Centerless grinder automatic plunge grinding and feeding device

Abstract

The invention relates to a centerless grinder, in particular to a centerless grinder plunge grinding and feeding device. With regard to the centerless grinder automatic plunge grinding and feeding device, an operation handle is arranged at a feedshelter; a connecting rod hinged with a piston rod of a cylinder is arranged at a symmetrical position of the feedshelter and the operational handle; thecylinder is hinged on a fixed seat and is connected with a pneumatic circuit. According to the characteristics of the plunge function of the centerless grinder, the control of grinding size of a workpiece is finished in the process that the operation handle is put down to a locating point after being put up during plunge grinding, the locating datum is more accurate, and automation can be realizedas long as the operation handle is controlled to be operated automatically. The invention changes an unstable mode into a stable mode; reduces labor intensity for operators; ensures buffing time, improves grinding stability, satisfies processing requirements on workpieces such as size, roundness, roughness and the like with 99% of product yield; increases maneuverability, realizes automatic operation in the operational process, shortens the production cycle and improves the production efficiency to 100%.

Description

1. Technical field: [0001] The present invention relates to a centerless grinding machine, in particular to a plunge grinding feeding device for a centerless grinding machine. 2. Background technology: [0002] Plunge grinding is a form of centerless grinding. Plunge grinding means that the workpiece cannot be ground as a whole, and the length of the part that needs to be ground is smaller than the width of the centerless grinding wheel. [0003] The centerless grinder has the function of plunge grinding. When the plunge grinding is performed, the operator lifts the feed handle to let the lower slide (guide wheel part) leave the grinding wheel. The process of positioning the point until the end of grinding and taking out the workpiece. [0004] During plunge grinding, the grinding process is divided into two parts: coarse grinding with large allowance and smooth grinding with small allowance. When the operating handle is placed on the positioning iron, the workpiece needs...

Problems solved by technology

[0005] Since it is impossible to ensure that the operating handle stays on the positioning iron for the same time during manual operation, the size and accuracy of the workpiece after processing cannot be guaranteed to be consistent. The quality of the workpiece is uneven, and the scrap rate increases, resulting in unnecessary waste.

[0006] The above grinding process is completely controlled by the operator, (see figure 1 ) The disadvantages are: the processing process becomes unstable due to manual operation; the labor intensity of the operator is high when working at full load; the technical requirements of the workpiece (size, surface roughness, roundness, etc.) cannot be fully met; the production efficiency is low
