The work process of cutting tool for CNC machine quick-change mechanism of the present utility model is as follows:
First, the push mechanism 11 of translation mechanism, such as cylinder, push pedal 12 can be promoted to move on guide rail 10, thus
Drive rotating drive mechanism, upper and lower drive mechanism, and tool changing parts 1 move at guide rail 10 simultaneously, it is achieved tool changing parts 1 are at cutter
Storehouse 13 and Digit Control Machine Tool blade insert, such as main shaft, between position switching.
Rotating drive mechanism and upper and lower drive mechanism are integrated and do not interfere with each other, wherein the worm screw 3 of rotating drive mechanism
Driving worm gear 2 to rotate, the rotation of worm gear 2 drives conversion sleeve 4 to rotate, owing to pushing part is arranged in conversion sleeve 4, so pushing part
Driven by conversion sleeve 4 and along with conversion sleeve 4 rotates together.Pushing part promotes rotary shaft 6-3 to rotate, and rotary shaft 6-3 drives tool changing
Parts 1 rotate.When needs move up and down tool changing parts 1, jacking parts 5 action of upper and lower drive mechanism, promote transaxle 6 end
The forced section 6-1 in portion rises or falls, thus drives rotary shaft 6-3 to rise or fall, thus realizes the lifting of tool changing parts 1.
Due to worm gear 2 inner hollow, transaxle 6 and worm gear 2 matched in clearance, therefore, moving up and down of transaxle 6 will not be done
Disturb worm gear 2.And worm gear 2 is when driving rotary shaft 6-3 to rotate, due between rotary shaft 6-3 and forced section 6-1 by middle part bearing
6-2 connects, and therefore, jacking parts 5 also will not be caused interference by the rotation of rotary shaft 6-3.
The exchanging knives process of rotating drive mechanism and upper and lower drive mechanism is as follows:
Tool changing parts 1 arrive below tool magazine 13, and the worm gear 2 of rotating drive mechanism rotates, and drive one end of tool changing parts 1 to open
Mouth 1-1 turns to below tool magazine 13, and the cutter 14 of tool magazine 13 bottom is placed exactly in the underface of opening 1-1.Drive machine up and down
The jacking parts 5 of structure do the action risen, and drive tool changing parts 1 to rise, make the cutter 14 of tool magazine 13 bottom snap in tool changing portion
In the opening 1-1 of part 1.Jacking parts 5 do the action declined subsequently, drive tool changing parts 1 to decline, thus by cutter 14 from broach shell
Inside drag down, take out cutter 14.
During dress cutter, tool changing parts 1 arrive below the main shaft of Digit Control Machine Tool, and the worm gear 2 of rotating drive mechanism rotates, and driving is changed
One end open 1-1 of blade insert 1 turns to immediately below main shaft.The jacking parts 5 of drive mechanism do the action risen up and down, drive
Tool changing parts 1 rise, and make the cutter 14 in opening 1-1 snap in main shaft.Jacking parts 5 do the action declined subsequently, and driving is changed
Blade insert 1 declines, and makes cutter 14 stay in main shaft.
Certainly, rotating drive mechanism and upper and lower drive mechanism also concurrently-acting, interference will not be produced each other.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related work people
Member can carry out various change and amendment completely in the range of without departing from this utility model technological thought.This reality
The content being not limited in description by novel technical scope, it is necessary to determine its technology according to right
Property scope.
