Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Figure 1-4, automatic thread dismantling device of the present utility model comprises the motor 2 with AC220V or DC24V two kinds of modes be fixed on motor support base 1, the power transmission shaft 3 be in transmission connection with the output of described motor 2, be arranged on end part of driving shaft in order to clamp the swivel joint 4 of screw end, the connecting plate 5 on described power transmission shaft 3 can be set in relatively up or down, guide post 6 is provided with between described connecting plate and described motor support base, described guide post upper end is fixedly connected with described connecting plate, lower end is passed described motor support base and afterbody is provided with spring (not shown).Described swivel joint can change the swivel joint of different model according to the screw of different model, facilitate screw dismounting.
Namely, described motor 2 is connected by shaft coupling with described power transmission shaft by reducing gear, preferably, the vertical plate that described motor support base comprises upper plate and lower plate and is connected with lower plate by described upper plate, described motor is preferably fixed in lower plate, described power transmission shaft through described motor support base upper plate and be provided with thrust bearing therebetween to retrain it, avoid left and right eccentric phenomena when power transmission shaft rotates.Described guide post lower end is passed the linear bearing in described upper plate or lower plate and guide post afterbody and motor support base is provided with spring, namely, the relatively described connecting plate such as described motor, power transmission shaft can be arranged on connecting plate movably forward and backward, and described connecting plate can be connected to carry out entirety and locate or the operation such as movement with exterior mechanical.
The utility model by motor and power transmission shaft and swivel joint integrally relative connecting plate can move forward and backward setting, utilize spring flexible come the precession of attachment screw or back-out, eliminate slide unit to arrange, decrease manual operation, achieve automatic dismantling, overall structure is reliability and durability, good looking appearance, have lightweight, the features such as volume is little.
Further, take off during for ease of screw is threaded off or give when installing initial screw inside extruding force, the push pedal 8 driven by linear drive apparatus 7 is provided with in described motor side, described linear drive apparatus is preferably by the hard-wired electric push rod of base or cylinder, described base is guaranteed that linear drive apparatus is stable in the stationary state and is moved radially, described push pedal upwards can connecting plate described in ejection, can extrude described motor support base downwards, two motions all can play the effect of Compress Spring.
Specifically, because connecting plate is fixedly connected with exterior mechanical, the relative stationary state in its position, when needs mounting screw, linear drive apparatus protrudes upward, push pedal is made to promote connecting plate, then by being slidably matched between connecting plate and power transmission shaft, achieve the precommpression of spring, after screw aimed at by screw, linear drive apparatus drives push pedal to return, extruding force inside when the pre-pressing force of spring ensures mounting screw.When needs knockout screw, push pedal is in room, do not interfere with push pedal or motor cabinet, the nut portion that screw pushed down by swivel joint carries out rotation dismounting, and connecting plate keeps fixing equally, along with the back-out meeting progressively Compress Spring of screw, after threading off completely, linear drive apparatus is retracted through push pedal further drive motor bearing Compress Spring, screw is taken out completely from screw, completes dismounting.
Further, for improving the integraty of product, described connecting plate being provided with the guide rod 9 guiding described push pedal to move up and down, described push pedal is provided with the linear bearing corresponding with described guide rod or pilot hole, guide pad etc.
Reveal for avoiding the fluid in screw and pollute, swab case 10 is also fixedly installed at described end part of driving shaft, swab case can according to the one of the most applicable equipment of equipment performance apolegamy different from service condition, replaceable and expansion, preferably, described swab case is formed on described connecting plate, described connecting plate is fixedly installed the slipper seal cover 11 that the power transmission shaft described in permission passes, namely on described connecting plate, side plate is provided with to form swab case, slipper seal cover serves the effect of sealing to liquid, O type circle is equipped with in inside, rubber blanket is equipped with in below.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
