The invention discloses a phosphorizing device for coating a crank of an electric bicycle. The device comprises a bottom plate, wherein a phosphorizing pool and an airing pool are arranged on the bottom plate; a phosphorizing liquid tank is arranged on the bottom plate which is provided with a guide pipe, a lifting pipe is sleeved by the guide pipe, a lifting guide rail is arranged on the end part of the lifting pipe, grooves are formed on two side walls of the end part of the guide pipe, and rotary wheels which are in threaded connection with the lifting pipe are arranged in the grooves; the lifting guide rail is sleeved by a slide block which is provided with a pull rope, a storage frame is arranged in the phosphorizing pool, and the storage frame is connected with a pull rope. According to the device disclosed by the invention, the crank is phosphorized, so that the surface of the crank is plated by a phosphorizing film; the slide block slides along the lifting guide rail to control the storage frame to be immersed into the airing pool; the phosphorized crank is aired through a fan, a blowing duct and a blowing opening, so that the surface of the treated crank is smooth and the service life of the crank is long.
Description
technical field [0001] The invention relates to a coating and phosphating device, in particular to a coating and phosphating device for an electric bicycle crank. Background technique [0002] The crank is connected to the frame with a revolving pair and can rotate a full circle around the axis of the revolving pair (that is, the epicyclic pair). A loose crank will often make a rattling noise. When checking the problem of the crank, first turn the crank to the horizontal position, and at the same time press down the cranks on both sides, then turn the crank 180 degrees, and repeat the same action. If the crank will wobble, tighten the crank fixing bolts. The crank of a new bicycle should be checked frequently. A loose crank will often make a rattling noise. When checking the problem of the crank, first turn the crank to the horizontal position, and at the same time press down the cranks on both sides, then turn the crank 180 degrees, and repeat the same action. If the...
