Abstract
The invention discloses independent flat capstan, belong to machine tool, including cutter head, tool rest, slide block, pressing plate, it is made up of cylindric fixed body and rotary body and central shaft three part, fixed body is flexibly connected by bearing with central shaft and rotary body, and central shaft is fastenedly connected through fixed body center with rotary body centre bore.Between fixed body and central shaft, by bevel gear to, bevel gear circle, pot wheel form differential attachment connection a rotating body feed screw, band movable slider realizes radial feed.The present invention uses bevel gear and bevel gear circle transmission, coordinates pot wheel pot bar to form differential attachment, realizes radial feed dexterously, is widely used in the processing technology such as grooving of boring and milling machine etc., can increase substantially operating efficiency.
Description
Technical field
The present invention relates to machine tool, particularly facing head.
Background technology
In the lathe work such as existing boring and milling machine, general process is all to realize axial feed by ram telescopic band cutter, and radial feed generally to lean against and to manually adjust cutter on tool rest under Parking situation.It is investigated that the current state-of-the-art method of inquiry is to install special feeding motor powered feeding on tool rest, but owing to tool rest is to rotate, the electric power of motor needs to arrange a carbon brush transmission, and carbon brush is because of long time running friction, it is very easy to damage, it is impossible to ensure electric power normal transmission.
Summary of the invention
In order to solve the machine tooling cutter radial feeding problems such as boring and milling machine, overcoming the defect that the transmission of electric feeding electric power is unstable, the present invention devises a kind of gear-driven feed mechanism.Concrete technical scheme is: independent flat capstan, including cutter head, tool rest, slide block, pressing plate, described independent flat capstan is made up of cylindric fixed body and rotary body and central shaft three part, fixed body is flexibly connected by bearing with central shaft, fixed body is flexibly connected by bearing with rotary body, and central shaft is fastenedly connected through fixed body center with rotary body centre bore；Radially being symmetrical arranged a pair bevel gear in described fixed body, on housing, perforate vertical axial arranges worm screw, mates with worm gear, and worm screw one end connects handle；Central shaft ground floor step arranges bevel gear circle engage with a pair bevel gear on fixed body, being cased with little Double-side umbrella gear ring and worm gear on central shaft second layer step successively, on worm-wheel hub, perforate radial symmetric arranges a pair gap bridge bevel gear and engages with little Double-side umbrella gear ring；Rotary body internal layer is cased with big Double-side umbrella gear ring, simultaneously with the gap bridge bevel gear on worm gear to engaging, the feed gear wheel on feed screw that one side is radially arranged with rotary body engages, equipped with feed nut connection sliding block on feed screw, equipped with tool rest and cutter head on slide block；Described bevel gear circle, the large and small Double-side umbrella gear ring number of teeth is identical.
The handle that described pot bar one end connects can substitute with servomotor, couples with machine tool numerical control system and can realize auto-feed.
The present invention pass a bridge bevel gear use be symmetrical arranged in pairs, the even weighing apparatus of stress can be made, ensure whole differential gear system even running.
In use, the fixed body of independent flat capstan of the present invention is fastenedly connected on machine ram shell, and central shaft is connected with main shaft.When running well, bevel gear circle on central shaft, bevel gear etc. coordinate, and whole gear train produces the output that moves at the uniform velocity the most on year-on-year basis, makes big Double-side umbrella gear ring and rotary body realize constant speed and moves in the same direction, feed gear wheel rotates with rotary body, self keeps geo-stationary to form idle running；During feeding, worm screw drives the gap bridge bevel gear on worm gear and worm gear, makes whole gear train assembly produce differential, big Double-side umbrella gear ring produces differential with the rotary body rotated with central shaft, so that feed gear wheel rotates, drive feed screw action, it is achieved tool feeding.
Advantage of the invention is that employing bevel gear coordinates with bevel gear circle, when running well, make whole gear train produce the output that moves at the uniform velocity the most on year-on-year basis, feed gear wheel forms idle running；During feeding, worm screw drives the gap bridge bevel gear on worm gear, makes whole gear train assembly produce cleverly differential, causes big Double-side umbrella gear ring to produce differential, so that feed gear wheel rotates, it is achieved tool feeding with the rotary body rotated with central shaft.It is widely used in the bore hole of the lathe such as digital-control boring-milling machine, ordinary vertical milling machine, grooving, sphere processing etc., is remarkably improved effect.
