Technical field
The utility model is mainly concerned with the pharmaceutical machine apparatus field, refers in particular to a kind of automatic lamp-checking machine.
Background technology
In the pharmaceutical machine apparatus field, lamp inspection machine is that a kind of optical imaging, computing machine of utilizing compares principle to image, and packages for liquid drug quality is carried out the seriation specialized equipment that automatic intelligent detects.The view data that Computer Analysis collects, liquid towards drug quality judge, reach a conclusion and command lamp inspection machine on the rejecting oscillating arm mechanisms underproof medicine bottle is rejected.
Pressure lever mechanism is as the vitals of restriction ampoule bottle upper end in the automatic lamp-checking machine, the transverse shaft that it comprises depression bar and is located at the pressure head assembly of depression bar opposite end respectively and is used for lifting.Depression bar comprises the body of rod and bar head, and the pressure head assembly comprises pressure head cover and pressure head, and bar head and pressure head are respectively charged into the opposite end of pressure head cover.Two cover bearings are housed on the transverse shaft, and a cover bearing in the outer part rolls along cam face, drives the depression bar lifting, and then drives the pressure head restriction or unclamp ampoule bottle.A cover bearing in the inner part rolls along platen top gathering sill side arm when the depression bar lifting, play the guiding role in the depression bar lifting.
Pressure head directly contacts with the inwall of pressure head cover in the existing pressure lever mechanism, during rotation, pressure head and pressure head inner room are sliding friction, and the friction force of generation is bigger, cause ampoule bottle to block and can't rotate, and then influence is carried out foreign matter to ampoule bottle and detected with rotary support.
The utility model content
The technical problems to be solved in the utility model just is: at the technical matters that prior art exists, the utility model provide a kind of simple and compact for structure, with low cost, process and assemble is easy, adaptability is strong, the automatic lamp-checking machine pressure lever mechanism of good reliability.
For solving the problems of the technologies described above, the utility model by the following technical solutions.
A kind of automatic lamp-checking machine pressure lever mechanism, comprise depression bar and pressure head component, described pressure head component comprises pressure head cover and pressure head, and described depression bar is sheathed on the upper end of pressure head cover, it is characterized in that: described pressure head is located in the lower end of pressure head cover and can be rotated around the axis of pressure head by bearing holder (housing, cover).
As further improvement of the utility model:
Described pressure head comprises connecting portion and press keeping section, and described bearing holder (housing, cover) is located at the upper end of connecting portion and is fixed by the attachment screw that is positioned at the connecting portion end, and described press keeping section is connected in the lower end of connecting portion.
Described press keeping section is provided with the containing cavity that cooperates with bottle, and the top of described containing cavity offers dodges the hole.
Compared with prior art, advantage of the present utility model just is:
1, the utility model automatic lamp-checking machine pressure lever mechanism, have simple and compact for structure, with low cost, advantages such as process and assemble is easy, adaptability is strong, good reliability, pressure head is supported in the pressure head cover by bearing, only be rolling friction during rotation, the friction force that produces is very little, helps the rotation of ampoule bottle;
2, the utility model automatic lamp-checking machine pressure lever mechanism, the containing cavity of press keeping section bottom offers and dodges the hole in pressure head, is used to overcome the influence that the mouth-sealed portion out-of-shape is caused behind the ampoule bottle sintering.
3, the utility model automatic lamp-checking machine pressure lever mechanism, only need pass through threaded engagement, in time adjust the degree of depth in the depression bar screw-in pressure head cover, can overcome the error in length that depression bar, pressure head or pressure head cover cause because of processing, do not need depression bar, pressure head or pressure head cover are carried out Precision Machining.

Embodiment
Below with reference to specific embodiment and Figure of description the utility model is described in further details.
As depicted in figs. 1 and 2, the utility model automatic lamp-checking machine pressure lever mechanism, comprise depression bar 1 and pressure head component 2, depression bar 1 is connected to pressure head with pressure head 4 and overlaps 3 two ends, it is depression bar 1 is sheathed on pressure head cover 3 by threaded engagement upper end, pressure head 4 is connected in the lower end of pressure head cover 3, and pressure head 4 is used for cooperating with bottle and rotating with bottle.Pressure head 4 is sheathed in the pressure head cover 3 by bearing 8 and also can rotates around the axis of pressure head 4 in the utility model.Pressure head 4 comprises connecting portion 41 and press keeping section 42, and press keeping section 42 adapts with the shape of bottle, and bearing 8 is sheathed on the upper end of connecting portion 41 and fixes by the attachment screw 43 that is positioned at connecting portion 41 ends, and press keeping section 42 is connected in the lower end of connecting portion 41.It is the ladder endoporus that pressure head overlaps ends that are connected with pressure head 4 in 3, is positioned at the small-bore endoporus that is of top, and what be positioned at the below is the heavy caliber endoporus, and the outer wall of bearing 8 is then by being located in the heavy caliber endoporus.The upper end of connecting portion 41 offers screw hole, and the attachment screw 43 that is arranged in small-bore endoporus is installed in screw hole and compresses bearing 8, and guarantees that the pressure head 4 that bearing 8 is housed can overlap rotation in 3 at pressure head.
In the present embodiment, press keeping section 42 is provided with the containing cavity 421 that cooperates with bottle, and the top of containing cavity 421 offers dodges hole 422, is used to overcome the influence that the mouth-sealed portion out-of-shape causes behind the ampoule bottle sintering, has strengthened the adaptability of press keeping section 42 greatly.In the present embodiment, the degree of depth of dodging hole 422 is 4mm to 5mm.
In the present embodiment, depression bar 1 and pressure head component 2 are connected by threaded engagement, adopt the mode of threaded engagement, can adjust the physical length after depression bar 1 and pressure head component 2 combinations as required in real time, and it is better cooperated with bottle.
In the present embodiment, the junction with depression bar 1 on the pressure head cover 3 is provided with the lock assembly 5 that is used for locking depression bar 1 position, and lock assembly 5 comprises lock piece 6 and locking hole 7, and locking hole 7 is opened on the pressure head cover 3, and lock piece 6 is sheathed in the locking hole 7.Lock piece 6 is holding screw or lock pin.An end that is connected with depression bar 1 in the pressure head cover 3 offers the ladder endoporus, and top is through hole, and the bottom is an internal thread hole, and locking hole 7 is opened on the lateral surface of through hole.In use,, offer internal thread on the pressure head cover 3,, can also after the screw thread place coats freezing plastic on the depression bar 1, be sheathed on again in the pressure head cover 3, tighten and finish connection therefore for connection stability owing to offer external thread on the depression bar 1.
The above only is a preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art in the some improvements and modifications that do not break away under the utility model principle prerequisite, for example, these improvements and modifications also should be considered as protection domain of the present utility model.
