Furthermore, the end fixing positioning piece and the end moving positioning piece are channel steel, and the notch of the end fixing positioning piece and the notch of the end moving positioning piece are arranged oppositely.

Compared with the prior art, the utility model discloses the beneficial effect who possesses is:

through the arrangement of the utility model, the crawling ladder to be welded can be placed on the base, the two ends of the two cubic columns of the crawling ladder are limited between the corresponding end part fixing positioning piece and the corresponding end part movable positioning piece, and then the cubic columns are pressed tightly through the pressing block, so that the two columns of the crawling ladder are effectively prevented from being dislocated during welding to influence the welding effect; meanwhile, the distance between the end part movable positioning piece and the end part fixed positioning piece can be adjusted adaptively according to the ladders with different lengths, and the application range is relatively wide.

Detailed Description

The invention will now be further elucidated with reference to the accompanying drawings. The following is only a preferred structure of the present invention, and is not intended to limit the scope of the present invention. Any equivalent or similar replacement without departing from the concept of the present invention shall fall within the protection scope of the present invention. And the terms of orientation such as "left", "right", "front", "back", etc. are defined with reference to fig. 1 and should not be construed as limiting the scope of the present application.

As shown in figures 1-3, the utility model relates to a novel clamp for welding suspension arm, which comprises a base 1, four corners at the bottom of the base 1 are fixed with four columns through bolts, the base stands on the ground through the four columns (not shown in the figures), two end fixing positioning pieces 2 are fixed at the top of the left end of the base 1 through bolts or welding, two end moving positioning pieces 3 are arranged at the top of the right end of the base 1, two sliding chutes 1.1 are arranged at the positions for installing the two end moving positioning pieces 3 on the base 1, the extending direction of each sliding chute 1.1 is designed based on approaching or separating from the end fixing positioning pieces 2, each sliding chute 1.1 runs through the top and the bottom of the base 1, a sliding rod is fixed at the bottom of each end moving positioning piece 3 through welding, the two sliding rods pass through the respective sliding chutes 1.1 and then are welded at the bottom with the same connecting block 4, the right center of the connecting block 4 is connected with one end of a rotating rod 5 through a bearing seat and a bearing, the periphery of the rotating rod 5 is provided with external threads, correspondingly, a threaded sleeve 6 with internal threads is welded and fixed at a corresponding position at the bottom of the base 1, the rotating rod 5 penetrates through the threaded sleeve 6 and is in threaded fit with the threaded sleeve 6, and the other end of the rotating rod 5 is welded with a rotating handle 7; two end fixing location spare 2 and two end activity setting spare 3 one-to-one are spacing in order to be used for carrying on the both ends of two cube posts of cat ladder, and one of them end fixing location spare 2 constitutes a set of tip locating component rather than corresponding one end activity setting spare 3, it is provided with a plurality of briquetting 8 to lie in between every group tip locating component on base 1, every briquetting 8 passes through the bolt fastening on base 1, set up the screw hole that runs through its top and bottom promptly on base 1's the suitable position, also need the trompil on the briquetting, the bolt from the hole of briquetting from top to bottom pass behind the briquetting and the screw hole screw-thread fit on the base.
