Abstract
The utility model discloses a parallel flange is organized frock fast, including mounting flange, group to flange and integral key shaft, the one end vertical fixation of integral key shaft is in mounting flange's central authorities the cover is equipped with on the other end of integral key shaft the group is to the flange, and the two forms the key -type connection, the group to the flange with mounting flange's positioning connecting hole centering. The utility model discloses a through the integral key shaft connect, the mounting flange of the accurate centering of positioning connecting hole and group confirm the position of the parallel flange in pipeline nipple joint both ends to the flange, easy operation assembles fastly to can improve the equipment precision of parallel flange pipeline nipple joint. And simultaneously, the utility model discloses think about ingenious, simple structure, with low costs, application scope is extensive, has wide application promotion prospect.
Description
Technical field
The utility model relates to a kind of frock for parallel flange pipeline short section welding, and particularly quick group of a kind of parallel flange is to frock.
Background technology
There is a large amount of parallel flange pipeline short section in the pipeline of petrochemical production device, flange model is more, and parallel flange pipeline short section requires pipeline short section two ends parallel flange, the flange hole centering of two end flanges.Current, usual employing parallel rule and visual method install parallel flange pipeline short section two end flanges, and the advantage of the method is: the flange of any model can be installed, and shortcoming is: installation rate is slower, and precision is not high, and flange hole centering installs difficulty.Therefore, exploitation one can improve assembling speed, can ensure that again quick group of the parallel flange of assembly precision just seems particularly important to frock.
Summary of the invention
The utility model provides quick group of a kind of parallel flange to frock for solving in known technology the technical problem that exists, and this frock can improve the assembling speed of parallel flange pipeline short section, can ensure again the assembly precision of parallel flange pipeline short section.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is: quick group of a kind of parallel flange is to frock, comprise mounting flange, group to flange and splined shaft, one end of described splined shaft is vertically fixed on the central authorities of described mounting flange, the other end of described splined shaft is set with described group to flange, the two forms key and connects, the described group of hole centering that is located by connecting to flange and described mounting flange.
At described group to flange and described mounting flange being equipped with the hole that to be located by connecting described in many groups, the hole that is often located by connecting described in group comprises and is arranged on the hole that to be located by connecting described in same diametrically two.
Described splined shaft is octadentate splined shaft.
The advantage that the utility model has with good effect is: adopt be connected by splined shaft, the mounting flange of the hole precise alignment that is located by connecting and group determine the parallel flange in pipeline short section two ends position to flange, simple to operate, assembling speed is fast, and can improve the assembly precision of parallel flange pipeline short section.Meanwhile, the utility model is skillfully constructed, and structure is simple, and cost is low, applied widely, has wide application prospect.

In figure: 1, mounting flange; 2-1, left side flange; 2-2, right flange; 3, splined shaft; 4, take over; 5, group is to flange; 6, be located by connecting hole.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 ~ Fig. 4, a kind of quick group of parallel flange is to frock, comprise mounting flange 1, group to flange 5 and splined shaft 3, one end of described splined shaft 3 is vertically fixed on the central authorities of described mounting flange 1, the other end of described splined shaft 3 is set with described group to flange 5, the two forms key and connects, and described group to be located by connecting hole 6 centering of flange 5 with described mounting flange 1.
In the present embodiment, in order to the assembling enabling a set of frock be suitable for the parallel flange pipeline short section of the multiple different pressures grade of flange nominal diameter of the same race, be equipped with the many groups of holes that are located by connecting at described group on flange 5 and described mounting flange 1, often the group hole that is located by connecting comprises and is arranged on same two holes that are located by connecting diametrically.Described splined shaft 3 is octadentate splined shaft.
Using method of the present utility model:
Refer to Fig. 1, when assembling parallel flange pipeline short section, first completing the welding of left side flange 2-1 and adapter 4, and ensureing that adapter 4 is vertical with left side flange 2-1; Then the splined shaft 3 one end being welded with mounting flange 1 inserts in left side flange 2-1 and adapter 4, and fixes with two bolts according to the flange hole of flange rating by mounting flange 1 is located by connecting accordingly hole and left side flange 2-1; Subsequently, by right flange 2-2 group to the right side in adapter 4, subsequently, by group to flange 5 according to the right-hand member of hole centering mark installment at splined shaft 3 that be located by connecting; Rotate right flange 2-2, make flange hole on it and group to the flange hole centering of uniform pressure grade on flange 5, and be connected and fixed with two bolts.After completing the fixing of right flange 2-2 and adapter 3, can bolt be unclamped, group is unloaded frock.
Although be described preferred embodiment of the present utility model by reference to the accompanying drawings above; but the utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing under the ambit that the utility model aim and claim protect, can also make a lot of form, these all belong within protection domain of the present utility model.
