External diameter grinding machine pressurized by cylinder

Abstract

The invention provides an external diameter grinder which is pressurized by a cylinder; the large guide roller seat (9) of the grinder is provided with a pressurization device which consists of a cylinder (1), a supporting plate (2), a flexible compressing device (3), a pneumatic element box (10), a pressure gauge (11) and a manual valve (12); three cylinders are fixed on the supporting plate which can move forwards and backwards; the supporting plate, the pneumatic element box, the pressure gauge and the manual valve are arranged on the large guide roller seat and control the cylinders by connection pipelines; the piston rod extending end of the cylinder is connected with the flexible compressing device, thus driving the flexible compressing device to move upwards and downwards; during the grinding process, after the distance of a large guide roller (8) and a small guide roller (7) is adjusted, bearing rings (6) are sequentially piled one by one; three oilstones (5) and a splint (4) are arranged on the bearing rings; according to the size of the external diameter and the requirement of coarse grinding and fine grinding, the pressure and the up-down stroke of the cylinder are adjusted; the pressure is middle so as to lead two fulcrums of the three flexible compressing devices to be supported at the middle positions of respective splint symmetrically, thus carrying out the grinding of the external diameter.

Description

technical field [0001] The invention belongs to the technical field of outer diameter grinders, in particular to an outer diameter grinder pressurized by a cylinder. Background technique [0002] The outer diameter grinding machine is a very economical and practical finishing equipment. Using this machine to grind the outer diameter of bearing rings is a finishing method commonly used in bearing production. As we all know, the outer diameter of the outer ring of the bearing is used as the reference plane for groove processing. After grinding, grinding can greatly improve its geometric accuracy, reduce surface roughness, and provide a finishing reference for subsequent processes. [0003] The grinding principle of the outer diameter grinder is as follows: figure 1 shown. When working, the workpiece is placed between the large and small guide rollers, and the pressure F generated by the pressure device acts on the oil stone, and the two guide rollers rotate in the same direc...

Problems solved by technology

[0006] For the processing of large outer diameter ferrules, such as the outer diameter grinding machine with a diameter of φ150~φ300mm, the weight pressurization method is no longer practical

Because the outer diameter of the ferrule is increased, the outer diameters of the two guide rollers are also increased correspondingly, and the adjustment distance of the pressure center position is increased a lot. Therefore, the complexity of the two sets of slider mechanisms is increased. As a result, the structure of the whole machine is huge, the manufacturing process is complicated, the adjustment operation is troublesome, and the use is very inconvenient
