Description

Technical Field

[0001] The utility model relates to the technical field of diamond products, in particular to a combined outer diamond-plated roller. Background Art

[0002] Diamond rollers are high-efficiency, long-life, low-cost grinding wheel dressing tools used in special machine tools and gear grinders for large-scale profile grinding. Diamond rollers are mainly used for grinding wheel dressing in special machine tools and grinders for profile grinding. When grinding wheels are used for grinding in traditional industries, the abrasive grains of the grinding wheel gradually become rounded and blunt under the action of friction and extrusion. As a type of profile dressing tool roller, diamond rollers are gradually recognized by the market for their excellent properties of high hardness and long life due to their diamond material, and have been widely used.

[0003] However, in the prior art, the diamond roller has a simple structure and only has a grinding function. After the diamond roller dressing work is completed, the dressed workpiece still needs to be fine-ground and polished, which reduces the practicality of the device and the processing efficiency of the workpiece. Most of them are single-piece, which limits their versatility and will affect their grinding efficiency when grinding other shapes or grinding round holes. Patent document No. 202321016796.0 discloses a multi-purpose electroplated diamond roller, which is respectively provided with a coarse grinding wheel and a fine grinding wheel, so that the fine grinding and polishing can be completed directly in one step when dressing the workpiece. Although this device can solve the problem that a single piece cannot be used for multiple purposes, the coarse grinding wheel and the fine grinding wheel are fixedly connected and the spacing cannot be adjusted, which puts higher requirements on the grinding environment and the accuracy of the workpiece matching. In addition, after this type of roller wears out, the roller needs to be replaced as a whole. The replacement of the coarse grinding wheel and the fine grinding wheel as a whole is not conducive to cost control. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a combined diamond-plated roller with adjustable spacing and reduced cost.

[0005] The technical solution adopted by the utility model to solve the technical problem is: the combined diamond-plated roller includes a fine grinding wheel and a coarse grinding wheel, the coarse grinding wheel and the fine grinding wheel are separate structures; and also includes an adjusting ring and a connecting piece.

[0006] The rough grinding wheel comprises a first base steel body, a rough grinding portion located outside the first base steel body, and an electroplating layer located on the outer layer of the rough grinding portion, wherein the first base steel body is provided with a first fixing hole;

[0007] The fine grinding wheel comprises a second base steel body, a fine grinding portion located outside the second base steel body, and an electroplating layer located on the outer layer of the fine grinding portion, wherein the second base steel body is provided with a second fixing hole corresponding to the first fixing hole;

[0008] The adjusting ring includes an annular base body. The adjusting ring is located between the rough grinding wheel and the fine grinding wheel. The connecting piece passes through the first fixing hole and the second fixing hole to connect the rough grinding wheel and the fine grinding wheel.

[0009] Further, there are multiple adjusting rings. The thickness range of each adjusting ring is 1 mm - 10 mm, and the thickness difference between the adjusting rings is 0.2 mm.

[0010] Further, a receiving groove is provided on one side of the first base steel body, and a protrusion adapted to the receiving groove is provided on the second base steel body.

[0011] Further, a semi-circular notch is provided at the edge of the adjusting ring.

[0012] Further, a rib adapted to the semi-circular notch is provided on the inner side wall of the receiving groove.

[0013] Further, connection holes corresponding to the first fixing hole and the second fixing hole are provided on the annular base body. The first fixing hole is a counterbore. The connecting piece passes through the first fixing hole, the connection hole and connects the fine grinding wheel and the rough grinding wheel through the second fixing hole.

[0014] Further, the electroplated layer is a composite electroplated layer.

[0015] This combined externally electroplated diamond roller includes an independent rough grinding wheel and a fine grinding wheel. The distance between the rough grinding wheel and the fine grinding wheel is adjusted by an adjusting ring. The adjusting ring can be used individually or in combination. By adjusting the distance between the rough grinding wheel and the fine grinding wheel, it can better adapt to the workpiece to be polished on the machine tool, and meet the requirements of polishing accuracy. In addition, the rough grinding wheel and the fine grinding wheel adopt a split structure. After one of them is worn, only the worn one needs to be replaced separately, achieving the purpose of effectively reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS
