Automatic milling cutter machining grinder

Abstract

The invention relates to an automatic milling cutter machining grinder, which comprises a body and a base arranged on the body, wherein the base is provided with a cross slide for sliding along the base is arranged on the base; a tailstock is fixedly arranged on the cross slide; a dividing head is arranged at the corresponding position of the tailstock; a workpiece is clamped by the dividing head; a grinding head is arranged above the workpiece, and is provided with a grinding wheel for grinding the workpiece. The automatic milling cutter machining grinder has the beneficial effects that 1, the whole production process is automatically controlled, and a worker can finish machining the workpiece only by clamping the workpiece once after tool setting, so that the labor intensity of the worker is reduced; 2, the body is totally sealed by a housing, so that the production environment of an operator is improved; 3, the workpiece forms an Archimedes cambered surface by virtue of a spiral tooth back machining method, so that the strength of tooth backs is strengthened, and the service life of a tool is prolonged; the front and rear angles of peripheral teeth are machined by one step, so that errors caused by repeated clamping are reduced, the quality of a product is completely ensured, and each technical index such as radial runout, roughness and dimensional accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of grinding machines, in particular to an automatic grinding machine for milling cutters. Background technique [0002] At present, in the domestic market, the most used milling cutter is still the milling cutter produced by the traditional milling process. It has the characteristics of large chip space and small grinding stress that cannot be replaced by the full grinding process. General manufacturers produce end mills and small-sized keyway milling cutters to process grooves and tooth backs with forming milling cutters after the turning process. Back, after the heat treatment process, the operator on the universal tool grinder grinds the rake face with two tops manually throwing grooves, and then grinds the two tops with a tool. . [0003] In the prior art, common universal tool grinders are used for processing, and the procedures are scattered and need two tool grinders, operated by two people. Since ...

AI Technical Summary

Problems solved by technology

Due to the manual operation, the workers have high skill requirements and high labor intensity. Dry grinding is used in the throwing process, and the grinding wheel is dusty, which is prone to occupational diseases.

The reliability of the products produced is poor, and the radial runout and surface roughness of the products cannot meet the process requirements

The ribs on the flank are processed with the outer surface of the grinding wheel to form a concave arc surface. The strength of the tooth back is poor, which affects the cutting life of the tool.
