Description

Technical Field

[0001] This utility model belongs to the field of 3D printing technology, specifically relating to an automatic leveling device for a 3D printing platform. Background Technology

[0002] The structure of a 3D printing equipment mainly consists of three parts: the print head, the gantry, and the platform. The gantry is responsible for moving the print head along the X and Z axes. The platform needs to be level when the 3D printing equipment is in use. The 3D printing equipment cannot be accurately leveled when it is first started and needs to be leveled before it can be used. Traditional leveling devices are mostly manually adjusted, which not only has poor adjustment accuracy but also greatly increases the workload of the operators. Utility Model Content

[0003] The purpose of this invention is to provide an automatic leveling device for a 3D printing platform to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic leveling device for a 3D printing platform, comprising: a machine base and a printing platform body installed above the machine base. Leveling mechanisms for horizontal leveling are provided at each of the four corners between the printing platform body and the machine base. Each leveling mechanism includes an electrically connected lifting mechanism and an electronic level. The lifting mechanism is longitudinally installed between the printing platform body and the machine base. The electronic level is installed at the bottom of the printing platform body. The lifting mechanism, based on lifting, moves one corner of the printing platform closer to or further away from one side of the machine base.

[0005] Preferably, the lifting mechanism includes a mounting base, a ball block, a lifting rod, and a lead screw. The ball block is welded to the top of the lifting rod and is ball-hinged in the mounting base. The top of the machine base has a downward-facing lifting hole to accommodate the rotation of the lead screw. The lifting rod is installed in the lifting hole. The machine base is provided with a driving component to drive the lead screw to rotate. The lead screw drives the lifting rod to move up and down based on its rotation.

[0006] Preferably, the driving component includes a motor, and the bottom end of the lead screw is mounted on the output end of the motor.

[0007] Preferably, a guide groove is provided on the inner wall of the lifting hole along the axial direction, and a guide block is provided on the outer wall of the lifting rod to move up and down in the guide groove.

[0019] 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.

[0020] refer to Figure 1-2As shown, the present invention provides an automatic leveling device for a 3D printing platform, comprising: a machine base 1 and a printing platform body 2 installed above the machine base 1. Leveling mechanisms for horizontal leveling are provided at the four corners between the printing platform body 2 and the machine base 1. The leveling mechanism includes an electrically connected lifting mechanism and an electronic level 3. The lifting mechanism is installed longitudinally between the printing platform body 2 and the machine base 1, and the electronic level 3 is installed at the bottom of the printing platform body 2. The lifting mechanism moves one corner of the printing platform closer to or further away from one side of the machine base 1 based on the lifting mechanism.

[0021] As described above, when using the machine base 1, printing platform body 2 and four leveling mechanisms provided by this utility model, when the four electronic levels 3 detect that the four corners of the printing platform body 2 are not in a horizontal state, the lifting mechanism on the same side is activated, driving one corner of the printing platform body 2 on the same side to be raised and lowered for adjustment. When the four corners are on the same horizontal plane, the four electronic levels 3 are at the predetermined value, at which point the four lifting mechanisms stop, allowing the printing platform body 2 to be in a horizontal state.

[0022] In this utility model, combined with Figure 3 As shown, the lifting mechanism of this embodiment includes a mounting base 4, a ball block 6, a lifting rod 7, and a lead screw 14. The ball block 6 is welded to the top of the lifting rod 7, and the ball block 6 is ball-hinged in the mounting base 4. The top of the machine base 1 is provided with a lifting hole 13 to accommodate the rotation of the lead screw 14. The lifting rod 7 is installed in the lifting hole 13. The machine base 1 is provided with a driving component to drive the lead screw 14 to rotate. The lead screw 14 drives the lifting rod 7 to move up and down based on its rotation.

[0023] Combination Figure 3 As shown, the driving component includes a motor 15, and the bottom end of the lead screw 14 is mounted on the output end of the motor 15.

[0024] Combination Figure 3-4 As shown, the bottom end of the lifting rod 7 has a threaded hole 10 along the axial direction, and one end of the lead screw 14 is screwed into the threaded hole 10.

[0025] As described above, when using the lifting mechanism provided by this utility model, the mounting base 4 in the lifting mechanism provides an installation position for the ball block 6 on the printing platform body 2. The lead screw 14 and the lifting rod 7 are installed on the machine base 1 through the lifting hole 13. When the motor 15 starts, the lead screw 14 rotates, thereby allowing the lifting rod 7 to be adjusted in the lifting hole 13 through the threaded hole 10. When one of the lifting rods 7 is raised, the ball block 6 at the top of the lifting rod 7 rotates in the mounting base 4, thereby causing one corner of the printing platform body 2 to be lifted upward.

[0026] Furthermore, to ensure that the lifting rod 7 can only be raised and lowered within the lifting hole 13, refer to... Figure 3-4As shown, a guide groove 12 is provided on the inner wall of the lifting hole 13 along the axial direction, and a guide block 11 is provided on the outer wall of the lifting rod 7 to move up and down in the guide groove 12. The lifting rod 7 moves up and down in the lifting hole 13 through the guide groove 12 and the guide block 11, and cannot rotate with the lead screw 14.

[0027] In this utility model, combined with Figure 2-3 As shown, one end of the mounting base 4 in this embodiment is provided with a nut 5, and a ball groove 8 for accommodating the ball block 6 is opened between the nut 5 and the mounting base 4. The nut 5 is sleeved on the lifting rod 7.

[0028] Combination Figure 2-3 As shown, the outer wall at the bottom of the mounting base 4 is also provided with an external thread interface 9, and the nut 5 is screwed into the external thread interface 9.

[0029] As described above, when using the nut 5 provided by this utility model, the through hole on the nut 5 is smaller than the outer diameter of the ball block 6. After the nut 5 is screwed onto the mounting base 4 through the external thread interface 9, the ball block 6 is restricted in the ball groove 8. Thus, when the lifting rod 7 is raised or lowered, the printing platform body 2 is horizontally adjusted by rotating the ball block 6 in the ball groove 8.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
