Utility model content
For the above-mentioned problems in the prior art, a kind of function of being intended to realize that stroke amplifies, knot are now provided Structure is succinctly reasonable, and circular motion conversion, through gathering, has been in straight reciprocating motion, and can conveniently be controlled by motor by part Make the position of motion.
Concrete technical scheme is as follows:
A kind of reciprocating mechanism with stroke enlarging function, applied on automatic production line, including is fixedly mounted with respectively Crank in the motor on production line and the first rack, the shaft end for the output shaft for being connected to motor, the connecting rod being hinged with crank, The second rack directly over the first rack, and multiple gears, all teeth are provided between the first rack and the second rack Wheel is rotatably installed on a movable plate, and the one end of connecting rod away from crank is hinged with movable plate, and each gear is distinguished Engagement the first rack of connection and the second rack.
Preferably, the first rack and the second rack is parallel to each other and the gear teeth are relative.
Preferably, motor is horizontally disposed, and the horizontal plane where the output shaft of motor and the level where the center of gear Face is highly identical.
Preferably, the quantity of gear is two.
Preferably, connecting rod is located between two gears by a hinge movable plate, and pin joint.
Preferably, motor is servomotor.
The beneficial effect of above-mentioned technical proposal is:
Reciprocating mechanism with stroke enlarging function, applied on automatic production line, including is installed in life respectively Motor and the first rack in producing line, be connected to motor output shaft shaft end crank, be hinged with crank connecting rod, be located at The second rack directly over first rack, and multiple gears are provided between the first rack and the second rack, all gears are equal Rotatably it is installed on a movable plate, the one end of connecting rod away from crank is hinged with movable plate, and each gear is engaged respectively Connect the first rack and the second rack.So as to realize the function of stroke amplification, the move distance of the second rack linear movement It is four times of crank length, simple for structure reasonable, circular motion conversion, through gathering, has been in straight reciprocating motion, and pass through by part Motor can conveniently control the position of motion.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram for the reciprocating mechanism that the utility model has stroke enlarging function;
Fig. 2 is the positive structure schematic for the reciprocating mechanism that the utility model has stroke enlarging function.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, with The reciprocating mechanism with stroke enlarging function that lower embodiment combination accompanying drawing 1 and Fig. 2 are provided the utility model makees specific Illustrate.
Refering to Fig. 1, for the dimensional structure diagram of the reciprocating mechanism with stroke enlarging function;With reference to Fig. 2, for tool There is the positive structure schematic of the reciprocating mechanism of stroke enlarging function.And be the architectural feature of clear display the present embodiment, Part-structure is omitted and shown in figure.As shown in Figures 1 and 2, what the utility model was provided has the reciprocal of stroke enlarging function Motion is applied on automatic production line, and it includes the rack 1 of motor 2 and first, the connection being installed in respectively on production line Crank 3, the connecting rod 4 being hinged with crank 3, the second tooth directly over the first rack 1 in the shaft end of the output shaft of motor 2 Multiple gears 5 are provided between bar 7, and the first rack 1 and the second rack 7, all gears 5 are rotatably installed on a shifting On dynamic plate 8, the one end of connecting rod 4 away from crank 3 is hinged with movable plate 8, and each gear 5 engages the first rack 1 of connection respectively With the second rack 7.
In a preferred embodiment, the first rack 1 and the second rack 7 is parallel to each other and the gear teeth are relative.Further , motor 2 is horizontally disposed with, and the horizontal plane where the output shaft of motor 2 and the elevation of water phase where the center of gear 5 Together.
As further preferred embodiment, the quantity of gear 5 is two.Further, connecting rod 4 passes through a bearing pin 6 Movable plate 8 is hinged, and pin joint is located between two gears 5.Further, crank 3 is hinged and connected with connecting rod 4 by rotating shaft. Further, motor 2 is servomotor.
In a particular application, the rack 1 of motor 2 and first is fixed on a production line, and the rotation of the axle of motor 2 drives crank 3, connected Bar 4 is moved, and because movable plate 8 is limited between two racks by two gears 5, and then movable plate 8 is moved horizontally, while two gears 5 rotate on the first rack 1, and drive the movement of the horizontal reciprocating of the second rack 7.And the fortune of the horizontal reciprocating of the second rack 7 movement Dynamic distance is four times of the length of crank 3.Specifically, as shown in 2, the stroke of the second rack 7 linear motion it is most left and most right The limit be clearly when crank 3 is horizontal to the left and to the right on two positions, then in rotation process, crank 3 The ultimate range moved in head end horizontal direction is the distance of twice crank 3, and in the process, movable plate 8 is moved horizontally Same distance, then gear 5 have rotated isometric distance, and the second rack 7 is driven by gear 5, in gear 5 in the first rack After the distance that equivalent has been moved horizontally on 1, the second rack 7 further moves the distance of equivalent, on the whole, and the second rack 7 is straight The move distance of line movement is four times of the length of crank 3, it is achieved thereby that the function of stroke amplification, simple for structure reasonable, part It has been in straight reciprocating motion by circular motion conversion through gathering, and the position that can conveniently control to move by motor 2.
Preferred embodiment of the present utility model is the foregoing is only, is merely illustrative for the utility model, and It is nonrestrictive.Those skilled in the art understanding, can be to it in the spirit and scope that the utility model claim is limited Many changes are carried out, are changed, in addition it is equivalent, but fall within protection domain of the present utility model.
