Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution:

[0022] In this technical solution, a 3D printing placement platform includes a platform base 1 and a platform body 2. The platform base 1 is installed above the base of an external 3D printer, and the platform body 2 is magnetically connected to the upper wall of the platform base 1.

[0023] The platform body 2 includes a mounting frame 21, a platform steel plate 22, a protruding ring 23, a through groove 24, and a magnetic block 25. The lower wall of the mounting frame 21 has a through groove 24, and a magnetic block 25 is inserted into the through groove 24. The magnetic block 25 can be attracted and connected to the platform base 1. A protruding ring 23 is installed on the inner side wall of the mounting frame 21. The platform steel plate 22 can be inserted into the mounting frame 21, and the protruding ring 23 can press the edge of the platform steel plate 22.

[0024] In this technical solution, the platform steel plate 22 is inserted into the mounting frame 21. The platform steel plate 22 can be pressed by the protruding ring 23 on the inner side of the mounting frame 21. At the same time, multiple magnetic blocks 25 are set below the mounting frame 21 to attract the platform steel plate 22, thereby ensuring the level of the platform steel plate 22 and ensuring the quality of subsequent 3D printing.

[0025] Meanwhile, in this article, the platform body 2 is attached to the platform base 1 by magnetic block 25, making it easy to remove the platform body 2 for cleaning.

[0026] In some technical solutions, a first support plate 3 is installed on the side wall of the mounting frame 21, and a gripping groove 4 is opened on the upper wall of the first support plate 3. A rubber pad 5 is fitted to the inner side wall of the gripping groove 4.

[0027] In some technical solutions, the upper wall of the platform base 1 is provided with a positioning groove 6, and a magnet 7 is installed in the positioning groove 6. The magnet 7 can be attracted and connected to the magnetic block 25. The lower wall of the platform base 1 is provided with a slider 8. There are two sliders 8 in total. The two sliders 8 are respectively set on the left and right sides of the lower wall of the platform base 1. The two sliders 8 can be slidably installed in the groove on the external 3D printer base.

[0028] In this technical solution, by setting the positioning groove 6, the magnetic block 25 can be inserted into the positioning groove 6, which can position the platform body 2 and prevent the platform body 2 from shifting after being installed on the platform base 1.

[0029] The slider 8 in this paper has a toothed groove at its bottom, which allows the device to slide back and forth on the base of the external 3D printer under the drive of the motor in the external 3D printer.

[0030] In some technical solutions, a leveling mechanism 9 is installed at each of the four corners of the lower wall of the platform base 1. The leveling mechanism 9 includes a threaded sleeve 91, a screw 92, a servo motor 93 and a motor base 94. The motor base 94 is slidably installed in the inner cavity of the external 3D printer base. The servo motor 93 is inserted and installed on the top of the motor base 94. The servo motor 93 is electrically connected to the external 3D printer. The screw 92 is installed at the output end of the servo motor 93. The threaded sleeve 91 is installed on the lower wall of the platform base 1. The screw 92 is screwed into the threaded sleeve 91.

[0031] In this technical solution, the leveling mechanism 9 can level the platform base 1 and the platform body 2 above it, so that the platform steel plate 22 in the platform body 2 is kept in a horizontal state, so as to avoid affecting the printing quality of the printed parts.

[0032] During leveling, the external 3D printer can control the servo motor 93 to start, causing it to drive the screw 92 to rotate. Through the cooperation of the screw 92 and the threaded sleeve 91, the platform base 1 is leveled.

[0033] In some technical solutions, a second support plate 10 is installed on the side wall of the convex ring 23, a positioning pin 11 is installed on the lower wall of the second support plate 10, and a positioning hole 12 is opened on the upper wall of the mounting frame 21, so that the positioning pin 11 can be inserted into the positioning hole 12.

[0034] In this technical solution, the convex ring 23 can be disassembled to facilitate cleaning of the inner cavity of the mounting frame 21 and avoid affecting the installation of the platform steel plate 22.

[0035] In some technical solutions, the outer wall of the positioning pin 11 is fitted with an anti-slip sleeve 13, which can fit against the inner wall of the positioning hole 12.

[0036] In this technical solution, the anti-slip sleeve 13 makes the positioning pin 11 more stable after it is inserted into the positioning hole 12.

[0037] Working principle: First, the platform steel plate 22 is placed in the mounting frame 21 and the platform steel plate 22 is attracted and fixed by the magnetic block 25. Then, its convex ring 23 is installed on the top of the mounting frame 21 through the cooperation of the positioning pin 11 and the positioning hole 12, and the edge of the platform steel plate 22 is pressed and fixed.

[0038] After the platform body 2 is assembled, it can be installed on the platform base 1. The installation of the device is completed by inserting the magnetic block 25 into the positioning slot 6 and attracting it with the magnet 7 inside.

[0039] Then the device can be leveled using an external 3D printer. After leveling, printing can be performed on the platform steel plate 22.

[0040] After printing is complete, the printed parts can be quickly removed by taking out the platform steel plate 22 and bending it.
