Abstract
Provided is a slider-crank mechanism for a governor. The slider-crank mechanism for the governor is characterized by comprising a rack, a rotating shaft fixed on the rack, a first connection rod, a second connection rod, a driving friction disc and a driven friction disc. Two ends of the first connection rod are respectively hinged with the rotating shaft and the second connection rod, the first connection rod and/or the second connection are/is provided with balance weights, one end of the second connection rod is hinged with the driving friction disc, the driving friction disc is in sliding connection with the rotating shaft in an axial direction, and the driven friction disc is arranged on one side, hinged with the balance weights, of the driving friction disc. The mentioned technical scheme is characterized in that when the rotating shaft rotates, the centrifugal force generated by the balance weights drives the first connection rod and the second connection rod to pull the driving friction disc to move towards the driven friction disc, friction force gets larger with speed getting higher, the rotating speed of the rotating shaft can be well controlled not to be too high.
Description
Technical field
The utility model relates to the anchor clamps that use in a kind of machining.
Background technique
Slidercrank mechanism is a kind of mechanical structure commonly used, and it is converted into the to-and-fro motion of slide block on straight line with the rotation of crank.Governor then refers to regulate the equipment of mechanical device movement velocity.How slidercrank mechanism perfectly is used on the governor is the problem that the technician endeavours to solve always.
The model utility content
The utility model is intended to provide a kind of governor that uses slidercrank mechanism.
Governor slidercrank mechanism in this programme, it is characterized in that: comprise frame, be fixed on rotating shaft on the frame, first connecting rod, second connecting rod, initiatively grind sassafras dish and passive mill sassafras and coil, the two ends of first connecting rod are hinged with rotating shaft and second connecting rod respectively, first connecting rod and/or second connecting rod are provided with counterweight, one end of second connecting rod with initiatively grind sassafras and coil hinged, initiatively grind the sassafras dish and be in axial sliding connection with rotating shaft, passive mill sassafras dish is located at and is initiatively ground the side that the sassafras dish is hinged with counterweight.
The characteristics of technique scheme are: when rotating shaft is rotated, the centrifugal force that counterweight produces drives first connecting rod and the passive mill of sassafras dish convergence sassafras dish is initiatively ground in the second connecting rod pulling, the more fast pressure of speed is that frictional force is more big, and the rotating speed that can well control rotating shaft is unlikely too high.
Further, initiatively grind between sassafras dish and rotating shaft and be provided with stage clip, in the time of can guaranteeing that axial thrust load at counterweight centrifugal force is less than spring force, initiatively grind sassafras dish and passive mill sassafras and coil and can not produce friction, can effectively control speed limit.
Further, frame is provided with position shelf, the mode that passive mill sassafras coils to have axial translational degree of freedom connect with position shelf on, can regulate easily based on this feature and initiatively to grind the spacing that sassafras dish and passive mill sassafras are coiled, to tackle different demands.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the utility model embodiment's schematic representation.
Embodiment
As shown in Figure 1: the governor in this enforcement comprises frame 1 with slidercrank mechanism, be fixed on the rotating shaft 2 on the frame, first connecting rod 3, second connecting rod 4, initiatively grind sassafras dish 5, passive mill sassafras dish 6, the two ends of first connecting rod are hinged with rotating shaft and second connecting rod respectively, first connecting rod and second connecting rod are provided with counterweight 31, one end of second connecting rod with initiatively grind sassafras and coil hinged, initiatively grinding the sassafras dish is being in axial sliding connection with rotating shaft, initiatively grind between sassafras dish and rotating shaft and be provided with stage clip 51, frame is provided with position shelf 7, passive mill sassafras dish is threaded by screw rod 61 with position shelf, and passive mill sassafras dish is located at and is initiatively ground the side that the sassafras dish is hinged with counterweight.
The working method of present embodiment is: when rotating shaft is rotated, counterweight is got rid of outside under centrifugal action, the axial thrust load pulling that produces is initiatively ground the sassafras dish and is relied on passive mill sassafras dish, the rubbing surface that initiatively grinds between sassafras dish and passive mill sassafras dish produces braking effect, when spindle speed is lower than certain value, described axial thrust load initiatively grinds the sassafras dish and leave passive mill sassafras dish under the stage clip effect less than the elastic force of stage clip.
Above-described only is embodiment of the present utility model, and general knowledge such as known concrete structure and characteristic are not done too much description at this in the scheme.Should be understood that; for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
