Special purpose grinder for piston ring helical supporting spring head face

Abstract

A grinding machine specialized for piston ring coil-spring loaded terminal surfaces relates to the grinding machine technique field of processing piston ring coil-spring loaded terminal surfaces. In the invention, a guide lever is vertically fixed at a machine frame; an upper wheel head assembly and a lower wheel head assembly are connected with the guide lever respectively; the upper wheel head assembly comprises an upper grinding disc and the lower wheel head assembly comprises a lower grinding disc; the machine frame is provided with a rotating feeder; an output terminal of the rotating feeder is connected with a rotating shaft parallel to the guide lever; the rotating shaft is fixedly connected with a cylindrical frock which is arranged between the upper grinding disc and the lower grinding disc. The invention can completely avoid the processing error owing to anthropogenic factors; therefore, the consistence of the product quality is good and steady and the processing efficiency can be raised.

Description

technical field [0001] The invention relates to the technical field of a grinding machine used for processing the end face of a piston ring spiral support spring. Background technique [0002] As we all know, the two end faces of the piston ring helical spring need to be ground to remove the end face burrs before it can be used. Because the coil spring is slender and soft, the original technology mainly relies on manual skills, with low safety and backward technology, especially the large difference in length and size. The operators of this process cannot be competent without half a year of training. In addition, some Human factors such as operator emotions also affect the quality of the process. Due to human factors in processing, it is not easy to control, resulting in unstable product quality. The current end face grinding equipment is not conducive to the expansion of reproduction of the enterprise, and directly affects the use of the piston ring spiral spring. Conten...
