Description

Technical Field

[0001] The invention relates to the technical field of filter housing polishing, in particular to a multi-station filter housing polishing device. Background Art

[0002] A filter is a device or algorithm used for signal processing. Its main function is to separate different frequency components in a signal. Depending on the application and design, filters can be used to remove noise, extract useful signals, or change the spectral characteristics of a signal.

[0003] During the production process of the filter housing, it is necessary to place the metal sheet in a stamping machine according to the design requirements. The stamping machine applies pressure to the metal sheet through the mold to deform it into the required filter housing shape along the contour of the mold. Burrs will be generated on the surface of the filter housing during the stamping process. In order to improve the surface quality and facilitate later processing, the burrs on the surface of the filter housing need to be removed. The corners of the filter housing will be chamfered during the stamping process. It is difficult for traditional polishing devices to polish the curved chamfers, and there is a problem of uneven polishing. Secondly, the polishing disc needs to be replaced when polishing filter housings of different specifications. After each replacement of the polishing disc, a certain degree of debugging is required to ensure the polishing effect and production quality.

The driving wheel 704 rotates to drive the two grinding belts 708 to rotate. At the same time, the lifting device 3 is controlled to start and drive the lifting frame 4 to move back and forth to grind the two sides of the filter housing synchronously. After the side grinding is completed, the driving electric cylinder 609 is controlled to retract, and the two grinding frames 701 are driven to reset according to the above reverse steps, and then the clamping conveying device 10 is rotated to drive the filter housing to rotate 90°.
