Description
Technical field
The utility model belongs to the equipment technical field being exclusively used in and manufacturing discharge tube, discharge lamp and parts thereof.
Background technology
In the production field of electric light source products; the main purpose of filament tensioner is automatically tied up on the seal wire of stem stem by tungsten filament, and complete seal wire shaping on the device, cut end silk, seal wire flattening, guide wire hook, automatically go up tungsten filament, be stained with the multiple tracks such as electronic powder, upper guard ring production process.In whole process, after wherein the most important thing is tungsten filament to send into the crotch of stem stem seal wire, filament is pressed on stem stem seal wire and makes it to form one.Because filament is comparatively thin, this procedure is all adopt manual operation at present, and inefficiency, quality conformance is poor, and production cost is high.
Utility model content
The utility model is intended to the filament hold-down mechanism providing a kind of automatic impaction, operating efficiency high.
Technical scheme in this programme is: filament hold-down mechanism, comprise cylinder and compactor, this cylinder front and back end is respectively arranged with an air ports, and on the piston of cylinder interior, bias is combined with screw mandrel, the free end of screw mandrel is connected with cylinder output shaft, with card article on this cylinder output shaft; This compactor inside is provided with main shaft movable linearly, this main shaft has the groove coordinated with card article, is provided with spring between main shaft and compactor housing; Main shaft end is fixed with voussoir, and voussoir both sides are be articulated with the fork on compactor housing for a pair, are provided with pellet between fork, and fork end is provided with a pair fixture block in opposite directions.
The beneficial effect of this programme is: on piston, eccentric setting has screw mandrel, when air enters from two air ports are staggered, piston can horizontally slip in cylinder body, the movement of piston can make the screw mandrel coordinated with it rotate, because piston and rotating output shaft are eccentric settings, therefore piston can not rotate dynamic, the rotating of cylinder output shaft, and the card article on cylinder output shaft coordinates with the draw-in groove of sub-air inlet main shaft, the rotating of cylinder output shaft can drive the main shaft compressing it to move up and down, the voussoir of main shaft end during the moving up and down of main shaft also moves up and down, thus the fork opening and closing of mobile left and right, thus make the also corresponding opening and closing of the fixture block on fork end, thus the tungsten filament between fixture block is pressed on stem stem.
Further, between described screw mandrel free end and cylinder interior, be provided with thrust bearing, bear the axial thrust of screw mandrel, reduce the friction of screw mandrel, ensure the stationarity that screw mandrel rotates.
Further, described draw-in groove is and arc-shaped slot, and the top of draw-in groove is plane, make dop can not make main axle moving when draw-in groove camber line portion moves, when dop turns to plan position approach, can make main shaft moves, dop turns to camber line position during from plan position approach, main shaft moves down.
Further, the perisporium of described piston has seal groove, seal groove internal fixtion has the rubber seal of O type, improves the air-tightness of piston.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model filament hold-down mechanism embodiment;
Fig. 2 is the structural representation of cylinder in Fig. 1.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference numeral in Figure of description 1 and Fig. 2 comprises: 1-cylinder, 2-first air ports, 3-second air ports, 4-piston, 5-screw mandrel, 6-cylinder output shaft, 7-thrust bearing, 8-card article, 9-main shaft, 10-draw-in groove, 11-housing, 12-spring, 13-voussoir, 14-fork, 15-pellet, 16-fixture block.
