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

[0055] combine figure 2 and image 3 , a kind of emery wheel interpolation dressing mechanism of the present embodiment, comprises diamond pen 100, grinding wheel 200, rotating unit 300, and wherein diamond pen 100 is fixedly installed on the rotating arm 304 of rotating unit 300, and this rotating arm 304 and rotating unit 300 The rotating shaft 303 of the servo motor 301 is connected. The rotation of the servo motor 301 drives the rotating arm 304 to rotate, and then drives the diamond pen 100 to rotate, thereby trimming the grinding wheel 200 on the workbench, and the entire rotating unit 300 is fixedly installed on the upper pallet 400, which is located on the on the workbench.

[0056] The diamond pen 100 is controlled by the servo motor 301 with the rotating shaft 303 as the center of a circle, and the distance between the central axis of the diamond pen 100 and the central axis of the rotating shaft 303 is used as a radius to rotate. This rotation can be a circular r...

Embodiment 2

[0064] combine figure 2 , a grinding wheel interpolation dressing mechanism of this embodiment is basically the same as that of Embodiment 1, the difference is that: this embodiment is equipped with a longitudinal sliding guide rail 600 on the lower pallet 700, and is provided with a sliding rail on the upper pallet 400. The longitudinal sliding guide rail 600 cooperates with the slideway to facilitate the longitudinal feed motor 501 to control the axial movement of the upper supporting plate 400 along the grinding wheel 200 .

[0065] In this embodiment, in order to further ensure the smooth operation of the diamond pen 100, a reducer 302 is integrated on the servo motor 301, and the servo motor 301 and the reducer 302 cooperate to drive the diamond pen 100 to swing.

[0066] As a preference, the reducer 302 in this embodiment adopts a planetary reducer with high transmission efficiency, low noise and long life.

[0067] The rotating arm 304 in this embodiment can be instal...

Embodiment 3

[0071] combine figure 2 , a grinding wheel interpolation dressing mechanism of this embodiment is basically the same as that of Embodiment 2, the difference is that: the vertical sliding guide rail 600 in this embodiment is horizontally arranged on the upper surface of the lower pallet 700, and the slideway is arranged on the upper surface On the lower surface of the supporting plate 400, the two cooperate with each other to facilitate the movement of the upper supporting plate 400.

[0072] In addition, in this embodiment, holes are provided on the bottom surface of the casing of the servo motor 301 and the upper supporting plate 400, and the bolts pass through the two holes to fix the servo motor 301 on the upper supporting plate 400, that is, the servo motor 301 is vertically fixed. The rotating unit 300 is fixed on the upper support plate 400 through double fixing in horizontal and vertical directions.

[0073] combine Figure 4 , Figure 5 and Figure 6 , the fine-tu...

Abstract

The invention discloses a dressing method of a grinding wheel interpolation dressing mechanism, and belongs to the technical field of grinding wheel dressing. The grinding wheel interpolation dressingmechanism comprises a diamond pen, a rotating unit, an upper supporting plate, a longitudinal feeding unit and a lower supporting plate; the diamond pen is mounted on a rotating arm of the rotating unit; the rotating arm is connected with a servo motor of the rotating unit and drives the diamond pen to rotate through the servo motor to dress to-be-machined grinding wheels; the rotating unit is fixedly mounted on the upper supporting plate, the upper supporting plate is slidably connected with the lower supporting plate, and the sliding direction of the upper supporting plate is perpendicularto the diamond pen; and the longitudinal feeding unit is mounted on the lower supporting plate and used for driving the upper supporting plate to move. The rotating radius of the diamond pen is set tobe a fixed value, the diamond pen cooperates with a driving motor to be used, and thus a needed motion trail is obtained, so that the different grinding wheels are subjected to interpolation dressing.

Description

technical field [0001] The invention relates to the technical field of grinding wheel dressing, and more specifically, relates to a dressing method of a grinding wheel interpolation dressing mechanism. Background technique [0002] With the gradual improvement of market requirements for bearing quality, in the grinding of inner and outer rings and rollers of roller bearings, most of the contact surfaces are required to have a certain slight convex shape, that is, in the inner ring, outer ring, The rollers must have a certain convex shape, which is called "three convex" in the industry. This is because when the bearing is running, there is a large contact stress concentration phenomenon at the edge of the raceway, causing most of the damage of the bearing 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, most of the industry adopts this convex raceway. In addition, the design of the conve...
