Abstract
A kind of ball screw and the bindiny mechanism of worm gear, belong to punching machine technical field, and the major technique that it is used is：The blind hole with ball screw axis perpendicular is formed with the bulb section diameter maximum of ball screw, an alignment pin is fixed in described blind hole, installed on described alignment pin ledge and fix a joint ball, described joint ball is lying into breach, described breach is half-circle-arc shape, worm screw is arranged on the side of worm gear, is intermeshed between worm and gear, and whole mechanism of the invention has convenient to install and maintain and service life is higher.
Description
Technical field
The present invention relates to a kind of ball screw and the bindiny mechanism of worm gear, belong to press technologies field.
Background technology
It is known that：In some medium-and-large-sized, high-grade forcing press products, the closure of sliding block is highly adjusted and uses machine
The method of dynamic regulation, i.e., using by motor-operated worm screw, worm screw drives worm gear, worm gear to drive ball screw in connecting rod
Rotate in screw thread, the closure that adjusting slider is come with this highly, wherein in above-mentioned mechanism's connection, one and ball are bored on bulb
The perpendicular hole of captacula rod axis, and alignment pin is installed in hole, breach is provided with the edge of the endoporus of worm gear, alignment pin it is prominent
Go out position to be stuck in breach, the purpose of mutual rotation between limiting ball captacula worm and wheel is carried out with this.Alignment pin described above
It is the structure of cylinder, the breach groove profile that the edge of the endoporus of worm gear is opened, ball screw is not due to forcing press operationally
Swing with stopping, alignment pin is easily stuck in breach, cause regulation difficult, meanwhile, the corner angle of alignment pin are also easily gnawed therewith
Portion of material on the worm gear of contact, and form broken nitre and fall between ball screw and ball bowl, so as to cause between moving component
Abrasion, the service life of part is reduced, further, since the edge of the endoporus of the worm gear breach groove profile opened, pocket bottom
Wedge angle easily trigger stress concentration, cause the service life reduction of worm gear.
The content of the invention
It is an object of the invention to：The bindiny mechanism of a kind of ball screw and worm gear is provided, existing ball screw is overcome
In the bindiny mechanism of worm gear, alignment pin is easily stuck in breach, the difficult defect of the regulation for thus being triggered；Meanwhile,
It is in order in overcoming existing mechanism, the corner angle of alignment pin easily gnaw the material on the worm gear for contacting, and draw therefrom
The broken nitre of hair is fallen between bulb and ball bowl, causes the defect of the heel and toe wear between moving component, furthermore：The present invention also exists
In existing structure is overcome, the breach groove profile opened by the edge of the endoporus of worm gear, the wedge angle of pocket bottom easily triggers
Stress concentration, causes the defect of the service life reduction of worm gear.
The present invention realizes that the technical scheme that above-mentioned purpose is used is：A kind of described ball screw and the connection machine of worm gear
Structure, it includes：Ball screw（1）, worm gear（2）, alignment pin（3）, joint spheroid（4）, worm screw（5）, lower ball bowl（6）, connecting rod
（7）, upper ball bowl（8）, turbine casing（9）, gland（10）, bolt（11）, described worm gear case（9）Interstitial hole in set one
Individual lower ball bowl（6）, lower ball bowl（6）Above worm gear is installed（2）, described worm gear（2）Inner hole wall is vertically formed with half
Arc-shaped slot（12）, ball screw（1）Bulb partially pass through worm gear（2）Interstitial hole after, ball screw（1）Bulb part
It is placed in lower ball bowl（6）Ball-and-socket in, in ball screw（1）Bulb section diameter maximum be formed with and ball screw（1）Axle
The perpendicular blind hole of line, fixes an alignment pin in described blind hole（3）, installed on described alignment pin ledge and fix one
Individual joint ball（4）, described joint ball（4）It is lying into breach（12）Interior, described breach（12）It is half-circle-arc shape, worm screw
（5）Installed in worm gear（2）Side, between worm and gear be intermeshed, worm gear（2）Ball bowl is disposed with above（8）With
Gland（10）, bolt（11）By gland and worm gear case（9）Between fixed, connecting rod（7）With ball screw（1）Between by respective
Internal and external threads be connected with each other.
Beneficial effect：
Because spheroid has the universal free degree in breach, so, it is not easy to it is stuck, while also it will not be contacted zero
The phenomenon for biting is caused on part surface, thus also it is avoided that metal fragment is possible to show the heel and toe wear caused by moving component
As the service life of machinery being extended, additionally, the breach that the edge of the endoporus of worm gear is opened is circular shape, it is not easy to produce
Stress concentration, it is possible to increase the service life of worm gear.
