Description
Technical field
The present invention relates to a kind of Digit Control Machine Tool, specifically a kind of being used for to various tricuspid solid center bits and cotter mill cutter, slotting cutter and the chamfering device etc. of the shape numerical control three-tip carpenter's drill tapping machine that carries out opening processing partly.
Background technology
Along with machining accuracy require more and more higher, various machining tools are also had higher requirement, at present carpenter opening processing is mainly contained following three kinds of methods: first kind be operating personnel with handing directly grinding on emery wheel 2 of drill bit 1, adopt manual feeding, see Fig. 1; Second kind is that fixed position before emery wheel 2 is provided with guide pin bushing 3, and drill bit 1 is stretched in the guide pin bushing 3, adopts manual feeding method again, sees Fig. 2; The third is to set up index pin 4 and clamping screw 5 on the basis of original guide pin bushing, and guide pin bushing 3 is arranged on movably location on the cross saddle 6, although this mode has the location, but owing to remain manual operation, the feeding speed can not be consistent with length with emery wheel time of contact, the error that grinds is very big, and the control that end tooth is beated is all〉0.3mm.And in the existing processing mode, the people is at the emery wheel front-operated, through regular meeting sand grains takes place and collapses the into phenomenon of eyes, breaks if too firmly cause emery wheel during feeding, also can produce security incident.Therefore, all there is low precision in the mode of at present the carpenter opening being processed, the shortcoming of poor stability.
Summary of the invention
In order to overcome the problem that prior art exists, the purpose of this invention is to provide a kind of numerical control drill tapping machine, this numerical control drill tapping machine can to various tricuspid solid center bits and cotter mill cutter, slotting cutter and partly the chamfering device etc. of shape carry out opening processing, and machining accuracy height, efficient height; Security is good, easy to operate.
The objective of the invention is to be achieved through the following technical solutions:
A kind of numerical control drill tapping machine is characterized in that: it comprises frame, emery wheel, clamping device, feed arrangement, grinding wheel shape trimming device and controller; Emery wheel and feed arrangement are installed on the frame; Being used for the emery wheel of coping drills is connected with the emery wheel drive motors; Clamping device is arranged on the feed arrangement, and clamping device comprises chuck, dividing head and clamping cylinder, the chuck that is used for fixing drill bit and the dividing head that is used for controlling the drill bit angle all with clamp cylinder and be connected; Feed arrangement be connected with the feeding motor and can near or away from emery wheel; Clamping device is with feed arrangement and be used for the grinding wheel shape trimming device that emery wheel is repaired all is connected with controller.
For making the drill bit fixation, accurately locate for drill bit, among the present invention, before chuck, be provided with locator and stabilizer.Be provided with stable piece in stabilizer.On clamping device, be provided with the adjuster that is used for adjusting the drill bit angle.
For guaranteeing the accurate of the drill bit amount of feeding, described feeding motor is accurate segmentation stepper motor.
Among the present invention, the grinding wheel shape trimming device is made up of one group three finishing pens, finishing pen is arranged on opening surface and two sides of emery wheel, and is installed on the guide rail on the feed arrangement and with controller and is connected, along with the wearing and tearing meeting of emery wheel and grinding workpiece synchroballistic together.
Feed arrangement of the present invention is realized abrasion of grinding wheel is compensated automatically by controller.
With traditional hatch method ratio, the present invention has the following advantages:
1, the present invention adopts the feeding of accurate segmentation stepper motor, and two or more end points can be beated is controlled at≤0.03mm, and the error that grinds is little.Existing three kinds of methods adopt manual feeding, because the hand feed speed can not be consistent with length with emery wheel time of contact, the error that grinds is very big, and the control that end tooth is beated is all〉0.3mm.
2, the present invention repair the pen all be contained on the guide rail, can guarantee that the finishing shape of emery wheel is in full accord; The order first three methods is repaiied grinding wheel shape by manual, can not guarantee the uniformity of each finishing.
3, among the present invention, finishing pen is by computer control, along with the wearing and tearing meeting of emery wheel and grinding workpiece synchroballistic together, when repairing emery wheel at every turn finishing pen and grinding workpiece with the contact point of emery wheel all in the place of debugging at first; When three kinds of present methods are repaiied emery wheel, even the finishing guide rail is housed, can not solve stationary problem, repair emery wheel at every turn and all will adjust for a long time, the dress guide rail does not have actual use value.
4, calibration of the present invention adopts accurate segmentation stepper motor drive worm gear snail pole to realize, can tell multiple angles arbitrarily, precision can be controlled in 0.1 degree, cutting edge calibration on circumference of a lot of workpiece, because of reasons such as process equipment and debugging, do not reach the requirement of drawing, such as two-edged should be to differ 180 degree, three swords be 120 the degree, four swords be 90 the degree, but error is arranged after working it out, and the quick method that this situation is traditional can not carry out calibration fast and accurately to workpiece, and that the present invention can do is faster and better; Existing three kinds of modes are fully with each operative employee's the calibration of feeling, weak effect, although wherein the third method can be adorned index dial, it can not be revised at the actual error of workpiece.
5, the present invention is not owing to need operating personnel directly to go reconditioning, and operating personnel stand in the side operation, even the unexpected thing of emery wheel unexpected explosion when rotating at a high speed takes place, also can not hurt the operative employee, and security is good.
6, inventor's high efficiency labour intensity is low, and each operating personnel can operate 2-3 platform equipment, and it all is automatic clamping the feeding finishing; Existing three kinds of method one people can only operate one, and it is big to consume a lot of physical labor intensities.
7, the present invention is easy to operate, and critical step is gone to guarantee that general new hand learns a week and can skillfully operate fully by computer and special tool anchor clamps; And generally taking 1 year, existing three kinds of methods just can reach skilled degree later.
The present invention is a kind of high accuracy, efficient, safe, laborsaving, easy-operating Digit Control Machine Tool, is applicable to the opening processing of various solid center bits.
