Abstract
The utility model relates to a single-stage height adjusting cushion block, which comprises a spiral rotating body with one end equipped with threads. The threaded end of the spiral rotating body is equipped with a threaded cushion block, the non-threaded end of the spiral rotating body is anti-thrust axially and is rotationally equipped with a columnar cushion block, the outer end of the columnar cushion block is exposed on the outer side of the spiral rotating body, and the inner end of the columnar cushion block is fixedly equipped with an anti-revolving rod which is in sliding and anti-revolving connection with the threaded cushion block. The single-stage height adjusting cushion block can realize stepless height adjusting, is compact in structure and can be used in a narrow and small space.
Description
Technical field
The utility model relates to a kind of single-stage and heightens cushion block.
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 electrodeless 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 single-stage and heightens cushion block, can heighten the problem that cushion block can not use in order to solve to have now in small space.
For achieving the above object, the utility model adopts following technical scheme: single-stage is heightened cushion block, this cushion block comprises that an end is provided with the spiral pivot of screw thread, the spiral pivot end of thread is equipped with the screw thread cushion block, non-threaded end axial thrust is rotatably equipped with the cylindricality cushion block, the outer end of cylindricality cushion block is exposed to the spiral pivot outside, and cylindricality cushion block the inner is installed with the slip of screw thread cushion block only revolves the swing arm that ends that links together.
The side face of described cylindricality cushion block is provided with annular groove, and the top wire hole that spiral pivot is provided with radially reaches the wherein corresponding jackscrew of the annular groove with the cylindricality cushion block of inserting.
Be respectively equipped with the supplemental support installing hole on the outer face of described screw thread cushion block and cylindricality cushion block.
By the supplemental support installing hole supplemental support is installed on the described screw thread cushion block.
Described supplemental support is V-block, conical blocks, three-jaw supports or the supplemental support piece of other structure.
The cushion block of such scheme uses the mode of spiral to carry out height and regulates, because the characteristics of helical structure self, its radial dimension is its key dimension, and its radial dimension can be far smaller than axial dimension under the situation of requirement of strength satisfying, and therefore can use in narrow space.Be fixed with only swing arm on the cylindricality cushion block, ending swing arm slides and ends spinning and be assigned in ending in the swing arm slideway of being provided with on the screw thread cushion block, end and to have only relative sliding motion between swing arm and the screw thread cushion block and do not have relative rotational motion, guaranteed that like this cylindricality cushion block has identical angle variation when rotating with respect to spiral pivot with the screw thread cushion block.
The side face of cylindricality cushion block is provided with annular groove, the spiral rotary body is provided with the top wire hole corresponding with the annular groove position, be provided with jackscrew in the top wire hole, the end of the end of thread of jackscrew is positioned at annular groove, jackscrew has limited the axially-movable of cylindricality cushion block like this, be in when screwing state when jackscrew in addition, the end of jackscrew presses closer the bottom in annular groove, limited the rotation of cylindricality cushion block, because the rotation that has cylindricality cushion block and screw thread cushion block of trace is synchronous, also limit simultaneously the rotation of screw thread cushion block, played the effect of loosening.One end of screw thread cushion block is provided with the supplemental support installing hole, requires to install different supplemental support according to different supports like this and satisfies different needs, and supplemental support can be V-block, conical blocks, three-jaw supports or the supplemental support piece of other structure.
