Knuckle bearing inner ring outer spherical surface grinding device

Abstract

The invention discloses a knuckle bearing inner ring outer spherical surface grinding device. An ejector block and a conical ring are matched to abut against and support a knuckle bearing, then a driving motor is matched with a grinding rotary drum to grind the knuckle bearing, meanwhile, a rotary disc and a positioning pipe are matched to rotate the knuckle bearing, and therefore bidirectional double-rotation tangent grinding is formed. The grinding device capable of improving grinding efficiency is characterized in that a driving box is arranged on a base, one ends of a plurality of liquid conveying pipes are arranged in the driving box at equal intervals, the other ends of the liquid conveying pipes penetrate through the driving box and extend to be arranged at one side of the driving box, and a plurality of rotating joints are arranged on the inner wall of the other side of the driving box and are correspondingly communicated with one ends of the multiple liquid conveying pipes. One end of a connecting pipe is connected and communicated with the rotating joints, and the other end of the connecting pipe penetrates through the driving box and extends to the other side of the driving box.

Problems solved by technology

[0002] Joint bearing is a kind of spherical sliding bearing. Its structure is simpler than that of rolling bearing. It is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. The surface is spherical, and it can also perform tilting motion within a certain angle range. In order to ensure the matching accuracy of the spherical surface of the spherical plain bearing during the production process of the spherical plain bearing, it is necessary to properly grind the outer spherical surface of the inner ring, because the outer spherical surface of the inner ring Due to the special spherical shape, the general manual grinding operation is more difficult. However, the existing grinding method is to directly grind the spherical surface of the inner ring through a ball mill with abrasive materials. , the rotation direction and angle of the inner ring are in a free and uncontrollable state, so in order to ensure that the spherical surface of the inner ring is completely ground, it takes a long grinding time, the entire grinding efficiency is low, and the outer spherical surface of the inner ring is prone to uneven grinding

[0003] The notification number CN104295608A discloses a method for processing the inner ring of a spherical plain bearing. The method includes the following steps: 1) using an ordinary lathe to machine the inner hole, plane and spherical surface of the blank of the inner ring of the spherical plain bearing, and the blank of the inner ring of the spherical plain bearing is a tube material; 2) Heat-treat the blank of the inner ring of the spherical plain bearing to make its hardness reach the set value; 3) Grind the plane of the blank of the inner ring of the spherical plain bearing with a surface grinder; , coarsely grind the spherical surface of the spherical plain bearing blank; 5) Grind the inner hole of the spherical plain bearing blank with an inner hole grinder; 6) Separate the inner ring of the spherical plain bearing with a spacer and arrange them in turn on the V-shaped grinding plate under the grinder In the groove, use a ball mill to grind the spherical surface to ensure the set value of surface roughness. In this inner ring processing method, the ball mill is used to perform the final fine grinding of the outer spherical surface of the inner ring, and the single-rotation grinding of the ball mill alone has low grinding efficiency.
