The utility model adopts the double grinding wheels, so the utility model can mill splitting type drill tips and has the advantages of simple structure, high rigidity, easy operation, high repeating sharpening precision and low manufacture cost.
Description
The utility model belongs to machine tool field, particularly a kind of grinding machine that the back knife face and the chisel edge of fluted drill apex point are carried out reconditioning.
In the most of manufacturing enterprises of China, the reconditioning of drill bit is mainly finished by manual at present, and sharpening efficiency is low, is difficult to guarantee the sharpening precision and the quality of drill bit, has seriously hindered the raising of processing throughput.But splitting type apex point drill bit is compared self-centering with common spiral bit, and it is little to have the cutting axial force, and the characteristics that chip removal is good, the life-span is high can greatly improve drilling efficiency, and therefore aircraft and automobile industry abroad widely used.And the reconditioning of existing splitting type apex point is mainly finished by numerical control or automatic drill grinder head abroad.These drill grinder costs are very high, cost an arm and a leg, and a lot of enterprises are difficult to bear.
The purpose of this utility model is to provide that a kind of cost is low, price can be accepted by users, can sharpening high-performance apex point, have the manual splitting type drill point grinding machine of high performance price ratio.
The utility model is made up of lathe bed, planker, guide rail, workbench, retainer, handle, motor, two emery wheels, drill chuck device etc.
Further narrate content of the present utility model below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the vertical view of Fig. 1.
Among the figure, 1 lathe bed, 2Y is to planker, 3 motor cabinets, 4 emery wheels, 5 motors, 6X is to turning handle (being used for adjusting X to planker 12 and the workbench 10X direction motion that is installed on it), 7 handle reverses (can make 180 ° of drill chuck upsets), 8 rotation knobs (can adjust the position of drill bit Z direction), 9 principal shaft locking handles (main shaft piece 18 is locked can not rotate), 10 rotary work-tables, 11 dials, 12X is to planker, 13Y is to turning handle (being used for adjusting the Y direction motion of Y to planker and the motor 5 that is installed on it), 14 table latch handles (rotary work-table 10 is locked can not rotate), 15 drill bits, 16 drill jigs (be used for clamping drill bit), 17 retainers (making drill chuck keep duty), 18 main shaft pieces (spindle end is connected with workbench 10, and the other end is connected with retainer 17 by dovetail groove).
Installed on the lathe bed 1 of the present utility model Y to planker 2 and X to planker 12, motor 5 links to each other with planker 2 by motor cabinet 3, is equipped with two emery wheels 4 on the motor 5; Rotary work-table 10 links to each other to planker 12 with X by dial 11, and the spindle end of main shaft piece 18 is connected with workbench 10, and the other end is connected with retainer 17 by dovetail groove, and the drill chuck 16 that drill bit 15 is housed is connected with retainer 17.
The sharpening of the confidential realization splitting of drill point grinding type apex point at first carries out reconditioning with taper seat mill method to knife face behind two of drill bit, and the common conical surface drill bit after the reconditioning is carried out the reconditioning of splitting type chisel edge again, has promptly finished splitting type drill point grinding.
The drill chuck that fluctuates can make the reconditioning of the drill bit knife face after realizing apex point on a slice emery wheel on the drill chuck device; Turning handle 6 is realized the reconditioning of splitting type chisel edge on another sheet emery wheel.
The double abrasive wheel structure that adopted the utility model realizes the reconditioning of splitting type apex point, makes it have the characteristics of simple in structure, good rigidly, processing ease, repetition sharpening precision height, low cost of manufacture.The splitting type apex point self-centering that institute's sharpening goes out is good, has the cutting characteristics that axial force is little, chip removal good, the life-span is high, can greatly improve drilling efficiency.So the utlity model has wide application prospect.
Embodiment:
As shown in the figure, the drill chuck device 16 that drill bit 15 is housed before the sharpening is installed on the retainer 17 that has dovetail groove, have on the lathe bed 1 Y to planker 2 and X to planker 12, rolling guide under the planker links to each other with handle, X to turning handle 6 drive plankers 12 on rolling guide, be X to straight reciprocating motion, thereby realize the adjustment of drill bit 15 and emery wheel directions X position; Y can drive planker 2 is done Y side on rolling guide straight reciprocating motion to turning handle 13, thereby realizes the adjustment of drill bit 15 and emery wheel Y direction position.X is equipped with rotary work-table 10 on planker 12, the angle of circular cone when the rotation of workbench 10 can be determined to carry out the taper seat drill point grinding.The main shaft of main shaft piece 18 links to each other with workbench 10, loosens principal shaft locking handle 9, and main shaft piece 18 can freely rotate around main shaft.Retainer 17 is slidingly connected by dovetail groove and main shaft piece 18, and rotation knob 8 can be adjusted the position of the drill bit 15Z direction on the retainer 17.When the back knife face to drill bit carried out the taper seat reconditioning, rotation knob 8 was adjusted the distance of cylinder axis and drill axis, so that the relief angle of knife face behind definite institute sharpening drill bit; When the chisel edge to drill bit carried out reconditioning, rotation knob 8 was adjusted the position of the relative emery wheel Z of drill bit direction.When carrying out the taper seat drill point grinding, the angle of adjusting rotary work-table 10 relative dials 11 is to determine the top angle of coning angle and institute's sharpening drill bit, lock table latch handle 14 then, rotation knob 8 is adjusted the distance of cone axis and drill axis, so that the relief angle of knife face behind definite institute sharpening drill bit, loosen main shaft handle 9, grasping drill chuck device 16 swings up and down, thereby realize the rotation of drill bit around main shaft, promptly realize the sharpening of knife face behind the drill bit, ground one after behind the knife face, pull on the retainer 17 handle 7 from top to bottom or from top to bottom, realize the rotation of 180 ° in drill chuck device, carry out the sharpening of another back knife face again.Adjust the stock removal of knife face behind the sharpening apex point therebetween by handle 6.When carrying out splitting type thinning, the angle of adjusting rotary work-table 10 relative dials 11 is to determine the angle of the relative emery wheel transverse plane of drill axis, set lever 14 then, pulling drill chuck 16 makes it rotate around main shaft, thereby determine the luffing angle of the relative emery wheel of drill bit, set lever 9 then, rotation knob 8 is adjusted the position of the relative emery wheel Z of drill bit direction, turning handle 6 feedings realize the reconditioning of half chisel edge, pull then on the retainer 17 handle 7 from top to bottom or from top to bottom, realize the rotation of 180 ° in drill chuck device, carry out the reconditioning of half chisel edge in addition again, thereby realize the reconditioning of splitting type apex point.
