Description

Technical Field

[0001] This invention relates to a method for high-precision diamond roller arc dressing. Background Technology

[0002] The use of cemented carbide materials in mechanical manufacturing processes is becoming increasingly widespread, and the consideration of machining methods for cemented carbide workpieces has become an important research topic. Cemented carbide materials have high hardness but are relatively brittle, often prone to cracking during machining. Since cemented carbide materials are frequently used to manufacture precision cutting tools, which generally require very high dimensional and positional tolerances, diamond rollers are commonly used in our actual production processes to machine cemented carbide tools to meet these tolerance requirements. Chinese invention patent CN201210343904.5 discloses a diamond roller dressing tool and method. Its structure is simple and reasonable, enabling rapid and automatic dressing of diamond grinding wheels at the production line, eliminating the high cost of outsourcing diamond grinding wheels to professional manufacturers for repair.

[0003] However, such diamond rollers are prone to slipping when machining compressor vanes, resulting in poor machining effects. Therefore, the inventors improved the diamond rollers to achieve the following: Figure 2 The diamond roller shown has a stepped structure on the edge of the grinding wheel. However, in the prior art, especially the technical solution disclosed in the above-mentioned prior art, the stepped structure will cause serious mechanical interference, making it difficult to perform high-precision dressing of such diamond roller with stepped edge. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a high-precision diamond roller arc trimming method. This high-precision diamond roller arc trimming method can effectively trim diamond rollers with stepped structures on the edge of grinding bars with high precision, so as to restore them to the ideal contour, and can effectively avoid mechanical interference.

[0005] The present invention is achieved through the following technical solutions.

[0006] This invention provides a high-precision diamond roller arc dressing method, comprising the following steps:

[0007] S1. Clamping: The diamond roller with a stepped structure on the edge of the grinding bar is rotatably clamped and fixed.

[0008] S2. Align the step: Align the dressing wheel with the step structure that is close to the diamond roller, and start the grinding wheel to rotate;

[0009] S3, Arc Rotation Dressing: Move the grinding wheel along the diamond roller grinding strip in an arc path, so that the grinding wheel crosses the diamond roller grinding strip for dressing, until the grinding wheel is close to the stepped structure of the diamond roller.

[0010] S4, Lateral Step: Rotates the grinding wheel by one step unit;

[0011] S5. Determine the top edge: Determine whether the diamond roller has rotated a full circle. If so, proceed to the next step; otherwise, return to step S3.

[0012] S6. Reset and release: Remove and reset the grinding wheel, remove the diamond roller, and complete the single processing.

[0013] The diamond roller has a layer of diamond particles on its grinding wheel.

[0014] The thickness of the diamond particle layer is 0.2-0.3 mm, and the roundness is ≤0.002 mm.

[0015] In step S1, the diamond roller is horizontally clamped and fixed.

[0016] In step S3, the grinding wheel is moved vertically along an arc path.

[0017] In step S3, the center of the arc path of the moving grinding wheel coincides with the center of the arc structure of the diamond grinding wheel.

[0018] The diamond roller has a circular structure, and the grinding bar is located on the vertical center line of the outer edge of the ring.

[0019] The radial length of the diamond roller is 6 times its axial length.

[0020] The beneficial effects of this invention are: it can effectively and precisely dress diamond rollers with stepped edges to restore their ideal contours, achieving high precision and ease of operation, and effectively avoiding mechanical interference. Thus, it can dress diamond rollers used for processing compressor vanes at extremely low cost, significantly reducing the processing cost of compressor vanes. Attached Figure Description

[0022] Figure 2 This is a schematic diagram of the diamond roller structure in this invention. Detailed Implementation

[0023] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0024] At least one embodiment of the present invention relates to, for example Figure 1 The high-precision diamond roller arc dressing method shown includes the following steps:

[0025] S1. Clamping: The diamond roller with a stepped structure on the edge of the grinding bar is rotatably clamped and fixed.

[0026] S2. Align the step: Align the dressing wheel with the step structure that is close to the diamond roller, and start the grinding wheel to rotate;

[0027] S3, Arc Rotation Dressing: Move the grinding wheel along the diamond roller grinding strip in an arc path, so that the grinding wheel crosses the diamond roller grinding strip for dressing, until the grinding wheel is close to the stepped structure of the diamond roller.

[0028] S4, Lateral Step: Rotates the grinding wheel by one step unit;

[0029] S5. Determine the top edge: Determine whether the diamond roller has rotated a full circle. If so, proceed to the next step; otherwise, return to step S3.

[0030] S6. Reset and release: Remove and reset the grinding wheel, remove the diamond roller, and complete the single processing.

[0031] This allows for effective and high-precision dressing of diamond rollers with stepped edges on grinding bars, restoring them to their ideal contours. The process is highly precise, easy to operate, and effectively avoids mechanical interference from the stepped structure. Instead, it utilizes the stepped structure to improve precision, thus achieving the dressing of diamond rollers used for machining compressor vanes at extremely low cost, significantly reducing the processing cost of compressor vanes.

[0033] Furthermore, the thickness of the diamond particle layer is 0.2-0.3 mm, and the roundness is ≤0.002 mm.

[0034] Furthermore, in step S1, the diamond roller is horizontally clamped and fixed.

[0035] Furthermore, in step S3, the grinding wheel is moved vertically along the arc path.

[0036] Furthermore, in step S3, the center of the arc path of the moving grinding wheel coincides with the center of the arc structure of the diamond grinding wheel.

[0037] Furthermore, the diamond roller has a circular structure, and the grinding bar is located on the vertical center line of the outer edge of the ring.

[0038] Furthermore, the radial length of the diamond roller is 6 times its axial length.
