Abstract
A kind of structure of punching machine connecting rod, it includes connecting rod shank and the connecting rod FE Tiler of connecting rod shank bearing shell oral area is arranged on the first bolt, and thread bush is studded with the endoporus at described connecting rod shank central axis position, it is characterized in that：Between the described endoporus at connecting rod shank central axis position and the cylindrical of thread bush, be within the mode of conical bore and the cylindrical axis of cone cooperate and carve what is be combined, connecting rod shank is fixed with thread bush at lower port position, in order to reach both best fit effects, described connecting rod shank（1）The endoporus and thread bush at central axis position（3）External conicity be Morse's taper, a kind of structure of punching machine connecting rod of the invention, scrappage relatively low advantage long with service life.
Description
Technical field
The present invention relates to a kind of structure of punching machine connecting rod, belong to punching machine technical field.
Background technology
It is well known that the connecting rod of punching machine is the important spare part of punching machine, what connecting rod was connected through a screw thread
Method is connected with ball screw, and impulsive force is loaded on ball screw, so that the sliding block of driving mechanical forcing press carries out work
Make, so, the internal thread that ball screw is installed on connecting rod shank is easily damaged, once such case occurs, then whole connecting rod is just reported
It is useless, thus, improve the structure of existing connecting rod, the scrappage of reduction connecting rod is the problem of those skilled in the art should consider.
The content of the invention
It is an object of the invention to：It is relatively low for existing machinery press connecting rod service life, the larger defect of scrappage,
The present invention provides a kind of structure of new punching machine connecting rod.
The present invention realizes that the technical method that above-mentioned purpose is used is：A kind of structure of described punching machine connecting rod,
It includes connecting rod shank（1）And use the first bolt（4）Installed in connecting rod shank（1）The connecting rod FE Tiler of bearing shell oral area position（2）, it is described
Connecting rod shank（1）Thread bush is studded with the endoporus at central axis position（3）, described thread bush（3）Central axis position is formed with peace
The internal thread of ball screw is filled, it is characterized in that：Described connecting rod shank（1）The endoporus and thread bush at central axis position（3）It is outer
Between circle, be within the mode of conical bore and the cylindrical axis of cone cooperate and carve what is be combined, connecting rod shank（1）With thread bush（3）
Fixed at lower port position, further：Described connecting rod shank（1）With thread bush（3）Lower port position be formed respectively with first
Ring flange（6）With second flange disk（7）, described first flange disk（6）With second flange disk（7）Between use the second bolt
（5）It is fixed together.In order to reach both best fit effects, described connecting rod shank（1）The endoporus at central axis position with
Thread bush（3）External conicity be Morse's taper.
Beneficial effect：In the present invention, the internal thread for installing ball screw is not to be fabricated directly in connecting rod shank（1）On,
But manufacture in thread bush（3）In endoporus, thus, work as thread bush（3）Internal thread damage when, only need to change thread bush（3）I.e.
Can be with, without changing whole connecting rod, so, a kind of structure of punching machine connecting rod of the invention, report long with service life
The relatively low advantage of useless rate.
Brief description of the drawings
Fig. 1 is the structure chart of the present invention.
Shown in figure：1 it is connecting rod shank, 2 be connecting rod FE Tiler, 3 be thread bush, 4 be the first bolt, 5 be the second bolt, 6 is
First flange disk, 7 are second flange disks.
Embodiment
With reference to Fig. 1, embodiment of the invention is：
A kind of structure of described punching machine connecting rod, it includes connecting rod shank（1）And use the first bolt（4）Installed in connecting rod
Body（1）The connecting rod FE Tiler of bearing shell oral area position（2）, described connecting rod shank（1）Thread bush is studded with the endoporus at central axis position
（3）, described thread bush（3）Central axis position is formed with the internal thread for installing ball screw, it is characterized in that：Described connecting rod shank
（1）The endoporus and thread bush at central axis position（3）It is cylindrical between, be within conical bore and the mode phase interworking of the cylindrical axis of cone
Conjunction carves what is be combined, connecting rod shank（1）With thread bush（3）Fixed at lower port position, further：Described connecting rod shank（1）
With thread bush（3）Lower port position be formed respectively with first flange disk（6）With second flange disk（7）, described first flange disk
（6）With second flange disk（7）Between use the second bolt（5）It is fixed together.In order to reach both best fit effects, institute
The connecting rod shank stated（1）The endoporus and thread bush at central axis position（3）External conicity be Morse's taper.
Claims (3)
