Abstract
The utility model relates to a boring combined turning tool, belonging to the technical field of mechanical tools. The utility model is characterized in comprising a carbide bit, a toolbar and a combined toolbar tube; wherein the carbide bit is welded at the toolbar end; the toolbar is arranged inside the combined toolbar tube; a sliding block and a bolt are arranged between the toolbar and the combined toolbar tube for positioning and fixation. The utility model has the advantages that: the structure is simple and reasonable; the production and manufacture are easy, the cost is low; the service performance is good; big, medium and small boring turning tools can be used freely according to the processing requirements; the rigidity in boring processing is good and the positioning precision is high; with multilevel positioning and fixation, the toolbar can be flexed according to the processing requirements of the workpiece, and the length can be fixedly controlled by the sliding block to facilitate the regulation and to improve the processing efficiency and quality of the boring. With the utility model, deep holes of big steps can be processed in a single time without using the tool holder, and the processing range of the machine tool and the cutter is improved.
Description
Technical field
The utility model relates to a kind of metal bore hole lathe tool.Big step deep hole machining combination of features boring tool is especially arranged, belong to the machine tool technical field.
Background technology
At present, common boring tool.A lathe tool can only the very narrow hole of the range of work.The knife bar that has cutter head is installed on the bracing frame, adopts slide block and screw positioning and fixing.Big boring tool can only be processed macropore, if there is the small stair hole workpiece centre then can't processes.And little boring tool rigidity when the processing macropore also can't be processed inadequately.And behind the rotating turret, cutter is reorientated low precision.And the cutter spacing of lathe cutter saddle is limited, once can't adorn a lot of lathe tools.Therefore, existing common boring tool being improved is the important channel of improving bore hole quality and efficient.
Summary of the invention
The purpose of this utility model is exactly the needs according to mechanical bore hole processing, provides a kind of bore hole range of work wide bore hole combination lathe tool easy to use.
The purpose of this utility model is to realize like this, bore hole combination lathe tool is characterized in that being provided with carbide bit, knife bar, combination knife bar pipe, and carbide bit is welded on the knife bar end, knife bar is installed in the combination knife bar pipe, is provided with slide block and screw positioning and fixing between knife bar and the combination knife bar pipe.
Described knife bar and combination knife bar pipe are provided with scale.Described knife bar comprises little boring tool bar, middle boring tool bar and big boring tool bar.Hole boring cutter rod tube and big hole boring cutter rod tube during described combination knife bar pipe comprises, the internal diameter of middle hole boring cutter rod tube is identical with little boring tool shank diameter, the external diameter of middle hole boring cutter rod tube is identical with middle boring tool shank diameter, the internal diameter of big hole boring cutter rod tube is identical with the external diameter of big boring tool shank diameter and middle hole boring cutter rod tube, middle hole boring cutter rod tube is sleeved in the big hole boring cutter rod tube, slide block and screw positioning and fixing between middle hole boring cutter rod tube and the big hole boring cutter rod tube.
The utility model is simple and reasonable, manufactures easily, and cost is low, and serviceability is good.Can arbitrarily use combination big in the lathe tool according to processing request, in, little boring tool.It is narrow to have solved the existing boring tool range of work, reorientates problems such as low precision.This bore hole combination lathe tool can adopt little boring tool bar or middle boring tool bar, big boring tool bar and the combination knife bar pipe coupling that is welded with carbide bit arbitrarily.Little boring tool bar can be installed in the interstitial hole of bracing frame by middle hole boring cutter rod tube and big hole boring cutter rod tube; Middle boring tool bar can be installed in the interstitial hole of bracing frame by big hole boring cutter rod tube; Big boring tool bar can be directly installed in the interstitial hole of bracing frame.Between knife bar and the knife bar pipe, knife bar pipe and knife bar pipe adopt slide block and screw positioning and fixing.The utility model is good rigidly in bore hole processing, and the positioning accuracy height can the big step deep hole of disposable processing, without the rotor frame, improves the range of work of lathe and cutter.Adopt multistage spacing fixing, knife bar can be flexible according to the workpiece processing request, and length can have the fixing control of sliding slider, and is easy to adjust, helps improving bore hole working (machining) efficiency and quality.
Bore hole combination lathe tool also is provided with the elastic opening cover, when processing only needs with dolly knife bar or middle lathe tool bar, can put into the elastic opening cover in the middle of bracing frame, and utilizing screw, fastening that opening is dwindled is fastening.
Description of drawings
Fig. 1 is the structural representation after the utility model assembling;
Fig. 2 is an elastic opening nested structure schematic diagram;
Fig. 3 is a combination knife bar tubular construction schematic diagram of the present utility model;
Among the figure: hole boring cutter rod tube, 7 little boring tool bars in 1 slide block, 2 carbide bits, 3 screws, 4 bracing frames, the 5 big hole boring cutter rod tubes, 6.
The specific embodiment
When bore hole processing only needs with little boring tool bar or middle boring tool bar, can in the middle of bracing frame 4, put into the elastic opening cover, utilize the fastening elastic opening cover opening that makes of screw to dwindle fastening.
