Blade grinding machine for external conical surface of drill

Abstract

The invention discloses a blade grinding machine for an external conical surface of a drill, belonging to the technical field of advanced manufacturing system and numerical control machining. The blade grinding machine is controlled by employing a motor and a servo system; a main shaft block is driven by a first guiding device to move in the first direction, while a tool rest mounting base is driven by a second guiding device to move in the second direction; and then a tool rest is rotated by a tool rest driving motor and a main shaft is rotated by a main shaft driving motor, so that a four-dimensional numerical control technology of drill blade grinding is realized and the running of the blade grinding machine provided by the invention is very flexible; in addition, a human-machine operation interface of the blade grinding machine is visual so that the change in the drill blade grinding process can be directly observed; the machine is high in running speed and accurate in angle; any grinding angle of the drill can be adjusted; the difficulty in drill angle adjustment during processing is completely solved; and the blade ground surface of the drill after grinding is bright; therefore, the quality problem of short service life of the drill in the production process is effectively improved; the utilization rate of the drill is greatly brought into play; and the processing efficiency of a product is improved.

Description

technical field [0001] The invention relates to a sharpening machine for the outer cone surface of a drill bit, which adopts four-dimensional numerical control technology and is controlled by a stepping motor and a servo system, and belongs to the technical field of advanced manufacturing systems and numerical control processing. Background technique [0002] The grinding machines used in the existing market basically adjust the grinding angle manually, but there are some technical problems in manual adjustment, such as uneven angle distribution, the angle cannot be adjusted at will during the drilling process, and the back angle of the drill bit cannot be controlled by the processing equipment. It is difficult to meet the quality requirements of the drill bit processed in this way, the service life is short, and the processing efficiency is also very low. Contents of the invention [0003] In order to solve the above problems, the present invention provides a drill bit ou...
