In the figure: the clamp comprises a bench clamp 1, a clamp 2, an arc-shaped block 3, an outer arc part 31, a central arc part 32, an inner arc part 33, a limiting bead 4, a limiting hole 5 and a spring 6.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in fig. 1-3, spot welding positioning device includes vise 1 and

clamp

2, and 2 one end cards of clamp are in 1 clamping part of vise, and fixedly connected with arc piece 3 respectively on two inside lateral walls of 2 clamping part of clamp, and two arc pieces 3 are the mirror image setting in 2 inside of clamp, and the one end of every arc piece 3 all is located the outside of 2 clamping part of clamp.

Each arc-shaped block 3 is respectively welded with the inner side wall of the clamping part of the clamp 2.

Each arc block 3 is a telescopic arc block.

Retractable arc piece includes first arc portion 31, second arc portion 32, third arc portion 33 … … nth arc portion, n is more than or equal to 2's positive integer, and first arc portion 31, second arc portion 32, the internal diameter of third arc portion 33 … … nth arc portion reduces in proper order, the lateral wall of first arc portion 31 is fixed with the clamping portion of clamp 2, and first arc portion 31, second arc portion 32, detachable sliding connection between two liang of third arc portion 33 … … nth arc portion.

First arc portion 31 inside wall one end, the one end of second arc portion 32 inside wall, spacing hole 5 has all been seted up to the one end … … n-1 of the one end … … of third arc portion 33 inside wall one end, the both sides of second arc portion 32 lateral wall tip, the equal fixedly connected with spring 6 in both sides of the both sides … … nth arc portion lateral wall tip of third arc portion 33 lateral wall tip, n is more than or equal to 2's positive integer, the equal fixedly connected with of the other end of every spring 6 and spacing pearl 4 of spacing hole 5 matched with.

The working principle is as follows: when the pipeline welding clamp is used, firstly, the clamp is fixed by using the bench clamp, a certain angle is formed between the clamping part of the clamp and the clamping part of the bench clamp, the angle can be adjusted according to the actual condition, the range is 0-180 degrees, then according to the actual size of a pipeline, the size of the arc-shaped block 3 of the pipeline is adjusted by sequentially adopting a detachable sliding mode for the first arc part 31, the second arc part 32, the third arc part 33 and the nth arc part … …, wherein n is a positive integer greater than or equal to 2, and then the pipeline is welded by using a welding gun;

the specification and size forming process of the arc-shaped block 3 is as follows:

i, after one end of the second arc part 32 extends into the first arc part 31, the second arc part 32 slides in the first arc part 31 until the limiting bead 4 on the outer side wall of the second arc part 32 is bounced into the limiting hole of the first arc part 31 under the action of the spring 6, so that the combination of the second arc part 32 and the first arc part 31 is realized,

II, the combination between the third arc part 33 and the second arc part 32, … …, the combination between the nth arc part and the (n-1) th arc part are carried out according to the mode I, and n is a positive integer more than or equal to 2;

III, realizing the specification change of the arc block 3 by adopting the modes I and II.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications fall within the scope of the claimed invention.
