The specific embodiment
The utility model embodiment, as shown in Figure 1 and Figure 2, a kind of machine tool five-face milling head, be provided with upright main shaft 3 and main shaft for sleeping in 21 in its body of milling head 1, be connected with first bevel gear 6 on the upright main shaft 3, be connected with transition axis 4 with the second bevel gear 23 of its engagement, transition axis 4 is connected with first helical gear 25, is connected the main shaft 21 that crouches with the second helical gear 27 of its engagement; Also be provided with the main axis rotation indexing means that crouches on the body of milling head 1.
Described main axis rotation indexing means for sleeping in be body of milling head 1 also be provided with the band keyway middle transmission dividing spindle 20, first end-toothed disc 12, second end-toothed disc 14, dividing head 11, first end-toothed disc 6 light faces fixedly connected with body of milling head 1, second end-toothed disc 14 light faces are fixedlyed connected with square ram 17, and the first end-toothed disc 6 and second end-toothed disc 14 flank of tooth are meshing with each other.
The number of teeth of described first, second end-toothed disc is 144 teeth.
Owing to have upright, two main shafts that crouch, can carry out vertical and horizontal processing respectively; Body of milling head 1 has the function of automatic loading and unloading with after corresponding mechanism connects, and can firmly and exactly be fixed up; The function that has free calibration again makes horizontal axis to process workpiece in various angles; Milling head also has the automated exchanged cutter function of cutter.
Operation principle: the driving of main shaft is delivered on the upright main shaft 3 by the middle transmission dividing spindle 20 on the square ram 17 by the main axle servo motor, and the transmission between the upright main shaft for sleeping in is by a pair of bevel gear (first bevel gear 6 and second bevel gear 23) and a pair of cylindric spiral gear (first helical gear 25 and second helical gear 27) transmission.
On body of milling head 1 side's of being fixed on ram 17, because first end-toothed disc 12 is fastened on the body of milling head 1, on second end-toothed disc 14 side's of being fastened on rams 17, when the main shaft blind rivet 15 on the upright main shaft 3 and four are auxiliary when hanging a blind rivet 16 and being tightened up simultaneously, owing to be fastened on the intermediate sleeve 10, thereby intermediate sleeve 10 makes first end-toothed disc 12 and second end-toothed disc 14 tight engagement make body of milling head 1 precision positioning and body of milling head 1 firmly on the side's of being fixed on ram 17.When body of milling head 1 is carried out automatic unloading operation, middle transmission dividing spindle 20 is at a slow speed behind the spin orientation, earlier with keyway notch alignment position on dividing head on the body of milling head 1 11 and the middle transmission dividing spindle 20, again four upright main shafts being hung a pulling claw 18 unclamps, upright main shaft pull bar 7 in the middle transmission dividing spindle 20 on side's ram 17 moves down, and body of milling head 1 is placed on the support, and upright main shaft pulling claw 19 unclamps, side's ram 17 rises, and body of milling head 1 is removed; The process of installing is just in time opposite with the process that unloads.
When calibration, middle transmission dividing spindle 20 orientations, make dividing head 11 corresponding with the keyway on the middle transmission dividing spindle 20, four auxiliary, and to hang a blind rivet 16 simultaneously released, upright main shaft pulling claw 19 in the middle transmission dividing spindle 20 on side's ram 17 moves down, body of milling head 1 separates with square ram 17, dividing head 11 cooperates with keyway on the middle transmission dividing spindle 20, because dividing head 11 is fixed on the disjunctor cover 8, and disjunctor cover 8 is fixed on the body of milling head 1, so when the spindle motor low speed rotation, just can drive body of milling head 1 and carry out calibration.Because body of milling head 1 is very little with the distance that square ram 17 separates, only be to allow two end-toothed discs throw off mutually, alignment pin on the intermediate sleeve 10 and square ram 17 are not thrown off fully, so intermediate sleeve 10 is not together turned round with body of milling head 1, the position that four upright main shafts hang a pulling claw 18 is still aimed in four auxiliary positions of hanging a blind rivet 16, when calibration finishes, upright main shaft pulling claw 19 in the middle transmission dividing spindle 20 on side's ram 17 is being with body of milling head 1 to move up, after the engagement of two end-toothed discs, four upright main shafts hang a pulling claw 18 and hang tight four auxiliary blind rivets 16 that hang, and the calibration action is finished.Because the number of teeth of end-toothed disc is 144 teeth, so body of milling head 1 can realize that differential is 2.5 ° of precision indexings of totally 144 grades.The accuracy of manufacture of end-toothed disc has determined the deflection angle indexing accuracy of horizontal axis, and indexing accuracy that therefore will be higher just can be accomplished as long as improve the number of teeth of end-toothed disc.
The automatic degree of tightness cutter of upright main shaft 3 is to control by the mechanism on the square ram 17, and the clamping force that four upright main shafts hang a pulling claw 18 and upright main shaft pulling claw 19 is to be provided by the dish spring that is located in each pulling claw chamber, provides and loosen by hydraulic jack.Therefore, we are as long as these hydraulic jacks of control just can be realized the automatic loading and unloading of body of milling head 1.During the loose cutter of upright main shaft 3, the upright main shaft pull bar 7 in the middle transmission dividing spindle 20 is depressed in loose knife oil cylinder action on side's ram 17, is delivered to upright main shaft pulling claw 2 by upright main shaft pulling claw 19, main shaft blind rivet 15, piston 13, pull bar 7, upright main shaft pulling claw 2 moves down and unclamps, and loose cutter is finished.
During the tight cutter of upright main shaft 3, be to realize by the upright main shaft pulling claw 19 in the dish spring tension centre transmission dividing spindle 20.
The tight cutter of main shaft 21 of crouching realizes by the main shaft pulling claw 22 that crouches, the main shaft pull bar 24 that crouches, disk spring 26, leans on the piston rod 28 on the cylinder body 31 to realize during loose cutter.
The left-hand thread technology of floating is adopted in pine cutter action, promptly allows the active force of cylinder body 31 act on earlier on the round nut 30 and transmits, and the bearing of main shaft has been played protective effect.
Five-face milling head makes lathe possess a clamping just can carry out the ability that multiaspect is processed.Both can save the clamping time, can process automatically and continuously again, and make machining accuracy higher.Be applicable to the operation such as curved surface, inclined-plane and boring, tapping, reaming, bore hole of machining shape complexity, be applicable to the manufacturing Multi-varieties and Small-batch Production of aviation, boats and ships, military project and common mechanical.
