Secondary driving device for heavy numerical control roller grinder

Abstract

The invention discloses a secondary driving device for a heavy numerical control roller grinder. A driving mechanism of the roller grinder can drive a roller to rotate through first, second, and third belt pulleys; one end of a universal coupling can be detachably and fixedly positioned on a rotating shaft of the second belt pulley, while the other end is fixedly positioned on a rotating shaft of a fourth belt pulley; the fourth belt pulley drives a fifth belt pulley; the other end of a rotating shaft of the fifth belt pulley is connected with one end of a connecting disc; the other end of the connecting disc is flexibly and fixedly connected with two shifting blocks; the diameter of the fourth belt pulley is greater than that of the fifth belt pulley; the fourth and fifth belt pulleys can be rotationally and axially positioned on first and second supports in a locking way respectively; the lower ends of the first and second supports can be positioned on a pedestal in a radially-sliding and axially-fixed manner respectively; and the pedestal can be detachably and fixedly arranged on the body of the roller grinder. Thus, the rotating speed of the roller is increased and the aim of grinding rollers with various diameters can be fulfilled. The secondary driving device has the advantages of improving production efficiency, saving capital and plant space, along with small occupied space, convenient assembly and disassembly.

Description

technical field [0001] The invention relates to an auxiliary mechanism of a roll grinder, in particular to a second driving device of a heavy-duty numerical control roll grinder. Background technique [0002] At present, due to the different roll specifications, the traditional CNC roll grinder is mainly used for grinding rolls with large diameter and heavy weight. Due to the limitation of the headstock speed and the adjustment range of the dial, when grinding rolls with a smaller diameter, the roll The linear speed of the surface is too small to meet the grinding requirements. In order to grind rolls with smaller diameters, it is necessary to purchase a small roll grinder suitable for grinding such rolls, which wastes money and takes up workshop space, and is very inconvenient to use. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a second driving device for a heavy-duty numerically controlled roll grinde...
