Just being offseted when driving microswitch 25 with the chimb of location-plate 27 is advisable.
The utility model solves mesh by the automatic start and stop for realizing feeding of cooperation of power on/off mechanism and electromagnetic clutch
Preceding slipping toothed electromagnetic clutch volume is excessive, which to be difficult to installation, also needs the power transmission of brush 31 and power on/off to be difficult to simplify the reasons such as coordination,
It is more easily implemented main spindle box to move horizontally, chip breaking processing, determine journey cutting, hand feed or quickly move the function such as main shaft 6, specifically
It is as follows：
（1）The moving horizontally on rocker-arm way of main spindle box 1：Handwheel 12 is rotated, through deceleration transmission to the terminal teeth of central shaft 4
Wheel（Engaged with rack）, because rack is fixed under rocker-arm way, so as to drive main spindle box 1 in the enterprising water-filling translation of rocker-arm way
It is dynamic；
（2）Power feed：Handle III19 is pulled to horizontal level, Handle axis 21 drive the roller 30 of the bottom of lever 29 to
Left side, while projection 33 of the position at the top of it touches microswitch 25 makes the powered adhesive of slipping toothed electromagnetic clutch, worm gear it is dynamic
Power feeds main shaft 6 through the drive sleeve 18 of mounting disc 16；When being fed to set depth, wheel shaft 15 is touched by roller 30 with same
Lever 29 is swung to the right, the location-plate 27 being at this moment fixed as one with lever 29 and meanwhile swing and depart from locking ball 35, in extension spring
Under 26 effects, lever 29, location-plate 27, handle III19 are integrally quickly rotated counterclockwise to spacer pin 34, at the same time, convex
The quick rotation of block 33 unclamp microswitch 25 make slipping toothed electromagnetic clutch rapidly power off release and feed-disabling；
（3）Chip breaking is processed：When the material of drilling good toughness（Such as high-alloy steel, stainless steel）When, be difficult to split off such as chip and
It is wrapped on drill bit, not only influences crudy and cutter life, and easily trigger casualty accident, such as uses traditional feeding machine
Structure is processed, then when must in time stop and clear up chip, and use the utility model, only need to pull handle III19 and power off again
Just energy chip breaking, the security of being powered are higher；
（4）Determine journey cutting：Direct rotary dial 2, to dial 2 is locked at into hand with lock-screw 10 after good vernier 3
Complete to determine journey setting on handle seat I11, then handle II14 is promoted, pull handle III19 and can be achieved, adjustment is very convenient, does not have
There is former compound action；The power-off parking immediately after touching wheel shaft 15 and touching roller 30, without impact, without sound, only
There is lift This move in feeding handle to be prompted to operator；
（5）Hand feed or quick mobile main shaft 6：Upper lift handle III19 makes slipping toothed electromagnetic clutch to dotted line position
Power-off, directly pull handle I13 through handle set I11 can drive sleeve 18 realize fast shift spindle 6 or hand feed, handle
I13 setting both eliminates push pull maneuver, will not also occur the stuck inactive phenomenon of handle, and because now roller 30 is right
Pendulum is backed out, and it is also not in touch to stop acting to forget to pull open even if handle II14.
In addition, the more traditional feed mechanism of part of the present utility model reduces 1/3rd or so, material only need cast iron and
Common iron, without any heat treatment requirements, machining also eliminates slotting internal tooth, interior mill and outer mill, not only multiple functional, outside
Type is attractive in appearance, and operates light, and part is not hit power, and assembling maintenance is all very convenient, also simplify production management affairs, although
Outsourcing slipping toothed electromagnetic clutch is wanted, but totle drilling cost declines 18% or so on the contrary.
