The tool is used for axially clamping a ring-shaped skirt edge of the flange nut by virtue of upper and lower clamping plates, clamping and positioning the profile section of the flange nut by virtue of a profile positioning channel on the upper clamping plate, positioning the flange end surface of the flange nut by virtue of a positioning plane of the lower clamping plate, guaranteeing the vertical relationship between the flange end surface and the profile section of the flange nut after clamping by virtue of the vertical relationship between a vertical extending profile positioning channel and a horizontal extending positioning plane, namely guaranteeing that the flange end surface of the flange nut is vertical to the axis of an inner screw hole, so that the problem that the perpendicularity between the axis of the inner screw hole and the flange end surface in the tapping and clamping process of the flange nut in the prior art cannot be guaranteed is solved.
Description
Technical field
The present invention relates to a kind of flange nut tapping tool.
Background technology
Flange nut (comprising hexagon nut with flange, 12 angle flange face nuts etc.), as coordinating the industrial foundation part played the role of fastening with bolt, screw and screw rod, is used widely in fields such as aviation, boats and ships, automobiles.As depicted in figs. 1 and 2, for hexagon nut with flange, flange nut has the six side's sections 100 and flange section 200 that are wholely set, flange section 200 is provided with the annular skirt of projection on the periphery of flange nut along 201, the opposing end face of six side's sections 100 and flange section 200 is end face of flange 202 and the six square end faces of flange nut, and is respectively equipped with the chamfering tangent plane of annular at the two ends of the inner bolt hole of flange nut.The main required precision of flange nut is that this just requires that the end face of flange 202 of flange nut in tapping process must keep plumbness with screw tap for the perpendicularity requirement between the axis of inner bolt hole and end face of flange 202.Conventional processing method adopts lathe tapping, clamp six side's side faces of flange nut with triangle chuck during lathe tapping, processed by the screw tap of knife rest or top upper installation again, but easily occur clamping not positive phenomenon due to during triangle clamping chuck nut six side's side face, cause end face of flange and the screw tap out of plumb of flange nut, also axis and the end face of flange out of plumb of the inner bolt hole of flange nut is just made, the product perpendicularity processed in this approach is easily overproof and quality unstable, and clamping is once again on chuck often to process product needed, working (machining) efficiency is very low.
Summary of the invention
The object of this invention is to provide a kind of flange nut tapping tool, be intended to solve the unwarrantable problem of perpendicularity between the axis of flange nut inner bolt hole in tapping clamping process in prior art and end face of flange.
In order to realize above object, in the present invention, the technical scheme of flange nut tapping tool is as follows:
Flange nut tapping tool, comprise relative spacing up and down for being fixed on fixed mount on Drilling machines bench and upper assembling thereof, lower plate, train wheel bridge offers the profile placed channel of the profile section vertical extension of spin-ended plug-in mounting vertically for flange nut, lower plate is provided with the channel of chip removal be positioned at below profile placed channel, the part adjacent with described channel of chip removal on the upper face of lower plate is the plane of orientation for the horizontal-extending of block under the end face of flange of flange nut, the part adjacent with described profile placed channel on the lower face of train wheel bridge is the seal face on the pressed on ring end face on annular skirt edge for being pressed on flange nut.
Profile placed channel is the locating slot extended in the horizontal direction, and the relative both sides trough wall surface of locating slot is for the spin-ended wall coordinated that leads along groove depth direction and the relative both sides of the outer peripheral face of the profile section of flange nut.
Flange nut tapping tool according to claim 2, is characterized in that, locating slot has two or more and interval is arranged on train wheel bridge, and the groove width in each locating slot between at least two two spin-ended walls is different.
Train wheel bridge offers the upper plate dumping pit that the flange section for flange nut passes axially through, upper plate dumping pit is communicated with locating slot, and the projection of loading and unloading material hole on the upper face of lower plate and channel of chip removal interval are arranged.
The notch of locating slot is in the side of train wheel bridge, and the groove bottom part of locating slot is communicated with described upper plate dumping pit.
Channel of chip removal is the chip area be arranged in parallel with locating slot, and the groove width of chip area is not more than the groove width of locating slot.
Lower plate offers the lower plate dumping pit supplying the flange section of flange nut to pass axially through, lower plate dumping pit and channel of chip removal are communicated with or interval, on the lower ending opening that the projection of lower plate dumping pit on the lower face of train wheel bridge is in locating slot or be on the through hole that is communicated with locating slot.
The governor motion for regulating the spacing between upper lower plate is provided with between lower plate and train wheel bridge and/or between lower plate and fixed mount.
In upper and lower clamping plate, one is fixed on fixed mount, another is connected on train wheel bridge by governor motion is adjustable up and down.
Governor motion comprises the securing member be fastenedly connected on upper and lower clamping plate.
The present invention is by upper, lower plate comes the annular skirt edge from axial grip flange nut, the profile section Set and Positioning to flange nut is realized again by the profile placed channel on train wheel bridge, positioned by the end face of flange of the plane of orientation on lower plate to flange nut, then after ensureing clamping by the vertical relation between the profile placed channel that vertically extends and the plane of orientation of horizontal-extending, vertical relation between the end face of flange of flange nut and profile section, namely end face of flange and the inner bolt hole axes normal of flange nut is ensured, and in tapping process, the axial float of flange nut is stoped again by the pressuring action of the seal face on train wheel bridge to the pressed on ring end face on the annular skirt edge of flange nut, carrying out in process like this, after screw tap is incorporated into the inner by the chamfering of the port of flange nut, the location that this frock can realize flange nut by axial grip and circumferential spline, the perpendicularity between the inner bolt hole axis of clamping rear flange nut and end face of flange is ensured by frock self structure, the scheme being ensured perpendicularity by assembling mode is needed compared to existing technology, in the present invention, the perpendicularity precision of flange nut between clamping rear end face and inner bolt hole axis will be higher, thus the unwarrantable problem of perpendicularity solved between the axis of flange nut inner bolt hole in tapping clamping process in prior art and end face of flange.
