Abstract
Description
Technical Field
[0001] This utility model relates to the field of 3D printing equipment technology, specifically a 3D printing device with a cutting mechanism. Background Technology
[0002] 3D printing (also known as rapid prototyping or 3D printing) is a new manufacturing technology that builds up materials layer by layer to create solid objects. Generally, printing starts with printing a support base first, and then the model to be printed begins. The quality of the base directly affects the quality of the parts to be printed. The base also protects the printed parts. When separating the model from the base after printing, the protection of the base can greatly reduce damage to the model. That is, after printing, the printed part will be connected to the base, and then it is necessary to separate the printed part from the base.
[0003] Currently, 3D printing equipment separates the printed part from the base using a cutting method. However, during the cutting process, the printed part tends to tilt, leading to unstable cutting, uneven cuts, and even damage, thus affecting the cutting accuracy and quality. Therefore, we need to propose a 3D printing device with an integrated cutting mechanism. Utility Model Content
[0004] The purpose of this invention is to provide a 3D printing device with a cutting mechanism, which can separate the base and remove the support without moving the printed part to an external device or workstation, greatly shortening the time cycle from printing to obtaining the final product, significantly improving the overall manufacturing efficiency, ensuring stability during cutting, ensuring a smooth cut, and improving the cutting accuracy and quality, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides: a 3D printing device with a cutting mechanism, including a base, a mounting bracket and a mounting frame mounted on top of the base; a base is movably mounted on the surface of the base via a second module, and a 3D printing head is movably mounted on the surface of the mounting bracket via a lifting module and a first module; an electric push rod is mounted on the surface of the base via an assembly frame, and the extended end of the electric push rod is connected to a cutting mechanism for cutting the printed part; a fixing frame is mounted on one side of the surface of the base located on the second module, and the two ends of the mounting frame are rotatably connected to the fixing frame via mounting shafts; a cutting positioning component for assisting in cutting the printed part is provided inside the mounting frame.
[0006] Preferably, the cutting mechanism includes: an assembly plate connected to the extended end of the electric push rod, and a cutter movably mounted on the surface of the assembly plate; wherein, a positioning slot is provided on the surface of the assembly plate, and the cutter is movably inserted into the inner wall of the positioning slot.
[0007] Preferably, the two ends of the cutter are connected to positioning rods, and the positioning rods are fixedly installed on the surface of the assembly plate by nuts.
[0008] Preferably, the cutting positioning assembly includes: an adjusting screw rotatably mounted inside the mounting frame, and a positioning clamp movably connected to the surface of the adjusting screw; wherein, a guide rod is provided on one side of the adjusting screw, the positioning clamp is slidably connected to the surface of the guide rod, and a drive motor is installed at the center of the mounting frame.
[0009] Preferably, the output end of the drive motor is connected to an adjusting screw, and a bearing plate is provided on one side of the fixing frame, with the top of the bearing plate movably connected to the bottom of the mounting frame.
[0010] Preferably, a connecting shaft is connected to the outer side of the mounting frame, and a positioning shaft is connected to the surface of the base.
[0011] Preferably, an adjusting push rod is movably connected to the surface of the positioning shaft, and the extended end of the adjusting push rod is movably connected to the surface of the connecting shaft.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention utilizes a combination of a base, a fixing frame, a mounting frame, a cutting mechanism, and a cutting positioning component. After printing, the second module moves the base containing the printed part to the cutting separation area. By adjusting the extension of the push rod, the mounting frame can be rotated around the mounting axis on the fixing frame, flipping the positioning clamps to both sides of the printed part. A drive motor drives the adjusting screw, causing the positioning clamps on both sides to move synchronously in opposite directions along the guide rod, achieving automatic centering and stable clamping of the workpiece. This effectively prevents workpiece movement or deformation during cutting, ensuring cutting accuracy. Finally, an electric push rod drives the assembly plate to move towards the printed part, allowing the cutter mounted on the assembly plate to separate or support the printed part, further improving cutting stability, ensuring a smooth cut, and enhancing cutting accuracy and quality.

[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] Please see Figure 1-4 This utility model provides: a 3D printing device with a cutting mechanism, including a base 1, a mounting bracket 2 and a mounting frame 11 mounted on the top of the base 1; a base 7 is movably mounted on the surface of the base 1 through a second module 6, and a 3D printing head 5 is movably mounted on the surface of the mounting bracket 2 through a lifting module 3 and a first module 4; an electric push rod 18 is mounted on the surface of the base 1 through an assembly frame, and the extended end of the electric push rod 18 is connected to a cutting mechanism for cutting the printed part; a fixing frame 8 is mounted on one side of the surface of the base 1 located on the second module 6, and the two ends of the mounting frame 11 are rotatably connected to the fixing frame 8 through a mounting shaft, and a cutting positioning component for assisting in cutting the printed part is provided inside the mounting frame 11.
[0021] It is worth noting that, through the coordinated arrangement of structures such as the base 1, mounting bracket 2, fixing bracket 8, mounting frame 11, cutting mechanism, and cutting positioning components, after printing, there is no need to move the printed part to external equipment or workstation. The base can be immediately separated and the support removed by the built-in cutting mechanism. This greatly shortens the time cycle from printing to obtaining the final product, reduces the steps of workpiece handling and repositioning, achieves efficient integrated operation, and significantly improves the overall manufacturing efficiency. It also improves the stability during cutting, ensures a smooth cut, and improves the accuracy and quality of cutting.
