During work, base is installed on the slide plate of general tool grinding machine on the plane, links together cutter and tool grinding machine slide plate T type groove and base through T type key, uses bolted again.The concrete course of work is following: the drill gun that will treat sharpening is inserted in the rack sleeve, and makes the V-arrangement face of the carbide alloy V-shaped groove applying V-arrangement locating piece partly of drill gun.Tighten the drill gun housing screw then, make the V-arrangement face of latch segment compress the arc surface of the carbide alloy of drill gun, thus drill gun is fixed.Confirm the horizontal level of a face of V-arrangement locating piece through the horizontal groove of rack sleeve lateral wall.Set the horizontal level of drill gun inner edge through the spindle index dish of sleeve bearing front end.The exterior angle set lever can make rack sleeve rotate around second rotating shaft in unclamping, and relies on inside and outside its anglec of rotation of horn craving scale adjustment.Unclamp the relief angle set lever, rack sleeve is rotated around first rotating shaft, rely on its anglec of rotation of relief angle dial adjustment.The swivel feeding handwheel can make rack sleeve around its axis rotation, relies on its anglec of rotation of spindle index dish adjustment.Select suitable half slot on the carriage, and on pressure pin, move to suitable position to carriage, hold the drill gun shank.Through above-mentioned adjustment, promptly accomplish the location of drill gun sharpening face, Mobile Slide parts then carry out sharpening with the emery wheel of cutter and tool grinding machine to drill gun.The sharpening process is specific as follows: unclamp the relief angle set lever, relief angle is transferred to required angle after, locking relief angle set lever.Grinding interior angle at first, the stock removal at exterior angle can be reduced in the exterior angle of regrinding then, and judges the end point of helicoid easily.During the grinding interior angle, the exterior angle set lever is held the feeding handwheel in unclamping, and the oscillating spindle sleeve transfers to required angle with interior angle, exterior angle set lever in the locking.Unclamp straight pin then, make the disengagement that is connected of cam and rack sleeve, hold the feeding handwheel, make the rack sleeve revolution, the horizontal groove on the rack sleeve is alignd with the zero-bit of spindle index dish, be horizontal thereby the drill gun outside is transferred to.Lock the rack sleeve lock-screw then, the slide plate of reciprocating sliding cutter and tool grinding machine lets the drill gun inner edge in the scope greater than grinding wheel width, move back and forth, and the cross slide of feeding cutter and tool grinding machine makes the drill gun inner edge progressively near emery wheel.Go out suitable inner edge until grinding.After the interior angle grinding finishes, make drill gun leave the emery wheel certain distance, the exterior angle set lever is held the feeding handwheel in unclamping, and the exterior angle is set on the required number of degrees, then exterior angle set lever in the locking.Because the spiral relief angle of drill gun outside leans on the helix of cam to generate, so the elevation angle of drill gun relief angle and inside and outside horn craving scale is irrelevant, only need unclamp the relief angle set lever, relief angle is transferred to the zero degree position get final product.During the grinding exterior angle, the precession straight pin partly runs through into the rack sleeve sidewall its inner cone, reaches gapless degree, thereby makes cam and rack sleeve position relative fixed, together rotation and feeding.Holding the feeding handwheel, drill gun outside groove plane is adjusted on the horizontal level, also is the starting point of helicoid.According to the difference of boring material, select suitable cam ring, push-and-pull roller gear level rests on the selected cam ring roller.Unclamp the rack sleeve lock-screw, rack sleeve can freely be rotated and play.Hold the feeding handwheel, promote rack sleeve forward, make cam ring near roller.The traverse feed cutter and tool grinding machine rests on the position of the about 0.5mm of drill gun outside abrasive wheel end face.After this, the feeding handwheel is only used in the no longer traverse feed of tool using grinding machine.Promote the length feed slide plate of cutter and tool grinding machine, the whole length of drill gun outside is within the abrasive wheel end face ring width.Because in the grinding process, the drill gun motion of spinning is so require the abrasive wheel end face ring width greater than drill gun outside length 5mm.Hold the rotation handwheel and push away forward, make cam ring keep no gap to contact with roller all the time, simultaneously to positive direction rotating spindle sleeve, drill gun just generates screw according to the track of cam ring like this.Rack sleeve to positive direction turn over about 120 ; Just can finish helix, rotate to negative direction (pushing away forward simultaneously) then.So repeatedly, and constantly rotate the feeding handwheel, drill gun is constantly moved to the abrasive wheel end face direction to negative direction.Again inside and outside angle is transferred to zero degree, relief angle is transferred to required angle; Main shaft is gone to-5 , relief angle that can intersection point place, the inside and outside angle of grinding.The land of the 0.1-0.2mm that its intersection point place is remaining can increase the intensity of point of a knife.Then according to the geometry of drill gun; Interior exterior angle and relief angle are transferred to required angle; Main shaft goes to+55 ; Reciprocating motion and traverse feed through the cutter and tool grinding machine longitudinal slide come to grinding oil clearance relief angle, and the intersection of angle plane and interior angle plane just in time passes through the end point of drill gun V-type groove behind the oil clearance.Based on said process, drill gun Sharpening device of the present invention has been realized the back knife face of the main cutting edge of drill gun is worn into helicoid, has thoroughly solved the problem that existing drill gun Sharpening device can't be worn into the back knife face of the main cutting edge of drill gun helicoid thus.
The present invention is based on brand-new structure, efficiently solve the problem that existing drill gun Sharpening device can't be worn into the back knife face of the main cutting edge of drill gun helicoid, be applicable to drill gun is carried out sharpening.
