Description
Technical field
The utility model relates to a kind of mechanical device, specially refers to the swing type track reproducing mechanical device.
Background technique
The frequent specified point that needs to carry out in the member is pressed the planar obit simulation curvilinear motion of a certain regulation in the design of automatic and automatic, need realize this purpose by track reproducing mechanical device.In the prior art, can realize that the cam combined mechanism has the operating rate height, advantage such as cost is low, reliable by numerical control device or cam combined mechanism.At present, the cam combined mechanism mechanical device that constitutes by the cam by two interlocks mostly is the direct-acting type sliding block type structure, has sliding friction but the shortcoming of direct-acting type sliding block type structure is inside, and it is dumb to move.
The model utility content
The purpose of this utility model provide a kind of simple in structure, swing type track reproducing mechanical device flexibly moves.
The purpose of this utility model is achieved in that
The swing type track reproducing mechanical device comprises transmission device, cam, connecting rod and fixed support, and two cams are installed on the same transmission shaft; Described connecting rod comprises that two swing connecting bar are connected connecting rod with two, two swing connecting bar, one end is respectively established a roller, the other end is fixedly connected on the described fixed support, above-mentioned roller is resisted against respectively on two cams, establish a sliding-groove on each swing connecting bar respectively, described two sliding-grooves link to each other with elastic member on being fixed in fixed support by a bolt respectively, and two connect connecting rods one end flexibly connects with two sliding-grooves respectively, and the other end interconnects by fixing bolt; This fixing bolt connects actuator.
Wherein, above-mentioned elastic member is a spring; The bolt of above-mentioned connection elastic member, sliding-groove swing connecting bar and fixed support joint and be connected connecting rod and the sliding-groove joint between; Connecting connecting rod flexibly connects by bolt and sliding-groove.
The utility model makes it compared with prior art owing to adopted above-mentioned technological scheme, has following advantage and good effect:
Make two to connect connecting rod formation triangular structure because the utility model adopts, produce track reproducing, make this mechanical device structure more simple at two places of being connected to each other that connect connecting rods; Overcome the direct-acting type sliding block type structure simultaneously and caused the inflexible shortcoming of motion because of the sliding friction of inside, make motion of mechanism flexibly, reliable.
Description of drawings
To embodiment of the present utility model and in conjunction with the description of its accompanying drawing, can further understand the purpose of this utility model, specific structural features and advantage by following.Wherein, accompanying drawing is:
Fig. 1 is the utility model Facad structure schematic representation.
Fig. 2 is the utility model plan view.
Embodiment
As Fig. 1, the utility model swing type track reproducing mechanical device shown in Figure 2, comprise transmission device 1, transmission device 1 is installed on the fixed support 2, can be gear or belt pulley, what present embodiment adopted is belt pulley, cam 31 and cam 32 back-to-back being installed in jointly on the same pto, swing connecting bar 41 1 ends are provided with a roller 411, roller 411 leans against on the cam 31, the other end is fixed on the fixed support 2 by bolt 611, swing connecting bar 41 stage casings are provided with a sliding-groove 412 along bar, spring 71 1 ends are connected with sliding-groove 412 by bolt 621, and the other end connects connecting rod 51 1 ends and is connected on the sliding-groove 412 by bolt 631 by being bolted on the fixed support 2, bolt 621 can slide arbitrarily along sliding-groove 412 between bolt 611 and bolt 631, to guarantee that roller 411 leans against on the cam 31 all the time; Corresponding, swing connecting bar 42 1 ends also are provided with a roller 421, roller 421 leans against on the cam 32, the other end is fixed on the fixed support 2 by bolt 612, a sliding-groove 422 is established along bar in swing connecting bar 42 stage casings, spring 72 1 ends are connected with sliding-groove 422 by bolt 622, the other end is by being bolted on the fixed support 2, connecting connecting rod 52 1 ends is connected on the sliding-groove 422 by bolt 632, the other end is connected to each other with being connected connecting rod 51 by fixing bolt 8, and fixing bolt 8 connects actuator.
Track for any requirement, available computers is calculated the profilogram of cam 31 and cam 32, the cam 31 that has the respective profile curve by numerical control machine tool processing place, 32, with cam 31,32 are installed in the utility model swing type track reproducing mechanical device, transmission device 1 drives pto and rotates, drive is installed in two cams 31 on the axle, 32 rotate simultaneously, by leaning against two cams 31, two rollers 411 on 32,421 with cam profile curve drive swing connecting bar 41,42 do corresponding swing, and then drive connects connecting rod 51,52 respectively along sliding-groove 412,422 slide, finally connecting two connection connecting rods 51,52 fixing bolt 8 places produce required track, and control connection is moved by this geometric locus in the actuator at fixing bolt 8 places.
When needs actuator moved according to another geometric locus, only needing to replace former cam with two cams that meet this new geometric locus can achieve the goal.
