Description
Technical field
The invention belongs to the machining apparatus technical field, relate to sharpening machine, especially relate to a kind of multi-functional cutter grinding machine.
Background technology
In part processing, the processing of boring and the processing of screw thread are the most general.The prerequisite of screw thread processing is to carry out first the drilling processing of bottom outlet.End mill(ing) cutter can be used for the hole of various shapes on milling groove and the part, step surface, side, external curve surface and various cams etc., and the plane surface after its processing is smooth.Screw tap is for the processing that is threaded.Cutter can produce wearing and tearing after using a period of time, and working (machining) efficiency reduces.At present a lot of cutters are just discarded afterwards or are carried out reconditioning in damage.Hand grinding is had relatively high expectations to workman's technical merit, and the quality of simultaneously reconditioning is also unstable.
For this reason, people have carried out long-term exploration, have proposed various equipment that can single certain cutter of reparation, but not with the integrated equipment of multiple cutter grinding function.For example, Chinese patent literature discloses a kind of sharpening machine [application number: CN200920014738.8], comprises support, cover body, motor, emery wheel, drill bit reconditioning seat, drill bit back angle reconditioning seat, drill positioning device and drill bushing; It is characterized in that: described drill bushing is configured to by taper sheath, intermediate plate, retainer, knob and Elastic Steel; Described drill positioning device is made of positioning seat, button, block and elastic clip.This abrasive drilling function is carried out reconditioning to spiral bit.But the somebody has invented the multi-type tap grinding machine [application number: CN200510061284.6] of the old screw tap of a kind of reconditioning different model, it comprises lathe bed and the track which is provided with, the linking arm that is connected with on the slide unit, the handle that links to each other with linking arm and connector, and grinding wheel drive mitor, it is characterized in that: be connected with lever arm on the described connector.
Although such scheme has improved the reconditioning performance to a certain extent, still can't finish the reconditioning to the variety classes cutter.On the other hand, screw tap divides by thread rotary orientation, can be divided into right hand thread tap and left-hand thread tap, and wherein right hand thread tap is the most general, and left-hand thread tap is used for processing left hand thread, and product will be used for special occasions, and consumption is less.Existing small-sized screw tap sharpening machine generally only can the reconditioning right hand thread tap.In addition, the end reconditioning of end mill(ing) cutter mainly is anterior angle, relief angle, the front clearance of reconditioning milling cutter, and is slightly different for the form of its reconditioning rear knife edge of end mill(ing) cutter of 2 swords, 3 swords, 4 swords.At present common reconditioning with 3 swords, 4 blade milling cutters is divided into two different grinding holes and grinds.
