Abstract

The invention discloses a spark plug gap adjusting device. The device comprises a box body, a damping cavity is formed in the box body; a spark plug can be placed in the damping cavity; a fifth sliding groove with a forward opening is formed in the front end wall of the damping cavity. A threaded block in threaded connection with the fifth sliding groove is arranged in the fifth sliding groove. Afourth damping block located on the rear side of the threaded block and slidably connected with the fifth sliding groove is arranged in the fifth sliding groove. The front end wall of the fourth damping block is connected with the rear end wall of the threaded block through a fourth damping spring; a fourth sponge block is fixedly arranged on the rear end wall of the fourth damping block; a damping mechanism is arranged in the damping cavity; a bevel gear cavity located on the rear side of the damping cavity is formed in the box body. The top end of the first gear shaft is fixedly connected with the second gear, a knocking mechanism located on the rear side of the damping cavity is arranged in the box body, rack mechanisms located on the two sides of the second gear are arranged in the boxbody in a bilateral symmetry mode, the spark plug ceramic body can be better protected in the adjusting process, and the tiny gap distance can be better adjusted under slight knocking.

Description

technical field [0001] The invention relates to the technical field of spark plugs, in particular to a spark plug gap adjusting device. Background technique [0002] The spark plug is an important component of the ignition system of a gasoline engine. It can introduce high-voltage electricity into the combustion chamber and make it jump across the electrode gap to generate sparks, thereby igniting the combustible mixture in the cylinder. It is mainly composed of a wire nut, an insulator, a wire screw, a central electrode, a side electrode and a shell, and the side electrode is welded on the shell. [0003] At this stage, the gap of the spark plug often needs to be adjusted according to the different requirements. The existing device often causes damage to the ceramic body of the spark plug during the adjustment process. The adjustment process is often performed manually, and the gap distance cannot be finely adjusted. And The motor may be damaged by excessive force. Conte...
