Summary of the invention
The purpose of this utility model will overcome above-mentioned defective exactly, and a kind of numerical control gantry machining center pentahedron milling head is provided.
The technical scheme that the utility model adopted is:
A kind of numerical control gantry machining center pentahedron milling head, its major technique is characterised in that the vertical major in the casing is connected helical gear and bevel gear respectively with horizontal spindle, then be connected with the horizontal transition axle with another helical gear with the bevel gear engagement with another bevel gear of helical gear engagement, the horizontal transition axle is parallel with horizontal spindle; Connect the lower surface fluted disc on the casing, nibble with following end-toothed disc and last end-toothed disc be connected on the oil cylinder protecgulum, piston rod is connected on the casing, piston bush is on piston rod, last clutch is fixed on underpart of the piston rod, then is connected on the vertical drive shaft with the following clutch of last clutches engaged.
The beneficial effects of the utility model are: because milling head is provided with the device of horizontal spindle around vertical major rotation calibration, make horizontal spindle in process, have many machining angles, the usage level main shaft can both be processed in all angles workpiece, because calibration, location, clamping are all carried out under computer control automatically, so can carry out five (and multiaspect) processing to workpiece efficiently, make the lathe work in-process save the time, improve effect, also increased machining accuracy greatly.
Description of drawings
Fig. 1---front view of the present utility model.
Fig. 2---vertical view of the present utility model.
Wherein:
Casing 1, vertical major 2, vertical major are pressed from both sides knife assembly 3, horizontal bevel gear 4, vertical bevel gear 5, big sealing shroud 6, outer seal sleeve 7, oil cylinder protecgulum 8, piston 9, vertical drive shaft 10, are gone up clutch 11, following clutch 12, piston rod 13, upper surface fluted disc 14, lower surface fluted disc 15, horizontal transition axle 16, horizontal spindle 17, helical gear 18, horizontal spindle helical gear 19.
The specific embodiment
As shown in Figure 1 and Figure 2:
A kind of numerical control gantry machining center pentahedron milling head, be provided with vertical major 2 and horizontal spindle 17 in its casing 1, vertical major folder knife assembly 3 is connected with vertical major 2, and vertical bevel gear 5 is installed on the vertical major 2, be connected with horizontal transition axle 16 with the horizontal bevel gear 4 of vertical bevel gear 5 engagements, horizontal transition axle 16 is parallel with horizontal spindle 17, be connected with helical gear 18 on the horizontal transition axle 16, and horizontal spindle helical gear 19 is connected on the horizontal spindle 17; Outer seal sleeve 7 is connected with oil cylinder protecgulum 8, big sealing shroud 6 is enclosed within on the outer seal sleeve 7, be provided with horizontal spindle 17 rotary index devices in the circular hole in it, be upper surface fluted disc 14 and lower surface fluted disc 15, upper surface fluted disc 14 is contained on the oil cylinder protecgulum 8, lower surface fluted disc 15 then is installed on the casing 1 of milling head, the center has piston rod 13 to be connected with casing 1 in the lower surface fluted disc 15, piston 9 is pressed on the piston rod 13, clutch 11 connect to be gone up in piston rod 13 bottoms, is connected with vertical drive shaft 10 with 12 on the following clutch of its engagement.
The driving of vertical major 2 is delivered on the vertical major 2 by vertical drive shaft 10 by the main axle servo motor, realize the rotary cutting purpose of vertical major 2, realize the rotary cutting of horizontal spindle 17 simultaneously by a pair of bevel gear (horizontal bevel gear 4 and vertical bevel gear 5) and a pair of cylindric spiral gear (helical gear 18 and horizontal spindle helical gear 19).
Casing 1 is fixed to cutting head on the lathe by oil cylinder protecgulum 8, and owing to lower surface fluted disc 15 is fixed on the casing 1, and upper surface fluted disc 14 is connected with oil cylinder protecgulum 8.After the start, start working in the machine tool hydraulic station, makes the side milling head be in the precision positioning clamped condition, and cutting head can be carried out various processing to workpiece surface.
The utility model application note is as follows:
When needs carry out the side milling, be located at the clamping cylinder oil-feed on milling head top, piston 9 moves down; Lower surface fluted disc 15 is thrown off, and the last clutch 11 that is contained on the piston rod 13 descends with lower surface fluted disc 15, and with following clutch 12 engagements, casing 1 above coupling part is in stationary state, and casing 1 is in active state.90 ° of rotary switches are installed on outer seal sleeve 7 and unclamp, clamping switch, by the spindle motor low speed rotation, just can drive casing 1 and be rotated motion, the signal that sends by inductive switch and buting iron, the milling head that rotates to the position is sensed signal that switch sends and is made on the piston 9 and move, drive lower surface fluted disc 15 and 14 engagements of upper surface fluted disc on the milling head, be implemented in the postrotational location of milling head and clamp purpose.At this moment, mesh clutch 11 and following clutch 12 originally and be in disengaged condition again in the milling head rotation, can carry out the high-speed milling work of first side this moment.Go round and begin again, the process above repeating can be carried out side processing to second, third face of workpiece etc.Behind the motion touch switch, will automatically perform order.Upper surface fluted disc 14 and lower surface fluted disc 15 can adopt the reasonable number of teeth according to the accurate needs of calibration, and carry out precision indexing by the encoder that is contained on the spindle motor, for example: realize differential is 5 ° of precision indexings of totally 72 grades, and upper surface fluted disc 14 and lower surface fluted disc 15 can adopt 72 teeth.
