The utility model is achieved in that
The utility model arc door face board Milling Process frock, at least two hold-down supports 1 are connected with a pivoting support axle 2, the end hinge of support arm 3 is respectively turned round at pivoting support axle 2 two ends with an equipment, pivoting support axle 2 connects an end of hinge 6 and is hinged with at least two, connect an other end of hinge 6 and be connected with the gate support arm of the member 7 that panel is formed with gate support arm, arc-shaped door body.The gate support arm is connected with at least one upper end that reinforces supporting 9, the lower end that reinforces supporting 9 is connected with frock basis seat 10, the other end of equipment revolution support arm 3 has and moves horizontally the device that milling machine 5 is connected, this end has the jockey of lifting appliance 8, member 7 is connected with station lock 4, and station lock 4 is connected with equipment revolution support arm 3.
Be fixed with the connection rail 12 parallel with pivoting support axle 2 on the equipment revolution support arm 3, move horizontally milling machine 5 and be connected with being connected rail, the center line that moves horizontally milling machine 5 is parallel with the connection rail.
Said hold-down support 1 is three, be connected with frock basis 10 respectively, said equipment revolution support arm 3 is parallel two, the gate support arm 16 of said member 7 is parallel two, is connected with the inner face of same arc-shaped door body 14 by adpting flange 13 respectively, and the outside of arc-shaped door body 14 is connected with panel 15, said station lock 4 is two, be connected with panel 15 respectively, it is two that hinge 6 is propped up in said connection, is connected with gate support arm 16 by flange 17.
The utility model is simple in structure, makes and assembles easily, and with low cost, CNC milling machine is loaded on the frock, serves as the rotation centre of location and benchmark with the pivoting support axle.Moving with lifting appliance, easy to operate as rotation, the working (machining) efficiency height.
The essence that arc door face board milling tool carries out Milling Process is to substitute the processing cambered surface with the some segments of processing with heartstrings.Concrete milling station and milling amount are determined: divide two cuttves to carry out arc door face board Milling Process, roughing station milling depth 3mm, the wide 80mm of milling string, finishing milling station milling depth 1mm, the wide 35mm of milling string.Theory calculates, and with the arc door face board that this frock fine finishining radius of gyration is 10m, its action is 0.100mm, less than 12.5 μ m; Arc door face board radius tolerances after the actual measurement milling
, reached technical requirement on design fully, solved large-scale workpiece circular arc panel processing difficulties, the problem that machining accuracy is not high.
Description of drawings:
Fig. 1 is an overall construction drawing of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is A-A cutaway view of Fig. 1.
Fig. 4 is B-B cutaway view of Fig. 1.
Fig. 5 is for moving horizontally milling machine and equipment revolution support arm johning knot composition.
The specific embodiment:
The utility model by fixing hinge 1, pivoting support axle 2, equipment revolution support arm 3, station lock 4, dedicated leveling move milling machine (its milling head of this equipment rotates adjustable on a vertical plane) 5 jockey, connect a hinge 6, member 7, lifting appliance 8 (be used for dedicated leveling and move milling machine 5, the 3 station adjustment of equipment revolution support arm) jockey, supporting 9 reinforced by workpiece and frock basis 10 is formed.Dedicated leveling moves milling machine and does not belong to the utility model scope, below only describes its mounting means.
Pivoting support axle 2 is hold-down support 1, revolution support arm 3 and connects the rotation centre of location of hinge 6, just a benchmark of deep hole arc door face board milling tool.At first, gate support arm arc-shaped door body joins together with pivoting support axle 2 by connecting a hinge with the member 7 that panel is formed, make the cambered surface of the arc-shaped door panel 15 for the treatment of milling concentric with the pivoting support axle, the members 7 that gate support arm, arc-shaped door body and panel are formed in workpiece reinforcing supporting 9 fixedly secure on the frock basis; Secondly, equipment revolution support arm 3 and 2 assemblings of pivoting support axle, make the revolution support arm around the rotation of pivoting support axle center, with the pivoting support shaft centre line is benchmark, the 5 lathe bed center lines that dedicated leveling moved milling machine on equipment revolution support arm are adjusted to parallel with the pivoting support shaft centre line, adjust dedicated leveling again and move the milling machine milling head, make the pivot center of equipment milling machine milling head vertical with the pivoting support axis; Before Milling Process, the member of forming because of gate support arm arc-shaped door body and panel props up hinge by activity and locatees with the pivoting support axle, so it should be that benchmark carries out disposable accurate adjustment location with the pivoting support shaft centre line that dedicated leveling moves milling machine, reach dedicated leveling and move milling machine and accurately rotate around pivoting support axle center with equipment revolution support arm; When each station milling, need that equipment is turned round support arm and join together securely by station lock, close-fitting shop bolt and attachment bolt and gate support arm arc-shaped door body.The essence that deep hole arc door face board milling tool carries out Milling Process is to substitute the processing cambered surface with the some segment strings of processing.Concrete milling station and milling amount are determined: divide two cuttves to carry out arc door face board Milling Process, roughing station milling depth 3mm, the wide 80mm of milling string, finishing milling station milling depth 1mm, the wide 35mm of milling string.Theory calculates, and with the arc door face board that this frock fine finishining radius of gyration is 10m, its action is 0.100mm, less than 12.5 μ m; Arc door face board radius after the actual measurement milling is
Reached technical requirement on design fully.For further improving the outward appearance of milling face, available hand-held soft band polishing equipment counter plate milling face polishes.Lifting appliance 8 does not belong to the utility model scope, available crane, but position of the present utility model adjustment need be relied on lifting appliance 8 for support.
