Description

Technical fields:

[0001] This invention relates to the technical field of deburring devices, and more specifically to a device for paint stripping and deburring based on magnetic levitation. Background technology:

[0002] Currently, conventional deburring equipment includes brush-type deburring machines and robotic deburring machines. However, the results are often unsatisfactory, especially in difficult-to-reach narrow areas where tools or brushes cannot reach. These areas require manual grinding, which is slow and prone to quality control due to human error. Regarding paint stripping in the coating process, the company has moved away from the chemical methods used in electroplating to a physical wet pass-through sandblasting process, using 400-mesh white corundum. The corundum is mixed with a solution via a slurry pump, and then the solution is separated into sand and slurry to bombard the product surface. A single pass can remove 50-70 microns of paint. However, this process is inefficient, consumes a lot of consumables, and especially uses a large amount of air, making it unsuitable for current energy-saving and environmental protection requirements. Therefore, a device that can effectively remove paint and deburr is needed. Summary of the Invention:

[0044] The lifting actuator 8 includes a vertical lead screw 81, which is screwed into the lifting prism 62. The lower end of the lead screw 81 is connected to the lower beam plate 15 via a bearing and extends out of the lower beam plate 15 to be fixed with a driven gear 82. A driving gear 83 meshes with the driven gear 82. A servo motor 84 is fixed to the upper end face of the lower beam plate 15.

The solution inside the polishing cylinder 3 can be moved up and down by supporting the upper and lower movement of the chassis 6, and the cleaning and collection mechanism 9 can be used to clean the inside of the polishing cylinder 3.

[0045] The upper beam plate 14 and the bottom plate of the polishing cylinder 3 are respectively formed with limiting holes that are directly opposite to the lifting prism 62. The outer wall of the lifting prism 62 does not contact the inner hole of the turntable 21, so the lifting prism 62 will not interfere with the rotation of the turntable 21, while the upper beam plate 14 and the polishing cylinder 3 can restrict the rotation of the lifting prism 62.

[0046] The polishing cylinder 3 has a drain outlet 31 on one side of the upper part, and the drain outlet 31 is located on the lower side of the upper inclined surface of the supporting base plate 6; a cleaning collection mechanism 9 is provided on one side of the polishing cylinder 3 to cooperate with the drain outlet 31.

[0047] The cleaning and collection mechanism 9 includes a filter square tube 91 fixed on the polishing cylinder 3 at an angle. The upper end of the filter square tube 91 is connected to the drain outlet 31, and the lower end is fixed to a drawer-shaped collection trough 94.

[0049] As the supporting base 6 gradually moves upward, the liquid level in its polishing cylinder 3 also moves upward. The solution and magnetic steel shot 10 can flow into the filter square tube 91 from the drain trough 31. The magnetic steel shot 10 falls along the filter square tube 91, while the solution and the burrs and paint fragments in the solution flow into the guide bucket 92 through the filter tank 911 and are finally discharged through the drain pipe 93.

[0050] The guide bucket 92 is fixed to the outer wall of the polishing cylinder 3; to improve the connection strength of the cleaning collection mechanism 9; a number of inclined support plates 96 are fixed to the bottom of the collection tank 94, and the lower end of the inclined support plates 96 is fixed to the base 1.

[0051] The filter grooves 911 on the filter square tube 91 are horizontal and linearly and uniformly distributed along the side of the filter square tube 91.

[0052] A valve plate 97 is inserted into the lower end of the filter square tube 91. The valve plate 97 can prevent the solution from entering the collection tank 94. Pulling out the valve plate 97 allows the magnetic steel shot 10 at the bottom of the filter square tube 91 to enter the drawer 95, so that the magnetic steel shot 10 can be collected in the drawer 95. In the next operation, the magnetic steel shot 10 in the drawer 95 can be poured into the polishing cylinder 3.

[0053] A liquid inlet pipe 20 connected to the polishing cylinder 3 is fixedly connected to the outer wall of the upper end of the polishing cylinder 3, and solution is introduced into the polishing cylinder 3 through the liquid inlet pipe 20.

[0054] Working principle: This solution utilizes the basic physical magnetic conduction properties. Magnetic steel shot 10 is suspended in a solution (containing cleaning agent and lubricant) within a specially designed polishing cylinder 3. The rotation of the turntable 21 drives several strong magnets 22 to rotate, which in turn attract the magnetic steel shot 10 to rotate, thereby impacting the workpiece in the solution and removing burrs or paint from the workpiece surface.

[0055] Although the magnetic steel shot 10 is attracted and moves downward by the strong magnet 22, it is also affected by the buoyancy of the solution, so that there are suspended magnetic steel shot 10 in each layer; while the workpiece is clamped and fixed in the polishing cylinder 3 based on the pressure plate 55 and the polishing cylinder 3.

[0056] The embodiments described are illustrative of the invention and are not intended to limit the invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the invention; therefore, the scope of protection of the invention should be as set forth in the claims.
