Description

Technical Field

[0001] The utility model relates to the technical field of automobile lamps, in particular to a surface treatment device for an automobile lamp shell. Background Art

[0002] Nowadays, there are many small parts in automobile plastic parts, including automobile lamp housings. In order to match the car during use, it is usually necessary to use a processing device to polish the automobile lamp housing to achieve a beautiful effect on the car's appearance and extend the car's service life.

[0003] However, most of the current surface treatment devices for automobile lamp housings have a complicated clamping method for automobile lamp housings during operation, and are unable to conveniently and stably clamp and position automobile lamp housings of different sizes, and are unable to ensure the stability of subsequent polishing work for automobile lamp housings, and are therefore less practical. For example, the authorization announcement number is CN 219901642 U's utility model patent discloses a surface treatment device for automobile lamp shells. Although it improves the flexibility of the surface treatment device for automobile lamp shells in use, it still has some shortcomings: 1) the device controls the operation of the first motor 4 through the control switch 27, drives the turntable 7 to rotate, and with the cooperation of the arc groove 8 and the lever 10, it can drive four groups of connecting rods 9 and the stop blocks 11 to move outward synchronously. When the four stop blocks 11 are tightly abutted against the inner wall of the automobile lamp shell 14, the automobile lamp shell 14 can be stably supported and fixed. It can be seen from the above that the four stop blocks 11 move outward synchronously, but in practice the inner bottom of the lamp shell is not necessarily a complete circle, which will result in the four stop blocks not being able to guarantee that they are tightly abutted against the inner wall of the lamp shell at the same time, that is, the stability of the support and fixation cannot be guaranteed; 2) the overall structure of the device is large, it occupies a large space resource when not in use, and it is not convenient to move; for this reason, we design a surface treatment device for automobile lamp shells to solve the above technical problems.

[0012] As a further preferred solution of the present invention: the storage chamber is a cylindrical structure.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model sets a pressure value N that meets the fixed clamping requirements. When the third electric push rod is started, the third electric push rod extends and drives the abutment block to move until the abutment block abuts against the inner wall of the lamp housing and generates a certain extrusion force. At this time, the pressure sensor can detect the pressure value. When the pressure value reaches the set pressure value N, the corresponding signal of the pressure sensor is transmitted to the controller, and the controller controls the third electric push rod to stop. At this time, it is the best state that meets the fixed clamping requirements. The four third electric push rods of the device are evenly distributed along the circumferential direction of the top surface of the circular plate and work separately. It is not only suitable for convenient and stable clamping and positioning of automobile lamp housings of different sizes, but also suitable for lamps whose inner bottom of the housing is not a complete circle, and the clamping effect is good and the applicability is higher. In addition, the cooperation of the second electric push rod and the vacuum suction cup facilitates and quickly preliminarily locates the lamp housing for installation, and adjusts the height position of the lamp housing through the second electric push rod, so that the inner wall bottom of the lamp housing and the abutment block are better matched, which enhances the convenience of use and improves work efficiency.

[0015] 2. When the utility model is not in use, the controller controls each electric push rod to retract to the shortest, so that the lifting seat, the circular plate and all the parts on the top of the circular plate can be stored in the storage room, and then the top cover is closed. In addition, the height of the horizontal plate and the polishing equipment is also reduced, so the overall structure of the device becomes smaller, which greatly reduces the space occupied when not in use and is convenient to move.
