Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire cutting machines, in particular to a stone wire saw winding guide wheel structure. Background Art
[0002] The guide wheel is a key part in the wire cutting machine. The satisfactory degree of processing effect is inseparable from a good, stable and precise guide wheel. The existing guide wheels are made of steel guide wheels, nylon guide wheels, polyurethane guide wheels, etc. Each material has its own advantages and disadvantages. For example, steel guide wheels have high precision but poor wear resistance. If the guide wheels are not replaced in time, the longer the cutting time, the worse the processing accuracy. Nylon guide wheels and polyurethane guide wheels are light in weight and highly flexible, but the accuracy is not easy to control and the accuracy is poor. Therefore, frequent replacement of guide wheels increases the cost of use. Summary of the invention
[0003] In order to solve the above technical problems, the utility model provides a stone wire saw winding guide wheel structure, the guide wheel structure includes a guide wheel body, a connecting shaft, a guide wheel pressure plate, a fastener, and a guide wheel rubber. The guide wheel body is provided with an axial hole, the connecting shaft is arranged in the axial hole of the guide wheel body, the guide wheel rubber is an annular structure, and the guide wheel pressure plate cooperates with the fastener to set the guide wheel rubber on the circumferential surface of the guide wheel body.
[0004] Furthermore, an L-shaped groove is provided on the guide wheel body, the fastener is a hexagon socket screw, and a first screw hole cooperating with the hexagon socket screw is provided on the guide wheel body and the guide wheel pressure plate. The guide wheel pressure plate is arranged on the L-shaped groove through the hexagon socket screw and the first screw hole.
[0005] A guide wheel film is provided outside the guide wheel body. If the guide wheel film is worn during use, the guide wheel film can be replaced at any time, reducing the cost of replacing the guide wheel. Since the guide wheel film has poor elasticity and is inconvenient to replace, an L-shaped groove is designed on the guide wheel body, and the guide wheel pressure sheet presses the guide wheel film onto the guide wheel body, making it more convenient to replace the guide wheel film.
[0006] Furthermore, the guide wheel structure also includes an axle stop, a guide wheel bearing, and a bearing cover. The connecting shaft is arranged on the guide wheel bearing, the guide wheel bearing is arranged in the shaft hole, and the axle stop and the bearing cover are arranged on both sides of the guide wheel bearing.
[0007] Furthermore, the guide wheel body includes a first guide wheel body, a second guide wheel body, and a third guide wheel body. The second guide wheel body is provided with a first groove and a second groove on both sides thereof, respectively. The first guide wheel body is arranged in the first groove, and the third guide wheel body is arranged in the second groove.
[0008] Furthermore, the guide wheel structure also includes bolts, and the first guide wheel body, the second guide wheel body, and the third guide wheel body are provided with second screw holes corresponding to each other, and the bolts fix the first guide wheel body, the second guide wheel body, and the third guide wheel body together through the second screw holes.
[0009] Furthermore, the guide wheel body and the guide wheel pressing plate are made of one or more combinations of aluminum, aluminum alloy, titanium alloy, and stainless steel, and the guide wheel rubber is made of polytetrafluoroethylene.
[0010] The advantages of guide wheel rubber made of polytetrafluoroethylene are higher strength and good wear resistance, but it has low elasticity and is not easy to install. However, the problem of difficult replacement has been solved by designing guide wheel pressure sheets and fasteners on the guide wheel body.
[0011] Furthermore, the material of the first guide wheel body and the third guide wheel body is one of polyurethane and nylon, the material of the second guide wheel body is one or more combinations of aluminum, aluminum alloy, titanium alloy, and stainless steel, and the second guide wheel body is cast in one step.
[0012] The guide wheel body is divided into a first guide wheel body, a second guide wheel body and a third guide wheel body, so as to control the total weight of the guide wheel body. The second guide wheel body is made of metal to increase the firmness of the guide wheel. The first guide wheel and the third guide wheel are arranged on both sides of the second guide wheel, so that the second guide wheel is not easily deformed when the thickness is designed to be relatively thin due to weight issues.
[0013] The utility model arranges the guide wheel rubber on the circumferential surface of the guide wheel body, which is convenient for replacement when the guide wheel rubber is worn. An L-shaped groove is arranged on the guide wheel body, and the guide wheel pressure piece is arranged on the axial surface of the guide wheel body by a hexagon socket screw, which is convenient for disassembly and replacement. The guide wheel body is arranged in three parts, which retains the firmness of the guide wheel body and is convenient for controlling the weight, so that the guide wheel body is light in weight and has small inertia when moving. The guide wheel can respond quickly during reciprocating motion and does not shake during reciprocating motion. The utility model takes into account the strength of the steel guide wheel and has wear resistance at the same time, and the service life of the guide wheel is greatly extended.
