Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically a polishing device for processing 3D printed metal parts. Background Technology

[0002] Magnetic polishing, also known as magnetic abrasive polishing, is a technique that uses a magnetic field to drive magnetic abrasives to smooth the surface of a workpiece. It is particularly suitable for processing workpieces with complex shapes and fine structures. Therefore, magnetic polishing equipment is one of the essential devices in the processing of 3D printed metal parts.

[0003] Existing polishing devices have complex structures and unreasonable designs. When the processed metal parts are taken out of the processing barrel, the polishing liquid on the surface of the workpiece is very easy to drip onto the equipment and the working ground, which not only makes the working environment dirty and messy and poses a slippery safety hazard, but also wastes the polishing liquid. To address this problem, the inventors designed a polishing device for processing 3D printed metal parts. Utility Model Content

The support column 21 is fixed to one side of the top of the frame 11, the bearing 22 is fixed inside the top of the support column 21, the connecting shaft 23 is located in the inner ring of the bearing 22, the connecting plate 24 is fixed to the upper surface of the connecting shaft 23, the fixing plate 25 is fixed to the surface of the connecting plate 24 near the processing barrel 12, and the drain basket 27 is located inside the fixing plate 25.

[0020] The frame 11 is the basic support structure of the entire device. The processing barrel 12 is the core container for polishing operations, used to hold the 3D printed metal parts to be polished and the polishing liquid. The support column 21 is the core support for the rotating part 2. The bearing 22 allows the connecting shaft 23 to rotate smoothly in its inner ring. The connecting shaft 23 transmits the rotational motion of the bearing 22 to the connecting plate 24. One end of the connecting plate 24 is fixed to the connecting shaft 23, and the other end is connected to the fixing plate 25. The fixing plate 25 is used to install the drain basket 27. The drain basket 27 drains excess polishing liquid through the mesh, realizing the rapid separation of the workpiece and the liquid.

[0021] A limiting groove 26 is provided inside the fixing plate 25, and the side view of the limiting groove 26 is in the shape of a "U".

[0022] The limiting groove 26 is a snap-on design that allows the drain basket 27 to be quickly and accurately fixed inside the fixing plate 25.

[0023] Handles 28 are fixed on both sides of the upper surface of the drain basket 27.

[0024] The handle 28 is easy for operators to hold, so as to pick up, put down and move the drain basket 27.

[0025] The positioning component 3 includes a positioning frame 31, a positioning post 32, and a connecting hole 34. The connecting hole 34 is opened inside the connecting plate 24. The connecting hole 34 is symmetrically arranged with the central axis of the connecting shaft 23 as the reference surface. The positioning frame 31 is fixed on the surface of the top of the support post 21 away from the drain basket 27. The positioning post 32 is inserted into the inside of the positioning frame 31 and is located inside the connecting hole 34 on the side closer to the positioning frame 31.

[0026] The positioning frame 31 is used for the positioning post 32 to pass through its interior, thereby fixing the connecting plate 24 in the desired position, and the connecting hole 34 is used for the positioning post 32 to pass through the interior of the connecting plate 24.

[0027] A guide block 33 is fixed on the upper surface of the positioning post 32, and the side view of the guide block 33 is convex.

[0028] The guide block 33 is easy for the operator to hold and apply force to lift or press the positioning column 32.

[0029] The positioning post 32 and the connecting plate 24 have movable holes 35 inside, and limit posts 36 are provided inside the movable holes 35. Limit holes 391 are provided inside the positioning post 32. There are two sets of limit holes 391, and the limit holes 391 are distributed along the height direction of the positioning post 32.

[0030] The movable hole 35 allows the limiting post 36 to move within it. The limiting post 36 is used to confine the positioning post 32 inside the connecting plate 24. The limiting hole 391 allows the limiting post 36 to pass through the interior of the positioning post 32.

[0031] A spring 38 is fixed inside the movable hole 35. The spring 38 is fixed to the limiting post 36. A connecting rod 37 is fixed on the surface of the limiting post 36. The connecting rod 37 passes through and is connected to the inside of the connecting plate 24. A guide buckle 39 is fixed on the surface of the connecting rod 37.

[0032] Spring 38 provides elastic force, which pushes the limiting post 36 into the limiting hole 391 under normal conditions to achieve automatic locking. Connecting rod 37 is used to connect and install the limiting post 36 and guide buckle 39. Guide buckle 39 is an operating handle to facilitate pulling the position of the limiting post 36.

[0033] Working principle: When metal parts need to be processed, the metal parts to be processed are first placed inside the processing tank 12, and the required processing liquid is added. The main body 1 of the magnetic polishing machine is started to polish the metal parts. After processing is completed, a pulling force is applied to the guide buckle 39, and the connecting rod 37 drives the limiting post 36 to disengage from the positioning post 32. Then, an upward pulling force is applied to the guide block 33, causing the bottom of the positioning post 32 to move into the connecting plate 24. The force applied to the guide buckle 39 is then released, and under the elastic force of the spring 38, the limiting post 36 springs back to its original position. Positioning pin 32 can be confined inside connecting plate 24. With the cooperation of bearing 22 and connecting shaft 23, a pushing force is applied to fixing plate 25, causing fixing plate 25 to move to the top of processing barrel 12. Then, using the above method, positioning pin 32 is inserted into positioning frame 31 for confinement. Then, through limiting groove 26, drain basket 27 is inserted into fixing plate 25. Then, metal parts inside processing barrel 12 are taken out and placed into drain basket 27 for draining. After draining, a moving force is applied to handle 28 to move metal parts to the desired position.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
