutting.

The utility model aims at providing a be used for indexing means of blade mould based on spark-erosion wire cutting, structural design is reasonable, and easy operation is convenient, has improved the machining precision, and is small, simple to operate maintains simply, and the practicality is strong.

In order to achieve the above purpose, the present invention is realized by the following technical solution: indexing means for blade mould based on spark-erosion wire cutting, including the indexing means body, the indexing means body include spring, clamp plate, first screw, graduated disk, second screw, bearing, axle, fixed plate and rolling disc, the indexing means body pass through the fixed plate and install on spark-erosion wire cutting equipment, the work piece passes through clamp plate and first fix with screw on the rolling disc, is provided with the V-arrangement piece on the rolling disc, the graduated disk on be provided with a plurality of V-arrangement grooves, the V-arrangement piece cooperatees with the V-arrangement groove, the graduated disk passes through the second fix with screw on the fixed plate, graduated disk and rolling disc wear to establish epaxially in proper order, locking nut locking is passed through to axle one end, the spring has still been cup jointed through the bearing to the axle.

Preferably, the bearing is externally sleeved with a rotating disc.

Preferably, the other end of the shaft is T-shaped in cross section, and a spring is provided between the T-shape and the bearing 7.

Preferably, the V-shaped grooves are uniformly distributed on the outer edge of the dividing plate.

The utility model has the advantages that: the utility model has the advantages of reasonable design, easy operation is convenient, has improved the machining precision, and is small, simple to operate maintains simply that the practicality is strong.

Drawings

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments;

fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural view of the index plate of the present invention.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1-2, the following technical solutions are adopted in the present embodiment: indexing means for blade mould based on spark-erosion wire cutting, including the indexing means body, the indexing means body include spring 2, clamp plate 3, first screw 4, graduated disk 5, second screw 6, bearing 7, axle 8, fixed plate 9 and rolling disc 10, the indexing means body pass through fixed plate 9 and install on spark-erosion wire cutting equipment, work piece 1 passes through clamp plate 3 and first screw 4 to be fixed on rolling disc 10, is provided with the V-arrangement piece on the rolling disc 10, graduated disk 5 on be provided with a plurality of V-arrangement grooves, the V-arrangement piece cooperatees with the V-arrangement groove, graduated disk 5 passes through second screw 6 to be fixed on fixed plate 9, graduated disk 5 and rolling disc 10 wear to establish on axle 8 in proper order, axle 8 one end is locked through lock nut 11, still has cup jointed spring 2 through bearing 7 on the axle 8.

It is noted that the bearing 7 is externally sleeved with a rotating disc 10.

It is noted that the cross section of the other end of the shaft 8 is T-shaped, and the spring 2 is arranged between the T-shaped and the bearing 7.

In addition, the V-shaped grooves are uniformly distributed on the outer edge of the dividing disc 5.

The indexing device of the embodiment is arranged on the wire cut electric discharge machine through the fixing plate 9, and when the cylindrical surface of the workpiece 1 needs to be cut and uniformly distributed, the workpiece is fixed on the rotating disc 10 by using the pressing plate 3 and the screws 4. A certain number of V-shaped grooves are formed in the index plate 5, the workpiece 1 is positioned through the V-shaped grooves in the index plate 5, a V-shaped block matched with the index plate 5 is arranged on the rotating plate 10, after one groove of the workpiece 1 is machined, the rotating plate 10 is pulled outwards to enable the V-shaped block to exit from the V-shaped groove, and then the rotating plate 10 is rotated to a corresponding position to machine the next groove. In order to facilitate the rotation of the rotary disk 10, the rotary disk 10 can be pulled out and pushed tightly by the compression and extension of the spring 2. The indexing disk is fixed on a fixing plate 9 through a screw 6.

The structure of the specific embodiment is small and exquisite, is suitable for installation and use of small-sized wire cutting equipment, and has low cost, simple maintenance, convenient and reliable use and strong practicability.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
