Description
Technical field
The utility model is related to a kind of general manual floating centering device of screw thread process when being widely used in hand tapping.
Background technology
Tap holder is that a kind of Do-All for clamping taper shank, straight handle tools and clamping screw tap is attached in multi-purpose fixture series.It is to ensure that axiality requires that, typically using the top centre bore tapping for withstanding screw tap, or using fixed tap chuck, above two method all not enough facilitates on lathe during machining internal thread.In the manufacturing, aperture tapping is always disquieting work.Main cause is nothing but that screw tap is difficult and thread Pilot hole precision centering, slightly deviation or careless, and screw tap just fractures in bottom outlet, and workload has both been increased for no reason, and product quality is substantially reduced again.At present, in machining, manual tapping still occupies certain status, because in actual production, Jing is commonly encountered some screwed holes due to the restriction of position or part shape, screw tap is held in handle of a knife, not with float function.It is not suitable for machine tapping, so manual tapping must be adopted, while minor thread hole diameter is less, the intensity of screw tap is relatively low, easily snaps off during machine tapping, typically commonly uses manual tapping yet.But manual tapping there is also many problems really, it is desirable to which workpiece just will be needed the one side of tapping to be placed in position horizontally or vertically by processed clamping workpiece, when starting tapping, screw tap is put just, the axis direction of screw tap is then pushed down with proficiency, with another hand tap wrench is gently rotated.Rotate tap wrench when, two hands of operator firmly will be balanced, it is not possible to be overexerted and double swerve, otherwise easily by form of thread tear and cause screwed hole expand and there is taper, during tapping, feel very laborious.Can not stir tap wrench to screw out screw tap with a quick-moving speed, if screwing out screw tap with tap wrench, easily produce and wave and shake, so as to destroy the surface roughness of screw thread.Correct tapping method is only taken, the crudy of manual tapping is just can guarantee that.In horizontal processing, the weight on common floating clamp is easy to make skew duplicate to the center line of rotary shaft.
The content of the invention
The purpose of this utility model be in view of the shortcomings of the prior art part, there is provided it is a kind of efficiently, flexibly, tapping part crudy can be improved, production cost is reduced, improve the tapping assistant device of working (machining) efficiency, tapping, use, manual float centrih chasing bar easy to adjust are especially carried out to different workpiece.
For achieving the above object, a kind of manual float centrih chasing bar that the utility model is provided, including：The column 6 on base 7 is vertically connected firmly, the vertical tube 5 in the column 6 is coaxially connected firmly, and row is assemblied in the connection cantilever 12 of the vertical tube 5, and the work holder 13 in the plane of base 7 in the plane of base 7, it is characterised in that：In the free end of the connection cantilever 12, screw tap is set to produce the tapping tracking mechanism 11 of axial pressure when being provided with hand tapping, and be provided with the cylinder of tapping tracking mechanism 11 vertically downward tapping centering top 10, work holder 13 is fixed in the table plane of floating disc 9, is fixed on retaining mechanism 8 of the central shaft of floating disc 9 by the panel connection of base 7 below the panel.
The utility model has the advantages that compared to prior art.
1st, compact conformation.The utility model presses the operating space size of operator's real work, design long 500 millimeters, it is wide 400 millimeters, it is high 730 millimeters, by vertically connecting firmly the column 6 on base, coaxially connect firmly the vertical tube 5 in column 6, with the floating disc 7 for floating on susceptor surface, it is assemblied in the connection cantilever 12 of the vertical tube 5, and the composition work-piece tapping device of work holder 13 in the plane of base 7, compact conformation.Different operating place can be flexibly placed in, be very suitable for operator carries out hand tapping to workpiece, during tapping, by regulation handle disk 1, adjust the upper-lower position of tapping tracking mechanism 11, reach suitable tapping distance during tapping.
2nd, efficiently, flexibly.The utility model is in the free end of the connection cantilever 12, screw tap is set to produce the tapping tracking mechanism 11 of axial pressure when hand tapping is set, cooperation can dispose the floating disc 9 of the general clamping tool for being suitable for different workpieces, can be in tapping, float centrih, treats that tapping workpiece under floating disc 9 and item point or the effect of centering pin, is easily moved on base X, Y plane, locked, after tapping processing, it is consistent that form of thread axial line is able to coincidence with thread Pilot hole axial line.It is locked under the collective effect up and down of retaining mechanism 8 and floating disc 9, fixed workpiece carries out operation.During manual tapping, can continuously adjust between self-centering and variation amount of floating, it is unrestricted to floating action.Tapping cut tapping while, screw tap synchro-feed in the presence of the vertical pretightning force of tapping tracking mechanism 11；By different clamping modes, the tapping requirement to different size, different shape part is reached.
3rd, tapping part crudy can be improved, production cost is reduced, working (machining) efficiency is improved.The utility model is by with adjustable self-centering action floating disc 9, coordinate the tapping centering top 10 vertically downward arranged in the cylinder of tapping tracking mechanism 11, with the work holder 13 for being fixed on floating disc 9, remain can the screwed hole center that be threaded workpiece to overlap with the center line of screw tap, a reliable and stable floating job state is formed during tapping, thread Pilot hole behind floating direction is always coaxial with the rotary shaft axial line of screw tap, and it can be clockwise or counterclockwise to rotate, the characteristics of self centering, causes tapping to obtain accurately positioning very much, so as to improve the working (machining) efficiency and crudy of tapping part, reduce production cost, and can prevent from being threaded workpiece generation chatter mark, extend the life-span.
