Abstract
The utility model discloses a cross axle drilling and milling head which is arranged on motor bases in four axial directions of a cross axle. The cross axle drilling and milling head comprises a vertical workbench (2) capable of moving front and back on the motor seats (9), a horizontal workbench (22) capable of moving right and left on the vertical workbench and a transmission case (16) arranged on the horizontal workbench and provided with a driving shaft (5), wherein a cutter head (5) rotating at a high speed is arranged on the driving shaft, and a center driller (13) and a milling cutter (14) are arranged on the cutter head. After the cross axle is located and clamped by the cross axle drilling and milling head, the machining of all four axle end faces and all four axle end face center holes of the cross axle can be achieved by means of one clamping at one station. The cross axle drilling and milling head is compact in structure, reliable to use, not only capable of ensuring the concentricity and perpendicularity dimensional accuracy between the cross axle center holes but also reductive in manufacturing procedures; and therefore production efficiency is greatly improved, manufacturing cost is reduced, and work intensity is lightened.
Description
Technical field
The utility model relates to processing unit (plant), especially relates to a kind of Drilling and milling head that is used to process cross axis faces.
Background technology
As everyone knows, cross axle is a strength member in the automobile differential, and can its quality quality directly has influence on automobile differential realize automobile turning in fast and reliable ground.Therefore; Cross axle not only requires its material that good bending strength and hardness will be arranged; And require between its cross axle axle and the axle very high concentricity and perpendicularity precision are arranged; Guarantee high concentricity and perpendicularity required precision between cross axle axle and the axle, will when four axial center holes of processing cross axle, guarantee concentricity and the perpendicularity dimensional accuracy between its centre bore.At present, machining cross axle axial center hole mostly adopts earlier with location, blank technology hole, four axial end of processing cross axle successively; Divide No. four clampings just can process four centre bores at same station again; Descend finish turning and grinding step processing with the centre bore location again, the processing technology in hole, this spider center has following point: the one; Concentricity between four centre bores of the cross axle that processes and perpendicularity precision are difficult to guarantee; Thereby influence the concentricity and the perpendicularity dimensional accuracy of cross axle, four gear steps operations that cause matching with cross axle are inconsistent, reduce the automobile differential service behaviour; The 2nd,, this processing technology device needs to process a fabrication hole earlier and locatees four axial end of processing cross axle, divides the machining center hole again No. four times, has increased manufacturing procedure, and processing cost is high, and production efficiency is low.
The utility model content
To the existing problem of cross axle processing unit (plant) in the above-mentioned prior art; The utility model provides a kind of concentricity and perpendicularity dimensional accuracy between cross axle axle and the axle of both can having guaranteed; Can improve cross axle processing efficient greatly again; Reduce labor intensity the cross axle Drilling and milling head that cuts down finished cost.
The technical scheme that the technical problem that the utility model will solve is taked is: said cross axle Drilling and milling head is arranged on four axial supports of cross axle; It comprises can be at the vertical workbench that can do to move forward and backward on the support, can on vertical workbench, make the horizontal work level of move left and right and be arranged on the horizontal work level and the transmission case of driving shaft is housed; Said driving shaft is provided with the cutterhead of rotation at a high speed, and said cutterhead is provided with centre drill and milling cutter.
The utility model is because same support is provided with four the vertical each other Drilling and milling heads that also can make front and back and move left and right simultaneously; Cross axle is placed in the middle supporting station locating slot of support; After the clamping, clamping once just can be simultaneously all machines four axial end and four axial end centre bores of cross axle on a station.The utility model compact conformation uses reliably, not only can guarantee concentricity and perpendicularity dimensional accuracy between the hole, spider center, and reduce manufacturing procedure, has improved production efficiency greatly, has reduced processing cost, has alleviated labour intensity.
Description of drawings
Fig. 1 is the sectional structure sketch map of the utility model.
Main motor 2, protective cover 3, drive 4, belt 5, driving shaft 6, driving wheel 7, cross lead screw 8, servomotor 9, support 10, vertically screw mandrel 11, longitudinal rail 12, cross slide way 13, centre drill 14, milling cutter 15, cutterhead 16, transmission case 17, axial end 18, cross axle 19, centre bore 20, supporting station 21, vertically workbench 22, horizontal work level in the drawings, 1.
The specific embodiment
In Fig. 1, cross axle 18 is placed in the cross locating slot of support 9 support platform 20, once compress with pressing plate, on the support of four shaft centre line directions of cross axle, be respectively arranged with four cross axle Drilling and milling heads, said cross axle Drilling and milling head is vertical each other.Fig. 1 is the cross axle Drilling and milling head sectional structure sketch map that expression is arranged on cross axle the right, and support is provided with vertical workbench 21, and vertically being slidingly matched with dovetail groove type longitudinal rail 11 between workbench and the support links to each other; Vertically workbench is provided with vertical screw mandrel 10, when vertically screw mandrel rotates, can drive vertical workbench and on support, move forward and backward (inward-outward direction moves towards the interface); Vertically workbench is provided with horizontal work level 22, and horizontal work level is slidingly matched with dovetail groove type cross slide way 12 with vertical workbench and links to each other, and horizontal work level is provided with cross lead screw 7; When cross lead screw rotates, can drive horizontal work level and vertically make move left and right on the workbench, cross lead screw is driven by servomotor 8 respectively with vertical screw mandrel; On horizontal work level, be set with transmission case 16, be provided with driving shaft 5 in the transmission case, driving shaft one end is equipped with driving wheel 6; Driving wheel links to each other with drive 3 through belt 4, and drive is installed on the main motor 1, and protective cover 2 is housed on belt pulley; Cutterhead 15 is housed on the driving shaft other end, and the cutterhead center is provided with centre drill 13, is arranged at intervals with milling cutter 14 on the cutterhead end face; During work, vertically workbench moves forward (direction in the interface), makes milling cutter cut out axial end 17 from cross axle 18 1 side millings; After having milled axial end, horizontal work level is moved to the left (towards the cross axle direction), makes centre drill on the end face of cross axle, process centre bore 19; Horizontal work level moves right and withdraws from then, and vertically workbench moves backward and withdraws from.Three cross axle Drilling and milling heads on other direction can process other three end faces of cross axle and end face centre bore by the course of work of above-mentioned cross axle Drilling and milling head simultaneously simultaneously.Said cross axle Drilling and milling head all adopts computer to control processing automatically.
