Abstract

The utility model discloses a can restore multi-wire saw guide pulley, wherein, connect the hole including the equipment main shaft, the equipment main shaft connects the hole to be a column hole, the downthehole lantern ring of installing of column, the lantern ring height with column hole depth is the same. The utility model provides a prior art guide pulley can only use once problem, connect the hole to set up to the column hole through the main shaft of equipment to at the downthehole lantern ring of installing of column, make the guide pulley can be after wearing and tearing are serious, the cost has been practiced thrift greatly in the reprocess use.

Description

Repairable guide wheel of multi-wire cutting machine

Technical Field

The utility model relates to a cutting machine guide pulley especially relates to a can repair multi-wire saw guide pulley.

Background

With the continuous development of photovoltaic, semiconductor and LED industries, a multi-wire cutting method is mostly adopted to cut a bar to be processed into a sheet product with a certain thickness. In multi-wire cutting machines, the guide wheel has an important role as a carrier for the cutting wire. And usually along with the guide pulley is constantly used, the conical surface that guide pulley and cutting machine assembly were can receive wearing and tearing, when wearing and tearing are serious, can influence the installation accuracy of guide pulley greatly, and then influence cutting quality. FIG. 1 is a cross-sectional view of a prior art tapered bore of a guide wheel; the guide wheel which is worn seriously can only be discarded, and the cost for buying a new guide wheel again is high, thereby greatly increasing the use cost of users.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a can repair multi-wire saw guide pulley for solve among the prior art problem that the guide pulley can only use once.

The above object of the present invention is achieved by the following technical solutions:

the guide wheel of the repairable multi-wire cutting machine comprises an equipment main shaft connecting hole which is a cylindrical hole, a lantern ring is installed in the cylindrical hole, and the height of the lantern ring is the same as the depth of the cylindrical hole.

The repairable guide wheel of the multi-wire sawing machine, wherein the outer wall of the lantern ring is in interference fit with the inner wall of the cylindrical hole.

The repairable guide wheel of the multi-wire cutting machine, wherein the inner wall of the collar is an inner conical surface.

In conclusion, owing to adopted above-mentioned technical scheme, the utility model provides a prior art guide pulley can only use once problem, through connect the hole with equipment main shaft to set up to the column hole to at the downthehole lantern ring of installing of column, make the guide pulley can be after wearing and tearing are serious, the cost has been practiced thrift greatly in the reprocessing use.

Drawings

FIG. 1 is a cross-sectional view of a prior art tapered bore of a guide wheel;

fig. 2 is a schematic sectional view of the structure of the guide wheel of the repairable multi-wire saw of the present invention.

Detailed Description

The invention will be further described with reference to the following figures and examples:

fig. 2 is a schematic sectional view showing the structure of the repaired guide wheel of the multi-wire cutting machine of the present invention, please refer to fig. 2, which is a guide wheel of the repaired multi-wire cutting machine, wherein the guide wheel comprises a hole for the main shaft of the equipment, the hole for the main shaft of the equipment is a cylindrical hole 2, a sleeve ring 3 is installed in the cylindrical hole 2, and the height of the sleeve ring 3 is the same as the depth of the cylindrical hole 2. The utility model discloses with the taper hole replacement among the prior art for column hole 2 adds the structure of lantern ring 3 for the wearing and tearing position has become lantern ring 3, thereby has overcome the problem of disposable.

Furthermore, after the service life of the lantern ring 3 is reached, the lantern ring 3 which is worn excessively can be removed again through an internal grinding machine or turning, and a new lantern ring 3 is installed again, so that the recycling is realized.

Further, the outer wall of the lantern ring 3 is in interference fit with the inner wall of the columnar hole 2.

Further, the inner wall of the lantern ring 3 is an inner conical surface.

Further, through the structure of this application, can also realize the restoration of current guide pulley 1, concrete step is as follows:

1. turning off the severely worn taper holes at two ends of the guide wheel 1 to form cylindrical straight holes, wherein the inner diameter of each straight hole is generally plus 5-15 mm of the major diameter of each taper hole, and the depth of each straight hole is the depth of the original taper hole;

2. processing and manufacturing a substituted taper hole lantern ring 3, wherein the outer diameter of the lantern ring 3 and the inner diameter of the cylindrical straight hole turned in the previous step form large interference fit, the height of the lantern ring 3 is consistent with the depth of the taper hole, and the inner side of the lantern ring 3 is an inner conical surface which is consistent with the taper of the taper hole to be repaired and has a small diameter;

3. assembling the taper hole lantern ring 3 into the straight holes turned at the two ends of the guide wheel 1 by a hot expansion and cold shrinkage method;

4. and grinding the inner conical surface of the embedded tapered hole lantern ring 3 to the required size by an internal grinder.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without inventive faculty, or through software programming. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.

Claims
