Abstract
The utility model relates to an auxiliary device of boring lathe long hole machining. The auxiliary device of the boring lathe long hole machining comprises supporting frames which are connected with a boring lathe working table, through holes used by boring bars to pass through are formed in the supporting frames, gaskets are arranged on the bottoms of the supporting frames, and the supporting frames are connected with the working table through screws. The auxiliary device of the boring lathe long hole machining comprises two supporting frames with centers of the through hole being corresponding to each other, supporting sleeves are arranged inside the through holes, the boring bars pass through the through holes, and the supporting sleeves enable the boring bars to rotate and stretch out and draw back more freely. The auxiliary device of the boring lathe long hole machining is fixed on the head portion and tail portion of a long hole, the through hole centers of the two supporting frames are concentric with main shafts of the boring bars, so that machining decentration and machining vibration caused by boring bar dead weight are avoided, machining accuracy of long hole machining is improved, and greater effects are made to the protection of boring lathe accuracy.
Description
Technical field
The utility model belongs to the machine tooling field, is specifically related to a kind of boring machine deep and long hole auxiliary processing device.
Background technology
It is that the hole total length is very large with the ratio in aperture that Deep-Hole Drilling Technology generally refers to process draw ratio, thereby is general utility tool, not competent special process, instrument and the equipment that must adopt of lathe.In mechanical manufacturing field, deep hole machining is a difficult problem in machining, for parts in small batch processing, do not having under the special equipment of deep hole machining, traditional handicraft mainly adopts the direct bore hole of lathe, adopt cantilever design man-hour owing to adding, boring bar is under action of gravitation, and the front end of boring bar lets droop, and makes hole after processing that diameter can occur and becomes large, the phenomenons such as taper appear, thus the requirement that does not reach crudy.
Summary of the invention
In view of this, the utility model provides a kind of boring machine deep and long hole auxiliary processing device, has overcome above-mentioned weak point, and is simple in structure, improved machining accuracy.
The utility model discloses a kind of boring machine deep and long hole auxiliary processing device, comprise the bracing frame that is connected with boring table, support frame as described above has the through hole that boring bar is passed.
Further, support frame as described above bottom is provided with pad, and bracing frame is connected with the boring table bolt.
Further, support frame as described above is two, and two bracing frame through holes are concentric.
Further, be provided with support set in described through hole.
The beneficial effects of the utility model are: boring machine deep and long hole auxiliary processing device of the present utility model; boring bar passes from through hole; support set in through hole rotates boring bar and stretches more freely in through hole; as required the utility model is fixed on head and the afterbody of deep hole; make two end supports frame through hole center concentric with spindle of boring bar; avoided the processing bias that causes due to the boring bar deadweight and vibrated, having improved the machining accuracy of deep hole machining, also protection boring machine precision having been had larger effect simultaneously.
Description of drawings
For the purpose, technical scheme and the advantage that make utility model is clearer, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is front view of the present utility model;
Fig. 2 is scheme of installation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in the figure, a kind of boring machine deep and long hole auxiliary processing device comprises the bracing frame 1 that is connected with boring table 9, and support frame as described above 1 has the through hole 2 that boring bar 6 is passed.
In the present embodiment, support frame as described above 1 bottom is provided with pad 4, and bracing frame 1 is connected with boring table 9 bolts.
In the present embodiment, support frame as described above 1 is two, and two bracing frame through holes 2 are concentric.
In the present embodiment, be provided with support set 3 in described through hole.
the utility model boring machine deep and long hole auxiliary processing device, bracing frame 1 is placed in the two ends of wanting processing parts 7 lead to the hole site, adjust the pad 4 of bracing frame 1 bottom, make two end supports frame through hole 2 centers, boring bar 6 centers and part 7 machining hole centres, by bolt 5, bracing frame 1 is fixed on workbench 9, boring bar 6 passes bracing frame through hole 2 and part 7 machining holes, boring cutter 8 is installed to be processed to the center from part 7 two ends, support set 3 is installed in bracing frame through hole 2, support set 3 surfaces scribble lubricant grease, to reduce the friction of support set 3 and boring bar 6, maintenance for convenience detach, bracing frame 1 is supported boring bar 6 at the two ends of part 7 machining holes, avoided the processing bias that causes due to boring bar 6 deadweights and vibrated, improved the machining accuracy of deep hole machining, also protection boring machine precision there is larger effect simultaneously.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and not depart from the spirit and scope of the present utility model that appended claims limits.
