Quick self-locking jaw structure

Technical Field

The utility model relates to a from locking-type structure of keeping silent fast belongs to anchor clamps technical field.

Background

The jig is a device for fixing a processing object to occupy a correct position for receiving construction or inspection in a machine manufacturing process, and is also called a jig. In a broad sense, any device used to quickly, conveniently and safely mount a workpiece at any stage in a process may be referred to as a jig. One of the most common types of clamps is flat nose pliers. The flat tongs are machine vices, which mainly fix the small workpiece on the working platform, i.e. the small workpiece is clamped by the clamping pieces at the two ends so as to carry out cutting processing. Currently, the main fittings of flat-nose pliers include: base, holder, fixing base, screw rod, the fixing base cup joints on the screw rod to remove about rotating along with the screw rod, on the holder was fixed in the fixing base, the top of base was arranged in to the fixing base, and the base provides supporting platform for the fixing base. The clamping piece is fixed by utilizing a groove on the fixing seat in the assembling process of the clamping piece, namely sliding the clamping piece into the groove of the fixing seat and then embedding a pin, a bolt key or a screw between the groove and the clamping piece, and tools such as a screwdriver and the like need to be matched and used in the assembling/disassembling process.

Because in the above-mentioned structure, utilized pin, bolt key or screw for the holder is more difficult from the fixing base dismantlement, and it is big to keep silent the repacking degree of difficulty, and is long-time, can't fix a position reuse fast accurately. Therefore, the quick self-locking jaw structure is designed, the clamping piece can be quickly installed and disassembled by the aid of the self-locking structure, the installing and disassembling difficulty is reduced, the installing time is shortened, and the whole body is stable and firm after the clamping piece is assembled.
