Description
The utility model relates to the lathe drilling tool that is exclusively used in disk cover class such as blue dish of processing method part axial halving hole in a kind of mechanical processing industry.
In the present mechanical industry, when disk cover class part axial halving holes such as processing ring flange, mainly adopt pincers worker line boring method, or the line back is by alignment pin, apotting spindle match-drill.The major defect and the deficiency of this processing method are: (1) precision is low: because precision is to be rule by the workman to guarantee, have artificial error inevitably, the existence of systematic error and random error in addition, mismachining tolerance surpasses ± 0.5mm usually, so be easy to generate waste product.2) production efficiency is low: adopt method of scoring processing, generally will through rule, draw a design, operations such as dotting punch, centering, test drilling, boring, calibration, the common laborer processed 100 pairs of ring flanges in 8 hours at most, and nonproductive to take the lathe time long.3) cost height: because the percent defective height, production efficiency is low, causes single ring flange production cost height.
The purpose of this utility model provides a kind of ring flange of being processed that can guarantee and has the specific drilling tool that degree of precision also can increase substantially the disk cover class part axial halving holes such as processing ring flange of production efficiency.
The purpose of this utility model is achieved in that pressing plate and index dial are from upper and lower surface clamping ring flange workpiece, apotting spindle is inserted in the mesopore of ring flange workpiece and index dial in order to guaranteeing the concentricity of the two, and threaded screw rod is fixed itself and ring flange workpiece in aggregates by nut after passing the mesopore of index dial, apotting spindle and pressing plate.
Circular orientation cover medial surface is a matched in clearance on the B face of index dial and the base, uniform 24 calibration pin-and-holes on the index dial B face circumference.Base circular orientation cover lateral surface has 1 to 3 index pin sleeve, and index pin passes the index pin sleeve and is inserted in the calibration pin-and-hole on the index dial B face.The index pin leading portion has a pin radially, and the stage clip front end is against radially on the pin, and the rear end is pressed in the index pin sleeve by gland.The sector hole that the index pin barrel forward end is no less than the index pin hole depth directly is slightly larger than the index pin diameter, and have two index pin radial column cotter way ditches in this section, the aperture of index pin sleeve back segment is slightly larger than the radially pin length of index pin, pulling back index pin radially rotates it behind the pin releasing slots ditch, radially pin promptly is stuck on the interior step surface of index pin sleeve, and at this moment index dial is free to rotate.
On the table top of base dovetail guide is installed, dovetail guide is made up of upper rail, lower guideway, leading screw and positioning screw.Lower guideway is fixed on the base, has rule above it, has tuning drive gear on the upper rail, the pilot hole frame is installed on the upper rail, on the pilot hole frame drill guide bore is arranged, activity is equipped with the quick change drill bushing in the hole, and rotational lead screw can be adjusted the radial position of boring on the ring flange workpiece.
The utility model can also following manner be realized: have 1 to 3 road oil groove on the B face of index dial, stud with borehole jack in the calibration pin-and-hole.
Index pin pore area on the B face of index dial has tapering, and one section that matches with the calibration pin-and-hole on the index pin is cone.
Stud with the borehole jack of band tapering in the calibration pin-and-hole on the index dial B face, the leading portion of index pin with matching is a cone.
The utlity model has following good effect: 1) use the utility model processing ring flange precision higher.When this drilling tool was made, the quality of fit between setting element was pressed the economic machining accuracy of machine tool and is amplified three times, can guarantee that boring processing time error is no more than ± 0.2mm, improved 2 times than line boring method machining accuracy, can satisfy medium accuracy hole processing request.2) easy to use, the drilling efficiency height.This drilling tool clamps, the calibration fast and flexible, and after base once is fixed on the drilling machine, need not carry out any adjustment, can bore the part of a collection of same specification.This drilling tool adopts axle that workpiece is located in addition, can several ring flange workpiece that stack be holed simultaneously according to the drill bit effective length, can enhance productivity greatly.Adopt this drilling tool, the common laborer can process ring flange in 8 hours more than 1000 pairs, than adopting the method for scoring working (machining) efficiency to improve more than 10 times.3) has certain versatility.By changing apotting spindle, not only can carry out the boring processing of axial 2,3,4,6,8,12,24 halving holes to the ring flange of various sizes, also be applicable to the processing of the disk cover class part axial halving hole that various endoporus precision are higher.4) processing cost reduces significantly.Greatly reduce because saving man-hour and minimizing waste product can cause cost, remarkable in economical benefits improves.
Elaborate below in conjunction with accompanying drawing:
