The angle grinding is usually performed by a master with considerable experience. Engaged. It is not easy for general technicians to grasp the best techniques for grinding drilling tools, and the drilling of drilling tools often has problems of difficult to grasp quality and difficult to succeed. As shown in the sixth figure, a half-moon drill reamer is used as an example. It is currently used in the industry for drilling tool grinding jigs (9). Most of them use ready-made inner hole shanks, or simple self-made jigs such as fixed seats. (9 〇) _ An extension rod (9 1) is penetrated at the end, a perforation (9 2) is set at the leading edge of the extension rod (9 1), and a drilling tool (9 3) is set in the perforation (9 2) —tungsten steel circle A screw (9 4) into the front edge of the extension rod (9 丄) and penetrating into the perforation (9 2), so that the front end of the screw (9 4) can abut against the surrounding surface of the drilling tool (9 3) For positioning, the inner hole shank or drilling tool grinding jig (9, can be set on the knife holder of the sharpener positioning base (80), the upper edge of the knife positioning base 4 M275916 (80) θ is again Place a bottom plate (81), a clamping plate (82), and screw into the bottom plate (8, 1) with a screw portion provided at the bottom end of a holding screw (8 4), and set a screw (8 3) to resist The drilling tool grinding jig (9) is positioned and clamped on the bottom plate (8 ，), so that it can adjust the required angle with the sharpener, and the diamond grinding wheel of the sharpener can be used for tungsten steel circles. The drilling tool (9 3) is used for grinding. The above-mentioned drilling tool grinding jig (9) is used for the installation of the spring-scale steel round rod for the drilling tool (9 3), and it is only locked by the front end of the screw (9 4). On the circumferential surface of the drilling tool (9 3), there is a problem that it is not easy to accurately position it. Moreover, for the grinding of the arc angle of the composite surface of the drilling tool (9 3), grasp the drilling tool (9 3) by hand. ) The rear end is rotated, and if the diameter of the drilling tool (9 3) is small, a slight rotation change of the drilling tool (9 3) will cause the arc angle of the grinding to be greatly changed, and the arc angle will not be easy. Moreover, the failure rate is very high, and the size of the perforation of the jig is fixed, and there are very few types of tools that can be ground with "'' to meet the needs of dimensional changes." [New content] Do not design / / "can drill holes The cutter is positioned to grind at a specific fe ΤΤΓ W 疋 angle, with a variety of dimensional changes, and high precision. __ 口 ”This person can apply this force, and can grind the porous cutter 'J' to complete as long as it is disassembled Yes, at the same time, it is easy to synthesize the arc angle of the surface and the cutting edge The center point can be accurately controlled within 0.01 „to make the drilling ability more accurate.
