During work, floor installation links together the T-shaped groove of cutter and tool grinding machine slide plate and base by T-shaped key, then uses bolted on plane on the slide plate of general tool grinding machine.The specific works process is as follows: the drill gun that will treat sharpening is inserted in rack sleeve, and makes the V-arrangement face of the carbide alloy V-shaped groove applying V-arrangement locating piece partly of drill gun.Then tighten the drill gun housing screw, make the V-arrangement face of latch segment compress the arc surface of the carbide alloy of drill gun, thus drill gun is fixed.Determine the horizontal level of a face of V-arrangement locating piece by the horizontal groove of rack sleeve lateral wall.Set the horizontal level of drill gun inner edge by the spindle index dish of sleeve bearing front end.Unclamp interior exterior angle set lever, rack sleeve is rotated around the second rotating shaft, rely on inside and outside horn craving scale to adjust its anglec of rotation.Unclamp the relief angle set lever, rack sleeve is rotated around the first rotating shaft, rely on the relief angle dial to adjust its anglec of rotation.The swivel feeding handwheel can make rack sleeve around its axis rotation, relies on the spindle index dish to adjust its anglec of rotation.Select suitable half slot on carriage, and carriage is moved to suitable position on pressure pin, hold the drill gun shank.By above-mentioned adjustment, namely complete 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, and after relief angle is transferred to required angle, locking relief angle set lever.At first grinding interior angle, the stock removal at exterior angle can be reduced in the exterior angle of then regrinding, and easily judges the end point of helicoid.During the grinding interior angle, unclamp interior exterior angle set lever, hold the feeding handwheel, the oscillating spindle sleeve transfers to required angle with interior angle, exterior angle set lever in locking.Then unclamp straight pin, make the disengagement that is connected of cam and rack sleeve, hold the feeding handwheel, make the rack sleeve revolution, the horizontal groove on rack sleeve is alignd with the zero-bit of spindle index dish, be horizontal thereby the drill gun outside is transferred to.Then lock the rack sleeve lock-screw, the slide plate of reciprocating sliding cutter and tool grinding machine allows the drill gun inner edge move back and forth in the scope greater than grinding wheel width, and the cross slide of feeding cutter and tool grinding machine makes the drill gun inner edge progressively near emery wheel.Until grinding goes out suitable inner edge.After the interior angle grinding is complete, make drill gun leave the emery wheel certain distance, unclamp interior exterior angle set lever, hold the feeding handwheel, the exterior angle is set on the required number of degrees, then exterior angle set lever in locking.Because the spiral relief angle of the drill gun outside helix by cam generates, so the elevation angle of drill gun relief angle and inside and outside horn craving scale is irrelevant, 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 relative fixing with the rack sleeve position, rotation and feeding together.Holding the feeding handwheel, drill gun outside groove plane is adjusted on horizontal level, is also the starting point of helicoid.According to the difference of boring material, select suitable cam ring, push-and-pull roller gear level rests on selected cam ring roller.Unclamp the rack sleeve lock-screw, rack sleeve can freely be rotated and play.Hold the feeding handwheel, promote forward rack sleeve, 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, make within the whole length of drill gun outside is in the abrasive wheel end face ring width.In 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 gapless 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 turns over approximately 120 to positive direction
, just can finish helix, then rotate to negative direction (pushing away forward simultaneously).So repeatedly, and constantly rotate the feeding handwheel to negative direction, drill gun is constantly moved to the abrasive wheel end face 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 being transferred to required angle, main shaft goes to+and 55
, coming to grinding oil clearance relief angle by reciprocating motion and the traverse feed of cutter and tool grinding machine longitudinal slide, after oil clearance, the intersection of angle plane and interior angle plane just in time passes through the end point of drill gun V-type groove.Based on said process, cutter sharpening device of gun drill of the present invention has been realized the rear knife face of the main cutting edge of drill gun is worn into helicoid, has thoroughly solved thus existing cutter sharpening device of gun drill and the rear knife face of the main cutting edge of drill gun can't have been worn into the problem of helicoid.
