A method for dressing the inner concave arc surface of a diamond roller

Abstract

The application provides a dressing method for an inner recessed circular arc surface of a diamond roller, and solves the technical problems of high dependence on tool grinding wheel profile accuracy, uneven tool grinding wheel wear, poor dressing path retention, and low dressing accuracy of existing roller dressing methods. The dressing method makes the diamond roller and the tool grinding wheel rotate around a parallel axis, and a grinding point on a profile line of a grinding surface of the tool grinding wheel is tangent to a profile line of the inner recessed circular arc surface of the diamond roller. At each grinding point, the diamond roller is controlled to perform reciprocating swing dressing, and the range of swing dressing covers the entire inner recessed circular arc surface. The dressing method reduces the dependence on the profile accuracy of the tool grinding wheel, and also reversely dresses the tool grinding wheel during the dressing process, thereby improving the dressing path retention, improving the dressing accuracy of the diamond roller, and being suitable for dressing of almost all inner recessed circular arc surfaces and effectively avoiding interference during the dressing process.

Description

Technical Field

[0001] This invention relates to the field of diamond roller dressing technology, and in particular to a method for dressing the concave arc-shaped surface of a diamond roller. Background Technology

[0002] With the development of industrial technology and the increasing precision requirements, various ultra-high precision parts in the machinery industry not only have high precision requirements but also complex machining profiles. These profiles are generally composed of concave circular arc profiles, straight line profiles, or combinations thereof. Examples include turbine blade root grooves in aero-engines, linear guides, ball screws, and bearing raceways. For machining concave circular arc profiles, the current main method is profile grinding. This involves using a profile grinding wheel to achieve the machining of the workpiece in a single pass. The profile accuracy of the profile grinding wheel directly affects the machining quality of the workpiece. The accuracy of the profile grinding wheel is mainly guaranteed by diamond rollers, which are formed by copying the concave circular arc profile of the diamond roller onto the grinding wheel profile through a profile dressing process.

[0003] To meet the ultra-high precision machining requirements of workpieces, diamond rollers generally need to be dressed. The diamond roller profile is electroplated with coarse-grained diamond abrasive, and the abrasive concentration is high with good uniformity, making dressing extremely difficult. Traditional dressing methods typically use an arc-shaped diamond tool wheel for interpolation dressing. This method is highly dependent on the accuracy of the tool wheel's arc profile, but for diamond roller dressing, the tool wheel wears severely during the dressing process, and the tool wheel profile deteriorates rapidly, making it difficult to maintain accuracy and ultimately failing to achieve high-precision dressing of the diamond roller profile. Summary of the Invention

[0004] To address the shortcomings of the aforementioned background technology, this invention proposes a method for dressing the concave arc surface of a diamond roller, which solves the technical problems of existing roller dressing methods, such as high dependence on the profile accuracy of the tool grinding wheel, uneven wear of the tool grinding wheel, poor dressing path retention, and low dressing accuracy.

[0005] The technical solution of this application is as follows:

[0006] A method for trimming the concave arc surface of a diamond roller includes the following steps:

[0007] Step 1: Define the rotation axis of the diamond roller as the X-axis, the rotation axis of the tool grinding wheel as the S-axis, the feed direction of the diamond roller as the Y-axis, and the contour line of the concave arc surface of the diamond roller. The central axis is the C-axis, and the X-axis is set parallel to the S-axis;

[0008] Step 2: Inward circular arc surface oscillation dressing: Align the grinding point on the contour line of the grinding surface of the tool grinding wheel with the contour line. Tangent to each of the grinding points and the contour line When tangent, control the diamond roller to reciprocate around the C-axis for dressing. While the diamond roller is oscillating and dressing, the diamond roller rotates around the X-axis and the tool grinding wheel rotates around the S-axis, so that the range of oscillation dressing covers the entire concave arc surface.

[0009] Step 3: Control the diamond roller to feed ΔL along the Y-axis. After the feed is completed, repeat step 2 until the accuracy of the diamond roller meets the requirements.

