Description
Technical field
The utility model relates to a kind of auxiliary support mechanism that is applied to overlength ball screw.
Background technique
Ball screw is as dirivig member, and its effect is by rotatablely moving, to be converted to straight line motion, and more straight line motion is also faster for rotational speed.In reality using process, use sometimes overlength ball screw, slenderness ratio is greater than 60, and now ball screw is because span is larger, intermediate portion can be bending sagging under Action of Gravity Field, thereby affect the critical speed of rotation of ball screw, or cause and tremble, reduce transmission accuracy.
Model utility content
The utility model is for avoiding the existing deficiency of above-mentioned prior art, a kind of overlength ball screw elastic supporting mechanism is provided, overcomes the sagging problem of large span ball screw middle bent, improve ball screw critical speed of rotation, reduction is trembled, and improves transmission accuracy.
The utility model is that technical solution problem adopts following technological scheme:
The structure characteristic of the utility model overlength ball screw elastic supporting mechanism is: in horizontal base, be and be horizontally disposed with one " T shape cavity; described "T"-shaped cavity is to consist of cross through hole and longitudinal hole; described cross through hole connects described horizontal base in both sides; one end of described longitudinal hole and described cross through hole join, the other end connects horizontal base; One bent axle is set in described cross through hole, described bent axle can rotate in described cross through hole, described bent axle stretches out also along stretching for square shaft in a side of horizontal base, on described square shaft, be fixedly installed nylon support block, described nylon support block is upright, on the described top that is upright nylon support block, be set to arc groove, ball screw is supported in described arc groove; Described bent axle is positioned on the stage casing axle of longitudinal hole position and is provided with the notch that one section of degree of depth is greater than crank throw, and described notch is connected with described longitudinal hole; In described longitudinal hole, be pressed with preloading spring, the front end of described preloading spring reaches described notch and is butted on bottom land plane, take described bottom land plane as spring seat.
The feature of the utility model overlength ball screw elastic supporting mechanism is also: at one section of sliding sleeve of front end suit of described preloading spring.
The feature of the utility model overlength ball screw elastic supporting mechanism is also: described horizontal base arranges respectively one section of bolt block at the length direction along described longitudinal hole, the afterbody of described preloading spring arranges adjusting bolt, described adjusting bolt and bolt block screw-thread fit, to regulate the pretightening force of preloading spring, and with afterbody nut check.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model is, with nylon support block, overlength ball screw is implemented to supplemental support, when worktable process nylon support block, utilizes the rotation of bent axle directly nylon support block to be pushed over; When worktable leaves nylon support block, bent axle is under the effect of external force, and its eccentric part is keeping to the trend of the direction motion of application of force opposite direction, thereby makes nylon support block recover to be upright state, again drops into the support to ball screw.The utility model has been realized the model utility object that makes overlength ball screw obtain good supplemental support, and it is simple in structure, easy to implement.
2, the utility model volume is little, highly low, can the be suitable for working platform setting height(from bottom) occasion at the end very.
3, the utility model good stability, does not need to arrange induction Detecting element, has effectively avoided the Detecting element fault of bringing that lost efficacy.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 a, Fig. 2 b are the different use of the utility model view with Fig. 2 c;
Number in the figure: 1 horizontal base, 1a cross through hole, 1b longitudinal hole, 2 bent axles, 2a square shaft, 2b notch, 2c bottom land plane, 3 nylon support blocks, 3a arc groove, 4 preloading springs, 5 sliding sleeves, 6 adjusting bolts, 7 afterbody nuts, 8 bolt blocks, 9 end caps, 10 worktable, 11 ball screws.
Embodiment
Referring to Fig. 1, in the present embodiment, the structural type of overlength ball screw elastic supporting mechanism is:
In horizontal base 1, be and be horizontally disposed with a "T"-shaped cavity, "T"-shaped cavity is to consist of cross through hole 1a and longitudinal hole 1b, cross through hole 1a connects horizontal base 1 in both sides, longitudinal hole 1b one end and cross through hole 1a join, and the other end connects horizontal base 1; One bent axle 2 is set in cross through hole 1a, bent axle 2 can rotate in cross through hole 1a, bent axle 2 stretches out also along stretching for square shaft 2a in a side of horizontal base 1, on square shaft 2a, be fixedly installed nylon support block 3, it is upright that nylon support block 3 is, on the top that is upright nylon support block 3, be set to arc groove 3a, ball screw 11 is supported in arc groove 3a; Bent axle 2 is supported by end cap 9 envelopes at the opposite side of horizontal base 1; Bent axle 2 is positioned on the stage casing axle of longitudinal hole 1b position and is provided with the notch 2b that one section of degree of depth is greater than crank throw, and notch 2b is connected with longitudinal hole 1b; In longitudinal hole 1b, be pressed with preloading spring 4, the front end of preloading spring 4 reaches notch 2b and is butted on bottom land plane 2c, take bottom land plane 2c as spring seat.
Smooth and easy in order to guarantee that preloading spring 4 slides in longitudinal hole 1b and notch 2b, the front end at preloading spring 4 in the present embodiment is set with one section of sliding sleeve 5.
For the ease of the adjustment of assembling and the pretightening force to preloading spring 4, horizontal base 1 arranges respectively one section of bolt block 8 at the length direction of through hole 1b longitudinally, the afterbody of preloading spring 4 arranges adjusting bolt 6, adjusting bolt 6 and bolt block 8 screw-thread fit, to regulate the pretightening force of preloading spring 4, and lock with afterbody nut 7.
Fig. 2 a is depicted as worktable 10 and moves from right to left, through nylon support block 3, nylon support block 3 is pushed over to the left, now, bent axle 2 turns over an angle counterclockwise, and compresses preloading spring 4 with second edge of the bottom land plane in its notch 2b, and preloading spring 4 is compressed.
Fig. 2 b is depicted as after worktable 10 leaves nylon support block 3 from right to left, due to preloading spring 4 shoring for second edge of the bottom land plane 2c of notch 2b in bent axle, bent axle 2 is turned round clockwise, and nylon support block 3 recovers to be erectility to ball screw 11 supplemental support.
Fig. 2 c is depicted as worktable 10 and moves from left to right, through nylon support block 3, nylon support block 3 is pushed over to the right, now, bent axle 2 turns over an angle clockwise, and compresses preloading spring 4 with first edge of the bottom land plane 2c in its notch 2b, makes equally preloading spring 4 be compressed.After worktable 10 leaves nylon support block 3 from left to right, because preloading spring 4 is for the shoring of first edge of the bottom land plane 2c of notch 2b in bent axle, make bent axle 2 turning anticlockwises, nylon support block 3 recovers to be erectility to ball screw supplemental support.
