Abstract
A kind of radial drilling machine hole positioning device, the first fairlead is nested with in the middle part of knife bar, the first described fairlead is stepped cylinder, and described first fairlead is fixedly connected with the outer guard circle of the bearing on knife bar, there is gap between the first fairlead inner peripheral surface and knife bar outer circumference surface; Also be arranged with the second fairlead in described knife bar end, the second described fairlead is fixedly connected with knife bar by screw, and described second fairlead used with cutter supporting connection.Technique effect is as follows: by with the first fairlead and manufactured through hole for the positioning datum pair shoulder hole concentric with this through hole is processed, ensure that the concentricity of box parts two concentric holes.
Description
Technical field
The utility model relates to the working position apparatus technical field of intermetallic composite coating, particularly a kind of radial drilling machine hole positioning device.
Background technology
In process of metal working, we are to this clear condition: the production outline of processing work is large, and precision is high, box parts.In box parts exist two concentric holes, and these two concentric holes again in a distance time, general building-block machine cannot meet design and processing request, the especially concentricity of holes.
Now, be generally adopt jig boring machine to process specially, and this kind of processing mode costly, man-hour is long, very uneconomical.
This problem does not also have good solution at present.
Utility model content
For overcoming problems of the prior art, the utility model provides a kind of radial drilling machine hole positioning device, and this device can ensure that the concentricity of box parts concentric holes, structure are simple, and processing cost is low.
The technical scheme in the invention for solving the technical problem is: this kind of radial drilling machine hole positioning device, it is characterized in that: in the middle part of knife bar, be nested with the first fairlead, the first described fairlead is stepped cylinder, described first fairlead is fixedly connected with the outer guard circle of the bearing on knife bar, there is gap between the first fairlead inner peripheral surface and knife bar outer circumference surface; Also be arranged with the second fairlead in described knife bar end, the second described fairlead is fixedly connected with knife bar by screw, and described second fairlead used with cutter supporting connection.
Further, the first described fairlead is removably connected by screw by screw and the outer guard circle of bearing.
Further, the first described fairlead is provided with lubricating cup installing hole, and described lubricating cup installing hole is provided with lubricating cup.
Further, described knife bar can be boring bar, reaming knife bar, fraising knife bar.
Further, the first described fairlead path cylinder axial length dimension is greater than casing wall thickness dimension.
To sum up, the beneficial effect of technique scheme of the present utility model is as follows: by arranging the first fairlead and the second fairlead on boring bar or reaming drilling rod, the drilling rod that reams, first fairlead coordinates fixing left positioning datum with a hole manufactured in two concentric holes, second fairlead and supporting cutter are processed another hole in two concentric holes, ensure that concentricity and the machining accuracy of holes.And this apparatus structure is simple, processing cost is low.
Accompanying drawing explanation
Fig. 1 is the utility model structure chart.
In figure: 1 knife bar, 2 first fairleads, the outer guard circle of 3 bearings, 4 bearings, 5 second fairleads, 6 cutters, 7 lubricating cups, 8 screws, 9 casings, 10 back-up rings, 11 felt collars.
Detailed description of the invention
Be described in detail to characteristic sum principle of the present utility model below in conjunction with accompanying drawing 1, illustrated embodiment, only for explaining the utility model, not limits protection domain of the present utility model with this.
As shown in Figure 1, this kind of radial drilling machine hole positioning device, the first fairlead 2 is equipped with at the middle part of knife bar 1, described first fairlead is stepped cylinder, during use, on casing 9, one of them through hole of two concentric holes processes, and another hole is shoulder hole, and the aperture of described shoulder hole also machines.By knife bar through the holes on described casing 9, one end of the path of the first fairlead 2 is overlapped and inserts in manufactured through hole, and the diameter dimension of path one end excircle diameter of the first fairlead and through hole is suitable.In order to better ensure the position stability between the first fairlead and casing, the first fairlead path cylinder axial length dimension can be designed to be greater than casing wall thickness dimension.When processing the concentric holes in different apertures, the first fairlead of various outer diameter size can be selected.First fairlead leans on the location between outer ladder Planar realization first fairlead of the first fairlead and casing to fix.
Knife bar is provided with bearing 4, is provided with the outer guard circle 3 of bearing, knife bar is also established Packed felt collar 11 and back-up ring 10 outside bearing.First fairlead is fixedly connected with the outer guard circle of described bearing; conveniently process different pore size size concentric holes, can dismountable screw be adopted to be fixedly connected with outer to the first fairlead and bearing guard circle, like this; according to the requirement of different pore size, the first fairlead can be changed at any time.
There is gap between first fairlead inner peripheral surface and knife bar outer circumference surface, make knife bar can in the first fairlead free smooth rotation, complete the processing in hole.
Also overlap in knife bar end and have the second fairlead 5, second fairlead to be fixedly connected with knife bar by dismountable screw 8, the second fairlead and supporting cutter are at shoulder hole place to be processed.By the first fairlead and manufactured through hole as positioning datum processing shoulder hole.
Described knife bar can be boring bar, reaming knife bar, fraising knife bar, after completing a procedure, more can complete subsequent processing by changing knife rod.
First fairlead is provided with lubricating cup installing hole, this lubricating cup installing hole is provided with lubricating cup 7, lubricating cup connects oil feeding device, can realize the oil inlet lubricating to the first fairlead.
By this device, utilize radial drill can complete processing to box parts concentric holes, mustn't use jig boring machine, fully can ensure the concentricity of two concentric holes after processing, the precision of work pieces process is improved significantly.In addition, this apparatus structure is simple, easy to use, reduces generation processing cost, substantially increases productivity ratio.
Above-described embodiment is only the description carried out preferred embodiment of the present utility model; not scope of the present invention is limited; under the prerequisite not departing from the utility model design spirit; relevant technical staff in the field, to various distortion of the present utility model and improvement, all should expand in the determined protection domain of the utility model claims.
