Stepless speed change automatic feeding device for centerless grinder

Abstract

The invention discloses a stepless speed change automatic feeding device for a centerless grinder, which comprises a servo motor, an eccentric rotating wheel, a connecting rod, a linear guide rail, a material returning head and a base, wherein the servo motor is arranged on the base; the eccentric rotating wheel is connected with an output shaft of the servo motor; and one end of the connecting rod is connected with an eccentric hole of the eccentric rotating wheel through a bolt for the eccentric hole, and the other end of the connecting rod is arranged on the linear guide rail and is connected with the material returning head. The eccentric rotating wheel and the output shaft of the servo motor are in fastening connection through a bolt and a key, and the eccentric distance of the eccentric hole of the eccentric rotating wheel is determined according to the required material returning stroke. The stepless speed change automatic feeding device for the centerless grinder has the advantages that the servo motor is used for driving the rotating wheel and the connecting rod to operate at constant speed without other auxiliary force, so the human efficiency problem, the demagnetization problem and the material breaking and blocking problem are solved, linear operation and feeding are reliable and balanced, and the device is stepless adjustable and does not need demagnetization.

Description

technical field [0001] The invention relates to the field of design and development of a continuous automatic feeding device for a centerless mill, in particular to a stepless speed-variable automatic feeding device for a centerless mill. Background technique [0002] The feeding of materials is one of the core processes of centerless grinding machines, and it is the key to ensure continuous automatic production. The stability and consistency of the operation of the device will directly affect the quality of feeding materials, the accuracy of parts, safety, and personnel efficiency. Once the feeding speed does not If it is uniform, it will cause a large number of products to be scrapped, and it is not easy to detect, and it will cause a safety hazard when it is serious, commonly known as: "flying circle". [0003] At present, the centerless mill is usually operated by two people, one person feeds the material in series, one person picks up the material and inspects it, and a...
