Abstract

A porous clamp device capable of automatically centering and drilling long-thin steel-sheet type parts relates to a porous centering and drilling clamp device for long-thin steel sheets, and solves the problem that a porous processing mold for the long-thin steel sheets is complex in structure, long in processing period, high in cost, low in punching accuracy and the like. A claw and a sliding top block are slidingly matched with two first sliding chutes on a base, two nuts are arranged in two second sliding chutes on the base and slidingly matched with the second sliding chutes and fixed with the claw and the sliding top block, a stop plate is arranged on the claw which is detachably connected with a slide plate, an inverted isosceles trapezoid groove and a long groove for storing drilling parts are formed between the claw and the sliding top block, a mold is inverted in the isosceles trapezoid groove, a fastening screw leans on the mold, a drill bushing is inlaid in a drilling bushing hole of the mold, a positioning block of a screw rod is arranged in a screw rod support seat on the base, and two ends of the screw rod are connected with the two nuts in a threaded manner. The porous clamp device is used for clamping and fixing in drilling of the long-thin steel-sheet type parts.

Description

technical field [0001] The invention relates to a multi-hole clamping device for centering drilling of long and thin steel plate parts. Background technique [0002] When drilling long and thin steel parts, conventional stamping and punching processing methods are often used. The punching process of long and thin steel parts requires the design of a special die, which has complex structure, long processing cycle and high cost, and the center line of the punched hole is prone to deflection, and the punching accuracy is low, so it is difficult to ensure the porousness of long and thin steel parts. Processing quality. Contents of the invention [0003] The purpose of the present invention is to solve the problem of the complex structure of the porous machining mold for long and thin steel parts, long processing cycle and high cost, and the center line of the punching hole is prone to deflection, the punching precision is low, and it is difficult to ensure the long and thin s...
