Description
Technical field
The utility model belongs to machining equipment technical field, is specifically related to the improvement of a kind of boring cutter portion assembling structure.
Background technology
Guide plate seat pitch-row front face 1500 ~ 2300mm in membrane pump lower box, its processing belongs to dark large hole machined, and difficulty of processing is large.As shown in Figure 3, machine tool chief axis 1 is connected with technique boring bar 2 current processing mode, and boring cutter body 6 is fixed by bolt by the end face of technique boring bar 2, is adding support 7 near machine tool chief axis 1 end to technique boring bar 2; Therefore, technique boring bar 2 and boring cutter body 6 are cantilever structure, and under the effect from gravity, technique boring bar 2 front end lets droop, and easily increase processing Form and position error; With bolts between boring cutter body 6 and technique boring bar 2, need perforate on technique boring bar 2, reduce technique boring bar 2 intensity, thus have impact on machining accuracy further.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of structure simple, the boring cutter portion dress that machining accuracy is high.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises machine tool chief axis, machine tool chief axis is provided with technique boring bar, it is characterized in that: the end of described technique boring bar is provided with bracing or strutting arrangement, described technique boring bar is provided with boring cutter body between bracing or strutting arrangement and machine tool chief axis; Described boring cutter body is made up of two halves cutter hub, and the side that described half cutter hub is relative is provided with the semi-circular groove coordinated with technique boring bar; Be connected by connecting bolt between two halves cutter hub; After described two halves cutter hub is combined integrated, the aperture that two halves circular trough is formed is less than the diameter of technique boring bar.
The beneficial effects of the utility model.
1, the utility model is matched with technique boring bar by the semi-circular groove between two halves cutter hub; Adopt the mode of frictional force boring cutter body and technique boring bar to be fixed, without the need to processing screw hole on technique boring bar, the intensity of technique boring bar is guaranteed, thus when ensure that lower box guide plate bore expands, the intensity of technique boring bar and machining accuracy.
2, the utility model boring cutter body is arranged at the middle part of technique boring bar, and arranges support at the end of technique boring bar, makes technique boring bar no longer and is cantilever design, therefore, can not produces sagging because of deadweight, thus ensure that machining accuracy, improve product quality.
3, the utility model structure is simple, and production and processing is convenient, with low cost, also has certain protective effect to lathe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of boring cutter body.
Fig. 3 is the machining sketch chart of existing boring cutter portion dress to lower box.
In accompanying drawing 1 for machine tool chief axis, 2 for technique boring bar, 3 for boring cutter body, 4 for bracing or strutting arrangement, 5 for lower box, 6 for boring cutter body of the prior art, 7 for support of the prior art, 8 for cutter head, 9 for clamping screw, 10 for balladeur train, 11 for chute, 12 for connecting bolt, 13 for semi-circular groove, 14 be half cutter hub.
Detailed description of the invention
The utility model comprises machine tool chief axis 1, machine tool chief axis 1 is provided with technique boring bar 2, it is characterized in that: the end of described technique boring bar 2 is provided with bracing or strutting arrangement 4, and described technique boring bar 2 is provided with boring cutter body 3 between bracing or strutting arrangement 4 and machine tool chief axis 1; Described boring cutter body 3 is made up of two halves cutter hub 14, and the side that described half cutter hub 14 is relative is provided with the semi-circular groove 13 coordinated with technique boring bar 2; Be connected by connecting bolt 12 between two halves cutter hub 14; After described two halves cutter hub 14 is combined integrated, the aperture that two halves circular trough 13 is formed is less than the diameter of technique boring bar 2.
The end of described half cutter hub 14 is provided with chute 11, and described chute 11 is provided with balladeur train 10 by clamping screw 9, is provided with cutter head 8 between described balladeur train 10 and chute 11.Coordinated by balladeur train 10 and chute 11, the position of adjustable cutter head 8, thus realize the processing to different size endoporus.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
