Description
Technical field
The utility model relates to a kind of lifting table, especially relates to a kind of electronic controlled self-locking lifting table.
Background technology
The hydraulic elevating platform that uses drives lifting platform by hydraulic cylinder piston rod at present.Owing to adopted hydraulic efficiency pressure system, its lifting accuracy control difficulty and hydraulic efficiency pressure system require the accuracy of manufacture height, maintenance difficult, and rising or falling speed is slow.For the occasion that requires lifting automation control, for example goods transports between the flow production line diff-H especially; Material loading, roll off the production line; Regulate the workpiece height during workpiece assembling; The feeding of eminence feeder; Parts lifting during the main equipment assembling; Heavy duty machine tools material loading, blanking etc., hydraulic elevating platform has also all limited the widespread use of these lifting tables owing to do not have the overload auto-lock function and outage rear platform automatic lifting position maintenance function.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of electronic controlled self-locking lifting table that can realize the lifting accuracy control and have the safe self-locking defencive function.
Technical problem to be solved in the utility model is achieved by the following technical solution: it comprises AC servo motor, driving system and jacking system composition, described driving system is made up of harmonic speed reducer, worm-and-wheel gear, spur wheel and tooth bar, wherein the worm shaft of worm-and-wheel gear is captiveed joint with the output shaft of harmonic speed reducer, the worm-wheel shaft two ends link with spur wheel respectively, and spur wheel and tooth bar link.
Jacking system described in the utility model is made up of slide bar, connecting rod fold mechanism and upper mounting plate, and wherein the leading section of slide bar and tooth bar is hinged, and connecting rod fold mechanism and slide bar are hinged.
The structure that the utility model adopts by the control to AC servo motor, can realize the accuracy control of lifting position, speed; Owing to adopted the worm and gear transmission, can realize overload protection and cut off self-lock; Owing to adopt the connecting rod fold mechanism, make lifting action steadily reliable.
Description of drawings
The utility model is further described below in conjunction with accompanying drawing:
Accompanying drawing is depicted as structural representation of the present utility model
The specific embodiment
By accompanying drawing as can be known, this electronic controlled self-locking lifting table comprises AC servo motor 1, driving system and jacking system composition, AC servo motor 1 is captiveed joint with lower platform 10, the prime power of lifting platform is provided, described driving system is made up of harmonic speed reducer 9, worm-and-wheel gear 7, spur wheel 3 and tooth bar 2, wherein the worm shaft of worm-and-wheel gear 7 is captiveed joint with the output shaft of harmonic speed reducer 9, the worm-wheel shaft two ends link with spur wheel 3 respectively, and spur wheel 3 links with tooth bar 2.AC servo motor 1 is by behind the harmonic speed reducer 9, finishing one-level slows down, the high rotating speed of AC servo motor 1 is significantly reduced, utilize worm-and-wheel gear 7 further to slow down, the rotating speed that worm-wheel shaft 8 has obtained bigger output torque and has been fit to has been finished the space break-in of transmission simultaneously.Spur wheel 3 is formed rack and pinion drive mechanism with tooth bar 2, the straight line that is converted into tooth bar 2 is exported in the rotation of worm-wheel shaft 8 moved output.Described jacking system is made up of slide bar 6, connecting rod fold mechanism 5 and upper mounting plate 4, and wherein slide bar 6 is hinged with the leading section of tooth bar 2, and connecting rod fold mechanism 5 is hinged with slide bar 6.Drive slide bar 6 by tooth bar 2 like this and in the chute of lower platform 10, move, make and 5 actions of connecting rod fold mechanism realized the dipping and heaving of upper mounting plate (4).
The utility model can be realized the corresponding one by one of upper mounting plate displacement and motor angular transposition, that is:
H: upper mounting plate displacement
M: the folding number of plies of connecting rod fold mechanism, the number of plies is 2 in this model.
L: the length of connecting rod in the connecting rod fold mechanism
l
0: the initial length of span of connecting rod fold mechanism
θ: motor angle displacement
R: spur wheel pitch radius
i
1: the reduction ratio of harmonic speed reducer
i
2: the worm-and-wheel gear reduction ratio
Therefore can determine the motor angular transposition according to adjustable height, the completing place revertive control can be determined adjustable height according to the motor angular transposition again, the control of completing place forward.In like manner, also can realize the accuracy control of rising or falling speed.
In actual applications, when the load of upper mounting plate surpasses the load-carrying capacity of motor, if mechanism does not have the self-lock protection ability; upper mounting plate meeting get out of hand collapses and falls; light then may cause the damage of device, influence electrical machinery life, heavy then also may bring personal injury to operating personal.The utility model is owing to used worm-and-wheel gear in powerdriven process; make device have the safe self-locking defencive function; promptly when overload situations takes place; worm-gear driven not worm screw; entire mechanism is in locking state; at this moment can alleviate in the load-carrying capacity scope that upper mounting plate loads to motor, integral lifting platform can recover normal operation.In addition; some situation needs lifting table to keep a period of time at a certain adjustable height; under this situation; in order to save electric energy and protection motor; this device can allow motor cut off the power supply; though platform has temporarily lost motor-driven power, worm-and-wheel gear is in self-locking state, makes platform and integrally can keep former lifting position constant.Behind electrical power, platform can recover elevating function.
