The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
The present invention as shown in Figure 1, a kind of gantry machining center five-face milling head, comprise body of milling head 1, main shaft 2 is found in body of milling head 1 interior installation, it is characterized in that: body of milling head 1 interior sleeping main shaft 22, on the vertical main shaft 2 main shaft bevel gear 3 is installed, main shaft bevel gear 3 is meshed with driven wheel of differential 18, driven wheel of differential 18 connects jackshaft 20, and sleeping main shaft 22 connects driven gear 25, and driven wheel of differential 18 connects driven gear 25.According to described a kind of gantry machining center five-face milling head, it is characterized in that: piston body 28 is installed on the described body of milling head 1, piston body 28 is installed in horizontal axis and forges a knife on the bar 23, and the horizontal axis bar 23 of forging a knife is installed on the sleeping main shaft 22, and spring 29, piston rod 30, piston cap 31 are installed respectively on the piston body 28.
Use principle of the present invention is as shown in Figure 1, 2: a kind of gantry machining center five-face milling head is provided with vertical main shaft 2 and sleeping main shaft 22 in its body of milling head 1; Be connected with main shaft bevel gear 3 on the vertical main shaft 2, be connected jackshaft 20 with the driven wheel of differential 18 of its engagement, jackshaft 20 is connected to driving gear 19, is connected with sleeping main shaft 22 with the driven gear 25 of its engagement; Rotary index device is fixed on the body of milling head 1 for vertical rack sleeve 4, the upper fluted disc 6 of free calibration engagement, lower tooth disk 5 is connected to ram case 8, on the body of milling head 1, piston body 7 is contained on the fluted disc 6, piston ring 9 is contained in the piston body 7, thrust ball bearing 10 is on piston ring 9 tops, bearing nut 11 is connected with vertical main shaft 2 and is pressed on the thrust ball bearing 10, lower gear 12 is installed in the upper end of vertical rack sleeve 4, internal gear 14 is connected on the bearing block 13, bearing block 13 is fixed on the ram case 8, cogging 15 is fixed on the vertical main shaft 2 by shaft coupling 16, cogs 15, lower gear 12 meshes with internal gear 14 simultaneously.The horizontal axis device for loosing knife comprises horizontal axis rear pressing cover 27, piston body 28, piston cap 31, piston rod 30, spring 29, and horizontal axis is forged a knife bar 23 by broaching tool positioning body 26 restriction sites, and the end of this bar of forging a knife connects claw 21.
Application note of the present invention is as follows:
During sleeping main shaft rotary index, piston body 7 top oil-feeds, piston ring 9 moves down, move down by promoting vertical rack sleeve 4, so that the lower tooth disk 5 that is connected on the body of milling head 1 falls, upper lower tooth disk engagement is separated, and the approach switch buting iron 17 on the vertical rack sleeve 4 causes approach switch and sends signal, detect to separate whether to put in place, the whereabouts of vertical main shaft 2 drive by shaft coupling 16 connect cog 15 descend and with internal gear 14 engagements; Separate put in place after, the spindle motor low speed rotation, vertical main shaft 2 rotations drive vertical rack sleeve 4 rotations by 15 engagements with internal gear 14, internal gear 14 and lower gear 12 time that cog, body of milling head 2 is followed and is rotated to set angle; Piston body 7 bottom oil-feeds, move on the piston ring 9, promote to move on thrust ball bearing 10, the bearing nut 11, by moving on the vertical rack sleeve 4 of threaded engagement drive, and drive lower tooth disk 5 and upper fluted disc 6 engagements, be connected to that cogging on the vertical main shaft 2 moved on 15 so that separate with the engagement of internal gear 14, calibration is finished.Only found main shaft 2 when spindle motor rotates again and follow rotation, realize machining.Because the number of teeth of fluted disc is 72 teeth, so body of milling head 1 can realize that differential is 5 ° of precision indexings of totally 72 grades.The accuracy of manufacture of fluted disc has determined the deflection angle indexing accuracy of horizontal axis, therefore will obtain the number of teeth and the precision that higher indexing accuracy only need improve fluted disc.Hydraulic oil enters by the perforate on the piston body 28, and pushing piston bar 30 advances, and spring 29 is subjected to force compresses, piston rod 30 withstands on the horizontal axis bar 23 of forging a knife and makes its reach, and the butterfly spring 24 that horizontal axis is forged a knife on the bar 23 is subjected to force compresses, and claw 21 opens, eject cutter, finish loose cutter action; When the hydraulic oil off-load, butterfly spring 24 resets by spring force, promotes horizontal axis and forges a knife and move behind the bar 24, eject piston rod 30, the forge a knife displacement of bar 23 of horizontal axis rear pressing cover 27 restriction horizontal axis, resetting of spring 29 makes piston rod 30 get back to original position fully simultaneously, finishes the broaching tool action; Reconditioning horizontal axis rear pressing cover 27 can be adjusted top cutter amount.
Structure is provided with sleeping main shaft rotary index device, and horizontal axis has free calibration function, and integral structure need not to increase milling head and just can process workpiece in multi-angle, has saved the time, has improved efficient, has also increased machining accuracy; Horizontal axis is provided with device for loosing knife, does not need to arrive the loose cutter of ad-hoc location ability, therefore assembling interchangeability easy, machine part is good.