[0010] The oscillating dressing method provided in this technical solution uses the S-axis of the tool grinding wheel, which can be a main spindle or a secondary spindle. The contour line is achieved through the oscillation of the diamond roller. Dressing is achieved by rotating a tool grinding wheel and a diamond roller to dress the entire concave arc surface. A finite number and appropriate positions of grinding points are selected on the tool grinding wheel. By oscillating the diamond roller around the C-axis, the entire concave arc surface is dressed using these finite number of grinding points. This reduces the dependence of diamond roller dressing on the precision of the tool grinding wheel's grinding surface and improves the retention of the dressing path.

[0011] Preferably, the number of grinding points in step 2 is based on the contour line. The degree of curvature and size settings, and the number of grinding points are taken as the minimum number required for the oscillation dressing range to cover the entire concave arc surface. In step 2, the number of grinding points is also related to the size and shape of the diamond roller and the size and shape of the tool wheel, the outline The deeper the bend and the larger the size, the more grinding points need to be set, and the more contour lines are required. The smaller the bending depth and the smaller the size, the fewer grinding points need to be set. On the basis of covering the entire concave arc surface with the swing adjustment range, the fewer the number of grinding points, the better.

[0012] Preferably, the number of grinding points in step 2 is 2-5. 2-5 grinding points are suitable for dressing diamond rollers of most shapes and sizes.

[0013] Preferably, when the number of grinding points in step 2 is 3, the grinding point on the contour line of the grinding surface of the tool grinding wheel is the first grinding point g. 1 Second grinding point b 1 The third grinding point h 1 The corresponding contour line The initial tangent points are g, b, and h, respectively, and these points form the contour line. The diamond rollers are divided into four equal parts at points g, b, and h, respectively, and then perform left-segment, middle-segment, and right-segment oscillation trimming. The outline... Always tangent to the first grinding point g of the tool grinding wheel 1 Second grinding point b 1 The third grinding point h 1 The diamond roller is controlled to feed the tool wheel along the Y-axis, while the tool wheel is controlled to move along the S-axis, so that the diamond roller and the tool wheel are tangent to each other sequentially at points g, b, and h. When tangent to point g, the diamond roller is controlled to swing left and right, and the tangent point on the diamond roller changes from point g to various tangent points within the swing range, realizing the dressing of the left swing range. During the correction process, the grinding point on the tool wheel is always g. 1 The methods for adjusting the middle and right swing segments are the same as those for adjusting the left swing segment.

[0014] Preferably, when performing left-segment oscillation dressing, the diamond roller is controlled to feed the tool wheel along the Y-axis, while the tool wheel is simultaneously controlled to move along the S-axis. Step 2.1: Control the first grinding point g on the contour line of the grinding surface of the tool wheel. 1 With the outline Tangent at point g; Step 2.2: Define clockwise oscillation of the diamond roller as positive and counterclockwise oscillation as negative, and control the diamond roller to oscillate clockwise around the C-axis to the contour line. The left endpoint a is the first grinding point g on the profile of the grinding surface of the tool grinding wheel. 1 The overlap is recorded as the swing angle α2; Step 2.3: The diamond roller swings counterclockwise around the C-axis, and the contour line... The left endpoint a swings to point j, with a slight gap between the left endpoint a of the diamond roller and the side of the tool wheel. The swing angle is denoted as -α1. When the left endpoint a swings to its extreme position k, the contour line... Interference occurs with the tool grinding wheel, and the swing angle is recorded as -γ, where α1 is slightly smaller than γ; Step 2.4: The swing range of the left section of the diamond roller is from -α1 to α2.

[0015] Preferably, during the mid-section oscillation dressing, the position of the diamond roller on the Y-axis is kept constant, while the tool grinding wheel is controlled to move to the right along the S-axis. Step 2.5: After the left-section oscillation dressing, the second grinding point b on the contour line of the grinding surface of the tool grinding wheel is controlled. 1 With the outline Point b is tangent; Step 2.6: Control the diamond roller to swing clockwise around the C-axis to the outline. The second grinding point b on the profile of the grinding surface of the tool grinding wheel is located at point g. 1 The overlap is recorded as β2; Step 2.7: The diamond roller rotates counterclockwise around the C-axis to the outline. The second grinding point b on the profile of the grinding surface of the tool grinding wheel is point h. 1The oscillation angle is recorded as -β1, β1 = β2; Step 2.8: The oscillation range of the middle section of the diamond roller is from -β1 to β2.

