Abstract
A sleeve for mounting/dismounting hexagon head bolt comprises a sleeve, wherein the sleeve inside comprises planar force transmission throw walls and stress reducing arc cylindrical surfaces; the planar force transmission throw walls and the stress reducing arc cylindrical surfaces can be arranged as six or twelve each. In the section of the sleeve, the widths of all the planar force transmission throw walls are equal, and every two adjacent planar force transmission throw walls are connected with each other through the stress reducing arc cylindrical surfaces. S is set as the distance between two planar force transmission throw walls, and when the planar force transmission throw walls and the stress reducing arc cylindrical surfaces are arranged as six each, the radius of the stress reducing arc cylindrical surfaces is between 0.1S and 0.12S; when the planar force transmission throw walls and the stress reducing arc cylindrical surfaces are arranged as twelve each, the radius of the stress reducing arc cylindrical surfaces is between 0.077S and 0.082S. The utility model adopts the stress reducing arc cylindrical surfaces, which can prevent the connecting part between the planes in the inner wall of the sleeve from be damaged by the stress, and improves the life-span of the sleeve.
Description
Technical field:
The utility model relates to a kind of instrument that is used to install and remove hex bolts, particularly a kind of sleeve that is used to install and remove hex bolts.
Background technology:
The sleeve that is used to install and remove hex bolts of the prior art, its sleeve cross section is regular hexagon or two regular hexagon.
Summary of the invention:
Technical problem to be solved in the utility model is: because the cross section that is used to install and remove the sleeve of hex bolts of the prior art is regular hexagon or two regular hexagon, in use, the drift angle place of the regular hexagon in the sleeve cross section or two regular hexagons can produce very big stress, tend to surpass the fatigue limit of bush material, cause sleeve to damage, the service life of sleeve is short.The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to provide a kind of sleeve that is used to install and remove hex bolts, the described this sleeve that is used to install and remove hex bolts has comprised a sleeve, comprise in the described sleeve that the plane power transmission pulls wall and subtract stress circle arc column face, the power transmission of described plane is pulled wall and is subtracted stress circle arc column face and can be made as each 6 or 12, in the cross section of described sleeve, the width that wall is pulled in all plane power transmissions equates, every adjacent two plane power transmissions are pulled between the wall and are connected with the described stress circle arc column face that subtracts, if being relative two plane power transmissions, S pulls the distance between the wall, pull wall and subtract stress circle arc column face when the power transmission of described plane and be made as each 6 the time, the described radius that subtracts stress circle arc column face at 0.1S between the 0.12S, pull wall and subtract stress circle arc column face when the power transmission of described plane and be made as each 12 the time, the described radius that subtracts stress circle arc column face at 0.077S between the 0.082S.The utility model and prior art contrast are pulled wall and are subtracted stress circle arc column face because comprise the plane power transmission in the sleeve, so can prevent the destruction of stress to the junction on plane in the sleeve lining and plane, improve the service life of sleeve.
Description of drawings:
Fig. 1 is a kind of schematic diagram that is used to install and remove the sleeve of hex bolts of the utility model.
Fig. 2 a kind ofly in the utility model has the schematic diagram of embodiment that the sleeve of wall is pulled in 6 plane power transmissions.
Fig. 3 a kind ofly in the utility model has the schematic diagram of embodiment that the sleeve of wall is pulled in 12 plane power transmissions.
The specific embodiment:
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of sleeve that is used to install and remove hex bolts of the utility model, comprised a sleeve, comprise in the described sleeve that the plane power transmission pulls wall 1 and subtract stress circle arc column face 2, the power transmission of described plane is pulled wall 1 and is subtracted stress circle arc column face 2 and can be made as each 6 or 12, in the cross section of described sleeve, the width that wall 1 is pulled in all plane power transmissions equates, every adjacent two plane power transmissions are pulled between the wall 1 and are connected with the described stress circle arc column face 2 that subtracts, if being relative two plane power transmissions, S pulls the distance between the wall 1, as shown in Figure 2, when the power transmission of described plane is pulled wall 1 and subtracted stress circle arc column face 2 when being made as each 6, the described radius that subtracts stress circle arc column face 2 at 0.1S between the 0.12S, as shown in Figure 3, when the power transmission of described plane is pulled wall 1 and is subtracted stress circle arc column face 2 when being made as each 12, the described radius that subtracts stress circle arc column face 2 at 0.077S between the 0.082S.
Claims (3)
1, a kind of sleeve that is used to install and remove hex bolts, include a sleeve, it is characterized in that: comprise in the described sleeve that the plane power transmission pulls wall 1 and subtract stress circle arc column face 2, in the cross section of described sleeve, the width that wall 1 is pulled in all plane power transmissions equates that every adjacent two plane power transmissions are pulled between the wall 1 and connected with the described stress circle arc column face 2 that subtracts.
2, a kind of sleeve that is used to install and remove hex bolts as claimed in claim 1, it is characterized in that: include 6 described plane power transmissions in the described sleeve and pull wall 1 and 6 described stress circle arc column faces 2 that subtract, pull the distance between the wall 1 if S is relative two described plane power transmissions, the described radius that subtracts stress circle arc column face 2 at 0.1S between the 0.12S.
