The Double-cutter head milling machine
Affiliated technical field
The utility model belongs to the milling machine technical field, is specifically related to a kind of Double-cutter head milling machine.
Background technology
Milling machine is a kind of broad-spectrum lathe, can processing plane (horizontal plane, vertical plane) on milling machine, groove (keyway, T-slot, dovetail groove etc.), minute tooth part (gear, splined shaft, sprocket wheel, helical surface (screw thread, helicla flute) and various curved surface.In addition, also can be used for the processing of revolving body surface, endoporus and carry out cut-out work etc.
Milling machine is generated heat in work, the impact of the factor such as surface smoothness, and the speed of milling cutter feed can not be too fast, and the depth of cut can not be excessive, and when processing parts, milling cutter usually needs back and forth feed more than once just can finish processing to part.In the process of using milling machine, according to the difference of using the milling machine function, often need to change different cutter heads, taken a large amount of time of operator, especially when the same part of processing, change the precision that cutter head also might have influence on part processing.
Summary of the invention
For above problem, the utility model provides a kind of use Double-cutter head simultaneously to part processing, and the depth of cut is large, cuts and mills fireballing Double-cutter head milling machine.
The technical scheme that its technical problem that solves the utility model adopts is: this Double-cutter head milling machine comprises initiatively motor, lathe bed, crossbeam, workbench, transmission device, knife-containing block; Described knife-containing block is loaded on described crossbeam bottom, relatively rotation, and described knife-containing block bottom is designed with main dress cutter holder that can rotation, secondary dress cutter holder, and described main dress cutter holder, secondary dress cutter holder link to each other with transmission device.
As preferably, described Double-cutter head milling machine is designed with over against the nozzle tip of main milling head operating position.
As preferably, described secondary dress cutter holder can break away from transmission device.
The beneficial effects of the utility model are: main dress cutter holder, the secondary dress cutter holder of this Double-cutter head milling machine can assemble cutter head as required simultaneously, part is being cut simultaneously feed when milling, the depth of cut is large, it is fast to cut the speed of milling, can finish simultaneously and rough mill and the finish-milling process process time of greatly having saved part.
Description of drawings
Structural representation when Fig. 1 is this Double-cutter head milling machine crossbeam, workbench, the work of knife-containing block position.
The top view of part when Fig. 2 is main milling cutter, the simultaneously feed of secondary milling cutter.
Fig. 3 is the transmission principle figure that main dress cutter holder, secondary dress cutter holder are worked simultaneously.
Fig. 4 is that secondary dress cutter holder breaks away from transmission device, only has the transmission principle figure of main dress cutter holder work.
The specific embodiment
Below in conjunction with embodiment the utility model is further specified:
Shown in embodiment among Fig. 1, this Double-cutter head milling machine comprises initiatively motor, lathe bed, crossbeam 1, workbench 2, transmission device, knife-containing block 3; Described knife-containing block 3 is loaded on described crossbeam 1 bottom, relatively rotation, and described knife-containing block 3 bottoms are designed with main dress cutter holder 31 that can rotation, secondary dress cutter holder 32, and described main dress cutter holder 31, secondary dress cutter holder 32 link to each other with transmission device 5.The angle that the operator can rotate by regulating knife-containing block 3 is regulated the size that described main dress cutter holder 31, secondary dress cutter holder 32 are staggered, and realizes the adjusting of relative depth of cut size.Part 6 to be processed is fixed on described workbench 2 tops, and the relative knife-containing block of workbench 3 is to left movement.
As shown in Figure 1, the main dress cutter holder 31 of this Double-cutter head milling machine, secondary dress cutter holder 32 have assembled main milling cutter 33, secondary milling cutter 34 simultaneously.As shown in Figure 2, described main milling cutter 33, secondary milling cutter 34 part 6 relatively to be processed stagger relatively, main like this milling cutter 33, simultaneously feed of secondary milling cutter 34, the depth of cut is compared the single cutter head and is greatly improved, it is faster to cut the speed of milling, can finish simultaneously as required and rough mill and the finish-milling process process time of greatly having saved part.
As shown in Figure 1, described Double-cutter head milling machine is designed with over against the nozzle tip 4 of main dress cutter holder 31 operating positions.Described nozzle tip can spray lubricating oil when work, simultaneously main milling cutter 33, secondary milling cutter 34 are lubricated cooling, improves its service life.
Described secondary dress cutter holder 32 can break away from transmission device 5.As shown in Figure 3, the transmission principle figure that main dress cutter holder 31, secondary dress cutter holder 32 are worked simultaneously, this moment, transmission device 5 was with being delivered to simultaneously described main dress cutter holder 31, secondary dress cutter holder 32 by gear structure with power, made it rotarily drive main milling cutter 33, secondary milling cutter 34 is worked simultaneously.As shown in Figure 4, that secondary dress cutter holder 32 breaks away from transmission device 5, the transmission principle figure that only has 31 work of main dress cutter holder, described secondary dress cutter holder 32 can lift relatively together with the gear on it, travelling gear in the middle of breaking away from, at this moment only have main dress cutter holder 31 still to link to each other with described transmission device 5, can work on.
