Adjustable clamp used for marine deck welding test

Abstract

An adjustable clamp used for a marine deck welding test includes a supporting device, a guiding and positioning device and a clamping device; the guiding and positioning device comprises a plurality of guiding shafts, a plurality of guiding plates and a plurality of positioning rods, the guiding shafts located at the two sides of a working platform are detachably connected with supporting blocks, the guiding shafts penetrate through the guiding plates, the guiding plates can slide horizontally along the guiding shafts, at least one column of through-holes are formed in each guiding plate in the direction perpendicular to the sliding direction, the through-holes located at the central part are guiding plate bolt holes, the through-holes located at the two sides are guiding plate positioning holes, the positioning rods are placed in the guiding plate positioning holes, and the upper ends of the positioning rods are higher than the guiding plates; the clamping device comprises a plurality of pressing plates located on the upper parts of the guiding plates and provided with pressing plate bolt holes corresponding to the guiding plate bolt holes, and the pressing plates are connected with the guiding plates via bolts. The clamp provided in the present invention has advantages including simple structure, easy operation, low cost, accurate positioning, and the positioning points and the clamping force can be adjusted at will.
