Abstract
The utility model discloses a chuck liquid-state sealing structure used for a circular screen printing machine. The chuck liquid-state sealing structure comprises a bearing, a bearing seat, a bushing block and a clamp ring, the bushing block is arranged under the bearing, and the clamp ring is positioned on the right side of the bearing. Two permanent magnets are arranged on opposite positions located on two sides of a fit clearance between the clamp ring and the bearing seat. Two permanent magnets are arranged on opposite positions located on two sides of a fit clearance between the bushing block and the bearing seat. Magnetic liquid is arranged between the permanent magnets for sealing. Through adoption of the magnetic liquid for sealing, the chuck liquid-state sealing structure greatly improves sealing performance, decreases torsion increase caused by a sealing piece, stops the phenomenon of a twisted net caused by static rotary torsion of a chuck, prolongs the service life which is twice as long as an original structure, and has great practical value.
Description
Technical field
The utility model belongs to field of mechanical technique, is specifically related to a kind of liquid airproof structure that is used for the circular screen printer chuck.
Background technology
In the prior art, in the net chuck that circular screen printer uses, shown in accompanying drawing 2, adopt sealing strip 1 ' or shown in accompanying drawing 3, adopt y-type seal ring 2 '; This spline structure is prone to poor sealing; Reduce service life, and can find to turn round the phenomenon of net, all wrong flower takes place or run the flower phenomenon through regular meeting inevitably; Reduced the stamp precision, product percent of pass is low.
Summary of the invention
The utility model technical problem to be solved provides a kind of chuck liquid airproof structure that overcomes above-mentioned defective.The utility model adopts following technical scheme: a kind of liquid airproof structure that is used for the circular screen printer chuck; Comprise bearing and bearing block; Be positioned at the lining of bearing below and the collar on bearing right side; Collar and bearing block all respectively are equipped with two permanent magnets on the relative position at lining and bearing block fit clearance place, and the centre is equipped with magnetic liquid and is sealed.
Because the utility model adopts magnetic fluid sealing; Improve its sealing property greatly, reduced the torsion increase that causes because of seal; Stopped to turn round the net phenomenon, made to reach the twice of original structure service life, had great practical value because of the static rotary torsion reason of chuck causes.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is a gasket structure sketch map in the prior art;
Fig. 3 is a y-type seal ring structural representation in the prior art.
The specific embodiment
As shown in Figure 1; A kind of liquid airproof structure that is used for the circular screen printer chuck; Comprise bearing 6 and bearing block 2, be positioned at the lining 3 of bearing below and the collar 1 on bearing right side, collar 1 and bearing block 2; On the relative position at lining 3 and bearing block 2 fit clearance places two permanent magnets 4 are housed respectively all, the centre is equipped with magnetic liquid 5 and is sealed.
Because the utility model adopts magnetic fluid sealing; Improve its sealing property greatly, reduced the torsion increase that causes because of seal; Stopped to turn round the net phenomenon, made to reach the twice of original structure service life, had great practical value because of the static rotary torsion reason of chuck causes.
