Abstract

The invention discloses a reciprocating motion device which is capable of easily realizing the back and forth motion of a working platform. The reciprocating motion device is characterized in that a base, a rolling wheel, a wheel shaft, a wheel arm, a movable working platform, an electric motor, an electric motor shaft, a driving chain wheel, a chain, a driven chain wheel, a chain wheel shaft and a driven wheel seat are sequentially connected, the chain is provided with a high chain board, a rotating wheel shaft is fixedly arranged on the high chain board, a rotating wheel is fixedly arranged on the rotating wheel shaft and can rotate freely, the rotating wheel is positioned in a groove of a rotating wheel fixing seat and can move vertically along the groove, and the rotating wheel fixing seat is fixedly arranged on the base. When the reciprocating motion device is in work, the electric motor drives the driving chain wheel to rotate, the movement of the high chain board is limited by the rotating wheel fixing seat, thus only the other side and the chain which is coiled on the driving chain wheel and the driven chain wheel can move, and the driving chain wheel, the driven chain wheel and the movable working platform can be driven to move; and when the rotating wheel is arranged at the outermost end of the driving chain wheel or driven chain wheel, the motion directions of the driving chain wheel and the driven chain wheel start to change, and thus the reciprocating motion of the movable working platform is realized.

Description

Reciprocator

Affiliated technical field

The present invention relates to a kind of reciprocator.

Background technique

At present, existing reciprocator mainly contains two kinds of mechanical transmission and electronic controls, although electronic control result is simple, its cost is higher, mechanically operated reciprocator, and its complex structure, manufacture difficulty and cost are all higher.

Summary of the invention

In order to overcome the defective of existing reciprocator, the invention provides a kind of reciprocator, it can be converted to the rotation of motor the to-and-fro motion of mobile work platform, and simple in structure.

The technical solution adopted for the present invention to solve the technical problems is: wheel shaft links together roller and wheel arm, the wheel arm is fixed on the below of mobile work platform, motor and driven wheel seat all are fixed on the mobile work platform, drive sprocket is fixed on the motor shaft of motor, sprocket shaft is fixed on the driven wheel seat, driven sprocket is connected with sprocket shaft and is free to rotate, be connected by chain between drive sprocket and the driven sprocket, high carrier bar is arranged in the carrier bar of chain, runner shaft is fixed on the high carrier bar, runner is connected with runner shaft and is free to rotate, and runner places in the middle groove of runner fixed base, and the runner fixed base is fixed on the base.Electric machine rotation during work, drive motor axle and drive sprocket rotate, because runner places in the groove of fixed runner fixed base, the high carrier bar of chain top can not move, therefore the chain upper section is motionless, only part and below chain movement on drive sprocket, the driven sprocket move right drive sprocket and driven sprocket simultaneously, drive mobile work platform and move right; Drive sprocket moves to high carrier bar place, high carrier bar can move around sprocket wheel, sprocket wheel continues to move right, when high carrier bar and runner arrive the high order end of drive sprocket, because runner can only move downwards in the groove of runner fixed base, so drive sprocket moving direction changes into to left movement, the moving direction of mobile work platform also changes into left; In the time of directly over drive sprocket moves to runner left, runner just limits high carrier bar and below chain movement, only has like this top chain to move left, and drive sprocket, driven sprocket and mobile work platform continue to left movement; Same when high carrier bar and runner around to the driven sprocket low order end time, drive sprocket, driven sprocket and mobile work platform moving direction change again, like this mobile work platform realization to-and-fro motion.

The invention has the beneficial effects as follows, can be when not changing the sense of rotation of motor, mobile work platform is realized to-and-fro motion, and is simple in structure.

Embodiment

In Fig. 1-3, wheel shaft 2 links together roller 1 and wheel arm 3, wheel arm 3 is fixed on the below of mobile work platform 4, mobile work platform 4 can be on base 16 flexible motion, motor 5 and driven wheel seat 15 are fixed on the mobile work platform 4, drive sprocket 7 is fixed on the motor shaft 6 of motor 5, sprocket shaft 14 is fixed on the driven wheel seat 15, but driven sprocket 13 is connected with sprocket shaft 14 and flexible rotating, be connected by chain 8 between drive sprocket 7 and the driven sprocket 13, high carrier bar 9 is arranged in the carrier bar of chain 8, runner shaft 12 is fixed on the high carrier bar 9, runner 11 is connected with runner shaft 12 and is free to rotate, and runner 11 places in the groove of runner fixed base 10 centres, and runner fixed base 10 is fixed on the base 16.

In Fig. 1, motor 5 rotates counterclockwise, runner 11 and high carrier bar 9 are positioned at the top of chain 8, because runner fixed base 10

restriction runner

11 and 9 side-to-side movements of high carrier bar, part can not be moved on the chain 8, therefore the lower part of drive sprocket 7, driven sprocket 13 and chain 8 can only move right, and drives mobile work platform 4 and moves right.

In Fig. 4, drive sprocket 7 moves to high carrier bar 9 places, high carrier bar 9 can be around drive sprocket 7 motions, drive sprocket 7 continues to move right, when high carrier bar 9 and runner 11 around to the high order end of drive sprocket 7 time, because runner 11 can only motion downwards in the groove of runner fixed base 10, so drive sprocket 7 moving direction change into left, the moving direction of mobile work platform 4 also changes into left, realizes commutation.

In Fig. 5, in the time of directly over drive sprocket 7 moves to runner 11 left, runner 11 just limits the lower componental movement of high carrier bar 9 and chain 8, only has so the upper part of chain 8 to move left, and drive sprocket 7, driven sprocket 13 and mobile work platform 4 continue to left movement.

In Fig. 6, mobile work platform 4 moves to the neutral position of runner 11 left, and continues to left movement.

In Fig. 7, driven sprocket 13 move to high carrier bar 9 and runner 11 directly over after, high carrier bar 9 and runner 11 can be around driven sprocket 13 motions, driven sprocket 13 continues to left movement, when high carrier bar 9 and runner 11 around to the low order end of driven sprocket 13 time, because of runner 11 motion that can only in the groove of runner fixed base 10, make progress, so driven sprocket 13 moving direction change into to the right, the moving direction of mobile work platform 4 also changes into to the right, realizes again commutation.

In Fig. 8, in the time of under driven sprocket 13 moves right runner 11, runner 11 just limits componental movement on high carrier bar 9 and the chain 8, only has so the lower part of chain 8 to move right, and drive sprocket 7, driven sprocket 13 and mobile work platform 4 continue to move right.
