While adopting technique scheme, when the larger side of cam radius contacts with drag link, drag link rotates around middle part, the nearly cam of drag link one end bottom, puts on the other end, and now longitudinal tie is by jack-up, longitudinal tie upper end drives on the connecting rod being attached thereto and puts, moving block turns to and is positioned at brake disc footpath upwards, and two steel locks are furthered by extension spring, and brake disc rotates.When the less side of cam radius contacts with drag link, Returnning spring drives longitudinal tie to move down, longitudinal tie upper end drives the connecting rod bottom being attached thereto, moving block outwards squeezes two steel locks that are positioned at breaker slot, steel lock and brake disc friction, thereby by brake disc stop, brake disc is fixedly connected with turntable, so can be by turntable stop.The utility model is by brake disc is fixedly connected on turntable, by steel lock control brake disc, thereby controls the rotation of turntable, and the utility model can be braked revolving table for a long time effectively.
Drag link rotates around middle part, and the nearly cam of drag link one end bottom, puts on the other end, and now longitudinal tie is by jack-up, and longitudinal tie upper end drives on the connecting rod being attached thereto and puts, and moving block turns to and is positioned at brake disc footpath upwards, and two steel locks are furthered by extension spring, and brake disc rotates
Further, described drag link contacts one end with cam and is provided with scroll wheel, and the friction between scroll wheel and cam is little, so can slow down the wearing and tearing of drag link and cam.
Further, described drag link and longitudinal tie connecting end are provided with connecting sleeve, and establish adjustment screw on the longitudinal tie of drag link both sides, so just can adjust longitudinal tie in vertical movement, while thering is no active force with guarantee moving block and steel lock, moving block is positioned at brake disc radially.
Further, the longitudinal tie of described spring lower end is provided with lock ring, increases the decrement of Returnning spring by lock ring, and Returnning spring drives the downward power of longitudinal tie to increase, larger thereby the moving block being fixedly connected with connecting rod acts on the power of steel lock, can regulating brake force.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the utility model rotary work table brake embodiment's structural representation.
Embodiment
As shown in Figure 1, a kind of rotary work table brake, comprises base, driving mechanism, driving mechanism and arrestment mechanism, and wherein, driving mechanism comprises main shaft 1 and the cam 2 being connected with main shaft 1; Driving mechanism comprises drag link 4, longitudinal tie 12, guide pin bushing 6, Returnning spring 13 and connecting rod 11, drag link 4 middle parts and base are rotationally connected, drag link 4 one end and cam 2 bottoms offset, the other end is fixedly connected with longitudinal tie 12 lower ends, guide pin bushing 6 is fixed on base, and Returnning spring 13 is sheathed on longitudinal tie 12, and upper end is connected with guide pin bushing 6, lower end is connected with longitudinal tie 12, and connecting rod 11 one end and longitudinal tie 12 upper ends are hinged; Arrestment mechanism comprises brake disc 10, moving block 7, the extension spring 9 of ring-type and coordinates the steel lock 8 of brake disc 10, brake disc 10 is fixedly connected with revolving table, brake disc 10 inner sides are along being circumferentially with breaker slot, in breaker slot, be provided with two steel locks 8 that one end is hinged, moving block 7 is positioned at breaker slot, and between two steel lock 8 free ends, extension spring 9 is located between two steel locks 8; Connecting rod 11 the other ends are fixedly connected with moving block 7 middle parts.