[0022] Specifically, the cutting mechanism includes: an assembly plate 19 connected to the extended end of the electric push rod 18, and a cutter 20 movably mounted on the surface of the assembly plate 19; wherein, a positioning slot 22 is provided on the surface of the assembly plate 19, and the cutter 20 is movably inserted into the inner wall of the positioning slot 22. Positioning rods 21 are connected to both ends of the cutter 20, and the positioning rods 21 are fixedly mounted on the surface of the assembly plate 19 by nuts.
[0023] Furthermore, the electric push rod 18 extends from the assembly plate 19 to control the cutter 20 to cut, the positioning slot 22 is a structure for quick assembly of the cutter 20, and the positioning rod 21 is used to fix the assembled cutter 20.
[0024] The cutter 20 adopts an insert design and is secured with a nut, which facilitates quick replacement of worn cutters, reducing maintenance costs and downtime. The cutting mechanism is driven by an electric push rod 18, which provides stable and controllable linear feed motion, ensuring the smoothness and accuracy of the cutting process. At the same time, the cutter 20 is fixed to the assembly plate 19 by a positioning rod 21 and a nut, which not only makes it easy to install and remove, but also effectively prevents the cutter from shifting or vibrating during the cutting process, thereby ensuring a flat and precise cut and improving the final processing quality of the printed parts.
[0025] The cutting positioning assembly includes: an adjusting screw 13 rotatably mounted inside the mounting frame 11, and a positioning clamp 15 movably connected to the surface of the adjusting screw 13; wherein, a guide rod 14 is provided on one side of the adjusting screw 13, and the positioning clamp 15 is slidably connected to the surface of the guide rod 14; a drive motor 12 is installed at the center of the interior of the mounting frame 11. The output end of the drive motor 12 is connected to the adjusting screw 13; a support plate 9 is provided on one side of the fixing frame 8, and the top of the support plate 9 is movably connected to the bottom of the mounting frame 11.
[0026] In addition, the drive motor 12 can be a dual-axis motor, which synchronously drives the adjusting screws 13 on both sides to control the positioning clamp 15, which can further improve the clamping stability of the positioning clamp 15. The adjusting screw 13 is a structure that transmits the positioning clamp 15 through the drive motor 12, so that the positioning clamp 15 is clamped. The bearing plate 9 supports the mounting frame 11 after flipping, ensuring the positional stability of the positioning clamp 15 after flipping.
[0027] The cutting positioning assembly, consisting of a drive motor 12, an adjusting lead screw 13, a guide rod 14, and positioning clamps 15, can adaptively clamp and fix the workpiece according to its size and shape. The drive motor 12 drives the adjusting lead screw 13, causing the positioning clamps 15 on both sides to move synchronously in opposite directions along the guide rod 14, achieving automatic centering and stable clamping of the workpiece. This effectively prevents workpiece movement or deformation during cutting, ensuring cutting accuracy. It is applicable to various sizes of printed parts, enhancing the equipment's versatility and practicality.
[0028] A connecting shaft 16 is connected to the outer side of the mounting frame 11, and a positioning shaft 10 is connected to the surface of the base 1. An adjusting push rod 17 is movably connected to the surface of the positioning shaft 10, and the extended end of the adjusting push rod 17 is movably connected to the surface of the connecting shaft 16.
[0029] The connecting shaft 16 is a structure that connects the adjusting push rod 17 to the mounting frame 11. This allows the positioning clamp 15 mounted on the mounting frame 11 to be flipped by adjusting the push rod 17, effectively preventing positional interference during the printing process.
[0030] The printhead achieves multi-degree-of-freedom movement through a lifting module and a first module, while the base moves horizontally through a second module. The cutting mechanism shares the base platform space with the printing area. The mounting frame can rotate around the mounting axis, and its angle can be adjusted by adjusting the push rod in conjunction with the positioning axis, potentially to avoid obstacles during the printing process or optimize the cutting position. This design allows the device to integrate multiple functions within a limited space, reducing its footprint while ensuring that each functional module operates independently and in a coordinated manner.
[0031] By controlling the lifting module 3, the first module 4 and the second module 6, the 3D printing head 5 and the base 7 used to support the printed parts can be moved to achieve the effect of three-dimensional printing along the X / Y / Z axes.
[0032] After printing, the base 7 with the printed part is moved to the cutting and separation area via the second module 6. The adjustable push rod 17 extends and controls the mounting frame 11 to rotate around the mounting axis on the fixed frame 8, flipping the positioning clamps 15 to both sides of the printed part. The drive motor 12 drives the adjusting screw 13, causing the positioning clamps 15 on both sides to move synchronously in opposite directions along the guide rod 14, realizing automatic centering and stable clamping of the workpiece, effectively preventing the workpiece from moving or deforming during cutting, and ensuring cutting accuracy. Finally, the electric push rod 18 drives the assembly plate 19 to move towards the printed part, so that the cutter 20 installed on the assembly plate 19 separates or supports and removes the printed part, improving the stability during cutting, ensuring a flat cut, and improving the cutting accuracy and quality.
[0033] 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.
