Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to an additive manufacturing type 3D printer bracket. Background Art

[0002] Additive Manufacturing (AM), also known as 3D printing, is a technology that creates three-dimensional solid objects by stacking materials layer by layer. This process is based on a digital model, which is created by computer-aided design (CAD) software or scanned to obtain a three-dimensional model of an existing object. The model is then sliced ​​into multiple two-dimensional layers to guide the 3D printer to stack materials layer by layer until a complete three-dimensional object is finally built.

[0003] The printer includes a bracket, a material plate and a driving component. The material plate and the driving component are both located in the bracket. The driving component drives the material plate to move up and down, thereby meeting the needs of lifting and moving the material during the 3D printing process.

[0004] The existing bracket is usually an integrated structure, which makes its loading and unloading complicated. Moreover, the movement stability of the material plate in the bracket is relatively poor, which ultimately affects the quality of the printed product. Summary of the invention

[0005] The purpose of the utility model is to provide an additive manufacturing 3D printer bracket with high stability and compact structure in view of the above problems existing in the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] An additive manufacturing 3D printer bracket, characterized in that it includes a left frame, a right frame, a material plate, a guide assembly and a lifting assembly, the left frame and the right frame are symmetrically arranged and fixedly connected, and a working chamber for performing 3D printing operations is formed between the left frame and the right frame, the guide assembly and the lifting assembly are both located in the working chamber, the material plate is horizontally located in the working chamber and the inner end of the material plate is connected to the guide assembly and the lifting assembly, and the lifting assembly can drive the material plate to move smoothly up and down along the guide assembly.

[0008] The additive manufacturing 3D printer bracket creatively connects the left frame and the right frame to form a working chamber with a hollow interior. The lifting component is used to drive the material plate to rise and fall, and the guide component is used to guide the rising and falling material plate, ultimately ensuring that the material plate moves up and down smoothly in the working chamber.

[0009] Since the precise movement of the material plate is guaranteed, a product with relatively high finished quality can be finally produced.

[0010] In the above-mentioned additive manufacturing 3D printer bracket, it also includes an upper beam and a lower beam arranged horizontally, the two ends of the upper beam are respectively fixedly connected to the top of the left frame and the right frame, and the two ends of the lower beam are respectively fixedly connected to the lower part of the left frame and the right frame.

[0011] The upper and lower cross beams are used to stably connect the left and right frames together.

[0012] In the above-mentioned additive manufacturing 3D printer bracket, the guide assembly includes a guide rod vertically arranged and connected to the working chamber, a sliding bearing is sleeved on the guide rod, and the inner end of the material plate is connected to the sliding bearing.

[0013] Since the material plate is always connected to the guide rod, the material plate can eventually translate stably along the guide rod.

[0014] In the above-mentioned additive manufacturing 3D printer bracket, the number of the guide rods is two, one of which is fixedly connected to the left frame body, and the other is fixedly connected to the right frame body.

[0015] The setting of two guide rods can ensure the smooth movement of the material plate.

[0016] In the above-mentioned additive manufacturing 3D printer bracket, the lifting assembly includes a motor, a screw and a connecting cylinder, the connecting cylinder is fixedly connected to the inner end of the material plate, the connecting cylinder is sleeved on the screw and the two are threadedly connected.

[0017] When the motor drives the screw to rotate, the material plate will not rotate with it, so the material plate will move up and down smoothly in the end.

[0018] In the above-mentioned additive manufacturing 3D printer bracket, the connecting tube is located between the two guide rods.

[0019] This can appropriately improve the structural compactness of the entire bracket.

[0020] In the above-mentioned additive manufacturing 3D printer bracket, the guide rod is provided with two cylindrical sliding bearings, the inner end of the material plate is provided with a snap-fit ​​connection structure, and the sliding bearing is connected to the material plate under the action of the snap-fit ​​connection structure.

[0021] The sliding bearing can reduce the friction resistance between the guide rod and the material plate, ensuring smooth movement of the material plate.

[0022] In the above-mentioned additive manufacturing 3D printer bracket, the snap-fit ​​connection structure includes a partition plate 1, a partition plate 2 and a positioning plate. The upper part of the above-mentioned partition plate 1 has a recessed upper positioning recess 1, and the lower part of the partition plate has a recessed lower positioning recess 1. The upper part of the above-mentioned partition plate 2 has a recessed upper positioning recess 2, and the lower part of the partition plate 2 has a recessed lower positioning recess 2. The sliding bearing located at the upper part of the guide rod is respectively embedded in the upper positioning recess 1 and the upper positioning recess 2 on both sides, and the sliding bearing located at the lower part of the guide rod is respectively embedded in the lower positioning recess 1 and the lower positioning recess 2 on both sides, and the two ends of the above-mentioned positioning plate are respectively fixed to the partition plate 1 and the partition plate 2.

[0023] Two sliding bearings are respectively positioned between the upper parts of the partition plate 1 and the partition plate 2, and between the lower parts of the partition plate 1 and the partition plate 2.

[0024] This can prevent the two sliding bearings from interfering with each other.

[0025] At the same time, since the positioning piece is connected to the partition plate 1 and the partition plate 2, and the partition plate 1 is fixedly connected to the material plate through the fastener, the material plate is finally stably connected to the guide rod through the above structure.

[0026] In the above-mentioned additive manufacturing 3D printer bracket, the number of the positioning plates is two, one of which is connected to the upper part of the partition plate 1 and the upper part of the partition plate 2, and the other is connected to the lower part of the partition plate 1 and the lower part of the partition plate 2.

[0027] Two positioning plates form a connecting unit on one side of the partition plate 1 and the partition plate 2. The number of the connecting units is two, and the two connecting units are respectively located on both sides of the sliding bearing. Such a structure finally connects the material plate stably to the guide rod.

[0028] In the above-mentioned additive manufacturing 3D printer bracket, the thickness of the partition plate 1 and the partition plate 2 is the same and the size thereof is A, the outer diameter size of the sliding bearing is B, the above-mentioned B is greater than A, and the inner side of the positioning piece contacts the sliding bearing surface.

[0029] Such a structure can enable the sliding bearing to be stably connected to the material plate. Since the sliding bearing is connected to the guide rod, the material plate is finally stably connected to the guide rod.

[0030] At the same time, such a structure does not require the thickness of the partition plate 1 and the partition plate 2 to be made relatively large, thereby reducing material consumption and appropriately lowering costs.

[0031] Compared with the prior art, the guide assembly and the lifting assembly of the additive manufacturing 3D printer bracket are connected to the inner end of the material plate, thus reducing the space occupied by the two assemblies, avoiding the printing operation space, ensuring that the printing operation can proceed smoothly, and having relatively high stability.

[0032] At the same time, the guide rod and the material plate are connected through sliding bearings and corresponding snap-fit ​​connection structures. This connection method can avoid the thickness of partitions one and two being too large. On the basis of ensuring the stability of the connection, it also reduces the material consumption of partitions one and two. It has high practical value and compact structure.
