Description
Technical field
The utility model relates to the adjustable lifting mechanism of a kind of hoisting force.
Background technology
The lifting of workpiece on automatic production lines need adopt lifting mechanism, existing lifting mechanism normally power drives chain gear to realize lifting, specifically will the elevating bracket of workpiece be settled to be fixed on chain, elevating bracket is led at vertical direction, by the lifting conveying realizing workpiece that pumps of chain.The weak point that above-mentioned lifting mechanism exists is: the size of the power of output cannot regulate, and therefore cannot promote the workpiece exceeding the weight that it bears, and uses limitation large.
Utility model content
The utility model is intended to the lifting mechanism providing a kind of hoisting force adjustable, the problem that the power output existed to solve existing Universal lifting mechanism cannot regulate.
The lifting mechanism that hoisting force in this programme is adjustable, comprise the pedestal of frame-type, the inner side of the underframe of pedestal is provided with the slide that can slide along underframe length direction, slide is connected with a threads of lead screw, leading screw passes the side frame of pedestal and is threaded with side frame, the end of leading screw is provided with handle, slide is also hinged with the lever that can swing up and down, the lower end of one end of lever and a vertical connecting rod by the bar hole be arranged on lever and the latch inserted in bar hole hinged, connecting rod can be pumped by the effect of cam, the other end of lever and the lower end of a lifting bar hinged, lifting bar is through the first pilot hole of the top frame of pedestal, the upper end of lifting bar is fixed with the elevating bracket for settling workpiece, stage clip is provided with between the lower end and underframe of connecting rod.
Principle of work and the effect of this programme are as follows: workpiece prevents on elevating bracket, cam rotate, when cam convex surface down time, the downward vertical motion of connecting rod will be forced, thus make one end bottom of lever, the other end of lever will be put, drive lifting bar rises, thus lifting workpieces, after being taken out by the workpiece promoted, cam is rotated further, when convex surface gradually upward time, reset at the effect lower link of stage clip, thus lifting bar declined, repeat above-mentioned action, can promote next time.
This programme utilizes handle rotational lead screw, can change the position of slide, namely changes the ratio at throw of lever two ends, thus changes the power of whole mechanism lift side output and the distance of lifting, because hoisting force changes, therefore can promote the workpiece of Different Weight, practical strong.
Further, connecting rod through second pilot hole of top frame of pedestal, connecting rod be circumferentially with can with the lateral surface of top frame offset for spacing stop collar.Second pilot hole plays the effect of guiding to connecting rod, and stop collar plays spacing effect to connecting rod.
Further, the upper end of connecting rod is provided with a roller, and the cylindrical of roller and the shape face of cam offset.By arranging roller, interlinking lever end is avoided directly to contact with cam-shaped face, easily the problem of wearing and tearing connecting rod and cam.
Further, underframe is provided with guide rail, guide rail comprises base plate and is arranged on the baffle plate of base plate both sides, and slide is positioned on base plate and by the baffle plate of both sides and leads.Guide rail plays the effect of guiding to slide when slide moves.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: cam 1, roller 2, stop collar 3, leading screw 4, handle 5, connecting rod 6, spherical hinge 7, slide 8, lever 9, lifting bar 10, cushion block 11.
Embodiment is substantially as shown in Figure 1: the lifting mechanism that the present embodiment hoisting force is adjustable comprises pedestal, and pedestal is frame-type, is namely made up of underframe, two side frames and top frame.The inner side of underframe is detachably provided with guide rail by screw, and guide rail comprises base plate and is arranged on the baffle plate of base plate both sides.
Slide 8 is positioned on base plate and by the baffle plate of both sides and leads, slide 8 is hinged with the lever 9 that can swing up and down, one end of lever 9 and the lower end of vertical connecting rod 6 by the bar hole be arranged on lever 9 and the latch inserted in bar hole hinged, between the lower end and underframe of connecting rod, be provided with stage clip (not shown).Connecting rod 6 through the second pilot hole of the top frame of pedestal, connecting rod 6 be circumferentially with can with the lateral surface of top frame offset for spacing stop collar 3.The upper end of connecting rod 6 is provided with roller 2, and the cylindrical of roller 2 and the shape face of cam 1 offset, and cam 1 is driven by power and rotates.
The other end of lever 9 and the lower end of lifting bar 10 hinged, lifting bar 10 is through the first pilot hole of the top frame of pedestal, lifting bar 10 is provided with cushion block 11, cushion block 11 offsets with the lateral surface of top frame, further lifting bar is played to the effect of guiding, the upper end of lifting bar is fixed with the elevating bracket for settling workpiece.
Slide 8 is threaded with leading screw 4, and leading screw 4 passes the side frame of pedestal and is threaded with side frame, and the end of leading screw is provided with handle 5.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in specification sheets etc. record the content that may be used for explaining claim.
