Embodiment approach 1

[0015] A method for trimming an arc-shaped roller, comprising a roller and a grinding wheel, the roller rotates along the rotation axis of the roller, the grinding wheel rotates along the rotation axis of the grinding wheel, the roller moves left and right along the rotation of the grinding wheel, and the rotation axis of the roller is located on the intersecting straight line of the rotation axis of the grinding wheel ; On the same plane, the distance between the midpoint of the grinding wheel shaft and the midpoint of the roller shaft is not greater than the sum of the distance from the midpoint of the roller shaft to the outer circle of the roller and the distance from the midpoint of the grinding wheel shaft to the outer circle of the grinding wheel. Such as figure 2 As shown, when the roller being trimmed is a convex surface, the distance c between the midpoint of the grinding wheel shaft and the midpoint of the roller shaft is equal to the sum of the distance b from the ...

Embodiment approach 2

[0018] Specifically as in embodiment 1, the grinding wheel can also be fixed and the roller feed mode can be used for dressing. When the roller with slightly larger diameter will be trimmed, you only need to move the mobile turntable 4 to the right; when the roller with larger diameter will be trimmed, the position of the sliding crank 10 can be adjusted without changing the grinder.

[0019] The invention has long service life and small volume, can stably produce high-precision roller products in batches, has small dressing force during dressing, small wear of the dressing tool itself, and high dressing precision.

Abstract

The invention discloses a dressing method of an arc-shaped roller wheel. According to the dressing method, the roller wheel and a grinding wheel are included; the roller wheel rotates along a rotary shaft of the roller wheel, the grinding wheel rotates along a rotary shaft of the grinding wheel, the roller wheel rotates horizontally along the grinding wheel, and the rotary shaft of the roller wheel is positioned on the crossed straight line of the rotary shaft of the grinding wheel; on the same plane, the distance between the central point of the rotary shaft of the grinding wheel and the central point of the rotary shaft of the roller wheel is not greater than the sum of the distance between the central point of the rotary shaft of the roller wheel and the outer circle of the roller wheel and the distance between the central point of the rotary shaft of the grinding wheel and the outer circle of the grinding wheel. The dressing method has the characteristics that the efficiency is high, the repaired surface is relatively good, and the processing requirements of roller wheels of different sizes can be met.

Description

technical field [0001] The invention belongs to the technical field of precision machining, and in particular relates to a method for trimming an arc-shaped roller. Background technique [0002] Traditional dressing methods include diamond knife forming method and steel extrusion wheel forming method. The diamond knife forming method will not only cause errors with the theoretical value, but also requires a diamond knife with larger particles. Because large-grain diamonds are rare in my country, the price is expensive, and the repair speed is slow, which limits the general use of this method. The steel extrusion wheel forming method uses a formed high-speed steel wheel. When the grinding wheel rotates at a low speed, the radial feed contacts the grinding wheel, and slowly squeezes the grinding wheel to form a curved surface of the grinding wheel. Although this method has high efficiency and a better repair surface, the material of the steel extrusion wheel is softer than th...
