Background technology
In welding process, in order to ensure to weld with workpiece to be welded main body to be welded shown in Fig. 1 and Fig. 2 according to set position, and both do not misplace in welding process, with regard to highly desirable a kind of position welding jig, to realize reliable location.Existing position welding jig often structure is complicated, operation inconvenience, there is presently no a kind of simple in construction, positions quick position welding jig.
Summary of the invention
For solving the deficiencies in the prior art, it is an object of the invention to provide a kind of position welding jig, simple in construction, it is possible to position easily and fast and reliably in welding process.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that:
Position welding jig, it is characterised in that include the tool main body that bottom surface is plane, the end face of above-mentioned tool main body caves inward formation concave face, above-mentioned concave face be provided with for main body to be welded and the location structure of work pieces mate to be welded;After main body to be welded and workpiece to be welded are positioned by above-mentioned position welding jig, welding space is left in side.
Aforesaid position welding jig, it is characterised in that the bottom shape of above-mentioned tool main body is rectangle.
Aforesaid position welding jig, it is characterised in that above-mentioned concave face is parallel to above-mentioned bottom surface and the rectangle less than above-mentioned bottom surface.
Aforesaid position welding jig, it is characterised in that above-mentioned location structure is the positioning convex of the end face exceeding above-mentioned tool main body.
Aforesaid position welding jig, it is characterised in that above-mentioned positioning convex includes: for the first positioning convex coordinated with main body to be welded, for multiple second positioning convex with work pieces mate to be welded.
Aforesaid position welding jig, it is characterised in that above-mentioned positioning convex is rotary structure.
Aforesaid position welding jig, it is characterised in that above-mentioned first positioning convex is arranged on the center of above-mentioned concave face.
Aforesaid position welding jig, it is characterised in that the quantity of above-mentioned second positioning convex is 4, is arranged on four edges of concave face.
The invention have benefit that: the position welding jig simple in construction of the present invention, it is provided with integrally formed with tool main body, for the location structure that main body to be welded and workpiece to be welded are positioned, it is possible to realize positioning easily and fast and reliably.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention made concrete introduction.
Main body to be welded 1 shown in Fig. 1 and Fig. 2 and workpiece to be welded 2 can be positioned by the position welding jig of the present invention quickly and easily so that both will not misplace in welding process, improve the precision of welding.It will be seen that main body to be welded 1 and workpiece to be welded 2 have been respectively formed retaining structure 3 from Fig. 1 and Fig. 2, i.e. it is used to the structure of location, mostly typically is through hole.
Seeing Fig. 3 to Fig. 5, the position welding jig of the present invention includes: bottom surface 4 is that plane, end face 5 cave inward and be formed with the tool main body of concave face 6, is just arranged on concave face 6 for the location structure coordinated with main body 1 to be welded and workpiece to be welded 2.
In order to not affect the carrying out of welding operation, position welding jig is after positioning main body 1 to be welded and workpiece to be welded 2, and welding space 7 should be left in its side.It is to say, the upper surface of tool main body should not contact with the surface of main body 1 to be welded, the working place that may be used for welding should be left between the two.
As a kind of preferred implementation, the bottom surface 4 of tool main body is shaped as rectangle, with main body 1 to be welded be shape.Concave face 6 is parallel to above-mentioned bottom surface 4 and the rectangle less than above-mentioned bottom surface 4.
As shown in Figure 4 and Figure 5, position welding jig is in use, its location structure matches with the retaining structure 3 of main body 1 to be welded and workpiece to be welded 2, so, location structure preferably exceeds the positioning convex of the end face 5 of tool main body, preferred as one, positioning convex and tool main body are integrally formed.
Further, positioning convex includes: the first positioning convex 8 coordinated with main body 1 to be welded, and multiple second positioning convex 9 coordinated with workpiece 2 to be welded, the first positioning convex 8 is corresponding with the shape of retaining structure 3 with the shape of the second positioning convex 9.In view of the retaining structure 3 of main body 1 to be welded in the present embodiment and workpiece to be welded 2 is all circular through hole, the first positioning convex 8 and the second positioning convex 9 are disposed as rotary structure, and this structure not only positions reliably but also the most convenient.
Corresponding to actual demand, the first positioning convex 8 arranges the center stating concave face 6.The quantity of the second positioning convex 9 is 4, is arranged on four edges of concave face 6.
The ultimate principle of the present invention, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry, above-described embodiment limits the present invention, the technical scheme that the mode of all employing equivalents or equivalent transformation is obtained the most in any form, all falls within protection scope of the present invention.
