Description

Car car light surface treatment device Technical Field The invention relates to the technical field of car lamp surface treatment, in particular to a car lamp surface treatment device. Background The automobile lamp is used as a core component for vehicle illumination and signal indication, the appearance transparency and the optical performance of the automobile lamp are directly related to driving safety, the surface of the automobile lamp is easily subjected to ageing phenomena such as scratch, yellowing, atomization and the like under severe environmental conditions such as ultraviolet rays, acid rain, sand dust, car washing friction and the like in the use process, the light transmittance is reduced, the light scattering is caused, the night driving safety is seriously influenced, and in addition, the surface of the automobile lamp is subjected to polishing and polishing treatment in the scenes such as after-sale cosmetology, accident repair, car lamp renovation and the like of the automobile lamp, so that the automobile lamp becomes a key process for recovering the transparency. At present, the polishing treatment of the surface of the car lamp is mainly carried out by adopting polishing sponge to cooperate with a polishing machine, namely, polishing agent is smeared on the sponge in advance, then polishing treatment is carried out, and the sponge polishing wheel is widely applied to various curved surface polishing operations due to the advantages of softness, good laminating property, uneasiness in scratching substrates and the like, in the prior art, a connecting mode between the polishing sponge and the polishing machine mostly adopts a magic tape (also called a sticking buckle tape) structure, namely, a rigid backboard is fixedly arranged at the end part of a driving shaft of the polishing machine, a hook surface is arranged on the surface of the backboard, a rough surface matched with the polishing sponge is arranged on the back surface of the polishing sponge, and quick installation and replacement of the sponge wheel are realized through hooks Mao Niege. When the sponge polishing wheel is used for polishing, the center position of the sponge is required to be strictly aligned with the axis of a driving shaft of the polishing machine, otherwise uneven polishing pressure distribution is caused, uneven grinding is generated, polishing quality is affected, however, the existing sponge mounting mode lacks an auxiliary centering positioning structure, an operator needs to align and attach the rough surface on the back surface of the sponge wheel with a hook surface on a back plate when the sponge is mounted, as the hook surface on the back plate is required to be contacted with the sponge wheel to generate adhesive force, the operator cannot correct the position through fine adjustment like rigid connection, if the center of the sponge is deviated from the center of the back plate, the sponge is required to be torn off from the back plate and is re-attached after re-alignment, the whole centering operation lacks a definite positioning reference, and repeated tearing attachment not only affects operation efficiency, but also possibly causes the decrease of the adhesive force of the hook surface on the back plate, and further affects the connection stability of the sponge wheel in the high-speed rotation process. Disclosure of Invention Aiming at the defects of the prior art, the invention provides an automobile lamp surface treatment device, which aims at solving the problem that the polishing sponge in the prior art is difficult to align with the axle center rapidly. In order to achieve the above purpose, the technical scheme is that the automobile lamp surface treatment device comprises a polishing machine main body and polishing sponge, wherein a cavity is formed in the polishing machine main body, a motor is fixedly installed in the cavity, a disc is arranged on one side of the polishing machine main body, an installation rod is fixedly installed between the output end of the motor and the disc, an adhesive plate used for adhering the polishing sponge is fixedly installed on one side of the disc, which is far away from the polishing machine main body, a circular shell used for pre-positioning the polishing sponge is sleeved outside the disc, four small installation grooves and one large installation groove are formed in one side of the adhesive plate, one end of the installation rod, which is located in the cavity, of the installation rod is sleeved with a U-shaped pushing piece in a sliding mode, two ends of the U-shaped pushing piece are respectively located in the two small installation grooves, a reciprocating piece is arranged in the installation rod, a connecting piece is arranged between the reciprocating piece and the U-shaped pushing piece, the U-shaped pushing piece is used for pre-adhering and pre-separating the polishing sponge, and the U-shaped pushing piece is used for pushing the p
