Abstract
The utility model discloses a thin-wall pipe fitting straightening device which comprises a sleeve cylinder. The top of the sleeve cylinder is connected with an upper flange. The bottom of the sleeve is connected with a lower flange. A raised circular loop is formed in the upper portion of the lower flange. A raised quadrate pillar is formed in the middle of the lower portion of the lower flange. A hole is formed in the center of the quadrate pillar. Three straightening roller which are arranged triangularly are arranged in the interior of the sleeve cylinder and between the upper flange and the lower flange. One end of each straightening roller is sleeved in the circular loop through a bearing. The other end of each straightening roller is installed in the upper flange through a bearing. A thin-wall pipe fitting to be straightened is arranged in the middle of the three straightening rollers. The thin-wall pipe fitting straightening device is simple in structure, convenient to manipulate, low in cost and good in straightening quality.
Description
Technical field
The utility model belongs to a kind of straightener, is specifically related to a kind of straightener that is applicable to thin-wall pipe.
Technical background
In industrial production, need the metal thin-wall pipe fitting that machines because its external diameter is smaller, wall ratio is thinner, and pipe fitting the axiality precision prescribed with endoporus is high to foreign round need to have higher linearity and Vehicle Processing before processing after.The straightener of prior art mostly is long material heavy wall aligning, and very easily crooked behind aligning to long thin-wall pipe.
Summary of the invention
The utility model is the shortcoming that exists in order to overcome prior art, and its objective is provides a kind of thin-wall pipe straightener that length is shorter, external diameter is less that is applicable to.
The technical solution of the utility model is: a kind of straightener of thin-wall pipe, comprise sleeve, top at sleeve is connected with upper flange, bottom at sleeve is connected with lower flange, be formed with the annulus of a projection on the top of lower flange, in the middle of the bottom of lower flange, be formed with the square column of a projection, form porose at the center of square column.Sleeve inner, on be provided with three smoothing rolls that are triangle arrangement between the lower flange, an end of smoothing roll is installed in the annulus by bearing, the other end of smoothing roll is installed in the upper flange by bearing.
Described upper flange is connected the top by screw and is connected with sleeve, lower flange is connected the bottom by screw and is connected with sleeve.
Place thin-wall pipe to be aligned in the centre of described three smoothing rolls.
The utility model is simple in structure, easy to operate, cost is low, and straightening quality is good.
Description of drawings
Fig. 1 is the cutaway view (along the A-A line section among Fig. 2) of the straightener of the utility model thin-wall pipe;
Fig. 2 is the top view of the straightener of the utility model thin-wall pipe;
Scheme of installation when Fig. 3 is the utility model work.
Wherein:
1 sleeve, 2 upper flanges
3 lower flanges, 4 smoothing rolls
5 bearings, 6 screws
7 annulus, 8 square column
9 holes, 10 thin-wall pipes
11 machine tool three-jaw chucks, 12 push rods
13 lathe cutter saddles.
The specific embodiment
Below, be elaborated with reference to the straightener of drawings and Examples to the utility model thin-wall pipe:
As shown in Figure 1, 2: a kind of straightener of thin-wall pipe, comprise sleeve 1, be connected with upper flange 2 at the top of sleeve 1, be connected with lower flange 3 in the bottom of sleeve 1.Wherein, be formed with the annulus 7 of a projection on the top of lower flange 3, in the middle of the bottom of lower flange 3, be formed with the square column 8 of a projection, form porose 9 at the center of square column 8.
Sleeve 1 inside, on be provided with three smoothing rolls 4 that are triangle arrangement between the lower flange 2,3, an end of smoothing roll 4 is installed in the annulus 8 by bearing 5, the other end of smoothing roll 4 is installed in the upper flange 2 by bearing 5.
The top that upper flange 2 is connected with sleeve by screw 6 connects, and the bottom that lower flange 3 is connected with sleeve by screw 6 connects.
Place thin-wall pipe to be aligned 10 in the centre of three smoothing rolls 4.
The course of work of the present utility model is:
As shown in Figure 3: at first, the push rod 12 that is installed in machine tool three-jaw chuck 11 guarantees that push rod 12 is concentric with machine tool chief axis.Then, the straightener of the utility model thin-wall pipe is fixed on the lathe cutter saddle 13, take the machine tool chief axis center as benchmark, utilizes lever indicator centering straightener, do not move radially the lathe supporting plate behind the centering.Again, with an end of thin-wall pipe push rod 12 1 ends of packing into, mobile lathe slide carriage makes the other end of thin-wall pipe 10 enter the centre of three smoothing rolls 4 of straightener.Again, open the machine tool chief axis rotation, push rod 12 drives thin-wall pipe and rotates, and mobile lathe slide carriage moves to major axes orientation simultaneously, utilizes three smoothing roll revolving-rolling aligning thin-wall pipes.
The utility model is simple in structure, easy to operate, cost is low, and straightening quality is good.
