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 kind of double-circle tangential interpolation trimming device of the present embodiment comprises a diamond pen 100 and a rotating unit 300, wherein the diamond pen 100 is fixedly mounted on the rotating arm 304 of the rotating unit 300, and the rotating arm 304 and the 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 dressing the grinding wheel 200 on the workbench. The entire rotating unit 300 is fixedly installed on the upper supporting plate 400, and the upper supporting plate 400 is installed on the workbench.

[0058] 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. Th...

Embodiment 2

[0066] combine figure 2 and image 3 , a double-circle tangential interpolation trimming device in this embodiment is basically the same as that in 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 is connected with the first ball screw 502 through a coupling; the first screw pair 503 is installed on the first ball screw 502, and the first screw The rod pair 503 can move on the first ball screw 502, and the first screw rod 503 is fixedly connected with the upper supporting plate 400 by screws.

[0067] When the longitudinal feed motor 501 is started, 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, and then drives The upper pallet 400 moves. Since the longitudinal feed motor 501 in t...

Embodiment 3

[0078] combine figure 2 and image 3 , a double-circle tangential interpolation trimming device of this embodiment is basically the same as that of Embodiment 2, the difference being that the longitudinal sliding guide rail 600 in this embodiment is horizontally arranged on the upper surface of the lower pallet 700, and the slideway It is arranged on the lower surface of the corresponding upper pallet 400 , and the two cooperate with each other to facilitate the movement of the upper pallet 400 . The design of the horizontal sliding guide rail 900 is basically the same as that of the longitudinal sliding guide rail 600. The horizontal sliding guide rail 900 is horizontally arranged on the upper surface of the workbench, and the slideway is arranged on the lower surface of the corresponding lower supporting plate 700. The two cooperate with each other. , to facilitate the movement of the lower pallet 700.

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

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, in particular to a dressing method of a double-circle tangential interpolation dressing device. 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 convexity facil...
