Abstract
The utility model discloses a nut tapping machine constructs, its characterized in that: including rotary main shaft, the chuck, the backstop lid, screw tap and guide arm, rotary main shaft rotates and locates on the fuselage, chuck fixed connection is in rotary main shaft's rear end, the chuck is equipped with the draw -in groove, the draw -in groove width is greater than the excircle size that tapping nut outer hexagonal formed, the guide arm passes from rotary main shaft's centre bore activity, the excircle size phase -match that the aperture of centre bore and tapping nut outer hexagonal formed, the preceding rod end of guide arm and the caudal peduncle fixed connection of screw tap, the hole aperture phase -match of guide arm external diameter and tapping nut, after being less than 90 degrees buckling, passes through by the back rod end of guide arm the draw -in groove, guide arm axially movable, the distance of guide arm rearward movement is subject to the backstop lid, the position fixed mounting of terminal surface certain distance outside leaving the chuck is covered in the backstop. The utility model discloses be exclusively used in outer hexagon nut's automatic tapping processing, the tapping adds the man -hour screw tap need not carry out the tool backlash movement, simple structure, and production efficiency is high.
Description
Technical field
This utility model relates to a kind of tapper for outer-hexagonal nut self-tapping processing, is specifically related to the tap mechanism of a kind of tapper.
Background technology
Outer-hexagonal nut needs to carry out the tapping processing of screwed hole after making profile and endoporus in upsetting, course of action such as needing to carry out that the clamping of workpiece, screw tap feed, screw tap withdrawing and workpiece unclamp is processed in tapping, so the structure of the tapper mechanism of equipment particularly equipment can be considerably complicated, production efficiency is not high yet.
Summary of the invention
In view of currently known technology Problems existing, the technical problems to be solved in the utility model is to be in that to provide a kind of tapping to add man-hour screw tap not need to carry out tool backlash movement, simple in construction, the tap mechanism that production efficiency is high.
For solving above-mentioned technical problem, this utility model has adopted the following technical scheme that:
Tap mechanism, it is characterized in that: include rotating main shaft, chuck, rear door, screw tap and guide rod, rotate main axis and be located on fuselage, chuck is fixedly connected on the rear end rotating main shaft, chuck is provided with draw-in groove, the excircle dimension that card well width is formed more than institute's tapping nut outer-hexagonal, guide rod passes from the centre bore activity rotating main shaft, the excircle dimension that the aperture of centre bore and institute's tapping nut outer-hexagonal are formed matches, the front rod end of guide rod is fixing with the caudal peduncle of screw tap to be connected, the endoporus aperture of guide rod external diameter and institute's tapping nut matches, the rear rod end of guide rod passes through described draw-in groove after carrying out the bending less than 90 degree, guide rod is axially movable, the distance that guide rod is moved rearwards by is limited to described rear door, rear door fixedly mounts in the position leaving chuck outer face certain distance.
nullAfter adopting technique scheme，The tapping course of processing that this utility model realizes is: tapping is initial，Feed mechanism will treat that tapping nut delivers to screw tap conehead，When nut just starts to abut against screw tap，Screw tap retreats and drives guide rod to be moved rearwards by until guide rod tail end contacts with rear door，At this moment screw tap starts feed and carries out tapping (rotation of screw tap is driven by guide rod，The rotation of guide rod is driven by chuck，The rotation of chuck is driven by rotating main shaft)，When the conehead part of screw tap completely extends across nut inner hole，The threaded hole of nut completes，Nut can enter on the caudal peduncle of screw tap，When feed mechanism return，Nut can depart from feed mechanism，In disengaging process，Screw tap is drawn forward dynamic，Then certain interval is reserved between guide rod tail end and rear door，At this moment the nut machined near the tapping of guide rod tail end can deviate from guide rod through draw-in groove and above-mentioned gap，Then from discharging opening out，Circulate according to this，Realize the self-tapping processing of outer-hexagonal nut.Owing to above-mentioned whole course of processing plug tap does not need to carry out tool backlash movement, therefore it is not only simple in structure, and production efficiency is high.
Accompanying drawing explanation
This utility model has drawings described below:
Fig. 1 is structure chart of the present utility model,
Fig. 2 is the A direction view of Fig. 1.
Detailed description of the invention
Accompanying drawing illustrates the technical solution of the utility model, further describes each relevant details and the operation principle thereof of embodiment below in conjunction with accompanying drawing:
nullAs shown in the figure，Tap mechanism of the present utility model，Including rotating main shaft 3、Chuck 4、Rear door 5、Screw tap 1 and guide rod 2，Rotate main shaft 3 rotation and be located on fuselage by power drive，Chuck 4 is fixedly connected on the rear end rotating main shaft 3，Chuck 4 is provided with draw-in groove 41，The excircle dimension that draw-in groove 41 width is formed more than institute's tapping nut 100 outer-hexagonal，Guide rod 2 passes from the centre bore 31 rotating main shaft 3 is movable，The excircle dimension that the aperture of centre bore 31 and institute's tapping nut 100 outer-hexagonal are formed matches，The front rod end of guide rod 2 is fixed together after welding with the caudal peduncle of screw tap 1，The endoporus aperture of guide rod 2 external diameter and institute's tapping nut 100 matches，The rear rod end 21 of guide rod 2 passes through described draw-in groove 41 after carrying out the bending less than 90 degree，Guide rod 2 is axially movable，The distance that guide rod 2 is moved rearwards by is limited to described rear door 5，Rear door 5 fixedly mounts in the position leaving chuck 4 outer face certain distance.
