Description
Technical field
The present invention relates to a kind of instrument of attacking the system screw thread, particularly a kind of tapping lever apparatus with adjustment function.
Background technology
Usually will carry out the tapping operation to the bottom outlet after the boring in the machining operation, former tapping is generally the manual tapping of manpower; Though can accomplish the tapping operation, time-consuming, effort, and also tapping quality is poor; Percent defective can not satisfy efficient, the high-quality demand of tapping operation also than higher.
The existing tapping device of comparatively popularizing is a rocking arm drilling-tapping machine, and its mode of production is that the tapping machine is only attacked a screw thread at every turn, and the staff needs repeatedly mobile product of repeatability when a plurality of teeth of processing hole, carries out tapping processing repeatedly.This tapping machine can be accomplished the tapping operation more efficiently, and more manual tapping has been than also having improved production efficiency accordingly, raises the efficiency the demand with tapping quality but this tapping machine can only satisfy the single hole tapping; Because need repeatedly processing; Leak the phenomenon of attacking so screw thread occurs through regular meeting, thus the problem that causes fraction defective to rise, in addition; If the bottom outlet position after the boring has dislocation slightly, will influence the precision of tapping.
Along with expanding economy, a kind of bull tapping machine once appearred on the market, drive the tooth attacking device rotation during work of bull tapping machine; Again the screw tap of a plurality of tapping bar clampings on the tooth attacking device is aimed at and headed in the ready made bottom outlet, just become screw on the hole wall of bottom outlet by tap out, but this tapping machine tooth hole of position, a plurality of hole of tapping once; Production efficiency is high, but the tapping bar inside of this tapping machine does not have automatic mechanism, can't control separately; Be engaged in when carrying out the synchronous tapping of a plurality of bottom outlets on the tooth attacking device multi-shaft device, when the tapping machine drives that a plurality of tapping bars carry out tapping work on the tooth attacking device, after the screw tap on the tapping bar is just changeing incision simultaneously; Because the spiral edge of a knife of workpiece and screw tap; The cause that residing angle is different separately causes during work and does not advance tooth simultaneously, and the bottom outlet degree of depth of workpiece is not quite consistent; Counter-rotating is withdrawed from the time of can not be softer; The phenomenon that causes random tooth, sliding tooth or indivedual screw tap to fracture, percent defective is high, can not satisfy modernization industry and produce tapping work production high efficiency, high-quality demand.
Summary of the invention
Therefore; To above-mentioned problem; The present invention proposes a kind of reasonable in design, precision height, flexible operation, tapping good stability; Can be followed the trail of the aperture function automatically by control separately, the tapping lever apparatus that makes the tapping machine once attack a plurality of apertures simultaneously when being used with adjustment function with bull tapping machine.
For solving this technical problem; The present invention takes following scheme: a kind of tapping lever apparatus with adjustment function; Comprise tapping body, drive link, tapping awl; One end inside circumference wall upper edge axial component of said tapping body offers the chute of indent, and an axial end of said drive link is provided with the opening cavity volume, and that end embedding in axial sliding that said drive link has the opening cavity volume is through on the chute of tapping body indent; Removable being fixedly arranged on the free end of tapping body away from drive link of said tapping awl; Said drive link wears a straight pin away from the periphery of the corresponding opening cavity volume of that end of tapping awl, and said tapping body also wears a straight pin near that end periphery of tapping awl, is provided with flexible member between said two straight pins.
Further improvedly be: the Plug Division cross section that said drive link cooperates with the tapping body is a polygon; Offer the polygon chute of the indent that is complementary with drive link Plug Division cross section on the said tapping body inside circumference wall, the embedding in axial sliding of said drive link is through on the polygon chute of tapping body indent.
Further improvedly be: the chute that is laid with several indents on the said tapping body inside circumference wall; The Plug Division periphery that said drive link cooperates with the tapping body is laid with the corresponding convexity of chute of several and tapping body indent, and the convexity on the said drive link can be located in axial sliding on the chute of tapping body inside circumference wall indent.
Further improvedly be: the chute of said indent is 3, and said convexity is 3.
Further improvedly be: said tapping body extends a convexity away from the free end of drive link; The free end of said tapping bar is provided with the polygon through hole, offers the through hole that is connected with the polygon through hole on the said convexity, and said tapping awl comprises tapping cutter and Plug Division; Said Plug Division comprises chimeric end and positioning end; Said chimeric end cross section is corresponding with the polygon through hole to be embedded in the polygon through hole, and said positioning end is located in the protruding through hole, and the periphery of said positioning end is provided with arc groove; The periphery of said convexity is provided with and the corresponding spherical pore of tapping awl arc groove; Be provided with the location ball in the said spherical pore, be arranged with body on the periphery of said convexity and the corresponding position of ball, location, the free end of said convexity is provided with the spacing snap ring of body; Said body is provided with the spring placement hole, is provided with the compression spring between the free end of said body spring placement hole and tapping body.
Through adopting the aforementioned techniques scheme, the invention has the beneficial effects as follows: that end embedding in axial sliding that its drive link of tapping lever apparatus of the present invention has the opening cavity volume is through on the chute of tapping body indent, removable being fixedly arranged on the free end of tapping body away from drive link of tapping awl; This drive link wears a straight pin away from the periphery of the corresponding opening cavity volume of that end of tapping awl, and this tapping body also wears a straight pin near that end periphery of tapping awl, is provided with flexible member between said two straight pins; The present invention utilizes the mitigation impact function of flexible member to make drive link in tapping body chute, have the flexible function with radiai adjustment of axial float, the present invention is installed in can effectively attack on the single head tapping machine makes high-quality internal thread, and the screw thread that processes can random tooth; And screw tap can not fracture; Be installed in when using on the bull tapping machine, the tooth distance can be controlled, compensated automatically to the screw tap on each tapping lever apparatus separately through each tapping lever apparatus of flexible member after just changeing incision simultaneously; Automatically follow the trail of the aperture; Cooperatively interact adjustment and working can realize adjusting automatically the tapping state, make screw tap on each tapping lever apparatus can be soft counter-rotating simultaneously flexibly withdraw from; Reach the purpose of processing simultaneously; Once can process a plurality of screwed holes, improve production efficiency, avoid prior art repeatedly to process and screw thread occurs and leak the phenomenon attack; It is rational in infrastructure, tapping good stability, precision height, flexible operation, production cost are low, is fit to large batch of production.
