Problems solved by technology

Although this application also uses circular arc dressing, the diamond pen in this application is fixed on a small slider. During the continuous dressing process of the grinding wheel, the diameter of the grinding wheel gradually decreases. In order to ensure the same convexity on the bearing raceway, It is necessary to continuously adjust the rotating nut manually to control the horizontal distance, and then control the turning radius of the diamond pen, but it is difficult to realize in actual operation and needs further improvement

Embodiment 1

[0057] combine figure 2 and image 3 , a double-circle tangent interpolation and trimming device in this embodiment includes a diamond pen 100 and a rotating unit 300, wherein the diamond pen 100 is fixedly installed on the rotating arm 304 of the rotating unit 300, and the rotating arm 304 is connected to the rotating unit 300. The rotating shaft 303 of the servo motor 301 is connected. The rotation of the rotating arm 304 is driven by the operation of the servo motor 301 , which in turn drives the diamond pen 100 to rotate, thereby trimming the grinding wheel 200 on the worktable. The entire rotating unit 300 is fixedly installed on the upper support plate 400, and the upper support plate 400 is installed on the workbench.

[0058] The diamond pen 100 is controlled by the servo motor 301 to rotate with the rotating shaft 303 as the center of the circle and the distance between the central axis of the diamond pen 100 and the central axis of the rotating shaft 303 as the ra...

Embodiment 2

[0066] combine figure 2 and image 3 , a double-circle tangent interpolation and trimming device of this embodiment is basically the same as that of Embodiment 1, except that the longitudinal feed unit 500 in this embodiment includes a longitudinal feed motor 501, a first ball screw 502 and the first screw pair 503, wherein the longitudinal feed motor 501 and the first ball screw 502 are connected by a coupling; the first screw pair 503 is installed on the first ball screw 502, the first screw The rod pair 503 can move on the first ball screw 502 , and the first screw pair 503 is fixedly connected with the upper support plate 400 by screws.

[0067] When the longitudinal feed motor 501 is activated, the first ball screw 502 rotates, and the first screw pair 503 converts the rotational motion into a linear motion, that is, the first screw pair 503 moves on the first ball screw 502, thereby driving the The upper pallet 400 moves. Since the longitudinal feeding motor 501 in t...

Embodiment 3

[0078] combine figure 2 and image 3 , a double-circle tangent interpolation and trimming device of this embodiment is basically the same as that of Embodiment 2, except that the longitudinal sliding guide rail 600 in this embodiment is horizontally arranged on the upper surface of the lower support plate 700, They are arranged on the lower surface of the corresponding upper support plate 400 , and the two are used together to facilitate the movement of the upper support plate 400 . The design of the lateral sliding guide rail 900 is basically the same as the design of the longitudinal sliding guide rail 600. The lateral sliding guide rail 900 is arranged horizontally on the upper surface of the workbench, and the sliding track is arranged on the lower surface of the corresponding lower support plate 700, and the two cooperate with each other. , which facilitates the movement of the lower pallet 700 .

[0079] like Figure 4 and Figure 5 As shown, in this embodiment, hol...

Abstract

The invention discloses a dressing method of a double circle tangent interpolation dressing device and belongs to the technical field of grinding wheel dressing. The dressing device comprises a diamond pen, a rotating unit, a longitudinal feeding unit and a transverse feeding unit, wherein the diamond pen is arranged on a rotating arm of the rotating unit; and the diamond pen is driven by a servomotor to rotate to dress a grinding wheel on a workbench; the rotating unit is fixedly arranged on an upper supporting plate; and the upper supporting plate is in sliding connection with a lower supporting plate; the longitudinal feeding unit is arranged on the lower supporting plate and used for driving the upper supporting plate to move longitudinally; the transverse feeding unit is arranged below the lower supporting plate and is used for driving the lower supporting plate to move transversely; and the lower supporting plate is in sliding connection with the workbench. According to the dressing method of the double circle tangent interpolation dressing device, the rotation radius of the diamond pen is set as a fixed value, the diamond pen is matched with a driving motor for use, and a required movement track is obtained, so that interpolation dressing of different grinding wheels is facilitated; and in addition, the movement track of the diamond pen is jointly controlled through thelongitudinal feeding unit and the transverse feeding unit, so that the concavity of the grinding wheel dressing is guaranteed.

Description

technical field [0001] The invention relates to the technical field of grinding wheel dressing, and more particularly, to a dressing method of a double-circle tangent interpolation dressing device. Background technique [0002] With the gradual improvement of the quality requirements of the bearing in the market, in the grinding of the inner and outer rings of the roller bearing and the rollers, most of the contact surfaces are required to have a certain micro-convex shape, that is, the inner and outer rings of the bearing, The rollers all need to have a certain convex shape, which is called "three convexities" in the industry. This is because when the bearing is running, there is a large contact stress concentration at the edge of the raceway, causing most of the bearing damage to start at the edge of the raceway. In order to eliminate the concentration of edge stress and improve the working life of the raceway, this kind of convex raceway is mostly adopted in the industry...
