Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing technology, and in particular to an adjustment plate mechanism for 3D printing equipment. Background Art

[0002] With the rapid development of 3D printing technology, fused deposition modeling (FDM) is currently the most widely used technology in 3D printers. It is a method that does not rely on lasers as a molding energy source, but instead heats and melts various filaments (such as engineering plastics ABS and polycarbonate PC) and then deposits them into a mold. In some current 3D printers, when printing 3D products, a pneumatic cylinder is used to drive the support cylinder on the piston rod to move telescopically within a protective cover. The leveling plate on the support cylinder moves with the support cylinder to drive the 3D product.

[0003] Generally, a leveling plate is used to hold 3D products. The leveling plate is required to be placed in a balanced manner. After the existing leveling plate is installed, it is manually adjusted to ensure the balance of the installation. However, this method makes it difficult to ensure the accuracy of the installation of the adjustment plate. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a plate adjustment mechanism for 3D printing equipment.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A plate adjustment mechanism for 3D printing equipment includes a cylinder and a connecting seat, wherein the connecting seat is fixedly connected to the piston rod of the cylinder through a clamping structure, and an automatic sensing adjustment plate assembly is mounted on the connecting seat;

[0007] The automatic sensing adjustment plate assembly includes a leveling shaft rotatably installed in a connecting seat, a connecting sleeve fixedly connected to the leveling shaft, a leveling plate body fixedly connected to the top outer wall of the connecting sleeve, a self-locking drive assembly and a level sensor fixedly installed on the front outer wall of the connecting sleeve.

[0008] Preferably, the self-locking drive assembly includes a stepper motor fixedly mounted on the side wall of the connecting seat, a worm fixedly sleeved on the output shaft of the stepper motor, and a worm wheel fixedly sleeved on the leveling shaft and meshing with the worm.

[0009] Preferably, a single-chip microcomputer is fixedly mounted on the side wall of the connecting base, and the level sensor and the stepper motor are both electrically connected to the single-chip microcomputer.

[0010] Preferably, the clamping structure includes a slide groove provided at the bottom of the connecting seat, a bidirectional screw rotatably installed in the slide groove, and two T-shaped positioning clamps symmetrically screwed on two opposite threaded ends of the bidirectional screw.

[0011] Preferably, an anti-slip rotation cap is fixedly connected to the outer wall of one end of the bidirectional screw, and the outer walls of the two T-shaped positioning clamps are slidably connected to the inner wall of the sliding groove.

[0012] The beneficial effects of the utility model are:

[0013] The automatic sensing adjustment plate assembly of the utility model automatically detects whether the leveling plate body installed on the top of the connecting sleeve is in a horizontal state through the level sensor. When the level sensor detects that the leveling plate body is not in a horizontal state, it will transmit a signal to the single-chip microcomputer, which controls the operation of the stepper motor. Then the stepper motor will drive the worm to rotate a certain angle, and then the worm gear engaged with the worm will drive the leveling shaft to rotate a certain angle to automatically level the leveling plate body installed on the top of the connecting sleeve. In this way, the adjustment plate mechanism has an automatic sensing function during installation and use, which can achieve the effect of automatic leveling, thereby ensuring the accuracy of the installation of the adjustment plate and the use effect of the adjustment plate.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Example 1, reference Figure 1-2 A plate adjustment mechanism for 3D printing equipment includes a cylinder 1 and a connecting seat 2, an automatic sensing adjustment plate assembly on the connecting seat 2, and the automatic sensing adjustment plate assembly includes:

[0021] Leveling shaft 3, connecting sleeve 4, the leveling shaft 3 is rotatably installed in the connecting seat 2, and the connecting sleeve 4 is fixedly connected to the leveling shaft 3;

[0022] The leveling plate 5 and the level sensor 6 are fixedly connected to the top outer wall of the connecting sleeve 4, and the level sensor 6 is fixedly installed on the front outer wall of the connecting sleeve 4;

[0023] A self-locking drive assembly includes a stepper motor 7 fixedly mounted on the side wall of the connecting base 2, a worm 8 fixedly sleeved on the output shaft of the stepper motor 7, and a worm wheel 9 fixedly sleeved on the leveling shaft 3 and meshing with the worm 8;

