Description
Technical field
The present invention relates to index(ing) feed technical field, be specifically related to a kind of pneumatic intermittent feeding mechanism.
Background technique
At present, index(ing) feed many employings cross groove wheel mechanism is realized.Directly be connected with the driving shaft of chain conveyor by the axle of cross groove wheel mechanism, the input shaft of cross groove wheel mechanism is driven by retarder.There is gap between the input shaft of cross groove wheel mechanism and output shaft, operationally produced vibration, impact stronger, easily cause roller pin to fracture.Cross groove wheel mechanism is a kind of mechanism that just can not run well very close to each other, and its acceleration is discontinuous in theory, larger impact force can be there is when starting, the stopping of mechanism, roller pin is caused to fracture and security incident occurs, easy damage, risk factor are high, relative production and the cost of maintenance high.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned defect, provides a kind of pneumatic intermittent feeding mechanism, and structure is simple, and cost is low, is convenient to control.
The technological scheme that the present invention solves the employing of its technical problem is as follows:
A kind of pneumatic intermittent feeding mechanism, comprise leading screw, casing, the cylinder of box house, gear, ratchet, positioning pawl, upper end is provided with wide in described casing, the fixed plate that lower end is narrow, described gear is movably connected in fixed plate upper end, fixed plate bottom is connected with the movable end being arranged on fixed plate bottom side and controlling the cylinder of fixed plate horizontal hunting, cylinder is fixed on casing, described leading screw one end is connected with gear axis, the other end extends and is provided with the feed screw nut exporting index(ing) feed outside casing, described reverse V-shaped ratchet is movably connected on fixed plate corresponding bottom gear, ratchet one end is the arc catching on pinion rotation and coordinate with gear, the other end is corresponding with the rocking bar top being arranged on ratchet bottom side downwards, rocking bar bottom is connected with cylinder movable end front end, the casing that described gear side is corresponding is also provided with the positioning pawl preventing gear from reversing, moving left and right of cylinder control link level, fixed plate bottom is connected with connecting rod front end, under the drive of connecting rod, fixed plate with leading screw place for its lower end of axle swings, ratchet simultaneously, rocking bar also swings simultaneously, the rocking bar swung to the right pushes ratchet one end, ratchet is arranged its one end coordinated with gear while swinging with fixed plate, when being moved to the left, rocking bar upper end is separated with ratchet, ratchet catches on gear, the ratchet driven gear that moves right rotates counterclockwise, positioning pawl gear keeps engagement, and gear can only be made to rotate in the counterclockwise direction, circulation like this, moment of torsion is passed to leading screw by the gear rotated, and the horizontal intermittent type finally realizing feed screw nut moves.
Further, connecting rod is provided with between described cylinder and fixed plate, connecting rod one end is connected with cylinder piston rod, the other end is flexibly connected with fixed plate bottom, connecting rod increases the swing degree of fixed plate, the amplitude that gear is rotated at every turn is large, and can be realized the distance of each intermittent feeding of each feed screw nut by control cylinder.
Further, the fixed plate that the top of falling V of described reverse V-shaped ratchet is corresponding with gear right lower side is flexibly connected.
Further, described rocking bar top is the arcuate structure with click-fit, and rocking bar bottom is connected with connecting rod, and arcuate structure is convenient to push ratchet when swinging, and makes the action pushing ratchet smooth and easy, is convenient to ratchet and arranges and catch on gear.
Further, the casing of the opposite side that described positioning pawl is relative with ratchet is flexibly connected, and is provided with the spring keeping positioning pawl and gears meshing between positioning pawl rear end and casing, and under the action of the spring, positioning pawl makes gear rotate by specific direction, can not reverse.
The invention has the beneficial effects as follows: adopt such scheme, the linear reciprocating motion of cylinder, by the cooperation of rocking bar, ratchet, gear is made to make intermittent rotary, and the intermittent feeding having the intermittent rotary of leading screw to be transformed into feed screw nut is sent to, make the workpiece that is connected with feed screw nut or a certain component do intermittent feeding and send to, structure is simple, be convenient to control, greatly reducing cost.
