Abstract
The invention relates to a mounting method for supporting plate nuts, in particular to a mounting method for annular distribution of the supporting plate nuts. The method is characterized in that a supporting plate is designed according to the size of the supporting plate nuts; the supporting plate nuts are clamped on the surface of a target workpiece through bolts and compressing nuts; and then, a flaring tool is adopted to carry out flaring. The mounting method has the beneficial effects that for the target workpiece of the complex structure, due to the small and narrow space, the single supporting plate nut cannot be directly and fixedly arranged. By the adoption of the fixing and mounting method, the supporting plate nuts can be simply and reliably fixed; the flaring ends or threads of the supporting plate nuts cannot be damaged; the mounting reliability can be remarkably ensured; and the mounting efficiency is improved.
Description
Technical field
The present invention relates to a kind of plate nut installation method, particularly the installation method of multiple plate nut annular spread.
Background technology
Adopt bolt to carry out the load-carrying member that connects, need to adopt for convenience of assembling and directly can be fixed on target workpiece and can the plate nut of anti-rotation.Plate nut is rotated by the restriction of D shape supporting plate, is fixed restriction and moves axially, can substitute plain nut and meet instructions for use by enlarging.Plate nut needs to be fixed before installing.
Summary of the invention
The object of the invention is: the installing and fixing method proposing a kind of annular spread adjacent pallets nut.Design a kind of gripper shoe according to this method, adjacent three plate nuts are held up simultaneously, by bolt, clamp nut, both sides plate nut is clamped in target workpiece, adopt flaring tool to carry out enlarging to being positioned at middle plate nut, thus realize installing.
The technical problem to be solved in the present invention: plate nut, before enlarging, must ensure to be pressed on target workpiece installed surface.Can realize compressing single plate nut and installing by frock.If because narrow space causes frock to place, need to consider how to utilize both sides plate nut installing hole to be compressed by plate nut to be installed.
Technical solution of the present invention is: plate nut structure as shown in Figure 1, according to a kind of gripper shoe (Fig. 2) of plate nut size design, by bolt and clamp nut (Fig. 3), plate nut is clamped in each tool sizes relation in target workpiece surface (Fig. 4) as shown in Figure 5, then adopts flaring tool to carry out enlarging (Fig. 6).
An installing and fixing method for plate nut, is characterized in that: make circular arc gripper shoe 3, there are the 3 above breach in place in outside, and breach is U-shaped, and gap width need be greater than plate nut end of thread outer surface diameter; Clamp nut 6 side is processed with spline boss, and prevent from rotating for blocking side surface of workpiece, process a cylinder counterbore above screw thread, time fixing, pit is used for hiding the plate nut end of thread; Hold-down bolt 5 major diameter of thread need be less than plate nut bottom diameter, and length is enough simultaneously through riveting spindle nut and clamp nut; 3 plate nut flared end are stretched into axisymmetric workpiece 1 installing hole gripper shoe 3 to hold up; Overlap upper gasket 4 at two hold-down bolts 5, penetrate in both sides plate nut 2 hole, tighten clamp nut 6 and complete fixing; Rotate flaring tooling after fixing to move down, enlarging operation is carried out to the plate nut being positioned at centre position.After completing installation, each tool ejector is moved integrally, carries out the installation of next plate nut.
The invention has the beneficial effects as follows: for the target workpiece that structure is comparatively complicated, due to narrow space, directly can not be fixed installation to single plate nut.Adopt above-mentioned installing and fixing method, plate nut can be fixed simple and reliablely, and do not injure plate nut flared end or screw thread, installation reliability can be guaranteed significantly and improve installation effectiveness.

Detailed description of the invention
Below by specific embodiment, the present invention is described in further detail.
When plate nut annular spread quantity be 50, spacing is 20mm, the end of thread adopts M8, outer surface diameter be Ф 11mm, D shape plate thickness is 4mm, and when enlarging external diameter is Ф 12mm, adoptable frock is of a size of: gripper shoe thickness is 5mm; Have 3 place's breach, U-shaped mouth width is 13mm, and spacing is 20mm; Hold-down bolt, clamp nut adopt M6 screw thread.
