Abstract
The utility model relates to a mechanical processing equipment of pipes, in particular to an aligning inner support structure. The aligning inner support structure mainly solves the problems existed in the prior art and provides a multilevel adjustment inner support structure. The adopted technical proposal for solving the technical problems is as follows: a multilevel adjustment inner support structure is characterized by comprising a taper sleeve; a shell of the taper sleeve is provided with four multilevel adjusting devices symmetrically. The multilevel adjustment is formed by the sleeving of adjusting bolts which are hollow; and adjusting nuts which are matched with the previous adjusting bolts are arranged in the adjusting bolts. The multilevel adjustment inner support structure has the advantages of simple and reasonable structure and convenient use, can realize multilevel adjustment in large range by the multilevel adjusting devices, can automatically align and realize the connection of different tolerance shafts.
Description
Technical field:
The utility model relates to a kind of tubing machining equipment, relates in particular to a kind of self-aligning inner supporting structure.
Background technology:
China's utility model patent 0154870.7 discloses a kind of steel pipe inner supporting device, and it comprises inner supporting body, pull bar, lining, adjustment ring, elastomer, centrum ring, guiding top, pressure ring; The pull bar activity is installed in the inner supporting body, and it is spacing fixing by pressure ring, the pull bar top is fixed in described guiding top, centrum ring, lining are sheathed on the pull bar successively, between guiding top and interior support, elastomer sheathed with lining on, this adjustment ring set is located on the pull bar, between lining and inner supporting body.Pulling pull bar motion is moved after making the centrum hoop, forces the flexible body compression outwards to be expanded, and makes the flexible body outer ring support to tube wall.But this apparatus structure more complicated make difficulty, and the support force of flexible body is not enough.
Summary of the invention:
The utility model has mainly solved the problem that above-mentioned prior art exists, and a kind of multistage adjustment inner supporting structure is provided
The technical scheme that its technical problem that solves the utility model adopts is: a kind of multistage adjustment inner supporting structure, it is characterized in that: comprise tapered sleeve, on the housing of tapered sleeve, be symmetrically arranged with four multistage adjusting devices, this multistage adjusting device is socketed to form by some adjustment bolts that are hollow shape, is provided with upper level between the adjustment bolt and adjusts the adjustment nut that bolt is complementary.
As a kind of preferred version of such scheme, the intermediate throughholes inwall of described adjustment bolt is provided with screw thread, and the next stage bolt is connected by screw thread with this through hole.Described adjustment bolt is an one-level cover one-level, also is provided with between the bolt with upper level and adjusts the adjustment nut that bolt is complementary, and screws the adjustment nut, can by multistage bolt is set, can adjust the scope of support so that two-stage is adjusted bolt to closely cooperate.
As a kind of preferred version of such scheme, final stage bolt is provided with lid.Lid is contacted with inboard wall of tube body.
As a kind of preferred version of such scheme, self-aligning bearing is installed in the middle of the described tapered sleeve.Can realize connection to different tolerance axles.
As a kind of preferred version of such scheme, be provided with taper hole in the middle of the described self-aligning bearing, this self-aligning bearing is installed on the diminished shaft.
The utility model has the advantages that simple and reasonablely, easy to use, can realize multistage large-scale adjustment by multistage adjusting device, and can automatic aligning, realize connection to different tolerance axles.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of blast structural representation of the multistage adjusting device of the utility model.
The specific embodiment:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described.
Embodiment:
According to shown in Figure 1, the utility model mainly comprises tapered sleeve 1, described tapered sleeve is the toroidal of middle band through hole, the tapered sleeve through hole is provided with intermediate sleeve, self-aligning bearing 2 is installed in the intermediate sleeve, this self-aligning bearing is arranged on the diminished shaft, on the tapered sleeve shell, be symmetrically arranged with four multistage adjusting devices 4, as shown in Figure 2, provided a kind of by three grades of schematic diagrames of adjusting bolt sleeve, described suit bolt is the hollow shape bolt, and through-hole wall is provided with internal thread, and adjusting bolt is that one-level cover one-level is socketed to form, one-level is adjusted bolt 41 and is linked to each other with tapered sleeve, between one-level adjustment bolt 41 and tapered sleeve, be provided with one-level and adjust nut 51, screw one-level and adjust nuts and bolt, adjust connection secondary adjustment bolt 42 on the bolt in one-level then, secondary is adjusted bolt and is provided with secondary adjustment nut 52, screw secondary then and adjust nuts and bolt, adjust at secondary according to said method again three grades of adjustment bolts 43 and three grades of adjustment nuts 53 are set on the bolt 42 again, described three grades of adjustment bolts are provided with lid.
Specific embodiment described herein only is that the present invention's spirit is illustrated.The technical staff of the technical field of the invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has used tapered sleeve morely, self-aligning bearing, one-level are adjusted bolt, one-level is adjusted terms such as nut, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present invention more easily; They are construed to any additional restriction all is contrary with spirit of the present invention.
