Description

Technical Field

[0001] The utility model relates to the technical field of hinge processing, in particular to a hinge burr processor. Background Art

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow them to rotate relative to each other. Most of the existing hinge burr treatment devices are devices that grind the hinge surface to avoid scratching the user's hands or affecting the use of the hinge when taking and turning. However, when installing and removing the hinge, the burrs at the bolt holes also need to be treated. On the one hand, it can avoid scratching the user's hands when installing and removing the hinge, and on the other hand, it can also avoid affecting the installation of the bolts due to the burrs on the bolt holes.

[0003] The existing device can change the distance between the hinge and the grinding mechanism by moving the workbench, so as to adjust the grinding mechanism according to the thickness of the hinge. However, the existing device still has the following problems:

[0004] 1. The distances between bolt holes of different hinges are different. The grinding components in the existing burr processing device cannot be adaptively adjusted according to the distance between the bolt holes. If different grinding components are replaced, the time for replacing the grinding components will be increased, which will affect the efficiency of burr processing. In addition, multiple grinding components need to be reserved to ensure that multiple hinges can be polished, which is costly. If multiple bolt holes are polished one by one, the operating time of the grinding device will be increased, resulting in a slower efficiency of burr processing.

[0005] 2. The number of bolts of different hinges is also different. Most hinges usually have two or three bolts on the same horizontal line. The existing device cannot adjust the number of grinding heads according to the number of bolts, so multiple grinding is required, which affects the efficiency of burr processing.
