Abstract
The present invention relates to a kind of plate nut installation method, the installation method of more particularly to multiple plate nut annular spreads.It is characterized in that：According to a kind of supporting plate of plate nut size design, plate nut is clamped in by target workpiece surface by bolt and clamp nut, enlarging is then carried out using flaring tool.The beneficial effects of the invention are as follows：For the complex target workpiece of structure, due to narrow space, it is impossible to installation directly is fixed to single plate nut.Using above-mentioned installing and fixing method, plate nut can be simply and reliablely fixed, and does not injure plate nut flared end or screw thread, installation reliability can be significantly ensured and improve installation effectiveness.
Description
Technical field
The present invention relates to a kind of plate nut installation method, the installation side of more particularly to multiple plate nut annular spreads
Method.
Background technology
The load-carrying member being attached using bolt, for convenience of assembling need use can be directly anchored to target workpiece and
It is capable of the plate nut of anti-rotation.Plate nut is limited by D-shaped supporting plate and rotated, and restriction axial movement is fixed by enlarging,
Plain nut can be substituted and meet use requirement.Plate nut is installed preceding, it is necessary to be fixed.
The content of the invention
The purpose of the present invention is：Propose a kind of installing and fixing method of annular spread adjacent pallets nut.According to this method
A kind of supporting plate is designed, adjacent three plate nuts are held up simultaneously, both sides plate nut are clamped by bolt, clamp nut
In target workpiece, the plate nut for being pointed to centre using flaring tool carries out enlarging, so as to realize installation.
The technical problem to be solved in the present invention：Plate nut is before enlarging, it is necessary to assure be pressed on target workpiece peace
Dress face.It can be realized by frock and single plate nut is compressed and installed.If due to narrow space cause frock without
Method is placed, it is necessary to consider how to be compressed plate nut to be installed using both sides plate nut mounting hole.
The technical scheme is that：Plate nut structure is as shown in figure 1, according to a kind of supporting plate of plate nut size design
(Fig. 2), each tool sizes relation in target workpiece surface (Fig. 4) is clamped in by bolt and clamp nut (Fig. 3) by plate nut
As shown in figure 5, then carrying out enlarging (Fig. 6) using flaring tool.
A kind of installing and fixing method of plate nut, it is characterised in that：Circular arc supporting plate 3 is made, outside has more than at 3
Breach, breach is U-shaped, and gap width need to be more than plate nut end of thread outer surface diameter；The side of clamp nut 6 is machined with rotation stop
Boss, prevents one cylinder counterbore of processing above rotation, screw thread, pit is used to hide supporting plate spiral shell when fixed for blocking side surface of workpiece
Box thread end；The major diameter of thread of hold-down bolt 5 need to be less than plate nut bottom diameter, and length is enough also cross riveting axle nut and pressure
Tight nut；3 plate nut flared ends are stretched into the mounting hole supporting plate 3 of axisymmetric workpiece 1 to hold up；In two hold-down bolts 5
Upper gasket 4 is covered, is penetrated out of both sides plate nut 2 hole, clamp nut 6 is tightened and completes fixation；After fixation rotate flaring tooling to
Lower movement, the plate nut for being pointed to centre position carries out enlarging operation.Complete after installing, move each tool ejector and integrally
It is dynamic, carry out the installation of next plate nut.
The beneficial effects of the invention are as follows：For the complex target workpiece of structure, due to narrow space, it is impossible to directly
Installation is fixed to single plate nut.Using above-mentioned installing and fixing method, plate nut can be simply and reliablely fixed, and
Plate nut flared end or screw thread are not injured, can significantly be ensured installation reliability and be improved installation effectiveness.

Embodiment
Below by specific embodiment, the present invention is described in further detail.
When plate nut annular spread quantity is that 50, spacing is 20mm, the end of thread uses M8, outer surface diameter for Ф
11mm, D-shaped plate thickness is 4mm, and when enlarging external diameter is Ф 12mm, adoptable frock size is：Support plate thickness is 5mm；
There is breach at 3, U-shaped mouth width is 13mm, and spacing is 20mm；Hold-down bolt, clamp nut use M6 screw threads.
