Description
Technical field
The present invention relates to synchronous pressure riveting tool field, specifically a kind of synchronous pressure riveting tool.
Background technology
Riveting nut on the thin plate or metal plate of machine tool enclosure, the usual profile of nut is rounded, and one end is with embossing
Tooth and guide groove, its principle are that the preset holes of metal plate are pressed into by being embossed tooth, it is however generally that, preset holes on thin plate or metal plate
Aperture is slightly less than the embossing tooth of self-clinching nut, and the flower tooth of self-clinching nut is squeezed into plate by pressure produces the periphery for causing hole
Plastic deformation, deformations are squeezed into guide groove, so as to produce the effect of locking.
Pressed when product carries out pressing nut riveting because nut progress is single, riveting nut generally use external diameter is determined
Position, product are generally positioned by jig, and such a mode has following defect：1st, because of riveting equipment and riveting nut and product
With the presence of slight change, (riveting machine pressure transient has certain float value, pressing nut tolerance variation and material not to sheet material
With heat (batch) number or the nuance of steel mill) can all have an impact to pressing, cause nut to be changed with respect to the perpendicularity at riveting interface, finally
Cause product to be offset relative to hole position, and influence the quality that presses；2nd, the positioning precision of jig can also produce to the position of relative opening
It is raw to influence so that riveting precision is difficult control；3rd, single hole carries out the operation that presses every time, particularly with multiple on a product
Hole needs the situation of self-clinching nut, and production efficiency is not also high.
The content of the invention
It is an object of the invention to provide a kind of synchronous pressure riveting tool, to solve the problems mentioned in the above background technology.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of synchronous pressure riveting tool, including upper bolster and die shoe, the upper bolster bottom surface are provided with briquetting, the lower mould
Be provided with the bar that presses on seat, the briquetting with the bar that presses is vertically opposite on the upper bolster and the die shoe respectively sets
Put, briquetting lower surface planar structure, it is not straight at one that at least three are respectively equipped with the upper bolster and the die shoe
The relative briquetting and the bar that presses on line, the bar top surface that presses are provided with circular groove, be provided with the circular groove elastic component and
Locating dowel, it is described positioning column bottom be fixedly connected with the elastic component, can in the circular groove elastic telescopic, the circular groove and institute
It is coaxial to state locating dowel, the locating dowel external diameter matches with riveting nut internal orifice dimension.
Further, the locating dowel includes guide plate and cylinder, is additionally provided with dividing plate in circular groove, the cylinder through it is described every
Upward, its positioning action, the guide plate is slidably connected plate with the circular groove.The guide plate is located on the inside of the dividing plate, the post
Body may pass through the through hole protrusion and the baffle surface.
Further, the locating dowel cross section generally " soil " font.
Further, the elastic component is spring.
Further, it is taper or circular arc at the top of the locating dowel.
Further, the briquetting basal diameter is more than the bar top surface diameter that presses.
Beneficial effect caused by the present invention：1st, by original excircle orientation mode to self-clinching nut, made into by pressing
Riveting nut leads to positioning method by the internal diameter of locating dowel, improves positioning precision, also ensures nut internal diameter and riveting face perpendicularity,
Avoid it integral inclined when processing, improve the quality that presses of product.2nd, multiple positions on product are once pressed
Riveting is molded, and improves operating efficiency.3rd, locating dowel can directly play a part of positioning product, without being further added by product orientation dress
Put and (refer in particular to have at least three preprocessing holes not point-blank on product herein), simplify the structure of frock.4th, pass through
At least three point-blank locating dowel can not only not position to riveting nut, and by self-clinching nut to product
Upper preprocessing hole similarly positions, and avoids the position skew between preprocessing hole and riveting nut on product, improves product
The precision of riveting processing, improve the controllability of precision.5th, design of the briquetting bottom surface more than the shank diameter that presses solves existing
Equipment produces vibration at work, easily causes walking for upper bolster so that briquetting can not align precompressed position, it is necessary to make
The problem of with vertically-guided bar, upper module is slightly offset, and can't influence the effect that presses.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is schematic structural view of the invention；
Fig. 2 is press bar and the structural representation of briquetting cross section of the invention；
