Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to high-precision grinding equipment. Background Art

[0002] With the development of science and technology, various electrical appliances have emerged. Correspondingly, various remote controls have also appeared for the convenience of operation, so that users can remotely operate electrical appliances. The shells of remote controls work together. Most of the current remote control shells are made of one-piece injection molding. Due to the process limitations of injection molding itself, there will be injection molding lines, which are not smooth enough, resulting in the remote control shell not being able to reflect the grade, so the remote control needs to be processed and polished.

[0004] In the above patent, since the support cover is a flexible material made of rubber, a downward force is applied to the remote control during the grinding process, and then the upward thrust of the cylinder reacts to the bottom of the remote control, so that the support cover supports the remote control. In the prior art such as the above patent, the remote control is supported by the cylinder, which improves the stability of the remote control shell during the grinding operation to a certain extent. However, setting more cylinders inside the support cover will not only increase production costs and power consumption, but also make it inconvenient to dissipate heat inside the support cover, posing a safety hazard.
