Description
Technical field
The invention belongs to electric threading technical field of tools is and in particular to a kind of high accuracy big footpath servo feed tapping power
Head, is matched with tapper or similar equipment, and metal works are processed with required internal thread hole.
Background technology
Technical information with regard to tapper unit can be seen in disclosed Chinese patent literature, and such as CN202825375U pushes away
Recommend " auto-feed borehole chasing bar ", a kind of typical " self-tapping providing as Authorization Notice No. CN201350535Y
Power head mechanism ", this patent formula install on support cylinder and be connected with cylinder piston rod and with live spindle simultaneously
The push rod of row, although this patent can embody the technique effect of the 2nd section of record of its Instructions Page 2, because it belongs to gas
Dynamic formula tapper unit device category, so-called pneumatic type tapper unit device refers to the displacement of piston rod by cylinder piston rod
Control that is to say, that stroke is processed by pneumatic control（Advance or retreat）, thus the shortcoming of pneumatic feeding tapper unit device
One of, due to compressed air being used as the power source of piston rod movement, thus must provide for compressed air source unit such as air compression
The device of machine or air pump etc, causes pneumatic feeding tapper unit device only relying on the shape that auxiliary equipment is air compressor machine etc.
Just it is able to work under state；Two, due to processing stroke, for example to advance be by pneumatic realization, and therefore pace must be passed through
Hydraulic damper is adjusted, but the non-linear shakiness that can lead to the tapping course of processing of the unstability of gas and hydraulic damping
Fixed, not only easily affect tapping precision, and the service life of tapping tool such as tapping-head can be undermined；Three, due to need with
F.F. is realized in collision by means of hydraulic damper and work enter between switching, thus be that noise during tapping is larger, especially during processing
It is that noise is bigger, thus affecting the environment of operation field when production scene is equipped with multiple stage pneumatic type tapper unit device
（Sound pollution）；Fourth, due to being difficult in process or even cannot accomplish to stroke at all（F.F. stroke and work are carried out
Journey）Accuracy controlling it is therefore necessary to by the loaded down with trivial details and machinery adjustment of complexity, and this loaded down with trivial details and complicated machinery adjustment is on the one hand
Impact working performance, on the other hand increases the working strength of operator, and especially machinery adjustment is carried out in a manual manner by operator,
And the precision of manual mode adjustment is due to, the precision of therefore adjustment related to factors such as the experience of operator, responsibility and emotions
Objectively it is difficult to ensure；Fifth, due to control model limitation, thus be difficult to by programmable controller（PLC）It is controlled.
Application for a patent for invention publication No. CN103317376A disclosed " servo feed tapper unit device " comprehensively disappears
Except the shortcoming of described five aspects of aforementioned CN201350535Y, specifically can be found in the description the 0020th of CN103317376A
To 0040 section, especially see the 0015th section of description.
But above-mentioned CN103317376A yet suffers from following shortcoming：First, due to axle sleeve（This patent claims trocar sheath, with
Similarly hereinafter）Upper end end face be fixed on the bottom of transmission control chamber in a non-movable manner, lower end is configured to tediously long longitudinal direction and hangs
Arm end, and connected a slip cap threadably in lower end, in the axle sleeve chamber of axle sleeve（Patent claims overcoat tube chamber）
The inner sleeve that interior setting is slidably matched with slip cap, arranges bearing positioning spacer in the internal canula lumen of inner sleeve, is corresponding to
The cutter spindle that the middle position setting of bearing positioning spacer can move up and down, thus on the one hand make the knot of whole work-piece tapping mechanism
Structure becomes very complicated, brings puzzlement to manufacture and assembly, the stability of the up and down motion of another aspect cutter spindle is difficult to keep,
The final impact Tapping Quality to workpiece for the tapping tool；Second, due to using being arranged on travelling carriage（Patent claims sliding shoe）On
The cooperation of a pair of guide rails in guide wheel and the cavity wall in the transmission control chamber chamber being arranged on transmission control chamber and the travelling carriage that builds with
The technique effect that rigid matching relationship between transmission control chamber is brought can not reach expection, thus travelling carriage moves up and down
The rigid requirements of flattening effect and expectation embodiment really do not embody；Third, because travelling carriage sets towards one end of splined shaft
It is equipped with a clamping ring, will be locked with the hub splines with splined shaft from clamping ring, driven by clamping ring when travelling carriage moves up and down
Hub splines, is expanded the fortune up and down that the discoid axle sleeve union joint setting drives cutter spindle work to follow in sb's footsteps by hub splines lower end
Dynamic, thus travelling carriage shows as indirect action to the model of action of cutter spindle, one side active force is affected, and on the other hand presss from both sides
Circle is difficult to ensure to the effect of clamping of the upper end of hub splines, there is the anxiety loosening or even shaking off.
For above-mentioned prior art, still have improved necessity, for this applicant made positive and beneficial design and
Define technical scheme described below.
Content of the invention
