Abstract

The invention relates to a metal chuck used for being matched with a bolt to achieve high-strength connection, the metal chuck comprises a first clamping piece, a second clamping piece, a connecting piece, a locking nut and an anti-disengaging spring bolt, and the first clamping piece and the second clamping piece are connected through the connecting piece; a clamping groove used for clamping a first to-be-connected plate and a second to-be-connected plate is formed between the first clamping piece and the second clamping piece, and the locking nut is connected to the upper portion of the first clamping piece and used for locking a bolt penetrating through the second clamping piece, the second to-be-connected plate, the first to-be-connected plate and the first clamping piece. The first clamping piece is connected with the second clamping piece to achieve fastening connection between the first to-be-connected plate with the through hole and the second to-be-connected plate with the through hole, and the anti-disengaging spring bolt is connected to the upper portion of the second clamping piece and used for being clamped into the through hole of the second to-be-connected plate to prevent the second to-be-connected plate from moving or disengaging. Compared with the prior art, two modes of clamping and bolt connection are adopted at the same time, and high-strength connection can be achieved.

Description

technical field [0001] The invention belongs to the technical field of connectors, and in particular relates to a metal chuck used to cooperate with bolts to realize high-strength connection. Background technique [0002] At present, most of the deep-drawing nuts suitable for the welding bolts of automobile bodies have a single-thread structure, and the body parts are locked and fixed by torque guns. In most cases, the structural nut is only suitable for fastening with low torque, and its strength is low. It is easy to loosen and fall off under long-term vibration of the vehicle body. Generally, the fastening strength is improved by increasing the torque, but this method is likely to cause the thread to slip and fail, and the nut cannot be withdrawn directly after the thread slips, which affects the loading rhythm. [0003] Chinese patent CN 203926310U discloses a fast mounting nut for connecting sheet metal parts, including an upper clamping piece, a lower clamping piece, ...
