Convex feeding system of roll grinder

Abstract

The invention relates to the technical field of a roll grinder device for machining, in particularly to a convex feeding system of a roll grinder. The convex feeding system of the roll grinder comprises of a transverse sliding base and a grinding wheel box body, a bearing shaft is arranged between the grinding wheel box body and the transverse sliding base, the bearing shaft is fixedly connected with the transverse-sliding base, two ends of the bearing shaft are separately arranged on the lower portion of the grinding wheel box body through a first tapered roller bearing and a second tapered roller bearing, and a spindle assembly is arranged on the front side of the grinding wheel box body; an eccentric cam box is arranged on the transverse sliding base, one end of a swing frame is in contacted connection with the eccentric cam box through a bearing rod and an bearing, the other end of the swing frame is arranged on a support through a shaft, and the support is arranged on the transverse sliding base; the upper end of a sliding frame is arranged on the upper portion of the grinding wheel box body through a slight-adjusting screw, the grinding wheel box body at the upper end of the sliding frame is provided with a cap correspondingly, and an elastic bearing roller corresponding to the swing frame is arranged at the lower end of the sliding frame. The convex feeding system of the roll grinder has the advantages that accuracy and rigidity of transmission are improved, requirement for strong grinding of the roll grinder is met, and high productivity and equipment loading rate are achieved.

Description

technical field [0001] The invention relates to the technical field of roll grinder equipment in mechanical processing, in particular to a convex feeding system of a roll grinder. Background technique [0002] In the horizontal convex feeding device of the roll grinder in the prior art, its structure usually uses the carriage to drive the grinding wheel frame to move longitudinally, so that the cam rotates, and the swing frame rotates around the fulcrum, so that the carriage and the grinding wheel frame swing along the supporting point. The bearing seat of the support point is connected with the grinding wheel frame separately to make a slight swing. The disadvantage of this structure is that the rigidity of the system structure is poor, and vibration is generated during grinding, which leads to feed crawling of the convex feed device and a decrease in grinding accuracy, which affects the surface processing quality and grinding accuracy of the machine tool; at the same time,...

The disadvantage of this structure is that the rigidity of the system structure is poor, and vibration is generated during grinding, which leads to feed crawling of the convex feed device and a decrease in grinding accuracy, which affects the surface processing quality and grinding accuracy of the machine tool; at the same time, it affects the cutting efficiency and grinding accuracy of the roll grinder. Performance indicators such as energy consumption; it cannot meet the requirements of higher productivity and equipment load rate, which affects the need for strong grinding of roll grinders