[0024] Furthermore, a single chip microcomputer 10 is fixedly mounted on the side wall of the connecting base 2, and the level sensor 6 and the stepping motor 7 are both electrically connected to the single chip microcomputer 10;

[0025] During the specific implementation of this embodiment: the leveling plate 5 installed on the top of the connecting sleeve 4 is automatically detected by the level sensor 6 whether it is in a horizontal state. When the level sensor 6 detects that the leveling plate 5 is not in a horizontal state, the signal will be transmitted to the single-chip microcomputer 10, and the single-chip microcomputer 10 will control the stepping motor 7 to work. Then the stepping motor 7 will drive the worm 8 to rotate a certain angle, and then the worm gear 9 engaged with the worm 8 will drive the leveling shaft 3 to rotate a certain angle to automatically level the leveling plate 5 installed on the top of the connecting sleeve 4. In this way, the adjustment plate mechanism has an automatic sensing function during installation and use, and can achieve the effect of automatic leveling, thereby ensuring the accuracy of the adjustment plate installation and ensuring the use effect of the adjustment plate.

[0026] Example 2, reference Figure 3-4 This embodiment is optimized based on the first embodiment, specifically: a plate adjustment mechanism for a 3D printing device, further comprising a clamping structure,

[0027] In this embodiment, the connecting seat 2 is fixedly connected to the piston rod of the cylinder 1 through a clamping structure, and the clamping structure includes:

[0028] A chute 12 and a bidirectional screw 13 are provided. The chute 12 is provided at the bottom of the connecting seat 2. The bidirectional screw 13 is rotatably installed in the chute 12. An anti-slip cap 11 is fixedly connected to the outer wall of one end of the bidirectional screw 13.

[0029] Two T-shaped positioning clamps 14 are symmetrically screwed onto two opposite threaded ends of the bidirectional screw 13, and the outer walls of the two T-shaped positioning clamps 14 are slidably connected to the inner wall of the slide groove 12;

[0030] During the specific implementation of this embodiment: the bidirectional screw 13 is driven to rotate forward by the anti-slip rotating cap 11, and then under the limitation of the slide groove 12, the two T-shaped positioning clamps 14 threadedly connected to the bidirectional screw 13 will be aligned and close to each other and clamped on the piston rod of the cylinder 1, thereby enabling the connection seat 2 and the piston rod of the cylinder 1 to be quickly fixed, and the bidirectional screw 13 is driven to rotate reversely by the anti-slip rotating cap 11, and then under the limitation of the slide groove 12, the two T-shaped positioning clamps 14 threadedly connected to the bidirectional screw 13 will move away from each other and quickly separate from the piston rod of the cylinder 1, thereby enabling the connection seat 2 and the piston rod of the cylinder 1 to be quickly disassembled.

[0031] The working principle of the utility model is as follows: first, the bidirectional screw 13 is driven to rotate forward through the anti-slip rotating cap 11, and then, under the limit of the slide groove 12, the two T-shaped positioning clamps 14 threadedly connected to the bidirectional screw 13 will align and move together to clamp the piston rod of the cylinder 1, thereby achieving rapid fixation of the connecting seat 2 and the piston rod of the cylinder 1;

[0032] Secondly, the level sensor 6 automatically detects whether the leveling plate 5 installed on the top of the connecting sleeve 4 is in a horizontal state. When the level sensor 6 detects that the leveling plate 5 is not in a horizontal state, it will transmit a signal to the single-chip microcomputer 10, and the single-chip microcomputer 10 will control the stepper motor 7 to work. Then the stepper motor 7 will drive the worm 8 to rotate a certain angle, and then the worm gear 9 engaged with the worm 8 will drive the leveling shaft 3 to rotate a certain angle to automatically level the leveling plate 5 installed on the top of the connecting sleeve 4. In this way, the adjustment plate mechanism has an automatic sensing function during installation and use, which can achieve the effect of automatic leveling, thereby ensuring the accuracy of the installation of the adjustment plate and the use effect of the adjustment plate.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
