Structure adopting bevel gear set for driving four-sided grinding heads and polishing head with same

Abstract

The invention relates to a structure adopting a bevel gear set for driving four-sided grinding heads. The structure is provided with a main rotating shaft, the main rotating shaft is installed on a gear box, one end of the main rotating shaft is connected with a polishing motor, a main bevel gear is arranged on the main rotating shaft in the gear box and meshes with the four auxiliary bevel gears, the auxiliary bevel gears are arranged on auxiliary rotating shafts, one ends of the auxiliary rotating shafts extend out of the gear box and are provided with the detachable grinding heads, one surface of each grinding head is provided with a disc-shaped polishing disc, the other surface of each grinding head is provided with a connecting shaft, and the connecting shafts are installed on eccentric positions of the auxiliary rotating shafts. According to a polishing head with the structure, the gear box is fixed on a turnover frame, the turnover frame is assembled on the main rotating shaft and is driven by a turnover motor to rotate, and one end of the main rotating shaft extends out of the gear box and the turnover frame to be connected with a polishing motor through a first clutch. According to the structure and the polishing head with the structure, the polishing motor is far away from the polishing area, so that water and dust are prevented from entering the polishing motor, and the polishing motor is protected; and one motor can drive the multiple grinding heads, the structure is simple, manufacturing and assembling are convenient, and maintenance is convenient.

Description

technical field [0001] The invention relates to the field of polishing processing, in particular to a grinding head driving structure and a polishing head with the grinding head driving structure. Background technique [0002] With the development of science and technology, thanks to the development of communication technology, smart products including smartphones and tablet computers have become daily necessities of modern people, especially smartphones, which are owned by almost everyone, and can be used for talking, surfing the Internet, and taking pictures. , video, etc., with diversified functions. In the prior art, the mobile phone case that protects the built-in products inside the mobile phone and forms the appearance of the mobile phone is usually manufactured by injection molding. However, the mobile phone case injected with plastic products has a rough surface and poor bending resistance. The casing performs a coating or painting process. Thinning and thinning i...

Problems solved by technology

However, this kind of mobile phone case polishing by the operator depends on the operator's proficiency and careful attention, so it is difficult to maintain uniform quality, especially for curved surface polishing, the quality difference is greater, and the time required for polishing Long, so has the problem of not being suitable for mass production

That is, the polishing process of mobile phone cases in the prior art is difficult to maintain uniform quality without skilled operators, and the time required for polishing operations is also long, so productivity is reduced

[0003] Later, polishing equipment appeared, and the motor drives the grinding head to rotate and polish. However, since the grinding head is directly assembled on the output shaft of the motor, the distance between the motor and the grinding head is relatively close. In actual processing, the motor is prone to water and dust ingress. , affect the service life of the motor, and even cause the motor to burn out, etc.

At the same time, most of the existing polishing equipment is driven by a motor to work with a single grinding head. When polishing with different precision is required, it is necessary to stop and change the head, which is inconvenient to operate and affects production.
