Abstract
The utility model provides a kind of novel steel tube weld jig, comprise the steel pipe support and two steel pipe folders of placing steel pipe to be welded, two steel pipe folder cross sections are C shape, the form fit of C shape bottom shape and steel pipe support, two steel pipe folders are arranged at steel pipe support two ends respectively, two steel pipe folders are equipped with bolt hole, and be equipped with fastening bolt in bolt hole, the screw rod bottom of fastening bolt is provided with canvas.When the utility model can be avoided welding, the screw rod bottom of fastening bolt produces steel tube surface and scratches, and can firmly fix steel pipe to be welded, can improve the welding quality of steel pipe nozzle.
Description
Technical field
The utility model belongs to steel-pipe welding apparatus field, especially relates to a kind of novel steel tube weld jig.
Background technology
Often need to weld steel pipe in steel pipe uses, in order to steel pipe nozzle can concordant, steel pipe center line can be alignd, those skilled in the art designs multiple steel-pipe welding equipment.A kind of steel-pipe welding fixture is just provided in the Chinese patent that publication number is CN202607176U, but this steel-pipe welding fixture uses fastening bolt to fix steel pipe, although can ensure that steel pipe nozzle is concordant, but easily steel tube surface is scratched, affect the quality of steel pipe, and then affect the service life of steel pipe; Moreover fastening bolt easily slides when welded still pipe, thus affects welding quality.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of novel steel tube weld jig that tube quality also can improve steel pipe nozzle welding quality that can ensure.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of novel steel tube weld jig, comprise the steel pipe support (1) and two steel pipes folder (2) of placing steel pipe to be welded, two described steel pipe folder (2) cross sections are C shape, the form fit of C shape bottom shape and described steel pipe support (1), two described steel pipes folder (2) are arranged at steel pipe support (1) two ends respectively, two described steel pipes folder (2) are equipped with bolt hole, fastening bolt (21) is equipped with in described bolt hole, the screw rod bottom of described fastening bolt (21) is provided with canvas (3).
Preferably, described canvas (3) is wrapped in whole described fastening bolt (21) outside.
Preferably, described canvas (3) is fixed on the screw rod bottom of described fastening bolt (21) by nut (5).
Further, cushion (6) is also provided with between the screw rod bottom of described canvas (3) and described fastening bolt (21).
Further, described cushion (6) is rubber layer.
The advantage that the utility model has and good effect are: owing to adopting technique scheme, and when can avoid welding, the screw rod bottom of fastening bolt produces steel tube surface and scratches, and can firmly fix steel pipe to be welded, can improve the welding quality of steel pipe nozzle.

Detailed description of the invention
In order to better understand the utility model, below in conjunction with specific embodiments and the drawings, the utility model is conducted further description.
Embodiment 1
The utility model embodiment 1 provides a kind of novel steel tube weld jig, as shown in Figure 1, Figure 2 and Figure 3, comprise the steel pipe support 1 and two steel pipe folders 2 of placing steel pipe to be welded, it is C shape that two steel pipes press from both sides 2 cross sections, the form fit of C shape bottom shape and steel pipe support 1, two steel pipe folders 2 are arranged at steel pipe support 1 two ends respectively, two steel pipe folders 2 are equipped with bolt hole, fastening bolt 21 is equipped with in bolt hole, the screw rod bottom of fastening bolt 21 is provided with canvas 3, and canvas 3 is wrapped in outside whole fastening bolt 21.
The course of work of this example: before fastening bolt 21 through bolt hole, by fastening bolt 21 outer wrap one deck canvas 3, then puts into bolt hole by fastening bolt 21.Steel pipe 4 is put on steel pipe support 1, fix steel pipe 4 with fastening bolt 21; An other steel pipe to be welded is put on steel pipe support 1, by two steel pipe nozzle alignment, screws another one fastening bolt 21, this steel pipe is fixed, carry out spot welding at weld bond place 41, after spot welding completes, remove fixture again, continued whole welding.
Embodiment 2
The utility model embodiment 2 provides a kind of novel steel tube weld jig, and as shown in Fig. 4, Fig. 5 and Fig. 6, in the present embodiment 2, canvas 3 is fixed on the screw rod of fastening bolt 21 by nut 5 as different from Example 1.
The course of work of this example: as different from Example 1, first by fastening bolt 21 through bolt hole, then wrap up one deck canvas 3 with nut 5 in the screw rod bottom of fastening bolt 21, all the other fixing steel pipe steps are identical with embodiment 1.Compared with embodiment 1, embodiment 2 more easily changes canvas 3, when after use a period of time, nut 5 can be backed out, and changes canvas.
Embodiment 3
The utility model embodiment 3 provides a kind of novel steel tube weld jig, and as shown in Figure 7, on the basis of embodiment 2, be also provided with cushion 6 between the screw rod bottom of canvas 3 and fastening bolt 21, in the present embodiment, cushion 6 is rubber layer.The setting of cushion 6 is more conducive to protecting steel pipe 4 surface to be welded not to be scratched.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
