Abstract
The invention discloses a quick adjustment device for a core rod of a trolley, comprising a core rod and a tailstock welded vertically upward on the bed of a horizontal trolley, wherein a U-shaped groove with a notch facing upward is provided at the top of the tailstock along the length direction of the bed, and an inclined groove with the same width as the notch of the U-shaped groove and inclined upward is provided below the U-shaped groove along the length direction of the bed; a hollow external threaded tube with the same outer diameter as the notch width and the external threaded tube is clamped in the notch of the U-shaped groove and the inclined groove, and the external threaded tube is located on the left and right sides of the notch and is respectively threadedly connected with a left large nut and a right large nut; the tail end of the core rod passes through the center hole of the external threaded tube and is threadedly connected with a nut for preventing the core rod from being pulled out of the external threaded tube. The invention can not only realize the simultaneous fixing of multiple core rods, thereby improving the efficiency of drawing aluminum alloy tubes, but also conveniently realize the rapid adjustment of the front and rear positions of the core head and the rapid replacement of core rods of different specifications, further improving the efficiency of drawing aluminum alloy tubes.
