Abstract
The invention discloses a push-pull force overload protective device which comprises a push-pull force power source, a push-pull rod, a connecting sleeve, a housing and a locking block, wherein the push-pull force power source is fixedly connected to one end of the connecting sleeve through a first bolt; the connecting sleeve, the housing and the locking block are arranged on the push-pull rod in a sleeving mode; one end of the housing is blocked with the other end of the connecting sleeve; a mounting hole is axially formed in the housing; a rolling ball, an ejector rod, one end of which abuts against the rolling ball, and a spring, one end of which is fixed to the other end of the ejector rod are sequentially arranged in the mounting hole; the other end of the spring is fixed to the housing; one end of the ejector rod is a slope structure; the connecting sleeve is provided with a ring-shaped slot matched with the rolling ball in a radial direction; the locking block is fixedly connected to the other end of the housing by virtue of a second bolt; and the locking block is fixedly connected to the push-pull rod. The push-pull force overload protective device is simple and compact in structure, and is reasonable in design; and overload protection is formed between a working machine and a prime motor, so that safety reliability of equipment operation can be improved, and the working efficiency is also effectively improved.
Description
Technical field
The present invention relates to technical field of mechanical transmission, refer to a kind of push-pull effort overload protection arrangement particularly.
Background technique
Many machinery equipments are not transmitting torques, but transmit push-pull effort.When push-pull effort exceedes preset value, motor still runs, and is easy to a certain extent damage motor and transmission facilities.Although this embryonal structure also has overload protection, its can because of structure too complexity cause cost high, also cause limiter often to damage because driving force is excessive, the overload protection effect do not reached.
Therefore, research and develop a kind of structure simple, operate push-pull effort overload protection arrangement easily and seem necessary.
Summary of the invention
Problem to be solved by this invention will provide a kind of structure simple, compact exactly, push-pull effort overload protection arrangement reasonable in design.The de-power that this device utilizes limiter to preset, by installing non-contact limit switch, issuing a signal to control centre, then power interruptions or output unit can be made not to rerun.
For solving the problems of the technologies described above, push-pull effort overload protection arrangement designed by the present invention, comprise push-pull effort power source, pull bar, connecting sleeve, housing and locking block, push-pull effort power source is fixedly connected with one end of connecting sleeve by the first screw, connecting sleeve, housing and locking block are all set on pull bar, one end of housing engages with the other end of connecting sleeve, mounting hole is provided with vertically in housing, ball is disposed with in mounting hole, the push rod of conflicting with ball, the spring that the other end of one end and push rod is fixing, the other end of spring is fixed on housing, one end of push rod is ramp structure, connecting sleeve is disposed radially the circular groove with ball engagement, locking block is fixedly connected with the other end of housing by the second screw, locking block is fixedly connected with pull bar.
Preferably, locking block is fixedly connected with pull bar by lock screw.
Push-pull effort overload protection arrangement is the device with axial load overload protection, once overload appears in the thrust of axis or pulling force, push-and-pull force-limiting device is thrown off immediately, disconnects power by sensor.When axial over power off-load or when dropping to below setting value; push-and-pull force-limiting device automatically reverts to overload protection state; can normal delivery axial force, thus protect machinery and equipment and do not damage because of overload, be usually used in the overload protection occasion of cam follower mechanism, crank mechanism.
Advantage of the present invention is mainly reflected in following several respects:
One, structure is simple, compact, reasonable in design;
Its two, the present invention forms overload protection between working machine and prime mover, when breaking down, can not cause the damage of element particularly motor, need not change frequent easily damaged parts;
Its three, both can improve equipment run safety reliability, effectively improve working efficiency again;
Its four, easy installation and removal, cost is low, once overload is eliminated, ball resets, and makes machine and prime mover recovers again to run well.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: push-pull effort power source 1; Pull bar 2; Housing 3; Ball 4; Push rod 5; Locking block 6; Connecting sleeve 7; Lock screw 8; Spring 9; Second screw 10; First screw 11; Circular groove 12; Mounting hole 13.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but this embodiment should not be construed limitation of the present invention.
A kind of push-pull effort overload protection arrangement shown in figure, comprise push-pull effort power source 1, pull bar 2, connecting sleeve 7, housing 3 and locking block 6, push-pull effort power source 1 is fixedly connected with one end of connecting sleeve 7 by the first screw 11, connecting sleeve 7, housing 3 and locking block 6 are all set on pull bar 2, one end of housing 3 engages with the other end of connecting sleeve 7, mounting hole 13 is provided with vertically in housing 3, ball 4 is disposed with in mounting hole 13, the push rod 5 that one end and ball 4 are conflicted, with the spring 9 that the other end of push rod 5 is fixing, the other end of spring 9 is fixed on housing 3, one end of push rod 5 is ramp structure, connecting sleeve 7 is disposed radially the circular groove 12 coordinated with ball 4, locking block 6 is fixedly connected with the other end of housing 3 by the second screw 10, locking block 6 is fixedly connected with pull bar 2 by lock screw 8.
The present invention selects spring size by the axial moment of push-pull effort power source, utilize the push-pull effort upper limit of translational forces, ball 4 is made to carry out locking or sliding in thrust overload protective device, thus realize realizing equipment failure-free operation being less than power source rated moment, when power source exceedes rated moment, ball 4 is utilized to slide, realize thrust overload protective device and pull bar departs from instantaneously, signal passes to servo-system, motor power-off, realize forming overload protection between working machine and prime mover, once overload is eliminated, ball 4 resets, use formula makes machine and prime mover recovers again to run well.
When the present invention works, before the mounting, first according to the push-pull effort requirement of working machine, realized slip and the locking of ball 4 by the decrement changing spring 9.When push-pull effort power source exceedes specified push-pull effort, ball 4 presses push rod 5, thus spring 9 is compressed, and ball 4 skids off circular groove 12, and connecting sleeve 7 is thrown off, and sends a signal to control system, equipment downtime.Once overload is eliminated, ball 4 resets, and thrust overload protective device is connected with pull bar 2, makes working machine and prime mover recover again to run well.
The content be not described in detail in this specification, belongs to the known prior art of those skilled in the art.
