Twist Drill Groove and Margin Combination Grinder

Abstract

The invention relates to a twist drill groove and cutting edge combined grinder which comprises a spindle, wherein a clamp head capable of clamping workpieces is arranged at the front end of the spindle; a power device capable of driving the spindle to advance, rotate and index is connected on the back section of the spindle; and a feeding device capable of conveying workpiece shafts to be processed into the clamp head is arranged in the front of the spindle. A cutting edge grinding sand wheel and a groove grinding sand wheel are respectively arranged on two sides of the front processing position of the clamp head and are respectively driven by power systems correspondingly, a rotating shaft of the cutting edge grinding sand wheel is parallel to the spindle, and a rotating shaft of the groove grinding sand wheel and the spindle form an inclination angle matched with the spiral angle of a twist drill. The twist drill groove and cutting edge combined grinder can simultaneously complete grinding of a groove and a cutting edge of the twist drill on one device through one clamping, simultaneously is low in device cost, continuous in production and high in processing efficiency, and reduces labor intensity of workers.

Description

technical field [0001] The invention relates to a twist drill processing equipment, in particular to a twist drill groove and margin combined grinding machine for processing twist drill grooves and margins. Background technique [0002] For the processing of grooves and margins of grinding drills, the methods commonly used in the prior art are: 1. Separately process the groove grinder and the margin grinder, which not only requires a lot of equipment investment, but also requires a large area of ​​equipment, and consumes manpower. Many, low processing efficiency; 2. Processing by CNC grinding machining center, this method sets multiple grinding wheels in the equipment, and one grinding wheel completes a grinding process, because the grinding wheel cannot be automatically trimmed, so it cannot be continuously produced; in addition, its The processing procedure is to process the groove first, then automatically change the tool and then grind the margin, so its processing effic...
