Description
Technical field
The utility model relates to a kind of instrument arrangement for grinding, refers to a kind of bit grinding machine particularly.
Background technology
In the bore operation of machining, drill bit is to use the highest instrument of rate, and the top sword of drill bit can wearing and tearing in the process of boring, therefore use need again behind the certain hour its reconditioning is sharp.The standard of coping drills top sword is to make the central axis symmetry of the top sword of drill bit with drill bit.If after the sword reconditioning of drill bit top not with the drill bit central axis symmetry, workpiece waved and rocks when drill bit just was difficult to aligned position, boring, make operational security reduce, the more important thing is that the undesirable size in hole site low precision, effective aperture that gets out like this, the shape in hole do not become cylindricality yet, influence the carrying out of follow-up work.
The conventional method of coping drills top sword is the bore operation, and the person hands drill bit with the sensation reconditioning, and whether the top sword is symmetrical, and entirely with range estimation, efficient is very low and the reconditioning precision is not high.Therefore, need a kind of bit grinding machine badly to overcome aforementioned disadvantages.
Summary of the invention
The purpose of this utility model is exactly that a kind of bit grinding machine simple in structure, easy to operate and with low cost will be provided, and uses it can symmetrical coping drills top sword, effectively improves grinding efficiency.
For achieving the above object, the designed bit grinding machine of the utility model comprises support, is installed in abrasive machine and drill bit guiding mechanism on the described support.Described drill bit guiding mechanism has the cylindrical shell that is vertically mounted on the support, the top nested finite angle sleeve of described cylindrical shell, be plugged with the vertical pivot of T shape seat axle in the sleeve of described limit angle, the top of described limit angle sleeve is provided with two defining flanges, and the transverse axis of described T shape seat axle is provided with the spacing positive stop that matches with described defining flange outward.Be interspersed with horizontal pulling shaft in the transverse axis of described T shape seat axle, be provided with the top cover between the transverse axis inwall of described horizontal pulling shaft and described T shape seat axle.One end of described horizontal pulling shaft is provided with the setscrew nut that the end with described top cover connects, and the other end of described horizontal pulling shaft is provided with annular ring.The inwall of annular ring is provided with the ring positioning tooth, and the other end of described top cover is provided with top cover positioning tooth, vertically is interspersed with splined shaft in the annular ring, and the key tooth of described splined shaft can and push up cover positioning tooth engagement fit with described ring positioning tooth.Also be provided with the perpendicular positioning nut on the described splined shaft, the threads engaged on described perpendicular positioning nut and the splined shaft is in order to adjust the upper-lower position relation of described splined shaft and described horizontal pulling shaft.Fixedly connected with the drill bit carrier in the two ends of described splined shaft, described drill bit carrier is corresponding with the emery wheel flour milling position of described abrasive machine.
Advantage of the present utility model is: designed bit grinding machine can be fixed with respect to the position of described horizontal pulling shaft and by the perpendicular positioning nut by adjusting described drill bit carrier up and down, with adjust drill bit and described horizontal pulling shaft from amount (being the vertical range of drill bit and horizontal pulling shaft), thereby adjustment is carried on the relief angle of the top sword of the drill bit on the described drill bit carrier; By the drill bit on the fixing described drill bit carrier of setscrew nut and the angle of described horizontal pulling shaft, thereby the angle between adjustment drill bit and the emery wheel flour milling is with the angle of decision drill bit top sword.After aforementioned angle adjustment is good, be supporting-line, drill bit be fixed on the described drill bit carrier, successively each side edge of coping drills with the line between the chip area both sides of drill bit.Because during each side edge of coping drills, the relief angle and the angle of drill bit top sword immobilize, thus drill bit top each section of sword after reconditioning is finished all around the drill bit central axis symmetry, reconditioning symmetry height.In addition, the positive stop outer by the defining flange on the sleeve of limit angle and the transverse axis of described T shape seat axle matches, and makes T shape seat axle do finite angle in the sleeve of limit angle and rotates, and is convenient to enter or withdraw from the grinding action of drill bit, and be easy to operate.And this bit grinding machine is simple in structure, with low cost, is suitable for applying.
