Description

Technical Field

[0001] The utility model relates to the technical field of polishing, in particular to a filter housing polishing device. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. It is a modification process on the workpiece surface using polishing tools and abrasive particles or other polishing media. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but aims to obtain a smooth surface or mirror gloss, and is sometimes used to eliminate gloss.

[0003] Existing filter housing polishing devices are all rotary polishing devices. The staff only needs to place the filter housing on the electric turntable for fixing, and then the turntable will drive the filter housing to rotate and polish. However, the electric turntable can only fix filter housings of a single specification, and cannot fix filter housings of different sizes, which has certain limitations. Utility Model Content

[0008] Preferably, the bottom of the threaded ring is fixedly connected to a limiting rod, and the top of the support column is provided with a slot matched with the limiting rod.

[0009] Preferably, a sliding block is fixedly connected to the bottom of the extrusion plate, and a sliding groove is provided on the top of the electric turntable.

[0010] Preferably, a handle is fixedly connected to the top of the threaded column.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] In the present application, when polishing filter housings of different sizes, the staff first places the filter housing on the base, and then moves the extrusion plate by moving the movable plate, and the four extrusion plates will squeeze and fix the filter housing from four directions. Then the staff grasps the handle and rotates the threaded column, and the threaded column will move the threaded ring downward through the thread, and the threaded ring will cooperate with the support column to squeeze and fix the movable plate, thereby positioning the extrusion plate, so that different filter housings can be fixed.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 , the utility model provides a technical solution:

[0020] A filter housing polishing device comprises a base 1, an electric telescopic assembly 2, a polishing assembly 3 and an electric turntable 4. The above structure is directly cited from the prior art and will not be described in detail herein.

[0021] A movable extrusion plate 5 is installed on the electric turntable 4. The number of the extrusion plates 5 is set to four, and the four extrusion plates 5 are arranged equidistantly in a ring shape with the electric turntable 4 as the center. An anti-slip protrusion 6 is fixedly connected to one side of the extrusion plate 5. The anti-slip protrusion 6 can increase the friction between the extrusion plate 5 and the filter housing. A movable plate 7 is fixedly connected to the top of the extrusion plate 5. A through groove 8 is opened on the inner wall of the movable plate 7. A threaded column 9 is slidably connected to the inner wall of the through groove 8. The threaded column 9 penetrates the through groove 8 and extends a part upward.
