Description
Technical field
The present invention relates to lathe riveting frock field, is specifically a kind of lathe riveting frock.
Background technology
Self-clinching nut is usually applied to a kind of nut on thin plate or metal plate, and shape 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, the aperture of preset holes, which is slightly less than, to press
The embossing tooth of nut, the flower tooth of self-clinching nut is squeezed into plate by pressure makes the periphery for causing hole produce plastic deformation, deformation
Thing is squeezed into guide groove, so as to produce the effect of locking.
Press when product carries out pressing nut riveting because nut progress is single, riveting nut generally use outside diameter is determined
Position, because of riveting equipment and riveting nut and product plate, with the presence of slight change, (riveting machine pressure transient has certain floating
Value, pressing nut tolerance variation and the different heat (batch) numbers of material or the nuance of steel mill) can all have an impact to pressing, cause nut
Verticality with respect to riveting interface changes, and ultimately results in the offset of product relative opening position, and influences the quality that presses, and outside diameter positions
So that personnel's inconvenience placing nut, and it is single every time carry out the operation that presses, production efficiency is not also high.
The content of the invention
It is an object of the invention to provide a kind of lathe riveting frock, 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 lathe riveting frock, including upper mold seat and die holder, the upper mold seat bottom surface are slab construction, the lower die
Seat is being provided with the bar that presses, and deep trouth is equipped with the top of the bar that presses, elastic component and positioning column, the elasticity are equipped with the deep trouth
Part one end is fixedly connected with the deep trouth bottom, and the elastic component other end is fixedly connected with the positioning column bottom, the depth
Groove and the positioning column are coaxial, and the positioning column diameter matches with nut aperture.By the way that the compression bar of the prior art is cancelled, directly
Connect and upper mold seat bottom is used into slab construction, also solve existing equipment and produce vibration at work, easily cause upper mold
Seat walks so that compression bar cannot align precompressed position, it is necessary to the problem of using vertically-guided bar, passes through overall tablet knot
Structure, eliminates the use of guide rod, even if upper mold seat walks, offset, nor affects on the operation that presses.In the course of work, positioning
Column not only can carry out internal diameter positioning to self-clinching nut, while the preprocessing hole of product can also be positioned, and ensure that pressure
Precision positioning between riveting nut and preprocessing hole, improves the processing quality to press.
Further, the positioning column includes guide plate and cylinder, and the guide plate is slidably connected with the deep trouth.Pass through guide plate
With the connection of deep trouth side wall so that positioning column is more stablized, and prevents its verticality deflection, improves the stability of frock.
Further, the guide plate cross section is I-shaped isometric up and down.So that positioning column is more stablized, it is prevented
Verticality deflection, improves the stability of frock.
Further, partition plate is also fixed with the nut groove, the partition plate center is equipped with through hole, and the guide plate is located at
On the inside of the partition plate, the cylinder may pass through the through hole.
Further, the elastic component is spring.
Further, it is taper or arc-shaped at the top of the positioning column.So that personnel more easily place preprocessing hole
Into in positioning column, positioned.
Further, product orientation mould is additionally provided with, the product orientation mould is located on the die holder.This product orientation mould
For the mould that can be positioned to product general in industry, due to the positioning action for the bar upper positioning column that presses, product is determined
The required precision of position mould is not high, but can play the role of support to product at this, and help desk personnel is quickly by preset hole
It is set on positioning column, improves the operating efficiency of personnel.
The beneficial effect that the present invention produces：Make original excircle orientation mode to self-clinching nut by pressing into
The internal diameter positioning method of nut, ensures nut internal diameter and riveting face verticality, improves positioning accuracy, improve pressing for product
Quality.
Brief description of the drawings
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the structure diagram of the bar cross section of the invention that presses.
Fig. 3 is the structure diagram of positioning column of the present invention.
In figure：Upper mold seat 1, die holder 2, the bar 3 that presses, positioning column 3.1, cylinder 3.1.1, guide plate 3.1.2, elastic component 3.2,
Deep trouth 3.3, partition plate 3.4, product orientation mould 4.
Embodiment
Technical scheme is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill
Personnel's all other embodiments obtained without making creative work, belong to the scope of protection of the invention.
As shown in Figs. 1-3, a kind of lathe riveting frock, including upper mold seat 1 and die holder 2,1 bottom surface of upper mold seat is flat
