Abstract
The utility model relates to a stepless height adjusting support, which comprises a spiral rotating body with two ends respectively equipped with leftward screwing thread and rightward screwing thread. Two ends of spiral rotating body are respectively equipped with a leftward screwing threaded cushion block and a rightward screwing threaded cushion block engaged with the same, and a synchronizer which enables the leftward screwing cushion block and the rightward screwing cushion block to synchronously rotate relative to the spiral rotating body is arranged between the leftward screwing threaded cushion block and the rightward screwing threaded cushion block. Because of the synchronizer, when rotating the spiral rotating body, the leftward screwing threaded cushion block and the rightward screwing threaded cushion block can be guaranteed to simultaneously inwardly or outwardly move along an axial line. According to different supporting requirements, the leftward screwing threaded cushion block and the rightward screwing threaded cushion block are equipped with different auxiliary exceeding supports, thereby expanding application range of the height adjusting cushion block. When utilizing a spiral structure to realize stepless height adjusting, the stepless height adjusting support is relatively compact in structure and can be conveniently used in a narrow and small space, for the spiral structure only shifts axially.
Description
Technical field
The utility model relates to a kind of stepless support of heightening.
Background technology
Chinese patent specification CN200620146897.X discloses a kind of machining with heightening cushion block, and this can heighten the structure that cushion block adopts parallelogram, and the angle locking device is installed between at least one group of adjacent side.Unclamp locking device during use earlier, lock again when waiting to be adjusted to suitable height.Though can heightening cushion block, this can reach the stepless effect of heightening, but, since the restriction of the design feature of parallel-crank mechanism own, the displacement about also having when heightening down in realization, therefore used space is bigger, can not use in narrow space.
The utility model content
The purpose of this utility model provides a kind of diverse in function, applied widely, compact conformation steplessly heightens support.
For achieving the above object, the utility model adopts following technical scheme: steplessly heighten support, this support comprises that two ends are respectively the spiral pivot of left and right rotation direction screw thread, the two ends of described spiral pivot are separately installed with the left and right hand thread cushion block that cooperates with it, are provided with between the left and right hand thread cushion block and make the sychronisation of left and right hand thread cushion block with respect to the synchronous rotation of spiral pivot.
Described sychronisation comprises that the swing arm that ends that is fixedly arranged on left hand thread cushion block one end face only revolves the hole on right-handed thread cushion block one end face with being arranged at, and ends swing arm and only revolves slidable fit in only revolving in the hole.
Described sychronisation comprises trace, and slidable fit is only revolved together with the left and right hand thread cushion block respectively in the two ends of trace.
One end of described spiral pivot is provided with the radial direction top thread hole, and jackscrew is installed in the top wire hole.
Be respectively equipped with the supplemental support installing hole on the end face of described left and right hand thread cushion block outer end.
Auxiliary transition is installed in the described supplemental support installing hole to be supported.
Described auxiliary transition is supported for V-block, conical blocks, three-jaw supports or the cushion block of other structure.
The stepless two ends of heightening its spiral pivot of support of such scheme are respectively equipped with the screw thread of left and right rotation direction, the left and right hand thread cushion block is assembled on the spiral pivot by the mode of screw thread respectively, rotate spiral pivot during use, because the thread rotary orientation at spiral pivot two ends is opposite, then the left and right hand thread cushion block is along the axis of spiral pivot rectilinear motion in the opposite direction, this has utilized the mechanical feature of spiral way self, when regulating height, only on the straight line direction, produce displacement, can in narrow space, use.A left side, be provided with between the right-handed thread cushion block and make a left side, the right-handed thread cushion block is with respect to the sychronisation of the synchronous rotation of spiral pivot, owing to be provided with sychronisation, a left side, have only the motion mode of relative slip between the right-handed thread cushion block and do not have motion mode in relative rotation, left side when spiral pivot rotates like this, the right-handed thread cushion block has identical straight-line displacement with respect to spiral pivot, avoided a left side, the right-handed thread cushion block screw thread cushion block occurs because the anglec of rotation is different and has screwed out spiral pivot, and another screw thread cushion block does not also produce the generation of the situation of displacement with respect to spiral pivot.
One end of spiral pivot is provided with the radial direction top thread hole, and jackscrew is installed in the top wire hole.Screw jackscrew after highly setting up, jackscrew presses closer on left hand thread cushion block or right-handed thread cushion block, can prevent that this from steplessly heightening the phenomenon that support is become flexible because of the appearance of reasons such as vibration.
Another one of the present utility model is improved, and is provided with the supplemental support installing hole on an end face of left and right hand thread cushion block, and this hole can be screwed hole or unthreaded hole.The difference that requires can be installed and used V-block, conical blocks by this installing hole, three-jaw supports or the supplemental support piece of other structure satisfies multiple support requirement, has enriched the purposes of this cushion block according to supporting.