[0016] Preferably, during right-segment oscillation dressing, the position of the diamond roller on the Y-axis is kept constant, while the tool grinding wheel is controlled to move to the right along the S-axis. Step 2.9: After mid-segment oscillation dressing, the third grinding point h on the contour line of the grinding surface of the tool grinding wheel is controlled. 1 With the outline Tangent at point h; Step 2.10: Control the diamond roller to swing clockwise around the C-axis, contour line The right endpoint c of the diamond roller swings to point n, with a gap between the right endpoint c and the side of the tool wheel. The swing angle is denoted as λ2. When the right endpoint c swings to its extreme position m, the contour line... Interference occurs with the tool grinding wheel; the oscillation angle is denoted as γ, and λ2 is slightly less than γ. Step 2.11: Control the diamond roller to oscillate counterclockwise around the C-axis to adjust to the contour line. The right endpoint c is the third grinding point h on the profile of the grinding surface of the tool wheel. 1 The overlap is recorded as -λ1; Step 2.12: The right segment of the diamond roller swings from -λ1 to λ2.

[0017] Preferably, the range of the left-segment swing trimming overlaps with the range of the middle-segment swing trimming, and the range of the middle-segment swing trimming overlaps with the range of the right-segment swing trimming. The function of the overlapping transition section is to avoid the drawbacks of segmented trimming, such as missed trimming at the joint, burrs at the joint, and sharp corners.

[0018] Preferably, the radius of the profile of the grinding surface of the tool grinding wheel is r1, the radius of the motion trajectory of the center of the profile of the grinding surface relative to the diamond roller is r2, and the profile of the concave arc surface... The radius of the oscillation trajectory is R, r1 + r2 = R. The grinding point on the grinding surface of the tool grinding wheel is always tangent to the contour line of the concave arc surface, the contour line... The radius of the oscillation trajectory is the same as that of the oscillation trajectory, both being R.

[0019] Preferably, the oscillation angle of the diamond roller is an integer, and the oscillation speed and single feed rate of the diamond roller are adjustable. Using integer oscillation angles facilitates adjustment and control. The oscillation speed and single feed rate can be adjusted together or separately. When the feed rate is large, the oscillation speed should be appropriately reduced to avoid excessive heat generation and damage to the diamond roller or tool wheel.

[0020] Compared with the prior art, the technical solution disclosed in this invention has the following beneficial effects:

[0021] 1. The oscillating dressing method of this invention relies on a limited number of spaced tangent points for dressing, whereas traditional interpolation dressing methods involve the dressing path being enveloped by the movement of grinding points on the grinding surface of the tool wheel. Each point on the contour line of the concave arc surface of the diamond roller corresponds to a grinding point on the tool wheel, and all grinding points on the tool wheel's grinding surface participate in grinding. Therefore, the dressing result is severely affected by the accuracy of the contour line of the tool wheel's grinding surface. The oscillating dressing method of this invention greatly reduces the dependence of dressing on the accuracy of the tool wheel's grinding surface contour line, easily ensures the accuracy of the dressing path, and improves the dressing accuracy of the diamond roller.

[0022] 2. Traditional interpolation dressing processes cause uneven wear at various grinding points on the contour line of the tool wheel's grinding surface, leading to a deterioration in the accuracy of the tool wheel's grinding surface contour line. The oscillating dressing method of this invention, where the diamond roller oscillates back and forth along the theoretical arc, provides a reverse dressing effect on the tool wheel. During the dressing process, the accuracy of the tool wheel's grinding surface contour line gradually improves, thereby enhancing the dressing path retention.

[0023] 3. The oscillating dressing method proposed in this invention enables the diamond roller to oscillate in segments, including the oscillation mode, oscillation position, and oscillation range. It is applicable to concave arc surfaces of different sizes and depths, meets the contour line dressing requirements of almost all concave arc surfaces, and effectively avoids interference during the dressing process.
