Abstract
The invention discloses a well casing quick assembling welding equipment and a welding method of the well casing quick assembling welding equipment. The well casing quick assembling welding is characterized in that a pair of positioning flanges is fixedly arranged on a lathe chuck and a lathe tailstock, respectively; the planes of flange plates of the pair of positioning flanges are vertical to the central axis of the lathe chuck and the lathe tailstock; well casing flanges are fixedly arranged on the opposite faces of the pair of positioning flanges through flange holes by using bolts respectively; and a straight pipe section of the well casing is fixedly blocked between the a pair of well casing flanges. According to the invention, the work efficiency on the assembling and welding of the well casing can be obviously improved through the lathe chuck and the lathe tailstock which are arranged on the same central axis and by arranging the positioning flanges; and the process is simple; and the welding quality is high.
Description
Technical field
The present invention relates to a kind of equipment and welding method that is used for well casing is assembled welding.
Background technology
Well casing is to be welded with the well casing flange at the two ends of a straight length; Welding assembly for well casing is to rely on manual work to carry out contraposition at present, accomplishes welding again, still; This form is difficult to guarantee the axis of straight length and the perpendicularity between the Flange Plane; Need in welding process, constantly proofread and correct, process is quite time-consuming, difficult quality guarantee.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, provide a kind of well casing to assemble welding jig and welding method fast so that quick for the assembling welding process of well casing, quality is high.
The present invention adopts following technical scheme for the technical solution problem:
The design feature that well casing of the present invention is assembled welding jig fast is: a pair of locating flange is fixedly installed on respectively on lathe chuck and the tail stock, and the ring flange plane of said a pair of locating flange is vertical with the central axis of tailstock seat with lathe chuck; On the relative one side of said a pair of locating flange, respectively through flange hole and utilize bolt that the well casing flange is set, the well casing straight length fixes between a pair of well casing flange.
The characteristics that well casing of the present invention is assembled the welding manner of welding jig fast are to carry out as follows:
A, a pair of locating flange is is fixedly installed on relatively respectively on lathe chuck and the tail stock; Utilization is in the relative position state that lathe chuck and tail stock on the same central axis guarantee a pair of locating flange;
B, with a pair of well casing flange through flange hole and utilize and to be bolted on the said locating flange, obtain the centralized positioning of a pair of well casing flange;
C, the well casing straight length is fixed between a pair of well casing flange, and straightening;
D, between well casing straight length and a pair of well casing flange, carry out spot welding, make well casing straight length and well casing flange be able to fix;
E, the well casing straight length that will fix and well casing flange take off from lathe and accomplish the complete cycle welding.
The characteristics that well casing of the present invention is assembled the welding manner of welding jig fast also are: welding with the complete cycle of well casing flange for the well casing straight length among the said step e is that well casing straight length and the well casing flange that spot welding is fixedly connected is set to erectility, and said erectility is meant that said well casing straight length is vertical state.
Compared with present technology, utilization of the present invention is in lathe chuck and the tailstock seat on the same central axis, and through locating flange is set, can significantly improve the operating efficiency of well casing assembling welding, and process is simple, and welding quality is high.

Fig. 4 accomplishes the well casing sketch map of welding for the present invention;
Label among the figure: 1 locating flange; 2 lathe chucks; 3 tail stocks; 4 well casing flanges; 5 well casing straight lengths; 6 lathes.
The specific embodiment
Referring to Fig. 3; The structure that well casing is assembled welding jig fast in the present embodiment is set to: a pair of locating flange 1 is fixedly installed on respectively on lathe chuck 2 and the tail stock 3, and the ring flange plane of a pair of locating flange 1 is vertical with the central axis of tailstock seat 3 with lathe chuck 2; On the relative one side of said a pair of locating flange 1, respectively through flange hole and utilize bolt that well casing flange 4 is set, well casing straight length 5 fixes between a pair of well casing flange 4.
In the practical implementation, the welding manner that well casing is assembled welding jig fast carries out as follows:
1, a pair of locating flange 1 is is fixedly installed on relatively respectively on lathe chuck 2 and the tail stock 3; Utilization is in the relative position state (as shown in Figure 1) that lathe chuck 2 and tail stock 3 on the same central axis guarantees a pair of locating flange 1;
2, a pair of well casing flange 4 is bolted on the said locating flange 1 through flange hole and utilization, obtains the centralized positioning (as shown in Figure 2) of a pair of well casing flange 4;
3, well casing straight length 5 is fixed between a pair of well casing flange 4, and straightening (as shown in Figure 3);
4, between well casing straight length 5 and a pair of well casing flange 4, carry out spot welding, make well casing straight length 5 and well casing flange 4 be able to fix (as shown in Figure 3);
5, the well casing straight length that will fix 5 and well casing flange 4 from lathe 6 take off accomplish the complete cycle welding (as shown in Figure 4); In the practical implementation; Is that the well casing straight length 5 that spot welding is fixedly connected is set to erectility with well casing flange 4 for well casing straight length 5 with the complete cycle welding of well casing flange 4; Erectility is meant that well casing straight length 5 is vertical state, and this state helps complete cycle welding rapidly and efficiently more.
