Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing devices, in particular to a laser 3D printing device leveling structure. Background Art

[0002] The laser 3D printing device is a device that adopts the cumulative manufacturing technology, that is, a machine of the rapid prototyping technology. The laser 3D printing device has very high requirements for the balance of the base during printing. At this time, a leveling structure is needed to level the laser 3D printing device. For example, the leveling structure of the 3D printing device with the publication number "CN220031204U" causes the object printed by the device to be tilted synchronously due to the tilt of the device itself when the device is placed on a tilted desktop, thereby causing the printed object to be deformed. When the device as a whole is tilted due to being placed on a tilted desktop, first, the knob is turned to drive the first bevel gear fixedly connected to the connecting shaft through the connecting shaft to rotate synchronously, so that the second bevel gear drives the meshing first bevel gear to rotate synchronously. At this time, the first bevel gear drives the fixedly connected screw sleeve to rotate at the same time, thereby causing the screw connected to the screw sleeve to move up and down, driving the support foot and the foot pad to move up and down synchronously, so that one corner of the device as a whole can sink downward or lift upward; thereby, the device can also maintain a horizontal state when placed on a tilted desktop;

[0003] When the above mechanism is in use, the knob is turned to move the screw up and down, and at the same time the supporting feet and the foot pads are driven to move up and down, causing one corner of the entire device to sink or rise, so that the device can remain horizontal even when placed on an inclined table. However, it can only be leveled on a table with a smaller inclination angle. Once a table with a larger inclination angle is encountered, the leveling effect is not good, so that when the device is placed on a table with a larger inclination angle for use, the device will still tilt to a certain extent, and then the printed object will also tilt synchronously, causing the printed object to be deformed.

[0004] Therefore, we proposed that the leveling structure of the laser 3D printing device can solve the above problems well. Utility Model Content

[0005] The purpose of the utility model is to provide a leveling structure for a laser 3D printing device, so as to solve the problem that when the device proposed in the above background technology is used on a desktop with a large inclination angle, a certain inclination occurs, and then the printed object is also tilted synchronously, resulting in the printed object being deformed.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a laser 3D printing device leveling structure, comprising a base, a hatch is arranged above the base, and suction cups are installed at the four corners of the bottom of the base;

[0007] A laser 3D printing device leveling structure, further comprising:

[0008] The base is rotatably connected to a rotating rod, one end of which passes through the base, and driving gears are fixedly mounted on the outer sides of both ends of the rotating rod. Adjusting gear rings are rotatably connected to the base below the driving gear, and both ends of the two adjusting gear rings are bolted to the bottom of the hatch cover.

[0009] A level is installed on one side of the bottom of the hatch cover, a turntable is fixed at one end of the rotating rod, and a limiting rod is slidably connected to the inside of the turntable, a third spring is installed between the outer side of the limiting rod and the inner wall of the turntable, and a limiting groove is provided at an equal angle to the center point of the rotating rod on the left side of the base.

[0010] Preferably, the two driving gears are meshedly connected with the two adjusting toothed rings, and the two adjusting toothed rings are symmetrically distributed inside the base.

[0011] Preferably, the position of the limiting rod corresponds to that of the limiting groove, and the end of the limiting rod is snap-fitted to the inner wall of the limiting groove.

[0012] Preferably, a fixing block is fixed to the bottom of the hatch cover, a shaft is connected to a bearing located below the adjusting gear ring inside the base, and driven gears are fixed to the outer sides of both ends of the shaft, and a vortex spring is installed between the outer side of the middle part of the shaft and the inner wall of the base, a rack is provided inside the base above the driven gear, a piston plate is sealingly and slidably connected to the inside of the suction cup, and the piston plate and the vortex spring are connected by a traction rope, and a second spring is installed between the top of the piston plate and the inner wall of the suction cup.

[0013] Preferably, the four fixed blocks are evenly spaced at the bottom of the hatch, the tops of the four racks pass through the interior of the base, the positions of the four racks correspond one to one with the fixed blocks, and the tops of the four racks fit with the bottom of the fixed blocks.

[0014] Preferably, protrusions are fixed on both left and right sides of the rack, and the protrusions are slidably arranged inside the base, and a first spring is installed between the bottom of the protrusion and the inner wall of the base.

[0015] Preferably, the rack and the driven gear are meshedly connected, one end of the traction rope is wound around the outside of the shaft, and the other end of the traction rope is fixed to the top of the piston plate.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows: the laser 3D printing device leveling structure rotates the rotating rod forward or reversely according to the inclination angle of the inclined desktop, so that the rotating rod drives the active gear to rotate, and drives the meshing adjustment ring to rotate, so that one end of the adjustment ring extends out of the base and the other end extends into the base, thereby lifting or sinking one side of the bottom of the hatch, so that the device can be placed on a larger inclined desktop and can also maintain a horizontal state. The specific contents are as follows:

[0017] By rotating the rotating rod, the rotating rod drives the driving gear to rotate, and drives the meshing adjusting gear ring to rotate, so that one end of the adjusting gear ring extends out of the base and the other end extends into the base, thereby lifting or sinking one side of the bottom of the hatch cover, so that the device can remain in a horizontal state when placed on a relatively inclined table;

[0018] By pulling the limit rod to separate it from the limit slot at the initial position, the limit on the rotating rod is released, and the rotating rod can be rotated at this time. Then, when the rotating rod rotates, the limit rod is released to reset under the action of the third spring and snap into the corresponding limit slot, so that the rotating rod can be limited after rotation, thereby preventing the rotating rod from deflecting during use;

[0019] (3) When the device is placed on an inclined table, the base is tilted so that the fixed block on one side of the bottom of the hatch can push the rack to move, causing the rack to move and drive the meshing driven gear to rotate. At the same time, the shaft rotates and reels the traction rope, and the traction rope is used to pull the piston plate upward in the suction cup, thereby generating negative pressure inside the suction cup and adsorbing it on the inclined table, thereby improving the stability of the device placed on the inclined table and preventing it from sliding and affecting printing;

[0020] Furthermore, when the device is placed on a horizontal table, the fixed block no longer pushes the rack, so that the rack moves upward and resets under the action of the protrusion and the first spring, and drives the driven gear to reverse, thereby causing the shaft to relax the traction rope. At this time, the piston plate resets under the elastic force of the second spring, so that the suction cup is no longer adsorbed on the table;

[0021] (4) The level ruler can be set up to facilitate the staff to observe whether the device is placed horizontally. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] When the device is placed on an inclined desktop, the base 1 is tilted so that the fixed block 8 on one side of the bottom of the hatch 2 can push the rack 9 to move, and the protrusion 11 moves in the base 1, so that the rack 9 moves and drives the meshing driven gear 14 to rotate, and the shaft 12 rotates and reels the traction rope 15, and uses the traction rope 15 to pull the piston plate 17 upward in the suction cup 3, and then a negative pressure is generated inside the suction cup 3 and adsorbed on the inclined desktop, thereby improving the stability of the device placed on the inclined desktop and preventing sliding from affecting printing.
